Product Description

1)The Feature of  Water,Ground-Source heat pump screw type chille
a. Optimized design
     International standards are fully abided by, and modular system design ensures high reliability;large temperature difference and small flow technical idea is able to minimize user's water consumption and reduce expenses for runnin; and optimized computer-aided control ensures the unit runs in the best status regardless of the working conditions.
b.Excellent performance
The main body is equipped with globally advanced semi-hermetic screw compressor,intergrating the motor,without worrying about shaft seal leakage.
The single or number of compressors are provided with startup-shutdown cycle control program so as to uniformly load parts and extend their service life.
Multiple refrigrating cicuits are provided for the sigle or number of comprssors ,and when on cicuits is under maintenance,other cirucits are albe to run nomally as mutual standby.
Unload deprssurized start is provided for the compressors to prevent the impact on the power grid
c. Wide scope of application
Scope of water source temperature applicable for the unit:8-35ºC;7ºCor 45ºC air conditioner coled/hot water as well as 50ºC hot water for living can be provided;in addition,high-temperature units can provide as high as 60ºC hot water, directly used for original radiating  fin heating system or for regional urban heat supply.
d.Complete safety protections
Pressure protection:High and low-pressure protecting devices
Motor protection:Voltage-loss protection, phase-loss protection,inverse phase protection and over-heat protection.
Anti-freezing protiction:The unit will stop running in case of excessively low cooling water temperature
Safety valve protection:when the refrigerant pressure exceeds a certain value, the safety valve will be turned on automatically
Above device  protections ensure the safe and reliable running of the unit
