Dynamic Simulation for Increasing the Efficiency of Solar Cooling Systems in Northern Latitudes
Latvia lies on the eastern shores of the Baltic Sea at 57°00′N latitude. In Latvia, cooling is required about 1500 k.h degree hour (at an indoor temperature of 21 °C). This chapter presents the optimization of a solar cooling system in Latvia using the model of a solar cooling system which was created by a dynamic simulation program. The model is similar to the existing real solar cooling system installed at the Institute of Physical Energetics. The precision of the model was tested by comparing it with real equipment. Simulations were carried out using metrological data from different European countries. Simulation results, the dependency of the heat carrier average temperature and the ratio of energy from a pump to the system were collected and analysed. Different element locations of the solar cooling system were compared in two models. The annual cool production of the solar cooling system was defined.
