Provided are a test apparatus for dust-exposing breath of animals and a test method thereof. The test apparatus includes a constant temperature and humidity test box internally provided with a test chamber and provided with a dust inlet connected to a dust conveying device. The test chamber separated into a cleaning area and an activity area, and a blowing device is arranged in the cleaning area. The test method includes following steps: step S1: a test animal is placed in the activity area; step S2: dust is introduced and the blowing device is turned on; step S3: a temperature and a humidity are adjusted; step S4: the test animal is taken out to weigh and step S5: steps S1 to S4 are repeated, blood of the test animal is drawn after days for biochemical index assay, and a test cycle is completed.

An apparatus for improving temperature conditions in an animal housing environment exposed to an electromagnetic wave includes a cooling pipe adhered to and disposed on an inner sidewall of an electromagnetic reverberation chamber to allow a coolant to flow therein and a watering system configured to supply the coolant to the cooling pipe, wherein the cooling pipe prevents an increase in internal temperature of the electromagnetic reverberation chamber.
