【摘要】：为改善目前的调温除湿机组调节能力差,适用范围窄,无法实现对出风温度与湿度的双重连续调节等问题,本文提出一种温湿度独立控制型调温除湿空调机组。该系统可根据机组的进风含湿量来对两个蒸发器内的空气流量进行调节以便控制机组的出风湿度,另外根据机组的进风温度来调节两个冷凝器内的制冷剂流量以便控制机组的出风温度,进而达到机组出风温度和湿度连续独立控制的目的。 为了研究温湿度独立控制型调温除湿机组的除湿及调温能力,本文对该系统进行了结构设计,并建立了温湿度独立控制型调温除湿机组的稳态数学模型,运用VB编制了系统仿真软件。经验证该仿真软件准确度良好,计算精度符合仿真要求。 仿真计算结果表明：进风干球温度为27℃,相对湿度为60%时,通过低温蒸发器的风量在1100m3/h～3000m3/h之间变化,随着低温蒸发器风量增加,机组除湿量变大,调温除湿机除湿量的调节范围为2.4～9.4kg/h；当风量全部通过低温蒸发器,流过翅片管式冷凝器的制冷剂流量比例在20%～100%之间变化时,调温除湿机温度的调节范围为21.6～35.1℃。调温除湿机组温度和湿度可单独调节,且调节范围较宽,增强了调温除湿机组在不同场合工作的适应性。 此外,本文通过对热泵空调除霜方式的分析,探讨了各种除霜方式的优缺点,结合除湿机除霜特点,提出一种适合本系统的热气旁通加电加热辅助的除霜方法。
[Abstract]:In order to improve the problems of poor regulating ability and narrow applicable range of the current temperature regulating and dehumidifying unit, it is impossible to realize the dual continuous regulation of the temperature and humidity of the outlet air. In this paper, an independent temperature and humidity control type temperature and dehumidification air conditioning unit is put forward in this paper. The system can adjust the air flow rate in two evaporators according to the moisture content of the inlet air of the unit in order to control the air humidity of the unit. In addition, according to the inlet air temperature of the unit, the refrigerant flow rate in the two condensers is adjusted to control the outlet air temperature of the unit, and the continuous independent control of the air temperature and humidity of the unit is achieved. In order to study the dehumidification and temperature-regulating ability of the temperature and humidity independent control type temperature and dehumidifier, this paper designs the structure of the system, and establishes the steady state mathematical model of the temperature and humidity independent control type temperature and dehumidifier group. The system simulation software is programmed by VB. It is proved that the simulation software has good accuracy and the calculation accuracy meets the requirements of simulation. The simulation results show that when the inlet air drying ball temperature is 27 鈩，
