-
FIGS. 2 and 3 illustrate air conditioning systems in accordance with a first preferred embodiment of the present invention. - Referring to
FIG. 2 , the air conditioning system includes at least one room cooling/heating unit 110, aventilating unit 120, an air purifyingunit 130, and a controller for controlling the units. The controller is able to communicate with the room cooling/heating unit, the ventilating unit, and the air purifying unit, such that the units are operated interlocked with one another. - For an interlocked operation of the units, the controller includes temperature sensors (not shown), and a microcomputer (not shown). The temperature sensor measures a room temperature, and the microcomputer produces control data for controlling operation of the units. If the temperature measured at the temperature sensor is outside of a range preset at the microcomputer, the controller puts the room cooling/
heating unit 110 into operation. - Moreover, the controller includes a timer for measuring an operation time period of the room cooling/
heating unit 110. When the operation time period measured at the timer reaches to a time period-preset at the microcomputer, the controller puts theventilating unit 120 into operation. Then, outdoor air is introduced into the room by the ventilatingunit 120. At this time, it is preferable that theair purifying unit 130 is operated at the same time for purifying air introduced into the room. - Since the outdoor air having an outdoor temperature is introduced into the room during the ventilation, the room is in an unstable state in which the room temperature varies. In this instance, it is difficult for the room cooling/heating unit to determine which one of the cooling and heating is to be performed. Therefore, it is preferable that the room cooling/heating unit is not operated during the ventilation.
- That is, it is preferable that, if the operation time period of the room cooling/
heating unit 110 measured at the timer reaches to a time period preset at the microcomputer, the controller puts theventilating unit 120 and theair purifying unit 130 into operation, and operation of the room cooling/heating unit 110 is stopped. According to this, an energy consumption efficiency of the air conditioning system can be improved. - In the meantime, the controller in accordance with the embodiment of the present invention includes a room cooling/
heating controller 111, a ventilatingcontroller 121, and anair purifying controller 131. The room cooling/heating controller 111 is able to communicate with the room cooling/heating unit 110, for controlling the room cooling/heating unit 110. The ventilatingcontroller 121 is able to communicate with theventilating unit 120, for controlling theventilating unit 120, and is able to exchange data with the room cooling/heating controller 111, for making an interlocked operation of the room cooling/heating unit 110, and theventilating unit 120. Also, theair purifying controller 131 is able to communicate with theair purifying unit 130, for controlling the air purifying unit, and is able to exchange data with the ventilatingcontroller 121, for making an interlocked operation of above units. - In the meantime, it is preferable that the room cooling/
heating unit 110 is an indoor unit of an air conditioner. The air conditioner includes an outdoor unit and an indoor unit, for making heat exchange between refrigerant flowing in the units, and air, to cool or heat the air selectively. In order to make selective cooling/heating of a plurality of rooms, it is preferable that the rooms are provided with the indoor units, respectively. - In order to individual control of the plurality of room cooling/heating units provided to the rooms, though a plurality of room cooling/heating units may be provided, the room cooling/heating units may be controlled collectively by one room cooling/heating controller.
- For communication between the room cooling/
heating unit 110 and the room cooling/heating controller 111, data transceiverparts heating unit 110 and the room cooling/heating controller 111 respectively, for data transmission/reception therebetween. The data transceiverpart 402 in the room cooling/heating controller 111 receives data from thedata transceiver part 401 in the room cooling/heating unit 110. - In the meantime, the ventilating
unit 120 ventilates the room, selectively. For this, the ventilatingunit 120 includes a duct making the room and outdoor in communication, and a fan provided inside of the duct. The duct is in communication with the rooms, and provided with fans as many as a number determined taking a total capacity of rooms into account. - The ventilating
controller 121 is able to communicate with theventilating unit 120, for remote control of theventilating unit 120. The ventilatingcontroller 121 and theventilating unit 120 exchange data throughdata transceiver parts - Data exchange between the ventilating
controller 121 and the room cooling/heating controller 111 is made throughdata transceiver parts - In the meantime, the
air purifying unit 130 purifies contaminated room air. Theair purifying unit 130 draws room air, removes odor and dust from the room air, and discharges to the room, again. - The
air purifying controller 131 is connected so as to be able to communicate with theair purifying unit 130, for controlling theair purifying unit 130. That is, theair purifying controller 131 and theair purifying unit 130 are connected such that data is exchanged throughdata transceiver parts - Moreover, the
air purifying controller 131 and the ventilatingcontroller 121 are provided with data transceiverparts controller 121 and theair purifying controller 131 are connected such that communication can be made through thetransceiver parts air purifying unit 130 and theventilating unit 120 are operated interlocked with each other. - In this instance, the ventilating
unit 120 is operated in response to a control data from the ventilatingcontroller 121. In this instance, since the ventilatingcontroller 121 provides a control data to theair purifying controller 131, theair purifying unit 130 can be operated interlocked with operation of the room cooling/heating unit 110 and theventilating unit 120. According to this, theunits - Of course, the
air purifying controller 131 is connected to the room cooling/heating controller 111 so as to be able to transmit/receive data, and theair purifying unit 130 and the room cooling/heating unit 110 can be operated interlocked with each other. - In the meantime, it is preferable that one of the room cooling/
heating unit 111, the ventilatingcontroller 121, and theair purifying controller 131 controls a corresponding unit, remotely. That is, it is preferable that at least any one of the controllers is a remote controller. -
FIG. 3 illustrates a diagram showing the controllers controlled by apparatus connected to the Internet. - Referring to
FIG. 3 , it is preferable that at least one of the room cooling/heating controller 111, the ventilatingcontroller 120, and theair purifying controller 130 is controlled with a computer connected to the Internet. That is, one of the controllers is provided to be able to communicate with the computer connected to the Internet, so that the user can control operation of the air conditioning system with the computer, on an outside of the building far from the building. Moreover, error signals from thecontrollers - A method for controlling an air conditioning system in accordance with a first preferred embodiment of the present invention will be described.
- First, in order to maintain a room temperature at a predetermined level, if the room temperature is outside of a preset range, the room cooling/
heating controller 111 puts the room cooling/heating unit 110 into operation. In this instance, the room cooling/heating controller 111 puts the room cooling/heating unit 110 into operation, or stops operation thereof repeatedly according to the room temperature, to maintain the room temperature at an appropriate temperature. - For this, the room cooling/
heating controller 111 or the room cooling/heating unit 110 is provided with a temperature sensor for measuring the room temperature and a microcomputer at one side thereof. If the temperature measured at the temperature sensor is outside of a range preset at the computer, the microcomputer issues an order for the room cooling/heating unit 110 to start operation. Then, the room cooling/heating unit 110 cools or heats room for a preset time period. - A control data performed through the room cooling/
heating controller 111 is transmitted from thedata transceiver part 405 of the room cooling/heating controller 111 to thedata transceiver part 406 of the ventilatingcontroller 121. - In the meantime, if the room cooling or heating is continued for a long time, the room air may be polluted, or short of oxygen. Opposite to this, if the room air is kept ventilated, the energy consumption efficiency of the air conditioning system becomes poor. Therefore, the air conditioning system has the room ventilated after the room cooling/
heating unit 110 is operated for a preset time period. The room cooling/heating controller 111 or the room cooling/heating unit 110 is provided with a timer therein for measuring a time period starting from starting of operation of the room cooling/heating unit 110. When a time period measured at the timer reaches to the time period preset at the microcomputer, a control data is provided from the room cooling/heating controller 111 to the ventilatingcontroller 121. - Upon receiving the signal, the ventilating
controller 121 puts theventilating unit 120 into operation. That is, an operation staring point of theventilating unit 120 is dependent on the operation time period of the room cooling/heating unit 110. During theventilating unit 120 is operated, the room temperature is unstable due to introduction of the outdoor air into the room. Therefore, when ventilation of the room is required, it is preferable that operation of the room cooling/heating unit is stopped, and theventilating unit 120 is put into operation. By doing so, the energy consumption efficiency of the air conditioning system can be improved. - When the
ventilating unit 120 comes into operation, outdoor air is introduced into the room. In order to remove dust from the air, theair purifying controller 131 puts theair purifying unit 130 into operation. That is, a control data informing that theventilating unit 120 is started is provided from the ventilatingcontroller 121 to theair purifying controller 131, theair purifying controller 131 puts theair purifying unit 130 into operation. - Therefore, the
air purifying controller 131 puts theair purifying unit 130 into operation at the same time with the operation of theventilating unit 120. Then, theair purifying unit 130 removes dust and odor from the outdoor air introduced into the room. - In the meantime, the
air purifying unit 130 is operated at the same time with theventilating unit 120, not necessarily. That is, if room air is contaminated heavily, only the air purifying unit may be operated. - After the ventilating and air purifying are performed for the preset time period, the units are stopped. Then, a control data informing that the units are stopped is provided to the room cooling/
heating controller 111, and the controller puts the room cooling/heating unit 110 into operation selectively depending on the room temperature. -
FIG. 4 illustrates a diagram of an air conditioning system in accordance with a second preferred embodiment of the present invention. - Referring to
FIG. 4 , in the air conditioning system, units, particularly, the room cooling/heating units 110 are grouped, and the grouped units are controlled by one controller. Therefore, the air conditioning system is provided with a ventilating andair purifying controller 221 having a combined function of the ventilating-controller and the air purifying controller. - In this instance, the room cooling/
heating controller 211 is connected to the plurality of room cooling/heating units 110 so as to be able to communicate. At least one room cooling/heating unit is provided to each of the rooms, all of which are controlled by one room cooling/heating unit. Of course, the room cooling/heating units 110 may be connected to the room cooling/heating controllers so as to be able to communicate respectively, and the room cooling/heating controllers can be controlled by a separate unitized room cooling/heating remote controller. - The room cooling/
heating units 110 and the room cooling/heating controller 211 havedata transceiver parts 411, and 412 respectively for transmission/reception of data therebetween. The data transceiverpart 412 in the room cooling/heating controller 211 receives data from the data transceiver parts 411 of the room cooling/heating units 110, collectively. - The ventilating
unit 130 and theair purifying unit 120 are connected withdata transceiver parts ventilating unit 120 is started, a control data is provided to theair purifying unit 130 connected to theventilating unit 120, and by the control data provided thereto, theair purifying unit 130 is also operated. - The ventilating and
air purifying controller 221 is connected such that it can communicate with one of theventilating unit 120 and theair purifying unit 130. Therefore, the ventilatingunit 120 and theair purifying unit 130 are interlocked. In this instance, it is preferable that the ventilating andair purifying controller 221 is connected to theair purifying unit 130 so as to be able to communicate with each other. This is because there are cases occurred frequently, in which operation of only theair purifying unit 130 is required. - Accordingly, since the control data is provided from the ventilating and
air purifying controller 221 to theair purifying unit 130 directly, a response speed of theair purifying unit 130 with respect to the control data is improved. - In this instance, the ventilating and
air purifying controller 221 and theair purifying unit 130 are provided with separate data transceiverparts - Of course, though not shown, the ventilating and
air purifying controller 221 may be connected both to theventilating unit 120 and theair purifying unit 130 so as to be able to communicate with each other. - Moreover, the ventilating and
air purifying controller 221 and the room cooling/heating unit 211 are provided with separate data transceiverparts - In the meantime, it is preferable that the room cooling/
heating controller 211 or the ventilating andair purifying controller 221 controls the room cooling/heating unit 110, the ventilatingunit 120, and theair purifying unit 130, remotely. Moreover, as shown inFIG. 5 , it is preferable that the at least one of the room cooling/heating controller 211 and the ventilating andair purifying controller 221 is controllable from a distant place through the Internet. The control though the Internet can be embodied according to a method the same with the first embodiment. - A method for controlling an air conditioning system in accordance with a second preferred embodiment of the present invention will be described
- At first, room temperatures of rooms are measured, and the room cooling/heating units in rooms of which room temperatures are outside of a preset temperature range are put into operation by using the room cooling/
heating controller 211. For this, the room cooling/heating controller 211 is provided with a temperature sensor for measuring a room temperature. - In this instance, a control data is provided to the
data transceiver part 418 in the ventilating andair purifying controller 221 through thedata transceiver part 417 in the room cooling/heating controller 211. - According to this, the ventilating and
air purifying controller 221 knows starting and stopping time points of the room cooling/heating unit 110, and calculates or sets starting times of theventilating unit 120, and theair purifying unit 130. - Therefore, if a time comes, when ventilation of the room is required in the middle of operation of the room cooling/
heating unit 110, the room cooling/heating controller 211 stops operation of the room cooling/heating unit 110. Also, the ventilating andair purifying controller 221 puts both theventilating unit 120 and theair purifying unit 130 into operation, to remove dust and odor from the outdoor air introduced into the room. - In this instance, a control data is provided to the
ventilating unit 130 through theair purifying unit 120. Upon completion of ventilation of the room, the ventilating andair purifying controller 221 stops theventilating unit 120 and theair purifying unit 130. At the same time with this, the control data is provided to the room cooling/heating controller 211, to put the room cooling/heating unit again according to the room temperature. - The ventilating
unit 120 and theair purifying unit 130 in accordance with the second preferred embodiment of the present invention are operated after the room cooling/heating unit 110 is operated for a predetermined time period. That is, it is preferable that starting time control of the ventilating unit and the air purifying unit is performed indicated to the first embodiment. -
