Industrial and commercial customers looking to air condition multiple locations from a centralized source will find an energy efficient and viable alternative in the recently set up facility at Thermax’s Chinchwad factory. Here, triple effect absorption chillers triggered by heat from a boiler using agro-waste as fuel, pump chilled water to several buildings in the factory complex. This clean energy facility is based on the district air conditioning concept of a centralized source transmitting hot or cold water through pipe lines to different sites. The facility uses Thermax’s energy rental business model of charging per unit of cooling. Clients need not invest in the boiler and chiller facility, but can have them installed at their site and pay for chilled or hot water, metered as per use. The integrated facility offers the efficiency of triple effect chillers that use 35% less steam to generate comparable levels of cooling. The reduction in energy consumption makes the system an attractive option as air conditioning accounts for the major load of any building. The CFC free chiller using water as a refrigerant can work on hot water, steam and exhaust. The boiler supporting the chiller uses the combustor technology for biomass systems that Thermax has adopted from Lambion, Germany. The green energy system is suitable for segments like hotels, IT parks and malls requiring large air conditioning loads.
