2006 end of the year, China started to "storage-type Water Heater Limit value of energy efficiency and energy efficiency rating "standard-setting work, and endorsed by the National Development and Reform Commission (NDRC), United Nations Development Programme (UNDP), Global Environment Facility (GEF) co-sponsored by the China End Use Energy Efficiency Project (EUEEP) support. June 2007, the National Standardization Management Committee formally approved the "storage-type electric water heater efficiency limit value and energy efficiency rating" project; the end of 2007, after the standard preparation group effort, "storage-type electric water heater efficiency limit value and energy efficiency rating" completion of the development and approval; April 1, 2008, GB21519-2008 "storage-type electric water heater energy efficiency and energy efficiency level limit values", and is planned for November 1, 2008 into effect. The scope and parameters of energy efficiency evaluation At present, people use the water heater to the main storage-type electric water heater, or thermal, heat pump water heaters are also momentum of rapid development, such as temperature and electric water heater is energy-saving, compact, saving time by industry and other factors concern. In view of the hot type, pump type electric water .. more»

Topics Covered: Current Areas of Development Additional Applications and Drivers of DC Power Organizations and Alliances Involved in DC Power DC Power and Alternative Energy Systems Barriers, Challenges and Threats to the Adoption of DC Power Architectural and Technology Trends and Developments Cost Dynamics of DC Power Policy and Regulatory Framework for Development Recent Developments and Products Executive Summary The dc building power market is projected to grow significantly over the next several years, and among the driving forces is the need to improve efficiency and reduce electricity costs in several areas. According to the US Environmental Protection Agency (EPA), in 2006, data centers and servers in the United States accounted for approximately 1.5% of the nation's total electricity consumption. To put this in perspective, the EPA stated that this total exceeded the electricity consumed by the entire nation's color televisions, and is similar to the amount of electricity consumed by approximately 5.8 million average TV households. In addition, energy consumption in data centers in the US is projected to continue to grow, and double every five years. Traditionally, large data centers and telecommunications facilities .. more»
