Description

Technical Field

[0001] This invention belongs to the technical field of air conditioning equipment, and particularly relates to a high-precision temperature and humidity control system for workshops and laboratories. Background Technology

[0002] In industries such as biology, pharmaceuticals, electronics and semiconductors, and food, fluctuations in temperature and humidity in workshops and laboratories during experiments and production can lead to distorted results, equipment damage, experimental failures, and low yields. This is especially true for products requiring high-precision review and testing. Therefore, temperature and humidity control systems are extremely important for workshops and laboratories in these industries. However, in conventional workshops and laboratories, the walls generally have a certain degree of thermal conductivity, making the air temperature inside the workshop and laboratory highly susceptible to the influence of outdoor weather and temperature at all times. As a result, it is difficult for temperature and humidity control systems (i.e., air conditioning systems) to uniformly and accurately regulate the temperature in the workshop and laboratory, and uneven air temperature can easily occur in different parts of the workshop and laboratory. Summary of the Invention

[0003] The purpose of this invention is to provide a high-precision temperature and humidity control system for workshops and laboratories to solve the technical problems described in the background.

[0004] A high-precision temperature and humidity control system for workshops and laboratories includes: A circulating chiller unit is a space that restricts the range of air movement. The circulating chiller unit is equipped with a circulating heat exchanger and a circulating temperature sensor. The circulating heat exchanger is connected to the cooling capacity of the circulating cold source unit, and the circulating temperature sensor is used to monitor the air temperature inside the circulating chiller unit. The terminal room is surrounded by a return air wall. The return air wall has a return air duct that connects to the beginning of the circulating unit. The bottom of the return air wall has a return air inlet that connects to the bottom of the terminal room. The end of the circulating unit is connected to the terminal room. After the air temperature and humidity inside the circulating heat exchanger are adjusted to the set temperature, the air is delivered from the end of the circulating heat exchanger to the terminal room to regulate the temperature and humidity of the terminal room. The air in the terminal room enters the return air wall through the return air vent and flows back to the circulating heat exchanger for temperature and humidity regulation. The return air wall and the air flowing inside it are used to insulate the terminal room from the outdoor space.

[0005] Based on the above technical solutions, the present invention achieves the following beneficial effects: 1. When the outdoor weather, temperature, and humidity change drastically, and there is a temperature difference between the outdoor environment and the terminal room, the return air wall isolates the terminal room from the outdoor space, thereby preventing the outdoor weather from affecting the temperature in the terminal room, improving the accuracy and stability of the circulating unit in regulating the air temperature in the terminal room, and reducing the air temperature difference in various parts of the terminal room. 2. Since the air in the terminal room flows back to the recirculation unit through the return air wall, the temperature of the return air wall is close to the temperature in the terminal room, thereby further reducing the impact of the outdoor air temperature on the terminal room.

[0006] To further optimize the above technical solutions, they can be combined with one or more of the following implementation methods without conflict.

[0007] In some implementations, the terminal room is equipped with a microporous floor, and a basement is provided below the microporous floor. By utilizing the density difference between air at different temperatures, the low-temperature air in the terminal room leaks into the basement and does not accumulate on the ground. The return air vent is located in the basement. According to the above technical solution, low-temperature air can be prevented from accumulating on the ground, thereby reducing the air temperature difference at different heights in the terminal room.

[0008] In some implementations, several exhaust channels are arranged at the bottom of the underground layer, and underground fans are installed at intervals in each exhaust channel. After the low-temperature air in the underground layer sinks into the exhaust channel, the underground fans send the air in the exhaust channel to the return air vent. According to the above technical solution, the air falling into the underground layer can be more efficiently transported to the return air vent and enter the return air wall, thereby avoiding the accumulation of low-temperature air in the underground layer.

[0009] In some implementations, room temperature and humidity sensors are installed at different heights in the terminal room. The end of the circulation unit is connected to the top of the terminal room. An air cooling capacity control valve is installed at the connection between the circulation unit and the terminal room to control the amount of air input into the terminal room by the circulation unit according to the density difference between air at different temperatures, thereby regulating the temperature at different heights in the terminal room. A booster fan that delivers air upwards is installed at intervals inside the return air wall. Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. When cooling the terminal room, cold air enters through the top of the terminal room and fills the entire terminal room by falling, thereby reducing the density difference between air at different temperatures and causing temperature differences in spaces at different heights. 2. The auxiliary fan can efficiently return the cold air falling into the interlayer to the circulation unit through the return air wall.

[0010] In addition, conventional temperature and humidity control systems (i.e., air conditioning) have the following problems when used in these laboratories and workshops: 1. Since traditional temperature and humidity control systems consist of an outdoor unit and an indoor unit, and the indoor unit is usually located in a certain position in the room, or the temperature and humidity control system is located in a certain position, there will be temperature deviations between different spaces in the room; 2. Since the air density is different at different temperatures, there will be temperature deviations at different heights in the room.

[0011] Therefore, in some embodiments, a mezzanine is provided at the top of the terminal room, and the end of the circulation unit is connected to the top of the mezzanine so that the circulation unit delivers air and fills the mezzanine. The bottom wall of the mezzanine is a microporous aluminum plate connected to the terminal room. According to the above technical solution, by utilizing the density difference between air at different temperatures, the cold air in the interlayer sinks and fills the microporous aluminum plate. Then, the cold air passes through the microporous aluminum plate and falls into the terminal room, thereby dispersing the cold air and uniformly covering all areas of the terminal room, so as to further reduce the deviation between the various spaces in the terminal room.

[0012] In some implementations, the microporous aluminum plate array is equipped with several air compressors. The air compressors are used to press the air in the interlayer down to the bottom of the terminal room and fill the terminal room. Temperature and humidity sensors are installed below the air compressors. By independently controlling the air speed of each air compressor, the temperature of each area in the terminal room can be regulated, thereby achieving more precise temperature regulation of each part of the terminal room and further reducing the deviation between different spaces in the terminal room.

[0013] In some implementations, when an object is placed in the terminal room, a guide plate is installed on the top surface of the object. The guide plate has curved edges at its perimeter. An inwardly inclined guide wing is installed next to the curved edge on the guide plate. The guide wing has a curved guide surface, the middle of which is at the same height as the guide plate. When air in the interlayer impacts the guide plate and disperses outward, the curved guide surface directs the outwardly dispersed air downward along the side wall of the object, reducing interference with the surrounding airflow. The top wall of the guide wing has an outwardly curved outer guide surface, so that when air in the interlayer impacts the top of the guide wing, the airflow passes over the outside of the guide wing, avoiding interference with the surrounding airflow. A deflector column is installed below the guide wing to prevent airflow from forming vortices that would interfere with the surrounding airflow. The airflow disturbed by the deflector column is then carried downward by the surrounding airflow. Therefore, the interference of the airflow impacting the object on the surrounding airflow is reduced.

[0014] In addition to the above, conventional temperature and humidity control systems (i.e., air conditioners) also present the following problems when used in these laboratories and workshops: 1. Since conventional temperature and humidity control systems mainly use Freon and other substances to transfer heat between indoors and outdoors, when the outdoor weather, temperature, and humidity change drastically, the heat transfer effect, efficiency, and stability will be affected, resulting in unstable and inaccurate efficiency in regulating indoor temperature, thus affecting indoor air temperature and humidity; 2. In order to save energy and ensure the heat transfer effect, conventional temperature and humidity control systems generally control the compressor to work at full load intermittently, while operating at a minimum load during other times. This results in temperature deviations in the room at different times. Furthermore, when the demand for air conditioning is less than the minimum operating load, the main unit loses its regulating ability.

[0015] Therefore, in some embodiments, this high-precision temperature and humidity control system for workshops and laboratories further includes a fresh air unit, which is another space that restricts the range of air movement. A fresh air duct is provided at the beginning of the fresh air unit, and the end of the fresh air unit is connected to the beginning of a circulation unit. The fresh air unit contains: The fresh air temperature sensor and the fresh air heat exchanger are used to monitor the air temperature inside the fresh air handling unit. The fresh air heat exchanger is connected to the cooling capacity of the fresh air cooling source unit. After the outdoor air enters the fresh air handling unit through the fresh air duct, it passes through the fresh air heat exchanger and the fresh air temperature sensor to perform initial temperature regulation. After that, the air in the fresh air handling unit enters the circulation unit. At this time, the circulation heat exchanger and the circulation temperature sensor perform precise temperature regulation of the air. Fresh air filters are used to purify the air entering from the fresh air duct. Fresh air humidity sensor is used to monitor the humidity of the air entering from the fresh air duct. The fresh air heat exchanger removes the heat from the air and condenses the moisture in the air to adjust the air humidity. The fresh air heating module is used to heat the air when the air temperature is lower than the set value in order to reduce air humidity, or when the air temperature entering from the fresh air duct is lower than the set value. A fresh air unit is used to push the air in the fresh air handling unit into the circulation unit, thereby improving the efficiency of air entering the circulation unit from the fresh air handling unit.

[0016] Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. Before entering the terminal room, outdoor air enters the fresh air unit through the fresh air duct. The fresh air temperature sensor obtains the air temperature information inside the fresh air unit, and the fresh air cooling source unit supplies cooling capacity to the fresh air heat exchanger to initially regulate the air to the set range. After that, the air is sent to the circulation unit. The circulation temperature sensor obtains the air temperature information inside the circulation unit, and the circulation cooling source unit supplies cooling capacity to the circulation heat exchanger to finely adjust the air temperature a second time. Finally, the air is sent to the terminal room. Therefore, the air temperature entering the terminal room can be regulated with high precision. 2. Since the air in the terminal room can be returned to the circulating unit through the return air duct, the temperature information of the returned air is obtained through the circulating temperature sensor, and the circulating cold source host is used to deliver cooling capacity to the circulating heat exchanger to achieve real-time temperature control of the air in the terminal room. 3. When drastic changes in outdoor weather, temperature, and humidity affect the temperature regulation efficiency and accuracy of the fresh air handling unit, the air inside the fresh air handling unit can be re-temperature regulated by the circulation unit before entering the terminal room. In addition, when drastic changes in outdoor weather, temperature, and humidity affect the temperature regulation efficiency and accuracy of the circulation unit, the fresh air handling unit can supplement and mix in air of another temperature value to assist the circulation unit in adjusting the temperature of the air inside to the set value, thereby reducing the impact of external weather changes on the air in the terminal room.

[0017] In some implementations, the circulating unit is also equipped with: Recirculating air filters are used to purify the air entering the terminal room; The circulating humidity sensor is used to monitor the humidity of the air entering the circulating unit. It removes heat from the air through the circulating heat exchanger, causing the moisture in the air to condense, so as to accurately adjust the humidity of the air. The circulating heating module is used to heat the air when the air temperature is lower than the set value in order to reduce air humidity, or when the air temperature entering the circulating unit is lower than the set value. A circulating fan is used to push the air in the circulating unit into the terminal room. A humidifier is used to humidify the air when the humidity inside the circulating unit is lower than the set value.

[0018] Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. Before outdoor air enters the terminal room, the humidity information of the air inside the fresh air unit is obtained through the fresh air humidity sensor. The fresh air heat exchanger removes the heat of the air and condenses the moisture in the air to initially adjust the humidity to the set range. After that, the air is delivered to the circulation unit, where the humidity information of the air inside the circulation unit is obtained through the circulation humidity sensor. The circulation heat exchanger removes the heat of the air and condenses the moisture in the air to finely adjust the humidity setting a second time. Finally, the air is delivered to the terminal room. Therefore, the temperature of the air entering the terminal room can be regulated with high precision. 2. Since the air in the terminal room can be returned to the circulating unit through the return air duct, the temperature information of the returned air is obtained through the circulating humidity sensor, and the heat of the air is removed by the circulating heat exchanger to condense the moisture in the air. When the humidity of the air in the terminal room is too low, the air can be humidified by the humidifier to achieve real-time humidity control of the air in the terminal room. 3. When drastic changes in outdoor weather, temperature, and humidity affect the dehumidification efficiency and humidity control accuracy of the fresh air handling unit, the air inside the fresh air handling unit can be dehumidified a second time by the circulation unit before entering the terminal room. In addition, when drastic changes in outdoor weather, temperature, and humidity affect the humidity control efficiency and temperature control accuracy of the circulation unit, the fresh air handling unit can supplement and mix in air with a different humidity value to neutralize the humidity inside the circulation unit and help the circulation unit adjust the air temperature inside to the set value, thereby reducing the impact of external weather changes on the air in the terminal room.

[0019] In some implementations, the fresh air cooling source unit uses water as a carrier to connect to the cooling capacity of the fresh air heat exchanger. The fresh air cooling source unit pre-adjusts the water to a set temperature value. The fresh air heat exchanger is equipped with a first electric valve for controlling the water flow rate. Based on the air temperature value inside the fresh air unit obtained by the fresh air temperature sensor, the fresh air cooling source unit adjusts the water temperature and the water flow rate entering the fresh air heat exchanger. The circulating chiller unit uses another type of water as a carrier to connect to the circulating heat exchanger for cooling capacity. The circulating chiller unit pre-adjusts the other water to a set temperature value. The circulating heat exchanger is equipped with a second electric valve for controlling the water flow rate. Based on the air temperature value obtained by the circulating temperature sensor in the circulating unit, the circulating chiller unit adjusts the temperature of the other water and the flow rate of the other water entering the circulating heat exchanger.

[0020] Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. Compared with traditional air conditioners that use Freon as a heat absorption medium, this high-precision temperature and humidity control system uses a fresh air cooling source unit and a circulating cooling source unit to pre-adjust the water to the set temperature value, and uses water as a heat absorption medium to achieve continuous, real-time and stable regulation of air temperature and humidity; 2. Compared to traditional air conditioners that use Freon as a heat absorber, this high-precision temperature and humidity control system uses water as a heat absorber, which can regulate the air passing through the fresh air heat exchanger and the circulating heat exchanger by finely and accurately controlling the water temperature. 3. Because the fresh air cooling unit and the circulating cooling unit pre-adjust the water temperature, the impact on air temperature control can be further reduced when the outdoor weather, temperature, and humidity change drastically. 4. By adjusting the water temperature and the flow rate into the fresh air heat exchanger or circulating heat exchanger through the fresh air cooling source unit and the circulating air cooling source unit, the air temperature can be adjusted more precisely. 5. By adjusting the water temperature entering the circulating heat exchanger to be close to the room temperature, compared to using chilled water to enter the circulating heat exchanger, warm water close to the room temperature is used to avoid water temperature fluctuations affecting the terminal room temperature, so that the temperature in the terminal room can be kept stable and constant. 6. Compared to traditional air conditioners, it can still regulate air temperature even when the demand for air conditioning is less than the minimum compressor operating load.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the following description is provided with reference to the accompanying drawings.

[0025] like Figures 1 to 9 As shown, a high-precision temperature and humidity control system for workshops and laboratories includes: The circulating unit 2 is a space that restricts the range of air movement. The circulating unit 2 is equipped with a circulating heat exchanger 21 and a circulating temperature sensor. The circulating heat exchanger 21 is connected to the cooling capacity of the circulating cold source host, and the circulating temperature sensor is used to monitor the air temperature inside the circulating unit 2. Terminal room 3, with return air wall 35 around its perimeter, return air wall 35 with return air duct 34 connected to the head end of circulation unit 2, return air inlet 36 at the bottom of return air wall 35 connecting to the bottom of terminal room 3, and the end of circulation unit 2 connected to terminal room 3. After the air temperature and humidity in the circulating unit 2 are adjusted to the set temperature by the circulating heat exchanger 21, the air is delivered from the end of the circulating unit 2 to the terminal room 3 to regulate the temperature and humidity of the terminal room 3. The air in the terminal room 3 enters the return air wall 35 through the return air inlet 36 and flows back to the circulating unit 2 so that the circulating heat exchanger 21 can provide temperature and humidity regulation. The return air wall 35 and the air flowing inside it are used to insulate the terminal room 3 from the outdoor space.

[0026] When outdoor weather, temperature, and humidity change drastically, or when there is a temperature difference between the outdoor environment and the terminal room 3, the return air wall 35 isolates the terminal room 3 from the outdoor space. This prevents outdoor weather from affecting the temperature inside the terminal room 3, improves the accuracy and stability of the air temperature control in the terminal room 3 by the recirculation unit 2, and reduces the temperature difference in various parts of the terminal room 3, especially around the interior walls. Since the air in the terminal room 3 returns to the recirculation unit 2 through the return air wall 35, the temperature of the return air wall 35 is close to the temperature inside the terminal room 3, further reducing the impact of outdoor air temperature on the terminal room 3.

[0027] In some embodiments, the terminal room 3 is provided with a microporous floor 4, and a basement 41 is provided below the microporous floor 4. By utilizing the density difference between air at different temperatures, the low-temperature air in the terminal room 3 leaks into the basement 41 and does not accumulate on the ground. The return air vent 36 is provided in the basement 41; thereby avoiding the accumulation of low-temperature air on the ground and reducing the air temperature difference at different heights in the terminal room 3.

[0028] In some embodiments, a plurality of exhaust channels 42 are arranged at the bottom of the underground layer 41, and an underground fan 43 is provided at intervals in each exhaust channel 42. After the low-temperature air in the underground layer 41 sinks into the exhaust channel 42, the underground fan 43 sends the air in the exhaust channel 42 to the return air vent 36. This allows the air falling into the underground layer 41 to be delivered to the return air vent 36 more efficiently and enter the return air wall 35, thereby preventing the low-temperature air from accumulating in the underground layer 41.

[0029] In some embodiments, room temperature and humidity sensors are installed at different height positions of the terminal room 3. The end of the circulation unit 2 is connected to the top of the terminal room 3. An air cooling capacity control valve 27 is installed at the connection between the circulation unit 2 and the terminal room 3 to control the amount of air input into the terminal room 3 by the circulation unit 2 according to the density difference between air at different temperatures, thereby regulating the temperature at different heights of the terminal room 3.

[0030] Therefore, when cooling the terminal room 3, cold air enters through the top of the terminal room 3, and the air can fill the entire terminal room 3 by falling, thereby reducing the density difference between air at different temperatures and the resulting temperature difference at different heights. Furthermore, auxiliary fans 37 are spaced apart within the return air wall 35 to transport air upwards. The auxiliary fans 37 enable the cold air falling into the interlayer 31 to be returned to the recirculation unit 2 more efficiently through the return air wall 35.

[0031] In some embodiments, a mezzanine 31 is provided at the top of the terminal room 3, and the end of the circulation unit 2 is connected to the top of the mezzanine 31 so that the circulation unit 2 delivers air and fills the mezzanine 31. The bottom wall of the mezzanine 31 is a microporous aluminum plate 32 connected to the terminal room 3. By utilizing the density difference between air at different temperatures, the cold air in the mezzanine 31 sinks and covers the microporous aluminum plate 32. Subsequently, the cold air passes through the microporous aluminum plate 32 and falls into the terminal room 3, thereby dispersing the cold air and uniformly covering all areas of the terminal room 3, further reducing the deviation between the various spaces in the terminal room 3.

[0032] In some embodiments, the microporous aluminum plate 32 array is provided with a plurality of air compressors 33. The air compressors 33 are used to press the air in the interlayer 31 down to the bottom of the terminal room 3 and fill the terminal room 3. A temperature and humidity sensor is provided below the air compressors 33. By independently controlling the wind speed of each air compressor 33, the temperature of each area of ​​the terminal room 3 can be regulated, thereby achieving more precise temperature regulation of each part of the terminal room 3, so as to further reduce the deviation between the various spaces of the terminal room 3.

[0033] In some embodiments, when an object 5 is provided in the terminal room 3, the object 5 may be a large-area object such as equipment, workstation, or material cabinet in the terminal room 3. A guide plate 51 is provided on the top surface of object 5. The periphery of the guide plate 51 is provided with an arc surface. A guide wing 52 is installed on the guide plate 51 and is located next to the arc surface and tilted inward. The guide wing 52 is provided with a guide arc surface 53. The middle part of the guide arc surface 53 is at the same height as the guide plate 51. When the air in the interlayer 31 hits the guide plate 51 and disperses outward, the guide arc surface 53 will make the outward dispersed air flow downward along the side wall of object 5, so as to reduce the interference with the air flow around object 5. The top wall of the guide wing 52 is provided with an outwardly curved outer guide surface 54. When the air in the interlayer 31 hits the top of the guide wing 52, the airflow passes over the outside of the guide wing 52, so as to avoid interfering with the airflow around the guide wing 52. A deflector column 55 is provided below the guide wing 52 to prevent the airflow from passing over the guide wing 52 and forming a vortex that would interfere with the airflow around it. The airflow disturbed by the deflector column 55 is driven down by the airflow around it. Therefore, reducing the airflow from impacting object 5 will cause interference to the air around object 5.

[0034] In some embodiments, the high-precision temperature and humidity control system for workshops and laboratories further includes a fresh air unit 1, which is another space that restricts the range of air movement. A fresh air duct 12 is provided at the beginning of the fresh air unit 1, and the end of the fresh air unit 1 is connected to the beginning of the circulation unit 2.

[0035] Furthermore, the fresh air unit 1 is equipped with: The fresh air temperature sensor and the fresh air heat exchanger 11 are used to monitor the air temperature inside the fresh air unit 1. The fresh air heat exchanger 11 is connected to the cooling capacity of the fresh air cold source unit. After the outdoor air enters the fresh air unit 1 through the fresh air duct 12, it passes through the fresh air heat exchanger 11 and the fresh air temperature sensor to perform initial temperature regulation. After that, the air in the fresh air unit 1 enters the circulation unit 2. At this time, the circulation heat exchanger 21 and the circulation temperature sensor perform precise air regulation. Fresh air filter 13 is used to purify the air entering from the fresh air duct 12; The fresh air humidity sensor is used to monitor the humidity of the air entering from the fresh air duct 12. The fresh air heat exchanger 11 removes the heat from the air and condenses the moisture in the air to adjust the humidity of the air. The fresh air heating module 14 is used to heat the air when the air temperature is lower than the set value in order to reduce the air humidity, or when the air temperature entering from the fresh air duct 12 is lower than the set value. Fresh air unit 15 is used to push the air in fresh air unit 1 into circulation unit 2 to improve the efficiency of air entering circulation unit 2 from fresh air unit 1.

[0036] Before entering the terminal room 3, outdoor air enters the fresh air unit 1 through the fresh air duct 12. The air temperature information inside the fresh air unit 1 is obtained by the fresh air temperature sensor, and the fresh air cooling source host delivers cooling capacity to the fresh air heat exchanger 11 to initially regulate the air to the set range. After that, the air is delivered to the circulation unit 2. The air temperature information inside the circulation unit 2 is obtained by the circulation temperature sensor, and the circulation cooling source host delivers cooling capacity to the circulation heat exchanger 21 to finely adjust the air temperature a second time. Finally, the air is delivered to the terminal room 3. Therefore, the air temperature entering the terminal room 3 can be regulated with high precision.

[0037] Since the air in the terminal room 3 can be returned to the circulating unit 2 through the return air duct 34, the temperature information of the returned air is obtained through the circulating temperature sensor, and the circulating cold source host is used to deliver cooling capacity to the circulating heat exchanger 21, so as to realize the real-time temperature control of the air in the terminal room 3.

[0038] When the outdoor weather, temperature, and humidity change drastically and affect the temperature regulation efficiency and accuracy of the fresh air handling unit 1, the air in the fresh air handling unit 1 can be regulated a second time by the circulation unit 2 before entering the terminal room 3. In addition, when the outdoor weather, temperature, and humidity change drastically and affect the temperature regulation efficiency and accuracy of the circulation unit 2, the fresh air handling unit 1 can supplement and mix the circulation unit 2 with air of another temperature value to assist the circulation unit 2 in adjusting the temperature of the air inside to the set value, thereby reducing the impact of external weather changes on the air in the terminal room 3. In some embodiments, the circulating unit 2 is further provided with: Recirculating air filter 22 is used to purify the air entering the terminal room 3; The circulating humidity sensor is used to monitor the humidity of the air entering the circulating unit 2. The circulating heat exchanger 21 removes the heat from the air and condenses the moisture in the air, so as to accurately adjust the humidity of the air. The circulating heating module 23 is used to heat the air when the air temperature is lower than the set value in order to reduce the air humidity, or when the air temperature entering the circulating unit 2 is lower than the set value. Circulating fan 24 is used to push the air in the circulating unit 2 into the terminal room 3; Humidifier 26 is used to humidify the air when the air humidity in the circulating unit 2 is lower than the set value.

[0039] Before entering terminal room 3, outdoor air obtains humidity information from the fresh air unit 1 via a fresh air humidity sensor. The fresh air heat exchanger 11 removes heat from the air and condenses the moisture in the air, thus initially adjusting the humidity to the set range. Afterward, the air is delivered to the circulation unit 2, where a circulation humidity sensor obtains humidity information from the circulation unit 2. The circulation heat exchanger 21 removes heat from the air and condenses the moisture in the air, thus finely adjusting the humidity a second time. Finally, the air is delivered to terminal room 3. Therefore, the temperature of the air entering terminal room 3 can be precisely regulated.

[0040] Since the air in the terminal room 3 can be returned to the circulating unit 2 through the return air duct 34, the temperature information of the returned air is obtained through the circulating humidity sensor, and the heat of the air is taken away by the circulating heat exchanger 21 to condense the moisture in the air. When the humidity of the air in the terminal room 3 is too low, the air can be humidified through the humidifier 26 to achieve real-time humidity control of the air in the terminal room 3.

[0041] When drastic changes in outdoor weather, temperature, and humidity affect the dehumidification efficiency and humidity control accuracy of the fresh air handling unit 1, the air inside the fresh air handling unit 1 can be dehumidified a second time by the circulation unit 2 before entering the terminal room 3. In addition, when drastic changes in outdoor weather, temperature, and humidity affect the humidity control efficiency and temperature control accuracy of the circulation unit 2, the fresh air handling unit 1 can supplement and mix in air with a different humidity value to neutralize the air humidity inside the circulation unit 2, thereby assisting the circulation unit 2 in adjusting the air temperature inside to the set value, thus reducing the impact of external weather changes on the air in the terminal room 3.

[0042] In some embodiments, the fresh air cooling source unit is connected to the fresh air heat exchanger 11 with water as a carrier. The fresh air cooling source unit pre-adjusts the water to a set temperature value. The fresh air heat exchanger 11 is equipped with a first electric valve 16 for controlling the water flow. Based on the air temperature value inside the fresh air unit 1 obtained by the fresh air temperature sensor, the fresh air cooling source unit adjusts the water temperature and the water flow rate entering the fresh air heat exchanger 11.

[0043] The circulating chiller unit is connected to the circulating heat exchanger 21 with another water as a carrier. The circulating chiller unit pre-adjusts the other water to a set temperature value. The circulating heat exchanger 21 is equipped with a second electric valve 25 for controlling the water flow. Based on the air temperature value inside the circulating unit 2 obtained by the circulating temperature sensor, the circulating chiller unit adjusts the temperature of the other water and the flow rate of the other water entering the circulating heat exchanger 21.

[0044] Compared to traditional air conditioners that use Freon as a heat absorber, this high-precision temperature and humidity control system pre-adjusts the water to the set temperature value through the fresh air cooling source unit and the circulating cooling source unit, and uses water as a heat absorber to achieve continuous, real-time and stable regulation of air temperature and humidity.

[0045] In addition, compared with traditional air conditioners that use Freon as a heat-absorbing medium, this high-precision temperature and humidity control system uses water as a heat-absorbing medium, which can regulate the air passing through the fresh air heat exchanger 11 and the circulating heat exchanger 21 by finely and accurately controlling the water temperature.

[0046] Because the fresh air cooling unit and the circulating cooling unit pre-adjust the water temperature, the impact on air temperature control can be further reduced when the outdoor weather, temperature, and humidity change drastically.

[0047] Furthermore, by adjusting the water temperature and flow rate into the fresh air heat exchanger 11 or the circulating heat exchanger 21 through the fresh air chiller and the circulating chiller, more precise air temperature control can be achieved. Simultaneously, by adjusting the water temperature entering the circulating heat exchanger 21 to be close to the room temperature, compared to using chilled water, warm water close to the room temperature is used, avoiding water temperature fluctuations that could affect the temperature of the terminal room 3, thus ensuring a stable and constant temperature within the terminal room 3. Moreover, compared to traditional air conditioners, this also allows for air temperature regulation even when the air demand is lower than the minimum compressor operating load.

[0048] To further explain the stamping equipment with multiple stamping positions described in this specific embodiment, the following examples are provided.

[0049] Example 1 like Figure 1 and 2 As shown, this embodiment provides a high-precision temperature and humidity control system for workshops and laboratories, which includes a circulating unit 2 and a terminal room 3.

[0050] The circulating unit 2 is a space that restricts the range of air movement. The circulating unit 2 is equipped with a circulating heat exchanger 21 and a circulating temperature sensor. The circulating cold source host is connected to the circulating heat exchanger 21 with refrigerant as the carrier. The circulating temperature sensor is used to monitor the air temperature inside the circulating unit 2.

[0051] The terminal room 3 is provided with a return air wall 35 around its perimeter. The return air wall 35 is provided with a return air duct 34 that is connected to the head end of the circulating unit 2. The bottom of the return air wall 35 is provided with a return air inlet 36 that connects to the bottom of the terminal room 3. The end of the circulating unit 2 is connected to the terminal room 3.

[0052] After the circulating heat exchanger 21 adjusts the air temperature in the circulating unit 2 to the set temperature, it delivers the air from the end of the circulating unit 2 to the terminal room 3 to regulate the temperature and humidity of the terminal room 3. The air in the terminal room 3 enters the return air wall 35 through the return air inlet 36 and flows back to the circulating unit 2 so that the circulating heat exchanger 21 can provide temperature and humidity regulation. The return air wall 35 and the air flowing inside it are used to insulate the terminal room 3 from the outdoor space.

[0053] Example 2 like Figure 1 , 2 As shown in Figures 8 and 9, this embodiment provides a high-precision temperature and humidity control system for workshops and laboratories, which includes a fresh air unit 1, a circulation unit 2, and a terminal room 3.

[0054] The fresh air handling unit 1 is a space that restricts the range of air movement. The fresh air handling unit 1 is equipped with a fresh air heat exchanger 11, a fresh air temperature sensor, a fresh air filter 13, a fresh air humidity sensor, a fresh air heating module 14, and a fresh air fan 15.

[0055] The fresh air cooling unit connects to the fresh air heat exchanger 11 using water as a carrier. The unit pre-adjusts the water to a set temperature. The heat exchanger 11 is equipped with a first electric valve 16 to control the water flow. Based on the air temperature inside the fresh air unit 1 obtained from the fresh air temperature sensor, the cooling unit adjusts the water temperature and the water flow rate into the heat exchanger 11. A fresh air duct 12 is located at the beginning of the fresh air unit 1. Outdoor air enters the unit through the duct and passes through the heat exchanger 11 and the temperature sensor for initial temperature regulation. The temperature sensor monitors the air temperature inside the unit. A fresh air filter 13 purifies the air entering through the duct 12. A circulating temperature sensor monitors the humidity of the air entering through the duct 12. The heat from the air is removed by the heat exchanger 11, causing moisture to condense and thus adjusting the humidity. When the air temperature is lower than the set value to reduce air humidity, or when the air temperature entering from the fresh air duct 12 is lower than the set value, the fresh air heating module 14 is used to heat the air. The fresh air unit 15 is used to push the air in the fresh air unit 1 into the circulation unit 2.

[0056] The circulating unit 2 is another space that restricts the range of air movement. The circulating unit 2 is equipped with a circulating heat exchanger 21, a circulating temperature sensor, a circulating air filter 22, a circulating humidity sensor, a circulating heating module 23, a circulating fan 24, and a humidifier 26.

[0057] The circulating chiller unit connects to the circulating heat exchanger 21 via another water source. The circulating chiller unit pre-adjusts the other water to a set temperature. The circulating heat exchanger 21 is equipped with a second electric valve 25 to control the water flow. Based on the air temperature value inside the circulating unit 2 obtained from the circulating temperature sensor, the circulating chiller unit adjusts the temperature and flow rate of the other water entering the circulating heat exchanger 21. The first end of the circulating unit 2 is connected to the end of the fresh air handling unit 1. After air enters the circulating unit 2 from the fresh air handling unit 1, it passes through the circulating heat exchanger 21 and the circulating temperature sensor to achieve precise air conditioning. The circulating temperature sensor monitors the air temperature inside the circulating unit 2. The circulating air filter 22 purifies the air entering the terminal room 3. The circulating temperature sensor monitors the humidity of the air entering the circulating unit 2. The circulating heat exchanger 21 removes heat from the air, causing moisture to condense, thus precisely adjusting the air humidity. When the air temperature is lowered below a set value to reduce air humidity, or when the air temperature entering the circulation unit 2 is lower than a set value, the circulation heating module 23 is used to heat the air. The circulation fan 24 is used to push the air in the circulation unit 2 into the terminal room 3. When the air humidity in the circulation unit 2 is lower than a set value, the humidifier 26 is used to humidify the air.

[0058] A mezzanine 31 is provided at the top of the terminal room 3. The end of the circulation unit 2 is connected to the top of the mezzanine 31 so that the circulation unit 2 can deliver air and fill the mezzanine 31. The bottom wall of the mezzanine 31 is a microporous aluminum plate 32 connected to the terminal room 3. The microporous aluminum plate 32 is arrayed with several air compressors 33 that blow air vertically downwards into the terminal room 3. The air compressors 33 are used to press the air in the mezzanine 31 downwards and fill the terminal room 3. The microporous aluminum plate 32 is provided with ventilation holes corresponding to the positions of the air compressors 33. The microporous aluminum plate 32 can be replaced by other partitions, but the ventilation holes corresponding to the positions of the air compressors 33 are the same. A temperature and humidity sensor below the air compressors 33 divides the terminal room 3 into several zones by adjusting the air speed of the air compressors 33, and each zone is controlled independently to achieve uniform room temperature.

[0059] By utilizing the density difference between air at different temperatures, the cold air in the interlayer 31 sinks and fills the microporous aluminum plate 32. Then, the cold air passes through the microporous aluminum plate 32 and falls into the terminal room 3. At this time, the microporous aluminum plate 32 disperses the cold air and evenly covers the area of ​​the terminal room 3.

[0060] Temperature and humidity sensors are installed at different heights in terminal room 3 and mezzanine 31. An air cooling capacity control valve 27 is installed at the connection between circulating unit 2 and mezzanine 31 to monitor the air temperature and humidity at different heights in terminal room 3 and mezzanine 31, and adjust the air flow rate entering mezzanine 31 accordingly.

[0061] The terminal room 3 is provided with a return air duct 34 connected to the first end of the circulating unit 2. The outer periphery of the terminal room 3 is provided with a return air wall 35 connected to the return air duct 34. The bottom of the return air wall 35 is provided with a return air inlet 36. The air in the terminal room 3 enters the return air wall 35 through the return air inlet 36 and flows back to the circulating unit 2, so that the return air wall 35 insulates the terminal room 3 from the outdoor space.

[0062] The following is a description of the operation of the high-precision temperature and humidity control system described in this embodiment.

[0063] 1. Adjust air temperature Before entering the terminal room 3, outdoor air enters the fresh air unit 1 through the fresh air duct 12. At this time, the air temperature information inside the fresh air unit 1 is obtained through the fresh air temperature sensor, and the fresh air cooling source host supplies cooling capacity (i.e., water) to the fresh air heat exchanger 11 to initially adjust the air to the set range. The air temperature can be adjusted by controlling the water temperature and water flow rate. After that, the air is sent to the circulation unit 2. The air temperature information inside the circulation unit 2 is obtained through the circulation temperature sensor, and the circulation cooling source host supplies cooling capacity to the circulation heat exchanger 21 to finely adjust the air temperature setting for the second time. The air temperature can be adjusted by controlling another water temperature and another water flow rate. Finally, the air is sent to the interlayer 31 of the terminal room 3 for stacking. The air compressor 33 presses down the air in the interlayer 31 and fills the terminal room 3. The temperature and humidity sensor below the air compressor 33 divides the terminal room 3 into several areas by adjusting the air speed of the air compressor 33, and each area is controlled independently to achieve room temperature uniformity control. When the outdoor weather, temperature, and humidity change drastically and affect the temperature regulation efficiency and accuracy of the circulating unit 2, the fresh air unit 1 can supplement and mix in air of another temperature value to assist the circulating unit 2 in adjusting the temperature of the air inside to the set value.

[0064] Air in terminal room 3 enters return air wall 35 through return air inlet 36 and is transported back to the beginning of circulating unit 2. The return air wall 35 and the air flowing inside it are used to insulate terminal room 3 from the outdoor space. At this time, the temperature information of the returned air is obtained through circulating temperature sensor, and the circulating cold source host is used to supply cooling capacity to circulating heat exchanger 21 to realize real-time temperature control of air in terminal room 3.

[0065] 2. Regulate air humidity Before entering terminal room 3, outdoor air is subjected to a process where a fresh air temperature sensor obtains humidity information from the fresh air handling unit 1. The fresh air heat exchanger 11 removes heat from the air, causing condensation and thus adjusting the humidity to a set range. The air is then transported to the circulation unit 2, where a circulation temperature sensor obtains humidity information. The circulation heat exchanger 21 removes heat from the air, causing condensation and thus further refining the humidity setting. Finally, the air is transported to terminal room 3. When the air temperature is lowered below a set value to reduce humidity, or when the air temperature entering from the fresh air duct 12 is lower than a set value, the fresh air heating module 14 heats the air. Similarly, when the air temperature is lowered below a set value to reduce humidity, or when the air temperature entering the circulation unit 2 is lower than a set value, the circulation heating module 23 heats the air.

[0066] Air in terminal room 3 can be returned to circulating unit 2 through return air duct 34. At this time, the temperature information of the returned air is obtained through a circulating temperature sensor, and the heat of the air is removed by the circulating heat exchanger 21, causing moisture to condense. When the humidity of the air entering terminal room 3 is too low, humidifier 26 can be used to humidify the air, thereby achieving real-time humidity control of the air in terminal room 3. When drastic changes in outdoor weather, temperature, and humidity affect the humidity control efficiency and temperature control accuracy of circulating unit 2, fresh air unit 1 can supplement and mix in air with a different humidity level to neutralize the humidity inside circulating unit 2, thus assisting circulating unit 2 in adjusting the air temperature to the set value.

[0067] Example 3 like Figure 3 , 4 As shown in Figures 5, 8, and 9, this embodiment provides a high-precision temperature and humidity control system for workshops and laboratories, which includes a fresh air unit 1, a circulation unit 2, and a terminal room 3.

[0068] The fresh air handling unit 1 is a space that restricts the range of air movement. The fresh air handling unit 1 is equipped with a fresh air heat exchanger 11, a fresh air temperature sensor, a fresh air filter 13, a fresh air temperature sensor, a fresh air heating module 14, and a fresh air fan 15.

[0069] The fresh air cooling unit connects to the fresh air heat exchanger 11 using water as a carrier. The unit pre-adjusts the water to a set temperature. The heat exchanger 11 is equipped with a first electric valve 16 to control the water flow. Based on the air temperature inside the fresh air unit 1 obtained from the fresh air temperature sensor, the cooling unit adjusts the water temperature and the water flow rate into the heat exchanger 11. A fresh air duct 12 is located at the beginning of the fresh air unit 1. Outdoor air enters the unit through the duct and passes through the heat exchanger 11 and the temperature sensor for initial temperature regulation. The temperature sensor monitors the air temperature inside the unit. A circulating air filter 22 purifies the air entering through the duct 12, and a circulating temperature sensor monitors the humidity. The humidity is adjusted by condensing the moisture in the air as the heat is removed by the heat exchanger 11. When the air temperature is lower than the set value to reduce air humidity, or when the air temperature entering from the fresh air duct 12 is lower than the set value, the fresh air heating module 14 is used to heat the air. The fresh air unit 15 is used to push the air in the fresh air unit 1 into the circulation unit 2.

[0070] The circulating unit 2 is another space that restricts the range of air movement. The circulating unit 2 is equipped with a circulating heat exchanger 21, a circulating temperature sensor, a circulating air filter 22, a circulating heating module 23, a circulating fan 24, and a humidifier 26.

[0071] The circulating chiller unit connects to the circulating heat exchanger 21 via another water source. The circulating chiller unit pre-adjusts the other water to a set temperature. The circulating heat exchanger 21 is equipped with a second electric valve 25 to control the water flow. Based on the air temperature value inside the circulating unit 2 obtained from the circulating temperature sensor, the circulating chiller unit adjusts the temperature and flow rate of the other water entering the circulating heat exchanger 21. The first end of the circulating unit 2 is connected to the end of the fresh air handling unit 1. After air enters the circulating unit 2 from the fresh air handling unit 1, it passes through the circulating heat exchanger 21 and the circulating temperature sensor to achieve precise air conditioning. The circulating temperature sensor monitors the air temperature inside the circulating unit 2. The circulating air filter 22 purifies the air entering the terminal room 3. The circulating temperature sensor monitors the humidity of the air entering the circulating unit 2. The circulating heat exchanger 21 removes heat from the air, causing moisture to condense, thus precisely adjusting the air humidity. When the air temperature is lowered below a set value to reduce air humidity, or when the air temperature entering the circulation unit 2 is lower than a set value, the circulation heating module 23 is used to heat the air. The circulation fan 24 is used to push the air in the circulation unit 2 into the terminal room 3. When the air humidity in the circulation unit 2 is lower than a set value, the humidifier 26 is used to humidify the air.

[0072] A mezzanine 31 is provided at the top of the terminal room 3. The end of the circulation unit 2 is connected to the top of the mezzanine 31 so that the circulation unit 2 can deliver air and fill the mezzanine 31. The bottom wall of the mezzanine 31 is a microporous aluminum plate 32 connected to the terminal room 3. By utilizing the density difference between air at different temperatures, the cold air in the mezzanine 31 sinks and covers the microporous aluminum plate 32. Then, the cold air passes through the microporous aluminum plate 32 and falls into the terminal room 3. At this time, the microporous aluminum plate 32 disperses the cold air and evenly covers the area of ​​the terminal room 3.

[0073] Temperature and humidity sensors are installed at different heights in terminal room 3 and mezzanine 31. An air cooling capacity control valve 27 is installed at the connection between circulating unit 2 and mezzanine 31 to monitor the air temperature and humidity at different heights in terminal room 3 and mezzanine 31, and adjust the air flow rate entering mezzanine 31 accordingly.

[0074] The terminal room 3 is provided with a return air wall 35 around its perimeter. The return air wall 35 is provided with a return air duct 34 connected to the head end of the circulating unit 2. The bottom of the return air wall 35 is provided with a return air inlet 36 that connects to the bottom of the terminal room 3.

[0075] The following is a description of the operation of the high-precision temperature and humidity control system described in this embodiment.

[0076] 1. Adjust air temperature Before entering the terminal room 3, outdoor air enters the fresh air unit 1 through the fresh air duct 12. At this time, the air temperature information inside the fresh air unit 1 is obtained through the fresh air temperature sensor, and the fresh air cooling source host supplies cooling capacity (i.e., water) to the fresh air heat exchanger 11 to initially adjust the air to the set range. The air temperature can be adjusted by controlling the water temperature and water flow rate. After that, the air is sent to the circulation unit 2. The air temperature information inside the circulation unit 2 is obtained through the circulation temperature sensor, and the circulation cooling source host supplies cooling capacity to the circulation heat exchanger 21 to finely adjust the air temperature for the second time. The air temperature can be adjusted by controlling another water temperature and another water flow rate. Finally, the air is sent to the interlayer 31 of the terminal room 3. At this time, the density difference between air at different temperatures is used to make the cold air in the interlayer 31 sink and cover the microporous aluminum plate 32. Then the cold air falls through the microporous aluminum plate 32 to the terminal room 3. At this time, the microporous aluminum plate 32 disperses the cold air and evenly covers the area of ​​the terminal room 3. When the outdoor weather, temperature, and humidity change drastically and affect the temperature regulation efficiency and accuracy of the circulating unit 2, the fresh air unit 1 can supplement and mix in air of another temperature value to assist the circulating unit 2 in adjusting the temperature of the air inside to the set value.

[0077] Air in terminal room 3 enters return air wall 35 through return air inlet 36 and is transported back to the beginning of circulating unit 2. The return air wall 35 and the air flowing inside it are used to insulate terminal room 3 from the outdoor space. At this time, the temperature information of the returned air is obtained through circulating temperature sensor, and the circulating cold source host is used to supply cooling capacity to circulating heat exchanger 21 to realize real-time temperature control of air in terminal room 3.

[0078] 2. Regulate air humidity Before entering terminal room 3, outdoor air is subjected to a process where a fresh air temperature sensor obtains humidity information from the fresh air handling unit 1. The fresh air heat exchanger 11 removes heat from the air, causing condensation and thus adjusting the humidity to a set range. The air is then transported to the circulation unit 2, where a circulation temperature sensor obtains humidity information. The circulation heat exchanger 21 removes heat from the air, causing condensation and thus further refining the humidity setting. Finally, the air is transported to terminal room 3. When the air temperature is lowered below a set value to reduce humidity, or when the air temperature entering from the fresh air duct 12 is lower than a set value, the fresh air heating module 14 heats the air. Similarly, when the air temperature is lowered below a set value to reduce humidity, or when the air temperature entering the circulation unit 2 is lower than a set value, the circulation heating module 23 heats the air.

[0079] Air in terminal room 3 can be returned to circulating unit 2 through return air duct 34. At this time, the temperature information of the returned air is obtained through a circulating temperature sensor, and the heat of the air is removed by the circulating heat exchanger 21, causing moisture to condense. When the humidity of the air entering terminal room 3 is too low, humidifier 26 can be used to humidify the air, thereby achieving real-time humidity control of the air in terminal room 3. When drastic changes in outdoor weather, temperature, and humidity affect the humidity control efficiency and temperature control accuracy of circulating unit 2, fresh air unit 1 can supplement and mix in air with a different humidity level to neutralize the humidity inside circulating unit 2, thus assisting circulating unit 2 in adjusting the air temperature to the set value.

[0080] Example 4 like Figure 6 As shown, this embodiment is a high-precision temperature and humidity control system applied in laboratories and workshops, which includes all the features of embodiments 1, 2 or 3.

[0081] Meanwhile, terminal room 3 is equipped with a microporous floor 4, and a basement 41 is located below the microporous floor 4. Utilizing the density difference between air at different temperatures, the low-temperature air in terminal room 3 leaks into the basement 41 and does not accumulate on the ground. Return air vents 36 are located within the basement 41. Several exhaust channels 42 are arranged at the bottom of the basement 41, and underground fans 43 are spaced apart within each exhaust channel 42. After the low-temperature air in the basement 41 sinks into the exhaust channel 42, the underground fans 43 deliver the air from the exhaust channel 42 to the return air vent 36. This ensures that the air falling into the basement 41 can be more efficiently transported to the return air vent 36 and enter the return air wall 35. Assisted fans 37, which transport air upwards, are spaced apart within the return air wall 35.

[0082] Example 5 like Figure 7 As shown, this embodiment is a high-precision temperature and humidity control system applied in laboratories and workshops, which includes all the features of embodiments 1, 2, 3 or 4.

[0083] In addition, when an object 5 is set in the terminal room 3, the object 5 can be a large-area object such as equipment, workstation, or material cabinet in the terminal room 3. A guide plate 51 is provided on the top surface of object 5. The periphery of the guide plate 51 is provided with an arc surface. A guide wing 52 is installed on the guide plate 51 and is located next to the arc surface and tilted inward. The guide wing 52 is provided with a guide arc surface 53. The middle part of the guide arc surface 53 is at the same height as the guide plate 51. When the air in the interlayer 31 hits the guide plate 51 and disperses outward, the guide arc surface 53 will make the outward dispersed air flow downward along the side wall of object 5, so as to reduce the interference with the air flow around object 5. The top wall of the guide wing 52 is provided with an outwardly curved outer guide surface 54. When the air in the interlayer 31 hits the top of the guide wing 52, the airflow passes over the outside of the guide wing 52, so as to avoid interfering with the airflow around the guide wing 52. A deflector column 55 is provided below the guide wing 52 to prevent the airflow from passing over the guide wing 52 and forming a vortex that would interfere with the airflow around it. The airflow disturbed by the deflector column 55 is driven down by the airflow around it. Therefore, reducing the airflow from impacting object 5 will cause interference to the air around object 5.
