   Product overview
Full liquid water (ground) source heat pump is a high-efficiency and energy-saving product developed by the majority of R & D workers of chundao geoenergy Air Conditioning Co., Ltd. on the basis of absorbing advanced refrigeration technology at home and abroad.
The unit adopts full liquid special screw compressor and external secondary oil separator, which makes the inner surface of evaporator free of oil film and improves heat exchange efficiency. Perfect control logic and high-precision electronic expansion valve control refrigerant ensure stable operation of the unit.
This product is suitable for: hotels, shopping malls, office buildings, industrial and mining enterprises, residential quarters, office buildings and other places for heating and cooling, and can also provide domestic hot water.
   Product features
The low volume ratio screw compressor is used to avoid the compression power loss caused by over compression or under compression, effectively reduces the input power of the unit and improves the energy efficiency ratio of the unit.
The advanced oil return system solves the problems of high steam pressure and small compression ratio in refrigeration system, and fully aspirated concentrated oil return system ensures that the compressor does not lack oil.
Full liquid evaporator: high heat exchange efficiency, more than 3 times of dry evaporator, effectively improving the refrigeration and heating capacity and energy efficiency ratio of the unit.
The unit uses electronic expansion valve with high precision, fast response and wide range.
Full liquid compressor, low noise, small vibration, stable and reliable operation.
Green environmental protection; heating in winter, no combustion, no exhaust gas, waste residue, waste water emissions, no greenhouse gas emissions, environmental protection, is an ideal green environmental protection products;
One unit with multiple functions: one unit can provide heating in winter or cooling in summer. At the same time, it can use heat recovery and zero cost. It can also provide domestic hot water instead of boiler and air conditioner
Good large screen man-machine interface can display the working state of the unit; the parameter setting is flexible and the fault inquiry is convenient.
