As a phenomenon in nature, just as water flows from a high place to a low place, heat always flows from a high temperature zone to a low temperature zone. But people can create machines, like pumps that lift water from a low point to a high place. Heat pumps can pump heat from low temperatures to high temperatures. Therefore, the heat pump is essentially a heat boosting device. The heat pump is used to extract heat from the surrounding environment and transfer it to the heated object (higher temperature object). The working principle is the same as that of the refrigerator. The reverse of the Carnot cycle works, the only difference is the operating temperature range. When the heat pump is working, it consumes a part of the energy itself, excavates the energy stored in the environmental medium, and uses the heat transfer working fluid circulation system to increase the temperature, and the whole heat pump device consumes only a small part of the output work. Therefore, the use of heat pump technology can save a lot of high-grade energy. In operation, the evaporator extracts heat from the surrounding environment to evaporate the heat transfer medium. The temperature and pressure of the working medium vapor are compressed by the compressor. When the high temperature vapor is condensed into a liquid through the condenser, the released heat is transferred to the storage. Water in the water tank. The condensed heat transfer medium is returned to the evaporator through the expansion valve and then evaporated, thus circulating back and forth. Water flows from a high point to a low place, and heat is transferred from a high temperature object to a low temperature object. This is a natural law. However, in real life, people use pumps to pump water from low to high for the needs of agricultural irrigation, domestic water, and so on. Similarly, in today's increasingly energy-intensive, heat pumps are used to transfer heat from low-temperature objects to high-temperature objects in order to recover heat from low-temperature hot gases that are normally discharged into the atmosphere, low-temperature hot water discharged into rivers, and the like. Objects to heat water or heating to make full use of heat. The basic principle of heat pump water heater: it is mainly composed of compressor, heat exchanger, axial flow fan, heat preservation water tank, water pump, liquid storage tank, filter, electronic expansion valve and electronic automatic controller. After the power is turned on, the axial fan starts to operate, the outdoor air exchanges heat through the evaporator, and the air after the temperature is lowered is exhausted by the fan. At the same time, the internal combustion fluid of the evaporator is sucked into the compressor, and the compressor will The low-pressure working gas is compressed into a high-temperature, high-pressure gas and sent to the condenser. The water forced to be circulated by the water pump also passes through the condenser, is heated by the working medium and sent to the user for use, and the working medium is cooled into a liquid, and the liquid is expanded. After the valve throttles to cool down, it flows into the evaporator again. After repeated cycles, the heat in the air is continuously “pumped†to the water, so that the temperature of the water in the insulated water tank gradually rises, and finally reaches about 55 °C, which is just suitable for people to take a bath. It is the basic working principle of air source heat pump water heater. The air source heat pump is one of the most advanced energy utilization products in the world today. With the rapid development of the economy and the improvement of people's living standards, domestic hot water has become a necessity for people's daily life. However, traditional water heaters (electric water heaters, fuel oil and gas water heaters) have disadvantages such as high energy consumption, high cost and serious pollution; The operation of energy-saving and environment-friendly solar water heaters is subject to meteorological conditions. The heating principle of the air source heat pump is completely different from that of the traditional solar water heater. The air source heat pump uses air, water, solar energy, etc. as the low temperature heat source, and the air source heat pump uses the electric energy as the power to extract heat from the low temperature side to heat the domestic water, and the hot water passes through the circulation. The system feeds directly to the user as a hot water supply or uses a fan coil for small area heating. Air source heat pump is the best solution for large, medium and small hot water centralized supply systems in school dormitory, hotel, bathing center and other places. A soap dispenser (in europe mostly known as soap squirter) is a device that, when manipulated or triggered appropriately, dispenses soap (usually in small) in the kitchen.
