4 is a view showing a configuration of an air conditioning unit of an air conditioner system according to the present invention. As shown in Fig. 4, the air conditioning unit 1 can be classified as follows.

The air conditioning unit 1 includes an air supply unit for supplying air to the room through the duct 3, a ventilation unit for circulating and returning the room, an exhaust unit for discharging the air to the outside, an outside unit for sucking the outside air, And a heat exchanger for exchanging heat between the ventilator and the outside air. At this time, each part is configured to be modularly added or removed. At this time, the exhaust part and the outside air part are constituted by one module to form a mixing part.

The ventilation part is provided with a fan 56 for sucking the returning ventilation. The air supply unit is provided with a fan 58 for supplying outside air or a mixer to the room through a duct. At this time, the fans 56 and 58 provided respectively in the ventilation part and the air supply part are connected to the fan motors 57 and 59, respectively, and rotate according to a control command of the controller 4, and air flows accordingly. The fan motors 57 and 59 provided in the ventilation unit and the air supply unit are inverter motors operated according to the set frequency, and each fan is turned on and off as well as controlling the rotation speed of each fan. The ventilation unit and the outer base unit may each have one to six fans, and each fan may be independently operated. At this time, the fan is modularized as described above to facilitate addition, separation and removal.

The fan motor provided in the ventilation part and the supply part is operated by a drive unit (not shown). The controller 4 applies a control command to the drive unit, and the drive unit rotates the fan by controlling the fan motor in accordance with the control command.

The outer base is provided with a first damper (51) for adjusting the degree of inflow of the outside air. In addition, a second damper (52) for discharging a part or all of the circulation returning air to the outside is provided in the exhaust part. The amount of air discharged to the outside is determined by the amount of opening of the damper. A third damper (53) is provided between the outer base and the exhaust to regulate the supply of some or all of the ventilation to the air supply. The controller (4) adjusts the opening of the first to third dampers (51 to 53).

The third damper 53 and the first and second dampers 51, 52 between the outer base and the exhaust are opened and closed in cooperation with each other. At this time, as the fan provided in the ventilation unit and the air supply unit rotates, air flows and the air flow path is determined according to the degree of opening / closing of the damper, thereby controlling the exhaust and the outside air by the pressure inside the air conditioning unit.

For example, when the third damper 53 is opened at about 67 degrees so that 70% of the ventilation is supplied to the air supply, the second damper 52 of the air supply unit is opened 23 degrees and 30% of the ventilation is discharged to the outside. At this time, the first damper 51 is opened 23 degrees so that the outside air is supplied. When 70% of the ventilation is supplied to the air supply and 30% of the air is exhausted to the outside, 30% of the outside air is supplied by the internal pressure, and the air supply becomes a mixture consisting of 70% ventilation and 30% outside air .

When the third damper 53 is closed, the second damper 52 is opened 90 degrees and the first damper 51 is opened 90 degrees, the ventilation is exhausted to the outside, Air is supplied to the room. Hereinafter, the outside air is supplied as 100% air supply.

The outside air or the mixer is heat-exchanged through the heat exchanger and is supplied to the room through the air supply unit as cold air. The heat exchanger is provided with a heat exchanger (60) and an expansion valve (61). The controller 4 sets the target temperature to the outdoor units 2 (2a to 2c) and controls the expansion valve so that the outdoor air or the mixer has a specific temperature according to the set target temperature. As the refrigerant supplied from the outdoor unit 2 flows into the heat exchanger through the expansion valve, the outdoor air or the mixer passing through the heat exchanger undergoes heat exchange and becomes air at a predetermined temperature. At this time, either of the water-cooled type, air-cooled type, or a combination of both of them can be used as the heat exchanger.

The controller 4 can control the temperature of the supply air supplied from the air supply unit by the room temperature according to either the air supply mode or the ventilation mode, Can be controlled. That is, in the case of the air supply method, the temperature of the air supply is supplied so as to be the target temperature, and in the case of the ventilation method, the temperature control is performed in accordance with the target temperature based on the air temperature.

At this time, the interface unit 5 inputs data to the controller 4, and based on the data stored in the controller 4, outputs the operating state and the air flow of the air conditioning unit 1 to the monitoring screen. The interface unit 5 outputs the setting menu for the air-conditioning unit, and transmits the data inputted through the setting menu to the controller 4 to set the basic data for controlling the air-conditioning unit.

The controller 4 can perform commissioning by supplying power to each module on a module-by-module basis in response to a control command input through the interface unit 5. [ Further, the air conditioning unit is commissioned by transmitting a test commissioning command for each apparatus to the selected apparatus. At the time of commissioning, the controller 4 transmits a commissioning command to a predetermined device, receives the operation state data of the committee, and transmits the commissioning data to the interfacing unit 5, thereby providing a monitoring screen for commissioning of the air conditioning unit via the interfacing unit 5 .

In addition, the controller 4 compares the input data with the actual operation state of each device to generate a test run report for the test run performed.

The interface unit 5 provides a menu for trial operation of the air conditioning unit and transmits the data inputted through the trial operation menu to the controller 4 and thereafter, in response to the data received from the controller 4, And outputs a monitoring screen to the user. Further, a test run report generated from the controller 4 is output to the screen.

Among the additional functions, the air conditioning humidifier and the humidifier can be set when a humidifier is installed in the air conditioning unit 1, and the preheating coil is set when a device for supplying a heat source such as a heater or a boiler to the air conditioning unit 1 is installed. When a function not provided in the air conditioning unit 1 is selected, the controller 4 generates an error, and the interface unit 5 outputs an error to the screen.

The warm-up time 373 can not control the room temperature by performing the set operation immediately after the start of operation when the air conditioning unit 1 is in operation, and it takes time for each device including the outdoor unit to prepare for operation. The time is set. At this time, during the warm-up time, the air conditioning unit 1 starts the operation of each device according to the set operation mode such as controlling the damper and controlling the heat source, and starts the set operation when the operation is enabled. At this time, even if the condition for starting the operation is not satisfied, the controller 4 controls the air conditioning unit 1 to operate according to the operation setting when the warm-up time elapses. That is, the warm-up time is a maximum allowable time for warm-up, and is intended to prevent the delay of the operation so that the warm-up operation is not maintained for a long time.

The ventilation mode (374) enables the ventilation mode setting (375) depending on whether or not the annual ground level sensor is installed. In some cases, ventilation mode setting is possible when a fire signal is input from the smoke detector of the building controller. In the ventilation mode 374, a damper setting 376 and a fan operation setting 377 are possible.

In the damper setting 376, the opening angle of the outside air damper, the exhaust damper, and the mixing damper can be set, and the frequency for the rotation operation of the ventilation fan and the air supply fan can be set in the fan operation setting 377.

The controller 4 can set the opening degree of the damper of the air conditioning unit 1 in accordance with the damper setting 376 when the ventilation mode is set, smoke is detected by the annual earth sensor, or a fire signal is received. In the event of a fire, the outdoor unit stops its operation and the series of operations including the air conditioning unit 1 and heat exchange are stopped, but the damper operates at the designated opening degree according to the ventilation mode setting. In addition, the controller 4 causes the ventilation fan and the air supply fan to operate at a predetermined frequency according to the fan operation setting 377. [

15, when the second system setting tab 362 is selected from the system setting menu 313 of the interface unit, a menu screen composed of the sensor range 378 and the heat source-ensuring temperature range 379 is displayed do.

The sensor range 378 sets a range of values that can be sensed for a plurality of sensors installed in the air conditioning unit 1 in accordance with the characteristics of each installed sensor. It is possible to input the sensible minimum value and the maximum value of the sensor, respectively, so that various models can be selectively installed in the air conditioning unit 1 without installing the sensor of the specified specific model.

If the sensor range is not input for the installed sensor and the corresponding sensor is set to be installed, the initial value is automatically inputted, and if the sensor related function is selected, the initial value is determined as the sensor data.

When the sensor range is set, the control unit 111 stores the data in the data unit 116 and transmits the setting data to the main unit 110 of the controller 4. [

The heat source ensuring temperature range 379 sets the minimum value and the maximum value of the temperature that can be ensured for the cooling heat source and the heating heat source when the temperature of the air conditioning unit 1 is controlled. The minimum value and the maximum value of the heat source-ensuring temperature serve as a criterion for judging whether the outdoor unit is further operated or the driving number is reduced in controlling the number of outdoor units. For example, if the temperature of the supply air temperature exceeds the maximum value of the supply air temperature during the cooling operation, the outdoor unit is further operated. If the temperature is lower than the minimum value, the number of the outdoor units in operation is decreased. Also, even when the number of outdoor units is not controlled according to the heat source ensuring temperature, the indoor temperature is controlled so as not to deviate from the maximum value and the minimum value of the heat source ensuring temperature. That is, the heat source ensuring temperature range 379 is a controllable temperature range in temperature control.
