VENTILATION. Design engineering systems HVAC
A ventilation design is used to build and repair a building's ventilation system. Ventilation drawings are an important part of the project for the entire building. Ventilation drawings are developed for public administrative buildings, offices, business centers, municipal buildings, and for private and commercial real estate - cottages, shops, restaurants, cafes, coffee points, dry cleaners, pharmacies, cinemas, car washes, canteens, hookahs, etc.
VENTILATION DESIGN
Creating a design section of ventilation as part of a project kit for a new building is imperative. The developed ventilation project displays the location and connection of the elements of the building ventilation system, drawings can be made in the AutoCAD program, in this program the engineer-designer can easily create and combine ventilation plans of any complexity.
The equipment of the ventilation system displayed in the project includes: intake fans, exhaust hoods, local suction pumps, frequency converters, filters, heat exchangers, heaters, humidifiers, steam generators, noise suppressors, diffusers, ventilation grilles intake and exhaust air dampers, round flexible and rectangular air ducts, noise insulation and heat insulation, pumps, valves, automation system.
Ventilation is necessary to create comfortable conditions for a person indoors. Ventilation design is a subsection of mechanical engineering systems based on the laws of thermodynamics, fluid mechanics and heat transfer. The ventilation system is important in the design of small to large industrial buildings and office centers, skyscrapers, dolphinariums, shopping centers, logistics facilities, warehouses, airports, train stations, private apartments, hairdressers, barbershop, pizzerias, barbeque, etc., all those places where safe and healthy air parameters are maintained in terms of temperature and humidity using fresh air from outside.
DEVELOPMENT OF ENGINEERING VENTILATION
Air ducts are used in a ventilation project to deliver fresh outdoor air inside the building to each room. Air ducts are used for supply air and exhaust air. The duct system is often referred to as ventilation layout. When designing air ducts, it is necessary to calculate pressure losses, air flow and air velocity. You need to be an expert to design a duct system for proper distribution of air to each room, optimize losses and prevent noise.
The ventilation project may contain: an explanatory note of the PP, general data, a table of air flow rates, floor plans, axonometric schemes of ventilation, enlarged detailed joints of various elements, specifications, estimates. The working and design documentation of the ventilation system can be developed for homes, hypermarkets, shopping and entertainment centers of shopping and entertainment centers, water parks, Sushibars, kitchens, catering establishments, hotels, hotels, saunas, baths, hospitals, dentists, clinics.
When designing ventilation, it is important to consider the energy efficiency of the system being created. There are many details that save the customer electrical and thermal energy in the process of using ventilation. Such solutions may include recuperators, inverters, automation systems. Special requirements ventilation is often designed for operating rooms of medical institutions, cosmetologies, plastic surgery clinics, fitness centers, schools, kindergartens, multifunctional centers, underground parking lots, basements, factories, hazardous industries, banks, banks, swimming pools, car services, universities, pig farms , business centers, combines, konferenzalov, metro, bus stations.
WORK DOCUMENTATION OF HVAC
In the process of developing a ventilation project, it is necessary to perform: calculating the loads for heating and cooling the air, calculate the necessary air flow depending on the number of people in the room and the air flow rate, calculate the air temperature, calculate the air exchange rate, calculate the temperature loss in the ducts, calculate the sizes of the fan units , heaters, taking into account their placement, the calculation of the cross sections of air ducts.
