[0005] The utility model discloses a constant temperature and humidity electricity -saving control system, utilizes the cooperation of evaporative cooler and dehumidifier, reaches the energy -conserving requirement simultaneously, and reduces the humidity of indoor too high again.

[0006] A constant temperature and humidity electricity -saving control system, including evaporative cooler and control box, the evaporative cooler with control box electricity is connected, still electricity is connected with temperature sensor, humidity transducer and dehumidifier on the control box, wherein,

[0008] The humidity transducer and dehumidifier are electrically connected to form a humidity control unit, and the humidity control unit can regulate and control indoor humidity.

[0009] In the prior art, evaporative cooler is often used instead of air conditioner to cool factory building to reduce power consumption and save cost. However, the evaporative cooler will increase the humidity of indoor air while reducing the indoor temperature, which poses a great risk to electronic factory buildings such as machine rooms. To ensure that the indoor environment is suitable for the normal operation of servers, the present scheme sets up a temperature control circuit and a humidity control circuit to control the temperature and humidity of the indoor environment, so that the indoor temperature always meets the requirements of the normal operation environment of servers and other electronic or other products.

[0010] The temperature control loop comprises an evaporative air cooler and a temperature sensor. Specifically, the temperature sensor is used to detect the indoor temperature, and the control box controls the working state of the evaporative air cooler according to the detected temperature, so that the indoor temperature is always within the environmental temperature range in which the server can work normally.

[0011] The humidity control loop comprises a humidity sensor and a dehumidifier. The humidity sensor is used to detect the indoor humidity, and the control box is used to control the working state of the dehumidifier according to the detected humidity, so as to ensure that the indoor humidity does not interfere with the normal work of the server and other products.

[0012] Further, the evaporative air cooler comprises a body and a water tank, the water tank is located below the body, and the inner bottom surface of the water tank is a smooth arc surface opening upward.

[0013] The water tank is also provided with a water outlet, and the water outlet is connected to the bottom of the arc surface.

[0014] In order to facilitate the cleaning of the inside of the evaporative air cooler and the outflow of sewage, the bottom of the water tank is provided with a smooth arc structure. Compared with the flat bottom water tank, the water in the water tank can be automatically collected in the arc surface, which is convenient for recycling.

[0015] The water outlet is connected to the bottom of the arc surface, which is convenient for the discharge of cleaned sewage and is not easy to be left in the water tank in a large area to pollute the inside.

[0016] Further, the inside wall of the evaporative air cooler is attached with a wet curtain, the wet curtain is provided with a water spraying pipe near the top, the water spraying pipe is provided with a plurality of spray heads, and the spray heads can face the wet curtain.

[0017] The water in the evaporative air cooler is transported to the water spraying pipe by the water pump and sprayed to the wet curtain through the spray head. The spray head is installed on the water spraying pipe to atomize the water into fine water droplets, which are then sprayed to the wet curtain to reduce the air temperature passing through the wet curtain. The evaporative air cooler often stores water in the inner bottom or sets a separate water tank on its own structure to supply water to the wet curtain continuously. As an implementable solution of the above-mentioned solution, the water spraying pipe is parallel to the wet curtain, the spray heads are uniformly distributed on the water spraying pipe, and the water spraying area of all the spray heads can cover the wet curtain. The water mist is sprayed to the wet curtain more uniformly to ensure that every part of the wet curtain is wet, thereby ensuring the cooling efficiency of the evaporative air cooler.

[0018] Further, the wet curtain is provided with longitudinally distributed support rods on both sides, the end of the water spraying pipe is connected with a connecting head, the connecting head is sleeved on the support rod, and the connecting head can carry the water spraying pipe to make reciprocating motion along the rod body of the support rod.

[0019] The scheme makes the water spraying pipe move along the support rod, and the nozzle can move longitudinally relative to the wet curtain, thereby ensuring that the wet curtain is fully wetted to take away more heat.

[0020] Furthermore, each of the wet curtains is provided with two support rods, one of which is a smooth cylindrical rod, and the other of which is a screw rod, one end of the screw rod being connected with a motor.

[0021] Specifically, the bottom of the machine body is provided with a frame, and the top of the machine body is provided with a wind cylinder. The bottom of the cylindrical rod is fixedly connected with the frame, and the top of the cylindrical rod is fixedly connected with the top of the machine body away from the wind cylinder. The bottom of the screw rod is rotatably connected with the frame, and the top of the screw rod is rotatably connected with the top of the machine body away from the wind cylinder. The bottom of the frame is provided with a connecting frame facing the water tank, and a water pump and a water level detector are arranged on the connecting frame. The water pump is in contact with the bottom of the water tank but does not block the drain. The water pump and the water spraying pipe are connected by a hose, which facilitates the movement of the position of the water spraying pipe, makes the hose close to the support rod, and does not affect other working structures inside the evaporative cooler.

[0022] The screw rod is adopted to drive the water spraying pipe to move linearly in the longitudinal direction, which is simple in structure, reliable, and easy to obtain.

[0023] Furthermore, the water spraying pipe is further fixedly connected with a cleaning device, the position of the cleaning device on the water spraying pipe is away from the position of the nozzle, and the cleaning device can contact and clean the wet curtain.

[0024] If the wet curtain is not cleaned in time, the holes of the wet curtain may be blocked, which affects the air quality and limits the wind speed, thereby reducing the cooling effect of the evaporative cooler and increasing the energy consumption. However, in actual use, the cleaning of the wet curtain is relatively troublesome, and the cleaning frequency may not be high. The cleaning device is arranged inside the evaporative cooler in the scheme, which is used to simply clean the wet curtain, thereby ensuring the cleanliness of the wet curtain to a certain extent, reducing the energy consumption, and reducing the cleaning frequency of the deep layer of the wet curtain.

[0025] Furthermore, the plurality of nozzles are located on one side of the water spraying pipe, the cleaning device is located on the other side of the water spraying pipe, and the water spraying pipe is rotatably connected with the connecting head.

[0026] The nozzle and the cleaning device are arranged on the water spraying pipe, which saves the internal space. The water spraying pipe can carry the cleaning device to move longitudinally and reciprocally, thereby cleaning the wet curtain comprehensively, ensuring the cleanliness of the air outlet of the evaporative cooler, and further reducing the energy consumption of the evaporative cooler.

[0027] Furthermore, the side of the connecting head facing the water spraying pipe is provided with an inner recessed groove, a rotating head is rotatably connected in the groove, the rotating head is gear-shaped, and the rotating head is further provided with a driving gear capable of engaging with the rotating head.

[0028] The end of the water spraying pipe is provided with a port plug, which can be clamped with the rotating head.

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the utility model is further described in detail below by combining with examples and drawings, the schematic implementation mode of the utility model and its description are only used to explain the utility model, and do not serve as the limitation of the utility model.

[0044] Embodiment:

[0045] As Figures 1-7 shown, a constant-temperature and constant-humidity power-saving control system includes an evaporative air cooler 2 and a control box 1, the evaporative air cooler 2 is electrically connected with the control box 1, and the control box 1 is further electrically connected with a temperature sensor 4, a humidity sensor 5 and a dehumidifier 6, wherein,

[0046] The evaporative air cooler 2 and the temperature sensor 4 are electrically connected to form a temperature control unit, and the temperature control unit can regulate and control the indoor temperature.

[0047] The humidity sensor 5 and the dehumidifier 6 are electrically connected to form a humidity control unit, and the humidity control unit can regulate and control the indoor humidity.

[0048] In the prior art, the evaporative air cooler 2 is often used to replace the air conditioner to reduce the power consumption and save the cost. However, the evaporative air cooler 2 can increase the indoor air humidity while reducing the indoor temperature, which can cause great hidden dangers in the electronic factory room. In order to ensure that the indoor environment is the normal working environment of the server, the temperature control loop and the humidity control loop are arranged in the present scheme to control the indoor temperature and humidity, so that the indoor temperature always meets the normal working environment requirements of the server and other electronic or other products.

[0049] Specifically, based on the existing axial flow air cooler of CY18-B type, the temperature control loop of the present scheme includes the evaporative air cooler 2 and the temperature sensor 4. Specifically, the temperature sensor 4 is used to detect the indoor temperature, and the control box 1 controls the working state of the evaporative air cooler 2 according to the detected temperature, so that the indoor temperature is always within the environmental temperature range of the normal working of the server.

[0050] The humidity control loop includes a humidity sensor 5 and a dehumidifier 6. The humidity sensor 5 is used to detect the indoor humidity, and the control box 1 is used to control the working status of the dehumidifier 6 based on the detected humidity, thereby ensuring that the indoor humidity does not interfere with the normal operation of products such as servers.

[0051] Specifically, such as Figure 1 As shown, the area within the dashed box represents the indoor space. The evaporative air cooler 2 is installed outdoors, and cool air enters the room through the air duct 3 via the top of the evaporative air cooler 2. A control box 1 is installed indoors, containing a temperature sensor and a humidity sensor. The software installation box is electrically connected to the evaporative air cooler 2 and the dehumidifier 6. The temperature sensor is connected in series with the evaporative air cooler 2 in the temperature control loop, and the humidity sensor is connected in series with the dehumidifier 6 in the humidity control loop. This allows for real-time monitoring and adjustment of the indoor temperature and humidity to ensure a consistently suitable indoor environment and normal server operation. Specifically, the condensate produced by the dehumidifier 6 is automatically collected in its own water tank and then drained outdoors via a connected water pipe.

[0052] In the specific implementation of the above scheme, dual-purpose temperature and humidity sensors such as H-THNSJ0A, H-THRJ45, H-THRJ45P, HB-TH610, or HB-TH620 can be used.

[0053] As one possible implementation of the above solution, the dehumidifier 6 uses an air conditioner with dehumidification function. While using the air conditioner to dehumidify, it can also assist the evaporative air cooler 2 in cooling the room. Because the cool air from the evaporative air cooler 2 will lower the indoor temperature, the energy consumption of this solution will still be lower than that of using only the air conditioner to control the indoor temperature and humidity.

[0054] Furthermore, the evaporative air cooler 2 includes a body 21 and a water tank 22, the water tank 22 being located below the body 21, and the inner bottom surface of the water tank 22 being a smooth arc surface with an opening facing upwards;

[0055] The water tank 22 is also provided with a water outlet 28, which is connected to the bottom of the arc surface.

[0056] To facilitate cleaning of the interior of the evaporative air cooler 2 and to facilitate the outflow of wastewater, this design sets the bottom of the water tank 22 as a smooth arc-shaped structure. Compared with a flat-bottomed water tank 22, this design can automatically collect the water in the water tank 22 into the arc surface, which facilitates water recycling.

[0057] The outlet 28 is connected to the bottom of the curved surface, which facilitates the discharge of wastewater after cleaning and prevents it from leaving a large area of ​​residue in the water tank 22 and causing internal pollution.

[0058] In the specific implementation of the above scheme, the water tank 22 also has an inlet 27, which is positioned higher than the outlet 28.

[0059] As one possible implementation of the above solution, such as Figure 2 The evaporative air cooler 2 has a frame support structure between its body 21 and water tank 22. Two connecting rods are connected to the bottom of the frame support structure, and a flat plate is fixed to the bottom of each rod. The flat plate has several water filter holes, and the water pump is placed on the flat plate, separate from the water outlet hole at the bottom of the curved surface. During operation, the water tank always maintains a certain water level to ensure sufficient water is sprayed onto the water curtain through the nozzles, ensuring the evaporative air cooler 2 can operate normally. The curved bottom of the water tank facilitates water storage and drainage. Furthermore, compared to a flat-bottomed water tank, this design provides a higher water level for the same water volume, facilitating pump startup and reducing the water demand for pump startup, thus compensating for the pump's lower-than-bottom placement.

[0060] In practical implementation, the above-mentioned feasible solution can be equipped with a water level sensor on the flat plate to detect the water level in the water tank, prevent the water pump from running dry, and ensure that the evaporative air cooler 2 has sufficient water to maintain normal operation. Furthermore, the inner wall of the evaporative air cooler 2 is fitted with an evaporative air cooler, and a water spray pipe 25 is provided near the top of the evaporative air cooler. The water spray pipe 25 is equipped with several nozzles 29, which can face the evaporative air cooler.

[0061] Water inside the evaporative air cooler 2 is transported by a water pump to the spray pipe 25 and then sprayed onto the evaporative cooling pad through the nozzles 29. The nozzles 29, installed on the spray pipe 25, atomize the water into fine droplets, which are then sprayed onto the evaporative cooling pad, thereby reducing the temperature of the air passing through it. The evaporative air cooler 2 typically stores water at its bottom or has a separate water tank in its structure to continuously supply water to the evaporative cooling pad. As one possible implementation, the spray pipe 25 is parallel to the evaporative cooling pad, and the nozzles 29 are evenly distributed along the spray pipe 25, ensuring that the spray area of ​​all nozzles 29 covers the evaporative cooling pad. This more even spraying of water mist onto the evaporative cooling pad ensures that every part of the pad is moistened, thus guaranteeing the cooling efficiency of the evaporative air cooler 2.

[0062] Furthermore, the wet curtain is provided with longitudinally distributed support rods 26 on both sides, and the end of the water spray pipe 25 is connected to a connector 24. The connector 24 is sleeved on the support rod 26, and the connector 24 can carry the water spray pipe 25 to reciprocate along the body of the support rod 26.

[0063] This design allows the water spray pipe 25 to move along the support rod 26, so that the nozzle 29 can move longitudinally relative to the wet curtain, thereby ensuring that the wet curtain is fully wetted to remove more heat.

[0064] Further, each of the wet curtains is provided with two support rods 26, one of which is a smooth cylindrical rod, and the other is a screw rod, one end of which is connected with a motor.

[0065] In the implementation of the above scheme, the bottom of the body 21 is provided with a frame, and the top of the body 21 is provided with a wind cylinder. The bottom of the cylindrical rod is fixedly connected with the frame, and the top of the cylindrical rod is fixedly connected with the top of the body 21, avoiding the wind cylinder. The bottom of the screw rod is rotatably connected with the frame, and the top of the screw rod is rotatably connected with the top of the body 21, avoiding the wind cylinder, and the screw rod is driven by the motor.

[0066] The water pump is connected with the water spraying pipe 25 by a hose, which facilitates the movement of the water spraying pipe 25 and makes the position of the hose close to the support rod 26, without affecting other working structures inside the evaporative cooler.

[0067] The motor drives the rotation of the screw rod, so that the water spraying pipe 25 moves linearly in the longitudinal direction due to the restriction of the screw rod and the cylindrical rod, which is simple and reliable, and easy to obtain.

[0068] Further, the water spraying pipe 25 is also fixedly connected with a cleaning device 23, the position of the cleaning device 23 on the water spraying pipe 25 avoids the position of the spray head 29, and the cleaning device 23 can contact and clean the wet curtain.

[0069] If the wet curtain is not cleaned in time, it may block the holes of the wet curtain, affect the air quality and limit the wind speed, thereby reducing the cooling effect of the evaporative cooler 2 and increasing the energy consumption. However, in actual use, the cleaning of the wet curtain is more troublesome, and the cleaning frequency may not be high. The cleaning device 23 is arranged inside the evaporative cooler 2 to simply clean the wet curtain, thereby ensuring the cleanliness of the wet curtain to a certain extent, reducing the energy consumption and reducing the cleaning frequency of the deep layer of the wet curtain.

[0070] The cleaning device 23 and the spray head 29 are both fixedly arranged on the water spraying pipe 25, and when the water spraying pipe 25 rotates, the cleaning device 23 and the spray head 29 will rotate together, and the arrangement positions of the two on the water spraying pipe 25 are different, and they will not interfere with each other in the process of rotation.

[0071] In the implementation of the above scheme, the cleaning device 23 can use a soft brush or a cloth strip that is not easy to deform.

[0072] It should be noted that although the low water pressure from the inside to the outside can achieve a certain degree of cleaning effect, the surface of the wet curtain used for a long time may be attached with scale, sticky substances or blocking materials between the fibers of the wet curtain. Directly washing the wet curtain with the spray head 29 at low water pressure cannot achieve the cleaning purpose, and a soft brush still needs to be used for cleaning. The present scheme can achieve deep cleaning of the wet curtain without manually disassembling the evaporative cooler 2, thereby improving the efficiency.

[0073] Further, several of the spray heads 29 are located on one side of the water spraying pipe 25, and the cleaning device 23 is located on the other side of the water spraying pipe 25, and the water spraying pipe 25 is rotationally connected with the connecting head 24.

[0074] The spray head 29 and the cleaning device 23 are both arranged on the water spraying pipe 25, thereby saving internal space.

[0075] The water spraying pipe 25 can carry the cleaning device 23 to reciprocate longitudinally, thereby cleaning the wet curtain comprehensively, ensuring the air cleanliness of the evaporative air cooler 2 and further reducing the energy consumption of the evaporative air cooler 2.

[0076] Further, the side of the connecting head 24 facing the water spraying pipe 25 is provided with a concave groove, the groove rotationally connects with a rotating head 211, the rotating head 211 is a gear, and the rotating head 211 is further provided with a driving gear 212 capable of engaging with the rotating head 211.

[0077] The end of the water spraying pipe 25 is provided with a port plug 210, and the port plug 210 can be clamped with the rotating head 211.

[0078] As Figures 6-7 , by rotating the driving gear 212, the rotating head 211 is driven to rotate, and since the rotating head 211 is rotationally connected with the groove of the connecting head 24, the connecting head 24 does not rotate; at the same time, since the port plug 210 and the rotating head 211 are clamped with each other, when the rotating head 211 rotates, the water spraying pipe 25 will be driven to rotate, thereby making the cleaning device 23 and the spray head 29 arranged on the water spraying pipe 25 rotate together, realizing the direction switching of the spray head 29 and the cleaning device 23, changing the specific structure acting on the wet curtain, and realizing the switching of the working and cleaning states of the evaporative air cooler 2.

[0079] Specifically, in working, the spray head 29 sprays water to the wet curtain, and in cleaning, the cleaning device 23 faces the wet curtain and moves longitudinally to clean the surface of the wet curtain from top to bottom, and when the cleaning is completed and the cleaning device 23 is close to the bottom of the wet curtain, the rotating head 211 is driven to rotate by using a motor, and the spray head 29 is adjusted to face the wet curtain. In the specific implementation of the above scheme, in order to make the water spraying pipe 25 rotate 180 degrees at one time, the rotating head 211 is made to rotate 180 degrees when the driving gear 212 rotates an integer number of turns, and the direction of the spray head 29 on the water spraying pipe 25 is switched by controlling the number of turns of the driving gear 212; or the rotating head 211 is made to be a half gear, and the direction of the spray head 29 is changed by changing the rotating direction of the driving gear 212.

[0080] The above specific embodiments explain the purpose, technical scheme and beneficial effects of the present application in further detail, and it should be understood that the above description is only a specific embodiment of the present application and is not used to limit the protection scope of the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
