An Analytical Model for Mathematical Analysis of Smart Daily Energy Management for Air to Water Heat Pumps

Having a continuous growth in the energy demand for heating, together with decreasing the availability of fossil fuels, renewable energy sources have become an important point of departure and specially air to water heat pumps have been suggested for domestic heating. Using them the main challenge is to be sensitive to the both outdoor air temperature and the indoor energy demands to minimize the energy needs. Such a heating system should work more efficiently and economically, also taking into account comfort for the inhabitants, with minimal human intervention. This paper presents an analytical model that mathematically interprets a situation to provide insight in how to use energy more efficiently with an air to water heat pump. The results of the model have been compared with another approach which has shown more confidence in the model. This model can be integrated in a thermostat to obtain more autonomous behavior for indoor heating demands against the changes in outside air temperature over the time. © 2014 The Authors.
