Description
technical field [0001] The invention belongs to the technical field of aircraft climate environment tests, and in particular relates to a multi-working-condition aircraft climate environment test temperature adjustment control system. Background technique [0002] At present, the temperature range that the convex-shaped climate environment laboratory needs to achieve is +74°C~-55°C. Within the range of +74°C~-55°C, the process of temperature from high to low belongs to the cooling process. The holding stage after the target temperature requires cooling supply. For the convex-shaped climate environment laboratory, the cooling capacity required in the process of cooling down and maintaining low temperature comes from the huge volume of indoor air, ground and enclosure structures, test pieces, indoor heat sources and leakage cooling. The demand for cooling capacity depends on the test conditions. Different test conditions have different cooling capacity requirements. The cooli...
