Optimisation des performances non nominales des pompes à chaleur réversibles pour le secteur tertiaire

Abstract : Seasonal performance optimization of reversible heat pumps contributes to the reduction of energy consumption in the commercial building sector. A detailed thermodynamic model of a commercial heat pump (compressor, condenser, expansion valve, evaporator) at off-design conditions is developed. The heat pump model, validated by experiments in laboratory and in-situ, is coupled to a building thermal load model to evaluate the seasonal performance of the heat pump and to improve its design according to this criterion. Seasonal performance optimization is then led to respond to two different objectives: - Local perspective optimum: optimization with respect to a specific installation with focus on heat output regulation or prioritizing design optimal design in heating or in cooling mode. The seasonal optimization of the heat pump is carried out on an office building for different building characteristics (new and existing) simulated under different climates in order to test the sensitivity of the results. - Industrial point of view optimum: integration of innovative devices to support competition and to increase the product ranking for performance labeling. The performance improvements are completed with a technical-economic study, based on the heat pump main components costs decomposition. Finally, the payback time of the optimized heat pump is determined for the different building and climates.
