Abstract:
1. An apparatus for converting a refrigerant pipe of an air conditioner comprising: a valve housing having a valve space portion therein, and composed of a first refrigerant inlet formed at one lower portion thereof and connecting the valve space portion and a refrigerant discharge pipe of a first compressor, a second refrigerant inlet formed at another lower portion thereof and connecting the valve space portion and a refrigerant discharge pipe of a second compressor, a refrigerant outlet formed at one upper portion thereof and connected to a refrigerant circulation pipe of a condenser, a bypass outlet formed at another upper portion thereof and connected to the refrigerant circulation pipe of the condenser, and a detour refrigerant inlet formed at a side of the first refrigerant inlet and connecting the valve space portion to the first refrigerant inlet; a bypass pipe for connecting the bypass outlet of the valve housing to a refrigerant circulation pipe connected to refrigerant suction pipes of the first and second compressors; an open/close valve slidably installed in the valve space portion of the valve housing so that a refrigerant introduced into the valve space portion of the valve housing can be selectively introduced into the refrigerant circulation pipe of the condenser or the bypass pipe; and an open/close valve driving means installed at both sides of the open/close valve and driving the open/close valve.
