Description

Technical Field

[0001] This utility model relates to the field of air conditioning, specifically a heat exchange module and a unit-type dual-supply air conditioning system. Background Technology

[0002] Conventional split-type air conditioners have the following three problems that lead to lower indoor comfort levels when heating in winter:

[0003] 1) Uneven indoor air temperature: The indoor unit of the air conditioner is installed in the upper part of the space. When heating in winter, hot air is blown out from the top and accumulates in the upper part of the space, resulting in a higher temperature in the upper part and a lower temperature in the lower part. However, people prefer a slightly higher temperature in the lower part and a slightly lower temperature in the upper part.

[0004] 2) The indoor unit's air outlet temperature is too high: The high-temperature gas refrigerant in the air conditioner's indoor unit directly exchanges heat with the indoor air, resulting in a high air outlet temperature. If it blows directly onto people, it will feel uncomfortable.

[0005] 3) Large fluctuations in indoor temperature: When the outdoor unit of the air conditioner freezes and enters the defrosting mode, the indoor unit cannot continue to output heat, causing the indoor temperature to drop rapidly; when the indoor unit exits the defrosting mode and starts heating, the indoor temperature will rise rapidly again, resulting in large temperature fluctuations and low human comfort. Utility Model Content

[0006] The purpose of this invention is to provide a heat exchange module and a unit-type dual-supply air conditioning system to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A heat exchange module includes a water-cooled condenser. The refrigerant port of the heat exchange module is connected to the refrigerant port of an outdoor air conditioning unit via a pipeline. The heat exchange module generates hot water through the water-cooled condenser. The water port on the heat exchange module is connected to a heating device for indoor heating.

[0009] Furthermore, the heat exchange module also includes a water pump, which together with the water-cooled condenser and heating equipment forms a circulating water circuit.

[0010] Furthermore, the refrigerant port of the heat exchange module is connected to the refrigerant port of the indoor unit of the air conditioner via a pipeline.

[0011] Furthermore, the heat exchange module also includes a humidification component.

[0012] Furthermore, the humidification assembly includes a first fan, a humidification water curtain, and a humidification water tank.

[0013] Furthermore, the heat exchange module also includes a fresh air component.

[0014] Furthermore, the fresh air assembly includes a second fan and an air filter.

[0015] Furthermore, the heat exchange module also includes a housing, and the water-cooled condenser is disposed within the housing.

[0016] Furthermore, the enclosure is installed indoors and located next to the heating equipment.

[0017] Furthermore, the housing is connected to the heating equipment.

[0018] Furthermore, the heating equipment is a radiator.

[0019] This utility model also includes a unit-type dual-supply air conditioning system, comprising a heat exchange module, an outdoor air conditioning unit, and a heating device as described above. The refrigerant port of the heat exchange module is connected to the refrigerant port of the outdoor air conditioning unit via a pipeline, and the water port on the heat exchange module is connected to the heating device for indoor heating.

[0020] Furthermore, it also includes an indoor air conditioner connected to the outdoor air conditioner unit via a pipeline, wherein the refrigerant port of the heat exchange module is connected to the indoor air conditioner unit via a pipeline to deliver the refrigerant that has undergone heat exchange to the indoor air conditioner unit.

[0021] Furthermore, the outdoor unit of the air conditioner is connected to a valve device. The valve device controls the dual-supply air conditioning system to allow the refrigerant to pass through the heat exchange module during heating, while preventing the refrigerant from passing through the heat exchange module during cooling.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1) Increase the temperature in the lower part of the room for a more comfortable feeling. Radiators are generally installed in the area within 1 meter of the ground. Cold air at the bottom naturally enters the radiator, is heated by the radiator and is output from the top. At the same time, the radiator can also dissipate heat through radiation.

[0024] 2) Since the refrigerant has already undergone one heat exchange with the water-cooled condenser, the indoor unit's outlet air temperature can be reduced;

[0025] 3) The indoor temperature fluctuates little. Even if the outdoor unit stops heating due to defrosting, it can still rely on the high-temperature water in the radiator to continuously input heat. Attached Figure Description

The fresh air assembly includes a second fan 6 and an air filter 11. The air filter 11 is disposed on the air inlet of the cover 12, and the second fan 6 blows out the incoming fresh air.

[0038] Continue reading Figure 3 and Figure 4 The housing 12 is installed indoors and located next to the heating equipment. The housing 12 is connected to the heating equipment, so that the heating equipment and the heat exchange module can be installed together, which is more convenient.

[0039] Furthermore, the aforementioned heating equipment is preferably a radiator.

[0040] Please see Figures 1-5 A unit-type dual-supply air conditioning system includes an outdoor air conditioning unit 1, a water-cooled condenser 5, and a heating device. The refrigerant port of the heat exchange module 4 is connected to the refrigerant port of the outdoor air conditioning unit 1 through a pipeline. The heat exchange module 4 generates hot water through the water-cooled condenser 5. The water port on the heat exchange module 4 is connected to the heating device for indoor heating.

[0041] Continue reading Figure 2 In one embodiment of this utility model, the unit-type dual-supply air conditioning system further includes an indoor air conditioning unit 2, and an outdoor air conditioning unit 1 has a heating outlet 100 and a cooling outlet 101. The heating outlet 100 is connected to the heat exchange module 4, and the cooling outlet 101 is connected to the indoor air conditioning unit 2. The refrigerant channel 500 is connected to the indoor air conditioning unit 2 through a pipeline to transport the refrigerant that has undergone heat exchange to the indoor air conditioning unit 2.

[0042] Furthermore, the outdoor unit 1 of the air conditioner is equipped with a valve device on the pipeline connected to the indoor unit 2 of the air conditioner and the water-cooled condenser 5. The outdoor unit 1 of the air conditioner is connected to the valve device. The valve device controls the dual-supply air conditioning system to allow the refrigerant to pass through the heat exchange module 4 when heating, and to prevent the refrigerant from passing through the heat exchange module 4 when cooling.

[0043] Specifically, such as Figure 5 As shown, the valve device includes a first one-way valve 13 and a second one-way valve 14. The outdoor unit 1 controls the refrigerant flow from the heating outlet 100 or the cooling outlet 101 via a four-way valve. The cooling outlet 101 of the outdoor unit 1 is directly connected to the indoor unit 2 via a pipe. The heating outlet 100 of the outdoor unit 1 is connected to the first one-way valve 13 via a pipe, and the first one-way valve 13 is connected to the indoor unit 2 via a pipe. The heating outlet 100 of the outdoor unit 1 is also connected to the refrigerant inlet of the heat exchange module 4 via a pipe. The refrigerant outlet of the heat exchange module 4 is connected to the second one-way valve 14, and the second one-way valve 14 is connected to the indoor unit 2. The first one-way valve 13 allows refrigerant to flow from the indoor unit 2 to the outdoor unit 1 but does not allow reverse flow. The second one-way valve 14 allows refrigerant to flow from the heat exchange module 4 to the indoor unit 2 but does not allow reverse flow.

[0044] During heating, the outdoor unit 1 of the air conditioner directs the refrigerant from the heating outlet 100 to the heat exchange module 4, then through the second one-way valve 14 to the indoor unit 2, and finally back to the cooling outlet 101 of the outdoor unit 1. During cooling, the outdoor unit 1 directs the refrigerant directly from the cooling outlet 101 to the indoor unit 2, then from the indoor unit 2 back to the first one-way valve 13, and finally from the first one-way valve 13 back to the heating outlet 100 of the outdoor unit 1.

[0045] In another embodiment of this utility model, the valve device can also be a solenoid valve. By controlling the on and off of the solenoid valve, the utility model allows the refrigerant to pass through the heat exchange module 4 during heating, and controls the refrigerant not to pass through the heat exchange module 4 during heating, thereby avoiding the generation of condensate in the heat exchange module 4 during cooling.

[0046] In addition, other valve structures can be used in valve devices, which are well-known technologies in the valve field and will not be elaborated upon.

[0047] The working principle of this invention is as follows: In heating mode, the high-temperature gaseous refrigerant output from the outdoor unit 1 enters the water-cooled condenser 5 through the liquid distribution pipe to exchange heat with water and produce hot water. The hot water then dissipates heat through radiation and convection via the radiator 3, raising the indoor temperature. Next, the medium- and low-temperature refrigerant enters the indoor unit 2 to exchange heat with the indoor air a second time, producing medium-temperature hot air and further raising the indoor temperature. Finally, it returns to the outdoor unit 1. In cooling mode, the low-temperature liquid refrigerant output from the outdoor unit 1 enters the indoor unit 2 directly through the liquid distribution pipe, exchanges heat with the indoor air to produce cold air, and then returns directly to the outdoor unit 1.

[0048] It should be noted that there are two pipes between the outdoor unit 1 and the indoor unit 2 of the air conditioner. The first pipe transfers the refrigerant from the outdoor unit 1 to the indoor unit 2, and the second pipe transfers the refrigerant from the indoor unit 2 to the outdoor unit 1.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
