Central air-conditioning originated from the refrigeration demand. Although the cooling and heating functions are taken into account, the heating function is relatively limited under low temperature conditions. Some models also need to rely on electric auxiliary heating in the low-temperature environment. The air source heat pump meets the standard refrigeration function of the central air conditioner, and the heating operation is also strong. After the technology upgrade, the temperature range of the low temperature air source heat pump heating operation environment can break the challenge of low temperature -25 °C.

In addition to meeting the refrigeration demand, the air source heat pump must also meet the heating requirements in a low temperature environment. Compared with the central air conditioner, it is required to configure a higher standard heat pump compressor. The difference between the compressors is the largest of the air source heat pump and air conditioner. the difference. The heat exchanger of the heat pump unit is optimized by design, and the heat exchange and defrosting effects are more efficient. On the whole, after the components are upgraded, the air source heat pump unit has a wider operating range, and the heating effect and the hot water temperature are higher. In particular, the low temperature air source heat pump design working environment temperature range can reach -25 ° C ~ 43 ° C.

There is a big difference between the air source heat pump and the fluorine machine in the connection. When the fluorine machine is running, the refrigerant directly exchanges heat with the air. The dehumidification amount is large, and excessive dehumidification may cause the indoor air to dry, and the feeling of opening for a long time is obvious. The air source heat pump is different from the fluorine machine in operation. After the outdoor unit compresses the refrigerant, the cold/hot water generated by the heat exchange with the water exchanges heat with the indoor air, the moisture in the air is not easily lost, and the air is softer. The human body feels more natural and comfortable.

The air source heat pump system is multi-purpose, the summer air disk is cooled, the winter linkage heating end supplies heat to the room, and supports various end forms including floor heating, wind disk and radiator to provide users with more comfortable heating effect and diversity. Choose a space.

Conventional central air conditioners have low hot water temperatures for heating, and low temperature heating effects are poor, resulting in limited choice of indoor ends. The air source heat pump unit has a higher water outlet temperature, and supports a variety of end modes for heating indoors during heating and heating, such as radiant floor, radiator, and special wind tray for heating.

The air source heat pump unit has high heat production efficiency and uses a small amount of electric drive compressor to operate. In winter, the general thermal efficiency (energy efficiency ratio) can reach 2.5-3.0. Compared with the use of wall-hung boiler heating and electric heating, the air source heat pump is more energy-efficient. it is good. The two sources of air supply are also one of the most energy efficient ways of heating.

The air source heat pump is a two-unit supply unit that effectively solves the cooling and heating needs, is energy efficient and environmentally friendly, and is a standard configuration for healthy and comfortable residences.
