Energy-saving building heating and ventilation system

Abstract

The invention discloses an energy-saving building heating and ventilation system. The energy-saving building heating and ventilation system comprises a floor detection unit, a floor external environment detection unit, a natural wind conveying opening and closing control unit, an outdoor air quality detection unit, an indoor air quality detection unit, an air filtering unit, a harmful gas detection unit, a natural wind ventilation control main machine, a floor main ventilation pipeline conveying module and a floor ventilation branch pipeline opening and closing module, a floor ventilation branch pipeline conveying module, a temperature analysis control module, an active temperature adjustment unit, cold source equipment, heat source equipment, an in-floor information acquisition unit, a pedestrian flow detection module, a pedestrian flow analysis module, an area division module, a wind direction control main machine and an air conditioner air outlet direction turning module. The air temperature adjustment amounts required by different areas are analyzed through the pedestrian flow analysis module, and then the area division module carries out division on the air outlet amounts of the different areas, so that the unnecessary heating and ventilation air outlet amounts are reduced, and the energy-saving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of heating and ventilation, in particular to an energy-saving building heating and ventilation system. Background technique [0002] "HVAC" is the name of a classification of work in construction equipment. HVAC includes three aspects: heating, ventilation, and air conditioning. These three aspects are referred to as HVAC. Heating is a general term for technologies, equipment, and services that use artificial methods to supply heat to the room by consuming a certain amount of energy to keep the room at the temperature required for life or work. The heating system consists of three main parts: heat medium preparation (heat source), heat medium transportation and heat medium utilization (radiation equipment). Ventilation, to improve the indoor air environment by means of ventilation. Air conditioning, creating an air environment that meets the needs of human production, life and scientific experiments is th...
