Performance Evaluation and Optimization of A Refrigerant Distributor for Air Conditioner

Evaluation of a Refrigerant R410A as Substitute for R22 in Window Air-conditioner

CFCs have been phased out, except for essential users, and HCFCs are to be eliminated by 2020, because of their ozone depletion potential. This generates a need for the investigation of zero ozone depletion potential (ODP) refrigerants or refrigerant blends. R410A is among newer brand of refrigerant blends, with zero ODP. The biggest difference to R22 is the pressure levels generated which are ...

Design and Experimentation of Roll Bond Evaporator for Room Air Conditioner with R-22 as Refrigerant

The world is looking towards producing products which consume less power without compromising on quality of life. The increase in use of refrigeration and air conditioning appliances are contributing to global warming. The world wide temperatures are shooting up at an increasing rate. This paper presents a design of roll bond evaporator as the heat exchanger to provide cooling in room air condi...

Seasonal Applicability of Refrigerant Release Technology in Room Air Conditioner

The refrigerant release technology relieves even eliminates the over-compression loss of scroll compressor by bypassing the refrigerant in the compression chamber to the suction pipe under small system pressure ratio conditions. Because the room air conditioner works in mild conditions at most of the time, its seasonal energy performance is expected to be effectively improved by the refrigerant...
