摘　　要：为综合考虑温度和湿度的需求,本文提出一种具有升温和调温除湿功能的房间空调系统,并根据机组在空调和除湿模式下的系统运行性能,找到最佳的除湿模式和压缩机控制方案。结果表明:该机组可实现空调模式、升温除湿模式和调温除湿模式;调温除湿模式比升温除湿模式的出风温度低约7%,出风相对湿度低约27%;前者的除湿量约为后者的2.8倍,单位功率除湿量约为后者的2.6倍;当室外温度<18℃时,启用升温除湿模式,压缩机可采取变频调节方式;当18℃≤室外温度≤24℃时,启用调温除湿模式,压缩机可采用“容量调节+变频”方式。该系统可有效解决长江中下游地区的房间空调器除湿后送冷风的问题。To comprehensively consider temperature and humidity requirements,this paper proposed a room air conditioning system with adjustable temperature and dehumidification functions.Furthermore,the performance of the system in air conditioning and dehumidification modes were examined.The results indicated that the device can realize the air conditioning mode,dehumidification mode with rising temperature,and dehumidification mode with regulated temperature.In the dehumidification mode,under all test conditions,the outlet temperature of the dehumidification mode with regulated temperature was approximately 7%lower than that of the dehumidification mode with rising temperature,and the relative humidity of the outlet was approximately 27%lower.Furthermore,the former mode exhibited a dehumidification amount of approximately 2.8 times of that in the latter mode,and the unit power of dehumidification was approximately 2.6 times of that in the latter mode.Hence,dehumidification mode with rising temperature should be used when the outdoor temperature is lower than 18℃,and the compressor can be adjusted via variable frequency.Dehumidification mode with regulated temperature should be used when the outdoor temperature is between 18℃and 26℃,and the compressor can be controlled with the"capacity adjustment+variable frequency"method.The system can effectively solve the problem of lower supply air temperature owing to the dehumidification in the middle and lower reaches of the Yangtze River.
