摘要
Based on the power balance equation, an analytical tool for the calculation of the free-run-temperature of a room has been developed and a universally valid energy-strategy derived. The description of the thermal behavior of a room is traced back in this approach to three parameters only: the generalized loss-factor K, the time constant tau and the gain-to-loss ratio gamma. By an appropriate inclusion of solar gains the usual definition of 'heating-degree-days' is extended to 'generalized heating-degree-days', represented graphically as a function of tau and gamma. These two parameters yield the 'climate surface' of the room under consideration, A comparison with measured data from actual buildings confirms the validity of this approach. In order to illustrate its practical value, the method of climate-surfaces is applied in this paper to generate surfaces for design-temperature differences and to deduce optimized heating, cooling and control strategies, as well as strategies for the night set back, solar shading, night cooling etc. (C) 1998 Elsevier Science S.A.
