In the design of cold and hot water supply system in a high rise hospital building with 888 beds,a whole closed energy-saving and water-saving system was designed for supplying hot water with anti-Legionnella electric water heaters.

Design of data display program of DS12887 in the intelligent water saving system;

Application and development of energy saving system of injection moulding machine;

The basic formation,working principle and experimental research method of power matching energy saving system of the digital control variable displacement pump are introduced in this paper.

This paper introduces the method to design the classroom intelligent energy saving system.

The research of systematic energy saving in alumina industry

Many measures to reduce the energy consumption and the proposal of standard material flow diagram at Xuanhua Steel are presented,based on the idea and theory of systematic energy saving and analysis of the practical energy consumption and flows.

The article expounds anoverall conception and method of systematic energy saving.

Emphasis is not put on energy saving of single equipment, but on improving the function of waste heat recovery apparatus, pursuing system energy saving policy and developing the new energy saving technology base on introduction and absorption of advanced ones, which results in good during operation.

Based on the idea of system energy saving,the paper analyzed effects of restricting output on comprehensive energy consumption of per ton steel in incorporated business enterprise of iron and steel,pointed out the way and the idea of structure adjustment to keep and cut down comprehensive energy consumption of per ton steel.

This paper take the city construction enclosure structure and the system energy saving as a basic point,introduced several pointed energy conservation methods,and carried on the concrete analysis to these methods.
