BIG LEAP IN DEMAND CONTROLLED VENTILATION
A blueprint for efficient and intelligent HVAC systems that monitor the requirements and make adjustments accordingly to affect significant energy efficiencies and at the same time provide optimal ventilation rates.
In this article we have discussed the various approaches both traditional and new, with illustrations and outlining their advantages and drawbacks.
ON DEMAND VENTILATION FOR CAR PARKS
The main factors determining the characteristics of a parking ventilation system is the approximate number of cars serviced on a daily basis and the nature of construction of the facility that it caters to.
Discover the essentials of an intelligent system that can monitor and control ventilation while optimising your energy costs at the same time.
ZONE REGULATION OF OUTDOOR AIR IN HOTEL ROOMS
Comfort and luxury are two main criteria for planning facilities in hotels. Typically energy costs of a an average five star hotel consume up to 18 per cent of its revenue. HVAC systems account for upto 40-45 per cent of this chunk.
A key requirement thus becomes the HVAC system that will determine the temperature and quality of indoor air. The idea is simple, save energy, save revenue, hence more profit.
IMPLEMENTING FIRE & SMOKE CONTROL IN HVAC SYSTEMS
Fire Dampers are required by all building codes. A basic requirement of building fire protection is the compartmentation of of buildings to contain any fire to its zone of origin and prevent it's spread through the HVAC system.
Smoke Dampers on the other hand can be effectively deployed to control and shut off the circulation of air and smoke as part of an Engineered Smoke Control System.
CONTAMINATION CONTROL THROUGH ROOM PRESSURISATION
Proper room pressurisation is critical for preventing unwanted air transfer. In chemical and biological research facilities chemical fumes and airborne biological agents must be prevented from migrating out of laboratory rooms to non-laboratory areas.
The answer lies in maintaining a differential pressure relationship, Discover a number of possible approaches to design such a system.
CLIMATE CONTROL WITHOUT WIRES
With increased demand for intelligent and efficient climate control systems, more and more HVAC installations deploy VAV/VAQ terminals. However, installation of these VAV terminals with thermostats and sensors present numerous challenges.
Extensive wiring in confined spaces, integration with BMS, not to mention the challenges in operation and maintenance of this system. We present a solutions that cuts through this clutter.
HOW TO CHOOSE THE RIGHT AIR OUTLET
Contrary to popular perception a grille is not merely a standard fabrication item, but a product of engineering perfection that determines it's life, performance and aesthetics.
Choice of an appropriate grille/diffuser is based on a number of considerations, ranging from air delivery requirements, size and height of the space, sound levels and appearance.
IMPLEMENTING NOISE CONTROL IN HVAC SYSTEMS
The HVAC system during its operation generates a number of sounds at various stages. All these sounds add up and often exceed the threshold of tolerance and are thus interpreted as noise.
For a silent and noise free HVAC system, there are some simple guidelines that can help you identify and understand the sources of noise and minimize their effect.
ENSURING OPTIMAL INDOOR AIR QUALITY
CO2 concentration inside buildings can go upto several thousand ppm. Intervention research has shown that higher levels of CO2 in indoor settings are associated with slower work performance, impaired decision making, increased absenteeism.
The answer? Ventilation systems with built-in energy recovery that will keep your energy costs in check while ensuring optimum ventilation.
