Abstract
A gas-side stop valve on the gas refrigerant side and a liquid-side stop valve on the liquid refrigerant side are provided in a package of an outdoor unit. A gas-side filter on the gas refrigerant side is mounted on the indoor unit side relative to the gas-side stop valve and inside the package of the outdoor unit. A liquid-side filter 9 on the liquid refrigerant side is mounted on the indoor unit side relative to the liquid-side stop valve and inside the package of the outdoor unit. As a result, it is not necessary to ensure a place for mounting the gas-side filter and the liquid-side filter at the time of installation on site and the workability can be improved.
