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 purpose of a refrigerator is the removal of heat, called the cooling load, from a low-temperature medium.
The Ideal Vapor‐Compression Refrigeration Cycle The vapor-compression refrigeration is the most widely used cycle for refrigerators, air-conditioners, and heat pumps. Fig. 5-2: Schematic for ideal vapor-compression refrigeration cycle. Assumptions for ideal vapor-compression cycle:
The refrigeration cycle explains to us what is happening to the ac freon in each of the four components within the air conditioner units. It tells us how much refrigerant the evaporator absorbs, the refrigerant properties in the compressor, and how much refrigerant the condenser rejects. Understanding the basic refrigeration cycle diagram also ...
Construct the simulation above described and determine the right flowrate in the cycle. Determine all temperatures and obtain the COP. Compare it with a Carnot Cycle. The above exercise can be done automatically using a “controller”, which is a type …
The ideal basic refrigeration cycle consists of four components, connected by piping with refrigerant flowing through the system. Figure 13 shows the components in the cycle
Introduce the concepts of refrigerators and heat pumps and the measure of their performance. Analyze the ideal vapor-compression refrigeration cycle. Analyze the actual vapor-compression refrigeration cycle. Review the factors involved in selecting the right refrigerant for an application.
Figure 2-8: TS and P-H diagram for liquid sub-cooling in a refrigeration cycle. Exercise 2-4: Implement the sub-cooling cycle in Pro II and report the new COP. Compare it with the dry cycle without sub-cooling and the Carnot cycle. Use streams E and F …
The real refrigeration cycle with its typical phase tran-sitions can also be represented in this T-s diagram. The cycle has many similarities to the familiar steam power cycle. The major difference is that the cycle is anticlockwise. Thus the processes of evaporation and condensation and expansion and compression (pump-ing) swap places.
