Refrigeration and Air-Conditioning

A Review on Developments of Thermoelectric Refrigeration and Air Conditioning Systems: a Novel Potential Green Refrigeration and Air Conditioning Technology

In recent years, with the increase awareness towards environmental degradation due to the production, use and disposal of ChloroFluoro Carbons (CFCs) and Hydro Chlorofluorocarbons (HCFCs) as heat carrier fluids in conventional refrigeration and air conditioning systems has become a subject of great concern and resulted in extensive research into development of novel refrigeration and space cond...

Twin Screws of the Future for Air Conditioning and Refrigeration

SCREW COMPRESSORS IN REFRIGERATION AND AIR CONDITIONING Professor

Recent advances in the techniques of manufacture of vital parts, such as rotors and bearings, have enabled improvements to be made to screw compressors, which were difficult to imagine only a few years ago. This has inevitably influenced the prospects for these machines in refrigeration and air conditioning applications. Some aspects of this are presented, together with well known but not alway...

American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE)

In a historic building with inadequate or no air conditioning or where it is not possible to install modern systems fitted with air filters, humidification, and controls, it is possible to mitigate the effects of temperature and humidity extremes on a building and its contents by controlling air-flow. When used in conjunction with mechanical air conditioning, this method can also save a little ...

A Transcritical Refrigeration Cycle with Carbon Dioxide for Bus Air Conditioning and Transport Refrigeration

The frrst part of this paper presents carbon dioxide air conditioning units which were installed in two city buses. The two buses were tested "on-the-road" during summer 1997 in Bad Hersfeld, Germany. By the end of 1997, the air condition systems of the two buses had been running together for more than 860 hours proving that C02 systems fulfill important on-the-road requirements. In the second ...
