<p>Abstract The present invention discloses a double-compressor air-source heat pump heating and heat supply system, which includes a unit part, a heating part, a heat supply part, and an intelligent control part. The unit part includes an air-source heat pump heating part, an electric heating part, a water pipeline fittings part and a control circuit part. The control circuit part is used for controlling the air-source heat pump heating part on using different compressor combinations according to the detected inflow temperature and ambient temperature; the control circuit part is further used for controlling no output of the electric heating part when detecting that after compressor start-up, the outflow temperature reaches the set temperature; the control circuit part is further used for controlling the electric heating power required for the output of the electric heating part according to the detected inflow and outflow temperature difference as well as the flow quantity detected by the water pipeline fittings part when detecting that the set temperature cannot be reached; the control circuit part is further used for controlling the water pipeline fittings part on regulating the water flow via water flow regulating valve based on the detected temperature to make the water temperature constant when the air-source heat pump heating part and the electric heating part are both of full-power output and the outflow temperature has not reached the set temperature.</p> |
