Sujing Reliable Operation Water/Ground Source Heat Pump for Commercial buildings
As one of China's earliest professional manufacturers of purification air conditioners and HVAC equipment, Sujing specializes in R&D, production, sales, and installation. We operate two core segments: air conditioning systems and heat pump systems. The heat pump line includes CO2 heat pumps, cascade variable frequency units, air source (chilled water) units, water-cooled chillers, industrial screw units, air-cooled modules, and drying units.
Our products are widely applied in industry, agriculture, commerce, transportation, and aerospace, as well as in specialized fields like green heating, coal mines, oil fields, livestock farming, agricultural drying, and biomedicine. They are exported to over 30 countries, including the U.S., Finland, the Netherlands, Canada, and Brazil.
Sujing Customizable Water / Ground Source Heat Pump
updated in 2025-11-18
Flooded Water (Ground) Source Heat Pump Unit (R22) - Ground water type
The water (ground) source heat pump system is an efficient and energy-saving air conditioning system that utilizes shallow geothermal resources underground (also known as geothermal energy, including groundwater, soil, or surface water) for both heating and cooling. The system uses a small amount of electricity to transfer low-grade thermal energy to high-grade heat, with geothermal energy serving as the heat source for heat pump heating in winter and the cold source for air conditioning in summer. The unit consumes 1 kW of energy and provides 4-7 kW or more of heating/cooling capacity. With its energy derived from underground sources, the system does not emit any waste gas, water, or residue to the outside, making it an dieal "green air conditioning" solution suitable for a wide range of applications in electronics, photovoltaics, medical, and other fields.

Remarks:
1) Refrigeration nominal working conditions: evaporator inlet/outlet water temperature 12/7°C, Condenser inlet/outlet water temperature 18/29°C.
2) Nominal heating conditions: the inlet/outlet water temperature of the evaporator is 15/7°C, and the inlet/outlet water temperature of the condenser is 40/45°C.
3) Refrigeration and total heat recovery working conditions:the inlet/outlet water temperature of the evaporator is 12/7°C,and the inlet/outlet water temperature of the condenser is 40/45°C.
4) "Heating" in the parameter table is only the parameter of the heat pump type unit, and the single cooling type unit does not have.
5) "Refrigeration and total heat recovery" in the parameter table is only the parameter of the total heat unit, not for the single cooling and heat pump unit.
6) The water pressure drop of the evaporator and condenser does not include the resistance of any external water pipes and components.
7) Please refer to the unit nameplate of installation manual for the unit on-site power distribution and wiring.
8) Specifications are subject to change with product improvements, please refer to the actual product.
9)
Customization is available according to the customer's actual requirements.
