Type III — Low-Pressure第 188 / 240 题
Low-loss fittings on recovery hoses are important on low-pressure work because they:
a.Increase system pressure
b.Speed up the compressor
c.Cool the refrigerant
d.Minimize refrigerant released when connecting and disconnecting
解析
Low-loss fittings seal automatically to release as little refrigerant as possible each time hoses are connected or disconnected. This reduces emissions and conserves refrigerant on every job. They are good practice on all recovery work, not only low-pressure.
