Abstract

The invention discloses an energy-saving central ventilation system which comprises an air outlet device for pumping indoor air to an outdoor place, an air inlet device for pumping outdoor air into an indoor place after the outdoor air is filtered and a power device used for providing electric energy. The power device comprises a solar photovoltaic assembly, an MPPT controller, a storage battery and an inverter; the output end of the solar photovoltaic assembly is connected with the input end of the MPPT controller, the output end of the MPPT controller is connected with the input end of the storage battery, the output end of the storage battery is connected with the input end of the inverter, and the two output ends of the inverter are connected with the air outlet device and the power input end of the air outlet device; and the solar photovoltaic assembly can convert optical energy into the electric energy and stores the electric energy into the storage battery, the inverter converts the generated direct current electric energy into alternating current and outputs the alternating current to the air outlet device and the air inlet device for use, and therefore solar energy is applied to the central ventilation system, and energy saving and environmental protection are better achieved.

Description

technical field [0001] The invention relates to the field of ventilation, in particular to an energy-saving fresh air system. Background technique [0002] In recent years, the problem of environmental pollution has become more and more serious. The frequency of smog and sandstorms in some cities has become more and more frequent, which has brought great threats to people's health. In order to prevent the harm caused by air pollution to human health , people have taken various measures, such as installing fresh air systems. The fresh air system is a ventilation system that satisfies the indoor fresh air supply. It generally includes an air outlet device for drawing indoor air to the outside, an air inlet device for filtering the outdoor air and drawing it indoors, and a power supply for providing electrical energy. , the power supply generally adopts the mains. While the fresh air system has achieved results, there are still some shortcomings. At present, the global green...
