Target for heat capacity consumption that considers safety, energy savings, and comfort: a room heat capacity model using a two-phase difference integration method

Abstract

In this study, the thermal characteristics of an individual room in a building are measured by making use of environmental data. Subsequently, the target heat capacity consumption by the air-conditioning system can be calculated and controlled, depending on the environmental target. By establishing the relationship between a change in the room environment (environmental evaluation index) and the heat capacity consumption of the room (the amount of change of the enthalpy) by the air conditioning, we can calculate the target heat capacity consumption feasible as an environmental target. Relying on an environmental target in calculating the target heat capacity consumption enables setting suitable targets to avert the risk of heat exhaustion or even heatstroke to the residents of the building. In addition, a useful room heat capacity model is suggested that includes a management method using a heat capacity consumption target, with an administration table for evaluating the target.
