Claims

[Scope of utility model registration claim] During heating operation, the refrigerant released from the compressor is
After passing through the indoor heat exchanger and flowing into the constriction section from a predetermined direction and depressurized at a predetermined degree of constriction, the air passes through the outdoor heat exchanger and returns to the compressor, and during cooling operation, the cycle is reversed and flows into the constriction section. In a shared air conditioner for heating and cooling that supplies air in the opposite direction and reduces pressure by a degree of throttling different from that used during heating operation, the throttling section includes a casing disposed in the middle of a refrigerant pipe and a refrigerant passage, Depending on the flow direction of the refrigerant,
a slider housed in the casing so as to freely slide within the casing, and when the slider slides as the flow direction of the refrigerant is changed, a part of the casing A common air conditioner for heating and cooling, characterized in that the area of the slider that blocks the refrigerant passage changes, and the degree of aperture is switched.
