Refrigeration thermodynamics
WebAug 18, 2024 · An air conditioner works using a thermodynamic cycle called the refrigeration cycle. It does this by changing the pressure and state of the refrigerant to absorb or release heat. The refrigerant (aka coolant) absorbs heat from inside of your home and then pumps it outside. Most air conditioners are air-source, split systems. WebThe vapor-compression refrigeration cycle is the most common cycle. This cycle requires the use of four main components, a compressor, a condenser, an expansion valve , and an evaporator. Refer to the figure below for a …

WebSep 12, 2024 · The effectiveness or coefficient of performance K R of a refrigerator is measured by the heat removed from the cold reservoir divided by the work done by the working substance cycle by cycle: (4.4.1) K R = Q c W = Q c Q h − Q c. Note that we have used the condition of energy conservation, W = Q h − Q c, in the final step of this expression. WebRefrigeration. The term refrigeration denotes cooling of a space, substance or system to lower and/or maintain its temperature below the ambient one (while the removed heat is rejected at a higher temperature).
