As a natural phenomenon, just as water flows from high to low, heat always flows from high temperature areas to low temperature areas. But people can create machines that can pump heat from low to high temperatures, just as water pumps are used to lift water from low to high. So the heat pump is essentially a heat-raising device. The function of the heat pump is to absorb heat from the surrounding environment and transfer it to the object to be heated (an object with a higher temperature). Its working principle is the same as that of a refrigerator. The reverse Carnot cycle works, the only difference is that the operating temperature range is different. When the heat pump is working, it consumes part of its energy and converts the energy stored in the environmental medium into
It can be excavated and used to increase the temperature through the heat transfer working fluid circulation system, and the work consumed by the entire heat pump device is only a small part of the output power. Therefore, the use of heat pump technology can save a lot of high-grade energy. During operation, the evaporator absorbs heat from the surrounding environment to evaporate the heat transfer medium. After the working medium vapor is compressed by the compressor, the temperature and pressure rise. When the high-temperature vapor is condensed into liquid through the condenser, the heat released is transferred to the storage medium. Water in the tank. The condensed heat transfer fluid returns to the evaporator through the expansion valve, and is evaporated again, and the cycle repeats.
