Cooling Systems Optimization
Modern trends to increase energy efficiency in the building industry more frequently pre-determinate an approach to elaboration of design decisions for engineering systems. It is very important to correctly determine and choose a concept of more efficient system on this stage. The company Carrier shared its experience of efficiency estimation and cooling system optimization for buildings.
The Moscow office of the company AHI Carrier organized a technical seminar “Eco and energy efficient solutions in HVAC from CARRIER.” As speakers there were foreign specialists from the main office of the company and workers of the Russian office too. Among guesses there were workers from leading design bureaus, investment and dealer companies and customer’s representatives too. All noted the high grounding of specialists, richness of reports content and topicality of issues touched upon.
Some topics of the seminar were dedicated to building energy efficient increasing, reasonable usage of waste heat from cooling equipment and transformation into useful energy. A new product from the screw chiller line Carrier 23XRV (“Under the sign of the platinum LEED”, “TB” No 5, 2011, P. 110 – 113) was presented. Actual indexes of chiller efficiency and complex approach for energy efficiency estimation of cooling system were considered.
Sumanth V.G., a sale manager in Russia, and Dmitry Suevalov, a marketing director, were among first speakers. Jointly they presented estimation criteria for cooling system efficiency applying energy efficiency indexes SPLV. Currently the most popular estimation criterion for cooling machine efficiency is an index COP (coefficient of performance) which demonstrates efficiency of chillers under full load and nominal temperature of liquid on evaporator and condenser (condensation temperatures). For several machines a value varies in dependence of type of compressor, condenser, design temperature of liquid and condensation.
