According to the second law of thermodynamics, heat cannot spontaneously flow from a colder location to a hotter area; work is required to achieve this. An air conditioner requires work to cool a living space, moving heat from the interior being cooled (the heat source) to the outdoors (the heat sink). Similarly, a refrigerator moves heat from inside the cold icebox (the heat source) to the … WebJul 28, 2024 · A miniature steam ejector refrigeration system embedded with a capillary pump loop can result in a compact design which can be used for electronics cooling.

WebSep 15, 2024 · The Evaporator. The evaporator does the exact opposite of the condenser. Instead of turning the refrigerant from gas to liquid, it turns the refrigerant from liquid to gas (thus the name “evaporator”). Instead of expelling heat, it absorbs heat and turns the air cold around it. This is where the “conditioning” of the air occurs. WebThis paper presents a competitive cogeneration system, which combines the organic Rankine cycle with the heat pump cycle through a"built-in"evaporator. With this innovative structure, the input waste heat temperature in both the sub-cycles can simultaneously be maintained at a high level. The optimal working fluid is screened.
