A NEW HOUSEHOLD CENTRAL AIR-CONDITIONING OF TEMPERATURE HUMIDITY INDEPENDENT CONTROL

The indoor temperature and humidity could be adjusted and controlled independently in the temperature humidity independent control air conditioning. However, there isn't a small size household air conditioner that can supply two working fluids of different temperatures simultaneously, which can realize the application of temperature humidity independent control in residential buildings. In this paper, a new kind of household central air-conditioning of temperature humidity independent control was proposed. The key technology is the household temperature humidity independent control air conditioner. It has two evaporators, and makes use of the inverter compressor and electric expansion valve. In order to validate the operating performance of this air conditioning, we designed two sets of sample housings with different terminal equipments in different cities. hi the mean while the field test was made in summer and winter separately and the operating performance running at variable conditions was researched. Partial test results were displayed in this paper, and it showed that the precise control on temperature and humidity in separated room could be realized, improving the thermal comfort. Therefore, this kind of household central air-conditioning should be promoted, especially in hot and humidity climates.
