detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

In the following description, the use of suffixes such as “module”, “component”, or “unit” for indicating elements is merely for the benefit of the description of the present invention, and it does not have a specific meaning itself. Therefore, "modules," "components," or "units" can be used in combination.

In order to solve the potential safety hazard caused by the refrigerant leakage of the unit, an embodiment of the present invention provides a unit. As shown in FIG. 1, the unit includes: a refrigerant detection device 1, a main controller 2,

The refrigerant detection device 1 is located at the air outlet 3 of the unit and is used to detect the refrigerant concentration in the air at the air outlet 3, and sends an abnormal signal to the main controller 2 when the refrigerant concentration exceeds the refrigerant threshold;

The main controller 2 is connected to the refrigerant detection device 1 and is used to trigger an emergency protection mode after receiving an abnormal signal.

Therefore, when a refrigerant leakage is detected, an emergency protection mode can be triggered to ensure user safety, reduce potential safety hazards, and increase the safety factor of the unit.

In a possible implementation manner, the main controller 2 is further configured to control the entire unit to operate normally when the refrigerant concentration does not exceed the refrigerant threshold. That is, if the refrigerant detecting device 1 finds no abnormality during the startup operation of the unit, the unit can operate normally.

In a possible implementation manner, the unit further includes: a blower device 4 and a main controller 2 connected to the blower device 4 for sending a control instruction to the blower device 4 after the emergency protection mode is triggered; The device 4 is used for stopping the operation according to the control instruction. As shown in FIG. 2, the air supply device 4 includes a fan 4 and / or a damper. The air-supplying device in FIG. 2 is a fan, and the same reference numerals are used.

It can be understood that when it is detected that the refrigerant concentration exceeds a preset threshold, an emergency protection mode may be activated, specifically: controlling the air supply device 4 to be closed, that is, controlling the air supply fan 4 and / or the air valve to be closed. Among them, the fan 4 and the damper can be used together. When the refrigerant leaks, both of them can be closed to further ensure that the refrigerant will not flow to the passenger area. When only the fan 4 is closed, the solution of the present application can also be implemented because the air flow is extremely small. If only the air valve is closed, it is equivalent to directly closing the outlet. At this time, whether the fan 4 is closed does not affect the solution of the application. .

In a possible implementation manner, as shown in FIG. 2, the unit further includes: a compressor 5, a main controller 2, connected to the compressor 5, and used to send a control instruction to the compressor 5 after the emergency protection mode is triggered. ; Compressor 5 for stopping operation according to the control instruction. The main controller 2 is also used to control the entire unit to stop running after the emergency protection mode is triggered. The above two methods can be implemented in one of two ways. The present invention does not limit this. Shutting down the compressor 5 or stopping the entire unit of the control unit can further ensure that the refrigerant will not flow to the passenger area and ensure the safety of the user.

In a possible implementation manner, the unit further includes: a refrigerant isolation plate 6, which is arranged around the vibration components of the unit and the connecting pipes of the vibration components to form a refrigerant isolation zone. The unit also includes: an exhaust fan 7 (that is, a refrigerant leakage maintenance exhaust fan shown in FIG. 2), which is arranged on the refrigerant isolating plate 6; a main controller 2, which is connected to the exhaust fan 7 and is used to trigger an emergency protection mode, Send a control instruction to the exhaust fan 7; the exhaust fan 7 is used to discharge the refrigerant in the refrigerant isolation zone according to the control instruction. The refrigerant isolation plate 6 is sealed with a sealing strip and / or a sealing plate. The vibration component includes at least one of the following: a compressor 5 and a condenser 8.

It can be understood that the refrigerant isolating plate 6 can surround the compressor 5, the condenser shell tube 8 (condenser 8) and the connecting pipelines of the two, and the adjacent pipelines and other areas where the refrigerant is easy to leak on the vibration source side, so as to carry out the structure. Protection. Taking the unit as a water-cooled direct cooling air-conditioning unit as an example, its structure is shown in Figure 2, including: return air port 9, compressor 5, condenser shell tube 8 (condenser 8), refrigerant leakage maintenance exhaust fan 7 (exhaust fan 7) ), Electronic expansion valve 11, refrigerant isolation plate 6, direct cooling evaporator 10, distributed air blower 4 (the number can be one or multiple), refrigerant detection device 1, air outlet 3, and can be adjusted according to The effect is divided into three sections, namely the main section, the evaporation section and the air supply section.

The evaporator 10 may be a direct expansion evaporator. The cooled cold air is then sent directly to the end of the site through the distributed air blower through the air outlet 3. Therefore, the arrangement of the refrigerant isolating plate 6 can make the return air reach the evaporator 10 through the upper space of the refrigerant isolating plate 6 to prevent the refrigerant from flowing with the air to the air supply duct, thereby causing a hidden safety hazard.

It can be understood that the stress and strain effects at the pipelines of the vibration parts such as the compressor 5 and the condenser 8 and their accessories are strong, and welding trachoma is easy to occur. This part of the area is easy to leak refrigerant, so special space sealing treatment is required. For example, the refrigerant isolating plate 6 may be processed by using a sealing plate and a sealing strip, thereby preventing a large amount of refrigerant from leaking to the air supply area, and also preventing the refrigerant from leaking to all parts of the unit, making it difficult for subsequent maintenance work.

Among them, the refrigerant leakage maintenance exhaust fan 7 is located on any one of the isolation plates in the isolation area, and a suitable opening can be opened at the position where the refrigerant leakage exhaust fan 7 is located according to its size and model.

It should be noted that the unit in the embodiment of the present application may be a water-cooled direct cooling air-conditioning unit, and may be applied to a station of an underground track. And the condenser 8 may be a shell and tube condenser 8.

In a possible implementation manner, the refrigerant detecting device 1 is further configured to issue a fault alarm signal when the refrigerant concentration exceeds the refrigerant threshold.

It is also possible to set a separate fault alarm device, which will alarm after the main controller receives the abnormal signal.

In a possible implementation manner, the main controller 2 is further configured to start a maintenance program after receiving the abnormal signal. After receiving the abnormal signal, it can also send a signal to the main console (for example, the main console in the subway) to notify the main console to start the maintenance program.

In related technologies, the crew cannot determine whether the refrigerant is in a normal state, and after a large amount of refrigerant leaks, it will directly enter the passenger area with the blower, causing passenger panic and causing public safety issues. At the time of maintenance, a large amount of refrigerant has leaked into the machine room or the inside of the sample casing, which caused difficulties in the maintenance. In this application, the refrigerant detection device 1 can detect the refrigerant concentration in the air of the air outlet 3 in real time or in different periods, and communicates with the main controller 2 so that the main controller 2 can accurately and timely know the abnormality of the refrigerant and reduce Hidden safety hazards that may arise when refrigerant leaks, the use of isolation plate 6 prevents refrigerant from leaking around the unit, and the fault alarm device can promptly notify the console to start the maintenance program, and start the refrigerant isolation plate before maintenance.
