Description

Double Cooling Condenser Heat Pipe Type Photovoltaic Photothermal Module-Trumbert Wall System and Method

technical field

The invention belongs to the field of combining photovoltaic photothermal technology with buildings, and particularly relates to the application of a heat pipe type photovoltaic photothermal system combined with a Trumbert wall in buildings.

Background technique

Solar Photovoltaic Photothermal Technology (PV/T) combines the functions of traditional solar photovoltaic panels and solar collectors to provide both electrical and thermal energy. In order to solve the problem of freezing inside the photovoltaic thermal module in winter, the heat pipe technology is introduced into the photovoltaic thermal system. At present, most of the heat pipe photovoltaic systems use a single cooling mode, such as single air cooling and single water cooling, which limits the output function of the system.

As a mature heating structure wall, Trumbert wall can heat indoor air through natural convection or forced convection heat exchange. The combination of Trumbert wall and photovoltaic photothermal technology increases the application form of PV/T. However, the Interlambertian wall only uses a single cooling method, and its photoelectric, photothermal comprehensive efficiency is not higher than 45% in the state of natural convection or forced convection cooling. Most of its energy is dissipated outdoors in the form of heat loss, so it is potential and necessary to use various forms of cooling photovoltaic modules to improve their overall photovoltaic efficiency.

The Chinese patents "A Heat Pipe Photovoltaic Photothermal Component" (CN201310539314.4) and "Heat Pipe Photovoltaic Photothermal Integrated Board" (CN201310475617.4) all use a single water cooling mode to achieve the function of heating water. "A Solar Multi-Function Wall" (CN201410558931.3) introduces a natural convection heat transfer Trumbert wall heating and formaldehyde removal system, "A Solar Heat Collection Ventilation System for Passive Houses" (CN201820406956.5) The solar collector, heat pipe and Trumbert wall combined with hot water system are introduced. These systems all use a single cooling method, and the solar energy utilization efficiency needs to be improved.
