Embodiment Construction

[0063] The current central air-conditioning terminals (the central air-conditioning terminals in this application plan include fresh air intake devices and ventilation devices installed in the terminal boxes), all of which are controlled by the on-site staff by controlling the working status of the fan coil units. Although the above-mentioned control method is simple to control the temperature in the room, it is not controlled according to the actual situation in the room, which often results in waste of air-conditioning energy consumption. At present, the terminal control of central air-conditioning usually only has self-feedback control of temperature, which cannot intelligently adjust the operating parameters of the central air-conditioning terminal in combination with indoor conditions or indoor conditions within a set time in the future, and each air-conditioning area does not interfere with each other. , did not make full use of the mutual coldness or heat. Above-mention...

Abstract

The invention discloses an intelligent central air conditioner energy-saving control method and system. The method comprises the following steps that based on environment conditions of each air conditioner area of an air conditioner terminal, temperature-air volume indexes for maintaining the lowest power consumption operation of each air conditioner area are calculated and stored; an air change time table corresponding to each air conditioner area is built and stored, and the fresh air margin of the air conditioner areas is estimated according to the time difference value between the currenttime and the last air change time and the environment conditions of the air conditioner areas; the temperature and set type gas content information at the current time in the air conditioner areas aredetected; the staff density in the air conditioner areas is automatically detected or determined based on user input; and the cold quantity / heat quantity, air change frequency and fresh air volume needed at present in the air conditioner areas are calculated, and the air conditioner terminal equipment is controlled to act. The parameters such as the fresh air volume are determined by detecting the staff number in the air conditioner areas and associated with the per capita heat / cold load and the per capita fresh air volume, the air conditioner areas are prevented from working with full load when not in use, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of air-conditioning control, more specifically, it relates to an intelligent central air-conditioning energy-saving control method and system. Background technique [0002] The refrigeration mechanism and heating mechanism of the central air conditioner are concentrated in one place, and the air duct air supply method is adopted, and the temperature of multiple rooms can be controlled with one host, and the central air conditioner with a fresh air system can also introduce fresh air, which can effectively improve Indoor air quality. At present, central air conditioners are widely used in shopping malls, complex buildings and other buildings, which can adjust the local temperature and air flow inside the building. [0003] The operating energy consumption of central air-conditioning mainly comes from the operation of hot and cold water units, the use of compressor pumps and the use of air-conditioning termin...
