Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning systems, and particularly relates to an air conditioning system with a bypass switching function. Background Art

[0002] An air conditioning system is used to improve indoor air. Its principle is to set an air optimization component in the air inlet flow channel to improve the air passing through the air inlet flow channel to meet the indoor requirements.

[0003] In order to meet the requirements of different working conditions, the air conditioning system often needs to switch the start and stop of the air optimization components in the air inlet flow channel according to different working conditions. For example, the cooling and heating functions are switched according to the seasonal changes.

[0004] However, when a certain air optimization component in the air inlet flow channel stops working, it still occupies the space of the flow channel, which will hinder the air flow in the air inlet flow channel, resulting in a decrease in the air intake efficiency. In order to ensure the air intake velocity, the fan energy consumption will be excessively consumed. Content of the Utility Model

[0005] To overcome the deficiencies of the above-mentioned prior art, the utility model provides an air conditioning system with a bypass switching function. Air can bypass the air optimization unit that is switched to stop using, thereby reducing the flow resistance in the main air inlet flow channel and improving the air intake efficiency of the air conditioning system.

[0006] To achieve the above object, the utility model is realized by the following technical solutions:

[0007] An air conditioning system with a bypass switching function includes a main air inlet flow channel, in which several air optimization units are arranged at intervals along the extending direction of the main air inlet flow channel; it further includes a bypass flow channel, and several bypass ports are arranged between the bypass flow channel and the main air inlet flow channel. Valves are arranged on the bypass ports; the bypass ports are arranged on both sides of the air optimization units.

[0008] Based on the above structure, the principle of the air conditioning system with a bypass switching function is as follows: The untreated air is sent into the main inlet air flow path by a fan, and after being optimized by the air optimization unit, it is discharged into the room. When the valves on a pair of bypass ports are opened, the air can enter the bypass flow path from the main inlet air flow path, bypass the air optimization unit arranged between the pair of opened bypass ports, and then enter the main inlet air flow path. Since the air optimization unit is arranged in the main inlet air flow path and has a flow blocking effect, when one air optimization unit is deactivated according to the working conditions, the bypass ports on both sides of this air optimization unit are opened. At this time, the bypass flow path between the pair of bypass ports forms a parallel connection with the main inlet air flow path corresponding to this air optimization unit. Therefore, the air can bypass this air optimization unit, thus reducing the flow resistance in the main inlet air flow path and improving the air intake efficiency of the air conditioning system. It is especially applicable to the air conditioning system in which the air optimization unit in the main inlet air flow path is selected according to the working conditions. It can save the energy consumption of the fan on the premise of ensuring the air intake velocity.

[0009] Furthermore, in the air conditioning system with a bypass switching function described in the present application, the bypass flow path is arranged above the main inlet air flow path. As a preferred solution of the present application, that is, the valves on the bypass ports are arranged at the top of the main inlet air flow path.

[0010] Furthermore, in the air conditioning system with a bypass switching function described in the present application, the air optimization unit includes at least one of a refrigeration unit, a heating unit, and a spray purification unit.

[0011] Furthermore, in the air conditioning system with a bypass switching function described in the present application, when the air conditioning system is operating, the air optimization unit needs to be switched on or off according to the preset working conditions, and each air optimization unit is arranged between a pair of adjacent bypass ports. As a preferred solution of the present application, it can be realized that when the air conditioning system is operating, the bypass flow path corresponding to each deactivated air optimization unit is opened. It should be noted that for the air optimization actuators that are always open under various working conditions, there is no need to set bypass ports at both ends.

[0012] Furthermore, in the air conditioning system with a bypass switching function described in the present application, the bypass flow path is arranged in an integral pipeline, and an isolation valve is arranged in the bypass flow path, and the isolation valve is arranged between a pair of bypass ports. As a preferred solution of the present application, when the isolation valve is closed, the bypass flow path corresponding to the air optimization unit between the pair of bypass ports on both sides of the isolation valve is in a cut-off state.

[0013] Further, in an air conditioning system with a bypass switching function according to the present application, a normally open module is provided in the main air inlet flow channel, and the normally open module is arranged outside the bypass flow channel. As a preferred solution of the present application, the normally open module is a module that must participate in the operation under any working conditions when the air conditioning system is operating.

[0014] As can be seen from the above technical solutions, the present utility model has the following beneficial effects:

[0015] The present utility model provides an air conditioning system with a bypass switching function. When the air optimization unit is stopped according to the working conditions, by controlling the opening and closing of the valve on the bypass port, the air flow organization enters the bypass flow channel, thereby reducing the flow resistance in the main air inlet flow channel and improving the air intake efficiency of the air conditioning system. It is especially suitable for an air conditioning system in which the air optimization unit in the main air inlet flow channel is selected according to the working conditions. It can save the energy consumption of the fan while ensuring the air intake velocity. Combining with the usage conditions of different seasonal working conditions, by controlling the opening and closing of the valve on the bypass port, the optimization of the operation resistance of the unit is realized, and the energy-saving effect is achieved. When dealing with multiple working conditions, it has the advantage of being able to flexibly customize the energy-saving scheme. Description of the Drawings

[0018] Combined with Figure 1 As shown in an air conditioning system with a bypass switching function, it includes a main air inlet flow channel 1, and several air optimization units are provided in the main air inlet flow channel 1, and the several air optimization units are arranged at intervals along the extending direction of the main air inlet flow channel 1; it further includes a bypass flow channel 2, and several bypass ports 21 are provided between the bypass flow channel 2 and the main air inlet flow channel 1, and valves are provided on the bypass ports 21; the bypass ports 21 are arranged on both sides of the air optimization unit.

[0019] Based on the above structure, the principle of the air conditioning system with a bypass switching function is as follows: The untreated air is sent into the main inlet air flow channel 1 by a fan, and after being optimized by the air optimization unit, it is discharged into the room. When the valves on a pair of bypass ports 21 are opened, the air can enter the bypass flow channel 2 from the main inlet air flow channel 1, bypass the air optimization unit arranged between the pair of opened bypass ports 21, and then enter the main inlet air flow channel 1. Since the air optimization unit is arranged in the main inlet air flow channel 1 and has a flow resistance effect, when one air optimization unit is deactivated according to the working conditions, the bypass ports 21 on both sides of this air optimization unit are opened. At this time, the bypass flow channel 2 between the pair of bypass ports 21 and the main inlet air flow channel 1 corresponding to this air optimization unit form a parallel connection. Therefore, the air can bypass this air optimization unit, thus reducing the flow resistance in the main inlet air flow channel 1 and improving the air intake efficiency of the air conditioning system. It is especially applicable to the air conditioning system in which the air optimization unit in the main inlet air flow channel 1 is selected according to the working conditions. It can save the energy consumption of the fan on the premise of ensuring the air intake velocity.

[0020] In this embodiment, the bypass flow channel 2 is arranged above the main inlet air flow channel 1.

[0021] That is, the valves on the bypass ports 21 are arranged at the top of the main inlet air flow channel 1. Specifically, the extending direction of the bypass flow channel 2 corresponds to the extending direction of the main inlet air flow channel 1.

[0022] In this embodiment, the air optimization unit includes at least one of a refrigeration unit 3, a heating unit 4, and a spray purification unit 5.

[0023] In this embodiment, when the air conditioning system works, the air optimization unit needs to be switched on or off according to the preset working conditions. Each air optimization unit is arranged between a pair of adjacent bypass ports 21. It can be realized that when the air conditioning system works, the bypass flow channel 2 corresponding to each deactivated air optimization unit is opened. It should be noted that for the air optimization actuators that are always open under various working conditions, there is no need to set bypass ports 21 at both ends.

[0024] In this embodiment, the air optimization unit includes a first refrigeration unit 31, a heating unit 4, a spray purification unit 5, and a second refrigeration unit 32 arranged in sequence. The corresponding bypass ports 21 are the first bypass port 211, the second bypass port 212, the third bypass port 213, the fourth bypass port 214, and the fifth bypass port 215 in sequence. The isolation valve 22 is arranged between the third bypass port 213 and the fourth bypass port 214. The refrigeration power of the second refrigeration unit 32 is greater than that of the first refrigeration unit 31.

[0025] In this embodiment, the bypass flow channel 2 is arranged in an integral pipeline, and an isolation valve 22 is arranged in the bypass flow channel 2, and the isolation valve 22 is arranged between a pair of bypass ports 21. When the isolation valve 22 is closed, the bypass flow channel 2 corresponding to the air optimization unit between the pair of bypass ports 21 on both sides of the isolation valve 22 is in a cut-off state.

[0026] In this embodiment, a normally open module is provided in the main inlet flow channel 1 , and the normally open module is arranged outside the bypass flow channel 2 .

[0027] The normally open module is a module that must be involved in the operation of the air conditioning system under any working conditions. Specifically, the normally open module includes a fan module 61 and a filter module 62 .

[0028] The air conditioning system includes the following working conditions:

[0029] 1. First transitional working condition: only the spray purification unit 5 works, and the other air optimization units stop working; the second bypass port 212 is closed, the other bypass ports 21 are opened, and the isolation valve 22 is closed;

[0030] 2. Summer working condition: only the heating unit 4 stops working, and the other air optimization units work; the first bypass port 211, the fourth bypass port 214 and the fifth bypass port 215 are closed, the other bypass ports 21 are opened, and the isolation valve 22 is closed;

[0031] 3. Second transitional working condition: the spray purification unit 5 and the second refrigeration unit 32 are working, and the other air optimization units are stopped; the second bypass port 212, the fourth bypass port 214 and the fifth bypass port 215 are closed, the other bypass ports 21 are opened, and the isolation valve 22 is closed;
