Multi-compartment environmental chamber

Abstract

The invention discloses a multi-space environmental chamber, and belongs to the technical field of environmental detection instruments. The multi-space environmental chamber is characterized by comprising an environmental chamber body and an air treatment device; the air treatment device is used for detecting environmental chambers, and an environmental chamber heat-insulation tank and a distribution metering device are arranged in the environmental chamber body; the environmental chamber heat-insulation tank is provided with a plurality of test environmental chambers which are arrayed in a matrix manner, and air channels are formed among the adjacent test environmental chambers; the test environmental chambers are connected with the distribution metering device outside the environmental chamber heat-insulation tank by a preheating pipeline; a hot air system is further arranged at the bottom of the environmental chamber heat-insulation tank, and the internal environmental temperatures of the environmental chamber heat-insulation tank can be guaranteed by the hot air system; the air treatment device for detecting the environmental chambers is connected with the distribution metering device by pipelines. The multi-space environmental chamber has the advantages that the multi-space environmental chamber is simple in integral structure, detection operation can be simplified, all the detection environmental chambers are uniform in temperature, energy can be saved, and the running cost can be effectively lowered.

Description

[0001] Technical field: [0002] The invention relates to a multi-compartment environmental chamber, which belongs to the technical field of environmental detection instruments. [0003] Background technique: [0004] In the prior art, when the environmental chamber used to detect the amount of harmful gas released by materials is working, the sample of the tested material placed inside it will release harmful gas, and at the same time, the treated clean air with constant temperature and humidity must be ventilated according to regulations. Slowly inject a large amount of air into the environmental chamber, and while the harmful gas and clean air are fully mixed, the mixed air with the same flow rate as the injected air will slowly be discharged out of the chamber through the exhaust hole. After the time specified in the standard (usually 24 hours), the concentration of harmful gases in the environmental cabin reaches equilibrium, and the inspectors can sample the air in the ca...

Problems solved by technology

[0007] The disadvantages of the above-mentioned utility model: 1) The layout of multiple environmental chambers cannot be disclosed in the environmental chamber module, and the temperature and flow uniformity of the air flowing through the inner and outer surfaces of the environmental chamber cannot be solved. When the number of environmental chambers is large (for example 9), can cause the temperature in the interior tank of some environmental chambers to be inconsistent with the set temperature; 2) in the aerodynamic module (equivalent to the clean air source of the present invention), the water washing device is arranged in front of the cold-drying dehumidification device, resulting in water temperature Too high, the effect of removing water-soluble harmful gases is not ideal (like carbon dioxide is easily soluble in frozen beer, gas is more easily dissolved in low-temperature water)

This heating method has a large heat loss and uneven temperature. When the number of environmental chambers is large (for example, 9), it is easy to cause the temperature of the upper environmental chamber to be high
