The invention relates to a reactive compensation control system and method for an air source heat pump. The reactive compensation control method comprises the steps of: collecting three-phase apparentpower and a power factor of the air source heat pump through using an electric parameter instrument; calculating a real-time capacitance compensation amount after fan operation and compressor operation in the operation process of the heat pump and a real-time capacitance compensation amount after step-by-step stop part of a compressor in the stop process of the heat pump respectively by means ofa PLC according to the three-phase apparent power and the power factor; and controlling a capacitance switching device to compensate the corresponding capacitance compensation amount in a three-phasepower capacitor into a main circuit of the heat pump according to the real-time capacitance compensation amount. Therefore, real-time reactive power compensation of the heat pump is achieved, reactivepower loss of the heat pump is reduced, and the energy-saving performance of the heat pump is further improved.
Description
technical field [0001] The invention relates to the technical field of reactive power compensation control, in particular to an air source heat pump reactive power compensation control system and method. Background technique [0002] In the actual operation of the heat pump process, due to the crossing of the four seasons and the temperature of the outlet water rising from low temperature to high temperature, the range of operating conditions of the compressor is too large, resulting in a very low power factor of the compressor in a certain working condition, and the reactive power in the initial operation stage of the heat pump. The loss is greater than or equal to 40%, even if the heat pump runs to the demand condition, the reactive power loss is also 20%. [0003] Air source heat pump is an energy-saving technical product, which has been widely promoted and applied. However, during the test, it was found that the power factor of the host of the air source heat pump was b...
