Description

上記課題を解決するために、本発明は、 第1の冷媒および第1の冷凍機油を使用した第1の熱源側ユニットと第1の利用側ユニットを、第2の冷媒および第2の冷凍機油を使用した第2の熱源側ユニットと第2の利用側ユニットとに置き換える際に、既設の液接続配管とガス接続配管とを利用し、その際に前記既設の液接続配管及びガス接続配管の真空引きを要する冷凍サイクル装置において、
前記第2の熱源側ユニットと、前記第2の利用側ユニットとを前記既設の液接続配管とガス接続で接続すると共に、
前記液接続配管に、冷媒中の酸を捕捉する不純物捕捉材料を収納した捕捉容器と、前記捕捉容器をバイパスするバイパス配管とを備えた不純物捕捉装置を設置し、
前記バイパス配管は前記液接続配管と直列に設けられるとともに、前記捕捉容器は前記バイパス配管から分岐した流体導入出管によって前記バイパス配管と並列に設けられることにより、前記既設の液接続配管及びガス接続配管の真空引きを行う際に、水分又は空気が前記補足容器と前記バイパス配管とに分岐して流れるように構成されたことを特徴とする。
In order to solve the above problems, the present invention provides a first heat source side unit and a first usage side unit using a first refrigerant and a first refrigerating machine oil, a second refrigerant and a second refrigerating machine oil. When replacing the second heat source side unit and the second usage side unit using the existing liquid connection pipe and the gas connection pipe, the existing liquid connection pipe and the gas connection pipe In refrigeration cycle equipment that requires evacuation,
Said second heat source side unit, while connecting the second user side unit in the existing liquid connection pipe and the gas connection,
In the liquid connection pipe, an impurity trapping device including a trapping container containing an impurity trapping material that traps an acid in the refrigerant and a bypass pipe bypassing the trapping container is installed .
The bypass pipe is provided in series with the liquid connection pipe, and the capture container is provided in parallel with the bypass pipe by a fluid introduction / extraction pipe branched from the bypass pipe, whereby the existing liquid connection pipe and the gas connection are provided. When evacuating the piping, moisture or air branches and flows into the supplementary container and the bypass piping .
