Resumo

Indoor heating is a significant source of the total residential power consumption in northern countries such as Canada. There has been some interest in achieving optimal heat distributions to lower energy consumption, but most works have focused on existing heaters. Recently, a new approach to solve the problem of optimal indoor heat distribution was introduced. The concept called virtual heater finds the heat distribution that optimizes energy consumption, via thermal comfort constrained optimization, by varying the temperature distribution in a room. Using the maximum and minimum heat consumptions, the total energy consumption sensitivity to heat distribution can be assessed. It has been determined that window geometry, window glazing and air exchange rate are significant parameters affecting a room's heat distribution sensibility and optimal heat distribution. In this paper, the virtual heaters are used to explore how the power consumptions sensitivity to the heat distribution of a room might change with respect to these three parameters. This is achieved by first finding the virtual heaters for specific cases, then calculating the room's heat distribution sensibilities. These are then compared with each other and the most sensible room parameters to heat distribution are found.
