Description

Technical Field

[0001] This invention belongs to the field of air handling equipment technology, and particularly relates to a data center fresh air temperature and humidity control system. Background Technology

[0002] Fresh air handling units draw in fresh outdoor air, process it through dust removal, dehumidification (or humidification), and cooling (or heating), and then deliver it indoors via a fan. As it enters the indoor space, it replaces the existing indoor air, keeping the indoor air fresh at all times and avoiding the health hazards that may result from staying in air-conditioned rooms for extended periods.

[0003] Existing dehumidification devices use salt solution dehumidification devices. By contacting air with salt water, which has a strong moisture absorption capacity, the water vapor in the air is absorbed by the salt water, thus achieving a dehumidification effect. However, the concentration of the salt water decreases after use, affecting the subsequent dehumidification effect. Regeneration is usually required. This is generally achieved by heating and evaporating the water in the salt water to increase the concentration. However, the temperature of the salt solution also increases, which is not conducive to dehumidifying the air. Therefore, a separate cooling device is also required to cool the solution, resulting in high energy consumption and high cost. Summary of the Invention

A first water pump has a first suction pipe installed at one end and a first water outlet pipe installed at the other end. A dehumidification box is installed on the inner wall of the air supply room.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] See attached document Figure 1-6A data center fresh air temperature and humidity control system includes an air supply room 1 and a server room. The server room is located at one end of the air supply room 1. A motor 101 is fixedly installed on the inner wall of the air supply room 1. A fan blade 102 is installed at the output end of the motor 101 to draw outdoor air into the air supply room 1. A water pump 103 is fixedly installed on the inner wall of the air supply room 1. A water suction pipe 104 is installed at one end of the water pump 103, and a water discharge pipe 105 is installed at the other end of the water pump 103. A dehumidification box 106 is installed on the inner wall of the air supply room 1. The brine level is located at two-thirds of the depth of the dehumidification chamber 106. A first-stage water intake pipe 104 is installed on the outer wall of the dehumidification chamber 106, at the bottom of the outer wall. A second-stage water outlet pipe 109 is installed on the outer wall of the dehumidification chamber 106. A second-stage water pump 107 is installed on the inner wall of the air supply room 1. A second-stage water intake pipe 108 is installed at one end of the second-stage water pump 107, and a second-stage water outlet pipe 109 is installed at the other end. The second-stage water outlet pipe 109 is located at the top of the outer wall of the dehumidification chamber 106, and its outer wall is equipped with… A return pipe 110 is provided, with a solenoid valve 111 installed at both ends to control the opening and closing of the return pipe 110 channel. A solenoid valve 112 is installed on the outer wall of the second outlet pipe 109. A suction pipe 104 is installed around the outer wall of the first motor 101. The return pipe 110 is installed around the outer wall of the cooler 206. An exhaust pipe 2 is installed on the inner wall of the air supply room 1. An air inlet pipe 201 is installed on the inner wall of the air supply room 1. One end of the air inlet pipe 201 is branched into a hot air channel 202 and a cold air channel 205. The inner wall of the air supply room 1 is opened... There is a hot air duct 202, and a heater 203 is installed on the inner wall of the hot air duct 202. An air outlet duct 204 is opened on the inner wall of the air supply room 1. One end of the air outlet duct 204 is connected to the hot air duct 202 and the cold air duct 205. A cooler 206 is installed on the inner wall of the cold air duct 205. A brine tank 207 is also provided inside the air supply room 1. A vent is opened on one side of the air supply room 1 at the brine tank 207. A heating plate 208 is installed on the inner wall of the brine tank 207 for evaporating the water in the brine.

[0027] Motor 101 starts, driving fan blades 102 to rotate, causing outdoor air to enter the dehumidification chamber 106 containing brine through exhaust pipe 2 for dehumidification. The dehumidified air then enters either hot air duct 202 or cold air duct 205 depending on the temperature, and is then discharged from exhaust duct 204. When it is hot outdoors, cooler 206 operates, opening two solenoid valves 111 and closing solenoid valve 112. Water pump 107 draws brine from brine tank 207, which flows through outlet pipe 109 into return pipe 110 and then back into dehumidification chamber 106, where cooler 206 cools the brine. When it is cold outdoors, heater 203 operates, closing two solenoid valves 111 and opening solenoid valve 112. The solenoid valve 112 and the second water pump 107 draw brine from the brine tank 207 and directly into the dehumidification box 106 through the second water outlet pipe 109. Since a long portion of the second water outlet pipe 109 extends to the outside of the air supply room 1, it is in an outdoor environment, where the brine is cooled by the low outdoor temperature. The first water pump 103 starts and draws the brine from the dehumidification box 106 through the first water suction pipe 104 and then discharges it into the brine tank 207 through the first water outlet pipe 105. Since the first motor 101 generates a lot of heat when it starts, it can heat up the brine in the first water suction pipe 104, allowing the brine in the brine tank 207 to heat up quickly. It can also cool down the first motor 101, avoiding the high cost of brine regeneration treatment.

[0028] The air supply room 1 has a humidification channel 3 located at the top of the brine tank 207. A fan 301 is fixedly installed on the inner wall of the humidification channel 3, and a condenser pipe 302 is installed on the outer wall of the humidification channel 3. A cooling cylinder 303 is installed on the inner wall of the air supply room 1. A support column 304 is fixedly installed on the bottom wall of the cooling cylinder 303. The condenser pipe 302 is wrapped around the support column 304. A water collection tank 305 is installed on the inner wall of the air supply room 1. An atomizer 307 is installed on the inner wall of the air supply room 1. A filter screen is installed at one end of the atomizer 307, which can filter the water in the water collection tank 305 during atomization. A water inlet pipe 306 is installed at one end of the atomizer 307.

[0029] Water vapor evaporated in the salt water tank 207 enters the condenser tube 302 through the humidification channel 3 via the fan 301 and condenses into water, which then flows into the water collection tank 305. When it is necessary to increase humidity, the atomizer 307 is activated, and the water in the water collection tank 305 is atomized and discharged through the water inlet pipe 306, thereby increasing the indoor humidity.

[0030] A second housing 4 is installed on the top of the dehumidification box 106. A second motor 401 is installed on the inner wall of the second housing 4. A threaded rod 402 is installed on the output end of the second motor 401. A limit rod 403 is fixedly installed on the inner top wall of the dehumidification box 106. A limit tube 404 is slidably installed on the outer wall of the air inlet pipe 201. An electric telescopic rod 5 is fixedly installed on the inner wall of the air supply room 1. A baffle 501 is installed at one end of the electric telescopic rod 5. When the heater 203 is working, the electric telescopic rod 5 is activated to block the cold air passage 205 through the baffle 501. When the cooler 206 is working, the electric telescopic rod 5 is activated to block the hot air passage 202 through the baffle 501. An air inlet passage 6 is provided between the top of the air supply room 1 and the exhaust pipe 2. An air supply passage 601 for the machine room is provided at the connection position of the air supply room 1 and at the position of the air outlet passage 204.

[0031] The start of motor 401 causes the threaded rod 402 at the output end to rotate within the limiting tube 404. Under the action of the limiting rod 403, the limiting tube 404 can slide on the exhaust pipe 2. The air drawn out from the exhaust pipe 2 is discharged through the limiting tube 404. When it is necessary to strengthen the dehumidification of the air, the limiting tube 404 moves downward. The position of the limiting tube 404 is close to the bottom of the dehumidification box 106, and the contact time between the air and the salt water will be longer, thereby adjusting the intensity of air dehumidification.

[0032] Working principle: Those skilled in the art start motor 101, which drives fan blade 102 to rotate, causing outdoor air to enter the dehumidification chamber 106 containing brine through exhaust pipe 2 for dehumidification. The dehumidified air then enters either hot air duct 202 or cold air duct 205 depending on the temperature, and is then discharged from exhaust duct 204. It is then sent into the machine room through air supply duct 601. When it is hot outside, cooler 206 operates, opening two solenoid valves 111 and closing solenoid valve 112. Water pump 107 then draws out brine from the brine tank 2. The brine in pool 207 enters the return pipe 110 through outlet pipe 109 and then enters the dehumidification chamber 106 through outlet pipe 109. The brine is cooled by cooler 206. When the outdoor temperature is low, heater 203 operates, closing both solenoid valves 111 and opening solenoid valve 112. Pump 107 draws brine from pool 207 directly into the dehumidification chamber 106 through outlet pipe 109. In the outdoor environment, the low outdoor temperature cools the brine. Pump 103 starts, drawing brine from the dehumidification chamber 106 through a... The brine is drawn out through the No. 1 pumping pipe 104 and discharged into the brine tank 207 through the No. 1 outlet pipe 105. Since the No. 1 motor 101 generates significant heat when starting, it heats the brine in the No. 1 pumping pipe 104, allowing the brine in the brine tank 207 to heat up rapidly. It also cools the No. 1 motor 101, avoiding high costs associated with brine regeneration. Water vapor evaporated in the brine tank 207 is condensed into water through the humidification channel 3 via the fan 301, then flows into the water collection tank 305. When increased humidity is needed, the atomizer 3 is activated. 07. Water in the water tank 305 is atomized and discharged through the water inlet pipe 306, thereby increasing the indoor humidity. The second motor 401 starts, causing the threaded rod 402 at the output end to rotate in the limiting tube 404. Under the action of the limiting rod 403, the limiting tube 404 can slide on the exhaust pipe 2. The air drawn from the exhaust pipe 2 is discharged through the limiting tube 404. When it is necessary to strengthen the dehumidification of the air, the limiting tube 404 moves downward. The position of the limiting tube 404 is close to the bottom of the dehumidification box 106, and the contact time between the air and the salt water will be longer, thereby adjusting the intensity of air dehumidification.
