Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
The utility model provides a kind of combined high low temperature low air pressure testing chamber as Figure 1-4, including casing 1, refrigeration system
System 5, electric control cabinet 4, chamber use monolithic construction, and the top of the casing 1 is operating room 2, and the front end of operating room 2 is installed
There is sucked type sealing joint strip, the inside of casing 1 is provided with evaporator fixed mount 12, refrigeration evaporator is fixed with evaporator fixed mount 12
Device, bottom are vacuum system 3, and the refrigeration system 5 is located at the rear lower of operating room 2, and it is right that the electric control cabinet 4 is located at casing 1
Below.
Specifically, the front of the casing 1 is provided with gate 6, the both sides at gate 6 are provided with big door handle 7, gate 6
Top is provided with control operation door-plate 10, and bottom is provided with observation window 9, and the top of observation window 9 is provided with illuminating lamp 11 and USB

Specifically, the refrigeration system 5 includes refrigeration compressor, condenser and refrigerating evaporator.
Specifically, the vacuum system 3 includes vavuum pump, vacuum measurement system, high vacuum charge valve and high vacuum gear
Plate valve.
Pressure work principle：
Pressure reduction, central controller detect live signal from pressure element, compared with the pressure signal of setting, obtained
To comparison signal, opening for a position formula switching signal control vavuum pump valve and high vacuum pneumatic ball valve is exported by control instrument
Close, and the purpose for reaching automatic pressure control (uses dynamic pressure balance mode, realized by the unlatching of high vacuum pneumatic ball valve
Pressure behaviour balances)；Recover press process, when needing to recover pressure, then open cap of high-vacuum baffle valve, be filled with by gas-charging connection
Required gas.
Temperature operation principle：
Central control system is amplified, after analog/digital conversion, gamma correction according to the temperature inside the box signal collected
With the setting value of temperature（Desired value）It is compared, through PID arithmetic, output regulation signal automatically controls to be added the deviation signal drawn
The power output size of hot device, the heating in laboratory and heat leakage is reached a kind of dynamic equilibrium, be finally reached constant temperature purpose.
