Embodiment Construction

[0011] Hereinafter, description will be given in detail of preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

[0012] As shown in FIG. 1, the demand control system for multiple air conditioners according to the present invention may include: a wattage consumption sensing unit 10 for calculating estimated wattages consumed by a plurality of air conditioners 50 in a building; and demand control A unit 20, configured to control the demand control unit by changing the operation mode of at least one air conditioner 50 among the plurality of air conditioners when the wattage consumption sensing unit notifies the demand control unit that the estimated wattage consumption exceeds a set wattage value. The operating efficiency of the air conditioner 50.

[0013] Each of the plurality of air conditioners 50 may include an outdoor unit 51 and at least one indoor unit 52 connected to the outdoor unit 51 .

[0014] The wattage c...

Abstract

A demand control system for the multi-type air conditioner includes a demand control unit for controlling the operational efficiency of the air conditioners by changing the operation mode of the air conditioners when the estimated wattage exceeds a set wattage while enabling the user to feel more comfortable.

Description

technical field [0001] The present invention relates to a demand control system and method for a multi-type air conditioner. Background technique [0002] Generally, the demand control mechanism of the multi-type air conditioner is to control the consumption of electric power by starting / cutting off the air conditioner randomly selected or selected among multiple air conditioners according to the preset cycle, so as to control the operating efficiency of the multi-type air conditioner to an allowable The wattage (that is, the amount of electric power) range. [0003] The demand control mechanism emphasizes electric power control rather than user's convenience, and limits power consumption by continuously cutting off consuming loads of electric power. [0004] However, the prior art demand control system of the multi air conditioner has the following problems. That is, since the air conditioner to be supplied with or cut off the electric power supply is selected without con...
