Description

Technical Field

[0001] The present application relates to the field of purification air conditioning control technology for workshops, and in particular to a self-regulating purification air conditioning system and feedback system for sterile workshops. Background Art

[0002] In sterile workshops, especially in sterile production rooms in biochemical and chemical fields such as pharmaceuticals and biological experiments, it is crucial to ensure the cleanliness of the air inside the workshop and the stability of temperature and humidity. These environmental factors are key factors that directly affect the quality and efficiency of the workshop product production process.

[0003] Under existing technology, regulating environmental factors such as temperature, humidity, and cleanliness in a workshop requires the use of a purification and air conditioning system equipped with a PID controller and various sensors. By analyzing data from temperature and humidity sensors, the air volume and the power of the heating and humidification equipment are adjusted in a feedback manner to maintain the set temperature and humidity. However, it is well known that feedback adjustments using PID controllers have an adjustment cycle, making it impossible to effectively and quickly adjust the temperature and humidity significantly. In other words, purification and air conditioning systems equipped with PID controllers are unable to respond to emergencies and have obvious limitations when the workshop environment changes drastically.

[0004] In view of the above-mentioned related technologies, the inventors believe that the ability of the purification air conditioning in the sterile workshop to cope with drastic environmental changes can be improved by improving the pipe network connection method or air conditioning component structure of the purification air conditioning system. Summary of the Invention

[0005] In order to improve the ability of purification air conditioning to cope with drastic changes in the environment, the present invention provides a self-regulating purification air conditioning system and a feedback system for a sterile workshop.

[0006] On the one hand, the present invention provides a self-regulating purification air-conditioning system for a sterile workshop, which adopts the following technical solutions:

[0007] A self-regulating purification air conditioning system for a sterile workshop includes an air supply duct, a return air duct, a water delivery component, a heating component, a humidifying component, and a fan. The air supply duct and the return air duct include a plurality of ducts, and the air supply ducts correspond to the return air ducts one by one. The system also includes:

[0008] A steam bin is provided on one side of the humidifying element, connected to the humidifying element, and used for temporarily storing steam. The steam bin is connected to a steam pipe;

[0009] A hot water tank is provided on one side of the heating element, connected to the heating element, and used for temporarily storing hot water. The hot water tank is connected to a hot water pipe;

[0010] A cold water tank is provided on one side of the water delivery member, connected to the water delivery member, and used for temporarily storing cold water. The cold water tank is connected to a cold water pipeline.

[0011] By adopting the above technical solution, on the basis of the existing air-conditioning structure consisting of supply air ducts, return air ducts, water delivery components, heating components, humidification components and fans, multiple groups of supply air ducts and return air ducts are set up, and each group of ducts is connected to the interior of the workshop, providing multiple parallel connection channels between the purification air-conditioning system and the environmental space in the workshop; specifically, each air-conditioning outlet in the workshop is connected through a unified pipe network, and one pipe network is set up for each workshop. The corresponding pipe network of one workshop is connected to multiple supply air ducts and return air ducts at the same time, ensuring that each supply air duct and return air duct can act on each air-conditioning outlet in the workshop;

[0012] In actual application, two groups of supply air ducts and return air ducts are usually set at both ends of each air conditioner. The two groups of ducts are used for primary air supply, primary return air, secondary air supply and secondary return air respectively. After the purification air conditioner in the workshop is turned on, the fan supply air first supplies air, and then turns on the exhaust air after the preset time period of air supply, so that the air in the workshop returns to the purification air conditioning system through the primary return air duct. The purification system compares the temperature and humidity of the return air flow detected by the workshop with the preset temperature and humidity values ​​of the technicians based on the temperature sensor and humidity sensor inside the workshop, or the temperature and humidity of the extracted return air flow, and turns on the heating element and humidifying element based on the numerical comparison results. If there is a lack of humidity in the air, the humidifying element is turned on, and if the temperature exceeds the preset stable range, the heating element is turned on to purify and filter the gas and discharge it again to Inside the workshop, the exhaust gas is heated and humidified, and the above process is repeated in the secondary air supply duct and the secondary return air duct, thereby improving the stability of the workshop's internal environment. When there are drastic environmental changes, multiple air supply ducts and return air ducts operate simultaneously, and the original air purification mode of running once and twice in sequence is replaced with the simultaneous operation of the primary and secondary air supply ducts, and the simultaneous operation of the primary and secondary return air ducts. This greatly improves the gas exchange efficiency of the workshop's internal space in a short period of time. When the temperature and humidity need to be adjusted significantly, high accuracy is no longer important. Therefore, changing the secondary cycle to a single cycle to improve efficiency is feasible and extremely reasonable, and can quickly make up for the difference in the change of the workshop's internal environment.

[0013] In addition, in the above scheme, on the basis of the existing humidifying components, heating components, and water supply components, steam bins, hot water bins, and cold water bins are set up one by one to temporarily store high-temperature steam, high-temperature hot water, and normal-temperature cold water, so that the water source required for heating and humidification can be quickly provided in an emergency; specifically, the steam pipe connects the steam source and the steam bin, the hot water pipe connects the hot water bin and the hot water source, and the cold water pipe connects the cold water bin and the cold water source, and corresponding sensors are set in the steam bin, hot water bin, and cold water bin to detect the water temperature and water volume inside the steam bin, hot water bin, and cold water bin. When the steam source, hot water source, and cold water source are insufficient, the steam source, hot water source, and cold water source will promptly provide steam source and water source of preset temperature.

[0014] Optionally, multiple air supply ducts and return air ducts are interconnected, and valves are provided on the pipe bodies of multiple air supply ducts and return air ducts. The valves of the air supply ducts and return air ducts are both provided at one end of the pipe body close to the workshop.

[0015] By adopting the above technical solution, the valve is set on the pipe body on the basis of connecting the supply air duct and the return air duct inside the purification air conditioning system. That is to say, when the valve is closed, the air conditioning system body inside the purification air conditioning system is still in a state of communication. The primary return air and secondary return air processes can use a set of heating components, humidification components and water supply components, saving design costs.

[0016] Furthermore, the above solution limits the position of the valve, and the valve on the air supply duct for supplying air to the interior of the workshop is set at one end close to the workshop. When the valve is closed, the airflow after the temperature and humidity adjustment of the purification air conditioner is delivered to the interior of the duct body and is ready. When the valve is opened, the airflow can be directly delivered to the interior of the workshop, thereby improving the response speed of the purification air conditioning system and thus improving the handling of emergency situations. Moreover, when a drastic change in the environment requires a rapid response from the purification air conditioning system, multiple air supply ducts need to be opened at the same time. Under the above solution, the gas inside the duct body can directly flow into the workshop.

[0017] In the above scheme, the valve of the return air duct is set near one end of the workshop to prevent the air flow inside the workshop from rushing into the return air duct when the valve is closed; since the secondary return air process is carried out sequentially, after the air flow inside the workshop rushes into the return air duct during the first air supply and first return air process, the air flow after the secondary air supply cannot affect the air flow inside the return air duct. Therefore, it is extremely necessary to set the valve at one end of the duct body near the workshop to prevent the air flow inside the workshop from rushing into.

[0018] Optionally, each of the air supply ducts and each of the return air ducts is provided with a fan.

[0019] By adopting the above technical solution, on the basis of the above-mentioned air supply duct and return air duct connection solution, a fan is set in each duct one by one to provide power for air supply or return in each duct;

[0020] The fans corresponding to the two air supply ducts are a group of supply fans, and the fans corresponding to the two return air ducts are a group of return air fans. Since the air supply ducts and return air ducts inside the purification air conditioner are connected, only one of the air supply fans in a group can be turned on and in working state, and the other can be in a stopped standby state; similarly, only one of the return air fans in a group can be in working state, and the other can be in a stopped standby state.

[0021] First, when one fan is under maintenance, the other fan can be directly switched to working state, realizing maintenance without stopping the machine and ensuring the air purification supply of the sterile workshop; second, more importantly, when the environment changes drastically and the purification air conditioner needs to run quickly and urgently at high power, the two sets of air supply fans are fully opened, and the air with preset temperature and humidity is delivered to the workshop through two air supply ducts, thereby greatly improving the ability of the purification air conditioning system to respond to emergencies. When the external environment changes drastically, the purification air conditioning system can respond in time.

[0022] Optionally, the hot water pipe passes through the steam bin.

[0023] By adopting the above technical solution, the hot water pipe used to transport hot water to the hot water tank is passed through the steam tank, or a hot water pipe of a preset length is reserved in the steam tank. The hot water pipe and the hot water tank are controlled by a solenoid valve. In actual application, the solenoid valve should be set at the connection between the hot water pipe and the hot water tank. When the water temperature in the hot water tank drops to outside the preset temperature range, the solenoid valve opens and the hot gas source transports water.

[0024] As is known to all, under the existing technology, the heating of the hot air source generally adopts the electric heating method. Although the energy consumption is not high compared with other heating methods, it can be further reduced by utilizing the waste heat of steam. In the above scheme, the steam bin is an energy storage component of the heating and humidifying component, which is used to provide hot and humid steam to the inside of the air conditioner to create a hot and humid air environment under special conditions. The low density of steam determines that the heat energy loss of steam is faster than that of hot water. Therefore, more heat is lost from the steam in the steam bin. On this basis, a steam pipe is arranged in the steam bin, and the length of the steam pipe in the steam bin is a preset length, so that enough hot water is stored in the steam bin, so that the steam in the steam bin continuously exchanges heat with the hot water in the hot water pipe, fully utilizing the heat energy originally lost by the steam, maintaining the hot water temperature inside the hot water pipe in the steam bin, reducing the electric heating start-up cycle at the hot water source, and saving energy.

[0025] In actual applications, a temperature sensor should be installed inside the steam bin corresponding to the hot water pipe to detect the hot water temperature inside the hot water pipe in real time to ensure the water temperature of the hot water pipe in the steam bin. When hot water needs to be added to the hot water bin, the solenoid valve is first opened to extract the hot water in the hot water bin and transport the hot water in a section of the hot water pipe inside the steam bin to the hot water bin to realize hot water replacement. The replacement amount is the amount of water in a section of the hot water pipe in the steam bin.

[0026] Optionally, a circulation pipe is provided between the hot water tank and the cold water tank to connect the hot water tank and the cold water tank.

[0027] By adopting the above technical solution, the circulation pipe between the hot water tank and the cold water tank circulates the hot water and cold water inside the hot water tank and the cold water tank to adjust the temperature. The necessity of such a setting lies in that in actual application, the water stored in the hot water tank and the cold water tank is water at a preset temperature, the water in the cold water tank is water at a normal temperature of 18°C-22°C, and the water in the hot water tank is determined according to specific production needs, usually not exceeding 40°C. Therefore, for workshops with more complex environmental requirements, temperature adjustment is required. For example, if a humid environment of 30°C is required in the workshop, the circulation pipes in the cold water tank and the hot water tank need to be connected for temperature adjustment. If the required water temperature is higher, a small amount of water needs to be drawn from the cold water tank and injected into the temperature adjustment chamber of the hot water tank. If the required water temperature is lower, a small amount of water needs to be drawn from the hot water tank and injected into the temperature adjustment chamber of the cold water tank for temperature adjustment.

[0028] Two circulation pipes are provided, one of which connects the cold water tank and the temperature-regulating chamber of the hot water tank, and the other connects the hot water tank and the temperature-regulating chamber of the cold water tank. Water pumps are provided on both circulation pipes to provide water flow transmission power.

[0029] On the one hand, the present invention provides a feedback system for a self-regulating purification air-conditioning system in a sterile workshop, which adopts the following technical solutions:

[0030] A feedback system for a self-regulating purification air-conditioning system in a sterile workshop, comprising a control processing module, wherein the control processing module includes calculation files and execution files, and has data processing, instruction generation and receiving functions, and is applied to the self-regulating purification air-conditioning system;

[0031] The feedback system includes multiple temperature sensors, multiple water level sensors, and multiple humidity sensors, each of which is integrated with a wireless module to send collected information to the control processing module;

[0032] The temperature sensor is arranged in the hot water tank, the cold water tank, the steam tank, the hot water pipe, each of the air supply pipes, each of the return air pipes, and the circulation pipe;

[0033] The water level sensor is arranged in the hot water tank and the cold water tank;

[0034] The humidity sensor is arranged in the steam bin, each of the air supply ducts, and each of the return air ducts.

[0035] By adopting the above technical solution, the control processing module adopts an industrial single-chip microcomputer or a small computer with low performance requirements. It only needs to have the most basic data logic, differential and integral calculations, and the sending, writing, and execution of control instructions. In the above solution, it is used to receive the detection parameters of the temperature sensor, water level sensor, and humidity sensor, and generate instructions based on the numerical calculation results, and transmit them to the component used to specifically execute the instruction results;

[0036] The temperature sensor is the main component for detecting specific temperature changes in the purification air conditioning system, including liquid temperature sensor and gas temperature sensor. The temperature sensors installed in the hot water tank and the cold water tank detect the specific water temperature inside the hot water tank and the cold water tank, and are used to determine whether the water currently stored in the hot water tank needs to be replaced in time. If the water temperature in the hot water tank is lower than the preset temperature value of the technician, the control processing module can replenish the hot water source in time according to the detection data of the temperature sensor; the cold water tank is at room temperature and the temperature is relatively stable and does not need to be replaced. Therefore, the temperature sensor installed in the cold water tank is only used to detect the water temperature of the water temporarily stored in the cold water tank for the above-mentioned cold and hot water temperature adjustment; the temperature sensor installed in the steam The temperature sensor in the steam bin uses a gas sensor to detect the steam temperature of water vapor. Similar to the temperature sensor in the hot water bin, when the steam temperature is lower than the preset temperature range, the control processing module controls the steam source to deliver steam and replenish it in time. The temperature sensors installed in the supply air duct and the return air duct use gas temperature sensors to detect the temperature of the conveying gas in the duct. In real time, it is detected whether the air temperature conveyed in the return air duct and the supply air duct during the primary return air and secondary return air processes is at the preset temperature. The temperature sensor in the circulation duct only serves as a reference and monitoring function. Under normal circumstances, its detected temperature value should be equal to the temperature values ​​in the hot water bin and the cold water bin.

[0037] The water level sensors installed in the hot water tank and the cold water tank in the above scheme are mainly used to detect the storage amount in the cold water tank and the hot water tank. The water level sensors are set at the preset heights of the hot water tank and the cold water tank, and prompts are issued in time when the water level is insufficient. The humidity sensor in the above scheme is used to detect whether the humidity of the primary return air, the secondary return air and the air inside the purification air conditioning system is within the preset value. By detecting and judging the humidity value of the air discharged by the purification air conditioning system, the stability inside the workshop is improved;

[0038] It should be noted that the temperature sensors and humidity sensors installed in the air inlet and return air ducts are more important for detecting the humidity and temperature values ​​of the secondary return air duct and the secondary air inlet duct. The primary return air is a process quantity and only serves as a process reference. It is a process quantity for technicians to visually observe and compare. The secondary return air is the result value of the purification air conditioning system and is the calculation quantity of the above-mentioned control processing module.

[0039] In summary, the temperature sensors, humidity sensors and water level sensors installed in multiple parts of the purification air conditioning system are the numerical basis for the purification air conditioning system to judge the air conditions inside the workshop and the internal conditions of the purification air conditioning system.

[0040] Optionally, it also includes a solenoid valve and a power component;

[0041] The solenoid valve and the power component are all arranged on the steam pipe, the hot water pipe, the cold water pipe, the circulation pipe, the air inlet pipe, and the return air pipe;

[0042] The solenoid valve body and the power component body are both integrated with wireless modules to communicate with the control processing module area and receive instructions from the control processing module. The solenoid valve body switches the valve state, and the power component provides power for conveying air and water flow.

[0043] By adopting the above technical solution, the solenoid valve and the power component serve as specific execution components, mainly executing the instructions generated by the control processing module based on the detection data of multiple sensors. The instructions are sent to the solenoid valve and the power component through the wireless module, and the power component and the solenoid valve specifically execute the instructions; control the opening and closing of the above-mentioned steam pipes, hot water pipes, cold water pipes, circulation pipes, air inlet pipes, and return air pipes;

[0044] In the above scheme, the power parts generally use fans and normal temperature water pumps. The temperature and humidity adjustment inside the purification air conditioner is operated by the front-end heating components, humidification components and water supply components. The fans and normal temperature water pumps only provide transmission power. Therefore, when actually selecting, only pay attention to the power adaptation of the air output and spray volume of the air conditioner.

[0045] Optionally, it also includes an emergency monitoring module;

[0046] The emergency monitoring module is internally integrated with a wireless module, which is connected to the temperature sensor, the humidity sensor, the solenoid valve, the power component, and the control processing module;

[0047] The emergency monitoring module is provided with a logic operator, which internally stores a normal temperature value range and a normal humidity value range. The emergency monitoring module receives the detection values ​​of the temperature sensor and the humidity sensor, and compares them in real time. When the temperature value exceeds the normal temperature value range, or when the humidity value exceeds the normal humidity value range, an emergency signal is sent to the control processing module. The control processing module generates an emergency instruction according to the emergency signal to control the solenoid valve and the power component to change the operating state.

[0048] By adopting the above technical solution, the emergency monitoring module has a wider monitoring value range. The value range stored in it is the normal humidity and normal temperature range inside the workshop. When the humidity and temperature sensor values ​​exceed the normal value range, it indicates that the workshop environment is relatively severe. Moreover, if the purification air conditioning system continues to operate, the value exceeds the normal value range, which indicates that the current environment is extremely severe and relatively abnormal. Therefore, when any of the temperature and humidity detection values ​​are abnormal, the emergency monitoring module sends an emergency signal to the control processing module, so that the control processing module can make emergency processing in time.

[0049] If the temperature value monitored by the temperature sensor exceeds the range, a temperature emergency signal will be sent. If the humidity value monitored by the humidity sensor exceeds the range, a humidity emergency signal will be sent. The control processing module controls the opening and closing states of the solenoid valves related to temperature and humidity or instantly increases the operating power of the power parts according to different emergency signals.

[0050] That is, the technical solution of simultaneously opening the supply air duct and the return air duct to supply air and return air to the interior of the workshop is an emergency solution adopted in an emergency state, which is implemented based on the logical judgment of the monitoring values ​​by the emergency monitoring module.

[0051] In summary, this application includes at least one of the following beneficial technical effects:

[0052] 1. By setting up steam, hot water, and cold water tanks to temporarily store steam, hot water, and cold water respectively, and connecting them to corresponding humidification components, heating components, and water supply components, efficient energy storage and utilization are achieved, keeping energy ready for delivery at any time, effectively improving the response speed of the purification air conditioning system in traditional systems;

[0053] 2. Multiple air supply ducts and return air ducts are set up in a one-to-one correspondence, and airflow distribution is flexibly controlled by valves. The temperature and humidity can be precisely adjusted according to the actual needs of different areas, avoiding the problem of local over-dryness or over-humidity, and significantly improving the stability and uniformity of the sterile workshop environment;

[0054] 3. The design of passing hot water pipes through the steam tank enhances heat exchange efficiency and further optimizes resource utilization. At the same time, the compact structural layout reduces the equipment footprint, facilitates installation and maintenance, and reduces the company's operating costs.

[0058] The following is combined with Figure 1-2 This application is described in further detail.

[0059] The present application embodiment discloses a self-regulating purification air conditioning system for a sterile workshop. Figure 1 A self-regulating purification air-conditioning system for a sterile workshop includes an air supply duct 1, a return air duct 11, a heating chamber 2, a humidifying chamber 31, a normal temperature chamber 3, a fan 25 and multiple filters. The air supply duct 1 and the return air duct 11 extend to the top of the corresponding workshop and serve as the air purification duct opening of the workshop, or are directly connected to the heating and cooling indoor units of the workshop and share an air outlet with the central air-conditioning for heating and cooling to perform air purification, constant temperature, constant humidity and other related work to maintain environmental stability; the heating chamber 2, humidifying chamber 31, normal temperature chamber 3, fan 25 and multiple filters constitute the air-conditioning body of the purification air-conditioning system.

[0060] Reference Figure 1In the above scheme, the air supply duct 1 and the return air duct 11 each include two, and the two air supply ducts 1 are distributed at both ends of the air-conditioning body, one end of which is connected to the air-conditioning body, and air is discharged from the inside of the air-conditioning body; the two air supply ducts 1 are respectively a primary air supply duct 1 and a secondary air supply duct 1, which are used for primary air supply and secondary air supply, respectively; similarly, the two return air ducts 11 are set one-to-one corresponding to the two air supply ducts 1, for primary return air and secondary return air; in this embodiment, the two air supply ducts 1 are connected at one end close to the air-conditioning body, and the two return air ducts 11 are connected at one end close to the air-conditioning body, so that the two groups of air supply ducts 1 and the two groups of return air ducts 11 can share a group of heating components, humidifying components and water supply components inside the air-conditioning body, saving design costs. A solenoid valve 26 is provided at one end of multiple supply air ducts 1 and return air ducts 11 away from the air conditioner body. The solenoid valve 26 controls the connection between the supply air duct 1 and the return air duct 11. Specifically, the solenoid valve 26 should be set at the workshop air outlet and return air outlet of the supply air duct 1 and the return air duct 11. In this embodiment, the solenoid valve 26 is set as close to one end of the workshop as possible so that the supply air duct 1 is filled with the conveying gas from the air conditioner body when it is not connected. When the solenoid valve 26 is turned on, it can directly supply air to the workshop; and the solenoid valve 26 door of the return air outlet is to prevent the workshop gas from entering the return air duct 11 when the valve is not connected, accumulating in the return air duct 11 and unable to be purified.

[0061] Reference Figure 1 In this embodiment, the heating chamber 2 of the air conditioner body is used to heat gas or transport hot water mist to the workshop, the steam chamber 24 is used to transport hot steam to the workshop through the air supply duct 1 for heating and humidification, and the normal temperature chamber 3 is used to transport normal temperature water mist to the workshop. The water flow of the heating chamber 2 and the normal temperature chamber 3 cannot pass through the air supply duct 1. Therefore, in this embodiment, a connecting water supply pipe 12 is set on one side of the heating chamber 2 and the normal temperature chamber 3. The water supply pipe 12 is connected to the sprinkler on the ceiling of the workshop. Unlike the air supply duct 1 and the return air duct 11, the valve on the water supply pipe 12 is set near one end of the air conditioner body to avoid water accumulation inside the pipe when the valve is closed, and the temperature of the water accumulated inside the pipe cannot be controlled.

[0062] Reference Figure 1A hot water tank 22, a cold water tank 21 and a steam tank 24 are provided on one side of the heating tank 2, the normal temperature tank 3 and the humidifying tank 31. The hot water tank 22 stores hot water of a preset temperature, the cold water tank 21 stores water of normal temperature, and the steam tank 24 stores high-temperature steam. Since steam is easy to dissipate heat and heat energy is easy to lose, the steam tank 24 is usually arranged on one side of the humidifying tank 31 and fits the tank wall of the humidifying tank 31 to minimize heat energy loss. The steam tank 24 is connected to a steam pipe 241. The front end of the steam pipe 241 is connected to a steam source to continuously deliver steam of a preset temperature to the steam tank 24. A fan 25 and a solenoid valve 26 are provided on the pipe body of the steam pipe 241. The solenoid valve 26 controls the opening and closing of the steam pipe 241, and the fan 25 provides steam from the front end. The power for conveying water from the source to the steam warehouse 24 is provided; the cold water warehouse 21 is connected with a cold water pipe 211, one end of the cold water pipe 211 is connected with a water source, and the pipe body of the cold water pipe 211 is provided with a solenoid valve 26 and a water pump 251, the solenoid valve 26 is used for the cylinder wall of the cold water pipe 211, and the water pump 251 provides the power for the water source to flow to the cold water warehouse 21; the hot water warehouse 22 is connected with a hot water pipe 221, one end of the hot water pipe 221 is connected with a water source, and the pipe body of the hot water pipe 221 is provided with a solenoid valve 26 and a water pump 251, the solenoid valve 26 is used for the cylinder wall of the hot water pipe 221, and the water pump 251 provides the power for the water source to flow to the hot water warehouse 22.

[0063] Reference Figure 1 A temperature regulating tank 23 is provided inside the hot water tank 22 and the cold water tank 21. The temperature regulating tank 23 is used to adjust the water temperature. The temperature regulating tank 23 inside the hot water tank 22 and the hot water tank 22 body are connected to the heating tank 2 of the air-conditioning body, and the temperature regulating tank 23 inside the cold water tank 21 and the cold water tank 21 body are connected to the normal temperature tank 3 of the air-conditioning body, and transport specific stable water to the inside of the air-conditioning body; a circulation pipe 231 is provided between the hot water tank 22 and the cold water tank 21. The circulation pipe 231 includes two pipes, one connecting the hot water tank 22 and the temperature regulating tank 23 in the cold water tank 21, and the other connecting the cold water tank 21 and the temperature regulating tank 23 in the hot water tank 22. A water pump 251 and a solenoid valve 26 are provided on the pipe body of each circulation pipe 231.

[0064] Reference Figure 1 The cold water pipe 211, the hot water pipe 221, and the steam pipe 241 each include two pipes, one for input and the other for output. Among them, one end of the input end of the hot water pipe 221 extends into the steam bin 24, and forms a pipe network structure in the steam bin 24, so that the pipe part of the hot water pipe 221 in the steam bin 24 can store a certain amount of water, make full use of the steam heat energy that is easily lost, and heat the hot water inside the hot water pipe 221 through heat transfer.

[0065] The implementation principle of a self-regulating purification air-conditioning system for a sterile workshop in an embodiment of the present application is as follows: after the purification air-conditioning in the workshop is turned on, the fan 25 supplies air, and after a preset period of time, the exhaust is turned on, so that the air in the workshop returns to the purification air-conditioning system through the primary return air duct 11. The purification system compares the temperature and humidity of the return air flow detected by the temperature sensor 27 and the humidity sensor 28 inside the workshop, or with the preset temperature and humidity values ​​of the technicians, and turns on heating and humidification based on the numerical comparison results. If there is a lack of humidity in the air, the humidification is turned on, and if the temperature exceeds the preset stable range, the heating element is turned on, and the gas is purified and filtered and then discharged to the interior of the workshop again. The gas discharged in this way is the gas with changed temperature and humidity, and then the above process is repeated in the secondary supply air duct 1 and the secondary return air duct 11 to improve the stability of the internal environment of the workshop; and when there is a drastic environmental change, multiple supply air ducts 1 and return air ducts 11 operate simultaneously, and the original air purification mode of the primary and secondary operations in sequence is changed to the primary supply air duct 1 and the secondary supply air duct 1 operating simultaneously, and the primary return air duct 11 and the secondary return air duct 11 operating simultaneously.

[0066] When there are drastic environmental changes, multiple air supply ducts 1 and return air ducts 11 operate at the same time, and the original air purification mode of running once and twice in sequence is replaced with the simultaneous operation of the primary air supply duct 1 and the secondary air supply duct 1, and the simultaneous operation of the primary return air duct 11 and the secondary return air duct 11. In a short period of time, the gas replacement efficiency in the internal space of the workshop is greatly improved, and the change difference of the internal environment of the workshop is quickly compensated.
