Document Type and Number:
Japanese Patent JP7244763
Kind Code:
B2
Abstract:
A heat exchange unit is provided with which, even if a flammable refrigerant is used, the likelihood of the refrigerant reaching an electric component unit is reduced. An outdoor unit (20) constitutes a portion of an air-conditioning apparatus (1), and is connected to an indoor unit (30) via a liquid-side refrigerant connection pipe (6) and a gas-side refrigerant connection pipe (5). The outdoor unit (20) includes an outdoor housing (50), an outdoor heat exchanger (23) disposed inside the outdoor housing (50) and in which a refrigerant flows, a liquid-side shutoff valve (29) connected to the liquid-side refrigerant connection pipe (6), a gas-side shutoff valve (28) connected to the gas-side refrigerant connection pipe (5), and an outdoor electric component unit (8) disposed inside the outdoor housing (50). The refrigerant is a flammable refrigerant containing at least 1,2-difluoroethylene. When the outdoor unit (20) is in its installed state, the lower end of the outdoor electric component unit (8) is positioned above the liquid-side shutoff valve (29) and the gas-side shutoff valve (28).
