Advanced Monitoring of R-22 Refrigerant Leakage

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...

Performance and Leakage Investigations of Refrigeration and Airconditioning Systems Using Refrigerant Mixtures as Working Fluids

In spite of the advantages of zeotropic refrigerant mixtur~" [1], the industrial >tpplications of mixtures have been very limited up to now. The major problem is seen iu the leakages occuring in refrigeration plants and so a possible change in composition. Another disadvantage is that no simple methods for determination of the concentratiou insick the t:ydc i\rc available. This paper pre$ents t...

Characteristics of Refrigerant and Oil Losses Due to a Leakage in Air Conditioning System

Possibility of a system leakage in an air-conditioning system always exists. Once a leakage occurs refrigerant and oil escape from the system and compressor. This paper determines the characteristics of the losses. Two important factors affecting the loss characteristics are location of leakage in the system and speed ofleakage or leakage rate. This paper then reasons the tested actual loss cha...

Theoretical Analysis of Hydrocarbon Refrigerant Mixtures as a Replacement for HCFC -22 for Residential Uses

This paper investigates the feasibility of hydrocarbon refrigerant mixtures as a replacement for HCFC-22 in residential air-conditioning and heat pump systems. The COP and the seasonal performance factor (SPF) were calculated using a UA-model for single component refrigerants and refrigerant mixtures. Simulations were run for pure propane and the mixtures of propane/i-pentane, propane/n-butane,...
