Product Description


This series air source heat pumps are specially designed for cold climates and to work in outside air temperatures of -30°C. Its core philosophy is to solve the user‘s home heating requirements during winter and spring and provide cooling during a hot summer and autumn. High temperature EVI Scroll compressors are equipped with a vapour injection connection for Economizer Operation. Effective enhancement is accomplished by utilising a sub cooling circuit, it also increases heating capacity. The system is readily capable of reaching an outlet water temperature of 65°C

The refrigerant from the condenser is undercooled and then throttled, and then entered the evaporator to melt the frost layer on the evaporator. Compared with the commonly used reverse cycle defrosting, there are essential differences.

(1) Defrosting in the normal heating at the same time, does not affect heating and indoor load.

(2)It can better adapt to the defrosting requirements of fin heat exchanger in different environments and different parts, and do point-to-point accurate defrosting.

(3) Defrosting does not require any other energy, continuous constant heating efficiency.

(4) Set in the light frost, the frost will be removed, so that the unit in the frost-free state of operation.

Automatic scale removal and unique nitrogen bead antifreeze technology can effectively extend the high efficiency of heat exchanger service time and heat transfer efficiency.

Single chip microcomputer is a single chip microcontroller, chip integrated computer system, equivalent to a micro computer. Bo lang single chip microcomputer control system logic control careful, small volume, light weight, strong stability, can deal with various operating conditions and protection measures.

Adopt EVI air injection technology, double stage compression, improve heating efficiency, even under -25° C environment can be efficient operation.

Adopts American gold aluminum fin evaporator technology, precious metal nano double layer coating, defrosting more quickly. Effectively improve the evaporation efficiency of air and rain water, dust is not easy to accumulate, to ensure that -25℃ can also have a strong heat transfer.

Triple sound insulation and heat insulation

· The machine adopts triple sound insulation cotton, together with special shock absorbing pad, equipment foundation platform and customized fan, which can reduce the noise caused by operation vibration to below 55 dB.

· At the same time, it can effectively avoid the contact between the host and the outside low-temperature air, and protect the stable operation of the unit in the low-temperature environment.
