Simulation Results for an Air-Conditioning System With Secondary Refrigerant Loops
Heat Pump and Refrigeration Systems Design, Analysis, and Applications, 1995Abstract There are some highly efficient and environmentally safe hydrocarbons and HFCs proposed as R22 substitutes, but they are flammable. The use of these refrigerants in an air-conditioning/heat pump system may not be acceptable. The present research looks into the prospects of using an additional loop with a secondary refrigerant as

The Sound Attenuator – Secondary Source of Contamination in Air-Conditioning Systems?
International Journal of Ventilation, 2003AbstractThe problem of the hygienic state of air-conditioning installations in many countries is still treated with limited attention and, in general, this issue is disregarded both when systems are designed and when the maintenance of already operating system is performed. In order to highlight problems resulting from contamination of the installation,
