Failures in GSHPs
Numerous ground-source heat pump (GSHP) systems in the United Kingdom are failing to meet target performance because of faults in design, installation and operation. This is the conclusion of a survey led by the HVAC contractors association B&ES. “It is not uncommon”, says project leader David Frise, “for as much as 9 kW to be lost in transmission from a GSHP calculated to deliver 28 kW.” &nbs...
IPCC Forecasts Boom for Air Conditioning
The UN’s Intergovernmental Panel on Climate Change (IPCC) sees one of the positive aspects of global warming as an increasing role for air conditioning worldwide. Residential cooling, in particular for middle class households, will grow by 30 times the present level and the electrical load will have risen from 300 TWh to 10,000 TWh by 2100.

Cooling without Refrigerants
Most of the alternative methods of cooling that avoid the use of refrigerant fluids have been laboratory-based and of a relatively low yield in terms of cooling power. An overview of the kind of technologies involved and their current state of development is provided in a survey by Navigant Consulting commissioned by the U.S. Department of Energy. The survey identifies around 17 different p...

VRF in France
Sales of VRF systems in France increased to over 15,000 units in 2013, a 4% gain over the year before. Two thirds of the demand came from small-scale renovation projects involving units of less than 100 kW. The competition in this region is generally from multi-split systems although overall sales of these units in ratings of over 17.5 kW fell by 14% in 2013. Cassettes are the preferred for...
