Mini Type ground source heat pump is an energy-saving and environment-friendly air-conditioning system that uses underground shallow geothermal resources, also known as geothermal energy, including groundwater, soil or surface water, etc. When cooling down in summer, the ground is used as a heat dissipation place, and the indoor heat and the energy consumption of the compressor are discharged into the ground through the embedded coil, and then the heat is diffused through the heat conduction of the soil and the migration of water in the soil. When heating in winter, the earth is used as the low-temperature heat source of the heat pump unit, and the heat in the soil is obtained through embedded coils for indoor heating.
● Choose broad
Unit integrates the functions of refrigeration, heating and sanitary hot water;
units has R22, R403C or R410A refrigerants to choose from.
● Advanced technology
Mini type ground source heat pump unit uses a variety of advanced air conditioning technologies, such as multi-level energy regulation, unique built-in heat recovery technology, and precise unit water side antifreeze technology!
● Smooth operation, quiet and low noise
Unit adopts a fully enclosed scroll compressor, a horizontal multistage centrifugal pump, a fully enclosed structure shell, low noise, and stable operation.
● Digital centralized control, accurate and efficient
The compressors, refrigeration system accessories, and electric control components used in the unit are all products from well-known companies at home and abroad, with accurate control and reliable performance. The controller has a friendly operation interface, and the user can know the operation status of the unit at any time.
● Complete protection, safe and reliable
The units are equipped with high pressure, low pressure switches, overload relays, phase sequence protectors, antifreeze protection and delay start protection devices to ensure safe and reliable operation of the main engine.
● Simple installation and complete functions
The internal direction of the refrigeration system is reversible, and the external refrigerant system does not need a cooling and heating switching valve, which makes the installation of the entire air conditioning system simple and tidy, just like a household air conditioner is easy to operate. The unit can be installed and fixed only by making a simple cement foundation.
