Description

Technical Field

[0001] The present invention relates to the technical field related to heat exchange equipment, and in particular to a heat exchange equipment and a control method for the heat exchange equipment. Background Art

[0002] Heat exchange equipment has the function of temperature regulation, such as air conditioners. As one of the air conditioners, through-the-wall air conditioners have a growing market. During the use of air conditioners, in the winter heating mode, the outdoor condenser will produce condensed water that slides down the fins and gathers in the chassis through heat exchange or high-temperature defrosting and ice melting. Due to usage requirements, the condensed water on the outdoor side of the through-the-wall air conditioner does not need to be installed with water pipes and is directly discharged and drips onto the ground or buildings. When the outdoor ambient temperature is below 0°, the condensed water gathered in the chassis will freeze, which may damage the high-speed running fan blades and the water rings set on the fan blades, causing the air conditioner to fail to work properly.

[0003] Although some air conditioners on the market currently have the technical effect of melting condensed water and supplying liquid to the evaporator to form steam so that the steam can achieve humidification, the amount of condensed water consumed by the steam is limited, and the problem of condensed water being unable to be processed still exists.

[0051] Embodiment 1

[0052] In order to solve the problem of incomplete condensate treatment in the heat exchange equipment in the prior art, the present invention provides a heat exchange equipment. Specifically, the heat exchange equipment is a through-the-wall air conditioner. The through-the-wall air conditioner provided by the present application does not need to discharge the condensate to the outside in real time and has a good condensate treatment function.

[0053] like Figures 1 to 5 As shown, the heat exchange device includes a shell, a partition 20, an evaporator 30, a water tank 40 and an electrical box 50. The partition 20 is arranged inside the shell, and the partition 20 divides the interior of the shell into an indoor side and an outdoor side. The shell on the outdoor side has a water collecting structure 110, and the evaporator 30, the water tank 40 and the electrical box 50 are arranged on the indoor side. The water tank 40 and the electrical box 50 are respectively located on both sides of the evaporator 30 along a first direction. The water tank 40 is connected to the water collecting structure 110 and is used to supply liquid to the evaporator 30.

[0054] Specifically, the heat exchange equipment of the present application uses a water tank 40 to collect condensed water inside the water collecting structure 110, and then stores the condensed water or supplies liquid to the evaporator 30, thereby humidifying the air while consuming the condensed water, thereby not only realizing the collection of condensed water, but also improving the secondary utilization of condensed water, avoiding the problem of condensed water overflowing the water collecting structure 110 or the condensed water being unable to be handled.

[0055] Furthermore, the heat exchange equipment of the present application provides an evaporator 30, a water tank 40 and an electrical box 50 arranged on the indoor side to prevent the water inside the water tank 40 from freezing, and adopts a means of arranging the water tank 40 and the electrical box 50 on both sides of the evaporator 30 to prevent abnormal drainage of the water tank 40 from causing condensed water to flow into the electrical box 50 and cause a safety hazard.

[0056] Furthermore, the shell has a chassis 10, and the chassis 10 has a water collecting trough. The water collecting trough is a water collecting structure 110. Condensed water is collected through the water collecting trough. The water tank 40 is connected to the water collecting trough to collect the condensed water inside the water collecting trough. Collecting condensed water through the water tank 40 has the effect of avoiding discharge of condensed water. At the same time, the water tank 40 can also provide liquid to the fins of the condenser 60 as a water supply structure to humidify the gas flowing through the fins to achieve the effect of humidifying the gas.

[0057] It should be noted that the first direction in this embodiment is the X direction shown in the figure.

[0058] Furthermore, the electrical box 50 is arranged in line with the evaporator 30 along the first direction, and the electrical box 50 is arranged at the side of the evaporator 30, which is convenient for repairing and replacing the components inside the electrical box 50. The evaporator 30 and the electrical box 50 are arranged at the end of the chassis 10 away from the outdoor side.

[0059] Furthermore, the outdoor condenser 60, the indoor evaporator 30, the electrical box 50 and the partition 20 are all arranged on the chassis 10 and located inside the shell, and at least a portion of the shell is arranged through the wall to form an indoor side and an outdoor side.

[0060] In this embodiment, the water tank 40 is disposed between the partition 20 and the evaporator 30 to facilitate positioning of the water tank 40 and also facilitate the water tank 40 to supply liquid to the evaporator 30. Specifically, the water tank 40 is connected to the side of the partition 20 facing the evaporator 30, and the water tank 40 is fixed on the partition 20 so that the water tank 40 has a higher installation position, thereby achieving a higher position of the water outlet 402 of the water tank 40, so that the liquid inside the water tank 40 can flow to the evaporator 30.

[0061] like Figures 1 to 8 As shown, the water tank 40 has a water outlet 402 , and the distance between the water outlet 402 and the bottom pan 10 is not less than the distance between the evaporator 30 and the bottom pan 10 .

[0062] Specifically, when the water outlet 402 of the water tank 40 is higher than the evaporator 30, there is no need to set up an additional water pump. Water can automatically flow to the evaporator 30 by relying on the gravity of the water, thereby reducing the use of components, which is beneficial to reducing costs, reducing noise, reducing heat generation and reducing the failure rate, thereby improving usage efficiency and user experience.

[0063] Furthermore, the water outlet 402 of the water tank 40 is connected to the evaporator 30 via a pipe.

[0064] Furthermore, the water tank 40 also has a water inlet 401 connected to the water collecting structure 110, and the distance between the water inlet 401 and the bottom plate 10 is greater than the distance between the water outlet 402 and the bottom plate 10. The height of the water inlet 401 is higher than that of the water outlet 402 to avoid water backflow.

[0065] Furthermore, the water inlet 401 and the water outlet 402 are arranged on a set of opposite side walls of the water tank 40, and the heat exchange device also includes a filter component 410, which is vertically arranged in the area between the water inlet 401 and the water outlet 402 so that the liquid entering the water inlet 401 flows to the water outlet 402 after passing through the filter component 410.

[0066] Among them, the filter component 410 includes a filter 412 and a mounting frame 411. The mounting frame 411 is arranged on the bottom surface of the inner wall of the water tank 40 and on a group of opposite sides where the water inlet 401 and the water outlet 402 are not arranged. The mounting frame 411 has a mounting groove, and the filter 412 is installed inside the mounting groove, so that the liquid inside the box flows through the filter 412 and then flows to the water outlet 402. The filter 412 will filter out impurities to prevent impurities from flowing to the indoor side and generating odor.

[0067] In this embodiment, the filter screen 412 has a cross bar 4121 and a longitudinal bar 4122 arranged crosswise. 2 The number of horizontal bars 4121 and vertical bars 4122 in the filter screen 412 is X, and 10≤X≤16. Fig. 9 As shown, when X is 13, 1cm 2 The filter screen 412 has 13 cross bars 4121 and 13 longitudinal bars 4122. When the cross bars 4121 and the longitudinal bars 4122 meet the requirement of 10-16, water can pass smoothly. If the density of the mesh material is too large, the impurities cannot be filtered thoroughly. If the density of the mesh material is too small, the water can not pass smoothly.

[0068] like Figures 1 to 10 As shown, the heat exchange device also includes a liquid conduit 420, a pump body assembly 90, a liquid level sensor, a cover plate 930 and an electric heater 940. One end of the liquid conduit 420 is connected to the water collecting tank, and the other end of the liquid conduit 420 passes through the partition 20 and is connected to the water inlet 401 of the water tank 40. The pump body assembly 90 is arranged on the chassis 10. The pump body assembly 90 includes a pump body bracket 910 and a pump body 920 arranged on the pump body bracket 910. The pump body 920 is connected to the liquid conduit 420. The pump body 920 is used to provide a driving force for the liquid to flow to the water tank 40. The liquid level sensor is arranged on the pump body bracket 910, and the cover plate 930 is arranged on the pump body 920. An installation cavity is formed between the cover plate 930 and the pump body 920. The electric heater 940 is arranged inside the installation cavity, and the electric heater 940 is arranged on one side of the liquid outlet of the pump body 920.

[0069] Specifically, the condensed water inside the water collection structure 110 flows to the water tank 40 through the liquid guide pipe 420. In order to avoid ice formation at the pump body, the electric heating element 940 is used to increase the temperature. The cover plate 930 is used to lock the electric heating element 940 and to ground it.

[0070] Furthermore, the pump body bracket 910 provides an installation space 911 for the pump body 920. By arranging the pump body 920 inside the pump body bracket 910, the effect of protecting and fixing the pump body 920 is achieved. The pump body bracket 910 is fixedly connected to the chassis 10 through fasteners.

[0071] Furthermore, a liquid level sensor is installed on the pump body support 910 to detect the liquid level inside the water collection structure 110 .

[0072] Furthermore, a humidity sensor is provided on the outdoor housing to obtain outdoor humidity.

[0073] In this embodiment, the partition 20 has a through hole 210, and the liquid guide tube 420 passes through the through hole 210. The heat exchange device also includes a seal, which is filled between the outer wall of the liquid guide tube 420 and the inner wall of the through hole 210. The through hole 210 is located at the end of the partition 20 away from the chassis 10, so that the through hole 210 and the liquid guide tube 420 in the liquid inlet area of ​​the water tank 40 are roughly flush, which facilitates the flow of liquid. At the same time, the sealing effect is achieved by filling the seal between the through hole 210 and the liquid guide tube 420. The seal can be a sponge, sealing mud, etc.

[0074] In this embodiment, the heat exchange device further includes an insulation pipe, which is sleeved on the liquid guide pipe 420, and the thickness of the pipe wall of the insulation pipe is H, 10mm≤H≤40mm. The insulation pipe is provided to prevent water from freezing and clogging in the process of flowing into the water tank 40. The diameter of the insulation pipe needs to be designed between 10-40mm to avoid the insulation pipe being too thin to achieve the insulation effect and cause the water pipe to freeze. At the same time, the insulation pipe being too thick will also cause difficulties in the assembly of the whole machine and the routing of the pipe.

[0075] like Figures 1 to 10 As shown, the heat exchange device also includes a drain valve 130 and a heating element. The water collection tank has multiple areas with different depths. A drain port is arranged on the bottom of the tank at the area with the largest depth in the water collection tank. The drain valve 130 is arranged at the drain port, and the heating element is arranged at the area with the largest depth in the water collection tank.

[0076] Specifically, multiple areas of different depths are conducive to the liquid flowing to the area with the greatest depth, thereby achieving complete discharge of the liquid. Arranging the heating element in the area with the greatest depth is conducive to achieving complete melting of the ice after the condensed water freezes.

[0077] Furthermore, by providing a drain valve 130 at the drain outlet, the drain outlet can be opened or closed by the drain valve 130. When the drain outlet is opened, the condensed water in the water collection tank can be discharged to the outside together with the rainwater. When the humidity sensor detects that it is raining outside, the drain valve 130 can be opened.

[0078] Furthermore, the heat exchange device also includes a condenser 60, a water-pumping flywheel 70 and a wind shield 120. The condenser 60 is arranged at one end of the chassis 10 away from the evaporator 30. The water-pumping flywheel 70 is connected to the chassis 10. The water-pumping flywheel 70 is arranged between the condenser 60 and the partition 20 and is located above the heating element. The water-pumping flywheel 70 includes a motor and an axial flow fan blade water-pumping ring 710. The motor is drivingly connected to the axial flow fan blade water-pumping ring 710. The axial flow fan blade water-pumping ring 710 is used to pump condensed water inside the water collection tank toward the condenser 60. The wind shield 120 is fixedly connected to the chassis 10. The wind shield 120 is arranged between the water-pumping flywheel 70 and the heating element.

[0079] The water-pumping flywheel 70 is used to pump the condensed water toward the condenser 60 , and then the condensed water is consumed by the condenser 60 . Meanwhile, the condensed water has the effect of cooling the condenser 60 .

[0080] Furthermore, the wind shield 120 is fixed to the chassis 10 by screws. The function of the wind shield 120 is to prevent the condensed water under the axial flow fan blade water circle 710 from blowing onto other components and causing them to freeze.

[0081] It should be noted that the controllable elements of the present application, such as the pump body 920, the evaporator 30, the condenser 60, the motor, the liquid level sensor, the humidity sensor, the electric heater 940, the drain valve 130 and the heating element are all controlled by a controller arranged inside the electrical box 50.

[0082] like Figures 1 to 10 As shown, the heat exchange device also includes a distributor 80 connected to the water outlet 402 of the water tank 40, the distributor 80 is arranged on the top of the evaporator 30, the distributor 80 has a liquid hole 821 for supplying liquid to the evaporator 30, and the distance between the distributor 80 and the bottom plate 10 is smaller than the distance between the water outlet 402 of the water tank 40 and the bottom plate 10.

[0083] Specifically, the height of the distributor 80 is smaller than the height of the water outlet 402 of the water tank 40 , thereby enabling the liquid inside the indoor water tank 40 to flow toward the distributor 80 , which is beneficial to improving the smoothness of the flow of the liquid.

[0084] Furthermore, by arranging a distributor 80 on the top of the evaporator 30, the condensed water can flow evenly to the fins of the evaporator 30, thereby achieving uniform humidification of the gas and improving the humidification efficiency.

[0085] Furthermore, along the first direction, the first end of the distributor 80 is connected to the water outlet 402 of the water tank 40, and the distributor 80 has a liquid trough 810, and the distance between the first end of the bottom surface of the liquid trough 810 and the chassis 10 is greater than the distance between the second end of the bottom surface of the liquid trough 810 and the chassis 10, so that the bottom surface of the trough is formed into a guide slope 820.

[0086] The condensed water flows into the liquid containing tank 810 and then flows along the guiding slope 820 . The guiding slope 820 is designed to make it easier for the condensed water to flow to the second end of the distributor 80 .

[0087] Furthermore, the angle between the guide slope 820 and the horizontal plane is A, 0.2°≤A≤5°.

[0088] Furthermore, the liquid passage hole 821 is arranged on the bottom surface of the groove, and the bottom surface of the groove has a plurality of areas arranged in sequence along the direction from the first end of the bottom surface of the groove toward the second end, each area has a liquid passage hole 821 with a different aperture, and the aperture of the liquid passage hole 821 in each area along the direction from the first end of the bottom surface of the groove toward the second end is gradually increased, so that the condensed water is evenly introduced into various parts of the evaporator 30.

[0089] In this embodiment, the diameter of the liquid hole 821 is D, 2.5 mm≤D≤3.5 mm.

[0090] like Figures 1 to 10 In the specific embodiment shown, along the direction from the first end of the bottom surface of the groove toward the second end, the bottom surface of the groove is sequentially provided with a first area, a second area, a third area, a fourth area and a fifth area, wherein the aperture of the liquid outlet of the first area is 2.5mm≤D≤2.6mm, the aperture of the liquid outlet of the second area is 2.7mm≤D≤2.8mm, the aperture of the liquid outlet of the third area is 2.9mm≤D≤3.0mm, the aperture of the liquid outlet of the fourth area is 3.1mm≤D≤3.2mm, and the aperture of the liquid outlet of the fifth area is 3.3mm≤D≤3.5mm.

[0097] The real-time liquid level information and the real-time humidity information are compared with the preset information to determine whether to start the pump assembly 90 or open the drain valve 130.

[0098] Among them, after the heat exchange device is started, a control instruction is sent to the controller through the remote control or button. After receiving the control instruction, the controller turns on the heating mode or turns off the heating mode. When the heating mode is not executed, the pump body assembly 90 is not started.

[0099] Further, comparing the real-time liquid level information and the real-time humidity information with the preset information, and determining whether to start the pump assembly 90 or to open the drain valve 130 includes:

[0100] Determine whether the real-time liquid level information is greater than the preset liquid level information. When the real-time liquid level information is not greater than the preset liquid level information, the pump assembly 90 does not start;

[0101] When the real-time liquid level information is greater than the preset liquid level information, it is determined whether the real-time humidity information is greater than the preset humidity information. When the real-time humidity information is greater than the preset humidity information, the drain valve 130 is opened and the pump body assembly 90 is not started; when the real-time humidity information is not greater than the preset humidity information, the pump body assembly 90 is started and the drain valve 130 is not opened.

[0102] In this embodiment, after the heating mode is started, the liquid level sensor obtains the real-time liquid level information of the condensed water inside the water collection structure 110. When the real-time liquid level information is less than the preset liquid level information, the pump assembly 90 is not started and the drain valve 130 is in a closed state. When the real-time liquid level information is equal to the preset liquid level information, the outdoor humidity sensor obtains the real-time humidity information outside and compares it with the preset humidity information. When the real-time humidity information is equal to the preset humidity information, it is raining outside. At this time, the drain valve 130 is opened to discharge the condensed water to the outside; when the real-time humidity information is less than the preset humidity information, the pump assembly 90 is started to pump the condensed water to the inside of the water tank 40.
