Abstract

The present invention provides a refrigerating cycle apparatus capable of simplifying the support structure of the refrigerant pipe and improving durability and manufacturability in addition to improving corrosion resistance. The air conditioner of the refrigerating cycle device includes a compressor, an outdoor heat exchanger, a throttle mechanism, an indoor heat exchanger, a refrigerant pipe that connects the compressor, the outdoor heat exchanger, the throttle mechanism, and the indoor heat exchanger to circulate the refrigerant pipe, a joint portion for connecting the compressor, the outdoor heat exchanger, the throttle mechanism and the indoor heat exchanger to the refrigerant pipe, and an outdoor unit housing for accommodating the compressor, the outdoor heat exchanger, and the throttle mechanism. A material having an equivalent ionization tendency or a material having a higher ionization tendency than the material of the outdoor unit frame is used for the joint portion and the refrigerant piping of at least a part of the joint portion and the refrigerant pipe.

Description

technical field [0001] Embodiments of the present invention relate to a refrigeration cycle device. Background technique [0002] As an example of a refrigeration cycle device, there is known an air conditioner that can perform cooling operation and heating operation by switching a four-way valve, and is equipped with a condenser that operates as a condenser during cooling operation and a condenser during heating operation. An outdoor heat exchanger that operates as an evaporator; and an outdoor unit frame that accommodates the outdoor heat exchanger. In conventional air conditioners, copper refrigerant piping has been used, but in the air conditioner described in Patent Document 1, aluminum or an aluminum alloy is used for a part or all of the refrigerant piping in the outdoor unit casing, and for The corrosion resistance of the outdoor unit is improved by using a Zn-Al-plated steel plate or a Zn-Al-Mg plated steel plate for the bottom plate of the outdoor unit frame.
