Abstract

The invention discloses a control method and system for air supply of an air conditioner. The method includes the steps that the initial overall indoor people number is measured according to the concentration of indoor and outdoor carbon dioxide; a closed circuit television system is adopted for measuring the real-time overall indoor people number and the real-time people numbers of multiple indoor regions; according to the initial overall indoor people number, the real-time overall indoor people number and the real-time people numbers of the indoor regions, the fresh air amount required indoors is measured; and according to the fresh air amount, the air conditioner is controlled to supply air. The method and system have the beneficial effects that the indoor people distribution condition is accurately measured, the real-time fresh air supply amount of a central air-conditioning fresh air system can be adjusted in real time, the central air-conditioning energy saving effect can be achieved, and the good quality of indoor air is maintained.

Description

technical field [0001] The present invention relates to an air-conditioning air supply control system, more specifically, to a control method and system for air-conditioning air supply. Background technique [0002] In 2014, the total energy consumption of buildings exceeded 1.25 billion tons of standard coal, accounting for 30% of the total energy consumption of the society; the energy consumption of central air-conditioning accounted for 65% of the total energy consumption of buildings, and the energy consumption of refrigeration stations accounted for about 70% of the energy consumption of air-conditioning systems; Especially in hot and humid southern regions, because the outdoor relative humidity (RH) is too high (often above 80% to 90%), the energy consumption of the central air-conditioning system to deal with outdoor fresh air even exceeds 50%. Since the quality of indoor air directly affects the health of indoor personnel, in order to create a healthy and comfortable...
