Abstract
According to the characteristics of high temperature and humidity in a basement, a variable air volume ( VAV) , constant tem-perature and humidity unit was manufactured and investigated experimentally. Two sets of experiments were carried out on a prototype, namely, a unit performance test and an operation test, to simulate the thermal environment of a basement. An intelligent load simulator was designed to generate the required sensible and latent load, and the independent handling capacity to sensible and latent load and oper-ation characteristics of the unit were studied. The results show that the sensible heat and latent heat handling capacity of the unit can be regulated based on the variable air volume, and the heat and moisture can be processed almost independently with an error of about 5％. The unit can operate under fixed sensible heat and a change latent heat, or fixed latent heat and a change sensible heat. The room temper-ature and humidity can be controlled very well with a temperature fluctuation ± 0. 2 ℃ and a relative humidity fluctuation ± 3％.关键词
