Referring to fig. 1, an embodiment of the present disclosure provides a composite air conditioning and hot water integrated application system 1, which includes a water storage tank 10, an air conditioning system 20, and a solar energy integrator 30. The water tank 10 is used for storing domestic water, and is provided with a domestic water interface 101. The air conditioning system 20 includes a coolant circulation loop 201 and a refrigerant circulation loop 202. The coolant circulation loop 201 includes a coolant flow path 2011 of a first heat exchanger, a second heat exchanger 2012, an expansion tank 2013, and a water pump 2014, which are in communication in sequence. The second heat exchanger 2012 is disposed inside the water tank 10. Wherein the coolant in the coolant circulation loop 201 exchanges heat with the service water in the water storage tank 10 through the second heat exchanger 2012; the refrigerant flow path 2021 of the first heat exchanger taps into the refrigerant circulation circuit 202 to effect heat exchange between the refrigerant and the coolant. One end of the solar energy integrator 30 is communicated with the water storage tank 10 through a water supply pipeline.

According to the composite air-conditioning and hot water integrated application system 1 provided by the embodiment of the disclosure, solar energy and the air-conditioning system 20 are comprehensively utilized, heat exchange is carried out between the solar energy and domestic water in the water storage tank 10 through the second heat exchanger 2012, and under the condition that the solar energy is insufficient for heating the domestic water, the secondary refrigerant circulation loop 201 of the air-conditioning system 20 is utilized for carrying out auxiliary heating on the domestic water, so that the integrated application system 1 can raise the temperature of the domestic water, and the use is convenient. Meanwhile, under the condition that solar energy is sufficient for heating the domestic water, the solar energy is utilized to convert the light energy into heat energy, so that the domestic water in the water storage tank 10 is used for carrying out auxiliary heating on the secondary refrigerant circulation loop 201 of the air conditioning system 20, thereby greatly reducing the power consumption load, and further saving energy when the temperature of the domestic water is raised.

The water storage tank 10 is a heat preservation water tank, so that heat loss of domestic water is avoided, and the heat preservation effect of the domestic water is improved. The domestic water interface 101 is arranged to facilitate the supply of hot water to the user side. A water pump 2014 is provided in the coolant circulation loop 201 to regulate the flow rate of the coolant in the coolant circulation loop 201 so that the coolant circulation is more stable and uniform. By providing the expansion tank 2013, pressure uniformity and uniformity in the coolant circulation loop 201 are ensured, and use safety and reliability of the coolant circulation loop 201 are improved.

Alternatively, the coolant is water. The coolant circulation loop 201 is a water circulation loop.

Optionally, as shown in connection with fig. 1, the coolant circulation loop 201 also includes a first control valve 2015. The first control valve 2015 is connected to a line between the outflow port of the coolant flow path 2011 of the first heat exchanger and the inflow port of the second heat exchanger 2012, and the first control valve 2015 is turned on or off to turn on or off the coolant circulation circuit 201.

In this embodiment, a first control valve 2015 is provided in the coolant circulation circuit 201, and the first control valve 2015 is turned on or off to turn on or off the coolant circulation circuit 201. When the heating temperature of the solar energy to the domestic water is lower than the temperature required by the domestic water, the auxiliary heating of the domestic water by the coolant circulation circuit 201 in the air conditioning system 20 is required, and the first control valve 2015 is turned on to realize the conduction of the coolant circulation circuit 201. Thereby causing the second heat exchanger 2012 disposed inside the water storage tank 10 to exchange heat with the domestic water to raise the temperature of the domestic water. Under the condition that the heating temperature of the solar energy to the domestic water is equal to the temperature required by the domestic water, the auxiliary heating of the domestic water by using the secondary refrigerant circulation loop 201 in the air conditioning system 20 is not needed, and the first control valve 2015 is closed to realize the stop of the secondary refrigerant circulation loop 201, so that the energy waste is avoided. When the heating temperature of the solar energy to the domestic water is greater than the required temperature of the domestic water, the first control valve 2015 is turned on to realize the conduction of the secondary refrigerant circulation circuit 201, so that the domestic water in the water storage tank 10 carries out auxiliary heating to the secondary refrigerant circulation circuit 201 of the air conditioning system 20, and the electricity load is greatly reduced.

Because the coolant circulation circuit 201 of the air conditioning system 20 uses coolant circulation, frequent start-up and shut-down of the air conditioning system 20 can be caused under the condition of insufficient dosage of circulating coolant in the coolant circulation circuit 201, and the service life of the air conditioning system 20 can be reduced. By providing the buffer tank 2016 to store coolant, sufficient coolant can be provided to the coolant circulation circuit 201 in the event of insufficient doses of circulating coolant, avoiding frequent start-up and shut-down of the air conditioning system 20, and extending the service life of the air conditioning system 20. Meanwhile, by arranging the buffer water tank 2016, the defrosting efficiency of the air conditioning system 20 can be improved, and smooth circulation of the refrigerating medium of the air conditioning system 20 can be ensured, so that the pollution discharge of the air conditioning system 20 is more thorough.

In this way, when the coolant flowing out through the outflow port of the second heat exchanger 2012 is insufficient, the coolant is first replenished by the buffer tank 2016, so that the coolant in the coolant circulation circuit 201 is sufficient. In the event that the coolant in the coolant circulation system is sufficient, the expansion tank 2013 is used to eliminate pressure fluctuations due to changes in water temperature, thereby avoiding damage to other system control elements. By such a positional relationship, the uniformity and uniformity of the pressure in the coolant circulation circuit 201 of the air conditioning system 20 are further improved, thereby improving the safety of the air conditioning system 20.

In this embodiment, by providing the auxiliary branch 203 and the second control valve 204, the domestic water in the water tank 10 flows into the coolant circulation circuit 201 in one direction, so that the coolant in the coolant circulation circuit 201 in the air conditioning system 20 is prevented from flowing into the water tank 10, and the safety of the domestic water in the water tank 10 is improved.

Optionally, as shown in connection with fig. 3, the auxiliary branch 203 further comprises a third control valve 2031. The third control valve 2031 is interposed between the second control valve 204 and the first position 205.

In this embodiment, the auxiliary branch 203 is controlled to be turned on or off by controlling the third control valve 2031 to be turned on or off. Under the condition that the temperature of the domestic water is higher, the third control valve 2031 is controlled to be conducted so as to realize the conduction of the auxiliary branch 203, so that the domestic water directly flows into the secondary refrigerant circulation loop 201, the use effect of the air conditioning system 20 is further improved, and the energy conservation and consumption reduction are realized.
