Anti-freezing and anti-condensing device and method for climatic environmental chamber

Abstract

The invention relates to an anti-freezing and anti-condensing device and method for an climatic environmental chamber, and relates to the technical field of environmental test. The anti-freezing and anti-condensing device and method is creatively adopted in a terrace of the climatic environmental chamber and have the advantages that the device is simple but reliable in structure, can be used in most climatic environmental chambers, and is lower in cost and relatively good in feasibility; when a low-temperature test is carried out, a vent pipe fan is started along with the start of the test, sothat the temperature of the terrace can be adjusted, and relatively good operability is achieved; and the design structure is simple, the operation is easy, the implementation is easy, the environmental test efficiency can be effectively improved, and good economic benefits and popularization values are achieved.

Description

technical field [0001] The invention relates to the technical field of environmental testing, in particular to an anti-freezing and anti-condensation device and method for a climate environment chamber. Background technique [0002] The climate environment cabin refers to the cabin used for the environmental simulation test of vehicles or equipment. The field working conditions of civilian or military vehicles or equipment are harsh and the climate is changeable. Reliability under environmental conditions requires environmental simulation tests on vehicles or equipment. [0003] At present, the common environmental simulation tests are divided into indoor tests and field tests. According to the types of environmental factors that can be simulated, the simulation environment cabin can be divided into: low temperature environment cabin, high temperature and humidity environment cabin, solar radiation environment cabin, or comprehensive simulation environment cabin with low te...

Problems solved by technology

Common floor structures are usually in the form of cement layer, thermal insulation layer, and cement layer. Due to the high specific heat of cement and its ventilation characteristics, if the low temperature test is followed by a damp heat test, the temperature rise of the floor lags behind that of the air. The temperature will cause a large amount of condensation on the floor, and the condensation will penetrate into the cement layer of the floor. During the low temperature test, the expansion of the condensation will cause damage to the insulation layer of the floor
