Construction management strategies for heating, ventilation and air conditioning projects (1)

1. Material selection and strict quality control

During the operation of the air conditioner, there are high quality requirements for the internal water circulation of the air conditioner. This is also a link that is more likely to cause problems during the installation process. If the internal water circulation is not established and the water cannot be discharged normally, it will affect the normal operation of the entire equipment. Therefore, the quality requirements for pipeline materials are relatively high, and the construction unit must pay full attention to material selection and arrange dedicated personnel to strictly control the quality of pipe materials. The construction unit must conduct on-site inspections of material suppliers, select manufacturers that meet relevant requirements, and sign material supply contracts to ensure the quality of construction materials from the source. When the pipeline materials are delivered to the construction site, they must be inspected. Before construction, a secondary inspection is required. Only if both inspections are qualified can the materials be used in the construction process. It is necessary to choose a suitable place to store all construction materials, store them according to the type and characteristics of the materials, and arrange personnel to protect the pipeline materials to prevent the materials from being eroded by rain or corrosion, and ensure the quality of the construction materials.

2. Strengthen equipment management

Equipment factors are an important factor in the installation and construction of heating, ventilation and air conditioning projects. There is an inevitable connection between the quality of HVAC equipment and the quality of project construction. Therefore, in order to create high-quality projects, managers need to implement equipment management and comprehensively eliminate equipment risks. , which is also an effective measure to improve the installation and construction quality of heating, ventilation and air-conditioning projects. After the HVAC equipment is brought in, it cannot be put into use directly and needs to be systematically inspected. Some equipment may be damaged in appearance and parts may fall off due to the bumps of the vehicle during transportation. Therefore, managers must check the appearance of the equipment in detail. If you find defects in the appearance of the equipment or parts falling off, you must contact the manufacturer promptly and return the equipment to the factory. In addition, after the appearance inspection, the performance of the equipment must be debugged to ensure the functional integrity of the HVAC equipment. In this way, the quality of installation and construction of heating, ventilation and air conditioning projects can be improved.

3. Pay attention to details

In the process of making and installing air ducts for heating and ventilation, the production and installation of air ducts is the basic work. The pipe sealing production process of many construction units is relatively mechanized. Mechanical equipment is usually used to process the air ducts, and then the details are processed by hand. . Before making the air ducts, professionals will design the air ducts. During the design process, the installer must consider the intersection between electrical equipment and drainage pipes, and choose the most appropriate design plan based on the actual construction conditions. After professionals design the drawings, they must immediately communicate with the construction personnel to further discuss the design content. Projects such as supports, hangers, flanges, etc. can be carried out simultaneously with the production of air ducts. The main purpose of hoisting the air duct is when the air duct is 10m to 20m away from the ground. You need to use manual or electric hoists, channel steel, etc. to raise the height. Use hoisting to fix the air duct. In addition, prepare a lift for emergencies. During the installation process, if the air duct needs to pass through the wall or floor, you can use thin steel plates for welding. When it is 200mm away from the wall or floor, use fireproof materials to bundle and fix it to ensure that the air duct can be used safely.
