What is the difference between air source heat pump compressor and air conditioning compressor? Just look at it

With the development of air source heat pump industry, air source heat pump has gradually entered the public's field of vision However, many people still lack of understanding of air source heat pump They often ask about the difference between air source heat pump and air conditioning There is still a big difference between them The compressor of air energy water heater, such as human heart, plays an important role The performance and reliability of air energy water heater mostly come from the guarantee of compressor Only the compressor with excellent quality can maintain the good operation of the heat pump, realize heating and ensure the service life of the heat pump What's the difference between a heat pump compressor and an air conditioning compressor? 1 As a summer refrigeration product, air conditioning usually has a high frequency of use in summer, but the water heater is a daily necessities needed in all seasons of the year In winter, because of the low temperature, the demand for hot water is greater, it needs to run for a long time, and the running time is much longer than air conditioning The long-term operation of compressor will affect the service life of air energy water heater 2 When the air conditioner is hot in summer, the condensation temperature can reach the Zui value allowed by the compressor However, the water temperature of air energy heat pump is generally above 55 ℃ Once the water temperature drops to a certain value, the compressor needs to be started, so the compressor basically runs in the area with high condensation temperature If compared with the air conditioning load, the air energy water heater is "overloaded" all the year round The condensing temperature will affect the service life of the compressor The compressor in the air source heat pump water heater must bear higher load than the compressor in the air conditioner 3 Under the influence of the coal to electricity policy, air source heat pump is widely used in the northern market In order to meet the needs of heating in winter, cooling in summer and domestic hot water, and to operate in ultra-low temperature environment, special heat pump compressor is required The special compressor for heat pump can operate in the ultra-low temperature environment of - 25 ℃, and the heating capacity at low temperature is increased by 100% The performance of air-conditioning compressor starts to decline below 0 ℃ Although it can be started to a certain extent, the defrosting time is very long, and it has no effect when it is turned on, and the power consumption is very high 4 When the common air-conditioning compressor is operating at high compression ratio, the motor is easy to overheat, and the special compressor for heat pump can solve this problem Under the condition of high compression ratio, the special compressor for heat pump can still operate reliably to ensure normal operation 5 When the air conditioner is cooling, the evaporator is in the room and the air temperature is controlled at 25 ° Zui, which determines that the temperature of the air conditioner evaporator is not too high The evaporation temperature of air source heat pump water heater is the atmospheric temperature, which may be much higher than the air conditioning in summer High temperature flow, which is another important factor of air water heater compressor overload Combined with the above factors, it can be seen that the air source heat pump water heater needs long-term stable operation and strong heating, so it is very necessary to use the heat pump compressor Therefore, consumers in the choice of air source heat pump water heater, or to recognize the special compressor heat pump.
