Vapor is blown by the wind turbine of refrigeration machine in laboratory, so as to fulfill the constant humidity in laboratory.This humidification side to laboratory
Formula has the following problems：
1st, vapor is formed using electrical heating heating water humidified to laboratory, it is necessary to heat the water to 100 DEG C or more
Vapor can be formed, energy consumption is big；
2nd, the vapor after heating is blown into laboratory by the wind turbine of refrigeration machine, and the wind that refrigeration machine is blown into laboratory is cold
Wind after the vapor of high temperature is mixed with the cold wind that refrigeration machine generates, will offset refrigeration machine and test indoor cold significantly, so as to
Influence the temperature case in laboratory；
3rd, high-temperature vapor will be condensed into water droplet after cold wind is run into cold, and the water that can be successfully entered laboratory humidification steams
Gas is less, the relatively low of humidification efficiency
Utility model content
In order to solve the above-mentioned technical problem, the purpose of this utility model is：A kind of laboratory constant humidity system of low energy consumption is provided
System.
Technical solution is used by the utility model：A kind of laboratory constant humidity system, includes and is arranged in laboratory
Refrigeration unit, include control circuit, sensible heat exchanger, breeze fan, exhaust fan, air-supply passage and air exhaust passage, institute
Air-supply passage is stated for being connected to the air outlet in laboratory, the air exhaust passage is used to be connected to the exhaust outlet in laboratory, described
Control circuit is respectively connected to breeze fan and exhaust fan, and the air outside laboratory passes sequentially through breeze fan, sensible heat changes
Hot device and air-supply passage are inputted to laboratory, and the air of the laboratory internal passes sequentially through air exhaust passage, sensible heat exchanger
It is exported with exhaust fan to outside laboratory.
Further, further included and be arranged at indoor first Temperature Humidity Sensor of experiment, the control circuit is connected to the
One Temperature Humidity Sensor.
Further, the second Temperature Humidity Sensor being arranged at outside laboratory is further included, the control circuit is connected to
Two Temperature Humidity Sensors.
Further, the breeze fan and exhaust fan are frequency conversion fan.
Further, further included and be arranged at the indoor electrical heating humidification device of experiment.
The beneficial effects of the utility model are：Not the characteristics of not exchanging using sensible heat exchanger inner exchanging heat but humidity,
Air-supply and air exhaust passage is used to be connected with laboratory, so as to fulfill the control to laboratory internal constant humidity, and not
It influences to test indoor temperature case, avoids unnecessary energy consumption.
Description of the drawings
Fig. 1 is the structure diagram of utility model of the present invention；
Fig. 2 is the structure diagram of utility model further embodiment of the present invention.
Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
With reference to Fig. 1, a kind of laboratory constant humidity system includes the refrigeration unit 11 being arranged in laboratory 10, includes
Control circuit 1, sensible heat exchanger 2, breeze fan 3, exhaust fan 4, air-supply passage 5 and air exhaust passage 6, the air-supply passage 5
For being connected to the air outlet in laboratory, the air exhaust passage 6 is used to be connected to the exhaust outlet in laboratory, the control circuit 1
It is respectively connected to breeze fan 3 and exhaust fan 4, the air outside laboratory passes sequentially through breeze fan 3, sensible heat exchanger 2
It is inputted with air-supply passage 5 to laboratory, the air of the laboratory internal passes sequentially through air exhaust passage 6,2 and of sensible heat exchanger
Exhaust fan 4 is exported to outside laboratory.
By taking southern environment as an example, open-air humidity is higher, and circumstance temperature is in 35/24 degree Celsius of air, is about contained
14g/m3The demand that humidity is kept in laboratory can be realized by the vapor in environment for the vapor of/kg.
Specific workflow is：Outdoor fresh air air is sent into sensible heat exchanger 2 by breeze fan 3, and fresh air air passes through
After sensible heat exchanger 2 cools down, the air outlet by air-supply passage 5 and laboratory enters laboratory internal.Fresh air air enters
It is humidified after laboratory internal for laboratory, and original low temperature dry air is by the effect of exhaust fan 4 in laboratory, successively
It is extracted to by exhaust outlet, air exhaust passage 6 in sensible heat exchanger 2, low temperature dry air is empty with fresh air in sensible heat exchanger 2
Gas exchanges heat, and absorbs in fresh air air and is rejected to after heat by exhaust fan 4 outside laboratory；Due in sensible heat exchanger 2
Portion only carries out heat exchange, does not reduce the humidity in fresh air air, therefore the humidity that fresh air air is brought can enter laboratory
Inside humidifies inner air, so as to ensure the constant humidity in laboratory.
With reference to Fig. 2, preferred embodiment is further used as, further includes the first humiture being arranged in laboratory 10
