HVAC Consultancy

HVAC (Heating, Ventilation, Air Conditioning & Refrigeration) Systems Most of us would know the “car efficiency” that we travel 10% of our time. Hardly few of us would know the “building efficiency” that we work or live 90% of our time. Nonetheless we bring to bear dichotomy trumpet our concerns for Global Warming and blissfully shutdown our buildings for tokenism. The long past experience through two contrasting economic phases, the economic recession period of 1996 to 2002 and the economic surge period of 2003 to 2008 bring-forth a reflection. Riding high on economic prosperity our buildings have travelled far too a distance to be efficient again. Most Certified Green Buildings are actually high Carbon Intensity design Energy Guzzlers built with equally high Project Cost.


Our lack of interest for Building Efficiency Norms has brought in numerous Barriers to Energy Efficiency majority of which are attributable to HVAC System which alone contributes to over 50% of a Building's Energy PIE. Please visit our “Knowledge Center” for knowing details of Green Building and its Energy Efficiency Norm which is defined as SEC (Specific Energy Consumption) of a Building. It is a culmination from our conducting several hundred Energy Conservation Projects for several hundred Intelligent Buildings across the length & breadth of India and Worldwide. It includes all types of Green Intelligent Buildings like Hotels, Service Apartments, Hospitals, Shopping Malls, Shopping Complexes, Commercial Buildings, Corporate Buildings, Corporate Head Quarters, IT/BT/BPO/Industrial Parks, Industrial Production/Process Buildings, Industrial Warehouses, Air Ports, University, Engineering College, Medical College, College Campus and Hostels.


Types of Air Conditioner and its Selection Criteria are determined by the Size of the Building. Window Air Conditioners are used for single room type applications. It makes lots of noise and thus goes with lower budget. Split Air Conditioners are best suited to cool one or two rooms. Window & Split air conditioner has limited capacity application usually within 5tons. Air Cooled Ductable Split/Package Air Conditioners or Direct Expansion DX VRV (Variable Refrigeration Volume) Air Conditioner finds its application in medium size buildings due to its ease of operation albeit very low IKW/TR Energy Efficiency and thus high Electricity Bill. When building size is big enough and its air conditioning load is in excess of 200TR both the Package and the VRV Air Conditioners become hugely Energy Guzzlers with very high Running Cost. Centralized Water Cooled Air Conditioning System is the only Energy Efficient option for any 200TR plus Air Conditioning Project. It has the best IKW/TR Energy Efficiency. Most Commonly used efficient Centralized Air Conditioning Machines are Screw Chiller and Centrifugal Chiller.         


Conventional AC Design unlike Intrinsically Efficient AC Design uses higher rating Chillers that pumps much excess Cooling Energy at the “High Side Air Conditioning System” which interconnect the Building using one common network of Chilled Water Piping System that reaches at every Low Side Delivery End like in Rooms, Conference/Function/Seminar Halls, Operation Theaters etc. Thereafter the excess cooling energy is regulated using a series of Sophisticated Control Devices/ Systems.


Encon Smart Intrinsically Efficient AC Design ensures achieving SEC Norm within the limits of Green Building Code that we have done for over hundreds of Green Buildings Worldwide. Low Side Air Conditioning System Design depends upon Indoor Air Quality Norms.
