Energy Conversion For Heat Pumps

As a phenomenon in nature, just as water flows from a high place to a low place, heat always flows from a high temperature area to a low temperature area. But people can create machines, just like water pumps are used to lift water from low to high, and heat pumps can be used to pump heat from low temperature to high temperature. Therefore, 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 heated object (object with higher temperature). Its working principle is the same as that of the refrigerator. The reverse Carnot cycle works, the only difference is the working temperature range is not the same. When the heat pump is working, it consumes part of the energy itself and converts the energy stored in the environmental medium
It is excavated and used by increasing the temperature through the heat transfer working medium circulation system, and the work consumed by the entire heat pump device is only a small part of the output work. 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 working medium. The temperature and pressure of the working medium steam rise after being compressed by the compressor. When the high-temperature steam condenses into liquid through the condenser, the heat released is transferred to the storage tank. water in the tank. The condensed heat transfer fluid returns to the evaporator through the expansion valve, and then evaporates, and so on.
