Airsour water source heat pump screw unit
Five times energy saving
Using water as medium, it exchanges heat with the ground: releasing indoor heat into the ground for cooling in summer, extracting geothermal heat for heating in winter, and making hot and cold water at the same time; various water temperatures can be made: it can meet the demand for ordinary hot and cold water in office buildings, hospitals, shopping malls and other places, and also provide hot water above 50℃ to meet the demand for domestic hot water.
High energy efficiency ratio: Compared with the surface air, the temperature difference between winter and summer in the ground is small, so the heat exchange with the ground consumes less energy. The energy efficiency ratio of the unit is higher. Especially when the unit is heating, the energy efficiency is 5 times higher than the common electric heating method.
High application range:It can work in water source temperature from 8-35℃, and the highest water outlet temperature is up to 55℃.
Principle of water (ground) source heat pump
Water (ground) source heat pump is an energy-efficient system that uses shallow underground geothermal resources (also known as ground energy), including groundwater, earthfill or surface water, for both heating and cooling.
It is an energy-efficient system that can supply heat and cool water.
The system achieves the transfer of low-frequency heat energy to high-frequency heat energy by inputting a small amount of electrical energy, and the ground energy is used as the heat source for heat pump heating in winter and the cooling source for air conditioning in summer, respectively.
The system consumes 1kW of energy and obtains more than 4-5kW of cooling/heat, and the energy comes from underground energy.
The system does not discharge any waste gas, waste water and waste residue to the outside world, which is an ideal high-efficiency and energy-saving air conditioning system.

Host [Outdoor Unit]
Absorb energy from natural air to heat or cool water medium; natural energy, low carbon, environmental protection, energy saving!
Expansion tank [outdoor unit]
Accommodates the expansion volume of system water in the heating system, and also plays the role of pressure fixing and water replenishment for the system.
Terminal [Fan Coil]
At the end of a central air conditioning system, the coil flows through chilled water or hot water and exchanges heat with the air outside the coil to cool, dehumidify or heat the air to regulate the indoor air parameters.
Terminal [Underfloor Heating]
Floor heating is the most ideal way of comfortable heating, and the vertically reduced temperature distribution keeps the human foot warm and the mind awake, which is in line with the Chinese medicine "cool top and warm foot" health care.
