Detailed Description
In order to make the technical field person understand the scheme of the present invention better, the following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical scheme in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of some, and not necessarily all, embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by the skilled person without creative work belong to the protection scope of the present invention.
The technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
There are several ways to improve the heat exchange effect of a heat exchanger. For example by lowering the temperature of the air. And the second mode is to increase the output of a condensing fan in the system. The third mode is to enlarge the heat exchanger, so that the air can exchange heat more fully in the heat exchanger. However, the above method either increases energy consumption or consumes more precious copper and aluminum resources, and is not in line with the current policy of carbon neutralization and carbon peak-reaching.
The air conditioning unit of the related art generally installs the wet film outside the heat exchanger, and the air cooling is carried out through the heat absorption of water evaporation, and the air after the wet film cooling exchanges heat with the heat exchanger again to improve the heat exchange efficiency of heat exchanger. However, the evaporation efficiency effect of the wet film arranged outside the heat exchanger is influenced by the relative humidity of the environment, and under the condition that the relative humidity of return air is high, the heat exchange efficiency of the wet film is reduced, and the heat exchange efficiency of the heat exchanger is also reduced. The evaporation capacity accounts for the proportion of the circulation capacity in the use process of the wet film and is small, a large amount of water is repeatedly circulated through the water pump, the energy is wasted, meanwhile, the circulating water is scattered or evaporated and lost in the circulation process, and the latent heat of evaporation cannot be fully and efficiently utilized in single circulation.
Referring to fig. 1, an embodiment of the present invention provides an air conditioning unit 10, for example, the air conditioning unit 10 may be an air conditioner in a machine room, and the air conditioning unit 10 may refrigerate to provide a certain amount of cooling capacity to the machine room, so as to help ensure that the machine room is maintained in a proper temperature environment.
In this embodiment, the air conditioning unit 10 includes the air conditioning heat exchange module 11 and the unit casing 12, and the air conditioning heat exchange module 11 is disposed in the unit casing 11, so that the unit casing 11 can provide certain support and protection for the air conditioning heat exchange module 11, and helps to prevent the devices inside the air conditioning unit 10 from being damaged.
In this embodiment, the air-conditioning heat exchange module 11 may be used as a condensing module, for example, the air-conditioning heat exchange module 11 may be installed outside the room, the air-conditioning heat exchange module 11 may satisfy the heat exchange of the outdoor air, and finally, the hot air after heat exchange by the air-conditioning heat exchange module 11 is directly discharged to the outside of the room.
Specifically, the air conditioning heat exchange module 11 includes a first heat exchanger 111, a second heat exchanger 112, a first wet film 113 and a water distributor 114, the first wet film 113 may cool air flowing through the first wet film 113, and both the first heat exchanger 111 and the second heat exchanger 112 may satisfy heat exchange of air in the air conditioning unit 10. The first heat exchanger 111 has a first air inlet side 1111 and a first air outlet side 1112 which are opposite to each other, the second heat exchanger 112 has a second air inlet side 1121 and a second air outlet side 1122 which are opposite to each other, and the second air inlet side 1121 is opposite to the first air outlet side 1112, so that the hot air can firstly exchange heat with the first heat exchanger 111, then enters the second heat exchanger 112 through the second air inlet side 1121 to exchange heat with the second heat exchanger 112, and finally flows out of the air-conditioning heat exchange module 11 through the second air outlet side 1122. The medium flowing through the first heat exchanger 111 and the second heat exchanger 112 is high-temperature and high-pressure steam. The direction indicated by the dashed arrow in fig. 1 is the flow direction of the airflow.
The first wet film 113 is disposed between the first air outlet side 1112 and the second air inlet side 1121, which is helpful for improving the heat exchange efficiency of the air-conditioning heat exchange module 11 and also helps to reduce the temperature of the hot air at the outlet of the air-conditioning heat exchange module 11.
Specifically, when the air conditioning unit 10 is in operation, the high-temperature and high-pressure vapor in the first heat exchanger 111 is liquefied to release heat, and at this time, the hot air in the air conditioning unit 10 exchanges heat with the first heat exchanger 111, and the temperature of the hot air rises. Because the water on the first wet film 113 evaporates to absorb heat, partial heat can be taken away when the hot air after heat exchange through the first heat exchanger 111 flows through the first wet film 113, the temperature of the hot air is reduced at the moment, and the temperature of the cooled hot air is lower than that of the initial hot air, so that the temperature difference between the inner side and the outer side of the second heat exchanger 112 can be increased, the heat exchange efficiency of the second heat exchanger 112 can be improved, and the utilization rate of the water can be improved. When the high-temperature high-pressure steam in the second heat exchanger 112 is liquefied and releases heat, the hot air cooled by the first wet film 113 exchanges heat with the second heat exchanger 112, so that after heat exchange by the air-conditioning heat exchange module 11, the temperature of the hot air at the outlet of the air-conditioning heat exchange module 11 is reduced compared with the temperature of the hot air at the outlet of the conventional heat exchange module 11 after heat exchange, thereby being beneficial to reducing the condensation pressure of the air-conditioning unit 10 and reducing the power consumption of the compressor, and further improving the energy efficiency of the air-conditioning unit 10.
Since the first wet film 113 has a poor cooling effect under the condition of high relative humidity, when the hot air flows through the first wet film 113, the hot air absorbs heat through the first heat exchanger 111, the temperature rises, the moisture content of the hot air is not changed, and the relative humidity drops, so that the evaporation of water on the first wet film 113 is facilitated to be more sufficient by reducing the relative humidity of the hot air, and the humidification amount in the humidification process can also be increased. Therefore, the evaporation capacity of the circulating water passing through the air conditioner heat exchange module 11 once is increased, and the power consumption of the circulating water in the repeated and continuous circulating process is reduced, so that the utilization rate of the water is improved. In the process, the first wet film 113 can bring more sensible heat, which is beneficial to better cooling the hot air flowing through the first wet film 113, so that the inner side and the outer side of the second heat exchanger 112 obtain larger heat exchange temperature difference, thereby being beneficial to improving the heat exchange efficiency of the second heat exchanger 112.
In addition, the first wet film 113 is easily contaminated by organisms and accumulated with dust, and the first wet film 113 is disposed between the first air outlet side 1112 and the second air inlet side 1121, so that the irradiation of sunlight to the first wet film 113 is reduced, the first wet film 113 is prevented from breeding mold and algae, and meanwhile, the material of the first wet film 113 is prevented from aging, so that the service life of the first wet film 113 is prolonged. In this way, the degree of environmental impact on the use of the first wet film 113 is reduced, which contributes to better improving the heat exchange efficiency of the air exchange thermal module 11, thereby contributing to energy saving of the air conditioning unit 10.
The water distributor 114 is used for supplying water to the first wet film 113, which helps to ensure the wettability of the first wet film 113 and better improve the heat exchange efficiency of the air exchange thermal module 11. The water distributor 114 is located above the first wet film 113, so that the water distributor 114 is helped to rapidly supply water into the first wet film 113 to meet the water demand of the first wet film 113.
The water distributor 114 is provided with a plurality of water outlet holes (not shown), and the water outlet holes are arranged at equal intervals. For example, the water distributor 114 may be designed with one or more rows of outlet holes, and the distance between every two outlet holes in each row of outlet holes is approximately 0.5mm, which helps the water distributor 114 to provide a proper amount of water to the first wet film 113, and also ensures the uniformity of the outlet water of the water distributor 114. The water outlet hole diameter of the water distributor 114 is large, the resistance is small, water can be directly distributed by the water distributor 114 without adding a water pump, and therefore the air-conditioning heat exchange module 11 can be conveniently manufactured.
The air conditioning heat exchange module 11 has high evaporation efficiency, and the water distributor 114 is used for controlling a proper amount of water supply, so that the water spraying amount and the evaporation amount of the air conditioning unit 10 are kept consistent approximately, no circulating water is realized, the power of an extra circulating water pump is reduced, and the air conditioning unit 10 is more efficient and energy-saving.
It should be noted that, in some embodiments, the water distributor 114 may also spray water for the first heat exchanger 111 and the second heat exchanger 112, and at this time, nozzles are disposed at a plurality of water outlets of the water distributor 114, so that water in the water distributor 114 can be uniformly sprayed onto the first heat exchanger 111 and the second heat exchanger 112, which is beneficial to better heat exchange of the first heat exchanger 111 and the second heat exchanger 112.
In some embodiments, as shown in fig. 2, the air-conditioning heat exchange module 11 further includes a third heat exchanger 115 and a second wet film 116, the third heat exchanger 115 has a third air inlet side 1151 and a third air outlet side 1152 which are opposite to each other, and the third air inlet side 1151 is opposite to the second air outlet side 1122, so that the hot air may firstly exchange heat with the first heat exchanger 111, then enter the second heat exchanger 112 to exchange heat with the second heat exchanger 112, finally enter the third heat exchanger 115 through the third air inlet side 1151 to exchange heat with the third heat exchanger 115, and then exit the air-conditioning heat exchange module 11 through the third air outlet side 1152. The direction indicated by the dashed arrow in fig. 2 is the flow direction of the air flow.
The second wet film 116 is disposed between the second air outlet side 1122 and the third air inlet side 1151, so as to improve the heat exchange efficiency of the air-conditioning heat exchange module 11, and simultaneously, to reduce the temperature of the hot air at the outlet of the air-conditioning heat exchange module 11.
Specifically, when the air conditioning unit 10 is in operation, because water on the second wet film 116 evaporates to absorb heat, a part of heat will be taken away when the hot air after heat exchange by the second heat exchanger 112 flows through the second wet film 116, the temperature of the hot air is reduced at this time, and the temperature of the cooled hot air is lower than the temperature of the original hot air, which is helpful for increasing the temperature difference between the inside and the outside of the third heat exchanger 115, thereby improving the heat exchange efficiency of the third heat exchanger 115, and also helpful for improving the water utilization rate. When the high-temperature high-pressure vapor in the third heat exchanger 115 is liquefied and releases heat, the hot air cooled by the second wet film 116 exchanges heat with the third heat exchanger 115 again, so that the temperature of the hot air at the outlet is reduced after the heat exchange of the air-conditioning heat exchange module 11, the condensation pressure of the air-conditioning unit 10 is reduced, the power consumption of the compressor is reduced, and the energy efficiency of the air-conditioning unit 10 is improved.
In this embodiment, the unit housing 12 includes a side wall 121, and the air-conditioning heat exchange module 11 is obliquely disposed in the unit housing 12 relative to the side wall 121, so as to contribute to increasing the heat exchange area of the air-conditioning heat exchange module 11, and contribute to improving the heat exchange capacity of the air-conditioning heat exchange module 11. The "inclination" refers to an included angle between the air conditioner heat exchange module 11 and the side wall 121, and the included angle between the two is 30 degrees to 60 degrees, for example, the included angle may be any one of 30 degrees, 40 degrees, 50 degrees, 60 degrees, or 30 degrees to 60 degrees.
In this embodiment, the air conditioning unit 10 may include two air conditioning heat exchange modules 11, and the two air conditioning heat exchange modules 11 are symmetrically distributed. Specifically, two air conditioner heat exchange modules 11 are approximately symmetrically distributed along the central axis of air conditioning unit 10, and two air conditioner heat exchange modules 11 are all obliquely arranged in unit housing 12 relative to side wall 121, so, two air conditioner heat exchange modules 11 help to ensure that the air in air conditioning unit 10 exchanges heat with heat exchange modules 11 more fully.
The unit housing 12 may further include a top wall 122 and a bottom wall 123, the side wall 121 is connected to the top wall 122 and the bottom wall 123, and the distance between the two air conditioning heat exchange modules 11 increases from the bottom wall 123 to the top wall 122, for example, the two air conditioning heat exchange modules 11 may be substantially arranged in a "V" shape, which helps to increase the heat exchange area of the air conditioning unit 10, so as to improve the energy efficiency of the air conditioning unit 10.
In some embodiments, the air conditioning unit 10 may also only include one air conditioning heat exchange module 11, and one air conditioning heat exchange module 11 is obliquely disposed in the unit housing 12, for example, one air conditioning heat exchange module 11 may be disposed substantially in a shape of a Chinese character 'yi', and a distance between one air conditioning heat exchange module 11 and the side wall 121 decreases from the bottom wall 123 to the top wall 122, so that the oblique disposition of one air conditioning heat exchange module 11 may increase a heat exchange area of the air conditioning heat exchange module 11, which is helpful for increasing a heat exchange capability of the air conditioning heat exchange module 11, and at the same time, is helpful for saving a manufacturing cost.
The air conditioning assembly 10 further includes a fan 13, the fan 13 is located on a side of the air conditioning heat exchange module 11 departing from the first air inlet side 1111, and the fan 13 is configured to drive the airflow to flow from the first air inlet side 1111 toward the first air outlet side 1112, so as to help ensure uniformity of the inlet air of the fan 13.
In this embodiment, the fan 13 may be disposed at a V-shaped opening of the air-conditioning heat exchange module 11, so as to help ensure uniformity of air intake of the fan 13. The fan 13 may be a suction type fan, and thus, the fan 13 may pump the hot air converted by the air conditioner heat exchange module 11 to the outside. Because the first wet film 113 is at low relative humidity, and the evaporation efficiency is high, the first wet film 113 is disposed between the first air outlet side 1112 and the second air inlet side 1121, which is helpful for improving heat taken away by the first wet film 113 in the heat exchange process, so as to help reduce the fan power consumption of the fan 13 and improve the energy efficiency of the air conditioning unit 10.
