Content of the Utility Model
[0005] The purpose of the utility model is to solve the problem that although the initial attempts of traditional buildings in solar energy utilization have achieved some results, in the face of the increasingly severe energy crisis and environmental challenges, their limitations are becoming more and more prominent. The low-efficiency energy conversion and the insufficient integration of house design and solar energy utilization lead to the difficulty in fully guaranteeing the livable effect of low-carbon houses, and a low-carbon house with solar energy frequency division utilization is proposed.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A low-carbon house for solar energy frequency division utilization, comprising a low-carbon house and a grid-connected power generation system. On the roof of the low-carbon house, there are solar photovoltaic modules and high-thermal-conductivity multi-layer composite heat collection elements. Inside the low-carbon house, there is also a multi-functional sunny indoor green plant leisure hall. Outside the multi-functional sunny indoor green plant leisure hall, there are laid light-transmitting solar photovoltaic modules. Inside the low-carbon house, there are also an intelligent ground source heat pump system, a temperature and humidity precision control air conditioner, an indoor light array light strip module and a dynamic heat circulation water heater.

Outside the low-carbon house, there is an outdoor self-adjusting optical fiber lighting system. The grid-connected power generation system is electrically connected to the solar cell module. On the wall of the multi-functional sunny indoor green plant leisure hall, there is a heat insulation layer, which can reduce the heat loss inside the house in cold weather and provide a leisure area with a suitable temperature.
[0008] The solar photovoltaic module continuously provides clean electricity for the house. The excess electricity can be automatically connected to the grid-connected power generation system and is connected to the dynamic heat circulation water heater through a degradable water supply pipe together with the high-thermal-conductivity multi-layer composite heat collection element to provide domestic hot water for the low-carbon house.
[0009] A multi-functional sunny indoor green plant leisure hall. The multi-functional sunny indoor green plant leisure hall adopts an innovative bookshelf-style green plant layout. The plants improve the indoor air quality through photosynthesis. Inside, there is an environmental protection heat insulation layer to keep the environmental temperature suitable and provide a comfortable indoor leisure area. Outside, there is a light-transmitting solar photovoltaic module for solar energy frequency division utilization;
[0010] The light-transmitting solar photovoltaic module for solar energy frequency division utilization outside the multi-functional sunny indoor green plant leisure hall. The light-transmitting solar photovoltaic module is a light-transmitting solar cell that does not absorb the light in the wavelength bands necessary for plant growth.
[0011] An intelligent ground source heat pump system.

[0012] The outdoor self-adjusting optical fiber lighting system adopts optical fiber light guiding technology and integrates high-brightness and low-power consumption LED chips and intelligent dimming circuits with the indoor light array light strip module to achieve green intelligent lighting.
[0013] Through the above technical solutions, the present utility model designs a low-carbon house for solar energy frequency division utilization. By adopting a variety of high-efficiency energy-saving technologies and green ecological elements, it more efficiently utilizes solar energy resources, reduces the dependence on traditional energy, and at the same time improves the living comfort and building energy efficiency level. In the low-carbon house designed by the present utility model, the high-efficiency solar photovoltaic modules not only continuously provide electric energy for the low-carbon house, but also provide heat energy for the dynamic thermal circulation water heater. The multi-functional indoor green plant leisure hall on the sunny side has a light-transmitting solar photovoltaic module for frequency division utilization of solar energy, which promotes plant photosynthesis and improves the indoor air quality. In addition, the intelligent ground source heat pump system in this design is linked with the temperature and humidity precision control air conditioner and the dynamic thermal circulation water heater to ensure a constant temperature and humidity throughout the year in the house and provide domestic hot water. The self-adjusting optical fiber lighting system outside the house and the light array light strip module inside the house provide diversified lighting options, significantly improving the living comfort.
[0014] In a possible design, the solar photovoltaic module is a high-efficiency photovoltaic building integrated crystalline silicon solar cell. The low-carbon house faces south and north, and the roof is triangular. The high-efficiency photovoltaic building integrated crystalline silicon module not only coordinates with the building materials in appearance, adding beauty to the house, but also can provide sufficient power supply for the house, and the excess power can be automatically connected to the grid-connected power generation system.
[0015] In a possible design, a high-thermal conductivity multi-layer composite heat collection element is also configured near the solar photovoltaic module, which can effectively absorb and collect the waste heat generated during the high-efficiency power generation process of the solar photovoltaic module, heat the water and transport it to the dynamic thermal circulation water heater.
[0016] In a possible design, the multi-functional indoor green plant leisure hall on the sunny side adopts an innovative bookshelf-style green plant layout.
[0017] In a possible design, the indoor green plant hall has an environmental protection heat insulation layer that can effectively prevent the heat transfer between the inside and outside of the house in cold weather, keep the indoor temperature stable, and provide a comfortable leisure area.
[0018] In a possible design, the light-transmitting solar photovoltaic module is a semi-transparent perovskite solar cell with unique spectral selectivity, which only absorbs light in the wavelength range of 500 - 630 nm. This not only ensures the effective conversion between solar energy and electric energy, but also cleverly avoids the key spectral regions necessary for plant growth. The light-transmitting solar cell that does not absorb the light in the wavelength range necessary for plant growth or the photovoltaic module with a light transmittance of more than 60% - 80% promotes plant photosynthesis to improve the indoor air quality.
[0019] In a possible design, the intelligent ground source heat pump system has a control system with components such as valves and microcircuits, and is linked with the temperature and humidity precision control air conditioner on the north side of the house to achieve a constant temperature and humidity inside the house and improve the living comfort.
[0020] In a possible design, the dynamic thermal cycling water heater supports temperature presetting, and is connected to a high-thermal-conductivity multi-layer composite heat collection element and an intelligent geothermal heat pump system through a degradable water pipe. After the water is preheated by the high-thermal-conductivity multi-layer composite heat collection element, it is transmitted back to the dynamic thermal cycling water heater. When the water temperature does not reach the set temperature, it is supplemented and heated to the preset value by the intelligent geothermal heat pump system and then cyclically transmitted back to the dynamic thermal cycling water heater.
[0021] In a possible design, the outdoor self-adjusting optical fiber lighting system and the indoor light array light strip module are energy-saving and efficient, providing diversified lighting options and being more beautiful.
