An occupancy detection apparatus and a method for controlling the same are disclosed. The occupancy detection apparatus may include a transmitter including one transmission antenna for outputting a transmission signal, a receiver including a first reception antenna and a second reception antenna, each for receiving a reflected signal corresponding to the transmission signal, and a processor for eliminating a background signal corresponding to a background from each of the reflected signals, and extracting a signal reflected from an occupant from each of the reflected signals by extracting a correlation between the transmission signal and the reflected signal free of the background signal.

Occupancy detection apparatus and method for controlling the same

This specification relates to a central control apparatus, which is configured to calculate time-division power usage as predicted power usage, which is consumed by at least one facility in a control area within a specific time section, on the basis of predicted external temperature corresponding to the control area within the specific time section and a time-division model, calculate variable-based degree day (VBDD) daily power usage as predicted daily power usage corresponding to the control area on the basis of the predicted external temperature and a VBDD model, and calculate final power usage as final predicted power usage consumed in the control area within the specific time section on the basis of the time-division power usage and the VBDD daily power usage, and a facility control system including the same.

Central control apparatus for controlling facilities and facility control system having the same

Disclosed are a central control system and a method for setting a control point thereof. A central controller or a control point generator generates a control map in which control points are indicated, and the control points and attribute data of devices such as indoor units on the spot in actuality are automatically matched through a mobile terminal. Also, attribute data required for setting a control point is made into a database by using a dedicated tool such as the central controller or the control point generator, thus automatically setting control points. Also, the central control system can be installed by setting attribute data of the respective control points by using a wireless solution such as a mobile terminal, without having technical knowledge.

Central control system and method for setting control point thereof

A test-operation control apparatus, system and method are disclosed to reduce time and cost required for test operation by automatically performing test-operation on a control point of facilities installed on site based on a previously established template sequence and operational conditions of the situation on the spot. The test-operation control apparatus includes: a storage unit configured to store a basic sequence with respect to each of one or more control points set in the facilities installed on the spot (or site); an input unit configured to selectively receive one or more of the control points and receive operational conditions of each basic sequence with respect to each of the one or more of the selected control points; and a controller configured to combine the basic sequences with respect to each of the one or more of the selected control points according to the inputted operational conditions to generate a test-operation sequence.

Test-operation control apparatus, system, and method

A system and method for controlling one or more facilities based on one or more operation logic parameters is provided. An operation scenario is generated, taking into consideration actual operation of one or more facilities of a particular system, actual control orders, a time interval between data inputs, and other such factors. Operation logic parameters, or algorithms, are then tested based on the generated operation scenario. This system and method may reduce testing time and costs, and may prevent abnormal operation of the facilities of the system.

Facilities control system and operating method of the same

A communication apparatus, an air conditioning system having the same, and a communication method for the air conditioning system using a refrigerant pipe are provided. The refrigerant pipe may be used as a transmission line to allow communications between an outdoor unit and an indoor unit, and a low frequency band signal and a core having an inductance value appropriate for the characteristic of a pipe communication frequency may be used to perform the pipe communication, which allows communications between the outdoor unit and the indoor unit without a separate communication line, resulting in minimizing noise interruption and affection of surge, and avoiding signal strength attenuation and signal radiation.

Communication apparatus, air conditioning system having the same and communication method thereof using refrigerant pipes

In an air conditioning system and a communication method thereof a wireless network may be established between indoor units and a controller or between outdoor units so as to allow communications therebetween, thereby facilitating device addition or device deletion. Also, one or more outdoor units and a plurality of indoor units may be controlled without a dedicated communication line or with using a less mount of the dedicated communication line, and the outdoor units or indoor units may perform communications using one or more communication technologies, such as wireless communication and pipe communication technologies and wireless communication and dedicated line communication technologies, while performing communications with the controller using the wireless communication technology.

Air conditioning system and communication method thereof

An air conditioning system includes a plurality of indoor units and one or more outdoor units to drive the indoor units. The one or more outdoor units are coupled to the indoor units through refrigerant pipes that include one or more branch points. A calculator calculates an amount of filling refrigerant based on capacities of the indoor units and the one or more outdoor units and lengths of the refrigerant pipes.
