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 ...
متن کاملTesting of Environment Friendly Refrigerant R290 for Water Cooler Application (RESEARCH NOTE)
This paper presents environment friendly refrigerant R290 as a solution to the environmental concerns like depletion of ozone layer and rise in global warming because of wide use of synthetic refrigerants R22 and R134a. The water cooler is the widely used refrigeration application in warm climatic countries. Refrigerant R22 and R134a are predominantly used refrigerants in water cooler refrigera...
متن کاملCycle Performance and Heat Transfer Characteristics of a Heat Pump Using R22/R142b Refrigerant Mixtures
A heat pump system is constructed tO evaluate the performance and the heat transfer characteristics. Mixtures of R22/Rl42b are adopted in the heat pump. The heat transfer in the evaporator and the overall perfomance arc measured and analyzed in terms of the compositions and the flow rate of the refrigerants. The evaporator consists of counter~currem concentric circular tubes. Possibility of cap...
متن کاملReplacing dairy milk with soy
Many people drink dairy milk (from a cow) as a healthy source of calcium and protein. In every eight-ounce cup of dairy milk, there are eight grams of protein and twelve grams of carbohydrates. It?s also rich in other nutrients as well: one cup provides adults with about 30 percent of their daily calcium needs and about 50 percent of their vitamin B12 and riboflavin requirements. Despite these ...
