The variable water temperature control system that based on PID controller was studied to deal with dynamic space load and refrigerating capacity of SAAC.
The frame of the utility model is simple and reasonable and is occupied smaller space with the bash water device and the refrigerating device is fixed on the tray of inside of the outer casing.
本实用新型结构简单合理，由于洗浴用水装置和制冷装置均固定在外壳内的托盘上，占用空间小。
