    Modern climatic chambers for temperature and humidity simulations are operated over a wide range of environmental test conditions such as a temperature (-70 ℃ to 200 ℃) and a relative humidity (10% RH to 98%RH) for biological items and industrial products. The stability and fluctuation control of these thermal-environmental conditions are critical for the preservation of the test specimen and products. Even though climatic test chambers are found in many industries and companies, rare literature and data is found on the experimental investigation of the stability of these climatic test chambers. In this study, an experimental investigation on the possibility of minimizing fluctuations and ensuring stability, by the adoption of a variable speed compressor to the refrigerating unit of a 400-Liter temperature and humidity chamber is carried out. It is found that, adopting a variable speed compressor to the refrigeration unit has a significant potential to ensure stability of climatic chambers with an added advantage of energy savings for a given operating and surrounding conditions.
