With the development of the automobile manufacture level in our country, it’s necessary to carry out the tests for whole vehicle or parts. At present, in China, only a few venues can provide the conditions for automotive testing, and all the test sites are at normal temperature. Therefore, the construction of low-temperature environment test site has become imminent. According to the survey, Heihe and Bei’an of Heilongjiang in China have established low-temperature test site spontaneously, but the test site are based on business requirements for each test, and there are no unified planning. So, how to build a rational, scientific, economic low-temperature test site, has become the focus of our research.
