一种恒温恒湿空调的控制模型及应用

A Controlling Model and Application of Const Temperature & Const Humidity Air-conditioner

恒温恒湿空调在调节过程中涉及到制冷与加热,去湿与加湿两大矛盾,其调节对象是四个水阀、三个风阀,控制环节复杂。如果处理不好,空调系统内部会因"冷热抵消"而浪费能量,外部因室外新风引入量不合理而导致额外的能量交换损失。只有妥善解决制冷与加热、去湿与加湿、合理的新风引入三大主要矛盾,才能产生较大的经济效益。

The adjusting processes of const temperature ＆ const humidity air-conditioner comes down to two antinomy of cooling ＆ heating and dehumidifying ＆ humidifying. The adjusting objects are four water valves end three wind valves. The control is very complex. If it does not been done well. the air-conditioner system will waste large energy, because the cooling load counteracts the heating load in the system and loses energy when the outside air replaces the department air. If the three problems of antinomy of cooling ＆ heating, dehumidifying ＆ humidifying and edhibiting appropriate flash air can be solved it will bring a large economic benefit.
