Six technical questions and answers for air energy heat pump units

Air energy heat pumps have been developed in my country for more than ten years. Because of various advantages such as high efficiency, energy saving, safety and reliability, environmental protection, and pollution-free, it has become the main force of “coal-to-electricity” and has attracted the attention of many parties. The following is a compilation of the six major issues that everyone is concerned about and ask air experts to give professional answers.

1. Can the heat pump unit operate normally when the temperature is low in winter?

can. The air energy heat pump unit has an intelligent defrosting function to ensure the stable operation of the unit in a low-temperature environment. It can automatically enter and exit the heat pump according to multiple parameters such as outdoor ambient temperature, evaporator fin temperature and unit running time, and intelligent judgment.

2. Is it necessary to charge the refrigerant frequently?

unnecessary. The air source heat pump unit is a sealed part like a refrigerator, and the refrigerant has been filled in a certain amount when it is delivered to the user, and the user does not need to charge it by himself during use.

3. Is it necessary to provide a computer room?

No, the heat pump unit can be placed anywhere you specify, without affecting the beauty of the building, requires little space, does not require direct sunlight, and is very easy to install. It can be placed in the open air, or placed in an inconspicuous corner, or in the basement In, and can realize unmanned operation, and automatic control of a constant temperature water supply.

4. If multiple heat pumps are used, will a problem with one of them affect the entire system?

does not affect. The air energy heat pump unit has a modular function and adopts grid-connected operation. Each heat pump unit can be controlled separately. Even if one of them has a problem, it will not affect the normal operation of other units during maintenance.

5. How to match the water tank of each type of heat pump?

Because the output load of the heat pump unit is relatively small and the speed of hot water production is slow, the heat pump unit first prepares hot water for use at any time, instead of producing hot water when the water is used. The water tank is designed according to the user’s daily water consumption, and the design capacity is large enough. It can realize 24 hours continuous water supply.

6. How to choose the water tank of the household heat pump water heater?

The water tank of the heat pump water heater is determined according to the actual water consumption of the user in a day. Under the acceptable conditions of the user, it is recommended that the user choose a water tank of a larger size. For a general family: 1-2 people, with a 150 or 200L water tank (100L/person); 3 -4 people, with 200 or 2×150L water tanks (80L/person); 5-6 people, with 300 or 2×200L water tanks (70L/person).
