Finished automobile testing room capable of testing high-and-low temperature, humidity and volatile organic compounds

Abstract

The invention discloses a finished automobile testing room capable of testing high-and-low temperature, humidity and volatile organic compounds. The finished automobile testing room comprises a testing box, a common circulation air channel, an evaporator, a heater, a circulation fan, a first circulation air channel and a second circulation air channel, wherein the common circulation air channel is communicated with the interior of the testing box; the evaporator, the heater and the circulation fan are arranged in the common circulation air channel; the first circulation air channel and the second circulation air channel are connected with one end of the common circulation air channel in parallel; the first circulation air channel and the common circulation air channel are connected with each other so as to form a high-and-low temperature and humidity testing circulation air channel; the second circulation air channel is internally provided with a first volatile organic compound and dust filter; the second circulation air channel and the common circulation air channel are connected with each other so as to form a volatile organic compound testing circulation air channel. The two major functions of high-and-low temperature and humidity testing and volatile organic compound testing can be integrated, and the purchase cost and the maintaining cost are reduced greatly for users.

Description

technical field [0001] The invention relates to an environmental test system, more specifically to a whole vehicle test room capable of testing high and low temperature, humidity and volatile organic compounds. technical background [0002] The traditional volatile organic compound test room cannot do high and low temperature and humidity tests, because the activated carbon in the filter device adsorbs volatile organic compounds. When doing high temperature tests, the volatile organic compounds adsorbed by the activated carbon will volatilize. Activated carbon will absorb water when tested with moisture and humidity, causing the filter to fail. Therefore, users need to purchase high and low temperature, humidity test chambers and volatile organic compound test chambers separately, and then use high and low temperature, humidity test chambers for testing when doing high and low temperature, humidity tests, and use volatile organic compounds when doing volatile organic compoun...
