背景技术 Background technique
现有技术的新风机组，其送风的温度和湿度会随着室外的新风的温度湿度变化而变化，因此，现有新风机组的送风温度和湿度难以控制。另外，由于现有新风机组容易对室内温度和湿度产生影响，从而使得新风机组送出的风会影响室内的舒适性。而且，由于室外新风的温度和湿度的变化范围大，当新风的温度和湿度偏离新风机组的设计工况时，新风机组的效率会降低甚至会影响新风机组的安全运行。 In the fresh air unit of the prior art, the temperature and humidity of the air supply will change with the temperature and humidity of the outdoor fresh air. Therefore, it is difficult to control the temperature and humidity of the air supply in the existing fresh air unit. In addition, since the existing fresh air unit easily affects indoor temperature and humidity, the wind sent by the fresh air unit will affect indoor comfort. Moreover, since the temperature and humidity of the outdoor fresh air vary widely, when the temperature and humidity of the fresh air deviate from the design conditions of the fresh air unit, the efficiency of the fresh air unit will decrease and even affect the safe operation of the fresh air unit.
