Mar 12, 2025 · Understanding the refrigeration cycle diagram and process equips you with essential knowledge about how various cooling systems work, from household refrigerators to industrial cooling solutions. The Refrigeration Cycle There are four main components in a refrigeration system: • The CompressorThe Compressor • The Condensing Coil • The Metering Device • The Evaporator • Two different pressures exist in the refrigeration cycle. See the diagram and examples of the vapor compression cycle, the main type of refrigeration cycle used in air conditioners and HVAC systems. Compressor: Jun 25, 2003 · Mechanical refrigeration is accomplished by continuously circulating, evaporating, and condensing a fixed supply of refrigerant in a closed system. The evaporator or low pressure, in theor low pressure, in the "low sidelow side" and the condenser, or The T-s diagram for a vapor-compression refrigeration cycle is shown below. Introduction to Vapour Compression System: For a closed cycle of refrigeration employing the condensable refrigerant vapour, the following processes are required: (i) Compression of the vapour, thereby increasing pressure. Fig. 9. The most widely used refrigeration cycle is the vapor-compression refrigeration cycle. Figure 5: P-H diagram representation of a dry refrigeration cycle The refrigeration cycle involves four main components: the compressor, the condenser, the expansion valve or capillary, and the evaporator, all of which manipulate the pressure and phase (liquid or gas) of the refrigerant to absorb heat inside the compartment and release it outside the compartment. The refrigeration cycles can also be represented in a P-H diagram. An AC refrigeration cycle diagram is a visual representation of the different components that make up an air conditioning system and how they interact to provide cooling. Components of an AC Refrigeration Cycle Diagram. It consists of four main processes: (1) compression of refrigerant vapor in a compressor, (2) condensation of the high-pressure vapor into a liquid in a condenser, (3) expansion of the high-pressure liquid through a throttling valve or expansion device, and (4) evaporation of the low-pressure liquid in an evaporator. Cascade cycle is used where a very wide range of temperature between TL and TH is Figure 4: Wet refrigeration Cycle - The expander has been substituted by a throttling valve. These components may be in difference shape, capacity and size, but it does the same thing. . Understanding the various components in the diagram is essential for troubleshooting and maintaining an AC system.
