National Museum of China is located on the east side of Beijing Tiananmen Square, the south side of East Changan Street, opposite to the Great Hall of the People. It is a comprehensive museum that systematically displays Chinese culture and history. It has a total construction area of nearly 200,000sqm and a collection of more than 1.2 million pieces. It is the largest museum with a single building area in the world and one of the richest museums in collections. In 2012, it received 5.37 million visitors, which made it become one of the most popular museums in the world. Attached to the ministry of culture of the People's Republic of China, it is a comprehensive museum integrating collection, exhibition, research, archaeology, public education, and cultural exchange. It has gone through a glorious journey of one hundred years, recording the footprints of Chinese civilization of five thousand years and showing the glorious achievements of our great motherland in history, culture, art, and social development. It is the spiritual home for the Chinese people to inherit history and explore the future.
Accessen supplied nine sets gasket plate heat exchanger for this project. Nine sets gasket plate heat exchanger expecially for HVAC industry.
Ice storage air conditioning is an air conditioning system that uses electric refrigeration set to make ice during the electricity troughs at night, stores the cold energy in ice storage barrel in the form of ice and releases the cold energy of ice in the barrel by plate heat exchangers to meet the demand of cooling load during the electricity peak in the daylight. Ice storage technology is a combination of load management and peak-clipping technology, which moves the peak demand for electricity to off-peak periods and saves up to 30 to 50 percent of electricity costs compared to conventional cooling systems. Nowadays, China has the second-largest installed power-generating capacity in the world, but it still can’t the meet electricity consumption; the difference of the consumption of power grid continues to increase between summer and winter, and there’s also a big difference between daylight and night. New power plants can’t solve the increasing peak-valley difference by power supply side regulation. Air-conditioning power consumption usually accounts for 40-60% of the whole building’s electricity consumption, and after the use of ice storage air conditioning, the imbalance of power grid caused by the unbalanced load of air conditioning during peak and valley periods can be greatly alleviated. Therefore, electric power department of many cities in China has released the time-of-use pricing structure and a lot of other related preferential policies. Through these preferential policies, operating costs can be reduced to encourage people to use ice storage air conditioners. The investment payback period of ice storage cooling system is usually 3-5 years, which has good economic and social benefits.
