Research on Numerical Simulation of Thermodynamic Performance in Forced Circulation Solar Water Heating System

摘要

Using numerical simulation to study solar water heating system it will be fast to obtain data and have a reasonable conditional statistical forecast. In this paper, based on the numerical model of an actual forced circulation solar water heating system, the whole year thermodynamic performance in a forced circulation solar water heating system are simulated and studied. It is shown that the efficiency of energy utilization and the heat loss of collectors in the system are closely related with the out door temperature and main efforts should be on the collectors.
