Taboos for installing air conditioning and refrigeration pipes

Air-conditioning refrigeration pipes are used as auxiliary equipment in air-conditioning installation, but their importance cannot be ignored. If all relevant components have been installed successfully when the air conditioner is installed, and there are related problems with the installation of the refrigeration pipe, it will still cause problems in the use of the air conditioner and reduce the use effect of the air conditioner. So, how to install air conditioning and refrigeration pipes, and what problems should be paid attention to in the installation? Below, the editor will take you to understand the relevant matters that should be paid attention to in the installation of air conditioning refrigeration pipes.

　　 Taboo for installation of air conditioning and refrigeration pipes: the refrigeration pipes are not cleaned or dried before installation

　　 The refrigeration piping is not cleaned and dried before installation. In addition to increasing the amount of blown dirt after the system is installed, it will also affect the normal operation of the system. This causes problems such as wear of the refrigeration compressor cylinder and partial blockage of the system.

　　 The reason why the refrigeration pipes were not cleaned and dried before installation was because the construction personnel did not comply with the construction quality acceptance specifications and the technical standards for refrigeration pipe installation. The correct way is to remove rust, clean and dry the inner wall of the refrigeration pipe before installation, so that the pipe can be equipped with the conditions for system test operation after installation. There are many methods for rust removal of pipelines. In actual rust removal methods, different rust removal methods are used for rust removal according to the characteristics of the refrigeration system and the pipes of different materials.

　　 Taboo for installation of air conditioning and refrigeration pipes: the bending radius of the steel pipe and the three-way interface do not meet the requirements

　　The bending radius of the refrigeration steel pipe and the three-way interface do not meet the requirements, which will increase the resistance of the system and reduce the refrigeration effect of the refrigeration system.

　　The reason why the bending radius of the steel pipe and the three-way interface do not meet the requirements is that the construction personnel still carry out the installation design according to the general pipeline construction process, and the construction management has not formulated the refrigeration pipeline technical measures or the corresponding installation process standards.

　　 The bends and tees of refrigeration pipes shall meet the following requirements:

　　1. The refrigeration pipe should be bent as far as possible to use cold simmering to prevent the production of oxide scale or sand embedded on the pipe wall from increasing the dirt in the system due to hot simmering. The radius of curvature of the bend is equal to or greater than 3.5 of the pipe diameter.

　　 2. Welded elbows and pressed elbows cannot be used for refrigeration piping.

　　3. For the three-way connection of the refrigeration pipe, a "T"-shaped three-way connection should not be used, and a smooth bend should be used.

　　 Taboo for installation of air conditioning and refrigeration pipes: The slope and aspect of the refrigeration pipe and refrigeration compression time do not meet the requirements

　　The slope and direction of the refrigeration pipeline and refrigeration compression time do not meet the requirements, which will make the refrigeration system unable to operate normally and even cause major accidents.

　　The reason why the slope and aspect of the refrigeration pipeline and refrigeration compression time do not meet the requirements is that the construction personnel did not seriously implement the construction quality acceptance specifications and the refrigeration pipeline construction process standards. The construction site should strengthen management and technical supervision.

　　 Taboo for installation of air-conditioning and refrigeration pipes: The laying methods of refrigeration pipes and refrigeration auxiliary equipment do not meet the requirements

　　 The laying methods of refrigeration piping and refrigeration auxiliary equipment do not meet the requirements, which will affect the normal operation of the refrigeration system and reduce the refrigeration capacity.

The reason why the laying methods of refrigeration pipes and refrigeration auxiliary equipment do not meet the requirements is that they are not familiar with the key data such as the elevation, slope, and slope of the pipes required by the construction drawings, which makes them inconsistent with the design drawings, such as not timely before the test operation Discovery and correction, the system will not operate normally.

Understanding the relevant precautions in the installation of air-conditioning and refrigeration pipes will help the construction personnel to pay attention to what will go wrong during the installation. In this way, the construction personnel will pay special attention to the construction and installation to ensure better construction quality. Bring better air-conditioning effect. In addition, in addition to the installation of air conditioning and refrigeration pipes, attention should also be paid to the installation of air conditioning and other related components, so as to ensure the better use of air conditioning.
