Claims

[Scope of utility model registration request]

A refrigeration cycle circuit is constructed by connecting a compressor, an indoor heat exchanger, a pressure reducer, and an outdoor heat exchanger to a four-way valve with a slide valve inside the valve body through a refrigerant circulation path. In a heat pump type air conditioner that switches between cooling, heating, and defrosting by the sliding movement of a slide valve, the four-way valve is provided with a motor that drives the slide valve,
A heat pump type air conditioner characterized in that the motor adjusts the opening of the slide valve and performs a switching operation.
