Detailed Description
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, based on the examples herein, which are within the scope of the utility model as defined by the claims, will be within the scope of the utility model as defined by the claims.
Example 1:
as shown in fig. 1, the air conditioner and water heater integrated machine provided in this embodiment includes a compressor 1, a condenser 2, an evaporator 4, a water storage unit 8, and a heat exchange unit 9, wherein:
the condenser 2 (i.e. the outdoor heat exchanger) and the evaporator 4 (i.e. the indoor heat exchanger) are respectively communicated with the compressor 1 through a first pipeline 3 and a second pipeline 5, the condenser 2 and the evaporator 4 are respectively communicated with each other through a third pipeline 6, and a first valve 7 is arranged on the third pipeline 6, and optionally, the first valve 7 is an electronic expansion valve and plays a role of throttling. The compressor 1, the condenser 2 and the evaporator 4 provided in this embodiment form a basic system of an air conditioner, and of course, the air conditioner further includes a gas-liquid separator, a subcooler, a four-way valve, an oil separator, etc., which are conventional technologies, so detailed descriptions thereof will not be repeated here. Under the refrigeration working condition, part of high-temperature and high-pressure refrigerant from the compressor 1 enters the condenser 2 through the first pipeline 3 to be condensed, the condensed refrigerant flows to the evaporator 4 through the third pipeline 6 to absorb heat and evaporate, so that the refrigerant is refrigerated outwards, the evaporated refrigerant flows back to the compressor 1 through the second pipeline 5, and the first valve 7 throttles, reduces the pressure and reduces the temperature of the refrigerant entering the evaporator 4.
The water storage unit 8 is a water storage tank, which is communicated with a water inlet pipe and a water outlet pipe, the water inlet pipe guides tap water into the water storage unit 8, and the water outlet pipe guides water in the water storage unit 8 for use. The heat exchange unit 9 is provided with a first refrigerant flow channel 10 and a water flow channel 11, and the first refrigerant flow channel 10 and the water flow channel 11 are closely arranged, so that the first refrigerant flow channel 10 and the water flow channel 11 can exchange heat. The two ends of the water channel 11 are respectively communicated with the water storage unit 8 through a fourth pipeline 12 and a fifth pipeline 13, a water pump 14 is further arranged on the fourth pipeline 12, the water pump 14 is used for pumping water in the water storage unit 8 to the fourth pipeline 12, the fourth pipeline 12 is used for guiding water into the water channel 11, and the fifth pipeline 13 is used for guiding water in the water channel 11 back to the water storage unit 8, so that a water circulation is formed. The two ends of the first refrigerant flow channel 10 are respectively communicated with the first pipeline 3 and the third pipeline 6 through a sixth pipeline 15 and a seventh pipeline 16, and a second valve 17 is arranged on the seventh pipeline 16, and optionally, the second valve 17 is an electronic expansion valve or a two-way valve.
In this way, under refrigeration condition, part of high-temperature and high-pressure refrigerant from the compressor 1 enters the condenser 2 through the first pipeline 3 to be condensed, enters the evaporator 4 through the third pipeline 6 to absorb heat and evaporate after being condensed, and finally flows back to the compressor 1 through the second pipeline 5. When the second valve 17 is opened, since the sixth pipe 15 is connected to the first pipe 3 and the seventh pipe 16 is connected to the third pipe 6, the other part of the high-temperature and high-pressure refrigerant from the compressor 1 flows into the first refrigerant passage 10 of the heat exchanging unit 9 through the sixth pipe 15, the high-temperature refrigerant in the first refrigerant passage 10 heats the water in the water passage 11, the water in the water storage unit 8 is pumped into the water passage 11 by the water pump 14, the heated water flows back to the water storage unit 8 through the fifth pipe 13, and at the same time, the refrigerant having absorbed part of heat in the first refrigerant passage 10 flows to the third pipe 6 through the seventh pipe 16 and merges with the refrigerant from the condenser 2 and flows into the evaporator 4 for evaporation. When the second valve 17 is closed, a small portion of the high-temperature and high-pressure refrigerant from the compressor 1 will enter the first refrigerant flow channel 10 through the sixth pipeline 15, but since the seventh pipeline 16 is disconnected by the second valve 17, a large amount of the high-temperature and high-pressure refrigerant will not enter the first refrigerant flow channel 10, and at this time, the air conditioning system composed of the compressor 1, the condenser 2 and the evaporator 4 is a conventional air conditioner.
When the air conditioner is specifically used, if a user needs hot water, the water pump 14 is started, if the air conditioner runs in a refrigerating mode, the compressor 1 is directly started to run, the second valve 17 on the seventh pipeline 16 is opened, and part of high-temperature refrigerant discharged by the compressor 1 bypasses the first refrigerant flow passage 10 to exchange heat with water in the water flow passage 11, so that circulating water is heated. When the hot water demand ceases, the second valve 17 is closed, the water pump 14 is turned off, and the compressor 1 is turned off. When the compressor 1 is not started in the state of stopping or waiting of the air conditioner, the air conditioner is started to perform refrigeration operation, then the second valve 17 and the water pump 14 on the second pipeline 5 are opened, and part of the high-temperature refrigerant discharged by the compressor 1 is bypassed to the first refrigerant flow passage 10 to perform heat exchange with water in the water flow passage 11, so that the circulating water is heated. When the hot water demand ceases, the second valve 17 is closed, the water pump 14 is turned off, and the compressor 1 is turned off.
Through the above-mentioned structure, the air conditioner and water heater all-in-one that this embodiment provided not only can provide the function of refrigeration, but also can heat the water in the water storage unit 8, plays the function of water heater. The user only needs to control the opening and closing of the second valve 17. Specifically, when it is necessary to heat the water in the water storage unit 8, the second valve 17 is opened, the water pump 14 is turned on, and the air conditioner is turned to the cooling mode. When the water in the water storage unit 8 is not required to be heated, the second valve 17 is closed, and the circulation system consisting of the compressor 1, the condenser 2 and the evaporator 4 is a common air conditioning system. Therefore, the air conditioner and water heater integrated machine provided by the embodiment can heat domestic water by utilizing the heat of the refrigerant before part of the refrigerant enters the evaporator 4 by means of the heat exchange unit 9, so that the practicability is higher, and the overall cost is cheaper than that of the multi-split water connection water heater.
More preferably, on-off valves are provided in each of the sixth pipe 15 and the seventh pipe 16, and when hot water is not used, the on-off valves in the sixth pipe 15 and the seventh pipe 16 may be closed.
Of course, the water storage unit 8 (i.e., the water storage tank) is provided with an electric heating system, and the second valve 17 is closed under heating or other conditions, so that the air conditioner can be used normally, and at this time, the water in the water storage unit 8 is heated by the electric heating system.
Alternatively, the heat exchange unit 9 in the present embodiment is a plate heat exchanger or a double pipe heat exchanger.
Optionally, in this embodiment, a position where the seventh pipeline 16 is connected to the third pipeline 6 is a node, and the node is located between the condenser 2 and the first valve 7, so that the refrigerant coming out of the condenser 2 and the refrigerant coming out of the first refrigerant flow channel 10 are converged in the third pipeline 6, and then the converged refrigerant is throttled, depressurized and cooled by the first valve 7, so as to ensure that the refrigerant entering the evaporator 4 under the refrigeration working condition is the refrigerant throttled, depressurized and depressurized by the first valve 7, and further ensure the evaporation and heat absorption effects of the refrigerant at the evaporator 4.
An alternative implementation of this embodiment is as follows: as shown in fig. 1, the air conditioner and water heater integrated machine provided in this embodiment further includes a heat dissipation module 18, a second refrigerant flow channel is provided in the heat dissipation module 18, and the second refrigerant flow channel is connected in series in the third pipeline 6 through a pipeline, so that the refrigerant in the third pipeline 6 will enter the second refrigerant flow channel of the heat dissipation module 18, and the heat dissipation module 18 is attached to the controller of the air conditioner to dissipate heat of the controller motherboard. When the air conditioner operates, a large amount of heat can be generated by a main board in the air conditioner controller, and the controller mainly dissipates heat through air cooling in a high-temperature environment, so that the heat dissipation effect is poor. In the air conditioner and water heater integrated machine provided by the embodiment, part of heat of the controller is taken away by the refrigerant flowing in the heat dissipation module 18, so that the heat dissipation effect of the controller is better.
Optionally, the heat dissipation module 18 in this embodiment is disposed between the condenser 2 and the node in a communicating manner, so that the refrigerant coming out of the condenser 2 is utilized to dissipate heat of the controller, and the temperature is more moderate. If the cooling medium throttled by the first valve 7 is used for cooling the controller, the cooling medium throttled by the first valve 7 is easy to condense on the controller and the main board because the temperature of the cooling medium is very low. Therefore, the cooling medium from the condenser 2 is led into the heat dissipation module 18 to dissipate heat of the controller and the motherboard, so that the risk of condensation burning on the motherboard can be effectively reduced.
An alternative implementation of this embodiment is as follows: as shown in fig. 1, the fourth pipe 12, the fifth pipe 13, the sixth pipe 15 and the seventh pipe 16 are each provided with a bulb 19, and the bulbs 19 are located close to the heat exchange unit 9, so that the bulbs 19 on the fourth pipe 12 can detect the temperature of water entering the water flow path 11, the bulbs 19 on the fifth pipe 13 can detect the temperature of water exiting the water flow path 11, the bulbs 19 on the sixth pipe 15 can detect the temperature of refrigerant entering the first refrigerant flow path 10, and the bulbs 19 on the seventh pipe 16 can detect the temperature of refrigerant exiting the first refrigerant flow path 10.
An alternative implementation of this embodiment is as follows: as shown in fig. 1, a water flow switch 20 for controlling on/off is further provided on the fourth pipe 12, and the water flow switch 20 is located upstream of the water pump 14. The water flow switch 20 is used for controlling the fourth pipeline 12 to be turned on or off, and in the normal case, the water flow switch 20 is turned on, and in the case that the water pump 14 needs to be removed or the water pump 14 fails, the water flow switch 20 is turned off, so that the water pump 14 is removed for maintenance or replacement.
The fourth pipe 12 is further provided with an expansion tank 21 in communication therewith, the expansion tank 21 being located upstream of the water flow switch 20. By means of this expansion tank 21, the expansion of the water in the fourth line 12, the fifth line 13, the water flow channel 11 and the water storage unit 8 can be accommodated, while also acting as a constant pressure and as a water replenishment.
The fifth pipe 13 is provided with a relief valve 22, and when the water pressure in the water circulation system constituted by the fourth pipe 12, the fifth pipe 13, the water flow passage 11, and the water storage unit 8 is high, the relief valve 22 is operated to reduce the pressure of the water in the water circulation system. An exhaust valve 23 is also provided in the fifth pipe 13 to facilitate the exhaust of the gas in the water circulation system.
The above description is merely an embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present utility model, and it is intended to cover the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
