Embodiment 1

[0042] see figure 2 , in the heating season, open the indoor upper ventilation baffle D3 and the indoor lower ventilation baffle D2, so that the indoor upper ventilation opening V3 and the indoor lower ventilation opening V2 are in the open state, and close the outdoor ventilation baffle D1, so that the outdoor ventilation opening V1 is closed State; close cold water inlet 9 and hot water outlet 10. Sunlight shines on the photovoltaic module 3 through the glass cover plate 1, and the sunlight is used to generate electricity to supply electricity for the building, and the remaining solar radiation heat is heated and adsorbed under the action of the heat-absorbing plate-thermocatalytic coating 6 to 60 to 80 °C, reaching the start-up temperature of the thermocatalytic material to achieve air purification; at the same time, the indoor cold air enters the air channel 7 of the system through the indoor lower vent V2, and the air in the air channel is heated by the adsorption-thermo...

Embodiment 2

[0044] see image 3 , in the non-heating season, open the indoor lower ventilation damper D2 and the outdoor ventilation damper D1, so that the indoor lower ventilation opening V3 and the outdoor ventilation opening V1 are in the open state, and close the indoor upper ventilation damper D3, so that the indoor upper ventilation opening V1 is in the open state. Closed state; open cold water inlet 9 and hot water outlet 10. The sunlight shines on the photovoltaic module 3 through the glass cover plate 1. The sunlight is used to generate electricity to supply electricity for the building, and part of the remaining solar radiation heat is used to heat the water pipe 4 to obtain hot water. The temperature of the hot water is about 50-80°C. It can meet the needs of domestic hot water, and at the same time cool down the photovoltaic module through water pipes to improve the power generation efficiency of the photovoltaic module; the other part of the remaining heat heats the heat abso...

Abstract

The invention discloses a catalytic purification-sterilization disinfection type multifunctional photovolatic passive ventilation wall. Different modes are switched by controlling opening and closingof baffles at all ventilation openings. The ventilation baffles comprise an outdoor ventilation baffle (D1), an indoor lower ventilation baffle (D2) and an indoor upper ventilation baffle (D3). The ventilation openings comprise an outdoor ventilation opening (V1), an indoor lower ventilation opening (V2) and an indoor upper ventilation opening (V3). The back face of a heat absorption plate (5) issprayed with an adsorption-thermal catalysis coating. According to the catalytic purification-sterilization disinfection type multifunctional photovolatic passive ventilation wall, the thermal catalysis technology, the thermal sterilization disinfection technology and the solar photovolatic photo-thermal technology are innovatively combined and utilized, the functions of power generation in the heating season, passive heating ventilation, air purification and thermal sterilization disinfection can be achieved, and the functions of power generation in the non-heating season, domestic hot waterpreparation, passive cooling, purification and thermal sterilization disinfection are achieved; and in the transition season, according to the building requirements, the functions of domestic hot water preparation and passive heating can be flexibly achieved by adjusting the ventilation baffles while power generation, thermal catalytic degradation of formaldehyde and thermal sterilization disinfection are conducted.

Description

technical field [0001] The invention belongs to the field of solar energy utilization and building environment control, and specifically relates to a catalytic purification-sterilization and anti-virus multifunctional photovoltaic passive ventilation wall. Background technique [0002] On the one hand, the main forms of combining solar energy utilization with buildings include: Building Integrated Photovoltaic (BIPV), Building Integrated Photothermal (BIST) and Building Integrated Photovoltaic Thermal (BIPV-T). Among them, building-integrated photovoltaics and building-integrated photothermal technologies have problems such as single function, poor adjustability, high cost, and low comprehensive utilization efficiency of solar energy. In the photovoltaic-thermal building-integrated technology, for the photovoltaic-hot air mode, the heat collection function is idle in non-heating seasons, and high temperature will significantly affect the power generation efficiency and servi...
