The refrigerant refrigeration system is equipped with a evaporative air cooler at the terminal, while the water system is equipped with a combined air conditioning unit at the terminal, respectively meeting the indoor temperature and cleanliness requirements. However, during system operation, the use of these two systems presents challenges due to complex linkage control, the risk of condensation in the air supplied by the combined air conditioning unit, and the technical problem that the combined air conditioning unit cannot start due to excessively low return air temperature in low-temperature processing rooms.

[0043] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0044] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0045] Figure 1 This is a schematic diagram of an optional indoor cooling system according to an embodiment of this application, such as... Figure 1 An indoor cooling system is shown, comprising: a refrigerant unit, a fan cooler, and an air conditioning unit;

[0046] The refrigerant unit is connected to the air cooler and air conditioning unit to transfer refrigerant to the air cooler and / or air conditioning unit for cooling.

[0047] Specifically, a refrigerant chiller is a unit of equipment used to achieve heat exchange by circulating refrigerant. Furthermore, in this embodiment, the refrigerant chiller is connected to a fan cooler and an air conditioning unit to provide cooling.

[0048] A refrigerant chiller unit may include components such as a compressor, condenser, evaporator, and expansion valve, forming a refrigeration cycle. The compressor compresses the low-pressure refrigerant into a high-pressure gas, which liquefies after cooling in the condenser. It then reduces pressure and temperature through the expansion valve and finally absorbs heat and evaporates in the evaporator, completing the refrigeration cycle. Refrigerant solution circulation: The refrigerant solution is pumped through the evaporator, absorbing the cooling capacity of the refrigerant and lowering its temperature. Optionally, a cooling tower can be included, connected to the refrigerant chiller unit via a water-cooling system. The condenser of the refrigerant chiller unit is typically connected to the water-cooling system, and the water in the system is connected to the cooling tower through pipes, forming a closed-loop system. The water in the cooling tower is pumped through the condenser of the refrigerant chiller unit, absorbing heat and increasing in temperature. The heated water then undergoes an evaporative cooling process in the cooling tower to lower its temperature before circulating back to the condenser, thus achieving the purpose of cooling the condenser of the refrigerant chiller unit.

[0049] A refrigerant chiller unit, connected to an air cooler, delivers a low-temperature refrigerant solution to the air cooler. Air is then blown through the coils containing the low-temperature refrigerant within the air cooler, where the refrigerant solution absorbs heat from the air, thus cooling it. Furthermore, the indoor temperature can be precisely controlled by adjusting the flow rate and temperature of the refrigerant solution.

[0050] In this embodiment, the refrigerant unit can be connected to both the evaporative cooler and the air conditioning unit to achieve independent cooling through each unit. Alternatively, the refrigerant unit can be connected in series with both the evaporative cooler and the air conditioning unit to achieve simultaneous cooling through both units. Furthermore, the refrigerant unit, evaporative cooler, and air conditioning unit can be connected in other ways, which are not limited here.

[0051] Refrigerant units, when connected to air conditioning units, can perform cooling by transferring refrigerant solution to the air conditioning units in a manner similar to that of evaporative coolers.

[0052] In this embodiment, a refrigerant chiller unit is used to transfer refrigerant to a evaporative cooler and / or an air conditioning unit for cooling. The indoor cooling system includes a refrigerant chiller unit, an evaporative cooler unit, and an air conditioning unit. The refrigerant chiller unit is connected to both the evaporative cooler unit and the air conditioning unit to transfer refrigerant to them for cooling. This allows for cooling using refrigerant from a single refrigerant chiller unit. The refrigerant chiller unit is simultaneously connected to both the evaporative cooler unit and the air conditioning unit, meeting the requirements for indoor temperature regulation and cleanliness. Since a water system is not required, condensation is effectively avoided during air conditioning unit operation. Furthermore, the use of the same refrigerant for both the evaporative cooler unit and the air conditioning unit simplifies the linkage control, thus solving the problems of complex linkage control between multiple systems, condensation risks in combined air conditioning units, and inability to start in related technologies.

[0053] As an optional implementation, as described above in the indoor refrigeration system, the refrigerant unit is an ethylene glycol unit, the refrigerant is an ethylene glycol solution, and the air conditioning unit is a combined air conditioning unit. That is, in this embodiment, by using an ethylene glycol solution as the refrigerant, the refrigerant unit is a unit used for cold circulation via the ethylene glycol solution. The ethylene glycol solution circulates within the indoor refrigeration system to achieve the purpose of indoor cooling. Because ethylene glycol has a low freezing point, this system can operate normally even in very cold environments, preventing the cooling system from freezing in winter. Furthermore, ethylene glycol has a wide operating temperature range; that is, the ethylene glycol solution can remain liquid within a wide temperature range, allowing it to adapt to various application requirements. Moreover, ethylene glycol has good thermal conductivity, effectively transferring heat and rapidly achieving heat transfer, thereby improving the efficiency of the indoor refrigeration system in this embodiment. Simultaneously, ethylene glycol is chemically stable over a wide temperature range, not easily decomposed or deteriorated, allowing it to maintain its performance over long-term use, effectively reducing maintenance costs. In this embodiment, a combined air conditioning unit is used as the air conditioning unit, which can remove dust particles in the air through primary and secondary filters, and can adjust the air humidity in the environment and introduce fresh air to improve indoor air quality as needed and according to the preset target humidity through humidifiers or dehumidifiers.

[0054] like Figure 1As shown, as an optional implementation, the aforementioned indoor refrigeration system further includes: a first valve, a second valve, and a third valve; the first valve is located between the refrigerant outlet of the refrigerant unit and the refrigerant inlet of the air cooler; the second valve is located between the refrigerant outlet of the air cooler and the refrigerant inlet of the air conditioning unit; the third valve is located between the refrigerant outlet of the refrigerant unit and the refrigerant inlet of the air conditioning unit; the refrigerant outlet of the air conditioning unit is connected to the refrigerant return end of the refrigerant unit.

[0055] In other words, when cooling is required through both the evaporative cooler and the air conditioning unit, opening the first and second valves allows the refrigerant flowing from the refrigerant compressor unit to pass sequentially through both the evaporative cooler and the air conditioning unit. This achieves controlled flow of the refrigerant from the compressor unit to both units, meaning that after being used by the evaporative cooler, the refrigerant in the compressor unit can be further utilized by the air conditioning unit, thus achieving the goal of tiered utilization of the refrigerant's cooling capacity. For example, when the compressor unit is an ethylene glycol compressor unit and the refrigerant is an ethylene glycol solution, the piping between the evaporative cooler and the combined air conditioning unit is connected in series. The ethylene glycol solution passes sequentially through the evaporative cooler and the combined air conditioning unit (the default outlet water temperature setting for the ethylene glycol compressor unit is -2℃), achieving tiered utilization of cooling capacity.

[0056] When only cooling is required from the air conditioning unit, the first and second valves can be closed, and only the third valve can be opened. This allows the refrigerant flowing from the refrigerant outlet of the refrigerant compressor to directly enter the air conditioning unit, thus achieving the goal of cooling solely through that unit. For example, assuming the refrigerant compressor is an ethylene glycol unit and the refrigerant is ethylene glycol solution, by closing the first and second valves and opening only the third valve, the ethylene glycol solution cannot enter the evaporative cooler through the first valve; it can only enter the air conditioning unit through the third valve, thus allowing cooling solely through that unit.

[0057] The system in this embodiment provides a method that can cool using both a evaporative cooler and an air conditioning unit, as well as a method that cools using only an air conditioning unit, which can effectively expand the application scenarios of this system.

[0058] As an optional implementation, the indoor refrigeration system described above further includes: an energy storage component for storing cold, a fourth valve, and a fifth valve; the fourth valve is located between the refrigerant outlet of the refrigerant unit and the refrigerant inlet of the energy storage component; the fifth valve is located between the refrigerant outlet of the energy storage component and the refrigerant inlet of the refrigerant unit.

[0059] In this embodiment, the energy storage component is a device for storing cold energy. Specifically, the energy storage component can utilize off-peak electricity or renewable energy sources to make ice or store cold energy, so that this stored cold energy can be used during the day or peak hours to meet air conditioning or cooling needs. The cold storage component can effectively reduce the peak-valley difference in the power grid, improve energy utilization efficiency, and reduce operating costs. Optionally, the energy storage component in this embodiment can be one or more of the following combinations:

[0060] 1. Ice storage system: This can further include: a static ice coil system, a dynamic ice system, and an ice crystal system. The static ice coil system is used to: install ice coils inside the storage tank, where low-temperature water freezes into ice within the coils; the dynamic ice system is used to: directly produce ice within the storage tank, storing the ice mixed with water; the ice crystal system is used to: prepare ice crystals within the storage tank, releasing cooling energy through the dissolution of the ice crystals.

[0061] 2. Water-based cold storage system: This may further include a cold water storage system and a temperature difference cold storage system. The cold water storage system is used to produce low-temperature water during off-peak hours at night and store it in a cold storage tank; the temperature difference cold storage system is used to store cold energy by utilizing the temperature difference between high and low temperature water.

[0062] 3. Phase Change Material (PCM) Cold Storage System: This system uses phase change materials (such as brine solutions, paraffin, etc.) as energy storage media to store and release cold energy during the phase change process.

[0063] In this embodiment, the energy storage component is connected to the refrigerant unit via a fourth valve and a fifth valve. The fourth valve is located between the refrigerant outlet of the refrigerant unit and the refrigerant inlet of the energy storage component, used to input refrigerant from the refrigerant unit into the energy storage component. The fifth valve is located between the refrigerant outlet of the energy storage component and the refrigerant inlet of the refrigerant unit, used to return the refrigerant used for cold storage in the energy storage component to the refrigerant component. Under normal circumstances, when it is determined that the current electricity period is off-peak and there is no need for cooling grading or any cooling from the air conditioning unit, refrigerant from the refrigerant unit is transferred to the energy storage component for cold storage. The cold storage operation can continue until the cold storage in the energy storage component reaches its maximum value, at which point all devices in this embodiment are shut down, and the system stops operating.

[0064] As an optional implementation, the aforementioned indoor refrigeration system further includes a sixth valve and a seventh valve. The sixth valve is located between the refrigerant outlet of the refrigerant unit and the refrigerant inlet of the air refrigeration system, wherein the air refrigeration system includes a evaporative cooler and an air conditioning unit. The seventh valve is located between the refrigerant outlet of the air refrigeration system and the refrigerant inlet of the refrigerant unit. In other words, in this embodiment, the evaporative cooler and the air conditioning unit can be considered as a whole as an air refrigeration system. Furthermore, the air refrigeration system is connected to the aforementioned refrigerant unit via the sixth and seventh valves. The sixth valve is located between the refrigerant outlet of the refrigerant unit and the refrigerant inlet of the air refrigeration system, and the seventh valve is located between the refrigerant outlet of the air refrigeration system and the refrigerant inlet of the refrigerant unit. Therefore, by controlling the sixth and seventh valves to close, the refrigerant from the refrigerant unit can be prevented from entering the air refrigeration system, and the refrigeration through the air refrigeration system can be stopped.

[0065] As an optional implementation, the aforementioned indoor cooling system further includes: a solution pump for controlling the flow rate of refrigerant in the air cooler and / or air conditioning unit; the solution pump is provided at the refrigerant outlet or refrigerant inlet of the refrigerant unit. Specifically, since the solution pump is used to control the flow rate of refrigerant in the air cooler and / or air conditioning unit, the solution pump can be located between the refrigerant outlet of the refrigerant unit and the refrigerant inlet of the air cooling system, or between the refrigerant inlet of the refrigerant unit and the refrigerant outlet of the air cooling system. Furthermore, when the target environment cooled by the air cooler and / or air conditioning unit is too cold, the flow rate of refrigerant in the air cooler and / or air conditioning unit can be reduced by controlling the solution pump to decrease the cooling method and increase the temperature of the target environment; conversely, when the target environment cooled by the air cooler and / or air conditioning unit is too hot, the flow rate of refrigerant in the air cooler and / or air conditioning unit can be increased by controlling the solution pump to increase the cooling method and decrease the temperature of the target environment. The system in this embodiment uses a solution pump to control the flow rate of refrigerant in the evaporative cooler and / or air conditioning unit, thereby achieving the purpose of adjusting the cooling efficiency of the evaporative cooler and / or air conditioning unit.

[0066] According to one aspect of the embodiments of this application, a control method for an indoor cooling system is provided. Optionally, in this embodiment, the control method for the indoor cooling system can be applied to, for example... Figure 2 The hardware environment shown consists of terminal 1402 and server 1404. For example... Figure 2As shown, server 1404 is connected to terminal 1402 via a network and can be used to provide services (such as game services, application services, etc.) to the terminal or clients installed on the terminal. A database can be set up on the server or independently of the server to provide data storage services for server 1404.

[0067] The aforementioned network may include, but is not limited to, at least one of the following: wired network, wireless network. The aforementioned wired network may include, but is not limited to, at least one of the following: wide area network, metropolitan area network, local area network. The aforementioned wireless network may include, but is not limited to, at least one of the following: Wi-Fi (Wireless Fidelity), Bluetooth. The terminal is not limited to PC, mobile phone, tablet computer, etc.

[0068] The control method for the indoor cooling system in this application embodiment can be executed by a server, a terminal, or both. Alternatively, the control method can be executed by a client installed on the terminal.

[0069] Taking the control method of the indoor cooling system in this embodiment executed by a terminal as an example, the control method of the indoor cooling system provided in this application embodiment includes the following steps:

[0070] Step 101: If it is determined that the current period is a peak power period and there is a demand for combined cooling, the refrigerant in the refrigerant unit is transferred to the air cooler and air conditioning unit for combined cooling through the air cooler and air conditioning unit.

[0071] Specifically, by determining the current time and comparing it with preset peak and off-peak time intervals, it can be determined whether it is a peak or off-peak period. The peak period is the time corresponding to the peak electricity consumption period, and the off-peak period is the time corresponding to the low electricity consumption period. Since the electricity price during the peak period is higher than that during the off-peak period, the electricity during the peak period is only used for cooling.

[0072] In this embodiment, refrigerant from the refrigerant chiller is transferred to the evaporative cooler and air conditioning unit only when it is determined that the current period is a peak electricity consumption period and there is a combined cooling demand. The combined cooling demand means that the evaporative cooler and air conditioning unit need to work together to provide cooling. In other words, the combined cooling demand needs to meet both indoor temperature and indoor cleanliness requirements.

[0073] In this embodiment, refrigerant from the refrigerant chiller is transferred to the evaporative air cooler and the air conditioning unit for combined cooling. This allows for cooling using refrigerant from the same chiller chiller. The chiller chiller is simultaneously paired with both the evaporative air cooler and the air conditioning unit, meeting indoor temperature control and cleanliness requirements. Since a water system is not required, condensation is effectively avoided during air conditioning unit operation. Furthermore, the use of the same refrigerant for both the evaporative air cooler and the air conditioning unit simplifies the linkage control, thus solving the problems of complex linkage control between multiple systems, condensation risk in combined air conditioning units, and inability to start in related technologies.

[0074] As an optional implementation, the control method described above can be implemented by the following steps to transfer the refrigerant from the refrigerant unit to the air cooler and air conditioning unit in step 101: controlling the refrigerant unit to sequentially pass through the air cooler and air conditioning unit, so as to utilize the refrigerant in the refrigerant unit in a stepped manner. When for Figure 1 When controlling the indoor refrigeration system shown, if both the evaporative cooler and the air conditioning unit are needed for cooling, the first and second valves can be opened to control the refrigerant unit to pass sequentially through the evaporative cooler and the air conditioning unit. In this case, the refrigerant flowing out of the refrigerant unit can pass sequentially through the evaporative cooler and the air conditioning unit, thus achieving the goal of controlling the refrigerant unit to pass sequentially through the evaporative cooler and the air conditioning unit. In other words, after being used by the evaporative cooler, the refrigerant in the refrigerant unit can be further used by the air conditioning unit, thereby achieving the purpose of tiered utilization of the cooling capacity of the refrigerant in the refrigerant unit. For example, when the refrigerant unit is an ethylene glycol unit and the refrigerant is an ethylene glycol solution, the piping between the evaporative cooler and the combined air conditioning unit is connected in series, and the ethylene glycol solution passes sequentially through the evaporative cooler and the combined air conditioning unit (the default setpoint for the outlet water temperature of the ethylene glycol unit is -2℃), achieving tiered utilization of the cooling capacity.

[0075] As an optional implementation, the control method described above further includes the following steps:

[0076] Step 201: Given that the current temperature of the target environment is within the target temperature range, maintain the current operating frequency of the solution pump unchanged and continue combined cooling. The target environment is the cooling environment supplied by the evaporative cooler and air conditioning unit. The solution pump controls the refrigerant flow rate in the evaporative cooler and air conditioning unit. Optionally, a temperature sensor can be installed in the target environment to obtain the current temperature T. The current temperature can then be compared with the target temperature range to determine the relationship between the two. The target temperature range can be the indoor target temperature T of the target environment.目 The temperature range after fluctuating up and down according to a temperature deviation value △T (for example, △T defaults to 1℃ and is adjustable within the range of 0 to 2℃), i.e., [T 目 -△T,T 目 +△T]. If the indoor target temperature T 目 -△T≤Current TemperatureT≤Indoor Target TemperatureT 目 +△T, the operating status of each component of the system remains unchanged, the current operating frequency of the solution pump remains unchanged, and the combined cooling continues.

[0077] Furthermore, if the current cooling method is not a combined cooling system, it is sufficient to maintain the current cooling method unchanged. For example, if the current cooling method involves combined cooling via radiative heat exchange from energy storage components and convective heat exchange from air coolers and air conditioning units, then the cooling method should remain the same. If the current cooling method involves combined cooling via radiative heat exchange from energy storage components and convective heat exchange from air conditioning units, then the cooling method should remain the same.

[0078] Step 202: If the current temperature of the target environment is determined to be higher than the upper limit of the target temperature range, the cooling efficiency of the evaporative cooler and air conditioning unit is increased by controlling the current operating frequency of the solution pump. Specifically, if the current temperature of the target environment is determined to be higher than the upper limit of the target temperature range, it indicates that the current temperature of the target environment is too high, and the cooling efficiency of the evaporative cooler and air conditioning unit is too low, requiring an increase in cooling efficiency. That is, if the current temperature T > indoor target temperature Tm + ΔT (i.e., the upper limit of the target temperature range), the current operating frequency of the solution pump can be increased to accelerate the flow of refrigerant into the evaporative cooler and air conditioning unit, thereby increasing the cooling efficiency of the evaporative cooler and air conditioning unit. Furthermore, the cooling operating frequency of the solution pump can be gradually increased while observing whether the latest temperature of the target environment is within the target temperature range. If it is not lower than the upper limit of the target temperature range, the current operating frequency of the solution pump is continuously increased until it reaches its maximum.

[0079] Step 203: If the current temperature of the target environment is determined to be lower than the lower limit of the target temperature range, the cooling efficiency of the evaporative cooler and air conditioning unit is reduced by decreasing the current operating frequency of the solution pump. If the latest current temperature of the target environment is still lower than the lower limit of the target temperature range after the current operating frequency of the solution pump has been reduced for a preset time, the operation of the evaporative cooler is turned off. Specifically, if the current temperature of the target environment is determined to be lower than the lower limit of the target temperature range, it indicates that the current temperature of the target environment is too low, and the cooling efficiency of the evaporative cooler and air conditioning unit is too high, requiring a reduction in cooling efficiency. In other words, if the current temperature T < indoor target temperature Tm - ΔT (i.e., the lower limit of the target temperature range), the rate at which refrigerant flows into the evaporative cooler and air conditioning unit can be reduced by decreasing the current operating frequency of the solution pump, thereby reducing the cooling efficiency of the evaporative cooler and air conditioning unit. Furthermore, the duration for which the cooling efficiency of the evaporative cooler and air conditioning unit is reduced does not exceed a preset duration t1. The preset duration t1 can be pre-set and represents the maximum duration for which the evaporative cooler and air conditioning unit operate together when the real-time ambient temperature is below the lower limit of the target temperature range, provided that the evaporative cooler and air conditioning unit are operating in conjunction. Furthermore, if the duration for which the current operating frequency of the solution pump is reduced exceeds the preset duration t1, and the latest current temperature of the target environment is still below the lower limit of the target temperature range, then if the latest current temperature T... 新 The indoor target temperature Ttarget - ΔT (ΔT defaults to 1℃, adjustable from 0 to 2℃) can be controlled by turning it off. Figure 1 The first and second valves shown can be used to shut down the operation of the air cooler by opening only the third valve, so that the terminal is cooled only by the air conditioning unit. Alternatively, if the energy storage component can still radiate heat exchange, the air conditioning unit and the energy storage component can be used together for cooling.

[0080] As an optional implementation, the control method described above further includes the following steps: when it is determined that the current period is a low-voltage electricity period and there is no cooling demand, the refrigerant in the refrigerant unit is transferred to the energy storage component for cold storage until the cold storage of the energy storage component reaches its maximum value, wherein the cooling demand is the demand for cooling through at least one of the air cooler and the air conditioning unit.

[0081] In this embodiment, the energy storage component is a device for storing cold energy. Specifically, the energy storage component can be a technology that utilizes off-peak electricity or renewable energy to make ice or store cold energy, so that the stored cold energy can be used during the day or peak hours to meet air conditioning or cooling needs. The cold energy storage component can effectively reduce the peak-valley difference in the power grid, improve energy utilization efficiency, and reduce operating costs. Optionally, the energy storage component in this embodiment can be one or more combinations of the following: Ice storage system: may further include: a static ice coil system, a dynamic ice system, and an ice crystal system. The static ice coil system is used to: have ice coils inside the cold storage tank, where low-temperature water freezes into ice; the dynamic ice system is used to: directly make ice inside the cold storage tank, storing the ice mixed with water; the ice crystal system is used to: prepare ice crystals inside the cold storage tank, releasing cold energy through the dissolution of the ice crystals. Water storage system: may further include: a cold water storage system and a temperature difference storage system. The cold water storage system is used to produce low-temperature water during off-peak hours at night and store it in a cold storage tank. The temperature difference cold storage system is used to store cold energy by utilizing the temperature difference between high and low temperature water. The phase change material (PCM) cold storage system uses phase change materials (such as brine solutions, paraffin, etc.) as energy storage media to store and release cold energy during the phase change process.

[0082] Due to such Figure 1 As shown: The fourth valve is located between the refrigerant outlet of the refrigerant unit and the refrigerant inlet of the energy storage assembly, used to input refrigerant from the refrigerant unit into the energy storage assembly; the fifth valve is located between the refrigerant outlet of the energy storage assembly and the refrigerant inlet of the refrigerant unit, used to return the refrigerant that has been used for cold storage in the energy storage assembly to the refrigerant assembly. Therefore, when it is determined that there is no need for cooling through at least one of the air cooler and air conditioning unit, it can be controlled by... Figure 1 The fourth and fifth valves are opened, while the sixth and seventh valves are closed, allowing the energy storage component to connect to the refrigerant unit via the open fourth and fifth valves. Furthermore, in this embodiment, refrigerant from the refrigerant unit is only transferred to the energy storage component for cold storage when it is determined that the current electricity period is off-peak and there is no need for cooling grading or any of the air conditioning units to provide cooling (i.e., there is no cooling demand). This cold storage operation can continue until the energy storage component reaches its maximum capacity, at which point all devices in this embodiment are shut down, causing the system to stop operating.

[0083] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to this application. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to this application.

[0084] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM (Read-Only Memory) / RAM (Random Access Memory), magnetic disk, optical disk), and includes several instructions to cause a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods described in the various embodiments of this application.

[0085] like Figure 3 As shown, an application example of the control method for the indoor cooling system in any of the foregoing embodiments is provided:

[0086] The system monitors whether there are any usable devices in the cryogenic workshop refrigeration system (i.e., the indoor refrigeration system used in the cryogenic workshop) (e.g., air coolers, combined air conditioning units (i.e., one of the optional air conditioning units), glycol units (i.e., one of the optional refrigerant units), etc.). If none are found, the system issues a fault alarm. If all components of the cryogenic workshop refrigeration system are in a usable state, the cryogenic workshop refrigeration system is started up and put into operation.

[0087] System startup and operation:

[0088] Cold storage mode: During off-peak electricity hours, the ethylene glycol unit and the ethylene glycol solution pump (i.e., the solution pump used to transfer the ethylene glycol solution) are started and running. The sixth and seventh valves are closed, and the fourth and fifth valves are opened. The ethylene glycol solution circulates and exchanges heat in the energy storage component, and the energy storage component stores cold until the energy storage component reaches its maximum value. Then, all equipment is shut down and the system stops running.

[0089] Combined cooling mode: During peak electricity periods, the ethylene glycol unit and ethylene glycol solution pump start up and run, the third, fourth and fifth valves are closed, and the first, second, sixth and seventh valves are opened. The energy storage component provides combined cooling through radiative heat exchange and convective heat exchange with the air cooler and the combined air conditioning unit. The pipes between the air cooler and the combined air conditioning unit are connected in series, and the ethylene glycol solution passes through the air cooler and the combined air conditioning unit in sequence (the default set value of the ethylene glycol unit outlet water temperature is -2℃), realizing the cascade utilization of cooling capacity.

[0090] Monitor the current indoor temperature; if the target indoor temperature T 目 -△T≤Current TemperatureT≤Indoor Target TemperatureT 目 +△T (△T defaults to 1℃ and can be adjusted from 0 to 2℃) keeps the operating status of each component of the system unchanged.

[0091] If the current temperature T > the target indoor temperature T 目 +△T, the operating frequency of the ethylene glycol solution pump increases until it reaches its maximum.

[0092] If the current temperature T < the target indoor temperature T 目 -△T, the operating frequency of the ethylene glycol solution pump decreases for a duration of t1, if the real-time indoor temperature T < the target indoor temperature T 目 -△T, close the first and second valves, open the third valve, shut off the operation of the air cooler, and the terminal is cooled by the combined air conditioning unit and energy storage components.

[0093] According to another aspect of the embodiments of this application, a control device for an indoor cooling system for implementing the control method of the above-described indoor cooling system is also provided. The device may include:

[0094] According to another aspect of the embodiments of this application, a control device for an indoor cooling system is also provided, comprising:

[0095] The control module is used to transfer refrigerant from the refrigerant chiller to the air cooler and air conditioning unit when it is determined that the current period is a peak power period and there is a demand for combined cooling, so as to provide combined cooling through the air cooler and air conditioning unit.

[0096] It should be noted that the control module in this embodiment can be used to execute step 101 above.

[0097] The aforementioned modules transfer refrigerant from the refrigerant chiller to the evaporative cooler and air conditioning unit, enabling combined cooling through these two systems. This allows for cooling using refrigerant from the same chiller unit. The chiller unit, coupled with both evaporative coolers and air conditioning units, can meet indoor temperature control and cleanliness requirements. Since a water system is unnecessary, condensation is effectively avoided during air conditioning unit operation. Furthermore, the use of the same refrigerant for both the chiller and air conditioning unit simplifies control and resolves issues such as complex inter-system control, condensation risks in combined air conditioning units, and inability to start, present in related technologies.

[0098] As an optional embodiment, the control device described above, which transfers refrigerant from the refrigerant unit to the air cooler and air conditioning unit, includes:

[0100] As an optional implementation, the control device described above further includes an adjustment module, which is configured to:

[0101] If the current temperature of the target environment is determined to be within the target temperature range, the current operating frequency of the solution pump is kept constant and combined cooling continues. The target environment is the cooling environment of the air cooler and air conditioning unit. The solution pump is used to control the flow rate of refrigerant in the air cooler and air conditioning unit.

[0102] When the current temperature of the target environment is determined to be higher than the upper limit of the target temperature range, the cooling efficiency of the air cooler and air conditioning unit is increased by controlling the current operating frequency of the solution pump.

[0103] If the current temperature of the target environment is determined to be lower than the lower limit of the target temperature range, the cooling efficiency of the evaporative cooler and air conditioning unit is reduced by controlling the current operating frequency of the solution pump. If the latest current temperature of the target environment is still lower than the lower limit of the target temperature range after the current operating frequency of the solution pump has been reduced for a period of time exceeding the preset time, the operation of the evaporative cooler is turned off.

[0104] As an optional implementation, the control device described above further includes: a cold storage module;

[0105] The cold storage module is used to transfer refrigerant from the refrigerant unit to the energy storage component when it is determined that the current electricity period is off-peak and there is no cooling demand, so that the cold storage component can store cold energy until the cold storage component reaches its maximum value. The cooling demand is the demand for cooling through at least one of the air cooler and the air conditioning unit.
