Heating and ventilation design for Checkpoint
The drawings of the system of general ventilation, which we mounted on the gearbox for cars.
DESIGNING A HEATING AND VENTILATION SYSTEM
This section of the project was completed on the basis of:
- architectural and construction drawings;
- technical specifications;
- current standards and prabil:
- JV 60.13330.2012 "Heating, ventilation and air conditioning"
- SP 50.13330.2012 "Thermal protection of buildings"
- SP 131.13330.2012 * "Construction climatology"
CLIMATIC DATA
Location - Moscow. Design parameters of the outside air. Cold season:
- Outside air temperature - -25 ° C;
- Betra speed - 2 m / s
Duration of the heating period - 205 days. Warm period of the year:
- Estimated air temperature for the calculation of ventilation - + 23 ° C;
- Design air temperature for the calculation of air conditioning - + 26 ° C;
- The air temperature during the transition period for the calculation of natural ventilation is + 5 ° C;
HEATING PSD
To compensate for heat losses and maintain the required temperature in the winter period, a heating system is provided in the premises of the checkpoint. Electric heaters of the Melody Evolution type of the Noiror plinth version are used as heating devices. On the sliding doors, installation of KEV-6P air curtain curtains of the Teplomash company is foreseen. section "Automation"
VENTILATION AND AIR CONDITIONING DESIGN DOCUMENTATION
For premises PPC provides general exchange ventilation system. For premises inspection, CC, switchboard ventilation system is provided with a natural impulse. The air flow is carried out unorganized through the doorways, the hood is carried out through the vents installed on the roof of the building. For the premises of the operators provided for supply and exhaust ventilation system with a mechanical impulse. Forced-air and exhaust Ventilating installation is provided street execution. The installation includes a rotary heat exchanger, an electric heater, a filter, and silencers. The installation is located on the crab of the building on a metal frame.
In order to maintain acceptable microclimate parameters in the summer period, the project provides for the installation of an air conditioning system based on split systems by Daikin and Toshiba. ”For the room, the SS provides for redundancy of the system, as well as its addition to the winter set. for the possibility of its work on the cold at low temperatures.
EVENTS TO REDUCE NOISE AND VIBRATION
The permissible sound pressure levels created by the ventilation units in the room are taken in accordance with SP 51.13330.2011 "Protection against Noise".
To reduce noise and vibration from the outdoor units of air conditioning systems and ventilation systems, the following measures are taken:
- silencers are installed on the air ducts of general ventilation ventilation systems;
- air velocity in air ducts and in air distributors is adopted within the limits excluding the possibility of noise regeneration;
- air ducts are connected to the fan through flexible inserts.
SAFETY MEASURES
In accordance with regulatory requirements, the project provides for the following main activities:
- shutdown of ventilation systems and air conditioning system on a fire alert.
AUTOMATION ACTIVITIES
The project provides for the complete delivery of the control panel and automation of the air handling unit, which provides:
- automatic connection of the regulation system in winter and summer:
- automatic maintenance of the set temperature of the supply air.
- alarm system of normal operation and emergency shutdown of the system;
- work on schedule.
- shutdown of ventilation in case of fire, absence of differential pressure in the Fan section.
