Description

Technical Field

[0001] This utility model relates to the field of air conditioning engineering technology, and in particular to a heat dissipation spray device for computer room air conditioning. Background Technology

[0002] The centralized installation of outdoor air conditioning units in existing computer room designs has significant drawbacks, especially during the high temperatures of summer. Firstly, the large number and dense arrangement of outdoor units, coupled with a substantial increase in air conditioning load due to high temperatures, significantly reduces the cooling efficiency of the air conditioners themselves. Secondly, surrounding walls and other obstacles severely hinder the effective dissipation of heat, leading to the formation of a heat island effect. This heat island effect not only easily triggers high-temperature and high-pressure alarms in the air conditioning system, but in extreme cases, it can even cause system shutdown, posing a serious threat to the stable operation of the equipment.

[0003] In addition, high temperatures significantly reduce the operating efficiency of air conditioners, leading to a substantial increase in energy consumption and a sharp drop in energy efficiency ratio. This not only increases operating costs but also has a negative impact on the environment. Furthermore, this centralized installation method brings difficulties in maintenance and repair. The dense arrangement of equipment complicates access and operation, especially when working at heights, increasing safety risks.

[0004] Long-term heat island effects may also impact the surrounding environment and the structural safety of buildings. High temperatures may accelerate the aging of building materials, affecting their durability, while also increasing the temperature of the surrounding area, negatively impacting the ecological environment and living comfort. Therefore, the existence of these problems urgently requires the search for new solutions to improve the operating efficiency and environmental impact of computer room air conditioning systems. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a computer room air conditioning heat dissipation spray device that improves the stability and efficiency of air conditioning systems and reduces the heat island effect and the risk of air conditioning downtime.

[0006] To achieve the above objectives, this utility model first proposes a heat dissipation spray device for computer room air conditioning, including at least one spray head installed inside the outdoor unit of the air conditioner and a control system for controlling the spray head to spray water according to a set program. The spray end of the spray head faces the fins of the outdoor unit of the air conditioner. The control system includes a controller, a temperature sensor, and a pressure sensor. The temperature sensor is installed outside the condenser of the outdoor unit of the air conditioner to monitor the outdoor temperature. The pressure sensor is installed inside the refrigerant pipe of the air conditioner to monitor the pressure inside the refrigerant pipe of the outdoor unit of the air conditioner. The temperature sensor and the pressure sensor are electrically connected to the controller, and the controller controls the operation of the spray head.

[0007] In this embodiment, the nozzle is connected to the outlet of the water pump via a water pipe, the inlet of the water pump is connected to the water source via a solenoid valve, and the water pump and the solenoid valve are electrically connected to the controller, which controls the opening and closing of the solenoid valve and the water pump.

[0008] In this embodiment, the water pump is a plunger-type or centrifugal pressurized water pump.

[0009] In this embodiment, the nozzle is connected to the water pump via a flexible water pipe.

[0010] In this embodiment, the solenoid valve is connected to the water source via a flexible water pipe.

[0011] In this embodiment, the nozzle is a low-pressure misting nozzle.

[0012] In this embodiment, the fixed end of the nozzle is provided with a magnet or clip to facilitate fixing it to the outdoor unit of the air conditioner.

[0013] With the above structure, this utility model has the following advantages:

[0014] 1. This device monitors the outdoor temperature using a temperature sensor and the refrigerant pressure in the outdoor unit's refrigerant pipes using a pressure sensor. When the temperature or pressure reaches the set upper limit, the controller activates the solenoid valve and water pump to supply water to the nozzles, achieving atomized spray cooling of the outdoor unit. When the temperature or pressure falls below the set lower limit, the controller shuts off the pressurized water pump and solenoid valve, stopping the nozzles from spraying water to the outdoor unit. By cooling the fins through atomized spraying, the heat island effect is reduced, ensuring the stable operation of the air conditioning system and preventing the risk of air conditioner shutdown due to high temperature and high pressure.

[0015] 2. This device is equipped with a controller, which uses a PLC. Different upper and lower limits for temperature and pressure can be set according to different air conditioners, so as to ensure that it can adapt to different air conditioner models and different environments and temperatures.

[0016] 3. The water pipes of this device are flexible, which ensures the versatility of the nozzle placement. The magnets or clips on the nozzle fixing end facilitate the fixing of the nozzle, thereby enabling multi-directional spraying and heat dissipation of the fins.

[0017] 4. The controller of this device can also be set to different water spraying modes when the nozzle is working. By controlling the opening and closing of the solenoid valve through the controller, water can be supplied to the nozzle in a timed or intermittent manner. For example, after humidifying the air conditioner evaporator for 5 seconds, the solenoid valve is closed to stop humidification. After 10 seconds, when the fins have fully evaporated and absorbed heat, the solenoid valve is opened again to humidify the fins. This cycle is repeated to achieve dry and wet alternation, ensuring the cooling effect while saving water.

[0018] In summary, this device utilizes temperature and pressure sensors to monitor the operating status of the outdoor unit of the air conditioner. The intelligent control system automatically starts, using solenoid valves and a water pump to achieve atomized spray cooling. The controller can adjust parameters according to different air conditioner models and environmental conditions, and can also set various spray modes to achieve efficient cooling and conserve water resources. Therefore, this device improves the stability and efficiency of the air conditioning system, achieving energy savings while reducing the risk of heat island effect and air conditioner downtime.
