Air Source Low Temperature DHW Heat Pump DKFXRS-9I/CY
Features of Air Source Heat Pump for Cooling and Heating House Suppliers
This kind of ultra-low temperature air energy heat pump automatic heat collection system includes a main circuit composed of a compressor system, a heat exchanger, a liquid storage tank, an expansion valve and an evaporator connected in sequence; the compressor system includes a main compressor and a branch circuit Compressor unit; the branch compressor unit is connected with a control module; the heat exchanger is connected to an external circulating water pipe, and the high-pressure and high-temperature gas exchanges heat with water to form a high-pressure and low-temperature liquid; the liquid storage tank is used for the liquid in the main circuit The expansion valve can convert high-pressure low-temperature liquid into low-pressure low-temperature liquid, the low-pressure low-temperature liquid absorbs heat in the air through the evaporator, and the refrigerant becomes a low-temperature and low-pressure gas and returns to the compressor system. The utility model is optimized on the basis of the traditional air heat pump system, the design is reasonable, the operation is stable and reliable, it can still work effectively in a low temperature environment, and meet the thermal energy demand of users in daily life.
