摘　　要：针对我国长江流域的气候特点以及辐射空调存在的弊端，研发了一种新风控温除湿机组，该机组主要承担室内新风负荷和潜热负荷，与辐射空调系统结合实现温湿度独立控制，从而实现室内舒适度并降低能耗。为满足不同季节新风温湿度变化时的控温除湿需求，提出了三种运行控制模式。在焓差实验室对该机组在夏季与过渡季节的运行性能与控温除湿性能进行了实验，测试了压缩机吸排气压力与温度、室内侧出风干湿球温度与含湿量及机组除湿量随室外环境干球温度的变化。实验结果表明，新风控温除湿机组夏季除湿量为1．34～2．23kg／h，过渡季节A除湿量为2．19～10．2kg/h，过渡季节B除湿量为0．37～0．9kg／h，满足一般居住建筑辐射空调房间全年除湿要求。Based on the climate characteristics of the Yangtze River in China and the disadvantages of radiation air conditioning, an en- ergy-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 com- pressor, the dry-bulb temperature and wet-bulb temperature in indoor side, the moisture content in indoor and outdoor side, the unit＇s de- humidification 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.
