The first cooler 811 has a power of 500W and is used to control the temperature of the deaerated water coming out of the external circulation pump 510. Together with the 200W heater, it outputs deaerated water at a temperature suitable for the human body. The second cooler 812 has a power of 700W and is used to control the water temperature of the deaerated water coming out of the deaeration column 100 to a lower temperature, so as to facilitate the water supply circulation and output of water at a temperature suitable for the human body.

[0035] PID closed-loop temperature control is an automatic control technology that dynamically adjusts heating / cooling power through three stages: proportional, integral, and derivative, to achieve precise and stable temperature. The temperature regulation unit using PID closed-loop temperature control can better regulate the heating and cooling parts in a timely manner.

[0036] This application employs bidirectional temperature regulation through the above settings to achieve higher precision in zoned temperature control.
