4.2.24 Defrost control
When heating operation, defrost operation is conducted to melt frost on outdoor unit heat
exchanger.
[Defrost starting condition]
Intelligent type
Defrosting starts when the following conditions have been realized.
Defrost condition
Defrost upper limit time A
When Outdoor temperature>–5 ˚C, A = 3 hours
When Outdoor temperature
≤
–5 ˚C, A = 6 hours
Heating integral capacity
Integral compressor run time is 25 minutes or more from the completion of previous defrost operation.
Low pressure equivalent saturation temperature (Te) is within the defrost permitting area.
Outdoor unit heat exchanger temperature (Tb) is within the defrost permitting area.
Defrost upper limit time A is met.
Low pressure equivalent saturation temperature (Te) is within the defrost requesting area.
Outdoor unit heat exchanger temperature (Tb) is within the defrost requesting area.
Heating integral capacity is low.
