The available constant temperature and humidity equipment of low atmospheric pressure that this embodiment provided, when the low pressure appears in the pressure-bearing test chamber 601, use heating/cooling device 8 with cold and hot fluid working medium heating or cooling to preset temperature, then drive pump 9 with cold and hot fluid working medium conveying into pipe network 7, pipe network 7 gives out heat to pressure-bearing test chamber 601 with the mode of heat radiation in pressure-bearing test chamber 601, because heat radiation does not need air current 5 as heat-conducting medium, consequently, even in low pressure environment, pipe network 7 still can be steadily to pressure-bearing test chamber 601 output heat, thereby guarantee the constancy of pressure-bearing test chamber 601 temperature.
Preferably, each cavity wall of the pressure-bearing test cavity 601 is provided with the conduit pipe network 7, and the conduit pipe networks 7 on the cavity walls are communicated with each other.
Specifically, the pipe network 7 is arranged on each cavity wall, so that the uniformity of a temperature field in the pressure-bearing test cavity 601 can be improved, and the temperature at each position in the pressure-bearing test cavity 601 is basically the same.
In this embodiment, the pressure-bearing thermal insulation box includes a box main body 602 with an opening structure on one side and a box door 603 hinged to the opening of the box main body 602. One end of the pipe network 7 fixed at the box door 603 near the hinge is communicated with one end of the pipe network 7 fixed at the box main body 602 near the hinge through a hose 16.

Specifically, the heat preservation cotton 606 can play a heat preservation role, and the temperature stability of the pressure-bearing test cavity 601 is further improved.
In this embodiment, a fan 4, a heater 3 and an evaporator 2 are further disposed in the pressure-bearing test chamber 601.
Specifically, when the low-pressure test is not performed, the conventional constant temperature test can be conveniently performed by providing the fan 4, the heater 3, the evaporator 2, and the like, that is, the evaporator 2 and the heater 3 work in cooperation to keep the temperature in the cabinet constant, and the fan 4 is mainly used to accelerate the flow speed of the air flow 5 in the cabinet, so that the temperature in each part of the cabinet becomes uniform.
Optionally, referring to fig. 2, the fan 4 is of a unidirectional air outlet structure, the heater 3 is located on an air inlet side of the fan 4, and the evaporator 2 is located on an air outlet side of the fan 4.

For example, when the fan 4 blows air downwards, the first heating unit 301 is operated, the second heating unit 302 is not operated, and the first heating unit 301, the fan 4 and the evaporator 2 can form a counterclockwise circulating airflow 5 in the pressure-bearing test chamber 601. Or, when the fan 4 blows air upwards, the first heating unit 301 does not work, the second heating unit 302 works, and the second heating unit 302, the fan 4 and the evaporator 2 can form a clockwise circulating airflow 5 in the pressure-bearing test chamber 601. Therefore, the clockwise and anticlockwise airflow 5 flowing can be realized by using the two-way air-out fan 4, the evaporator 2 and the two heating units, and compared with the existing scheme of adopting the two fans 4 and the two evaporators 2, the air-out fan has the advantages of simple structure and low cost.

The fan 4 is used for driving the airflow 5 in the pressure-bearing test chamber 601 to form an upper circulation 501 passing through the fan 4, the first evaporator 2 and the third heater 3 in sequence and a lower circulation 502 passing through the fan 4, the second evaporator 2 and the fourth heater 3 in sequence. Specifically, the uniformity of the temperature field in the pressure-bearing test chamber 601 can be enhanced by the double-circulation airflow 5 flowing mode, and the experiment effect is improved.

It can be understood that when the low pressure test is required, the electric valve 11 is opened and the vacuum pump 13 is started, and the air condensation drying device 12 is arranged in front of the vacuum pump 13 in order to prevent the vacuum pump 13 from being damaged because the air in the pressure-bearing test chamber 601 has certain humidity.
Optionally, the constant temperature and humidity equipment with available low air pressure further includes a humidifying pipe 14 with one end communicated with the pressure-bearing test chamber 601, and the other end of the humidifying pipe 14 is communicated with a humidifying system 15.
