HVAC METHOD AND APPARATUS FOR ENERGY MANAGEMENT OF HEATING VENTILATION AND AIR CONDITIONING SYSTEM

摘要

The present invention provides a method for controlling energy in a Heating, Ventilation, and Air Conditioning (HVAC) system. The energy control method according to the present invention includes a process of determining whether a user is absent in a space used for energy control, and when it is determined that a user is absent, the probability of going out and the length of outing of the user extracted based on previously collected and stored data The process of determining whether to start energy control based on the outing pattern, the process of extracting the user's comfort temperature based on the previously collected and stored data when it is determined that the energy control is to be started, and the pre-stored desired energy saving rate and calculating a setback control start temperature and a setback control start time based on the desired temperature return time, and performing energy control according to the calculated setback control start temperature and setback control start time.
