Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving management, and in particular to a system for solving the problems of high energy consumption and easy pollution in preparation rooms outside experimental animal centers. Background Art

[0002] The Laboratory Animal Center is a specialized laboratory facility that integrates animal husbandry, animal experiments, and the preparation and handling of experimental animals. The preparation and handling of experimental animals involves the disposal, sanitary cleaning, and disinfection of waste (cages, bedding, waste feed, etc.).

[0003] The external preparation room is a specific place provided for the preparation and processing of experimental animals. Due to the potential biochemical contamination involved, 24-hour uninterrupted indoor environmental management is usually required.

[0004] Indoor environmental management in an external preparation room refers to the management of air quality and temperature. Air circulation management aims to optimize air flow within the room and ensure healthy respiratory function for workers. Temperature management can improve worker comfort and inhibit microbial growth. Existing technology typically includes three types of treatment facilities: a dumping station, a cage washer, and a sterilizer. Waste to be treated is first dumped into the dumping station. Any reusable items (such as cages) are then transferred to the cage washer for cleaning before entering the sterilizer for biochemical sterilization.

[0005] Since the length and difficulty of the processing process for different types of waste to be treated in the external preparation room vary, the working state combinations of the three types of facilities, namely the dumping table, cage washing machine and high-temperature sterilizer, are also quite variable. For example, the dumping table will cause disturbances in the indoor air flow when it is opened and closed; the high-temperature sterilizer is a high-temperature facility, which will significantly affect the indoor temperature of the external preparation room when it is put into operation. In the prior art, the external preparation room is usually managed by a central fresh air system that works 24 hours a day, which can complete the tasks of ventilation and temperature control. For example, the Chinese patent document with publication number CN206531199U discloses a central fresh air system, which exchanges the outdoor fresh air with the indoor stale air by setting a first motor and a fresh air inlet, thereby improving the freshness quality of the indoor air; and it also quickly absorbs and releases heat by setting a full heat exchanger, ensuring sufficient heat exchange between the air and maintaining the indoor temperature.

[0006] However, the control strategy for this central fresh air system is relatively simple. When applied to specialized facilities like the external preparation rooms of laboratory animal centers, which have specialized functions and specific needs, it cannot provide targeted energy-saving management and control. Instead, it can only mechanically adjust the overall system output power up or down. To meet laboratory environmental quality regulations, the system operates 24 / 7, resulting in significant energy waste. Furthermore, the system lacks specialized capabilities to address potential biochemical contamination generated during the dumping process in the external preparation room, hindering the cleanliness of the biochemical environment in the external preparation room. Summary of the Invention

[0007] The purpose of the present invention is to provide a clean and energy-saving management system suitable for the external preparation room of an experimental animal center, which can significantly save electricity and energy consumption and optimize the biochemical environment of the external preparation room.

[0008] In order to achieve the above-mentioned purpose, the technical solutions provided by the present invention are as follows: A cleaning and energy-saving management system for an external preparation room in an experimental animal center, wherein the external preparation room is provided with a dumping table, a cage washer, and a high-temperature sterilizer. The system comprises: Fresh air module, including indoor ventilation unit for managing indoor air quality and room temperature, and active cooling unit for cooling the high-temperature sterilizer; The inactivation and cooling unit is connected to the pouring table and the high-temperature sterilizer and is used to draw the normal-temperature contaminated air in the pouring table to the high-temperature sterilizer for heat exchange; The dehumidification and cooling unit is connected to the cage washer and the high-temperature sterilizer to extract the high-humidity air in the cage washer to the high-temperature sterilizer for heat exchange; The control module is used to collect characteristic parameters at the tipping table, cage washing machine and high-temperature sterilizer, perform analysis and calculation, and control the start and stop status of the active cooling unit, inactivation cooling unit and dehumidification cooling unit.

[0009] As a preferred embodiment of the present invention, the indoor ventilation unit includes an indoor air outlet port and an indoor exhaust port, the indoor air outlet port is arranged at a remote location close to the tipping table and the cage washing machine; the indoor exhaust port is arranged at a near location close to the high-temperature sterilizer.

[0010] As a preferred embodiment of the present invention, the control module includes a sensing unit, which includes a first temperature sensor for detecting the ambient temperature at the high-temperature sterilizer, a first trigger sensor arranged at the dumping table, and a second trigger sensor arranged at the cage washing machine.

[0011] The sensing unit includes a first temperature sensor located at the autoclave, a first trigger sensor located at the tilting platform, and a second trigger sensor located at the cage washer. The first temperature sensor can be implemented using conventional hardware such as an infrared temperature sensor, a radiation thermometer, or a thermocouple. It provides real-time feedback on the ambient temperature of the autoclave, which reflects the desired cooling requirements for the autoclave. For example, multiple temperature thresholds can be set to activate different cooling units to cool the autoclave. The more cooling units activated, the better the cooling effect. The first trigger sensor located at the tilting platform and the second trigger sensor located at the cage washer are used to detect the operating status of the tilting platform and the cage washer, respectively. For example, the first and second trigger sensors can be implemented using microswitches that generate a trigger signal when the tilting platform's screen door or the cage washer's lid actuates. Alternatively, they can be implemented using vibration sensors that generate a trigger signal when they detect vibration during operation. Alternatively, they can be implemented using an electrical signal collector that detects electrical signals in the start-up circuit when the two are in electronic on / off or electronic start / stop mode to generate a trigger signal. The trigger signal is transmitted to the central processing unit in the control module, which is responsible for analysis and calculation. After the central processing unit performs calculations and judgments, it generates corresponding control signals and sends them to the inactivation and cooling unit and the dehumidification and cooling unit respectively.

[0012] As a preferred embodiment of the present invention, the inactivation and cooling unit includes a first cooling pipeline that conflicts with the heat exchanger of the high-temperature sterilizer and an exhaust device connected to the first cooling pipeline and installed inside the tipping table.

[0013] The vacuum device is implemented based on the vacuum pump and other equipment in the prior art. Its suction direction is from the inside of the tilting table to the first cooling pipeline. After the normal temperature contaminated air inside the tilting table enters the first cooling pipeline, the air pressure inside the device decreases. In order to maintain the air pressure balance, the indoor air will flow into the inside of the tilting table, that is, the formation of local negative pressure can prevent the normal temperature contaminated air from dissipating to the outside preparation room. Whether the vacuum device is started or not is controlled by the control module. For example, the control module can send a start instruction to it, and attach a delay instruction, so that the vacuum device can maintain continuous suction for a specified time after startup; the first cooling pipeline extends to the high-temperature sterilizer, but is not connected to the high-temperature sterilizer. It conflicts with the heat exchanger in the high-temperature sterilizer and exchanges temperature through direct medium heat conduction, thereby taking away the heat in the high-temperature sterilizer.

[0014] As a preferred embodiment of the present invention, the dehumidification and cooling unit includes a second cooling pipeline that conflicts with the heat exchanger of the high-temperature sterilizer and a water vapor pump connected to the second cooling pipeline and installed in the cage washing machine.

[0015] A water vapor pump is installed inside the cage washer, continuously pumping air into the machine while it's operating. The cage washer's operating mode typically includes a three-dimensional spraying step, creating small droplets that rapidly increase the moisture content of the air inside. Once the water vapor pump completes and maintains the suction state, opening the cage washer's lid effectively prevents humidity increases in the external preparation room. The water vapor pump delivers the highly humid air into a second cooling line, which extends to the autoclave but is disconnected from it. This line, which interferes with the autoclave's heat exchanger, exchanges temperature through direct medium heat conduction. Since highly humid air has a higher specific heat capacity than dry air, it can remove more heat, resulting in better heat dissipation.

[0016] As a preferred embodiment of the present invention, the active cooling unit includes a third cooling pipeline that conflicts with the heat exchanger of the high-temperature sterilizer and an electric valve connected to the third cooling pipeline and installed on the third cooling pipeline.

[0017] The cooling medium in the active cooling unit comes from outdoor fresh air. Since the temperature of outdoor fresh air is always lower than that of the high-temperature sterilizer, based on this temperature difference, it can be directly used to cool the high-temperature sterilizer. When the electric valve on the third cooling pipeline is opened, part of the outdoor fresh air is guided to the heat exchanger of the high-temperature sterilizer to participate in the heat exchange work. The electric valve can also adjust the valve opening size according to the control command, thereby adjusting the outdoor fresh air volume at the heat exchanger of the high-temperature sterilizer through the third cooling pipeline.

[0018] As a preferred embodiment of the present invention, the sensing unit includes a second temperature sensor for detecting the indoor air temperature; the control module includes a central processing unit, which receives temperature information from the first temperature sensor and the second temperature sensor, performs difference mapping, and generates a control instruction group based on the mapping result.

[0019] As a preferred embodiment of the present invention, the sensing unit further includes an ammonia concentration sensor provided in the tipping platform, and the ammonia concentration sensor is used for performing biochemical feedback and early warning on the internal environment of the tipping platform.

[0020] As a preferred embodiment of the present invention, the heat exchanger is connected to an air outlet pipeline of a high-temperature sterilizer, and the air outlet pipeline of the high-temperature sterilizer is used to guide the exhaust gas after heat exchange to the outdoor atmosphere or a sterilization collection and exhaust system.

[0021] Among them, the high-temperature sterilizer outlet duct is connected to the heat exchanger, which is used to guide the exhaust gas in the three cooling ducts directly to the outside or the sterilization collection and exhaust system at the end of the duct. If the tipping table is not working, the exhaust gas in the high-temperature sterilizer outlet duct can be directly guided to be discharged outdoors; if the tipping table is working, the first cooling duct guides the normal temperature contaminated air containing biological bacteria in the tipping table to the heat exchanger to complete the heat exchange, and then the high-temperature sterilizer outlet duct guides it to the sterilization collection and exhaust system to avoid direct discharge of the biological bacteria and residual ammonia-containing substances contained therein that are not completely eliminated to the outside. The sterilization collection and exhaust system can be realized by relying on various inactivation and sterilization devices and ammonia removal devices in the prior art. For example, the final sterilization and ammonia removal can be achieved by sequentially using a high-efficiency filter, a hydrogen peroxide disinfection device and a phosphoric acid absorption device, or by using NaOH solution and NaClO solution to eliminate small molecular pollutants such as ammonia, sulfide, and ozone. In addition, the exhaust selection direction in the above-mentioned high-temperature sterilizer outlet duct can be realized based on the automatic control valve technology in the prior art. For example, it can be achieved by Figure 1 The dual-channel electric switching valve shown selectively controls the exhaust gas in the high-temperature sterilizer outlet duct to be discharged to the outdoor atmosphere or the sterilization collection and exhaust system to meet the processing requirements under specific working conditions.

[0022] As a preferred embodiment of the present invention, the indoor air outlet port includes an air outlet control device, and the air outlet control device is connected to the central processing unit and is used to control the opening or closing state of the indoor air outlet port.

[0023] The indoor air outlet includes an air outlet control device, which is used to control the opening and closing of the indoor air outlet. Its control signal originates from a central processing unit (CPU). The CPU is connected to a first trigger sensor and, based on the trigger signal transmitted by the first trigger sensor, generates an air outlet control instruction to control the opening and closing of the indoor air outlet. Specifically, when the tilting platform is in operation, the first trigger sensor sends an opening trigger signal to the CPU, which in turn sends an air outlet control instruction to the air outlet control device to open the indoor air outlet. When the tilting platform is closed, the first trigger sensor sends a closing trigger signal to the CPU, which in turn sends an air outlet control instruction to close (or delay closing) the indoor air outlet. This ensures that indoor fresh air is replenished only during the operating hours of the tilting platform, saving additional cooling energy during summer when outdoor temperatures are high. Furthermore, in another possible implementation, the indoor air outlet is opened for replenishment when the cage washer is operating. Furthermore, in another possible implementation, operational instructions can be manually input into the CPU, allowing it to adapt to a wider range of operating modes.

[0024] In summary, the present invention has the following beneficial effects: 1. Compared with existing technologies, no new high-energy-consuming devices (such as coolers or heaters) are introduced. Instead, the air paths between various devices are replanned by setting up inactivation cooling units and dehumidification cooling units, and modular diversion adjustments are made to the existing central fresh air system. The system's automatic judgment and operation are achieved through parameter collection, calculation analysis, and control management of the control module.

[0025] 2. The present invention integrates the core cooling and heat removal needs, dehumidification needs and biochemical inactivation, that is, through the inactivation and cooling unit's suction and pipeline guidance at the pouring table, the spatial isolation and transfer inactivation of the pollution source are achieved. Specifically, the suction of the inactivation and cooling unit at the pouring table creates a local negative pressure environment inside the pouring table and near the shielding door, so that the room temperature polluted air carrying microorganisms cannot overflow into the indoor space of the external preparation room, which achieves the spatial isolation of the pollution source; on the other hand, the room temperature polluted air is guided by the pipeline to the high-temperature sterilizer, and while heat exchange is taking place, the protein molecular structure of the microorganisms is destroyed by the high temperature, which greatly reduces the number of active microorganisms in the air discharged to the outside.

[0026] 3. In addition, the dehumidification and cooling unit also isolates the high-humidity air at the cage washer. The local negative pressure environment prevents water vapor from escaping, which helps stabilize the indoor humidity. Furthermore, due to the high specific heat capacity of high-humidity air, it also has a stronger heat absorption effect than normal temperature air. Compared with the simple central fresh air system in the existing technology, this technical solution has specific treatment capabilities for biological contamination sources and water vapor, which can significantly optimize the biochemical environment of the external preparation room. It also reduces the amount of heat radiation from the operating high-temperature sterilizer to the indoor space of the external preparation room, reduces the air exchange power consumption of the fresh air module, and saves electricity resources.

DETAILED DESCRIPTION

[0028] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0029] Throughout this specification, the claims, and the accompanying drawings, the terms "first," "second," and so forth are used to distinguish between different items, not to describe a particular order. Furthermore, the term "comprises" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may include other steps or elements inherent to the process, method, product, or apparatus.

[0030] The fresh air module can be implemented using existing central fresh air systems, which also provide basic air filtration and temperature control functions. It includes an indoor ventilation unit for managing indoor air quality and room temperature, and an active cooling unit for cooling the high-temperature sterilizer. Both the indoor ventilation unit and the active cooling unit draw outdoor fresh air through the same outdoor fresh air inlet duct (the port of which is equipped with an exhaust power source). The indoor ventilation unit performs the traditional central fresh air functions (air filtration and temperature control) for ventilation and room temperature control in the outdoor preparation room, while the active cooling unit connects to the high-temperature sterilizer to selectively provide a cooling source. When the high-temperature sterilizer is turned on and enters operation, a large amount of heat accumulates above the heat exchanger. If this heat cannot be channeled away and eliminated, the indoor air temperature will rise due to heat exchange. Part of the outdoor fresh air guided to the high-temperature sterilizer by the active cooling unit has a large temperature difference with the heat exchanger, so the heat on the heat exchanger can be transferred to the outdoors to achieve the effect of active cooling. The heat exchanger can be implemented based on the multi-layer coil or multi-layer blade heat exchanger device in the existing technology, which is used to extend the passage time of the gaseous heat exchange medium and enhance the heat exchange effect.

[0031] The inactivation and cooling unit is connected to the pouring station and the high-temperature sterilizer, and is used to draw room-temperature contaminated air from the pouring station to the high-temperature sterilizer for heat exchange. The inactivation and cooling unit is connected to the pouring station and the high-temperature sterilizer, and is used to draw room-temperature contaminated air from the pouring station to the high-temperature sterilizer for heat exchange. The pouring station is a facility used to handle disposable waste (such as animal feces, urine pads, food residue, and wastewater). It is usually closed. When waste needs to be handled, staff open the shielded door, exposing the pouring channel, and throw the waste into the pouring channel. When the shielded door is opened, contaminated air in the pouring channel, carrying microorganisms and other biochemical bacteria, is released into the indoor environment. The inactivation and cooling unit consists of an exhaust device and a first cooling pipeline, which draws and pushes the room-temperature contaminated air to the heat exchanger of the high-temperature sterilizer for heat exchange. The vacuum device is implemented based on the vacuum pump and other equipment in the prior art. Its suction direction is from the inside of the tilting table to the first cooling pipeline. After the normal temperature contaminated air inside the tilting table enters the first cooling pipeline, the air pressure inside the device decreases. In order to maintain the air pressure balance, the indoor air will flow into the inside of the tilting table, that is, the formation of local negative pressure can prevent the normal temperature contaminated air from dissipating to the outside preparation room. Whether the vacuum device is started or not is controlled by the control module. For example, the control module can send a start instruction to it, and attach a delay instruction, so that the vacuum device can maintain continuous suction for a specified time after startup; the first cooling pipeline extends to the high-temperature sterilizer, but is not connected to the high-temperature sterilizer. It conflicts with the heat exchanger in the high-temperature sterilizer and exchanges temperature through direct medium heat conduction, thereby taking away the heat in the high-temperature sterilizer.

[0032] The dehumidification and cooling unit is connected to the cage washer and autoclave, pumping high-humidity air from the cage washer to the autoclave for heat exchange. The dehumidification and cooling unit consists of a water vapor pump and a corresponding second cooling pipeline located within the cage washer. Cage washers are facilities that process reusable waste (such as cages) and are typically enclosed. When waste needs to be processed, staff open the lid to expose the cleaning tank, place the waste in the tank, close the lid, and initiate the automatic cleaning process. The cleaning process generates a large amount of water vapor (especially from the spray system). When the lid is opened again, this water vapor escapes into the indoor air, disrupting the indoor humidity balance. Frequently disrupting this humidity balance not only affects staff comfort but also increases the potential for microbial growth. In the present invention, high-humidity air is guided by the dehumidification and cooling unit to the high-temperature sterilizer for heat exchange. If the high-temperature sterilizer is in working state at this time, the heat exchanger can quickly heat the high-humidity air. Moreover, since the high-humidity air in this path has a higher water content, its relative specific heat capacity is larger, and it can absorb more heat, thereby increasing its contribution to the heat dissipation of the high-temperature sterilizer.

[0033] like Figure 2 and Figure 3 As shown, the control module is used to collect characteristic parameters from the tilting table, cage washer, and high-temperature sterilizer, perform analysis and calculations, and control the start and stop states of the active cooling unit, inactivation cooling unit, and dehumidification cooling unit. The control module includes a sensing unit, which includes a first temperature sensor located at the high-temperature sterilizer, a first trigger sensor located at the tilting table, and a second trigger sensor located at the cage washer. The control module also includes a central processing unit (CPU), which receives temperature information from the first and second temperature sensors, performs a difference mapping, and generates a control instruction set based on the mapping results. The control instruction set includes a first instruction for controlling the exhaust device, a second instruction for controlling the water vapor pump, and a third instruction for controlling the electric valve. The first, second, and third instructions are all composed of status indication information and time indication information. The CPU can be implemented using existing CPU, FPGA, and other means.

[0034] Among them, the first temperature sensor collects the characteristic parameters at the high-temperature sterilizer and sends them to the central processing unit. The parameter type is temperature value. The temperature at the high-temperature sterilizer reflects the cooling power consumption required by the high-temperature sterilizer at this time. The central processing unit analyzes the required cooling power consumption according to the preset analysis program; in addition, the central processing unit also obtains the current working status of the tipping table and cage washing machine through the trigger status uploaded by the first trigger sensor and the second trigger sensor. The central processing unit generates a control instruction group based on the temperature parameters of the high-temperature sterilizer and the working parameters of the tipping table and cage washing machine. The control instruction group includes a first instruction for controlling the exhaust device, a second instruction for controlling the water vapor pump and a third instruction for controlling the electric valve; the first instruction, the second instruction and the third instruction are all composed of status indication information and time indication information, wherein the status indication information is used to control the on / off state of the exhaust device, the water vapor pump and the electric valve, and the time indication information is used to control the duration of the on / off state, that is, the delay time.

[0035] It is known that a high-temperature sterilizer generally operates at a fixed rated power, and the total amount of heat generated by the sterilizer remains stable during operation. When the high-temperature sterilizer is in operation, the central processing unit analyzes and determines the trigger status uploaded by the first trigger sensor and the second trigger sensor. If both are in trigger mode (i.e., the tipping table and the cage washer are both in trigger mode at this time), the first instruction and the second instruction generated by the central processing unit both contain "on" and delay time numerical information, and the third instruction is left idle, causing the exhaust device and the water vapor pump to start working, so that the normal temperature contaminated air and the high humidity air are respectively sent to the high-temperature sterilizer through the first cooling pipe and the second cooling pipe for heat exchange, removing some heat and lowering the temperature of the high-temperature sterilizer (if either is in the trigger state, only the corresponding exhaust device or water vapor pump is turned on for air guidance); if both the tipping table and the cage washer are in the non-trigger state, the third instruction contains "on" and delay time numerical information, the first instruction and the second instruction are left idle, causing the electric valve to open, and the active cooling unit to guide outdoor fresh air to the high-temperature sterilizer through the third cooling pipe for heat exchange, removing some heat and lowering the temperature of the high-temperature sterilizer.

[0036] In another embodiment, the indoor ventilation unit includes an indoor air outlet port and an indoor exhaust port, the indoor air outlet port is arranged at a remote location close to the tipping table and the cage washing machine; the indoor exhaust port is arranged at a near location close to the high-temperature sterilizer.

[0037] Specifically, if Figure 1As shown, an external preparation room is provided with two indoor air outlet ports, which are arranged on the side of the tilting table and the side of the cage washer, and the ports are located on the far side. In this embodiment, the indoor air outlet port is suspended from the ceiling to introduce outdoor fresh air into the room from top to bottom. In addition, an indoor exhaust port is also provided, which is arranged near the ground near the high-temperature sterilizer to suck the indoor air of the external preparation room and discharge it to the outside. The indoor air outlet port is arranged near the tilting table and the cage washer. With the help of gas propulsion, the local negative pressure intensity at the tilting table and the cage washer can be enhanced. The indoor exhaust port is arranged near the high-temperature sterilizer to quickly suck out the local hotter air near the high-temperature sterilizer, thereby enhancing the heat dissipation efficiency of the high-temperature sterilizer.

[0038] In another embodiment, Figure 3 As shown, a gas flow meter for counting the gas entering the outer preparation room is provided at the indoor exhaust port, which is connected to the central processing unit. The central processing unit can generate corresponding exhaust control instructions based on the total gas intake reported by the gas flow meter within a certain time period, the internal volume of the outer preparation room and the preset prescribed ventilation times; and the indoor exhaust port is also connected to the central processing unit. The central processing unit can control the opening / closing of the indoor exhaust port based on the generated exhaust control instructions, with the purpose of further saving energy consumption while meeting the indoor ventilation requirements. The central processing unit controls the indoor exhaust port of the indoor ventilation unit based on the preset prescribed ventilation times. In another possible implementation form, the outdoor fresh air can be pre-adjusted in temperature by means of an air-conditioning compressor or other devices in the prior art before being delivered to the indoor air outlet.

[0039] In another embodiment, Figure 3 As shown, the sensing unit includes a second temperature sensor for detecting the indoor air temperature, which is used to detect the indoor temperature information, and calculate the difference between the indoor temperature information and the temperature information at the high-temperature sterilizer, and compare the difference with a preset mapping table in real time to monitor the difference fluctuation. Since the indoor temperature of the external preparation room is not a constant value, it fluctuates according to factors such as whether there is someone working and whether it is in the working period. The high-temperature sterilizer may be accidentally opened due to a fault, or it may be abnormally high temperature during operation, resulting in a sudden change in the indoor temperature and the temperature at the high-temperature sterilizer. If the central processing unit obtains real-time comparison information based on the mapping table, it can directly generate a control instruction group to selectively or completely open the exhaust device, water vapor pump and electric valve to quickly cool the high-temperature sterilizer to avoid the risk of overheating.

[0040] In another embodiment, Figure 3As shown, the sensing unit also includes an ammonia concentration sensor provided in the pouring table, which is used for biochemical feedback and early warning of the internal environment of the pouring table. There is a microbial decay environment inside the pouring table, and the main odor substance in the environment is ammonia. For an untriggered pouring table, it is in a continuously closed state, and there may be a risk of excessive ammonia concentration. The ammonia concentration sensor can upload data to the central processing unit. Based on the preset analysis program in the central processing unit, the first instruction is issued in a timely manner to turn on the exhaust device to drain the interior of the pouring table to reduce the ammonia concentration and prevent ammonia substances from being emitted into the indoor air of the external preparation room.

[0041] The above-mentioned first instruction, second instruction and third instruction all contain time indication information, which is a preset time length, so that the suction action in the tipping table, the water vapor suction action in the cage washing machine or the opening state of the electric valve continues for the preset time length. This control method has simple logic and can ensure continuous and effective suction.
