1. when the temperature is low in winter, can the heat pump unit operate normally?
Yes. Air energy heat pump unit has intelligent defrosting function to ensure stable operation of the unit in low temperature environment. It can automatically enter and exit the tank according to multiple parameters such as outdoor environment temperature, evaporator fin temperature and unit operation time.
2. What are the advantages of air energy heat pump compared with conventional solar energy?
The advantages are obvious, mainly reflected in four aspects:
A. From the aspect of investment: if the same water supply effect is achieved, the investment in heat pump hot water unit is less than that in conventional solar energy products, and economic electric energy can be used to make hot water reserve when the electricity consumption is low.
B. From the aspect of use: the conventional solar energy products are obviously affected by the weather, and they can not work in rainy days, snowy days and at night, while the heat pump water heater can work as usual no matter in rainy days, rainy days, snowy days, at night or sunny days, providing hot water all day.
C. From the aspect of operation cost: conventional solar energy operates at almost zero cost under direct sunlight, but it can only rely on the auxiliary system to work in rainy and snowy days or at night. The statistical data shows that in normal use, the annual power consumption of conventional solar auxiliary system is higher than that of heat pump unit.
D. Other functions: the use of the heat pump unit is not limited by the location, it can be placed anywhere, and the floor space is very small, while the conventional solar energy needs to occupy a large space to achieve the same heating effect, and it must be placed in the open air; the heat pump unit can produce cold air while producing hot water, which can be used for dehumidification, cooling, air filtration and other auxiliary functions.
3. is it necessary to charge refrigerant frequently?
Unwanted. The air energy heat pump unit is a sealed part like the refrigerator. When it is delivered to the user for use, it has been filled with refrigerant according to the quantity, and the user does not need to fill it by himself during the use.
