%X 本文针对地下室高热高湿的环境特点，研制了变风量恒温恒湿空调机组，对样机进行了机组性能实验及模拟地下室热湿环境的机组运行实验。设计了一套智能化模拟负荷发生器，在给定热湿负荷情况下，研究机组热湿负荷独立处理能力与运行特性。结果表明：机组循环风机的变风量可以调节机组的显热与潜热处理能力，机组热湿独立处理能力较好，误差在5%左右，可以定潜热变显热和定显热变潜热运行，房间温湿度控制效果良好，温度波动±0.2 ℃，相对湿度波动±3%。<br>According to the characteristics of high temperature and humidity in a basement, a variable air volume (VAV), constant temperature 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 operation 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 temperature and humidity can be controlled very well with a temperature fluctuation ±0.2 ℃ and a relative humidity fluctuation ±3%
