Every 90 seconds, the room temperature difference

 

 

 

 

 

 

 

 

between temperature detected by Ta and Ts and the

 

 

 

 

varied room temperature value are calculated to obtain

 

 

 

 

the correction value of the frequency command and then

 

 

 

 

the present frequency command is corrected.

varied room temperature value are calculated to obtain

 

 

 

 

the correction value of the frequency command and then
