Abstract
AbstractThe aim of this chapter is to evaluate the potential benefits of integrating latent thermal energy storage (LTES) in a system with solar thermal collectors and water-water heat pump in order to use solar energy as a heat source and to enhance system efficiency. Three system configurations are considered to evaluate and compare system performances. The referent system implements LTES in the solar collectors loop. During daily regime, the heat pump is operating using energy from outside air as an energy source, while energy from solar collectors is stored in LTES during melting of the phase change material. Thermal energy stored inside LTES has been used as a heat source for the heat pump during night operation. The referent system has been compared with the system containing sensible thermal energy storage instead of LTES as well as with the system without storages and solar collector loop. The simulations over the winter period have been performed in software TRNSYS using climatic conditions of the southeast European location. The analysed systems were compared in terms of total and auxiliary heater electricity consumption, operating costs, as well as coefficient of performance (COP) of the heat pump.KeywordsHeat pump systemlatent thermal energy storagesolar energy system
