Figure 3 is a block diagram for explaining a heating and cooling management system according to another embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram for explaining a heating and cooling unit according to an embodiment of the present invention.

Referring to Figure 1, the air-conditioning unit according to the present invention is a device for discharging cold air or hot air for heating and cooling, may be a fan coil unit.

The heating and cooling unit 1 according to the present invention includes an input unit 11, a receiver 12, a transmitter 13, a detector 14, a controller 15, a memory 16, a driver 17, and an output unit ( 18) and the switch 19 can be configured.

The memory 16 stores cooling and heating temperatures. The air conditioning temperature may be input through an input unit 11 installed in the air conditioning unit 1, for example, a keypad or a pad provided in a wireless remote controller (not shown).

Such heating and cooling temperatures may include a desired temperature and a minimum temperature. Here, the desired temperature is the desired cooling or heating temperature set by the user or the manager in the room, and the minimum temperature is the room temperature or the temperature desired by the landlord or device manager to minimize the operation of the air conditioning unit for energy saving. it means. This may include 28 ° C. during summer cooling and 18 ° C. during winter heating, which are indoor cooling and heating temperature limits. The minimum temperature is preferably set in advance to operate in an environment where there is no person in the room or no movement of the person for a certain time. Accordingly, when there is no person in the room or there is no movement of the person for a certain time, it is possible to reduce the consumption of energy by controlling the driving of the drive unit 17 to a minimum temperature other than the desired temperature.

The receiving unit 12 receives a control signal from the outside, for example, a control signal for controlling an air conditioner (for example, a drive control signal, a stop control signal, a control signal including a desired temperature, a control signal including a minimum temperature), and the like. can do. In this case, the receiver 12 provides the received control signal to the controller 15.

The outside may be a central control unit (not shown) that integrally manages air conditioning units installed in each room of a building, but is not necessarily limited thereto, and may be a wireless remote controller that independently manages air conditioning units per room. At this time, the central control unit can communicate with the air-conditioning unit installed in each room through a wired or wireless communication method to send a control signal to the air-conditioning unit installed in each room or receive the driving status information of the air-conditioning unit.

The transmitter 13 may transmit the identification information of the air conditioning unit 1 and the air conditioning temperature stored in the memory 16 to the outside. Furthermore, the transmitting unit 13 may transmit driving state information of the driving unit 17, for example, on / off, temperature, air volume, wind speed, flow rate, and the like of the air conditioning unit to the central control unit. When the air conditioning unit 11 intends to control one or more air conditioning units in the same state, the identification information may be omitted.

The switch 19 is an on / off switch and may control whether or not power is supplied to the driving unit 17.

The driving unit 17 may include an actuator such as a valve, a motor, a fan, and the like.

The driving unit 17 controls the flow rate and the temperature to be adjusted to the desired temperature, that is, the control signal received from the above-mentioned switch 19 on or outside. In addition, the driving unit 17 stops driving in accordance with the stop control signal received from the above-described switch off or outside.

The detector 14 is a sensor that can detect whether there is a person or a person's movement in the room, and may correspond to an infrared sensor, an ultrasonic sensor, a human body sensor, a motion sensor, an image photographing and a recognition device, and the like. have.

The controller 15 controls the driving of the driving unit 17 to adjust the flow rate and temperature in accordance with the desired cooling and heating temperature stored in the memory 16.

In addition, when the air conditioning unit is controlled by a control signal received from the outside, the controller 15 determines whether there is a person in the room or a person's movement according to the detection result of the sensing unit 14 described above. When there is a person or when there is a movement of a person, the air conditioning unit notifies that the signal is received when a signal is received from the outside, or a notification that the air conditioning unit is controlled by a signal received from the outside The information is output through the output unit 18. The notification information may be stored in advance in the memory 16.

In addition, the controller 15 controls the driving of the driving unit 17 according to a control signal received from the outside, that is, a control signal for cooling / heating state, when there is no person in the room or no movement of the person as a result of the sensing unit 14. . The control signal received from the outside may include a minimum heating and cooling temperature to maintain the minimum heating and cooling in the absence of people in the room. Accordingly, when there is no person in the room or there is no movement of the person, the driving unit may be adjusted to the minimum heating and cooling temperature at which less heating and cooling energy is consumed than setting the desired temperature, rather than controlling the driving of the driving unit 17 according to the desired heating and cooling temperature. By controlling the operation of 17) or turning off the air-conditioning unit, unnecessary energy can be saved when no people are in the room.

In addition, the controller 15 may operate the sensor 14 at a time interval previously stored in the memory 16 to check whether there is a person in the room or there is a movement of the person at a predetermined time interval. In addition, the controller 15 may provide a detection result in response to whether there is a person or a person's movement at the request of the central control unit.

The output unit 18 may be a speaker, a light emitting device, a vibration device, and / or a display.

For example, the output unit 18 may output notification information, for example, a notification sound, indicating that the air conditioning unit is controlled according to a control signal received from the outside. Accordingly, the person in the room can hear the notification sound and easily recognize the control state of the air-conditioning unit, thereby quickly changing the control state of the air-conditioning unit. That is, the person in the room can hear a notification sound, for example, by shaking hands to recognize that there is a person or a person in the room, for easy heating and cooling to the desired temperature stored in the memory 16 without any additional operation You can control the unit. In this case, the desired temperature may be a temperature set by a person in the room when the air conditioning unit is operated.

In the above, the driving unit 17 is driven to adjust the heating / cooling temperature in the room to a desired temperature or a minimum temperature based on a result detected by the detector 14 detecting whether there is a person or a motion of the room. In another embodiment, the heating and cooling in the room based on the detection signal received by the receiving unit 12 received from the detection means (not shown) for detecting whether there is a person in the room or the movement of the person The drive may be driven to set the temperature to the desired or minimum temperature.

The on signal of the switch 19 is a signal for driving the driver 17. This on signal may be selected by an administrator or by a person in the room or received by a wireless remote controller.

Next, the controller 15 controls the driving of the driving unit 17 to adjust the flow rate and temperature to match the cooling and heating temperature stored in the memory 16 (S13). The cooling and heating temperature stored in the memory 16 may be a desired temperature (desired cooling temperature or desired heating temperature) selected by a person in the room or received by the wireless remote controller.

Next, the controller 15 determines whether an off request of the switch 19 has been received (S15). The request to switch off 19 may likewise be selected by an administrator or an entrant in the room or received by a wireless remote controller.

When the request for turning off the switch 19 is received as a result of the determination of step S15, the controller 15 stops driving of the driving unit 17 (S16) and stops the operation of the air-conditioning unit.

As a result of the determination in step S15, when the off request of the switch 19 is not received, the controller 15 determines whether a control signal has been received from the outside by the receiver 12 (S17).

When the control signal is not received from the outside as a result of the determination of step S17, the controller 15 moves to the above-described step S13.

When the control signal is received from the outside as a result of the determination in step S17, the controller 15 outputs notification information indicating that the control signal is received from the outside through the output unit 18 (S19).

Next, the controller 15 receives a detection signal that detects whether there is a person or a person's movement in the room by the detector 14 (S20). Although the present embodiment has been described as performing step S20 after step S19 described above, the present invention is not limited thereto and may be implemented to receive a detection signal at any step before step S21 described later.

Next, the controller 15 determines whether there is a person or a person's movement in the room based on the detection signal detected by the detector 14 (S21).

If it is determined in step S21 that there is a person or movement of a person in the room, the controller 15 moves the process to step S13 described above to drive the driving unit 17 to adjust the heating and cooling temperature stored in the memory 16. To control.

If it is determined in step S21 that there are no people or no human motion in the room, the controller 15 controls the actuator 17 according to a control signal received from the outside (S23). In this case, the control signal may include a cooling and heating temperature, a wind speed, a flow rate, and a wind direction designated by an administrator, and may include a minimum temperature when there is no movement or no movement of a person in a room for a predetermined time.

Next, the controller 15 transmits notification information including the driving state of the driving unit 17 driven according to the control signal to the central control unit (S25). At this time, the notification information includes the identification information of the air-conditioning unit when integrated management of the air-conditioning unit installed for each room in the building.

Next, the controller 15 outputs notification information indicating that the air conditioning unit is controlled by the control signal received from the outside through the output unit 18 (S27). Thereafter, the process moves to the above-described step S20 to detect whether there is a person in the room or the movement of the person.

Although the present embodiment has been described as performing step S20 after step S27 described above, the present invention is not limited thereto and may be implemented by moving to any step between step S15 and step S21 described above.
