An energy-saving building HVAC system

Abstract

The invention discloses an energy-saving building HVAC system, comprising a floor detection unit, an 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 filter unit, and a harmful gas detection unit. Unit, natural wind ventilation control host, floor main ventilation duct delivery module, floor ventilation branch duct opening and closing module, floor ventilation branch duct delivery module, temperature analysis control module, active temperature regulation unit, cold source equipment, heat source equipment, floor information Acquisition unit, human flow detection module, human flow analysis module, area division module, wind direction control host, and air conditioner outlet direction reversal module. The air temperature adjustment required by different areas is analyzed through the human flow analysis module, and then the air volume is divided into different areas by the area division module, thereby reducing unnecessary HVAC air output and achieving energy-saving effects.

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...

Problems solved by technology

[0003] Existing building HVAC is mostly a single delivery of HVAC gas into the building. Due to the different room spaces in the building, it leads to uneven cooling and heating in different indoor areas, which makes the human body feel different. When people move in areas beyond the body temperature, they need Increase the cooling and heat of HVAC to adjust to achieve the comfort range of the body. This will cause the cold and heat in other areas to be higher than the required cooling and heat, which will cause a certain amount of energy waste and not enough energy. Therefore, an energy-saving building HVAC system is proposed.
