Samsung announces the EQ Series that is an upgrade to the existing model, BK Series that has been produced from 1999, and is currently utilizing this technology in its Samsung Brand premium refrigerator and other facilities for major customers. The household refrigerators that have adopted the EQ Series have won the best Prize of Energy Winner in 2005 in the domestic (Korea) market and the excellence of the product was verified by domestic consumers. The Energy Winner Prize is awarded to the most efficient product that was launched in the year. 'Digital Variable Compressor The reliability of EQ Series has been verified by the compressor test and refrigerator application test for over 1 year. The ALT (Accelerated Life Tests) which is a type of test dealing with extreme operat. Capacity (Btu/h)ASHARAE Conditions Distinguished excellence of the EQ Series is proven by the fact that the variable speed type of BLDC Motor has replaced the existing constant (single) speed type of AC Motor and saved 30% of electric power consumption, EQ Series has dramatically improved the system operation efficiency by both the BLDC Motor of high efficiency and Inverter Controller. The increased efficiency has been estimated as a world's best level in the same displacement of inverter Compressor. Furthermore, not only is the energy efficiency advanced but also the noise level which is regarded as one of the most critical factors of the compressor, is lower than the domestic major competitor by 2~5[dB/A]. This technology power of Samsung compressor has been featured by a lot of international journals and conferences. The Inverter Controller of EQ Series can offer not only optimum cooling capacity and operating conditions corresponding to changing refrigeration Cycle's load through continuous speed control, but also satisfactory noise level by using Soft Start algorithm. ing conditions, HALT (High Accelerated Life Tests), HASS (Highly Accelerated Stress Screens) are included and these tests are conducted by CS Management Center which is called as a reliability specialist group of Samsung. EQ Series, which is one of DVC(Digital Variable Compressor) categories, has a maximum displacem -ent (15.3cc/rev) and cooling capacity range(540~ 1290BTU/H, AHAM in Inverter Compressor of R600a products, and uses from 1600 to 3800 RPM in addition, it has also has a dis-placement (8.8cc/rev) and cooling capacity range(445~1148 BTU/H, ASHRAE) in Inverter Compressor of R134a products, and uses from 1600 to 3800RPM. Therefore, the EQ Series will possibly be applied to the various types of refrigerators, especially to premium refrigerators with large capacity and Built-in refrigerators with more than 600(l). in conclusion, this high efficiency technology with a large capacity Inverter Compressor is expected to have a great, impact in the America and Europe market. ------------------------------------------------------------------------ * www.samsung.com * privacy * legal * site map * contact us Copyright© 1995-2008 SAMSUNG.
