Model of the intermittent heating process of a hot water heating system;

Initial investment and operating cost are calculated for continuous heating and intermittent heating of different buildings in different places to establish the economical operation of heating sys-tems and the required capacity of necessary equipment,find out the more economical way to run the heating system and corresponding economical equipment capacity.

Introduces the mathematical mode of thermodynamic process in intermittent electric heating systems,and makes an experimental test of thermodynamic process as an example which will perhaps be available for reference during applying and designing intermittent electric heating.

But in the middle and lower reaches of Chang-Jiang river,because it is not very cold in winter,the research indicates the insulated inner wall can improve the comfortableness of the human body in the room with intermitting heating.

Directing against the relationship between the thermal comfortableness of human bodies and the room and the inner wall temperature, a mathematical model was proposed and tested for the room temperature response to the intermitting heating in a room with walls built with composite materials.

Drying process of small-diameter lumbers with intermittent heating;
