The invention discloses a heat pump type solution humidity-adjusting air treatment device, which belongs to the technical field of air humidity control, and comprises a housing assembly, a pressure assembly, and a heating assembly. One end of the assembly is provided with a pressure assembly, and one end of the pressure assembly is provided with a heating assembly. The invention is scientific and reasonable, and safe and convenient to use. control effect, making the room warm in winter and cool in summer. This device increases the content of negative oxygen ions in the exhausted air and guides them into the room. On the basis of achieving the indoor cooling or heating effect, the participation of negative oxygen ions is also beneficial to human health. The device makes full use of the condensed water generated, and mixes the condensed water with the air containing negative oxygen ions, so that the water vapor entering the room can be distributed more evenly, effectively avoiding the uneven distribution of moisture concentration.

The air quality control system of the present invention is a convenient and practical indoor air quality, temperature and humidity monitoring and adjustment system that is reasonable in design, energy saving and consumption reducing, compact in structure, maintains indoor micro-positive pressure, and can effectively solve the problems existing in the prior art .

The invention relates to a fiber cement board. The fiber cement board includes a surface layer and a structure layer, wherein the structure layer is prepared from, by mass, 25-45% of cement, 10-30% of silica sand, 10-25% of lightweight aggregate, 0.1-0.8% of water reducing agent, 2-6% of fiber, 1-5% of adhesive and 10-18% of water. The fiber cement board has good mechanical performance and high strength, does not crack, is free of cracks, meanwhile has good processing and decorative performance and can undertake after processing such as grinding to obtain a smooth surface, sand blasting to form a sandy surface or pickling to form an acid washing surface, and a variety of different decorative effects are obtained. In addition, the fiber cement board has a negative oxygen ion function, can significantly improve the air quality and increase the air negative oxygen ion content, can improve a body immune function and can improve sleep, improve a lung function, soften blood vessels and other health functions. The board is named as a pharaoh stone.

The invention belongs to the technical field of teaching devices, specifically a teaching device based on big data, including a desktop; table legs are fixedly installed on the lower surface of the desktop; a placement groove is opened on the upper surface of the desktop, and A touch screen is fixedly installed in the placing groove; a placing plate is fixedly installed on the lower surface of the desktop; a space 1 is formed between the placing plate and the desktop; a closed plate is fixedly installed in the space 1; the closed plate, placed A space two is formed between the board and the desktop; a controller is fixedly installed in the space two; the touch screen is electrically connected to the controller; the present invention has simple structure, low production cost, and can clean the surface of the teaching device after use , to prevent the growth of germs, and at the same time, during the use process, negative oxygen ions are generated and diffused near the students, which can improve the spirit of the students, make the students concentrate, and improve the learning efficiency.

The invention discloses an energy-saving disaster-prevention central air conditioner system. In the energy-saving disaster-prevention central air conditioner system, a geothermal energy collector is arranged between a building and a green belt; a main body is a closed underground water storage tank excavated in a shallow layer below a ground surface; the upside of the underground water storage tank is communicated with the outside through a rainwater collecting hole arranged on the ground surface; an inner cavity of the underground water storage tank contains rainwater; an energy exchanger is a coil pipe arranged in the inner cavity of the underground water storage tank; the coil pipe is soaked in water, and two ends of the coil pipe are respectively communicated with an air outlet pipeline and an air inlet pipeline; an air inlet is connected to the tail end of the air inlet pipeline, and the air inlet and the air inlet pipeline are both arranged in the green belt far away from the building; and an air outlet is connected to the tail end of the air outlet pipeline, and the air outlet and the air outlet pipeline are respectively arranged in terminal user rooms in the building. According to the energy-saving disaster-prevention central air conditioner system disclosed by the invention, fresh air after temperature adjustment can be provided for terminal users in the building, and the fresh air far away from a fire scene can be fed to the terminal users in the building in case of fire, so that the energy-saving disaster-prevention central air conditioner system has the characteristics of energy conservation and environmental friendliness.
