Productive operation patterns
Partial load operation
Conditions
(1) Not in the capacity control
(The operating frequency does not droop to the minimum frequency by high pressure
control system protection)
(2) In all-room unit operation
(3) All non-operating room units motorized valve opening is minimum.
In case that the conditions (1) and [(2) or (3)] are met.
As the surplus refrigerant is treated with the receiver, opening EVG stagnates the
refrigerant condensed through the auxiliary heat exchanger. (Providing a motorized valve at
the downstream side of the auxiliary heat exchanger clears the heat resistant temperature
of the motorized valve.)
The entire system control (suction overheat) is conducted by the adjustment of the surplus
refrigerant amount in the receiver via EVL. BP motorized valve is exclusively used for the
distribution control, and EVU for SC control.
