1. Working temperature & electricity charge
As anyone who has ever turned on air conditioning knows, turning on air conditioning in winter not only has poor heating effect, but also costs electricity. Don't complain. Actually, you can see the parameters of the air conditioner, which is related to the working temperature of the air conditioner.
Generally, the working temperature of the air conditioner is - 7 °C ~ 43 °C, that is to say, the air conditioner cannot work when it is lower than - 7 °C. However, in fact, when the air temperature is 0 °C, it is very difficult for the air conditioner to make heat, so most air conditioners will use electric auxiliary heating at this time. Generally, there are electric auxiliary function keys on the air conditioner remote controller. Therefore, when the air conditioner is heating in winter, the electricity consumption is very high.
As for the air energy heat pump, its working temperature is - 25 °C ~ 43 °C, and the air jet enthalpy increasing technology is adopted, which can withstand the cold outdoor test in winter. In addition, the air energy heat pump uses the energy in the air to produce heat, rather than simply relying on the "electricity heat" conversion mode, so the heat generation rate is as high as 400%.
Therefore, the air energy heat pump has a wider range of applications. In winter heating in the north, not only the heating effect is better than air conditioning, but also more energy-saving.
2. Unit design
(1) compressor: the built-in compressor of air energy heat pump is a jet enthalpy increasing compressor with good low-temperature heating performance;
(2) different system pressure: the pressure of air energy heat pump is much higher than that of air conditioner, so the copper pipe of air energy heat pump is thicker than that of air conditioner;
(3) maximum bearing temperature: Generally speaking, the maximum temperature borne by the air conditioning unit itself is not more than 40 ℃, while the air energy heat pump can reach 60 ℃; (4) service life: Generally speaking, the service life of the air conditioning is 7-8 years, and the service life of the air energy heat pump can reach more than 15 years. According to the sex price ratio, it is more cost-effective to buy air.
