Description

[0001] The present invention relates to a method for controlling a building heating /

The present invention relates to a method of controlling a building cooling power load through an indoor temperature control, and more particularly, to a method of controlling a building cooling power load by controlling a room temperature, As a control method for minimizing the maximum value of the power load of the cooling system due to load or cooling load, it is possible to continuously improve the indoor temperature set value within the comfortable temperature range, thereby greatly improving the satisfaction of the indoor warm and cool comfort, The present invention relates to a method of controlling a building cooling power load through an indoor temperature control that can eliminate a resident's dissatisfaction with the control and thereby exclude a resident's continuous participation in the demand management program.

Peak power demand in the power grid is generated by cooling demand in summer, and demand for heating power in winter accounts for a large proportion.

Current methods for managing such peak power demand are as follows.

(1) A system that blocks the power of some power equipment so that the peak power of the building is not exceeded by installing the maximum demand management controller (DC) on the customer's building.

(2) A method in which a power company directly operates the cooling system of the customer and cyclically controls stopping and starting.

(3) a method by which the customer participates in the autonomous power saving system and reduces his / her own power load at peak time.

In particular, the technical method of managing the cooling load power of a building in a power load is as follows.

(1) A method of periodically controlling the operation of the outdoor unit on-off.

(2) Cooling system A method of continuously controlling the compressor operation load ratio of the outdoor unit through inverter control.

(3) Partitioning or periodic on-off control of the number of units that are operated and stopped for indoor / outdoor air conditioning / air-conditioning equipment.

(4) a method of adjusting the indoor temperature of the building.

However, due to the inevitable result that the room temperature increases in the cooling and the room temperature decreases in the heating due to the power load control operation focused on the purpose of reducing the cooling and heating power, the satisfaction of the degree of comfort of the room temperature Can be greatly reduced, and the residents' complaints about the heating / cooling control can accumulate, thereby causing a problem that the resident's participation in the demand management program is hindered.
