[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, when describing the pipeline, the "connected" and "connection" used in the present invention have the meaning of conduction. The specific meaning needs to be understood in conjunction with the context.

[0037] In the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0038] As described in the background technology, with the continuous development of daily household appliance technology, more and more household appliances have entered people's daily life and work. At the same time, due to the improvement of scientific and technological levels in real life, people also have corresponding higher demands for the intelligence of household appliances. For this reason, household appliances should also be optimized and improved accordingly.

[0039] Take air conditioners as an example. Currently, air conditioners can only work for cooling or heating. There are office parks and office buildings with a long service life. Office parks and office buildings also have air conditioning systems. However, due to long service life, the fire protection systems of most buildings have been paralyzed. When a fire occurs, the fire is not discovered in time, and the personnel do not respond in time after the fire. After the fire, the internal fire situation cannot be accurately judged, and the source of the fire cannot be accurately traced afterwards. The air conditioning system can provide water to extinguish the fire, but how to use the water of the air conditioning system to extinguish the fire is a problem that needs to be solved at present.

[0040] In order to solve this technical problem, it is necessary to propose a system that links the chiller room with the fire protection. The system, through linkage control, can solve the problems of untimely fire detection, untimely response and inaccurate judgment of the internal fire situation, and can also extinguish the fire.

[0041] Based on this, the present application provides a system for linking a chiller room with fire protection. Figure 1 As shown, the system 1000 for linking a chiller room with a fire fighting system includes: a chiller room system 100 , including: a chiller system 10 , a fan coil unit 20 and a detection system 30 .

[0042] The fan coil unit 20 is connected to the cold water system 10, and is used to perform air heat exchange in the area where it is located through the water flow transmitted by the cold water system 10; the detection system 30 is used to obtain the temperature of the area and obtain temperature data.

[0043] The system 1000 for linking a chiller room with a fire fighting system further comprises: an intelligent control system 200 ; the intelligent control system 200 is connected to the chiller room system 100 . The fan coil unit 20 comprises a sprinkler valve 40 .

[0044] The intelligent control system 200 is configured to receive temperature data, determine whether a fire occurs in the area based on the temperature data, and if so, control the cold water system to provide water flow to the fan coil unit and control the sprinkler valve to open.

[0045] For example, if the temperature for a fire to occur is set to be higher than 50°C, the detection system 30 obtains the temperature of a certain area. If the obtained temperature data is 30°C, the detection system 30 transmits the temperature data to the intelligent control system 200. The intelligent control system determines that no fire has occurred in the corresponding area based on the temperature data and the set temperature for a fire to occur, and the intelligent control system does not take any action.

[0046] The detection system 30 obtains the temperature of a certain area. If the obtained temperature data is 60°C, the detection system 30 transmits the temperature data to the intelligent control system 200. The intelligent control system 200 determines whether a fire has occurred in the corresponding area based on the temperature data and the set fire temperature. The intelligent control system 200 controls the cold water system 10 to provide water flow to the fan coil unit 20, and controls the sprinkler valve 40 to open.

[0047] Among them, the fan coil unit is installed in each air-conditioned room as the terminal device of the chiller room system 100, and can process the air independently. The hot and cold water required for air processing is centrally prepared by the chiller room system 100 and provided to each fan coil. Working principle of fan coil unit: When chilled water or hot water flows through the coil tube, it exchanges heat with the air outside the tube, so that the air is cooled, dehumidified or heated to adjust the indoor air parameters. It is a commonly used cooling and heating terminal device.

[0048] It should be noted that according to the temperature of the fire, fires can be divided into three categories: low-temperature fires, medium-temperature fires and high-temperature fires. Among them, the temperature of low-temperature fires is below 200℃, the temperature of medium-temperature fires is between 200℃ and 500℃, and the temperature of high-temperature fires is above 500℃.

[0049] The system of linkage between the chiller room and the fire protection provided in some embodiments of the present application can promptly detect whether a fire occurs in the area through an intelligent control system, and can provide water flow to the fan coil unit by controlling the chilled water system, thereby extinguishing the fire in the area where the fire occurs.

[0050] like Figure 2 and Figure 3 As shown, the cold water system 10 includes: a cooling tower group 1, a cooling pump group 2, a chiller group 3 and a refrigeration pump group 4.

[0051] The input end of the cooling pump group 2 is connected to the output end of the cooling tower group 1; the first input end of the chiller 3 is connected to the output end of the cooling pump group 2, the first output end of the chiller 3 is connected to the input end of the cooling tower group, and the second output end of the chiller 3 is connected to the input end of the fan coil unit 20; the input end of the refrigeration pump group 4 is connected to the output end of the fan coil unit 20, and the output end of the refrigeration pump group 4 is connected to the second input end of the chiller 3.

[0052] Exemplarily, the cooling tower group 1 refers to a plurality of cooling towers, such as Figure 2 The first cooling tower 11 and the second cooling tower 12 in the figure; similarly, the cooling pump group 2 refers to a plurality of cooling pumps, such as Figure 2 The first cooling pump 21, the second cooling pump 22 and the third cooling pump 23; the chiller 3 refers to a plurality of chillers, for example Figure 2 The first chiller 31, the second chiller 32 and the third chiller 33; the refrigeration pump group 4 refers to a plurality of refrigeration pumps, such as Figure 2 The first freezing pump 41, the second freezing pump 42 and the third freezing pump 43 in.

[0053] Reference Figure 2 The input end of the first cooling tower 11 and the input end of the second cooling tower 12 are connected together; the output end of the first cooling tower 11 and the output end of the second cooling tower 12 are connected together.

[0054] The input end of the first cooling pump 21, the input end of the second cooling pump 22 and the input end of the third cooling pump 23 are connected together; the output end of the first cooling pump 21, the output end of the second cooling pump 22 and the output end of the third cooling pump 23 are connected together.

[0055] The first input end of the first chiller 31, the first input end of the second chiller 32 and the first input end of the third chiller 33 are connected together; the second input end of the first chiller 31, the second input end of the second chiller 32 and the second input end of the third chiller 33 are connected together; the first output end of the first chiller 31, the first output end of the second chiller 32 and the first output end of the third chiller 33 are connected together; the second output end of the first chiller 31, the second output end of the second chiller 32 and the second output end of the third chiller 33 are connected together.

[0056] In summary, referring to Figure 2, the chiller 3 transmits the generated 37℃ cooling water to the cooling tower group 1 for cooling. The 37℃ cooling water is cooled by the cooling tower group 1 and becomes 32℃ cooling water. Then the 32℃ cooling water is transmitted to the chiller 3 through the cooling pump group 2, and the cycle is completed.

[0057] The chiller 3 transmits the generated 7°C chilled water to the fan coil unit for air heat exchange to reduce the indoor temperature. The 7°C chilled water after heating becomes 12°C chilled water, and then the 12°C chilled water is transmitted to the chiller 3 via the refrigeration pump unit 4, and the cycle is completed.

[0058] The intelligent control system 200 is communicatively connected with the cooling tower group 1, the cooling pump group 2, the chiller 3 and the refrigeration pump group 4; the intelligent control system 200 is configured to control the cooling tower group 1, the cooling pump group 2 and the chiller 3 to be shut down, and control the refrigeration pump group 4 to be turned on when a fire occurs in the determined area.

[0059] For example, if the temperature for a fire to occur is set to be higher than 50°C, the detection system 30 obtains the temperature of a certain area. If the obtained temperature data is 30°C, the detection system 30 transmits the temperature data to the intelligent control system 200. The intelligent control system determines that no fire has occurred in the corresponding area based on the temperature data and the set temperature for a fire to occur, and the intelligent control system does not take any action.

[0060] The detection system 30 obtains the temperature of a certain area. If the obtained temperature data is 60°C, the detection system 30 transmits the temperature data to the intelligent control system 200. The intelligent control system 200 determines that a fire has occurred in the corresponding area based on the temperature data and the temperature at which the fire is set. The intelligent control system 200 controls the cold water system 10 to provide water flow to the fan coil unit 20, and controls the sprinkler valve 40 to open. The intelligent control system 200 controls the cooling tower group 1, the cooling pump group 2 and the chiller 3 to close, and controls the freezing pump group 4 to open. In this way, the water in the cold water system 10 and the fan coil unit 20 can be used to extinguish the fire to prevent danger.

[0061] Among them, the chiller uses an evaporator to exchange heat between water and refrigerant. The refrigerant absorbs heat from the high-temperature chilled water (12°C) in the evaporator, cools the water to produce low-temperature chilled water (7°C), and then brings the heat to the condenser through the action of the compressor. The refrigerant and the low-temperature cooling water exchange heat, so that the cooling water absorbs the heat and then takes the heat out through the water pipe to the external cooling tower for heat dissipation.

[0062] In some embodiments, the chiller is a water-cooled chiller.

[0063] like Figure 3As shown, the chiller 3 includes: an evaporator 60 , a compressor 70 , a condenser 80 and a first filter 90 .

[0064] Among them, the first input end of the evaporator 60 is connected to the output end of the first filter 90, and is also connected to the output end of the compressor 70. The second input end of the evaporator 60 is connected to the output end of the refrigeration pump 4. The first output end of the evaporator 60 is connected to the input end of the compressor 70, and the second output end of the evaporator 60 is connected to the fan coil unit 20; the first input end of the condenser 80 is connected to the output end of the compressor 70, the second input end of the condenser 80 is connected to the output end of the cooling pump 2, the first output end of the condenser 80 is connected to the input end of the first filter 90, and the second output end of the condenser 80 is connected to the input end of the cooling tower 1.

[0065] The specific working process is: at the beginning, the low-temperature and low-pressure refrigerant gas after evaporation and refrigeration is sucked into the compressor 70, and then compressed into high-temperature and high-pressure gas and sent to the condenser 80; the high-pressure and high-temperature gas is cooled by the condenser 80 to condense the gas into a normal temperature and high-pressure liquid; when the normal temperature and high-pressure liquid is throttled to become a low-temperature and low-pressure wet steam, it flows into the evaporator 60, absorbs the heat of the chilled water in the evaporator 60 to lower the water temperature; the evaporated refrigerant is sucked back into the compressor 70, and the next refrigeration cycle is repeated.

[0066] Among them, the refrigeration pump 4 is used to circulate chilled water, and the chilled water enters the fan coil unit 20 to exchange heat with the indoor room, thereby reducing the indoor air temperature and achieving the purpose of refrigeration; the cooling pump 2 is used to circulate cooling water, and the chilled water takes away the indoor heat, and transfers the heat to the cooling water through the refrigerant in the main unit. The cooling pump presses the heated cooling water into the cooling tower 1 to exchange heat with the atmosphere, and after cooling, it is sent back to the condenser 80 in the chiller 3 to continue heat exchange.

[0067] like Figure 4 and Figure 5 As shown, the cold water system 10 also includes: a make-up water pump 5 and a make-up water valve 6; the input end of the make-up water pump 5 is connected to the water source 7; the input end of the make-up water valve 6 is connected to the output end of the make-up water pump 5, and the output end of the make-up water valve 6 is connected to the input end of the refrigeration pump group 4.

[0068] The intelligent control system 200 is in communication connection with the water supply pump 5 and is in communication connection with the water supply valve 6. The intelligent control system 200 is configured to control the water supply pump and the water supply valve to open when a fire is detected in the area.

[0069] According to the above, the chilled water system 10 and the fan coil unit 20 can form a cycle, that is, under ideal conditions, the total amount of water in the chilled water system 10 and the fan coil unit 20 is constant.

[0070] The detection system 30 obtains the temperature of a certain area. If the obtained temperature data is 60°C, the detection system 30 transmits the temperature data to the intelligent control system 200. The intelligent control system 200 determines that a fire has occurred in the corresponding area based on the temperature data and the temperature at which the fire has occurred. The intelligent control system 200 controls the cold water system 10 to provide water flow for the fan coil unit 20, and controls the sprinkler valve 40 to open. The intelligent control system 200 controls the cooling tower group 1, the cooling pump group 2 and the chiller 3 to close, and controls the freezing pump group 4 to open. Then the intelligent control system 200 controls the water supply pump 5 and the water supply valve 6 to open. Since the input end of the water supply pump 5 is connected to the water source 7, water for fire extinguishing can be continuously provided to the sprinkler valve in the fan coil unit 20. In this way, the water in the cold water system 10 and the fan coil unit 20 can be used for fire extinguishing to prevent danger. Among them, the temperature of the water used for fire extinguishing is the temperature of the water source 7 itself.

[0071] In some embodiments, the intelligent control system 200 determines that a fire has occurred in the corresponding area according to the temperature data and the temperature at which the fire has occurred. The intelligent control system 200 controls the cold water system 10 to provide water flow for the fan coil unit 20, and controls the sprinkler valve 40 to open. The intelligent control system 200 controls the cooling tower group 1 and the cooling pump group 2 to close, and controls the freezing pump group 4 and the chiller 3 to open. Then the intelligent control system 200 controls the water supply pump 5 and the water supply valve 6 to open. Since the input end of the water supply pump 5 is connected to the water source 7, water for fire extinguishing can be continuously provided to the sprinkler valve in the fan coil unit 20. In this way, the water in the cold water system 10 and the fan coil unit 20 can be used for fire extinguishing to prevent danger from occurring. Among them, the temperature of the water used for fire extinguishing is the temperature of the chilled water after being cooled by the chiller 3. This temperature is lower than the temperature of the water source, which can accelerate the extinguishing of the fire source.

[0072] like Figure 6 and Figure 7 As shown, in some embodiments, the cold water system 10 further includes: a second filter 91. The input end of the second filter 91 is connected to the water source 7, and the output end of the second filter 91 is connected to the input end of the water supply valve 6.

[0073] The second filter 91 is configured to filter out impurities in the water source 7 to prevent the impurities from damaging the chiller room system 100 .

[0074] The intelligent control system 200 is also configured to receive temperature data and determine whether the fire in the area has been eliminated based on the temperature data; if so, the sprinkler valve 40 of the fan coil unit 20 in the control area is closed, the water supply pump 5 and the water supply valve 6 are controlled to be closed; and the cooling tower group 1, the cooling pump group 2 and the chiller 3 are controlled to be turned on.

[0075] That is to say, in the first case: the detection system 30 obtains the temperature of a certain area. If the obtained temperature data is 60°C, the detection system 30 transmits the temperature data to the intelligent control system 200. The intelligent control system 200 determines whether a fire has occurred in the corresponding area based on the temperature data and the set fire temperature.

[0076] After the intelligent control system 200 controls the cold water system 10 to provide water flow to the fan coil unit 20 and controls the sprinkler valve 40 to open for a period of time, the intelligent control system 200 controls the cooling tower group 1, the cooling pump group 2 and the chiller 3 to close, and controls the freezing pump group 4 to open. Then the intelligent control system 200 controls the water supply pump 5 and the water supply valve 6 to open.

[0077] The detection system 30 obtains the temperature of a certain area. If the obtained temperature data is lower than 50°C, the intelligent control system 200 determines that the fire in the corresponding area has been extinguished based on the temperature data and the set fire temperature. The intelligent control system 200 controls the sprinkler valve 40 of the fan coil unit 20 in the control area to close, controls the water supply pump 5 and the water supply valve 6 to close; and controls the cooling tower group 1, the cooling pump group 2 and the chiller 3 to start.

[0078] The second situation: the detection system 30 obtains the temperature of a certain area. If the obtained temperature data is 60°C, the detection system 30 transmits the temperature data to the intelligent control system 200. The intelligent control system 200 determines whether a fire has occurred in the corresponding area based on the temperature data and the set fire temperature.

[0079] After the intelligent control system 200 controls the chilled water system 10 to provide water flow to the fan coil unit 20 and controls the sprinkler valve 40 to open for a period of time, the intelligent control system 200 controls the cooling tower group 1 and the cooling pump group 2 to close, and controls the freezing pump group 4 and the chiller 3 to open. Then the intelligent control system 200 controls the water supply pump 5 and the water supply valve 6 to open.

[0080] The detection system 30 obtains the temperature of a certain area. If the obtained temperature data is lower than 50°C, the intelligent control system 200 determines that the fire in the corresponding area has been extinguished based on the temperature data and the set fire temperature. The intelligent control system 200 controls the sprinkler valve 40 of the fan coil unit 20 in the control area to close, controls the water supply pump 5 and the water supply valve 6 to close; and controls the cooling tower group 1 and the cooling pump group 2 to open.

[0081] In some embodiments, the intelligent control system is configured to receive temperature data and determine whether a fire has occurred in an area based on the temperature data. Specifically, it is configured to receive temperature data and determine whether a fire has occurred in an area based on a comparison between the temperature data and a set temperature.

[0082] For example, if the temperature for a fire to occur is set to be higher than 50°C, that is, the set temperature is 50°C. The detection system 30 obtains the temperature of a certain area. If the obtained temperature data is 30°C, the detection system 30 transmits the temperature data to the intelligent control system 200. The intelligent control system compares the temperature data with the set temperature. If 50°C>30°C, there is no fire in the corresponding area, and the intelligent control system 200 does not take any action.

[0083] For example, if the temperature for a fire to occur is set to be higher than 50°C, the set temperature is 50°C. The detection system 30 obtains the temperature of a certain area. If the temperature data obtained is 60°C, the detection system 30 transmits the temperature data to the intelligent control system 200. The intelligent control system compares the temperature data with the set temperature. If 50°C < 60°C, a fire occurs in the corresponding area. The intelligent control system 200 controls the cold water system 10 to provide water flow to the fan coil unit 20 and controls the sprinkler valve 40 to open. The intelligent control system 200 controls the cooling tower group 1, the cooling pump group 2 and the chiller 3 to close, and controls the freezing pump group 4 to open. Then the intelligent control system 200 controls the water supply pump 5 and the water supply valve 6 to open.

[0084] like Figure 8 As shown, the fan coil unit 20 includes: multiple fan coils, each fan coil corresponds to a sub-area; the detection system includes: multiple detection subsystems, each detection subsystem is used to obtain temperature data of a sub-area; the fan coil and the detection subsystem correspond to the same sub-area; the intelligent control system is connected to the sprinkler valve and also connected to the detection system.

[0085] That is to say, one fan coil unit corresponds to one sprinkler valve, that is, the fan coil unit 20 is equivalent to including a plurality of sprinkler valves.

[0086] The intelligent control system receives temperature data, and determines whether a fire has occurred in an area based on a comparison between the temperature data and a set temperature. The intelligent control system is specifically configured to: receive multiple temperature data transmitted by multiple detection subsystems, and determine whether a fire has occurred in an area when N temperature data are greater than a set temperature; wherein N>2.

[0087] For example, if the temperature for a fire to occur is set to be higher than 50°C, that is, the set temperature is 50°C. The detection system 30 obtains the temperature of the area, and the temperature data of multiple sub-areas obtained are all 30°C. The detection system 30 transmits the temperature data to the intelligent control system 200, and the intelligent control system 200 compares the temperature data with the set temperature. If 50°C>30°C, there is no fire in the corresponding area, and the intelligent control system 200 does not take any action. Alternatively, the temperature data of multiple sub-areas are all lower than 50°C.

[0088] For example, if the temperature for a fire to occur is set to be higher than 50°C, that is, the set temperature is 50°C. The detection system 30 obtains the temperature of a certain area, and the obtained temperature data of the first sub-area is 60°C, and the temperatures of the other sub-areas are all lower than 50°C. At this time, the intelligent control system 200 determines that there is no fire, but will display the abnormal temperature of the first sub-area, which requires further processing by the staff.

[0089] For example, if the temperature for setting a fire is higher than 50°C, the set temperature is 50°C. The detection system 30 obtains the temperature of a certain area, and the obtained temperature data of the first sub-area is 60°C, the temperature data of the second sub-area is 70°C, and the temperature data of the third sub-area is 65°C, that is, N>2 is satisfied, and the temperature data of the remaining sub-areas are all lower than 50°C; the detection system 30 transmits the temperature data to the intelligent control system 200, and the intelligent control system compares the temperature data with the set temperature, and it can be known that the corresponding first sub-area, the second sub-area, and the third sub-area have a fire. The intelligent control system 200 controls the cold water system 10 to provide water flow for the fan coil unit 20, and controls the sprinkler valve 40 to open. The intelligent control system 200 controls the cooling tower group 1, the cooling pump group 2, and the chiller 3 to close, and controls the freezing pump group 4 to open. Then the intelligent control system 200 controls the water supply pump 5 and the water supply valve 6 to open.

[0090] In some embodiments, the intelligent control system 200 is further configured to, when it is determined that a fire has occurred in a region, determine the sub-region where the fire has occurred, and control the sprinkler valves of the fan coil units corresponding to the sub-region to open.

[0091] For example, if the temperature for setting a fire is higher than 50°C, the set temperature is 50°C. The detection system 30 obtains the temperature of a certain area, and the obtained temperature data of the first sub-area is 60°C, the temperature data of the second sub-area is 70°C, and the temperature data of the third sub-area is 65°C, that is, N>2 is satisfied, and the temperature data of the remaining sub-areas are all lower than 50°C; the detection system 30 transmits the temperature data to the intelligent control system 200, and the intelligent control system compares the temperature data with the set temperature, and it can be known that the corresponding first sub-area, second sub-area, and third sub-area have a fire. The intelligent control system 200 controls the cold water system 10 to provide water flow for the fan coil unit 20, and controls the sprinkler valve of the first sub-area, the sprinkler valve of the second sub-area, and the sprinkler valve of the third sub-area to open. The intelligent control system 200 controls the cooling tower group 1, the cooling pump group 2, and the chiller 3 to close, and controls the freezing pump group 4 to open. Then the intelligent control system 200 controls the water supply pump 5 and the water supply valve 6 to open.

[0094] For example, if the detection system 30 includes multiple temperature sensors, the multiple temperature sensors correspond to the multiple sub-regions one by one, obtain the temperatures of the multiple sub-regions, and transmit the temperature data to the intelligent control system 200.

[0095] For example, if the detection system 30 includes a plurality of wire controllers A, the plurality of wire controllers correspond to the plurality of sub-regions one by one, obtain the temperatures of the plurality of sub-regions, and transmit the temperature data to the intelligent control system 200 .

[0097] The detection system 30 includes a human sensing system, which is configured to obtain personnel information in the area and transmit the personnel information to the intelligent control system 200 ; the intelligent control system 200 is configured to transmit the personnel information to the fire protection system 300 .

[0098] The personnel information refers to the number and posture of personnel in a certain area.

[0099] For example, if the temperature for a fire to occur is set to be higher than 50°C, that is, the set temperature is 50°C. The detection system 30 obtains the temperature of a certain area, and the obtained temperature data of the first sub-area is 60°C, the temperature data of the second sub-area is 70°C, and the temperature data of the third sub-area is 65°C, that is, N>2 is satisfied, and the temperature data of the remaining sub-areas are all lower than 50°C; at the same time, the human sensing system detects that there are five people in the second sub-area, and the five people are all in a crawling posture.

[0100] The detection system 30 transmits the temperature data and personnel information to the intelligent control system 200. The intelligent control system compares the temperature data with the set temperature and finds that fires have occurred in the corresponding first sub-area, second sub-area, and third sub-area. The intelligent control system 200 controls the cold water system 10 to provide water flow to the fan coil unit 20, and controls the sprinkler valves of the first sub-area, the second sub-area, and the third sub-area to open. At the same time, the intelligent control system 200 transmits the personnel information to the fire protection system 300, and promptly notifies the firefighters or security personnel to rescue the five trapped people.
