Benefits of technology

The present outdoor unit has a three-way valve placed between a switching unit and an oil separator to reduce damage to the refrigerant pipe and connection parts caused by compressor vibration. Additionally, when the compressor is detached and re-attached, the valve allows for vacuaging to prevent cost increase and improve maintainability.

Problems solved by technology

However, recovering the refrigerant from the refrigerant circuit is a time consuming process.
Thus, recovering the refrigerant from the refrigerant circuit is a time consuming process, resulting in poor maintainability of the air conditioner.

Embodiment Construction

[0012]In the following detailed description, for purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.

[0013]The air conditioner described in Patent Document 1 includes an open / close valve fitted to the discharge pipe. This air conditioner is more likely to cause the following disadvantages than other air conditioners where the open / close valve is not fined to the discharge pipe. Namely, when the driving of the compressor causes vibration in the discharge pipe, a huge force may be applied to the discharge pipe and to a connection part between the discharge pipe and other devices (such as the compressor or an oil separator) due to the weight of the open / close valve. As a result, the di...

Abstract

An air conditioner outdoor unit includes: a compressor; a heat source-side heat exchanger connected to the compressor; an oil separator disposed between a refrigerant discharge opening of the compressor and the heat source-side heat exchanger configured to separate a refrigerant oil from a refrigerant discharged from the compressor; and a first three-way valve fitted to a refrigerant pipe between the oil separator and the heat source-side heat exchange.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is based on Japanese Patent Application No. 2013-032900 filed with the Japan Patent Office on Feb. 22, 2013, the entire content of which is hereby incorporated by reference.BACKGROUND[0002]1. Technical Field[0003]The present disclosure relates to an air conditioner having an outdoor unit and an indoor unit, which are connected to each other through a plurality of refrigerant pipes.[0004]2. Related Art[0005]Conventionally, there is known an air conditioner having an outdoor unit and an indoor unit connected in parallel through a plurality of refrigerant pipes. In this air conditioner, a refrigerant circuit includes devices that are connected to refrigerant pipes by welding, and the refrigerant pipes themselves are also connected together by welding, and the refrigerant pipes are also connected to each other by welding. The refrigerant circuit is filled with a refrigerant.[0006]The refrigerant circuit is connected to a compr...
