Heat Pump Air Conditioner

Heat Pump Air Conditioneris equipped with a self-developed NB-iot Internet of Things remote intelligent control module. It can be operated via a mobile phone APP, eliminating the need for dedicated personnel to stand by. It offers fault early warning prompts and online diagnosis. It can operate efficiently in an ambient temperature range of -30℃ to 43℃, with a maximum water outlet temperature of 60℃. It has various terminal forms and is suitable for radiator, floor radiant, central air conditioning cooling and heating. The national patented intelligent defrosting technology accurately detects frost, quickly defrosts, significantly reduces the frequency of defrosting, and greatly shortens the defrosting time. In addition, this unit also has unique advantages such as modular customization, no need to build a machine room, environmental protection and energy conservation, high efficiency and low noise, and wide application range.

Heat Pump Air Conditioner The GRAD air source heat pump unit adopts a modular design. The entire unit system is easy to expand and can be combined with 16 modules. The maximum capacity of the system can reach 2080 KW. It can be customized according to industrial process conditions to achieve year-round cooling or heating, meeting the needs of different processes.

Low ambient temperature air source heat pump/chiller

● Adopt the internationally leading EVI air jet high-efficiency compressor with turbine direct injection enthalpy, quasi-two-stage compression, the medium pressure gas supplement, increase the suction capacity of the compressor, improve the heating efficiency.

● The main valve and auxiliary valve are all intelligently and accurately adjusted by electronic expansion valve, and the refrigerant flow control is more accurate, improving the reliability and heat transfer efficiency of the unit.

● It can operate stably at -30℃ temperature, and is an ideal product for replacing boilers for heating in northern winter.
