Geothermal Heat Pump
Product introduction：
Air source heat pump is a kind of energy-saving device that can make the heat flow from the low heat source air to the high heat source.
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, 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.
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.
Application scope:
Comfort air conditioning systems: large supermarkets or commercial complexes, hotels, shopping malls, office buildings, exhibition halls, airports, stadiums, etc.
Process air conditioning systems: electronics, biology, light textile, chemical engineering, metallurgy, pharmaceuticals, power, machinery, etc.
Working principle
When the air-cooled water chiller is working, the refrigerant absorbs the heat from the cooled object in the evaporator and vaporizes. The compressor continuously draws the gas generated in the evaporator and compresses it into high-temperature and high-pressure vapor. The refrigerant vapor is then sent to the condenser to exchange heat with the air. After releasing heat, it condenses into liquid. The liquid refrigerant is decompressed after passing through the expansion valve. Then it enters the evaporator to absorb the heat of the cooled object and vaporizes again. This heat exchange process is repeated until the industrial water is cooled to the required temperature.
