Emerson takes seriously its responsibility to constantly increase product efficiency in order to facilitate the achievement of the European 20-20-20 Directive targets by proactively reducing energy consumption.
Building heating and cooling systems account for approximately 1/3 of the global yearly energy consumption and therefore account for a large part of the CO2 emissions which affects global warming. Emerson, a leader in the HVACR industry is continuously investing and launching state-of-the-art products and solutions to improve energy efficiency and precise capacity control of HVACR equipment to significantly reduce energy consumption, while at the same time improving human comfort and ensuring high quality of food preservation.
For some applications, Energy Efficiency at full load (EER) is not an adequate index to rank the real energy consumption of air conditioning and heat pump equipment. The energy consumption of an air conditioning or heat pump unit is largely weather dependent. Even more, units are often selected to cover the most critical period of the year, in terms of cooling and/or heating capacity, and therefore they will be over-dimensioned for most of the time. As a consequence the air conditioning or heating equipment will run at full load for a very small percentage of its total running time, the rest of which will be at part-load operations. Emerson Climate provides different ways of modulation in order to make more efficient variable capacity air conditioning, liquid chiller packages and heat pumps. Continuous or step control of the compressor can more closely match the varying load, thus improving system efficiency.
