Over the past two decades, screw compressors have undergone revolutionary changes several times: for instance, they now adopt inverter technology. Inverter technology can manage the part load energy efficiency of HVAC&R systems very well, and has become a consolidated energy efficient solution in the industry.
Shuangliang initiated the global launch of a new oil-free magnetic bearing inverter centrifugal chiller in August 2020. The new-type chiller is different from the previous model and applies a Danfoss Turbocor TT series magnetic bearing centrifugal compressor. The cooling capacity of this new product line ranges from 100 to 1,600 USRT.
‘DXS’ Hitachi single-effect double-lift absorption chiller, which was developed under the commissioned research of New Energy and Industrial Technology Development Organization (NEDO), Japan, is a hot-water-driven absorption chiller which recovers unused thermal energy for cooling effectively, by utilizing thermal energy down to as low as approximately 55°C.
Panasonic Appliances Air Conditioning Europe has newly added cooling-only units to the currently available ECOi-W series heat pump chillers. The ECOi-W provides a wide variety of reliable and powerful HVAC chiller solutions to meet the needs of hotels, commercial and industrial premises.
Data on 2019 from AFEC, the Spanish air conditioning equipment manufacturers’ association, show that residential system sales reached over €512 million (US$ 557 million). The residential sector comprised: portable and window units; floor/ceiling/wall units; wall-mounted single-and multi-split units; ducted units; water chillers; fan coils; multitask heat pumps; compact heat pump water heaters; and split-type heat pump water heaters.
According to statistics from Yonhap News Agency, the South Korea Central Bank indicates that the country has seen GDP growth of 2% year on year in 2019. The first quarter saw GDP growth of 1.7% year on year, while the second and third quarters saw an actual growth rate of 2%, and the fourth quarter saw a slightly enhanced growth rate of 2.3%. The growth rate per quarter has signs indicating recovery.
According to the Economic and Social Research Institute (ESRI), Cabinet Office, Government of Japan, the real GDP growth in fiscal year 2019 (ending March 2020) was 0%. A breakdown of central chilled water system shipments shows that positive-displacement type chillers decreased by 1.7%, centrifugal chillers decreased by 20.2%, absorption chillers increased by 9.8%, AHUs decreased by 6.9%, and FCUs increased by 1.4%.
Chiller manufacturers are generally reluctant to share shipment data, making it difficult to accurately estimate the scale of the Indian chiller market. Different manufacturers follow different financial years, hence compiling data for a given year requires some extrapolation and approximation.
