Problems in the construction of heating, ventilation and air conditioning engineering

In the overall construction process of HVAC technology, HVAC is the core part, coupled with the complexity of the system, the construction industry has high technical requirements, therefore, the construction technicians responsible for the construction must be in accordance with the requirements of the actual design specifications, and actively improve their own technical level, in order to better control the construction focus. Driven by the continuous development of China's economy and science and technology, the level of HVAC system construction technology has also been significantly improved. However, in reality, there are still individual construction companies in order to achieve greater economic benefits, not strictly implement on-site supervision, occasionally triggering a variety of illegal business problems, which requires the construction unit according to the actual needs and technological conditions, the development of a practical quality control system, in the entire construction process of the quality and personnel for strict, appropriate management, to improve the quality of the construction personnel to understand the importance of ensuring that the entire heating design in an orderly manner This will require the construction unit to develop a practical quality control system according to the actual needs and technical conditions.

1. Lax quality control of materials and equipment

At present, the heating, ventilation and air conditioning project has the following problems in equipment selection: improper selection of materials and equipment, resulting in construction quality does not meet the standards. Some construction companies in order to maximize profits, in the selection of materials and equipment, substandard or use substandard quality materials or equipment, affecting the overall quality of the project, the situation is serious and may cause the air conditioning system can not run normally.

2. Noise problem

In the building heating, ventilation and air conditioning system, the system may produce strong vibration phenomenon in operation, not only will the service life of the heating, ventilation and air conditioning system, the use of the reliability of a serious impact, but also on the daily life of the users of the building and the formation of daily life and life, restricting the good development of the heating and ventilation system, impede the effective operation of air conditioning system.

3. Incorrect positioning of equipment, pipeline cross phenomenon

In the heating, ventilation and air conditioning engineering construction process, due to the limitations of the actual construction environment, it is easy to appear on the design drawings of the equipment installation location and the actual position of deviation, incorrect positioning of equipment, pipelines between the equipment there is a cross-over situation, affecting the smooth installation of the equipment, and may even cause different degrees of vibration of the equipment in the use of the process, affecting the effect of use. In the process of installation of heating, ventilation and air conditioning for large buildings, the occurrence of pipeline cross phenomenon, to immediately suspend construction, pipeline adjustment, if the installation deviation is large, it is likely to cause the construction project can not be handed over on schedule, resulting in economic losses of the construction unit.
