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...
متن کاملExperimental Investigation of Evaporative Heat Transfer Characteristics for R-22 and R-407C Using Thermochromic Liquid Crystal
Evaporative heat transfer coefficients of R~22 and R-407C (R-32/125/134a, 23/25/52 wt%) in a horizontal smooth tube have been measured. Heat was transferred to theJefrigerant at the test section by applying electric current directly to the stainless steel tube. Saturation temperature of refrigerant was calculated from the measured pressure. The inner wall temperatures were calculated by one dim...
متن کاملComparison of R-407C AND R-410A with R-22 in a 10
The performance of two long term replacements R-407C (HFC-32/125/134a (23%/25%/52%)) and R-410A (HFC-32/125 (50%/50%)) was compared to R-22 in a 10.5 kW (3.0 TR) residential central heat pump. The performance evaluations were carried out in a psychrometric calorimeter test facility located at NRC using the Canadian Standards Association (GSA) I Air-Conditioning and Refrigeration Institute (ARI)...

The system design of window air conditioner does not evolve in one day. Due to the continous efforts are taken by the refrigeration and air conditionging professionals, successful and economic models of window air conditioners are currently used. This paper states about the development of window air conditioner with phase change material and water as refrigerants. Developed air conditioner was ...
متن کاملAn Experimental Study of Nanofluids Operated Shell and Tube Heat Exchanger with Air Bubble Injection
Shell and Tube heat exchangers are the heat exchangers that are most widely used in industries and for other commercial purposes. There are many techniques that have been utilized to enhance the heat transfer performance of the shell and tube heat exchangers. Air bubble injection is one of the promising and inexpensive techniques that can create turbulence in the fluids resulting in to enhancem...
