Feature and selection of various heating methods;

This paper introduces various heating methods, and makes comparison for every heating method in aspects of the practicability, the nonrecurring investment and operation fee, and points out that the most economic and practicable heating method should be selected prudently through comprehensive evaluation of the nonrecurring investment, operation fee and local resources condition.

This also supplies reference to select and design heating methods for Lanzhou region.

Comparing with the traditional rediator heating,the result shows that it is a more perfect heating mode.

This paper illustrates the diversity of heating design temperature in breeding buildings,proposes the equation to calculate heating design load specially owned by breeding buildings,and points out the settlement of heating mode of breeding buildings,in order to make reasonable heating design with feasible technique,low cost and flexible adjustment.

Through analyses in quality and quantity of the conditions of energy sources, lack of oxygen, permafrost, environmental protection and so on along the Qinghai-Tibet Railway line, a rational heating mode, adaptable to the local economy con-dition, is put forward.

Research is processed in the field to learn about the main structures of energy and the types of residential constructions and heating systems in local small towns of North China.

Therefore, establishing thermal environment standards for buildings in small town and improving building envelope, heating methods and air-conditioning system are getting more and more important.
