Temperature is able to maintain that one is suitable within the temperature range of sterilization, effectively to kill the bacterium in evaporator 2.
Step S104 judges whether that the scheduled second time period of heating operation or air-conditioning enter load guard mode, such as
Fruit is to execute step S105.
During controlling 2 heating operation of evaporator, controller 1 also judges evaporator 2, and whether heating operation is pre-
Whether fixed second time period or air-conditioning enters load guard mode, if evaporator 2 is that heating operation is scheduled
Second time period enters load guard mode, thens follow the steps S105.
Step S105 stops heating operation.
When evaporator 2 is the scheduled second time period of heating operation or to have entered load guard mode, control
Device 1 sends out stopping control signal to evaporator 2, and evaporator 2 stops heating operation after receiving stopping control signal, terminates whole
A cleaning process.
