A photovoltaic louver semiconductor temperature-controlled energy-saving window

Abstract

The invention discloses a photovoltaic shutter semiconductor temperature-control energy-saving window. The photovoltaic shutter semiconductor temperature-control energy-saving window comprises a photovoltaic shutter assembly, a cooling layer, a double-side air adjustment channel and a double-glass interlayer. The photovoltaic shutter assembly is formed by assembling a series of solar photovoltaic cells according to a shutter mode. The double-side air adjustment channel is composed of a window frame, an air adjustment cavity, a thermoelectric heat pump chip set, a fin cooler and a draught fan. The thermoelectric heat pump chip set is connected with the solar photovoltaic cells through a wire, and a current direction control switch is arranged on the wire. According to the photovoltaic shutter semiconductor temperature-control energy-saving window, solar radiation is converted by photovoltaic shutters into direct-current electricity which is used for driving the thermoelectric heat pump chip set to carry out cooling or heating, heat insulation of a window body is effectively achieved through a thermoelectric heat pump while indoor heat obtained by solar radiation is reduced, the building energy consumption is greatly reduced, and the photovoltaic shutter semiconductor temperature-control energy-saving window has the advantages of being simple and compact in structure and efficient, saving energy and the like.

Description

technical field [0001] The invention belongs to the technical field of building doors and windows, and in particular relates to a photovoltaic louver semiconductor temperature-controlled energy-saving window with the characteristics of thermal insulation and reducing indoor air-conditioning load. Background technique [0002] With the rapid development of the construction industry, the problem of building energy consumption has become an important problem to be solved urgently. According to relevant statistics, building energy consumption accounts for about 30% of total energy consumption, and this proportion will continue to grow with the development of society. In the ever-increasing building energy consumption, the energy consumption of air-conditioning equipment accounts for a large proportion, and the heat transfer of the building envelope is the main factor causing the excessive energy consumption of air-conditioning equipment. Design or modification is of great signi...

Problems solved by technology

First of all, such a design necessarily requires the vacuum window to have absolute airtightness, but since the window structure will cause thermal expansion and contraction stress deformation with the fluctuation of indoor and outdoor temperature, during the long-term use of the vacuum energy-saving window, the window It is difficult to guarantee the airtightness of the

Secondly, ordinary vacuum energy-saving windows increase the thermal resistance of the window by adding a vacuum interlayer, thereby reducing the thermal conductivity of the window. However, in the hot summer, the strong outdoor direct solar radiation and scattered radiation from the sky and the ground will pass through Transparent glass enters the room, increasing the indoor air conditioning load, and the use of ordinary louvers or curtains for shading cannot achieve the purpose of rational use of solar energy

[0004] After a patent search, the Chinese patent authorization announcement number is CN202706840U, and the utility model patent name is: solar sunshade integrated energy-saving window. At the same time, the equipment can use solar light and heat resources to prepare a certain amount of hot water for indoor use, but the safety of this solar collector plate hanging outside the window will not be guaranteed, and the solar sunshade integrated energy-saving window can only Reducing the impact of outdoor direct solar radiation on the interior has no significant effect on reducing the heat conduction of the window itself and the outdoor scattered radiation

[0005] Through the patent search, it is also found that the Chinese patent authorization announcement number is CN203285276U, and the utility model patent name is: air flow energy-saving window. This technology adopts the main structure of double-glazed windows, and an ordinary louver sunshade device is installed between the two layers of glass to block the outdoor direct solar radiation. There is an opening under the inner glass to communicate with the indoor air. Using the buoyancy of the hot air in the double-layer glass cavity, the indoor air can flow upward through the opening under the inner glass to cause air circulation and reduce the impact of the window. Indoor heat transfer, but in principle, the air used to cool the double-glazed window cavity is obtained by cooling the indoor air-conditioning equipment, and the overall device has limited ability to reduce the load of the indoor air-conditioning equipment
