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

Abstract

The invention discloses an air-conditioning load adjustment system and an air-conditioning load adjustment method. The air-conditioning load adjustment system is set in a building with air-conditioning equipment, including: an air-conditioning load forecasting unit, which calculates the future time interval of the air-conditioning equipment according to the data of the past time interval The forecasted load; the indoor temperature and humidity sensing module, which senses the temperature and humidity of the building at the first time; the wind speed sensing module, which senses the wind speed of the air-conditioning equipment at the first time; The wind speed calculates the comfort level that the air-conditioning equipment needs to achieve in the second time; the energy management platform controls the central monitoring computer according to the comfort level to generate the temperature setting value and wind speed setting value of the air-conditioning equipment. The central monitoring computer compares the predicted load with the actual load of the air-conditioning equipment when the air-conditioning equipment is running, and corrects the temperature setting value and wind speed setting value according to the comparison result. The invention can achieve the purpose of saving energy and reducing power consumption in peak hours.

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...

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
