Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning technology, and specifically to a water spray device that improves the heat dissipation efficiency of a condenser by lowering the ambient temperature. Background Technology

[0002] An air-cooled condenser is an essential component that uses ambient air as a cold source to exchange heat with the high-temperature gaseous (above 70°C) refrigerant in the coil, causing the refrigerant to release heat and undergo a phase change to transform into a high-temperature (below 40°C) liquid refrigerant.

[0003] The main problems with existing air-cooled condensers are: 1) Since the cooling capacity of the refrigerant is related to the difference between its condensation temperature and the air temperature (referred to as the cooling temperature difference), the higher the air temperature, the smaller the cooling temperature difference, and the lower the cooling capacity. 2) When the cooling temperature difference is less than a certain value, the compressor must stop running, causing the air conditioner to become unusable.

[0004] The aforementioned problems reduce the cooling efficiency of air conditioners, increase operating and maintenance costs, and in severe cases may even cause the compressor to burn out, further exacerbating the maintenance costs of air conditioners.

[0005] In addition, existing conventional air conditioners operate at a temperature not exceeding 35℃ in their high-efficiency zone, and the maximum permissible ambient temperature does not exceed 42℃. This makes it difficult for many conventional air conditioners installed in poorly ventilated, directly exposed, or locally hot locations to meet usage requirements in hot weather, resulting in actual cooling capacity falling far short of expectations during the hot season.

[0006] Patent No. 202020161487.2 discloses an air conditioner condenser spray device, including a tray, support pillars, a water outlet pipe, a water tank, a pump body, a solenoid valve, a spiral coil, nozzles, and a water inlet pipe. The spiral coil is vertically arranged above the tray. Multiple support pillars, evenly distributed along the circumference, are fixed to the outer side of the lower end of the spiral coil. The lower end of each support pillar is fixed to the bottom surface of the tray. Multiple horizontally distributed nozzles are sequentially arranged along the spiral direction on the inner side of the spiral coil, with equal angles between any two adjacent nozzles. The problem with this device is: 1. A pipe is installed around the condenser, which can easily damage the condenser and make it difficult for the condenser to dissipate heat when there is no need to lower the ambient temperature.

[0007] 2. Liquid water sprayed directly onto the condenser fins causes scale buildup on the fins, thus reducing heat dissipation efficiency. Utility Model Content

[0008] In view of this, in order to solve the problem that as outdoor temperatures rise in summer, air-cooled condensers have difficulty releasing heat in extreme high-temperature environments, leading to a decrease in the working efficiency of air conditioning compressors, the utility model provides a water spray device that improves the heat dissipation efficiency of condensers by lowering the ambient temperature.

[0009] To achieve the above-mentioned objectives, this utility model adopts the following technical solution: a water spray device for improving the heat dissipation efficiency of a condenser by reducing the ambient temperature, comprising a water tank and a water distribution pipe disposed on one side of a wall, a float ball and a water pump disposed in the water tank, the water pump being connected to one end of the water distribution pipe via a pipe, nozzles being evenly disposed on the water distribution pipe, a controller and a temperature sensor disposed on the wall, the water pump, the float ball and the temperature sensor being electrically connected to the controller, and the controller controlling the start and stop of the water pump based on the ambient temperature detected by the temperature sensor.

[0010] Furthermore, the water spray device is positioned close to the air conditioner condenser.

[0011] Compared with the prior art, the present invention has the following advantages: 1) The nozzle of this utility model is placed above the air-cooled condenser. It uses water pressure to atomize and diffuse the water, and then uses the gravity of the water to disperse it from top to bottom, so that the tiny water droplets are evenly distributed in the environmental area.

[0012] 2) This utility model utilizes the principle of water evaporating and absorbing heat when it comes into contact with air to reduce the ambient temperature around the air-cooled condenser.

[0013] 3) This utility model's structure, under outdoor high-temperature weather conditions (set to start when ambient temperature > 30℃, stop when ambient temperature < 25℃), controls the system to automatically start during hot seasons. This creates a relatively low-temperature environment for the air-cooled condenser, facilitating heat dissipation and thus improving compressor efficiency. Attached Figure Description

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This embodiment provides a water spray device that improves the heat dissipation efficiency of a condenser by lowering the ambient temperature, such as... Figure 1 As shown, an independent water spraying device is composed of a water distribution pipe 2, nozzles 3, a water tank 4, a controller 5, a water pump 6, a float ball 7, and a temperature sensor 8. The water tank 4 and the water distribution pipe 2 are located on one side of the wall 1. The float ball 7 and the water pump 6 are installed inside the water tank 4. The float ball 7 detects the water level in the water tank 4 to ensure timely water replenishment (this is an existing solution and will not be elaborated here). Tap water or softened water can be used for replenishment. The water pump 6 is connected to one end of the water distribution pipe 2 through a pipe. The water distribution pipe 2 is evenly equipped with nozzles 3. The water sprayed from the nozzles reduces the air temperature. The controller 5 and the temperature sensor 8 are installed on the wall 1. The water pump 6, the float ball 7, and the temperature sensor 8 are electrically connected to the controller 5. The controller 5 controls the start and stop of the water pump 6 based on the ambient temperature detected by the temperature sensor 8.

[0019] The aforementioned controller 5 is an existing model, which only needs to meet the requirements of LCD screen display and remote communication via the 485 protocol, as well as automatic start / stop function based on temperature sensor signals.

[0020] The water tank 4 mentioned above is made of sheet metal and sprayed with anti-rust paint.

[0021] The aforementioned water distribution pipe 2 is an existing component and is a PE pipe.

[0022] The nozzle 3 mentioned above is an existing component and is made of copper.

[0023] This utility model has a float ball installed in the water tank to set a suitable water level line, preventing water from overflowing the tank. When the water level line is too low, water needs to be added.

[0024] This utility model sets the water pump to start when the ambient temperature is >30℃ and to stop when the ambient temperature is <25℃.

[0025] This utility model relates to a water spray device installed at a high position on the side of an air-cooled condenser. It is used to improve the ambient temperature around the existing air-cooled condenser. The water spray device does not spray water directly onto the condenser fins. The air-cooled condenser modified with this utility model can work efficiently and stably in environments exceeding 45°C. Air-cooled condensers dissipate heat through air, and this utility model assists in the heat dissipation of the air-cooled condenser by lowering the temperature of the ambient air around the air-cooled condenser.

[0026] The working principle of this invention is as follows: When the local ambient temperature exceeds 30℃, the temperature sensor 8 sends a signal to the controller 5, which then controls the water pump 6 to start. Under the action of the water pump 6, water is evenly distributed onto the nozzles 3 through the water distribution pipe 2. The nozzles atomize and spray the water into the condenser area. At this time, the water in the condenser area comes into contact with the air for heat and moisture exchange. The water evaporates and absorbs the sensible heat of the high-temperature ambient gas, thus being cooled down and entering the air-cooled condenser to provide a low-temperature environment for the condenser, thereby improving the compressor efficiency. When the water level in the water tank 4 drops to the inlet water level of the float 7 due to evaporation, the float 7 automatically replenishes tap water. When the local ambient temperature is below 25℃, the temperature sensor 8 sends a signal to the controller 5, which then controls the water pump 6 to stop working. This cycle repeats.

[0027] Many specific details have been set forth in the foregoing description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed above.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
