Claims

[Scope of utility model registration request]

A bypass circuit is formed for the refrigerant that passes through the expansion valve provided during defrosting operation in the refrigerant circuit provided between the indoor heat exchanger and the outdoor heat exchanger. An air conditioner characterized in that the bypass circuit is kept in communication until the refrigerant temperature rises again.
