  The present invention relates to an air conditioning system, and more particularly, to an air conditioning system for linked operation between one or more air conditioning devices and one or more ventilation devices, and a control method thereof.

  Generally, an air conditioning system is a system for cooling or heating indoor spaces such as a residential space and an office room.

  Recently, as multi-family houses and large high-rise buildings have increased, research and development of air-conditioning systems for managing the air-conditioning environment of these buildings has been rapidly carried out, of which the supply of multi-air-conditioning systems has increased .

  Such a multi-air conditioning system has a structure in which a plurality of indoor units are connected to one outdoor unit, and each indoor unit is installed in each room.

  That is, in the multi-air conditioning system, while sharing an outdoor unit, a plurality of indoor units are operated for cooling or heating as necessary to perform air conditioning in each indoor space.

  On the other hand, the air in an enclosed space has a high carbon dioxide content over time due to repeated human breathing, so in particular in the case of office rooms and vehicles where multiple people gather in a small space, Ventilators are often used to replace air with fresh outdoor air.

  The ventilator includes a ventilation duct that connects the room and the outside, and a blower fan that is installed in a duct of the ventilation duct and forcibly blows indoor air and outdoor air. This ventilator repeats the process of discharging contaminated room air to the outdoor side and sucking fresh outdoor air into the room side.

  However, when the cooling and ventilation operations are performed at the same time in the room, the cooled indoor air is exhausted, and hot outdoor air is sucked in, so that the temperature of the indoor air is relatively higher than the cooling temperature and the cooling efficiency is increased. Decreases.

  Similarly, when heating and ventilation operations are performed at the same time in the room, cold outdoor air is sucked, so that the room temperature becomes lower than the heating temperature and the heating efficiency is lowered.

  On the other hand, when the current outdoor temperature is lower than the first outdoor set temperature T1 and higher than the second outdoor set temperature T2, the indoor temperature of the specific space is lower than the first indoor set temperature C1, and the second indoor set temperature. If it is higher than C2, the ventilation device 210 of the corresponding space is set to “weak wind”, and the indoor unit 110 is set to “middle” (S24 to S28).

  When the current outdoor temperature is lower than the first outdoor set temperature T1 and higher than the second outdoor set temperature T2, if the indoor temperature is lower than the second indoor set temperature C2, the ventilation device 210 in the corresponding space is Set to “intermediate” and the indoor unit 110 is set to “weak wind” (S30).

  When the current outdoor temperature is lower than the second outdoor set temperature T2, the ventilator 210 is set to 'strong wind' to maintain the indoor temperature of the corresponding space, and the indoor unit 110 is stopped (S32).

  In this way, in controlling the linked operation between the ventilator 210 and the indoor unit 110 in the summer, the current outdoor temperature is periodically received from all the outdoor units 130 and the indoor temperature is received from all the indoor units 110, and the outdoor The operating conditions of the ventilation device 210 and the indoor unit 110 are reset according to the temperature and the room temperature.

  In order to execute such control for each space, different unique codes for each space are given to the cooling / heating device 100 and the ventilation system 200 installed in each space. Data transmission / reception with the central control device 300 is performed using the given unique code, and space-based interlocking control for the cooling / heating function and the ventilation function becomes possible.

  On the other hand, a plurality of spaces in which the air conditioning apparatus 100 and the ventilation system 200 are installed can be divided into at least one group, and the linked operation of the indoor unit 110 and the ventilation apparatus 210 can be controlled for each group.

  This is because the air conditioning system 100 and the ventilation system 200 installed in each space are divided into groups according to the space, and different unique codes are given to each group, so that the group-specific interlocking control is performed using the given unique codes. realizable.

  FIG. 4 is a flowchart showing a linked operation control method of the air conditioning system in winter.

  As shown in the figure, the central controller 300 periodically receives the current outdoor temperature from all the outdoor units 130, and periodically receives the indoor temperature from the indoor units 110 installed in each space (S50). .

  At this time, the central control device 300 controls the operation of the indoor unit 110 and the ventilation device 210 for each space based on the outdoor temperature received from the outdoor unit 130 and the indoor temperature level of each space. Output a signal.

The outdoor unit 130 and the control means 230, 250, 250 ′ control the operation of the corresponding indoor unit 110 and the ventilation device 210 according to the operation control signal transmitted from the central controller 300.

  That is, the outdoor temperature level received from the outdoor unit 130 is evaluated (S52). If the current outdoor temperature is lower than the first outdoor set temperature T11, the indoor temperature level of the indoor unit 110 is evaluated (S54). .

  When the current outdoor temperature is lower than the first outdoor set temperature T11 and the indoor temperature of the specific space is lower than the first indoor set temperature H1, the ventilation device 210 is stopped to quickly increase the indoor temperature of the corresponding space. The air volume (warm air) of the indoor unit 110 is set to “strong wind” (S56).
