Abstrakt
Usually, it is only a few persons occupy a certain local area in a room for most of the time. In this case it is enough to just satisfy the thermal comfort of this local area rather than the whole space. In this paper, the energy saving potential by independent temperature control of each supply inlet is numerically studied based on a typical meeting room. 4 cases, i.e. 4 persons, 12 persons, 20 persons and 24 persons are set up to explore the effect under different scenarios. It is concluded that: (1) Compared with the uniform temperature control method, the energy saving can be realized at a certain degree with the satisfaction of occupied area by using the method of independent temperature control; (2) As the number of occupants increases, the difference of averaged supply air temperature between the independent control and uniform control schemes will be decreased and the energy saving potential will decrease; (3) For a fixed scenario, the different energy saving can be achieved under different schemes of supply air temperatures, where a certain optimization method is needed to determine the optimal supply air temperature. The preliminary analysis is supposed to provide reference to the creation of energy efficient environment by non-uniform air distribution.Referanser
