Winter time-controlled type ventilation window of concentrating photovoltaic electric heating coupling ventilation system

Abstract

The invention discloses a winter time-controlled type ventilation window of a concentrating photovoltaic electric heating coupling ventilation system. The ventilation window comprises a window body assembly, a concentrating photovoltaic cell plate (5), an air port baffle (13), a control device, a driving device, an air inlet heating assembly and a noise reduction filter channel box (12). The window body assembly comprises an integrated window frame (1), a window sash (2) and two pieces of hollow glass on the two sides. A heat preservation and ventilation flow channel (3) is formed between the two pieces of hollow glass. The control device comprises a photovoltaic controller (14) and an accumulator (15). The driving device comprises a servo motor set, synchronous drive shafts (18), a synchronous belt (19), rotating shafts (4) and fixed bearing seats (20). The air inlet heating assembly comprises an air inlet channel box (11) and a phase change heat pipe-electric heat pipe complementary heat sink. The electric energy and waste heat of a photovoltaic cell are fully utilized, and meanwhile timing control over ventilation and fresh air heating is achieved, so that the problem that the ventilation effect of the window is incompatible with the indoor heat preservation effect is solved.

Description

[0001] Technical field [0002] The invention belongs to the integration of solar photovoltaic and building, and in particular relates to a ventilation window of a time-controlled concentrating photovoltaic electrothermal coupling ventilation system in winter. Background technique [0003] With the rapid development of my country's economy, people's focus on the living environment gradually tends to pursue the quality of health and comfort. In winter, if the windows are closed for a long time, the indoor air will become dirty due to lack of circulation, which will affect human health. It is necessary to open the windows for ventilation, and opening the windows, with the inflow of low-temperature air, will not only increase the indoor heating load , causing greater energy consumption and affecting comfort, and if the air is mixed with dust and pollutants, it will still affect human health and cause harm. Especially in northern rural areas, because the heating methods are mostl...

AI Technical Summary

Problems solved by technology

The photovoltaic panel of the ventilation window is located on the upper part of the window. If the waste heat generated cannot be effectively eliminated, the conversion rate of photovoltaic cells will decrease and the battery life will be shortened.

[0010] In order to ensure ventilation without opening windows in winter, and at the same time, to meet the indoor heating load without a substantial increase, the electric energy output by photovoltaic panels and the waste heat generated are fully utilized to solve the ventilation and indoor heat preservation effects of windows in winter incompatibility issue
