[0032] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Example 1

[0034] In a preferred embodiment 1 of the present invention, an environmental adjustment system is provided. Specifically, Figure 1 An optional structural diagram of the environmental adjustment system is shown in FIG. Figure 1 As shown, the environmental regulation system includes:

[0035] System ontology; such as Figure 1 As shown in , the system body is located on the partition structure between the outdoor and indoor, such as on the wall. When the use environment is a cold storage, the system body is located on the cold storage body. Figure 1 Taking the cold storage as an example, the system body can be vertically installed on the cold storage body 1, that is, installed above the cold storage body 1, with the lower side connected to the room and the upper side connected to the outside. In addition, it can also be installed on the side of the cold storage, such as the left side of the cold storage, with the left side connected to the outside and the right side connected to the room;

[0036] The air handling device is located in the system body, and divides the system body into a first air duct and a second air duct; wherein the first end of the first air duct is connected to the indoor environment, and the second end of the first air duct is connected to the outdoor environment, and is used to discharge the indoor return air to the outdoor; the first end of the second air duct is connected to the indoor environment, and the second end of the second air duct is connected to the outdoor environment, and is used to bring fresh air into the room; the environmental conditioning system of the present invention uses an air handling device to separate the system body, such as Figure 1As shown, it is divided into a first air duct on the left and a second air duct on the right. The first air duct performs the return air function, and the second air duct performs the fresh air function. The return air function can be used to change the air indoors and improve the fresh air effect. On the other hand, when there is a peculiar smell in the cold storage, the peculiar smell of the air is discharged, which has a purifying effect. For example, if a cold storage has stored seafood, the smell will not dissipate for a long time. If you want to store other goods at this time, the smell will spread. A cold storage that has not been used for a long time will also breed a large number of bacteria and peculiar smell in a closed environment, and it is very troublesome to clean. In view of the above situation, the air handler in the present invention can use the first air duct to discharge the indoor return air to the outside for odor removal or sterilization. On the other hand, fresh air is introduced through the second air duct to circulate the indoor air for ventilation, odor removal and sterilization. At the same time, the use of an air handler to separate the return air channel and the fresh air channel can save costs on the one hand and avoid using other partition structures for air duct separation. On the other hand, it is easy to realize the multi-function of the system, that is, the air handler is divided into multiple sections to perform multiple functions.

[0037] The air handler is divided into multiple sections, including at least a heat exchange section 2, which is used to exchange heat with indoor return air. The indoor return air in the first air duct enters the room through the second air duct after heat exchange in the heat exchange section 2. The heat exchange section 2 is one of the functions of the air handler. Based on the position of the air handler, that is, the position of the heat exchange section 2, the first air duct and the second air duct are used to form a heat exchange air duct in addition to the return air and fresh air functions, that is, the first air duct and the second air duct in the present application are integrated with multiple functions, which expands the function of the system. The use of the air duct can realize the integration of multiple functions without expanding the size of the structure, avoiding excessive system volume and increased cost.

[0038] In the above embodiment, an integrated environment adjustment system capable of adjusting the environment in a cold storage is provided, the system includes an air processor, the system body is divided into a first air duct and a second air duct, the first air duct has a return air function, which is used to discharge the indoor return air to the outside, and the second air duct has a fresh air function, which is used to introduce fresh air into the room. At the same time, the air processor is divided into multiple sections and has multiple functions, including at least a heat exchange section 2, which is used to exchange heat with the indoor return air, and the indoor return air in the first air duct enters the room through the second air duct after heat exchange in the heat exchange section 2. Therefore, in addition to the return air and fresh air functions, the first air duct and the second air duct are also used to form a heat exchange air duct, which cooperates with the air processor so that the system integrates at least the functions of return air discharge, fresh air introduction and temperature adjustment, effectively solving the problems of the internal environment and single function of the cold storage in the prior art, providing a variety of storage environments for the cold storage, suitable for the storage of different goods, enriching the functions of the system, improving the versatility of the cold storage, reducing the system cost, and ensuring a good environment in the cold storage, and improving the storage quality of the goods.

[0039] In a preferred embodiment of the present invention, the air handler further includes: a humidity regulating section 3, which is used to regulate the indoor humidity. The indoor return air in the first air duct enters the room through the second air duct after the humidity is regulated in the humidity regulating section 3. The function of the environmental regulation system in the present invention is further expanded, that is, the humidity of the indoor environment can be regulated by the humidity regulating section 3. The regulation type includes dehumidification and humidification. The humidity regulating section 3 can be set according to the humidity requirements. Therefore, in addition to the return air, fresh air and heat exchange air duct functions, the first air duct and the second air duct also have a humidity regulation function. By integrating the humidity regulation function, the function of the system is further expanded, a combination of multiple functions is realized, and the versatility of the system is improved. It can be used for the storage of different goods, avoiding the problems of single storage environment and single function of cold storage in the prior art, and high cost of cold storage with multiple functions.

[0040] In order to achieve precise control of humidity and heat transfer, such as Figure 1 As shown, the system further includes: a heat exchange air valve 4, located at the air inlet side of the heat exchange section 2, for controlling the heat exchange section 2 and the indoor return air to perform heat exchange; a humidity regulating air valve 5, located at the air inlet side of the humidity regulating section 3, for controlling the humidity regulating section 3 to perform humidity regulation on the indoor return air. By setting the heat exchange air valve 4 and the humidity regulating air valve 5, the opening and closing of the heat exchange section 2 and the humidity regulating section 3 can be accurately controlled to achieve the effect of accurately regulating the indoor environment.

[0041] In another preferred embodiment of the present invention, the system further includes: a first air valve 6, located in the first air duct, used to divide the first air duct into two parts, one of which is connected to the heat exchange section 2, and the other part is connected to the humidity adjustment section 3; a second air valve 7, located in the second air duct, used to divide the second air duct into two parts, one of which is connected to the heat exchange section 2, and the other part is connected to the humidity adjustment section 3; wherein the heat exchange section 2 is located on the side close to the indoor environment, and the humidity adjustment section 3 is located on the side close to the outdoor environment, when the heat exchange section 2 is used to exchange heat with the indoor environment, the first air valve 6 and the second air valve 7 are closed, and when the humidity adjustment section 3 is used to adjust the indoor humidity, the first air valve 6 and the second air valve 7 are opened. The heat exchange section 2 and the humidity adjustment section 3 can be interchanged, and correspondingly, the switching modes of the first air valve 6 and the second air valve 7 are also interchanged. The above-mentioned first air valve 6 and second air valve 7, in cooperation with the heat exchange air valve 4 and the humidity adjustment air valve 5, can further realize the precise control of the opening and closing of the heat exchange section 2 and the humidity adjustment section 3, so as to achieve the effect of accurately regulating the indoor humidity and temperature, and improve the regulation accuracy of the indoor environment and the preservation effect of the cold storage.

[0042] like Figure 1As shown, the system also includes: a return air fan 8, located at the first end of the first air duct, for introducing indoor return air into the first air duct; a return air valve 9, located at the second end of the first air duct, for controlling the indoor return air to be discharged outdoors; a fresh air fan 10, located at the second end of the second air duct, for introducing fresh air into the second air duct; a fresh air valve 11, located at the second end of the second air duct, for controlling the fresh air to enter the second air duct; an environmental detection device 12, connected to the indoor environment, for detecting indoor environmental parameters, wherein the indoor environmental parameters include at least one of the following: indoor temperature, indoor humidity, and indoor gas concentration. The return air fan 8 and the return air valve 9 are used to realize the return air function. The fresh air fan 10 and the fresh air valve 11 are used to realize the fresh air function. An environmental detection device 12 is provided in the cold storage, and different parameters such as humidity, oxygen content, carbon dioxide concentration, air quality, etc. can be set for different goods, different storage conditions, etc., and real-time collection and analysis can be performed to determine that the system performs the corresponding function and accurately control the indoor environment.

[0043] In order to meet the requirements of different environmental conditions and different cargo storage conditions, the present invention provides a highly integrated system that can adjust the environment inside the cold storage. It utilizes the precise coordination of air valves, fans, air handlers and environmental detection systems to simply and efficiently realize the adjustment of cold storage temperature, the discharge of exhaust gas, the introduction of fresh air, the regulation of oxygen concentration and humidity in the cold storage and other indicators. It integrates functions such as fresh air, air treatment, refrigeration and dehumidification, and expands the functions and universality of the environmental adjustment system.

[0044] Example 2

[0045] In a preferred embodiment 2 of the present invention, a method for controlling an environmental regulation system is provided, which is applied to the environmental regulation system in the above embodiment 1. Specifically, Figure 2 An optional flow chart of the method is shown as follows: Figure 2 As shown, the method includes the following steps S202-S206:

[0046] S202: Acquire indoor environment parameters and target environment parameters;

[0047] S204: Determine an operation mode of the environment adjustment system according to the indoor environment parameters and the target environment parameters;

[0048] S206: Controlling the operation of the environmental adjustment system according to the operation mode.

[0049] In the above embodiment, an integrated environment conditioning system capable of regulating the environment in a cold storage is provided, the system includes an air processor, the system body is divided into a first air duct and a second air duct, the first air duct has a return air function, which is used to discharge the indoor return air to the outside, and the second air duct has a fresh air function, which is used to pass the fresh air into the room. At the same time, the air processor is divided into multiple sections and has multiple functions, including at least a heat exchange section, which is used to exchange heat with the indoor return air, and the indoor return air in the first air duct enters the room through the second air duct after heat exchange in the heat exchange section. Therefore, in addition to the return air and fresh air functions, the first air duct and the second air duct are also used to form a heat exchange air duct, which cooperates with the air processor so that the system integrates at least the functions of return air discharge, fresh air introduction and temperature regulation, effectively solving the problems of the internal environment and single function of the cold storage in the prior art, providing a variety of storage environments for the cold storage, suitable for the storage of different goods, enriching the functions of the system, improving the versatility of the cold storage, reducing the system cost, and ensuring a good environment in the cold storage, and improving the storage quality of the goods.

[0050] As mentioned above, the system of Example 1 of the present invention can realize the regulation of cold storage temperature, exhaust gas discharge, introduction of fresh air, regulation of oxygen concentration and humidity in the storage, and integrates functions such as fresh air, air treatment, refrigeration, and dehumidification. Therefore, the operation mode of this system at least includes: temperature control mode, dehumidification mode, fresh air mode, and deodorization mode; indoor environmental parameters include at least one of the following: indoor temperature, indoor humidity, first indoor gas concentration, and second indoor gas concentration; target environmental parameters include at least one of the following: target indoor temperature, target indoor humidity, target first indoor gas concentration, and target second indoor gas concentration; the operation mode of the environmental adjustment system is determined according to the indoor environmental parameters and the target environmental parameters, including: when the indoor temperature is greater than the target indoor temperature, the operation mode is determined to be the temperature control mode; when the indoor humidity is greater than the target indoor humidity, the operation mode is determined to be the dehumidification mode; when the first indoor gas concentration is less than the target first indoor gas concentration, the operation mode is determined to be the fresh air mode; when the second indoor gas concentration is greater than or equal to the target second indoor gas concentration, the operation mode is determined to be the deodorization mode. The first indoor gas concentration can adopt the oxygen concentration, that is, the fresh air mode is adopted when the oxygen concentration is small. The second indoor gas concentration can be a gas used to indicate air odor. For example, if the cold storage has not been used for a long time and has produced odor, when the second indoor gas concentration is greater than or equal to the target second indoor gas concentration, the odor removal mode is adopted to discharge the odor in the storage. When temperature or humidity control is required, the temperature control mode or dehumidification mode is adopted to perform targeted control and accurately control the indoor environment.

[0051] After determining the operating mode, the operation of the environmental conditioning system is controlled according to the operating mode, including: when the operating mode is the temperature control mode, controlling the return air fan and the heat exchange air valve to open; when the operating mode is the dehumidification mode, controlling the return air fan, the first air valve, the second air valve and the humidity adjustment air valve to open; when the operating mode is the fresh air mode, controlling the fresh air fan, the fresh air valve and the second air valve to open; when the operating mode is the odor removal mode, controlling the return air fan, the first air valve and the return air valve to open.

In this mode, the air in the cold storage can be heat exchanged through the heat exchange section to achieve cooling and cooling.

[0053] Figure 4 An optional schematic diagram showing the system operation mode corresponding to the dehumidification mode. For example, when plant seeds need to be stored and the temperature is suitable, but the humidity in the warehouse is too high, the system will adopt the dehumidification mode, the return air fan will work, and the first air valve, the second air valve and the humidity adjustment air valve will be opened. At this time, the system will circulate the cold air in the humidity adjustment section of the air handler to dehumidify without any loss of cooling capacity.

When fresh goods are stored in the cold storage, fresh air needs to be introduced under certain circumstances. At this time, the system turns on the fresh air mode, the fresh air fan works, the fresh air valve and the second air valve are opened, and the other air valves are closed. In this mode, fresh air can be introduced from the external environment.

At this time, the system adopts the clean odor mode. At this time, the return air fan works, the first air valve and the return air valve are opened, and the other air valves are closed. At this time, the odor in the storage can be discharged, and the refrigeration mode is turned on when the conditions are met.

[0056] Through the above method, the control system can be used to simply and efficiently realize functions such as fresh air, air treatment, refrigeration, and odor purification. Not only that, it has a high degree of integration and high adaptability, and users can meet various usage needs according to different warehouse environments.
