NettetPrimary refrigerants are those fluids, which are used directly as working fluids, for example in vapor compression and vapor absorption refrigeration systems. 1) Primary Refrigerant. 2) Secondary Refrigerant. Primary Refrigerant:-The refrigerant which takes part in the refrigeration cycle is known as the primary refrigerant. Nettet2. feb. 2011 · Mechanical refrigeration processes, of which the vapor compression cycle is an example, belong to the general class of reversed heat engine cycles, Figure 1.This figure represents, schematically, the extraction of heat at rate from a cold body at temperature T C.The process requires the expenditure of work W and the sum is … NettetEach stage operates on an ideal vapor-compression refrigeration cycle with refrigerant R-134a as working fluid. Heat rejection from the lower cycle to the upper cycle takes place in an adiabatic counter flow heat exchanger where both streams enter at about 0.32 MPa. If the mass flow rate of the refrigerant through the upper cycle is 0.05 cpoa promotional code
