Product Description
Product Introduction:
Different from the conventional electric driven heat pump unit, the screw water source gas engine heat pump unit uses the gas engine instead of the motor to drive the compressor, and directly uses the primary energy natural gas as the driving energy, which eliminates the loss of energy in the process of transformation and transmission. At the same time, the perfect waste heat recovery system can recover most of the waste heat of the gas engine and can be used to heat domestic hot water. Therefore, the primary energy efficiency of screw water source gas engine heat pump unit is higher than that of electric drive unit. During the refrigeration operation of the unit, the evaporator is used as the heat taking side, and the chilled water absorbs the heat of users and provides air conditioning water of 5 ºC ~ 7 ºC for the building. During the heating operation of the unit, the condenser is used as the heat release side, and the cooling water provides heat for users and releases the heat extracted from external water sources to the indoor environment.
