Abstract: A. study on the design of a simple artificial temperature control chamber was conducted. The size of the chamber was 2. 4×2×2. 1m. The controllable temperature of the chamber was 3 to 25 C higher than the air temperature outside the chamber. K_t.the index of chamber temperature uneven-distribution,was±0. 023. The light intensity ranged from 5 to 30 LX. The pattern of air movement in the chamber was reasonable. The chamber was efficient and economical , and proved to be a good temperature control apparatus used for the study on animal environment.
