Ground source heat pump system is an ideal "green air conditioning". The system can be used in both cold and tropical areas. It can be widely used in office building, workshop, warehouse, etc.

"The specific application conditions are as follows:
(1) Application conditions of surface (underground) water ground source heat pump system:
There are abundant surface water (such as river water, river water, lake water, sea water, reservoir water, sewage, reclaimed water, geothermal tail water, industrial waste water, etc.) or groundwater near the construction project, so as to ensure that the water temperature is moderate, the water quality is appropriate, the water supply is stable, and the recharge is smooth, which is convenient for the implementation of water supply and return projects.
However, due to the lack of water resources nearby, there must be enough water resources to be laid nearby. (e.g. green land before and after the office building, etc.)
(2) Advantages of industrial water ground source heat pump:
If the office building or workshop is large, using central air conditioning can save energy than ordinary air conditioning. If someone forgets to turn off the air conditioner after work, the central air conditioner can realize the external shutdown.
The maintenance cost is small. For example: the same is the indoor unit failure, the central air conditioning only needs to replace the indoor coil, the price is several hundred yuan, and the split unit can only be replaced as a whole, the price is about 2000 yuan.
As far as the indoor layout is concerned, the indoor installation of central air conditioning is relatively unified and tidy after simple decoration.
Installation of central air conditioning can save installation of heating equipment, one machine for three purposes, energy saving and environmental protection.
The central air conditioner is equipped with fresh air device, which can keep the indoor air fresh by introducing fresh air, effectively improve the indoor air quality, avoid the trouble of "air conditioning disease", and greatly improve the working environment.

Spring Island water ground source heat pump air conditioning unit adopts high efficiency, reliable, stable and maintainable semi closed screw refrigeration compressor. The compressor has reasonable structure, precise manufacturing technology, reduced cross flow between high and low pressure, wide operating pressure range of the compressor, high exhaust continuity and small pulsation, because of the low vibration and noise of the unit. The differential pressure oil supply mode has the advantages of simple structure, convenient maintenance and more reliable operation.
The heat exchanger has high heat exchange efficiency, energy saving and power saving
The evaporator and condenser adopt high-efficiency heat exchange tubes, and the tube bundle process layout is reasonable to ensure that the refrigerant has sufficient undercooling, improve the energy efficiency ratio and reduce the input power of the press. The refrigeration capacity of the unit can be adjusted according to the load to match the actual load, so as to improve the efficiency of the compressor, reduce energy consumption and prolong the service life of the unit.
The control adopts the logic intelligent controller independently developed by the company
RS232 / 485 can be used to monitor and control the unit's operation status, and realize the functions of remote monitoring, automatic monitoring, automatic shutdown, and automatic display of the unit.
Complete protection and stable operation

  1. Water pump interlock linkage energy automatic regulation
  2. Protection of over high exhaust temperature in multi compressor balanced operation
  3. Cold and warm water temperature control technology compressor delayed start
  4. Anti freezing and water cut-off protection function of air conditioning water pump

High pressure and low pressure over limit shutdown protection oil pressure difference protection
Compressor over current shutdown protection evaporator outlet water temperature protection
Compressor shutdown time protection compressor oil level low shutdown protection
Compressor motor lack of phase protection, reverse phase protection, motor winding temperature is too high shutdown protection.
