Vapour compression cycle is an improved type of air refrigeration cycle in which a suitable working substance, termed as refrigerant, is used. At this stage in the refrigeration cycle, high pressure liquid refrigerant will flow down the liquid line, through a filter drier that is designed to prevent contaminants from flowing through the system, and on to the metering device. Saturation curve this curve represents what state (vapor or liquid) and region (sub-cooled, latent heat, and superheat) the refrigerant is in. A refrigeration system is a combination of components and equipment connected in a sequential order to produce the refrigeration effect. Introduction A major application area of thermodynamics is refrigeration, which is the transfer of heat from a lower temperature region to a higher temperature one.
refrigeration cycle. Cycle with under cooling or sub cooling of refrigerant, Advantages of Vapour Compression System : It has a smaller size for the given capacity of refrigeration. Cycle with superheated vapor after compression, 4. Understanding the basic refrigeration cycle diagram also helps us to find subcooled, superheat and to troubleshoot refrigeration processes much easier. The refrigeration cycle can be broken down into the following stages (see Figure 4.2): 1 – 2 Low pressure liquid refrigerant in the evaporator absorbs heat from its surroundings, usually air, water or some other process liquid. Refrigeration and air conditioning.ppt - Free ebook download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. The evaporator or low pressure, in the "low side" and the condenser, or high pressure, in the "high side". Refrigeration cycle 4.
Refrigeration systems refer to the different physical components that make up the total refrigeration unit. Two different pressures exist in the refrigeration cycle. In this refrigeration cycle diagram, the air conditioner condenser is air cooled condenser. This course is … Cycle with superheated vapor before compression, and 5. These systems consist of an evaporator, a condenser, a compressor and an expansion valve. The condenser units are located outdoor with the compressor. Training Session on Refrigeration … Refrigeration cycle 1. Zubair Latif Comsats institute of information technology, Lahore 2. Academia.edu is a platform for academics to share research papers. Cycle with wet vapor after compression, 3. The evaporator or low pressure, in the "low side" and the condenser, or high pressure, in the "high side". These pressure areas are divided by the other two components. Basic Refrigeration Cycle Made by Engr. The PowerPoint PPT presentation: "Refrigeration Basics 101" is the property of its rightful owner.
It functions the same way as the evaporator but it does the opposite. The vapor-compression uses a circulating liquid refrigerant as the medium (usually R134a) which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere.The figure depicts a typical, single-stage vapor-compression system.The typical vapor-compression system consist of four components:
