Prediction Using Equivalent Ratio in Estimating of the Performance of Heat Pump Air Conditioner

Impacts of Refrigerant Charge on Air Conditioner and Heat Pump Performance

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...

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...
