主要特點：

◆采用分體式結構，將壓縮機、風扇、冷凝器等置于室外，使室內機組結構緊湊、噪音低；

◆合理的水循環使換熱器換熱效率高，堅固耐用、不易阻塞、抗凍能力強；

◆采用蓄冷動態平衡連續工作方式，因而大大減小了室內機組貯水箱的體積，只需有60升水就可滿足工作要求，且溫度控制準確、穩定；

◆操作十分簡便，只需按啟動開關，機組即進入工作狀態；

◆采用溫控節點控制自動加熱系統，保證北方地區冬季能正常使用；

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.
