Air-conditioning load adjusting system and air-conditioning load adjusting method

Abstract

The invention discloses an air-conditioning load adjusting system and an air-conditioning load adjusting method, the air-conditioning load adjusting system is arranged in a building with air-conditioning equipment, and comprises an air-conditioning load prediction unit for calculating the predicted load capacity of the air-conditioning equipment in a future time interval according to the data of apast time interval; an indoor temperature and humidity sensing module which is used for sensing the temperature and humidity of the building at the first time; an air speed sensing module which is used for sensing the air speed of the air conditioning equipment at the first time; a comfort prediction module which is used for calculating the comfort required to be achieved by the air conditioningequipment at the second time according to the temperature, humidity and wind speed; and an energy management platform which controls the central monitoring computer to generate a temperature set valueand a wind speed set value of the air conditioning equipment according to the comfort level. And the central monitoring computer compares the predicted load capacity with the actual load capacity ofthe air conditioning equipment when the air conditioning equipment operates, and corrects the temperature set value and the wind speed set value according to the comparison result. According to the invention, the purposes of saving energy and reducing the power consumption in the peak period can be achieved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an adjustment system and an adjustment method for adjusting air conditioner loads. Background technique [0002] Large-scale air-conditioning systems are usually equipped with corresponding ice water hosts. These ice water hosts will perform ice-making procedures during off-peak hours when electricity costs are cheaper, while air-conditioning systems can use pre-made ice cubes during peak hours when electricity costs are more expensive. Heat exchange, thereby reducing the cost of electricity required for the air conditioning system. [0003] The ice making program of the ice water host generally has a fixed ice storage volume. However, internal factors (such as the number of people or activities) and external factors (such as temperature or humidity) that affect the comfort in a building vary from day to day. Keeping the room at a constant comfort level in each time period may c...

AI Technical Summary

Problems solved by technology

However, at this time, the ice-making process may consume high electricity bills during peak hours, and the extra electricity consumption may cause the overall electricity consumption of the air-conditioning system to exceed the contracted capacity

[0005] Furthermore, when the indoor environment changes drastically (such as sudden heat), the air-conditioning system will need to drive the chiller unit to run violently to quickly improve the environment, causing the chiller unit to exceed the optimal efficiency range of 60% to 80%. , which will also increase the overall power consumption of the air conditioning system
