1 In any centrally conditioned environment, health, well-being and performance capability of people are largely dependent on an optimised climate.

Amongst the key factors which influence this optimal climate are indoor & outdoor air quality.

Individual climate control in zones and proper distribution are equally important to take care of individual comfort.

Balanced temperature, low noise in public areas are the other key factors for individual comfort.

CLIMATE CONTROL FOR CENTRALISED AIR CONDITIONING SYSTEMS 1A

2FIRE & SMOKE MANAGEMENT IN CENTRALLY AIR CONDITIONED SYSTEMS

One of the basic requirements of building fire protection as required by all building codes is the compartmentation or division of spaces using fire rating walls, floors, or other partitioning methods.

This compartmentation is intended to contain any fire to the compartment of the fire origin and thereby minimise damage to property and protect the lives of people living and/or working in the building.

Commonly used Smoke Control practices are:

Passive Smoke Control is simply shutting off the circulation of air and smoke through ducts or ventilation openings.

Engineered Smoke Control is exercised by creating pressure differences through dedicated fans & smoke dampers.

Staircase or Lift well Pressurisation is required to provide a smoke free escape route in the event of a fire.

2A

ENGINEERED SMOKE CONTROL SYSTEM

Higher pressures surround the fire area and prevent the spread of smoke from the fire zone to other areas. In this application, the smoke dampers are motorised with electric or pneumatic actuators.

They can be controlled by a interconnected damper control modules with connected smoke or a heat detectors, or in a variety of ways by the building control system to accomplish the intent of design.

Smoke detector module, suitable for air velocities upto 2000 fpm and duct mount option is also available.

20 21

2B

STAIRCASE OR LIFT-WELL PRESSURISATION

Pressure sensor integrated with smart Damper Control module is used to provide ultra fast pressure compensation when doors are opened during evacuation to prevent smoke back flow.

Both bypass damper or VFD control are available as per requirements.

2C

FIRE DAMPERS

A duct or ventilation opening in any of the fire rated partitions would permit a fire to spread from the compartment of origin to adjoining compartments.

Fire dampers are installed in these ducts or ventilation openings. Upon detection of heat, these dampers close (at melting of a UL Stamped fusible link or through a thermal cutoff and solenoid) thus blocking the opening and preventing the spread of fire into the adjoining compartments.

In modern buildings contaminants, toxic gases, and volatile organic compound need to be maintained within the limits. Unmanaged concentrations lead to ‘Sick Building Syndrome’, reduced productivity levels of the occupants or even health hazards or illness.

Demand Control Ventilation (DCV) effectively helps maintain optimal ventilation while saving energy costs, by monitoring indoor air quality using carbon dioxide or other contamination sensors from within the breathing zone. It helps in:

Routine flush out for removal of contamination, which reduces indoor airborne viruses and bacteria

Monitoring of the outdoor air coming into the building

Optimise outdoor air as per multiple space requirement with suitable energy recovery ventilator

Reduce the cost of operating HVAC system with advanced application specific controller

BUILDING INTAKE & EXHAUST

Demand control ventilation can be effective only if building intake & exhaust is properly designed and selected. This can be achieved by installing application specific architectural louvers, that allow air to pass through while keeping out unwanted elements such as water, dirt and debris.

Key factors in the selection of louvers are the free area, water penetration, and resistance to airflow. Other performance features are sand protection, sound absorption, back-draft damper for restricting air flow in one direction. Some of the special purpose louvers and back draft dampers for building intake & exhaust openings are:

DRAINABLE LOUVER

Incorporates drainable head member and fixed horizontal louvers to channel water towards jambs which guide the water through vertical downspout for escape at the sill.

ADJUSTABLE LOUVER

CONTAMINATION CONTROL

Contamination control with room pressurisation can have requirements as varied as hospital isolation rooms, to chemical or bilogical labs, to protection of equipment in industrial ventilation. It helps in:

Prevention of surface discolouration (smudging)

Removal of odours and VOCs

Prevention of various respiratory diseases and ailments

Prevent spread of airborne hazards in laboratories

Protect patients and staff from germs

Facilitate sterile compounding in pharmacy

Maintain product quality for clean manufacturing

Prevent corrosion and maintain copper and silver reactivity levels

Key requirement is to establish the hygiene limit on the basis of Indoor Air Quality - Climate & pollutants within the space contamination, noxious gases and pollutants in the ambient air and then, optimised ventilation for proper IAQ & contamination.

Achieve desired air movement for balanced air distribution & mixing.

Remove infiltration and exfiltration - unwanted leakages. Thereafter providing necessary contamination control.

PROCESS CONTROL

Industrial dampers may be used to divert hot exhaust from gas turbine exhaust to recovery boiler, or to shut off process for maintenance, or to regulate gas or airflow in process control. Its operation can be manual or motorised.

Various applications of Industrial dampers are as follows:

Isolation dampers are used for isolation or shutoff in industrial processes with extreme pressure and velocity system. Dampers with tight seals and minimum leakage, having low pressure drop are suitable for such applications

Control dampers are used for flow control in extreme pressure and velocity systems. Dampers having better flow characteristics and control options are recommended for this application

Pressure relief dampers are used for pressurisation systems, gas fire extinguishing systems, internal spaces with explosive atmospheres or transformer substations

Such dampers require performance and integration testing, our in-house air performance testing facility as per AMCA enables us to design and test dampers for any challenging process control application.

CONTAMINATION & CORROSION CONTROL

Different applications require different degrees of air cleaning effectiveness. In industrial applications, removing only the larger dust particles from the airstream may be necessary for cleanliness of the structure, protection of mechanical equipment and employee health and in some cases prevention of surface discolouration, in which case the smaller components of atmospheric dust are the worst offenders. Electronic air cleaners or medium to high efficiency dry filters are required to remove smaller particles, especially the respirable fraction, which often must be controlled for health reasons.

In clean room applications or when radioactive or other dangerous particles are present, high or very high efficiency filters need to be deployed.

Intended for use in pressurisation systems, gas fire extinguishing systems, internal spaces with explosive atmospheres or transformer substations Also available in construction which complies with the requirement of ASME AG-1 DA, N509

HYDROGEN SENSOR

For Electrical Safety in the workplace, building owners can find requirements for safely designing a battery charging room. This requires a ventilation system to exhaust air from the room to the outdoors. Since hydrogen gas is lighter than air in the room, it should be exhausted from an adequate height in the room. When its concentration rises to level above 4% there is a substantial risk of explosion.

Explosive gases such as hydrogen in battery charging should be limited to 1000 ppm for prevention of explosion.

Complies with the requirement of article 320 of NFPA 70E

Accurate Hydrogen sensor measuring range of 1000 ppm
