Embodiment 1

[0046] See Figure 1 to Figure 4 , an air-conditioning and hot-water composite machine, the air-conditioning and hot-water composite machine includes a circulation circuit for an air-conditioning system composed of a first compressor 1, a first heat exchanger 2, a second heat exchanger 3, and a first throttling mechanism 4 , and a hot water heating circulation loop composed of the second compressor 5, the third heat exchanger 6, the fourth heat exchanger 7, and the second throttling mechanism 8; the second heat exchanger 3 and the third heat exchanger The heat exchanger 6 forms a heat exchange connection; the fourth heat exchanger 7 forms a waterway connection with the hot water pipeline, and the hot water pipeline is provided with a water inlet and a water outlet; the water inlet and the water outlet are connected to the heat storage tank 9 at the same time, and A hot water pump 13 is arranged on the hot water pipeline, and a water inlet pipe 14 and a water outlet pipe 15 are...

Embodiment 2

[0066] Please refer to Fig. 5, the difference between this embodiment and the first embodiment is that the fourth heat exchanger 7 is a coil type immersed in the heat storage tank 9, and the high-temperature and high-pressure gaseous refrigerant discharged by the second compressor 5 Enter the fourth heat exchanger 7 through the second four-way valve 20 to condense and release heat, and heat the water in the hot water storage tank 10 through the released condensation heat, so that the temperature of the water stored in the hot water storage tank 9 gradually increases , to achieve the effect of producing hot water. After the refrigerant is condensed in the fourth heat exchanger 7, it is throttled by the second throttling mechanism 8 and then enters the third heat exchanger 6 to evaporate and absorb heat. The second four-way valve 20 re-enters the second compressor 5 .

Embodiment 3

[0068] Please refer to FIG. 6 , the difference between this embodiment and the first embodiment is that the first heat exchanger 2 is a water-refrigerant type, which cools or heats the circulating water of the air conditioner.

[0069] During refrigeration, the high-temperature and high-pressure gaseous refrigerant discharged from the first compressor 1 enters the second heat exchanger 3 through the first four-way valve 10 to exchange heat with the outdoor air to release heat. At this time, the second heat exchanger 3 is used as a condenser. The condensed refrigerant liquid enters the first heat exchanger 2 after throttling through the first throttling mechanism 4, exchanges heat with the air-conditioning circulating water in the first heat exchanger 2, reduces the temperature of the circulating water, and passes through the air-conditioning circulating water pump 18 The refrigerant circulates into the indoor coil 17 for cooling the room, and the refrigerant re-enters the first...

Abstract

The invention discloses an air-conditioning/water-heating compound machine which comrprises (1) a circulation loop for an air-conditioning system, consisting of a first compressor, a first heat exchanger, a second heat exchanger and a first throttle mechanism; and (2) a circulation loop for a water-heating system, consisting of a second compressor, a third heat exchanger, a fourth heat exchanger and a second throttle mechanism. The second heat exchanger and the third heat exchanger form a heat-transfer connection. The fourth heat exchanger and a hot-water pipeline form a water-passage connection. The hot-water pipeline is provided thereon with a water inlet and a water outlet. The invention can reduce energy consumption and has simple structure.

Description

technical field [0001] The invention relates to the fields of air conditioners and hot water supply, in particular to an air conditioner and hot water composite machine. Background technique [0002] At present, in homes, schools, hotels, etc., the air conditioners and domestic hot water devices used are two separate devices, and the purchase, use, and maintenance costs are high. Moreover, when the air conditioner is refrigerated, a large amount of condensation heat is released into the atmosphere. On the other hand, heating domestic hot water through water heaters or boilers consumes a lot of high-grade energy, which not only causes energy waste, but also causes environmental thermal pollution. After retrieval, the existing technology of using the condensation heat of the air conditioner to heat domestic hot water is mainly to connect a water-cooled heat exchanger in series between the compressor exhaust and the heat exchanger, such as patent numbers 200410023767.2 and 0326...
