Low-energy-consumption multi-area refined variable-air-volume air conditioning system and control method thereof

Abstract

The invention discloses a low-energy-consumption multi-area refined variable-air-volume air conditioning system and a control method thereof. The system comprises a first air supply duct, a second airsupply duct, a return air duct and a plurality of areas, wherein the first air supply duct is connected with one ends of the plurality of areas through a first air supply branch pipe, the second airsupply duct is connected with one ends of the plurality of areas through a second air supply branch pipe, and the other ends of the plurality of areas are connected with the return air duct, one end,far away from the plurality of areas, of the first air supply duct is sequentially provided with an independent ventilation unit, a first surface cooler, a first filter and a first ventilation valve,the first surface cooler is connected with a first electric valve, the first electric valve is connected with one end, far away from the independent ventilation unit, of the first air supply duct through a first controller, the independent ventilation unit is connected with a first frequency converter, and the first frequency converter is connected with one end, far away from the independent ventilation unit, of the first air supply duct through a second controller. The low-energy-consumption multi-area refined variable-air-volume air conditioning system and the control method thereof have theadvantages of being accurate in control, convenient to use and good in effect.

Description

technical field [0001] The invention relates to the field of building ventilation and air-conditioning, in particular to a low-energy-consumption multi-area refined variable air volume air-conditioning system and a control method thereof. Background technique [0002] With the rapid development of my country's economy and the improvement of people's living standards, people's requirements for indoor environment are getting higher and higher. However, creating a high-demand indoor environment requires a certain amount of energy consumption. According to incomplete statistics, my country's building energy consumption has reached about 29% of the total energy consumption. The energy consumption of the air conditioning system accounts for 25%-50% of the energy consumption of the entire building. However, under normal circumstances, a comfortable indoor thermal environment means that more energy consumption is required, and people often sacrifice comfort at the expense of energy...

AI Technical Summary

Problems solved by technology

In actual engineering, in the existing large public buildings, most of the air-conditioning variable air volume systems have insufficient fresh air supply, uneven distribution of air volume, low level of refined air supply in each area, and high energy consumption.
