Description
Technical field
This utility model relates to animal cultivation technical field, and clean room's supply air system is used in especially a kind of test.
Background technology
In the breeding process of test animal, for avoiding animal to catch an illness, general build clean room that having is isolated from the outside comes for culture experiment with animal, therefore, air humidity in clean room, temperature, air pressure etc. need strictly to control, to guarantee the health of test animal.In prior art, clean room utilizes the outside heat exchange unit arranged of culturing chamber to implement the humidity in clean room and the regulation of temperature mostly, the air in the heat exchange unit extraction external world carries out heat exchange, the gas carrying out heat exchange is passed through in clean room, thus implement clean room is supplied, and then the parameter such as temperature in regulation clean room, humidity, air pressure, but clean room is in the state more closed, simply simple supplying in clean room, purify the air of a room and can not get exchange, it is easy to grow pathogenic bacteria, it is difficult to ensure that the health of indoor culture animal.
Utility model content
The purpose of this utility model is just to provide a kind of clean room supply air system, it is possible to the air in culturing chamber is circulated regulation, it is ensured that the health of animal in culturing chamber.
To achieve these goals, the technical solution adopted in the utility model is: a kind of clean room supply air system, including the heat exchange unit for air being carried out heat exchange operation, the air-supply end of heat exchange unit is connected with clean room by pipeline, clean room is provided with return air inlet for being discharged by the air in clean room.
What compared with prior art this utility model possessed has the technical effect that utilizing the return air inlet being arranged in clean room to implement the air in clean room regulates, the air capacity being passed through in clean room according to heat exchange unit, determine the air output of return air inlet, and then conveniently implement the operation of the regulation to the air pressure in clean room, temperature, humidity, make the air in clean room be in optimal state, reduce the probability of the sufferer of animal.
Accompanying drawing explanation
Fig. 1 is the cutting structural representation of heat exchange unit and basement；
Fig. 2 is the structure diagram of air circulation system.
Detailed description of the invention
In conjunction with Fig. 1 and Fig. 2, to the explanation further of this utility model work:
A kind of clean room supply air system, including the heat exchange unit 10 for air carries out heat exchange operation, the air-supply end of heat exchange unit 10 is connected with clean room 20 by pipeline, clean room 20 is provided with return air inlet for being discharged by the air in clean room 20.
Abandon in prior art, the air of clean room 20 is in the drawback under more closed state all the time, utilize the return air inlet being arranged in clean room 20 to implement the air in clean room 20 to regulate, it is passed through the air capacity in clean room 20 according to heat exchange unit 10, determine the air output of return air inlet, and then conveniently implement the operation of the regulation to the air pressure in clean room 20, temperature, humidity so that the air in clean room 20 is in optimal state, reduces the probability of the sufferer of animal.
As preferred version of the present utility model, the return air inlet of described clean room connects with backwind tube 30, and the outlet air end of backwind tube 30 connects with the air intake of heat exchange unit 10.There is certain temperature in the air itself owing to discharging in clean room 20, the air that backwind tube 30 is discharged is passed directly into the air intake of heat exchange unit 10, it is possible to reduces the power consumption of heat exchange unit itself.
As this utility model more preferably scheme, described heat exchange unit 10 is arranged on above earth's surface, the earth's surface of heat exchange unit 10 is arranged with basement 40, the air intake of described heat exchange unit 10 connects with blast pipe 11, in blast pipe 11 room located underground 40, the outlet air end of backwind tube 30 is passed through basement 40 and connects with blast pipe 11.Owing to the air themperature four seasons of basement 40 are the most constant, when in summer, owing to extraneous temperature is higher, the air themperature extracted by clean room 20 is higher, connect with the blast pipe 11 of heat exchange unit 10 after being lowered the temperature by basement 40, the power consumption of heat exchange unit can be reduced further, in like manner, when being in winter, extraneous temperature is relatively low, the air themperature extracted by clean room 20 is relatively low, connects with the blast pipe 11 of heat exchange unit 10 after being preheated by basement 40, it is possible to reduce the power consumption of heat exchange unit 10 further.
Described backwind tube 30 connects with the pipe shaft of blast pipe 11, the pipe end of blast pipe 11 and underground
Room 40 connects, and basement 40 also one end with fresh wind tube 50 connects, the other end of fresh wind tube 50 and atmosphere.For guaranteeing whole blood circulation air quality, extraneous fresh air is introduced in whole air circulation system by fresh wind tube 50, it is thus possible to guarantee the air quality of air circulation system, similarly, the air by the external world of fresh wind tube 50 introduces basement 40, thus can reduce the power consumption of heat exchange unit 10 further.
Between how described clean room 20 is distributed, each the corresponding heat exchange unit 10 in clean room 20, the backwind tube 30 of each clean room 20 connects with the blast pipe 11 of respective heat exchange unit 10.
Also each extend on the pipeline of the outlet air end of each heat exchange unit 10 and be provided with communicating pipe 12, be interconnected each communicating pipe 12 and realize the connection of outlet air end pipeline of each heat exchange unit 10.When multiple clean room's 20 corresponding multiple heat exchange unit 10, when one or more heat exchange unit 10 cannot work, as long as guaranteeing that one of them heat exchange unit 10 can work, the outlet air end of the heat exchange unit 10 that can work is by flowing to the pipeline 13 of the outlet air end of each heat exchange unit 10 communicating pipe 12, can supply each clean room 20, whole air circulation system can work on.
Owing to the animal of clean room 20 may be in again ill state, for avoiding the cross infection between each clean room 20, it is provided with the first control valve 60 of regulation air quantity described communicating pipe 12.The first control valve 60 on the communicating pipe 12 of the heat exchange unit 10 being in infection when the animal corresponding to clean room 20 is closed, so air in this clean room 20 would not enter in whole blood circulation, such that it is able to avoid the exchange of the air between clean room 20, it is to avoid cross infection.
For convenience of the regulation of the intake to clean room 20, the pipeline that the outlet air end of described heat exchange unit 10 connects with clean room 20 is provided with the second control valve 70 of regulation intake.
In like manner, for convenience of the regulation of the air output to clean room 20, described backwind tube 30 is provided with the 3rd control valve 80 of regulation air quantity.
