Characteristics of Air Source Heat Pump
1. The air source heat pump system integrates cold and heat sources. No special refrigerator room or boiler room is required. The unit can be placed on the roof or ground at will, without occupying the effective use area of the building. The construction and installation are very simple.
2. The air source heat pump system has no cooling water system, no cooling water consumption, and no cooling water system power consumption. In addition, legionella infection caused by cooling water pollution has been reported in many cases. From the perspective of safety and health, considering the air source heat pump also has obvious advantages.
3. The air source heat pump system is safe, reliable and pollution-free because it does not require boilers, corresponding boiler fuel supply systems, dust removal systems and flue gas emission systems.
4. The air source heat pump cooling (heating) water unit adopts the modular design, without the need for a standby unit. During the operation, the computer automatically controls the operation of the unit to adjust the operating state of the unit, so that the output power can adapt to the working environment.
5. The performance of air source heat pump will change with the change of outdoor climate.
Application Scope of Air Source Heat Pump
1. For regions with hot summer and cold winter: the climate of regions with hot summer and cold winter is sultry in summer. The average regional temperature in July is 25-30 ℃, and the number of days with annual average daily temperature greater than 25 ℃ is 40-100 days; It is wet and cold in winter. The average temperature in January is 0-10 ℃, and the number of days with annual average temperature less than 5 ℃ is 0-90 days. The daily range of temperature is small, the annual rainfall is large, and the sunshine is small. The climate characteristics of these regions are very suitable for the application of air source heat pumps
2. In some areas, the average temperature in January is 1-13 ℃, and the number of days with annual average daily temperature less than 5 ℃ is 0-90 days. Under such climatic conditions, heating equipment was not provided for general buildings in the past. However, in recent years, with the development of modern buildings and the progress towards a well-off living standard, people have increasingly high requirements for the living and working building environment. Therefore, modern buildings and high-end apartments in these areas have also begun to set up heating systems. Therefore, in this climate condition, the air source heat pump system is very suitable
3. Traditional air source heat pump units can operate safely and reliably when the outdoor air temperature is higher than - 3 ℃. The temperature in winter is low, and the average temperature in January is - 10-0 ℃. However, during the heating period, the number of hours when the temperature is higher than - 3 ℃ accounts for a large proportion, while the time when the temperature is lower than - 3 ℃ mostly occurs at night. Therefore, the air source heat pump is selected for the buildings mainly operating in the daytime in these areas (such as office buildings, shopping malls, banks and other buildings), and its operation is feasible and reliable. In addition, the climate in these areas is dry in winter, and the outdoor relative humidity in the coldest month is about 45% - 65%. Therefore, the frost phenomenon is not too serious when using air source heat pumps.

FAQ of air source heat pump
1. What kind of equipment is air source heat pump?
This device is a high-tech energy-saving equipment for hot water production. It absorbs heat from the air and heats the water to a maximum temperature of 65 ℃. As a central hot water equipment, it is widely used in hotels, hotels, sauna centers, hospitals, factories, residential areas and other integrated water use units and small water use units such as villas, families, beauty salons, etc.
2. Is the air source heat pump easy to damage?
The air source heat pump itself is equipped with various protection facilities, such as overload, overheating, phase loss, overpressure, snow shortage protection, etc., so you don't need to worry about its damage. Its operation and life of the whole machine are equivalent to that of the air conditioner.
3. Is the operation and maintenance of air source heat pump easy to master?
The air source heat pump is close to the air conditioner, so as long as the personnel who can repair the air conditioning equipment refer to the equipment manual, they can maintain the air source heat pump. Ordinary electricians can go on duty as long as they receive simple training. Of course, this is only for some large units that need to adjust the unit frequently according to the amount of water used. However, domestic air source heat pumps do not need to worry about maintenance, because they are fully automatic and stable, and do not need to be adjusted frequently.
