High Efficiency Air Cooled Screw Chiller Heat Pump
Air-cooled screw type cold (hot) water unit is based on air as a cold (hot) source, water as a refrigerant, it can be cooling and heating, and can run all year round, with environmental protection, energy saving, comfortable, stable characteristics.
The GRAD Air source heat pump unit is equipped with a self-developed NB-iot Internet of Things remote intelligent control module. It can be operated via a mobile phone APP and does not require dedicated personnel to stand by. It also features fault prediction Warning alerts and online diagnosis. It can operate efficiently in an ambient temperature range of -30 ° C to 43 ° C, with a maximum water outlet temperature of 60 ° C. It comes in various terminal forms and is suitable for radiators and floors Radiation, central air conditioning for 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.

Operation range of air-cooled screw type cold (hot) water unit
● Large diameter heat exchanger, low temperature operation effectively reduce refrigerant flow resistance, increase evaporation pressure, inhibit frost;
● Large distance aluminum foil design, low temperature operation effectively reduce air flow resistance, increase evaporation pressure, inhibit frost;
● Fin flow independent control, accurate control, more thorough defrosting;
● Concentrated a variety of innovative technologies, distributed defrosting system and piston type four-way directional valve effectively avoid the suction of traditional air-cooled heat pump units With liquid, defrosting incomplete, four way directional valve stuck and so on.
