当室内温度高于预设温度上限时，控制器检测室外温度低于室内温度且低于相变材料的结晶点温度，机组启动；自控风量调节阀同时开启控制新风段和蓄能段，根据设定的逻辑控制两段风量的比例，排风机启动排风，室外空气经机组部分与相变材料进行能量交换(相变材料液体变为固体)后进入室内，部分直接进入室内对室内空气进行降温。When the indoor temperature is higher than the preset temperature upper limit, the controller detects that the outdoor temperature is lower than the indoor temperature and lower than the crystallization point temperature of the phase change material, and the unit starts; The proportion of the two-stage air volume is controlled by a certain logic, the exhaust fan starts to exhaust, the outdoor air enters the room after the energy exchange between the unit part and the phase change material (phase change material liquid becomes solid), and part of it directly enters the room to cool down the indoor air .
当室内温度高于预设温度上限时，控制器检测室外温度高于室内温度，机组启动；关闭进口段的新风阀，利用自垂式百叶的原理控制室内回风的引入，排风机停止，室内空气经机组于相变材料进行能量交换(相变材料固体变为液体)后对室内空气进行降温。When the indoor temperature is higher than the preset temperature upper limit, the controller detects that the outdoor temperature is higher than the indoor temperature, and the unit starts; close the fresh air valve at the inlet section, use the principle of the vertical louver to control the introduction of indoor return air, the exhaust fan stops, and the indoor After the air passes through the unit for energy exchange with the phase change material (the phase change material changes from solid to liquid), the indoor air is cooled.
当室内温度高于预设温度上限时，控制器检测机组送风温度和室外温度均高于预设温度上限时，立即关闭系统并启动原有空调工作。When the indoor temperature is higher than the preset temperature upper limit, the controller detects that the air supply temperature of the unit and the outdoor temperature are both higher than the preset temperature upper limit, and immediately shuts down the system and starts the original air conditioner.
当室外湿度高于室内预设的基准湿度，且室内温度高于预设温度上限时，关闭系统并启动空调降温除湿。When the outdoor humidity is higher than the indoor preset reference humidity and the indoor temperature is higher than the preset temperature upper limit, the system is turned off and the air conditioner is turned on to cool down and dehumidify.
