Résumé

Based on the climate characteristics of the Yangtze River in China and the disadvantages of radiation air conditioning, an energy-saving and temperature-controlled fresh air dehumidifier of radiation air conditioning was designed to remove fresh air load and latent heat load, which would enhance the indoor thermal comfort and energy efficiency combined with radiation air conditioning system. To meet the dehumidification and temperature control demand of fresh air in different seasons, three operating control modes were presented. The running performance and dehumidification performance in summer and transition seasons of the design dehumidifier was tested in standard enthalpy difference laboratory. With the change of outdoor dry bulb temperature, the suction and exhaust pressure and temperature of compressor, the dry-bulb temperature and wet-bulb temperature in indoor side, the moisture content in indoor and outdoor side, the unit's dehumidification capacity were tested. Results showed that in summer the dehumidification capacity ranged from 1.34 kg/h to 2.23 kg/h while in transition season, under the dehumidifying it was 2.19 kg/h to 10.2 kg/h for model A, and 0.37 kg/h to 0.9 kg/h for model B, which meet the dehumidification requirements of general residential building with radiation air conditioning.
