Claims

[Scope of utility model registration request]

a compressor, a condenser, an expansion valve, an evaporator, a refrigerant pipe that sequentially connects these in an annular manner, a refrigerant pressure sensing device connected to a pressure sensing hole of the refrigerant pipe to sense refrigerant pressure; The pressure sensing device is equipped with a pressure propagation small diameter pipe for propagating the refrigerant pressure inside the pipe, and a collar portion and a protrusion protruding in the extension direction of the small diameter pipe are formed at the connecting end of the small diameter pipe with the refrigerant pipe. An air conditioner characterized in that the protrusion is inserted into the pressure detection hole, and the collar is welded around the pressure detection hole.
