Description

Piping module mechanism, air conditioner outdoor unit and air conditioning system

Technical Field

The invention relates to the field of air conditioners, in particular to a piping module mechanism, an air conditioner outdoor unit and an air conditioning system.

Background

The existing outdoor unit of the air conditioner comprises a compressor, a low-pressure tank, a heat exchanger, an oil separator, a check valve, a filter, a multi-way valve, an electrical element, a capillary tube and other components, wherein the components are connected through a connecting pipeline.

The existing air conditioner outdoor machine tubing has at least the following problems:

firstly, the installation, maintenance and operation are difficult, the efficiency is low and the cost is high; the device mainly reflects that (1) the connecting pipelines are large in quantity and complicated in connection path staggering, the installation and maintenance processes need field operation, and time, labor and cost are wasted; (2) The vibration is generated in the operation process of the compressor, so that the pipelines can generate relative motion in the operation process and further generate vibration stress, when the vibration stress is large, the fatigue life of the pipelines is short, and the pipelines are easy to break or damage to other degrees, when the pipelines are installed and maintained, the vibration stress test is required to be carried out on the pipelines so as to reduce or eliminate the vibration stress of the pipelines and prolong the fatigue life of the pipelines, when the vibration stress test is carried out, the vibration strain foils are required to be arranged on the connecting pipelines, and because the connecting pipelines are large in quantity and the connecting paths are staggered and complex, the arrangement cost of the vibration strain foils is high and long, and unqualified pipelines are required to be checked and adjusted one by one according to the vibration stress analysis result, so that the time, labor and cost are wasted; (3) The vibration is generated in the running process of the compressor, the pipeline also vibrates along with the compressor, in order to reduce the vibration, the rubber blocks, the sheaths and other fixing and protecting connecting pipelines need to be additionally arranged on the outer side of the connecting pipelines one by one, the connecting pipelines are large in quantity and the connecting paths are staggered and complex, so that the problems of time and labor waste and cost are caused when the rubber blocks and the sheaths are additionally arranged on the pipelines one by one;

secondly, the piping occupies a large amount of space, so that the whole space occupied by the outdoor unit of the air conditioner is large; the main body is as follows: in consideration of the problems that the operable space during installation and adjacent pipelines which are too close to each other are damaged due to mutual friction caused by vibration generated by the operation of the compressor, in the process of installing the connecting pipelines on site, minimum space must be reserved among the compressor, the low-pressure tank and the heat exchanger and among the adjacent pipelines so as to extend welding guns or put coils and other components into the space during the welding process of the pipelines and avoid the problem of pipe friction, so that the pipe arrangement of the outdoor unit of the air conditioner occupies very large space, and further the whole outdoor unit of the air conditioner occupies large space;

thirdly, the running noise is high; the vibration is generated in the running process of the compressor, the pipelines also vibrate along with the compressor, the connecting pipelines are large in quantity and complicated in connection path staggering, although a part of noise can be reduced in a mode of fixing and protecting the connecting pipelines by additionally arranging rubber blocks, sheaths and the like on the outer sides of the connecting pipelines one by one, the noise is still very large;

fourth, the connecting pipeline is easy to corrode and age: the main body is as follows: the pipelines are all directly exposed in the external environment and are easy to corrode and age under the influence of weather;

in summary, the piping of the outdoor unit of the air conditioner at present has at least the problems of difficult installation, maintenance and operation, low efficiency, high cost, large occupied space, large operation noise and easy corrosion and aging of the connecting pipeline.
