Samenvatting:
A lot of simultaneous processes do occur in a building. With the increase of the number of devices for heating and cooling of the building, there is a higher risk of one device counteracting the other. This leads to unnecessary loss of energy. It is becoming harder for conventional comfort control systems to satisfy the objective: ‘provide thermal comfort at the lowest energy use’. Multi-agent systems for climate control can offer a number of advantages in this field because of their bottom-up modelling principle starting from the low-level primary process, in this case comfort control. The aim of our research in the Flexergy project is to design a Multi-agent climate control system for buildings and domestic dwellings as well. In the process of obtaining this, an intermediate goal as an objective for a study was spontaneously formulated. During the operation of a central control system for a representative office building in the Netherlands, it was observed that, due to high insulation, solar irradiance and internal heat sources, the net demand for cooling over a year is higher than for heating. As a heat pump connected to an aquifer was responsible for delivering the cooling power it was also observed that the temperature of the aquifer increased. This decreases the availability of cooling power for the building in near future. The question was raised how a Multi-agent could help to retain the energy balance of the aquifer over a year. It was suggested that two technical possibilities to retain this balance could be exploited: first to cool the building by outdoor air during the morning hours by an air conditioning unit and second to load cold during the night with a bypass preventing warm air from entering the building. This study describes the details of a design of a simplified Multi-agent climate control aimed at retaining the energy balance of the heat pump connected to an aquifer, exploiting the ability of the PowerMatcher to trade two or more commodities through the use of the above mentioned methods [2].
