R32/R290 (68/32wt. %) is proposed to replace R410A in household air conditioners.The ODP of the mixed refrigerant is 0, and the GWP is 22.0% of that of R410A.The refrigerant charge amount is 30.0%–35.0% lower than that of R410A.Higher cooling and heating capacities and similar CO...
THERMODYNAMIC ANALYSIS OF HFC R152a REFRIGERANT AS AN ALTERNATIVE TO HFC R134aTheoretical COP of R152a is higher than the other refrigerants in consideration over the range of Evaporator temperature chosen. Hence it can work efficiently for both Refrigeration and Air Conditioning applications.Alok ...
etc.) have very highglobal warming potentials(GWP) on a per kg emitted basis. Energy scenarios for reduction of CO2emissions often include increased use of heat pumps substituting forfossil fuelheating systems. It has to be kept in mind that refrigerant emissions due to leakages counteract to a...
Ideal refrigerant properties, explanations of nomenclature, various types of refrigerant mixtures, ozone depletion factors and global warming impact are given, together with a worked example of a TEWI calculation. An explanation of ‘glide’ is illustrated using a p–H diagram. Excerpts from the ...
Knocking holes in buildings, digging upparking lots and disposal of the scrap can be eliminated whenyou can fit the equipment through the standard entrances.The oil used in the chiller is a waste material which is reducedby use of HFC-134a. HFC-134a lacking the chlorine elementdoes not use ...
In the refrigerant loop, the subcooled refrigerant R134a is pumped by a gear pump from a subcooler. Then the fluid passes through a flow meter and is heated by a pre-heater to control the vapor quality before the evaporators. After that, the two-phase R134a enters the two same sub-...
