High-heat-preservation-property solar drying room

Abstract

The invention discloses a high-heat-preservation-property solar drying room comprising a room frame, walls and light-transmitting heat-insulation plates on the ceiling. The walls are fixed to the room frame and form the drying room. The inner side faces of the light-transmitting heat-insulation plates are coated with a light absorbing material so that sunlight transmitting the light-transmitting heat-insulation plates can be converted to heat, and the heat is evenly distributed into the room directly. Meanwhile, a controllable exhaust opening is formed in the ceiling. A ceramic solar panel is arranged in the drying room, heat converted from solar energy is directly distributed into the room in a thermal radiation mode, the heating effect is optimized, and therefore the drying room is more similar to an existing drying environment; besides, because the ceramic solar panel has good photo-thermal conversion performance and heat-conducting property, it can be guaranteed that the temperatures at all the positions are basically identical, and the even heating effect is achieved; light-transmitting heat-insulation glass and outside heat preservation room design are adopted, and the double heat preservation effect can guarantee the continuous drying effect at night.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to a high thermal insulation solar drying room. Background technique [0002] At present, my country generally attaches great importance to the development of solar water heater products, but there are not many products for comprehensive utilization of solar heat and light. [0003] Chinese patent CN103162428 discloses a solar hot air drying and heating device, which is mainly composed of double-layer light-transmitting heat-insulating glass, heat-absorbing material coating, aluminum alloy box frame, insulating material layer, solar photovoltaic panels, micro-fans and other components . Among them, the double-layer light-transmitting heat-insulating glass transmits light but does not conduct heat, and the heat-absorbing material is sprayed on the inner surface of the aluminum alloy box frame and the heat-insulating material layer. [0004] Although the above-mentioned patents effec...

Problems solved by technology

[0004] Although the above patents effectively use solar energy for drying, the use of thermal insulation materials in the house limits the speed of heat transmission. It can only be transmitted through air flow, which increases the use of electricity and limits the drying temperature and effect.
