While these can meet the requirements of the painting process, the surface cooling coils are made of copper or stainless steel tubing, which is costly. Setting up a surface cooling section also requires a lot of additional space. Furthermore, during seasons with large temperature differences, the surface cooling coils may freeze and break due to incomplete or delayed drainage, increasing additional costs. Surface cooling coils usually use copper tubing with fins, which are difficult to repair once frozen, and can also cause equipment shutdowns, affecting production line capacity.

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 an indirect connection through an intermediate medium; and they can refer to the internal connection of 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. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0020] like Figures 1-2 As shown, a coating air conditioner with a spray system includes, along its air duct, a filter section 1, a primary heating coil 2, a spray system 3 for humidifying or dehumidifying the air, and a secondary heating coil 4. The filter section 1 uses an air filter to remove particulate matter from the air, the primary heating coil 2 and the secondary heating coil 4 are used to heat the air, and the spray system 3 dehumidifies or humidifies the air as needed.
[0021] The spraying system includes a temperature control circuit and a spraying circuit. The temperature control circuit sequentially includes an expansion tank 5, a refrigeration / heating unit 6, and a plate heat exchanger 7. The refrigeration / heating unit 6 is connected to the expansion tank 5 and the plate heat exchanger 7 via pipelines. The spraying circuit sequentially includes a water tank 8, a plate heat exchanger 7, and nozzles 9. The water tank 8, plate heat exchanger 7, and nozzles 9 are connected via spraying pipelines. The water tank 8 is positioned below the nozzles 9. The nozzles are used to atomize water into a mist before spraying it out. The coating air conditioner includes a control center that turns the primary heating coil 2, the spraying system 3, and the secondary heating coil 4 on or off according to the ambient temperature.
[0022] In summer, the control center shuts down the primary heating coil 2, turns on the secondary heating coil 4, and activates the cooling / heating unit 6 in cooling mode. The cooling capacity of the pipeline is transferred to the spray circuit via the plate heat exchanger 7. The low-temperature water in the spray pipeline is atomized through nozzles 9 and sprayed out, making full contact with the air to lower the air temperature, thereby releasing moisture and reducing air humidity. The secondary heating coil 4 then raises the air temperature, ensuring that the temperature and humidity of the blown-out air meet the operating requirements.
[0023] In winter, the control center turns on the primary heating coil 2, turns off the secondary heating coil 4, and turns off the cooling / heating unit 6. The air temperature is increased by the primary heating coil 2. At this time, the spray system sprays room temperature atomized water through the nozzles 9 to humidify the air, so that the temperature and humidity of the blown air meet the operating requirements.
[0024] If the temperature difference is large in winter, the control center will turn on the primary heating coil 2, turn off the secondary heating coil 4, and start the heating mode of the cooling / heating unit 6. The heat from the pipeline will be transferred to the spray circuit through the plate heat exchanger 7. The water in the spray pipeline after heat exchange will be atomized and sprayed out through the nozzles 9 to humidify the air.
[0025] In winter, the operating conditions can be achieved by relying on the primary heating coil 2 and the spray system which only has a humidification function. When necessary, the heating mode of the cooling / heating unit 6 can be activated.
[0026] According to one embodiment of the present invention, a booster pump 10 is further provided in the spray pipeline, and the booster pump 10 is located at the outlet of the water tank. The booster pump has a frequency converter, and the booster pump controls the water flow rate through the frequency converter.
[0027] According to one embodiment of the present invention, a water filter 11 is further provided in the spray pipeline, and the water filter 11 is disposed between the booster pump 10 and the plate heat exchanger 7. The water filter is a bag filter to prevent impurities in the water from clogging the nozzles 9.
[0028] According to one embodiment of the present invention, the bottom of the water tank is provided with a discharge port, which is connected to a drain outlet via a discharge pipe 12. A discharge valve is provided between the discharge port and the drain outlet. The water tank is also provided with an overflow pipe 13, which is connected to the drain outlet. A mechanical filter is installed in the water tank to filter impurities in the water tank.
[0029] According to one embodiment of this utility model, the water tank is further provided with a water supply pipe 14, and the water supply pipe 14 is equipped with a solenoid valve. When the solenoid valve is opened, water is supplied to the water tank through the water supply pipe 14; when the solenoid valve is closed, water supply stops.
[0030] According to one embodiment of this utility model, the water tank 8 is further provided with a level gauge 15, which is linked to the solenoid valve of the water replenishment pipe 14. When the level gauge 15 detects that the water in the tank is insufficient, it sends a signal to the control center, and the control center opens the solenoid valve of the water replenishment pipe 14 to replenish the water tank; when the level gauge 15 detects that the water in the tank is sufficient, it sends a signal to the control center, and the control center closes the solenoid valve of the water replenishment pipe 14 to stop replenishing the water tank.
[0031] According to one embodiment of the present invention, the spray system 3 is provided with a front baffle plate 16 at the air inlet, and the front baffle plate 16 is used to prevent the water sprayed out by the spray system 3 from entering the primary heating coil 2.
[0032] According to one embodiment of the present invention, the spray system 3 is provided with a rear baffle plate 17 at the air outlet, and the rear baffle plate 17 is used to prevent the water sprayed out by the spray system 3 from entering the secondary heating coil 4.
[0033] According to one embodiment of this utility model, the coating air conditioner is further equipped with a temperature sensor and a humidity sensor after the secondary heating coil 4. The temperature sensor and the humidity sensor detect the temperature and humidity of the air at the air outlet, and the detection results are displayed or sent to the control center.
[0034] According to one embodiment of this utility model, the temperature sensor and the humidity sensor are electrically connected to the control center of the coating air conditioner. The temperature sensor and the humidity sensor feed back the detection results to the control center, which adjusts the power of the primary heating coil 2, the secondary heating coil 4, and the cooling / heating unit 6, and adjusts the water flow rate of the booster pump based on the detection results, to ensure that the temperature and humidity of the air at the outlet meet the operating requirements.
[0035] In summary, the technical solution provided by this utility model eliminates the need for a surface cooler, reducing the cost of the coating air conditioner and eliminating the risk of the surface cooler freezing. It also saves space in the coating air conditioner. The spray system of this utility model replaces the original surface cooler, spraying low-temperature water for dehumidification in summer and room-temperature or heated water for humidification in winter, achieving two benefits at once and improving the space utilization rate of the coating air conditioner.
[0036] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
