Vapour Absorption Refrigeration System (with diagram)! The power utilized in vapour compression system is high grade energy i.e., electric power for running the compressor motor. In absorption refrigeration system, however, heat is directly utilized as source of energy. Of course, it may be preferable to utilize heat as such as it avoids undergoing through the various energy transformations required in [...]
Vapor compression refrigeration system consists of the following important components: 1. Compressor 2. Condenser 3. Receiver 4. Expansion Device 5. Evaporator. Vapor compression refrigeration system is the most popular and universally used system for the production of low temperature. In this system a working fluid known as refrigerant (such as Freon-12, Freon-22, NH3, SO2, CO2, etc.) is used. It condenses [...]
In this article we will discuss about:- 1. Meaning and Applications of Refrigeration 2. Principle of Refrigeration 3. Unit 4. Effect 5. Types. Meaning and Applications of Refrigeration: Refrigeration is the process of removing heat continuously from the system to be cooled to maintain the temperature lower than the atmospheric temperature. i. Food Preservation - Milk storage, butter storage, dairy [...]
In this article will discuss about the components, merits and demerits of air cycle refrigeration system. Components of Air Cycle Refrigeration System: The air cycle refrigeration system uses air as working fluid/refrigerant. This system is working on reversed Brayton cycle. Figure 6.18 shows a simple diagram of an air cycle refrigeration system known as Bell-Coleman cycle. Following are the components [...]
