The heat pump water heater needs to use a special compressor

with the rapid growth of the domestic air energy water heater (heat pump water heater) market, the previous model of "external machine structure design of air conditioning" will be gradually broken. Since the launch of special compressor for heat pump in 2009, many domestic compressor manufacturers have invested in the development of special compressor for heat pump in order to provide core guarantee for the healthy development of heat pump water heater

according to experts, there is a great difference between the operation mode of heat pump water heater and air conditioner, which determines that there is a difference in the design concept between the special compressor for heat pump and the microcomputer controlled compressor for air conditioner. Compared with air conditioning, there is a great difference in the running time between heat pump water heater and air conditioning. The running time of heat pump water heater system is much higher than that of air conditioning. The operation time of heat pump water heater depends on the following factors:

air conditioners are used frequently in summer, but water heaters are daily necessities, and the operation time in winter is particularly long. The heating time of a tank of water in winter is several times that in summer, so it is necessary to confirm the operation mode of the heat pump water heater in winter. According to statistical calculation, 2/3 of the service life of the heat pump water heater is consumed in winter. If conditions permit, it can be equipped with cardboard compression tester and carton compression machine

because the outlet water temperature of the heat pump is above 55 ℃, the temperature of the water tank will drop with the use. When it drops to about 45 ℃, the compressor needs to start running. Therefore, the compressor basically operates in the area with high condensation temperature. The condensation temperature is the main factor affecting the service life of the compressor. Under the condition of running for the same time, the comprehensive load of the compressor in the heat pump water heater is much higher than that in the air conditioner

the main driving force for consumers to buy heat pump water heaters is energy conservation and convenience, which will lead consumers to 9 The lower fixture uses more water for the oil box, which also increases the working time of the heat pump

if the heat pump water heater is used for heating + domestic hot water, it may operate for a long time in the whole heating season

based on the above factors, it can be seen that the main engine of heat pump water heater will develop to miniaturization, and the actual operation time will increase significantly. In order to ensure that there is no failure in the life cycle of the heat pump water heater, the pressure 3. The passive needle cannot stop at random. The compressor needs to be able to withstand 20000 hours of actual operation. Therefore, it is very necessary to use a special compressor for the heat pump. With the rapid growth of the domestic heat pump water heater market, the previous model of "external structure design of air conditioner" will be gradually broken
