The United States may be one of the largest air conditioner markets in the world, but its share of the world VRF market is still small. Japanese manufacturers have, however, worked for the last 10-odd years to increase recognition for VRF, and these efforts are paying off. More recently, non-Japanese manufacturers have also started selling VRFs and are ramping up their market participation.

Technical Trends of Rotary Compressors

— Continued from March Issue   Contributed by Masataka Yamane, HVACR advisor Multiple Compressor Types   Two-piston   Rotary compressors take in, compress, and discharge refrigerant in one rotation. The pressure in the compression chamber during one rotation changes depending on the rotation angle. This creates a large difference in the rotational torque of the electric motor and the compressive force (load torque) in the compression chamber, resulting in an uneven rotational speed and increased compressor vibration.   In particular, when the compressor is operating at a low speed, vibration is noticeable. In order to solve this problem, a two-piston type rotary compressor was developed. The two-piston type sets the two pistons apart at a 180 degree angle in order to balance the mass of two pistons, leading to small torque fluctuations and a substantial decrease in vibration in the direction of rotation. The two-piston type compressor can be produced on existing production lines, giving it the advantage of relatively low cost. As a result, the two-piston rotary compressor is widely used today for inverter air conditioners.   One-piston   Production costs for two-piston compressors are higher than those of one-piston compressors. With a view to reducing costs, manufacturers have worked on ways to achieve low-vibration operation with inverter-driven one -piston rotary compressors. They employed power electronics technology to achieve torque control, which reduces vibration by aligning the load torque created from compression with the electric motor torque. This enabled one-piston rotary compressors to also operate at low speeds with little vibration, although one-piston types are inferior in level to the two-piston type rotary compressor.   Swing Type   Swing-type rotary compressors are a family of rolling piston rotary compressors and have a unique design around the vane. A standard rotary compressor has separate piston and vane parts, but a swing-type compressor has an integrated piston and vane, with compression occurring in the cylinder. This is said to achieve advantages including reduced gas leaks, high efficiency regardless of capacity size, little vibration, and high durability.   Variable Cylinder Type   The variable cylinder rotary compressor was developed from the two-piston rotary compressor. During low-load operation, inverter air conditioners may operate intermittently even when the capacity is reduced to a minimum level. The variable cylinder rotary compressor can operate continuously with low energy consumption even at low-load operation. It reduces its compressor capacity by half to do this, by retracting the vane of one of its two compression chambers into the cylinder’s spring during low-load operation to stop the compression action. This enables continuous compressor operation even during low load operation of the inverter air conditioner. Eliminating intermit-tent operation enables comfortable and energy-efficient air conditioning during times of low load such as in between seasons.   Two-stage Compression   A two-stage compressor able to compress high- pressure refrigerant such as CO2 divides compression into two stages using one two-piston rotary compressor. The compressed CO2 in the first compression chamber is delivered to a second compression chamber, where it is com-pressed further. Vapor refrigerant is injected from a gas-liquid separator located between the discharge port of the first chamber and the second chamber. This keeps the discharge temperature of the CO2 refrigerant from overheating and enables compression of the CO2 refrigerant, which is difficult to compress sufficiently in one stage. This two-stage compression type rotary compressor is used in heat pump water heaters capable of supplying high-temperature hot water.   Scrotary   The so-called scrotary compressor has been developed and adopted in commercial CO2 heat pump water heaters. It uses a two-stage compression refrigeration cycle with a gas-injection cycle. Due to the properties of this refrigeration cycle, the differential pressure is higher on the high-stage side than on the low-stage side. Taking this into account, the hot water heater uses two-stage compression with a rotary compressor design on the low-stage side, which demonstrates efficiency when there is low differential pressure, and a scroll compressor design on the high-stage side, which demonstrates efficiency when there is high differential pressure, attached to either end of the electric motor. This structure is able to substantially increase heating performance when the outdoor temperature is low. Developed by Mitsubishi Heavy Industries Thermal Systems, this compressor was used for heat pump water heaters, and then applied to 10-hp condensing units using CO2 refrigerant in April 2017, and 20-hp condensing units will be released in May 2018. Its applications are expected to further expand.   Larger Capacities   In general, rotary, scroll, and screw compressors each have their own capacity range, but each type has also been expanding the upper limit of its capacity range in recent years. Rotary compressors have posed a challenge at higher capacities, but the development of two-piston types have led to rotary compressors with larger capacities that offer high efficiency with low vibration and leakage. Large rotary compressors are now available up to 20 hp. These larger capacity rotary compressors are often used in variable refrigerant flow (VRF) systems, modular chillers, and commercial heat pump water heaters.   Low-load Operation   In the case of packaged air conditioners (PACs) and VRF systems for shops and office buildings sold in  Japan, the revised Japanese Industrial Standards (JIS) in 2015 adopted a new calculation method for the Annual Performance Factor (APF) to include the lowest capacity in order to appreciate the system’s efficiency under more practical operating conditions. In this context in Japan, two -piston type rotary compressors are increasingly used because they can operate more efficiently at low load than scroll compressors. It is forecast that in the future, China and Europe will adopt the new APF calculation method for PACs that is used for the revised APF in Japan. In the field of relatively low-capacity PACs, the use of two-piston type rotary compressors is expected to expand further.   Moreover, in the context of increasing numbers of highly airtight and highly heat insulated residences, the improvement of operating efficiency during low load is becoming a major issue, due to the higher frequency of load occurring between the medium-to-small capacity that is smaller than the rated capacity. In order to address this issue, the above-mentioned variable cylindrical rotary compressors are being adopted, in addition to a reduction in the minimum number of revolutions of compressors, the adoption of optimum cylinder volume, and the improvement of mechanical efficiency in the small-to-medium capacity ranges, and improved mo-tor efficiency. Motors have become more efficient and lighter by shifting from ferrite magnet to a rare earth magnet, and from distributed to concentrated winding.   Meanwhile, scroll compressors generally tend to become less efficient due to over-compression during low-load operation compared with rotary compressors. In recent years, countermeasures have been adopted to improve efficiency at the low-load operation, including a relief mechanism that is triggered when over-compression occurs.   New Refrigerants Over the last few years, there have been moves to adopt low-GWP refrigerants as a way to fight global warming. Rotary compressors also need to adapt to these refrigerants, and compressor reliability is improving, partly owing to better parts durability and the development of lubricating oils for new refrigerants.   Future Developments   The number of papers and patents on rotary compressors has fallen sharply compared with the peak of activity, and there has been scant release of new technologies. However, companies are still thought to be working behind the scenes to improve compressor performance, to enhance manufacturing efficiency and processing precision, and to reduce costs.   As with other compressor types, rotary compressor technology development would be welcomed in the coming years. In particular, the development of rotary compressors that demonstrate higher performance in regions with extremely cold and hot climates would be a major breakthrough. With the advent of the Internet of Things (IoT) and Artificial Intelligence (AI) adopted in many sectors, it is expected that technology adapted to these trends will emerge in the near future and will improve reliability and APF, as well as lengthening the lifespan of rotary compressors.

Southern Hemisphere AC Market Gradually Recovers in 2017

In the Northern Hemisphere, the air conditioner sales season will begin soon, while in the Southern Hemisphere the sales season will soon be over. JARN carried out questionnaire and interview surveys of global leading air conditioner manufacturers and asked about the Southern Hemisphere market situation in 2017 and 2018.
After a stagnant situation, there is now a silver lining in the Southern Hemisphere air conditioner market. Australia showed favorable growth and acted as a driving force in 2017. The Brazilian market has been showing signs of recovery recently. In Africa, several markets have growing potential, and these markets expected to bring business opportunities for air conditioner manufacturers.
In Australia and New Zealand, the number of immigrants has been increasing since 2015, but the increasing pace has now slowed, mainly due to regulatory policies. With Fujitsu General split air conditioners displayed at a shopping center in Springvale, Australia higher populations, the construction industry achieved steady results in 2017. The region as a whole experienced a milder winter and a milder summer compared with 2016.
In Australia, the air conditioner market scale has been expanding in recent years. Also in 2017, both room air conditioners (RACs) and packaged air conditioners (PACs) recorded about a 20% growth. Air conditioners sold in Australia are mainly imported from Southeast Asian countries.

The RAC market in 2017 showed healthy growth during heating season from April to September. For cooling demand, RAC sales got off to an early start in September. In the previous 2016 –2017 summer, heat waves hit Australia and many users couldn’t get their air conditioners quickly due to lagging installation services. Users rushed to buy RACs earlier in 2017, leading to the early start in sales. However, in the middle of the summer, from December 2017 to February 2018, the weather became unstable and the growth of RAC demand slowed.
It is estimated that housing construction is decreasing, which will shift the air conditioner demand from new installation to replacement demand in Australia.
In Australia, almost all air conditioners excluding window type RACs are of an inverter type. For indoor units, the ducted type is popular for both residential and commercial use PACs. Wall-mounted type RACs and ceiling cassette and ceiling concealed types PACs are also popular.
Japanese manufacturers lead the Australian RAC market and include Daikin, Fujitsu General, Panasonic, Mitsubishi Electric, and Mitsubishi Heavy Industries (MHI). They focused on the Australian market, especially in 2017 when the Southeast Asian market was stagnant, in order to increase their sales. Local manufacturers including ActronAir and Kelvinator are also increasing their market share with price-competitive products in mass retailer channels.

Daikin utilizes dealer and professional shop channels in Australia and has been focusing on replacement demand with them. Its ducted type Sky Air PACs for single-family and multi-family dwellings showed strong sales in 2017.
In February 2018, Fujitsu General Australia started the construction of its head office comprising an 11,093 m2 building and an 8,500 m2 distribution warehouse. The new offices and warehouse will improve operational and distribution efficiency across the
Fujitsu General network, nationally. The company also opened the first Fujitsu General Air Conditioning Centre in the Asia Pacific region on March 10, 2018 in Australia. The store will feature multiple zones for consumers to experience different Fujitsu General air conditioning systems, from wall-mounted units, to multi-split systems and ducted solutions.
MHI adopts a direct selling sys-tem through its subsidiary MHI Air-Conditioning Australia (MHIAA). The company is expanding its product line up imported from its Thai factory.

Led by Japanese manufacturers, the number of R32 RACs is increasing in Australia. Daikin has adopted R32 refrigerant for all of its newly released single - split models. The company is also shifting its multi-split RACs to R32 models. For PACs, R410A models remain, but a switch to R32 is planned within a year.
With various R32 models, Fujitsu General plans to expand R32 RACs incorporating a Wi-Fi control function. Mitsubishi Electric started to sell cooling-only R32 RACs from August 2017. MHI is proceeding with Minimum Energy Performance Standard (MEPS) registration for R32 models.
The Australian government plans to put in force the new MEPS for air conditioners from April 2019. According to the plan, the new MEPS will adopt the Seasonal Energy Efficiency Ratio (SEER) for rating air conditioner energy efficiency. The current Energy Rating Label will be replaced with the Zoned Energy Rating Label.
New Zealand
New Zealand RAC market remained mostly the same in 2017 compared with 2016, while PACs increased thanks to a stable construction market. The house builder sales channel is expanding in the country.

As in Australia, almost all RACs and PACs are of an inverter type. For RACs, R410A models are popular. For PACs, ceiling-concealed type R410A units are the main sellers. The New Zealand government has developed the New Zealand Emissions Trading Scheme (NZ ETS) as principal policy in response to cli-mate change. Backed by this policy, R410A refrigerant is being replaced by R32.
Japanese manufacturers dominate the market and include Daikin, Fujitsu General, Panasonic, Mitsubishi Electric, and Toshiba Carrier.
I n November 2016, Daikin opened its sales subsidiary Daikin Air Conditioning New Zealand (DNZ) to offer air conditioning products and maintenance services.
Latin America
Air conditioners sold in Latin America are mainly imported from Asian countries centering on China. The market scale of each country on a unit basis is not very large, so manufacturers are not aggressively investing in development. Against this backdrop, many manufacturers purchase products from Chinese manufacturers on an original equipment manufacturing (OEM) basis.
In countries like Panama and Columbia, leading professional air conditioner stores, namely air conditioner distributors, are selling products under their original brands, most of which are also OEM products from China.
Chinese manufacturers such as TCL and AUX are active in Argentina and other countries in Central and South America.
The Brazilian economy is showing signs of a gradual recovery. The Brazilian RAC market increased to 2.5 million units in 2017. RAC imports from China also increased, driven by OEM products from local private brands.
The first quarter of 2018 is estimated to have increased by about 5% compared with the previous year. Many manufacturers expressed that they are fully confident that 2018 will be a good year.
In Brazil, non-inverter wall-mounted single- split RACs are mainstream in the market. Of them, the cooling-only type is estimated to have a 60% share, and heat pump type a 40% share. Low-priced RAC and PAC models are popular. The northeast area and Rio de Janeiro zone are cost-competitive markets.
To gain tax benefits from local production, Daikin, Gree, Midea-Carrier, Whirlpool, Electrolux, LG, and Samsung all have air conditioning plants in the Free Economic Zone of Manaus, Brazil. Fujitsu General partnered with a local manufacturer and started local assembly of air conditioners in fiscal year 2016 (end of March 2017) and plans to expand locally produced models.
Online sales of air conditioners in Brazil are about 10% of total sales. As the installation service system has not yet been established, at this stage online sales in the country are unlikely to grow to the same level as in China that has a big online sales scale. Many manufacturers are accelerating acquisitions of distribution channels to promote products and improve service quality.
Chinese and South Korean manufacturers lead the market and include Midea Carrier, Gree, Samsung, and LG. Electrolux from Europe is also active in the market. Gree is expanding its air conditioner sales in Brazil. Haier has increased promotion of its own brand in Brazil.
Midea Carrier is a joint venture (JV) of Midea and Carrier. It re-leased energy efficient Comfee series new split air conditioners in the Brazilian market in October 2017.

LG shifted all air conditioners to inverter models, and this move has expanded its sales and also expanded the inverter market.
Fujitsu General focuses on promoting larger capacity models including wall-mounted single- splits, multi-splits, and PACs. From fiscal year 2018, the company will bring new wall-mounted models of 36,000 BTU and 45,000 BTU multi-splits that connect to up to six indoor units to the local market.
The Brazilian government plans to enforce new MEPS for single-split RACs and PACs during fiscal year 2018. According to the new MEPS, the threshold value will increase to an energy efficiency ratio (EER) of 2.81.

South Africa
In South Africa, the construction market is active. Large shopping malls are being constructed and there are increasing numbers of commercial buildings in the Sand-ton area in Johannesburg, the largest city and business center of the country. Johannesburg is located in a highland region and in the past, there was no need to use air conditioners. However, there have been more hot days in summer around Johannesburg in recent years, and air conditioner demand has been increasing.
The RAC market in South Africa reached 167,000 units in 2017.
For RACs, heat pump type inverter models are mainly sold. The share of inverter RAC models is estimated at three-quarters of the market. For PACs, the inverter rate increased to about 95%. Both RAC and PAC markets have already shifted from R22 to R410A refrigerant.
Daikin, Samsung, LG, Mitsubishi Electric, Midea, and Carrier lead the market. Panasonic entered the market and is gradually expanding its product range. Fujitsu General offers products mainly through contractor and professional routes.
The Algerian RAC and PAC markets in 2017 both grew by around 15%, respectively.
From 2018, the Algerian government banned imports of RACs in order to nurture local production and local brands. Accordingly, localbrands have been expanding their market share, especially in the wall-mounted type RAC segment. Several foreign manufacturers are setting up RAC production bases in Algeria. France -based Brandt set up a new factory covering an area of about 1 million m2. Samsung has partnered with a local manufacturer and will start local production.
Condor, a local giant, is leading the market, followed by Midea, Brandt, LG, and Starlight. Condor has over 100 showrooms and opened the latest one in Benin in West Africa in March 2018. Condor started direct sales, skipping the usual intermediate players from dealers and mass retailers, to in-stallers. Fujitsu General focuses on PAC sales through distributors, by setting up showrooms on a brand basis.
The Algerian government plans to introduce a new energy law that is expected to impose a tax from 5 to 30% on air conditioners according to their energy efficiency. Accordingly, highly efficient inverter air conditioners are expected to expand their share from the current penetration rate of about 70%. In Algeria, RACs and PACs commonly use R410A refrigerant.
The air conditioner market scale in Egypt amounted to about 523,000 units in 2017.
Heat pump type low-end air conditioners are popular in the market. Foreign manufacturers including
Carrier, Sharp, and Gree, and local manufacturers including Unionair and Power lead the market.
In addition to local players, Carrier, LG, Samsung, and Gree own production bases in the country. In 2004, Sharp started technical co-1laboration with a local manufacturer ElAraby to assemble RACs for Egypt and surrounding countries. Unionair and Power also aggressively export their air conditioners to other countries in Africa.
Unionair is a local home appliances company and offers split type, window type, floor-standing type, and ducted type RACs. Daikin Europe established its sales subsidiary Daikin Air-conditioning Egypt (DAEG), a JV with BPE partners, and started operations in August 2016. Fujitsu General sells its air conditioners mainly through directly managed shops, dealers, and super markets. Midea sells its RACs using the Fresh brand.
The Nigerian air conditioner market was 596,000 units in 2017, and RACs accounted for 557,000 units.
Cooling-only low-end models are the biggest sellers. Price competition is fierce, especially for floor-standing types.
LG, Samsung, Panasonic, Haier, and Midea lead the market.

SWEP BPHEs Generate Strong Business in Asia

During HVAC&R JAPAN 2018 held in February in Chiba Prefecture, JARN interviewed Tommy Simonsen, vice president marketing of SWEP International, and Joakim Fahlstedt, representative director of SWEP JAPAN, to gain an insight into SWEP’s business in Asia.

JARN (J): First of all, could you briefly introduce SWEP’s heat exchanger business?
SWEP (S): SWEP is a world-leading supplier of brazed plate heat exchangers (BPHEs) for heating, ventilation, and air conditioning (HVAC) and industrial applications. Designed to make the most efficient use of energy, materials, and space, the technology is quickly gaining ground around the world, with SWEP at the forefront of developments.
 SWEP is known for providing market-leading technology within our core markets. This is the result of more than 30 years of close collaboration with customers around the world. They have played an essential part in driving our development and efficiency, and in building up the application expertise that has allowed us to achieve leadership.
J: Could you please tell us the result for SWEP’s Position in Asia including China, India, Japan, and South Korea in 2017?
S: SWEP is in the leading position in these markets and some recent surveys verify such a leading position in China. In 2017, SWEP had growth in line with or above the market and industries it serves, such as in the HVAC sector’s air conditioning and heat pump markets in China. Both Japan and South Korea were showing double -digit growth in 2017 and especially in South Korea the results were outstanding among our major global accounts.

SWEP representatives at its booth during HVAC&R JAPAN 2018

J: How do you see market growth in Asia in 2018?
S: Asia is expecting moderately slower growth than in 2017 from the softening demand in China driven by Coalto-Electricity and air conditioning products. However, India is expected to grow faster after 2017, a year negatively impacted by demonetization and new Goods and Services Tax. Japan and South Korea are expected to grow at the same or at a faster pace than in 2017 thanks to the continuing positive general development in their economies. Above all, our export-driven accounts will lead the growth path.

J: SWEP has operations around the world. What percentage of your business does Asia account for?
S: Over a quarter of our total business is located in Asia, in which the biggest markets are in China followed by Japan, South Korea, and India.

J: What shares of your business in Asia do refrigeration and air conditioning account for?
S: Over 50% of SWEP’s Asia business is dedicated to these two segments.

J: BPHEs are a key part of your business. Northern European manufacturers are very strong in the heat exchanger industry. Are there any special reasons?
S: It is difficult to mention any particular reason. However, it could be fair to note that Nordic countries are focused on energy efficiency since they have strong demand for heating residences in long winters combined with increased costs of energy. This forms the basis of developing ever more efficient systems, of which heat exchangers are an integral part of.

Midea Strongly Promotes R290 ACs Targeting Environmental Challenges
