Abstract

The invention relates to a combined operation system of an air source heat pump air conditioner and a heat pump water heater. The combined operation system comprises an air source heat pump air conditioning mechanism, a water storage tank mechanism and an air source heat pump water heater mechanism. The air source heat pump air conditioning mechanism and the water storage tank mechanism are connected in a heat exchange mode, and the water storage tank mechanism and the air source heat pump water heater mechanism are connected in a heat exchange mode. According to the combined operation system,compared with the prior art, waste heat of the air source heat pump air conditioning mechanism is collected, a heat source is conveyed to the air source heat pump water heater mechanism, and the energy utilization efficiency of the system is optimized; the defrosting efficiency of the heat pump in winter is improved, and energy of a heat source during defrosting comes from energy of a supercooling section which cannot be utilized during heat supply in original circulation, so that energy does not need to be introduced from the outside, or the heat of hot water supply or heat supply of an original heat pump is not occupied, and extra energy consumption is avoided; and construction of the scheme can be completed on the basis of common facilities in a public building. The system is high in universality and wide in application range, and the system is easy to control and simple in control scheme.

Description

technical field [0001] The invention relates to the field of heat pump systems, in particular to a combined operation system of an air source heat pump air conditioner and a heat pump water heater. Background technique [0002] In large public buildings, there is a huge building energy consumption, among which domestic hot water and air conditioning take the largest proportion of building energy consumption. In order to save energy, air source heat pumps are often used in the market for heating. By taking heat from the outdoor air, the efficient use of electric energy can be realized, and energy saving and environmental protection can be achieved. However, when the air source heat pump is used in low temperature conditions, frosting is prone to occur. In addition, there is a lack of connection between different heat pump systems, and the design of energy utilization schemes is relatively scarce. [0003] At present, the commonly used defrosting schemes in the market are el...
