THE BASIC EQUATIONS OF TRANSIENT ROOM TEMPERATURE FOR MULTI-ROOM IN CONSIDERATION OF MUTUAL RADIATION IN ROOM SURFACES : Part 4. Heat Equilibrium of Some Special Surfaces and Distribution of Roots for D (s)=0

Abstract

In this paper, first, are discussed heat equilibrium equations for four special surfaces without being discussed in Part 1. Four surfaces are as follows; 1. heating surface 2. temperature controlled surface 3. openings 4. semi-opaque window glass surface, and the form of coefficient matrix A (s) is shown in several cases. And next, the distribution of roots for characteristic equation D (s)=0 is indicated.
