主要特点：

◆采用分体式结构，将压缩机、风扇、冷凝器等置于室外，使室内机组结构紧凑、噪音低；

◆合理的水循环使换热器换热效率高，坚固耐用、不易阻塞、抗冻能力强；

◆采用蓄冷动态平衡连续工作方式，因而大大减小了室内机组贮水箱的体积，只需有60升水就可满足工作要求，且温度控制准确、稳定；

◆操作十分简便，只需按启动开关，机组即进入工作状态；

◆采用温控节点控制自动加热系统，保证北方地区冬季能正常使用；

The structure of SL401 has separation design with compressor， fans， condenser installed outdoors， hence the indoors unit has compact conformation and low noise;

The heat exchanger of this product has well designed water circulation device which increases head exchange efficiency. It has strong robustness， less blocking， and good freezeproofing ability;

This product works on continuously running duty with dynamically balanced cold accumulation， and hence has greatly reduced water storage tank in the indoors unit. Only 60 liters of water is needed to meet the basic work request， and the temperature control is accurate and steady;

The operation of this product is very convenient. Just press the start button， and it will enter work mode.

With the temperature-controlled nodal operation self-heating system， this product can be used in the winter season of north China.
