Outdoor unit multi-defrost function

Improves comfort of defrosting operation

Defrosting in conventional models temporarily reverses the refrigerant cycle to use indoor heat to melt the frost, thus causing the indoor temperature to fall (reverse cycle defrost).
The “outdoor multi-defrost function”enables large-capacity casing models of 22 and 24 HP and multi outdoor units to use outdoor heat for heat exchange and interchange defrost operation while minimising indoor heat absorption and decreases in indoor temperature.

*Reverse cycle defrost may also take place to protect the product.
