Installation principles of air conditioning refrigerant pipe

时间:2021-11-29浏览次数:367

I believe that the little companion who has a certain understanding of central air conditioning also knows that the installation of central air conditioning is synchronized with water and electricity, and it is installed in the ceiling, which belongs to shadow engineering, so the installation is very important! As the "transportation hub" of "escort" refrigerant, refrigerant pipeline is very exquisite in installation! Follow Xiaobian to see if your master has achieved the following "three inconsistencies and one timeliness" criterion when installing!

I. timely: seal and maintain the refrigerant pipe in time after cutting

The refrigerant pipeline installation of central air-conditioning is synchronized with water and electricity. After the indoor unit installation is completed, the refrigerant pipeline installation is one of the most important links in the process of central air-conditioning installation. However, in the process of construction, the refrigerant pipe will experience cutting, welding, nitrogen filling maintenance, pressure testing and other processing methods. If the refrigerant pipe is too thin, it is easy to cause cracking, resulting in refrigerant leakage. In Dajin's fortification specification, the wall thickness of the refrigerant pipe is required to be no less than 0.8mm to ensure that the refrigerant pipe can be within a reasonable thickness after processing.

In the process of processing the refrigerant pipe, it should be noted that the sealing maintenance needs to be done in time after the cutting of the refrigerant pipe, because a lot of dust and impurities will be generated during the decoration. If the split maintenance is not done well, these dust impurities on the construction site can easily enter the refrigerant pipe, and even enter the compressor with the refrigerant, affecting the service life of the air conditioner.

I. No: refrigerant pipes and drainage pipes cannot be fixed by sharing hoops

When the refrigerant pipe and drain pipe are laid, you need to pay attention to whether your installation master can share the hoop. The correct way is to fix the refrigerant pipe and drain pipe with hoops respectively, and the position of the hoop should be on the same line as far as possible to ensure that there is a suitable spacing between the refrigerant pipe and drain pipe. If the sharing of hoops will cause the air conditioner to form a certain vibration to the refrigerant pipe and drain pipe during operation, the pipe will have a certain displacement after a long time, which will more or less affect the effect of the air conditioner.
II. No: the insulation material of refrigerant pipe cannot be extruded

The operation condition of refrigerant directly affects the application effect, and the insulation of refrigerant pipe cannot be ignored. The thermal insulation cotton used in Dajin central air conditioning unit is marked with the words "specially for Dajin air conditioning unit". The thermal insulation material used is rubber and plastic, and the fire rating can reach the fire-resistant B1 level.

Materials and devices can directly affect the application effect of air conditioning, so in addition to choosing the insulation cotton with the words "specially for Daikin Air conditioning devices", you should also pay attention to whether the hoop width used on the insulation material outside your refrigerant pipe is enough. If it is too narrow, it is easy to cause the insulation cotton to be squeezed and deformed by the hoop, thereby reducing the insulation effect; And don't wrap the insulation cotton with tape, otherwise it is easy to cause the air to be squeezed out and affect the insulation effect.

Three no: the refrigerant pipe cannot be exposed

When installing the refrigerant pipeline, it is necessary to have insulation cotton to cover it up, but it is necessary to pay attention to whether the installation master has made the insulation cotton splice intact. Do not have exposed parts of copper pipes at the insulation cotton splice, otherwise the insulation effect will be affected.
