2) The chiller-heater starts dilute operation after stopping operation and the solution pump and
refrigerant pump runs continuously.
3) When the solution temperature of the high pressure generator drops below 110
℃
, the refrigerant
pump stops.
4) After about 20 minutes of stopping operation, the solution pump stops and the dilute operation is
completed.
