  • Page 39 Common control A : Compressor ON/OFF control When the control temperature reaches the [set temperature –1.0˚C] or lower, the compressor is stopped. When the control temperature rises and becomes higher than the [set point temperature], the compressor runs again.
  • Page 40 In order to prevent this situation, the high pressure is controlled to be 2350kPa or lower by adjusting the opening of the suction modulating valve. • By condenser fan When the ambient temperature is low during the air-cooled operation, the condenser pressure (high pressure) will decrease.
  • Page 41 I : Capacity control In the chilled mode operation, adjusting cooling capacity makes the supply air temperature stable at the set point temperature (SP). The capacity control is executed by adjusting the opening of suction modulating valve (SMV) between 3 to 100 %.
  • Page 42 ※1 If the shortage of cooling water is caused in water-cooled operation, the condensing pressure will increase, thus activating the high pressure switch. In order to prevent this event, operate the condenser fan so that the condensing pressure will not increase in excess of a high-pressure (HPT) set point.
