WebNov 11, 2010 · The COP excluding the pump work and the generator energy required is as high as 5.4–6.2, which is higher than that of the single vapor compression cycle and absorption cycle, under the same operating conditions (evaporation temperature at 263 K and condensation temperature at 308 K). WebApr 4, 2024 · A Vapour compression cycle is generally known as VCC is a refrigeration cycle. In this cycle, the refrigerant is sealed condition in an airtight mechanism and is compressed in a compressor which permits the transfer of heat energy. The refrigerant absorbs heat from one place and releases it to another place.
