Abstract

the Technology of Replenishing Gas Can Increase the Heating Capacity and Reduce the Exhaust Temperature of Compressor. Based on the Basic Principle of the Compressed Heat Pump System, This Paper Carried out Repeated Experiments in the Same Air Source Heat Pump System to Test the Specific Impact of the Air Replenishment Technology on the Performance of the Low-Temperature Air Source Heat Pump Water Heater. the Results Show That the Air Supply Technology Has a Significant Impact on the Performance of the Low-Temperature Air Source Heat Pump Water Heater. When the Relative Air Supply Increases by 12.73%, the Heating Capacity Will Increase by 9.28kw and the Heating Capacity of the System Will Be Improved. When the Vent Hole Diameter of the Make-Up Hole of the Compressor is Fixed, the Maximum Make-Up Pressure Will Appear, and the Heating Efficiency of the System Will Reach the Maximum At This Time. When the Temperature of the Refrigerant is Well Regulated, the Safe Operation of the Expansion Valve Can Be Ensured.
