Abstract:
In the actual application of the system in buildings, the photovoltaic-thermoelectric system with micro-channel heat pipe will be heat loss and waste in the whole year operation process when the hot and cold ends of thermoelectric devices constantly change. In order to solve this problem, this paper proposes a kind of micro-channel heat pipe which uses three-way valve to switch the direction of heat flow, and compares two modes of changing the direction of three-way valve by time and by season. Based on Simulink software to establish the numerical model of the new type of solar thermal power system, according to the annual indoor and outdoor temperature during the operation of changing direction of three-way valve switch to analyze system performance, comparing with traditional solar thermal power system at the same time, the results show that the switch moment three-way valve of the micro heat pipe system efficiency can be 18.75%.
