Energy Saving Strategies for Ice Rink using Sea-Water Heat Source Cooling System

According to China's current energy present situation, the use of renewable energy, saving energy and reducing consumption has become the energy industry development should follow the basic principles. Ground-source heat pump and conventional heat source composite system as a kind of building energy efficiency technology, mainly reflected in soil source heat pump renewable energy utilization aspects. In this paper the soil source heat pump and conventional heat source matching design and operation mode research, from the matching design principle chart, operation mode, the practical engineering application, economic and technical analysis into consideration, it is concluded that the soil source heat pump and conventional heat source composite system can be applied and research.

AbstractIn this study, surface remelting treatment of the AZ91 magnesium alloy by means of welding using a non-consumable electrode in an inert gas shield was carried out. Three variants of surface treatment were used, i.e. the single torch variant with a single heat source without cooling down the samples, the single torch variant with a single heat source and a cooling system with liquid nitrogen, and the double welding torch variant with a double heat source in the torches operating in a tandem configuration. Experimental verification of the applied apparatus solutions was based on both macro- and microstructural assessment of the obtained effects. Comparative analysis of the variants used and the obtained microstructural results allowed the authors to indicate the deficiencies and limitations of particular solutions and to single out the best solution that would be useful for modifying the surface layers of magnesium alloys, as well as other materials having a strong oxygen affinity.
