Embodiment Construction

[0037] Please see figure 2 , is the pipeline diagram of the multi-connected air conditioner unit in the first embodiment of the present invention. The graph is in figure 1 Based on the improved pipeline, figure 2 neutralize figure 1 The same components use the same reference numerals, and will not be further described.

[0038] from the figure 2 It can be seen that with figure 1 Compared with this multi-connected air conditioner unit, in addition to pipelines such as oil equalizing pipes, gas pipes, and liquid pipes, the gas-liquid separator 1108 of the main machine and the gas-liquid separator 1208 of the slave machine are connected by pipelines. Known as the balance tube (thick line in the picture). The balance pipe is equipped with a solenoid valve 1110 at a pipeline position close to the gas-liquid separator 1108 on the main machine side. In addition, a balance pipe cut-off valve 1109 is installed on the side of the balance pipe host. On the slave machine side, ...

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.

Description

technical field [0001] The invention relates to air-conditioning technology, in particular to a pipeline device of a multi-connected air-conditioning unit. Background technique [0002] The multi-connected air conditioner unit is a single refrigeration cycle system composed of one or several outdoor units connected to several direct evaporative indoor units of different or the same type and capacity, which can directly provide one or several different areas with processed Air. The multi-connected air conditioner unit is a centralized, large-scale, and intelligent product of ordinary split air conditioners. Its main feature is the free combination of indoor and outdoor units and independent control. Its flexible, convenient, energy-saving and high-efficiency features have attracted more and more attention from the industry. . [0003] In the multi-connected air conditioner unit, each indoor unit is connected to the outdoor unit through complex pipelines to form a closed pip...
