If this is cooling water, then the TH needs to be around 10 oC higher than the available cooling water temperature. The next table shows the existing refrigerants. It is followed by the boiling
The 6 Main Components of a Refrigeration System. Thermostatic Expansion Valve (TXV) Before the evaporator, this is located at the end of the liquid line. TXV is a device that controls the amount of refrigerant that flows to the evaporator. There you will find the floodback that is essential to maximise the productivity of the evaporator, while stopping the extra liquid refrigerant from going

Discuss the importance of selection of suitable refrigerant in a refrigeration system (Section 26.1) 2. Classify refrigerants into primary and secondary, and discuss the important differences between primary and secondary refrigerants (Section 26.2) 3. Discuss refrigerant selection criteria based on thermodynamic, thermophysical, environmental and economic properties (Section 26.3) 4. Describe
Refrigeration System Types Overview of CO 2 Systems A refrigeration system using carbon dioxide (CO 2) as a refrigerant is similar in nature to a refrigeration system using HFC refrigerants. A key difference is that CO 2 operates at higher pressures. In general there are two categories of refrigeration systems— non-cascade and cascade. The table below (Figure 4) summarizes suitability of
This principle is used in gas refrigeration system. In this system instead of using Freon or ammonia as the refrigerant, the gas is used as the refrigerant. Throughout the cycle there are no phase changes of the gas, which are observed in the liquid refrigerants.
Ship refrigeration systems play a vital part on ships carrying refrigerated cargo and victuals for the crew or passengers. Refrigeration prevents any damage to the cargo or decay of perishable foods, like growth of micro-organisms, oxidation, fermentation and drying out of cargo.
Commercial Refrigeration and Food Retail applications are very diverse regarding systems types and refrigerants used. It includes cold rooms, glass door merchandizers, and display and islands cabinets, either in centralized or plug-ins – hermetic or autonomous cooling circuits with condensing units.
