Abstract

The invention discloses a pipe line of a multiple air conditioner group, comprising an air pipe, a liquid pipe, an oil pipe and a balance pipe communicated with every outer low pressure side, the special communicated location is every outer air-liquid separator. The balance pipe is arranged in the magnetic valve located at the main device side of the multiple air conditioner groups. The magnetic valve is started when the multiple air conditioner groups is producing heat and is shut down in the heat producing oil modification process. The balance pipe is arranged with a single direction valve arranged at the child device side of the multiple air conditioner groups, the cooling liquid could only be flow out from the child device. The balance pipe is arranged with balance pipe cutoff valve arranged on the balance pipe at the main device side and every child device side of the multiple air conditioner groups. The problem that the device is hard to start or being damage caused by the accumulation of the cooling liquid when the multiple air conditioner groups are producing heat and the child device is shut down could be avoided.
