Refrigerators and Heat Pumps wow po 61

Refrigerators and Heat PumpsRefrigerators and heat pumps are very similar to heat engines. They consist of a heat source, a heat sink, and a cycle between the two.A refrigerant enters a compressor as vapor, where it is (wow) compressed. It leaves the compressor at high pressure and temperature, and as it flows through a condensor wow gold, loses some of its heat to the outside (as waste in the case of a fridge, as heat to warm a house in the case of a heat pump) and begins to condense into liquid. The fluid then passes through a throttling valve, where the pressure and temperature drop dramatically. Finally, the low-temperature refrigerant enters an evaporator, where it evaporates by absorbing heat from the space to be refrigerated - in the case of a refrigerator, the fridge, or for a heat pump, the outdoors wow po. The heated vapor proceeds to the compressor, and the cycle begins again.The efficiency of a refrigerator or a heat pump is known as the coefficient of performance (COP) Acheter Des PO. In the case of a refrigerator, it is the ratio of the desired heat loss to the required work input; for a heat pump, it is the ratio of the desired heat output to the required work input.
