DOUBLE-COMPRESSOR AIR-SOURCE HEAT PUMP HEATING AND HEAT SUPPLY SYSTEM

摘要

The present invention 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 can control the heating part to use different compressor according to the temperature of water and environment; if the outflow temperature cannot reach the standard that the electric heating part would work according to the difference of inflow and outflow temperature as well as the flow quantity, to the contrary, it won't work; if both of the air-source heat pump part and the control circuit part worked but the temperature still cannot reach the set temperature that the water flow regulating valve will used to make the water stay in constant temperature.

1. A double-compressor air-source heat pump heating and heat supply system, characterized in that, including 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 outflow temperature cannot reach the set temperature; 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; the control circuit is further used for judging whether it is necessary to execute the heat supply command according to the detected indoor ambient temperature or floor heating coil temperature when receiving a heat supply command, specifically, execute the heat supply function when the indoor ambient temperature or floor heating coil temperature reaches the heat supply-required temperature, and close the heat supply function when detecting that the indoor ambient temperature or floor heating coil temperature reaches the shutdown temperature.
