Electric power engineering
Solar power generation relies on the photovoltaic effect: When sunlight strikes a solar panel (made of semiconductor materials), electrons within the panel are activated, generating direct current (DC). This DC power is then converted through an inverter into alternating current (AC) for use in homes, businesses, and factories. Excess electricity can be stored in batteries or fed into the public grid for profit. The entire process is emission-free and noise-free, relying entirely on renewable energy like sunlight—a truly environmentally friendly process!

The key to air-conversion energy-saving projects lies in "efficient ventilation + heat recovery." Through a heat exchange core, the system allows fresh air to enter the room and contaminated air to exit, exchanging heat between the two air streams. For example, in summer, the warm outdoor air absorbs heat from the cool exhaust air, pre-cooling it before being drawn into the room. In winter, the reverse occurs: the cool outdoor air absorbs heat from the warm indoor air, pre-heating it. This eliminates the need for the air conditioning system to repeatedly heat and cool the fresh air, reducing energy consumption. This, like "retaining heat/cold" during indoor ventilation, ensures fresh air while lowering electricity costs.

The working principle of an EV charging station is simple: the station is connected to the power grid via a dedicated line. An internal charging module converts the grid's AC power into the DC power required by the EV battery. Simultaneously, a control unit monitors the battery status (e.g., charge level and voltage) and automatically adjusts the charging current and voltage to ensure safe and stable charging. Just like charging a mobile phone, when an EV is plugged in, the station intelligently supplies power based on the vehicle's needs and automatically shuts off when fully charged, eliminating the need for human oversight.
