This application analyzes the following refrigeration cycle, and calculates the coefficient of performance.


Vapour cycles can be subdivided into vapour compression systems, vapour absorption systems, vapour jet systems etc. Among these the vapour compression refrigeration systems are predominant.


1 Thermodynamic cycles. 1.1 Vapor-compression cycle.


The Vapor-Compression Refrigeration Cycle. ► Applying mass and energy rate balances.


5. Ammonia-absorption refrigeration cycle requires (a) very little work input (b) maximum work input (c) nearly same work input as for vapour compression cycle (d) zero work input (e) none of the above.


Compressor-map equations correlate compressor performance at a certain suction superheat and condenser subcooling.


Chapter 10: Refrigeration Cycles The vapor compression refrigeration cycle is a common method for transferring heat from a low temperature to a high temperature. The above figure shows the objectives of refrigerators and heat pumps.


The reversed Carnot cycle is not a suitable model for refrigeration cycle! • Process 2 – 3 involves the compression of a liquid-vapor mixture, which requires a compressor that will handle two phase.


Therefore, equations pertaining to steady-flow systems should be used in the analysis of the Rankine cycle
