Benefits of technology

[0007]Therefore, the present invention is directed to provide a demand control system and a demand control method for a multi-type air conditioner which is capable of enhancing a user's comfort as well as of stably maintaining an electrical power, resulting from reducing a wattage consumption by controlling an air conditioner with changing an operation mode of the air conditioner when an estimated wattage exceeds a set wattage.

Problems solved by technology

However, the related art demand control system for a multi-type air conditioner has the following problem.
That is, because the air conditioner to be provided or deprived of electrical power supply is selected without regard to the user's convenience, the user in an area where the air conditioner is forcibly controlled is located may feel substantially less comfortable.

Embodiment Construction

[0013]Description will now be given in detail of the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

[0014]As shown in FIG. 1, the demand control system for a multi-type air conditioner in accordance with the present invention may include a wattage consumption sensing unit 10 for calculating an estimated wattage consumed by a plurality of air conditioners 50 of a building; and a demand control unit 20 for controlling an operational efficiency of the air conditioners 50 by changing an operation mode of at least one air conditioner 50 of the plurality of air conditioners 50 when the wattage consumption sensing unit notifies the demand control unit that the estimated wattage consumption exceeds the set wattage value.

[0015]The plurality of air conditioners 50 may each include an outdoor unit 51 and at least one indoor unit 52 connected to the outdoor unit 51.

[0016]The wattage consumption sensing unit 10 may receive data with...

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

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a demand control system and method for a multi-type air conditioner.[0003]2. Description of the Related Art[0004]In general, a demand control regime for a multi-type air conditioner is a technique for controlling the consumption of electrical power by switching on / off an air conditioner randomly selected or selected among a plurality of air conditioners according to a pre-set cycle so as to control the operational efficiency of a multi-type air conditioner within the range of a permissible wattage (i.e., the amount of electrical power).[0005]The demand control regime emphasizes electrical power control rather than a user's convenience, and operates to restrict the power consumption by sequentially switching off consumption loads of the electrical power.[0006]However, the related art demand control system for a multi-type air conditioner has the following problem. That is, because the air...
