Description

Technical Field

[0001] The utility model relates to industrial air-conditioning equipment, in particular to an evaporative refrigeration air-conditioning outdoor unit with a descaling function. Background Art

[0002] Industrial plants are large in area and have a large transparent area. In order to improve working conditions in summer, they often use cooling solutions. Currently, there are two types of cooling technologies. One is central air conditioning, which is expensive and not suitable for small businesses. The other is industrial evaporative refrigeration air conditioning, which has a simple structure and low cost. Currently, most small and micro-enterprise plants use this technology.

[0003] Industrial evaporative refrigeration air conditioners generally have two parts, one is the indoor unit and the other is the outdoor unit. The principle of the indoor unit is the same as that of the indoor unit of a household air conditioner, providing a cooling function for the room. While cooling, the compressor will generate high temperature. The outdoor unit cools the compressor to ensure the normal operation of the air conditioner. The cooling principle of the outdoor unit of the evaporative refrigeration air conditioner is as follows: the outdoor unit has a water storage device and an evaporation component. Tap water is added to the water storage device, and the water in the water storage device is cooled by the evaporation device. Then, the cooled water is introduced into the compressor to cool the compressor. Thereby, the normal operation of the entire system is achieved. However, in actual use, it is found that evaporative refrigeration air conditioners have the problem of scale formation in the water pipes, thereby reducing the cooling effect on the compressor. Especially in the central or western regions, because the water contains more minerals, and the technical solution adopted by the evaporative refrigeration air conditioner is to use water vaporization to evaporate and cool down, which further increases the concentration of minerals, resulting in the evaporative refrigeration air conditioner. Efficiency is easily reduced or failure. Therefore, it is necessary to regularly replace the water pipes or descale the water pipes, resulting in increased costs and labor waste.

[0004] Therefore, a technical solution is needed to solve this problem, to facilitate the problem of scaling in water, and to facilitate the management and maintenance of equipment. Summary of the invention

[0005] The purpose of the utility model is to solve the above defects, provide an evaporative refrigeration air-conditioning outdoor unit with a descaling function, and set a descaling technical solution inside the outdoor unit to solve the problem of scale formation inside the air-conditioning pipe.

[0006] The purpose of the utility model is achieved by the following methods:

[0007] An evaporative refrigeration air-conditioning outdoor unit with a descaling function includes a frame and a water pan arranged under the frame, a bottom leakage hole is arranged at the bottom of the water pan, a descaling box is arranged on the water pan, a lock is arranged on the descaling box, and the descaling box is movably buckled with the edge of the water pan, and a water exchange hole in the form of a through hole is arranged on the outer edge of the descaling box, and the water in the water pan can communicate with the inside of the descaling box through the water exchange hole. By setting the descaling box, a slow-release solid descaling agent is placed inside the descaling box. When the water level of the cooling water in the water pan is higher than the water exchange hole, the descaling agent will dissolve and enter the water pan. When the cooling water in the water pan is pumped into the indoor unit and cools the indoor unit, the pipes will be descaled, thereby improving the cooling effect. When the water level of the water pan is lower than the water exchange hole, the descaling agent inside the descaling box will not continue to dissolve, thereby extending the use effect, and the descaling agent will be dissolved again when new water is injected into the water pan next time. This technical solution can effectively reduce the scale inside the air conditioner. At the same time, the design can greatly extend the service life of the descaling agent and is easy to replace. The built-in design can ensure aesthetics while ensuring that the descaling agent will not be contaminated by external debris.

[0008] In the above description, as a preferred solution, the descaling box is a fan-shaped cavity structure, the water tray is a square structure, and the descaling box is arranged at the corner of the water tray.

[0009] In the above description, as a preferred solution, the water exchange hole is arranged on the fan-shaped arc surface of the descaling box and is between 10-20 cm higher than the bottom surface of the descaling box.

[0010] In the above description, as a preferred solution, the water change hole is set on the fan-shaped arc surface of the descaling box and is between 10-20 cm higher than the bottom surface of the descaling box. The purpose of setting the water change hole at a high position is to save the amount of descaling agent. Because each time a certain amount of descaling agent is added to the water tray, the problem of scale can be solved and the scale in the tap water can be prevented from condensing. After each new tap water is added, more descaling agent needs to be dissolved in the water to ensure that the content of the descaling agent meets the requirements. Therefore, each time the external tap water is added, the water surface of the water tray should be higher than the bottom surface of the descaling box and reach the position of the water change hole, so that the descaling agent in the descaling box can be integrated into the water and enter the water tray. In order to avoid the descaling agent being immersed in the water for a long time, resulting in waste, the water change hole is set higher than the bottom surface. When the water is in the circulation process, it naturally evaporates, causing the water surface of the water tray to naturally decrease. When its height is lower than the water change hole, the descaling agent inside the descaling box will no longer be integrated into the circulating water of the water tray (because it already contains enough descaling agent). While reducing costs, the descaling effect can also be maintained.

[0011] In the above description, as a preferred solution, the water exchange holes are arranged in three rows in the vertical direction. The purpose of the multiple rows is to be suitable for different water qualities, power usage and volatilization speeds, and the water inflow can be adjusted as needed to flood the water exchange holes at different heights, thereby controlling the integration time and amount of the descaling agent.

[0012] In the above description, as a preferred solution, a water inlet pipe, a drain outlet, a return pipe and a water outlet pipe are provided in the water pan. The water inlet pipe is used to introduce external tap water to make up for the water lost by the outdoor unit during operation. The drain outlet is used to discharge contaminated water, because the outdoor unit has been placed outdoors, which easily causes dust and other dirty objects to mix into the water. In order to ensure the cleanliness of the water quality, the sewage can be emptied regularly and replaced with new water. The water outlet pipe is used to introduce water containing a descaling agent and cooled into the indoor unit of the air conditioner to cool the indoor unit. The return pipe is used to lead the water that has passed through the indoor unit back to the outdoor unit for recycling.

[0013] In the above description, as a preferred solution, an upper water pipe is provided above the water tray to pump the water in the water tray to the top of the rack, an exhaust fan is also provided on the rack, and a water pump is provided at the bottom of the rack.

[0014] In the above description, as a preferred solution, a spray pipe is arranged around the top of the frame, and a spray hole is arranged below the spray pipe.

[0015] In the above description, as a preferred solution, an evaporation plate is provided on the side of the frame to increase the area of ​​water and improve the evaporation rate.

[0016] In the above description, as a preferred solution, the evaporation plate is a honeycomb structure, the evaporation plate is made of a multi-layer corrugated plant fiber laminate, and a filter screen is provided on the outer side thereof.

[0017] In the above description, as a preferred solution, the water tray is provided with a sedimentation tank, and the sedimentation tank is arranged below the descaling box.

[0018] The beneficial effects of the utility model are as follows: in order to avoid the defects of the prior art, the design scheme can effectively reduce the scale inside the air conditioner. At the same time, the design scheme can greatly extend the service life of the descaling agent and is easy to replace. The built-in design can ensure aesthetics while also ensuring that the descaling agent will not be contaminated by external debris. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The purpose of the utility model is achieved by the following methods:

[0031] Industrial evaporative refrigeration air conditioners are generally composed of an outdoor unit, an indoor unit and a compressor. The indoor unit is used to refrigerate the interior of the factory, the compressor generates a cold source for the indoor unit, and the outdoor unit is used to cool the compressor so that the compressor can continue to work normally. Because the indoor unit and the compressor are conventional existing mature technologies, their refrigeration principles and technical solutions are not described in detail here.

[0032] This specification focuses on the detailed introduction of the evaporative refrigeration air conditioner outdoor unit with descaling function, which includes a frame 1 and a water tray 101 arranged below the frame 1. The water tray 101 is a square concave container structure. A detachable descaling box 5 is arranged at the corner of the water tray 101. The descaling box 5 is a fan-shaped cavity structure. A lock is arranged on the descaling box 5, which is movably buckled with the edge of the water tray 101. A water exchange hole 502 in the form of a through hole is arranged on the outer edge of the descaling box 5. The water exchange hole 502 is arranged on the fan-shaped arc surface of the descaling box 5 and is between 10-20 cm higher than the bottom surface of the descaling box 5. The water exchange holes 502 are arranged in three rows along the vertical direction.

[0033] A honeycomb evaporation plate 8 is arranged around the frame 1. The evaporation plate 8 is made of a multi-layer corrugated plant fiber laminate, wherein the multi-layer corrugated plant fiber laminate is an existing material. In the relevant e-commerce platform, input: industrial air conditioning evaporation plate (multi-layer corrugated plant fiber laminate) to obtain detailed information. When water flows through the evaporation plate 8, the contact area between water and air will increase, thereby causing the evaporation area of ​​water to increase accordingly. This is conducive to the evaporation of water. Therefore, when water passes through the surface of the evaporation plate 8, the evaporation of water causes heat to be taken away, thereby reducing the temperature of the evaporation plate 8 and the water flowing through the evaporation plate 8. In order to ensure the cleanliness of the evaporation plate 8 and reduce the purpose of being contaminated by dust and dirt, a filter screen 9 is arranged on its outer side to filter dust. At the same time, a louver plate 10 is arranged on the outer layer of the filter screen 9, so that the cleanliness of the filter screen 9 can be observed easily, and at the same time, it can prevent direct exposure to ultraviolet rays and prevent the internal parts of the external machine from aging quickly.

[0034] A drain port 102 is provided at the bottom of the water pan 101, and a water inlet pipe 3, a water return pipe 11 and a water outlet pipe 4 are provided on its side. The water inlet pipe 3 is used to introduce new tap water, the water return pipe 11 is used to circulate the water that has passed through the compressor into the water return pan 101, and the water outlet pipe 4 is used to transport the water that has passed through the evaporation plate 8 and has been cooled to the compressor again, so as to cool the compressor. The drain port 102 is used to drain all the old water in the water pan 101 at one time when maintaining the external unit. A controller 12 is provided at one end of the water inlet pipe 3, which is used to monitor the water level of the water pan 101 and control the switch of the water inlet pipe 3. When the water level is lower than the set minimum water level, tap water is injected into the water pan 101. When the water level is higher than the set maximum water level, water injection is stopped. The controller 12 may adopt a ball valve type water level control force (similar to the control principle of a flush toilet), or may adopt a combination of an electronic liquid level sensor and a solenoid valve to control the water level height (this is a conventional design and will not be described in detail here) and other technical solutions.

[0035] An upper water pipe 6 is provided above the water tray 101, one end of the upper water pipe 6 is connected to the water tray 101, and is used to pump water in the water tray 101 to the top of the frame 1. A spray pipe 7 is arranged around the top of the frame 1, and the spray pipe 7 is connected to the other end of the upper water pipe 6. A spray hole 701 is provided below the spray pipe 7, and the spray hole 701 is directly opposite to the top of the evaporation plate 8. A water pump is also provided at the bottom of the frame 1, which is used to pump water from the water tray 101 upward and transport it to the spray pipe 7.

[0036] An exhaust fan 2 is also provided on the frame to discharge the evaporated water inside the external machine into the external air in time, thereby improving the evaporation efficiency.

[0037] The working principle of the outdoor unit is as follows: When used for the first time, add tap water to the water pan 101. When the water reaches the set maximum water level, stop the water intake. Low-temperature water is delivered to the compressor through the outlet pipe 4 to cool the compressor. After the low-temperature water passes through the compressor, it takes away the heat of the compressor and becomes high-temperature water. The high-temperature water returns to the water pan 101 through the return pipe 11. At this time, the temperature of the water in the water pan 101 will also rise at the same time. At this time, the water pump also starts to work to pump the water in the water pan 101 into the upper water pipe 6 and transport it to the spray pipe 7 at the top. The lower end of the spray pipe 7 is provided with a spray hole 701, through which the water falls to the top of the evaporation plate 8. Then it flows naturally downward along the evaporation plate 8. During the flow, the water will evaporate naturally and take away the heat, so that the temperature of the evaporation plate 8 and the water flowing through the evaporation plate 8 is reduced. It flows into the water pan 101 again. Thereby, the temperature of the water in the water pan 101 is reduced, and the cooled water is transported to the compressor again to cool the compressor. A complete cycle is formed. When the water evaporates, it will cause water loss. When the water level drops to the set minimum water level, the controller 12 opens the water inlet pipe 3 and replenishes water to the water tray 101 again. When the water level reaches the set maximum water level, the water injection is stopped.

[0038] From the above working principle, we can know that in the Midwest, if the tap water contains more minerals (such as magnesium, calcium, potassium, etc.), it is very easy to form scale. When the water is continuously evaporated, the mineral content is further increased, which makes it easier to form scale. When the scale is combined with the inner wall of the pipe, it will greatly reduce the work efficiency and cause damage to the product.

[0039] The descaling box 5 is composed of a fan-shaped box body 501 and a box cover 504 arranged on the top. A buckle 503 is arranged on the side of the box body 501 for buckling with the side of the frame 1. It is detachably arranged above the water tray 101. The box cover 504 and the box body 501 are respectively provided with a latch 506 and a pin hole 505, so that the box cover 504 can be opened and closed in a rotating manner. After opening the box cover 504, a solid slow-release descaling agent (mainly composed of weakly acidic substances) is placed in the box body 501. When tap water is injected into the water tray 101, the water surface overflows the water exchange hole 502 and enters the descaling box 5, and begins to dissolve the descaling agent. The water containing the descaling agent penetrates from the inside of the box body 501 into the water tray 101. Thereby, the minerals in the water and the water containing the descaling agent produce a chemical reaction (so that the minerals exist in the state of ions, the principle is a complex reaction), so that it cannot condense on the inner wall of the pipeline. When the water level drops below the water exchange hole 502, the descaling agent in the descaling box 5 will not continue to exchange with the water in the water tray 101 (because at this time there is enough descaling agent dissolved in the tap water, and too much dissolution will cause unnecessary waste). When new tap water is injected, the water level in the water tray 101 rises again, and after it is higher than the position of the water exchange hole 502, it will dissolve and mix with the descaling agent again, and the minerals in the newly injected water will be processed, so that the circulating water in the entire outdoor unit is always kept in a non-scaling state.

[0040] At the same time, in order to adapt to different regions and different water evaporation amounts, one or several rows of water exchange holes 502 and the water level relationship between the water exchange holes 502 and the water tray 101 can be set accordingly to control the dissolution concentration and dissolution time of the descaling agent. For example, in areas with small evaporation amounts or good water quality, the water level of the water tray 101 is set lower, and only communicates with the bottom row of water exchange holes 502, so that a small amount of dissolved descaling agent can achieve the purpose of softening tap water. If the evaporation amount is large, or the water quality is poor (containing a high concentration of minerals), the water level of the water tray 101 is set at the top row of water exchange holes 502 to achieve long-term dissolution and water exchange. This technical solution is flexible and can save descaling agents while preventing pipe scaling.

[0041] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as the protection scope of the present invention.
