Brief introduction of building code for ventilation and air conditioning

In hot summer, people like an electric appliance best, and that is air conditioning. How pleasant it is to spend a beautiful day in an air-conditioned room? ! ? However, with the temperature rising in recent years, ventilation and air conditioning have been widely used in more public places and some special jobs. The installation of tooling ventilation and air conditioning is also divided into indoor and outdoor work. Because many mechanical parts of ventilation and air conditioning are related to the smooth flow of our air, the installer must abide by our ventilation and air conditioning construction specifications when installing, and we must strictly follow this specification to ensure the safety and interests of both parties. Finally, let's look at the ventilation and air conditioning construction.

The main function of ventilation and air conditioning is to provide oxygen for people to breathe, dilute indoor pollutants or odors, eliminate pollutants generated by indoor technological processes, remove indoor residual heat or moisture, and provide air for indoor combustion. Mainly used in homes, businesses, hotels, schools and other buildings.

It is very different from our ordinary air conditioner. The requirements for air filtration are different. General air conditioning system adopts primary and secondary filtration, while ventilation and air conditioning must be equipped with tertiary and above filters; 2, indoor pressure control, the general air conditioning system has no obvious requirements for indoor pressure, and the clean air conditioning system has clear provisions for maintaining the pressure difference in the clean room; 3. In terms of air distribution, the general air conditioning system aims to improve the uniformity of indoor temperature and humidity field as much as possible with less ventilation, while the ventilation and air conditioning system must limit and reduce the diffusion of dust particles as much as possible to ensure the required cleanliness and make the dust particles quickly discharged outside; 4. In terms of air exchange? The ventilation and air conditioning system should reach at least 10 times /h, or even hundreds of times.

During the construction of ventilation and air conditioning engineering, we should pay attention to the coordination with professional engineering and equipment suppliers such as civil engineering, decoration engineering and electromechanical installation. For example, when cooperating with civil engineering to reserve embedded parts, attention should be paid to the shape, size and position of reserved holes and the position of embedded parts. And size, etc. Comprehensive layout of various pipelines and determination of construction sequence; Provide electrical data such as electrical parameters, control points and control requirements of equipment to electrical specialty in time; When installing the fan coil unit, the air outlet (including air supply, return air, fresh air inlet, etc.). ) and open the access door, pay attention to the right? Finished product protection of decoration engineering; Provide the equipment supplier with the arrival time, installation requirements and corresponding data in time.

The construction content of ventilation and air conditioning project mainly includes the installation of ventilation and air conditioning equipment, prefabrication and installation of other pipeline systems of air duct machine, installation of automatic control system, system debugging and trial operation of the project. The construction procedures of ventilation and air conditioning engineering are generally: construction preparation, processing of air ducts and components, intermediate acceptance of air ducts and components, installation of air duct system, tightness test of air duct system, installation of air conditioning equipment and air conditioning water system, test and adjustment of air duct system, and debugging of air conditioning system. 1. Final acceptance; 1. Determination of comprehensive efficiency of air conditioning system.

In fact, in our real life, our ventilation and air conditioning construction specifications are very strict, and our construction specifications have strict requirements for every link and even every part involved in our construction process. Moreover, in our country, this ventilation and air conditioning building code has different requirements and changes according to the development of our society. Every time the ventilation and air conditioning construction code changes, our installers have to re-learn the new standard system to ensure that our lives and personal safety and interests are effectively guaranteed.
