Question 1: Air to water heat pump used to work with electricity. Why we are not choosing the electric heating instead of heat pump? Why spend so much money?
Answer: Although we need to use electricity, the essence is different. Electric heating is directly operated by electricity, and its utilization efficiency is very low. Only three minutes of coal can produce one minute of heat. The efficiency of electric heating conversion is less than 40%, which means that about 60% of energy is wasted in electric heating conversion.
However, air source heat pump uses electric energy to transport the heat absorbed from the air. The working efficiency is much higher. The maximum heating energy efficiency can reach 4.0, and it is clean and pollution-free.

Question 2: Does low ambient temp heat pump can work in northern chilly area?
Answer: Let’s talk about why low ambient temp air source heat pump can operate normally at lower ambient temp. It is correspondingly solves several problems encountered by ordinary air source heat pump: insufficient heat generation, low COP and unstable operation due to low evaporation temperature, low suction flow rate, high compression ratio, high exhaust temp.
To solve these problems, the design structure of low ambient temp heat pump has been optimized, such like the scroll profile will be designed larger and the compression ratio will be increased. In addition, the use of jet enthalpy increasing technology, when the evaporation temperature is particularly low, through the introduction of external refrigerants, expand the temperature difference between the heat transfer and the environment temp, enhance the heat production.
In this way, due the lower evaporation temp and the higher heating capacity at the lower evaporation temp, the low ambient temp heat pump can also operate stably and reliably in the lower northern region, and the COP is relatively high.
