(Embodiment 2-1) The present invention relates to an air conditioning system, and in Embodiment 1-1, a second suction fan 151 accommodated in the second suction duct and sending air to the room; And a second discharge fan (152) accommodated in the second discharge duct and discharging air to the outside.
The flow air inside the case must be given flow energy to enable smooth air flow. To this end, the second exhaust port of the second exhaust duct mounts a second exhaust fan, and the second suction pipe port of the second suction duct mounts the second suction fan. That is, the operation of the second discharge fan discharges the indoor air to the outside through the heat exchanger, and the outdoor air is supplied to the room through the heat exchanger by the operation of the second suction fan.
(Embodiment 2-2) The present invention relates to an air conditioning system, and in Embodiment 2-1, a third discharge fan 153 accommodated in the third discharge duct and discharging air to the outside .
For rapid external discharge of indoor air, the air entering the first exhaust duct flows into the third exhaust duct through the first through-hole opened by the first damper, and the third exhaust fan located in the third exhaust duct And quickly discharges the indoor air to the outside by high-speed rotation. The outdoor air that has entered the third suction duct enters the second suction duct through the second through-hole for rapid indoor supply of outdoor air, and the second suction fan located in the second suction duct quickly The outdoor air enters the room. The air that is discharged at a high speed and enters at high speed flows in and out without going through a heat exchanger. This can be done by a third discharge duct, a third suction duct, a first damper, and a second damper.

(Embodiment 3-1) The present invention relates to an air conditioning system, and in Embodiment 1-1, a first filter (160) accommodated in the first suction duct.
The outdoor air entering the room contains a large number of contaminants and contaminants. When these foreign substances and contaminants enter without being filtered, they cause problems of heat exchanger closure and indoor air pollution. Therefore, it is necessary to shut off the entry of foreign matter and pollutants into the inside of the case. To this end, a first filter is mounted in a first suction pipe passage of a first suction duct into which outdoor air enters. The first filter includes a prefilter formed of a mesh network, a second filter formed of a HEPA filter for filtering dust and bacteria, and a third filter formed of a deodorizing filter for removing odors. The filter is inserted into one filter case to be modularized, and the filter case is detachable from the case and can be replaced and repaired.
(Embodiment 3-2) The present invention is an invention relating to an air conditioning system, wherein, in Embodiment 3-1, a second filter (161) accommodated in the second suction duct; A fan coil 162 for adjusting the temperature of the intake air, a humidification nozzle 163 accommodated in the second intake duct 163 for supplying moisture to the intake air, An oxygen supply nozzle 164 for supplying oxygen, and a fire nozzle 165 which is accommodated in the second suction duct and ejects the extinguishing liquid.
The second suction duct supplies outside air to the room through the second suction pipe passageway of the case. The air conditioning system of the present invention includes functions that conform to various environmental conditions of the room.
Mode 1 is used for the normal air circulation process. The indoor air is comfortably circulated through the exhaust air and the inflow air, and in particular, the air purified by the first filter enters the room. It is used in the process of introducing air that absorbs energy by heat exchanger.
Mode 2 is used when the indoor / outdoor temperature difference is abrupt. During the inflow and outflow of air, indoor air enters the room through the heat exchanger to absorb energy. However, it is impossible to absorb enough energy to satisfy all the heating and cooling conditions. Therefore, a separate air conditioner must be additionally driven. Mode 1 of the present invention includes a cooling / heating device inside the air conditioning system. That is, the fan coil is mounted inside the second suction duct, and the air entering the fan coil can be heated or cooled. The heating medium flowing in the fan coil is operated by flowing the heating medium from the external boiler or the freezer. For the operation of mode 1, the indoor and the other end of the heat exchanger are equipped with respective temperature sensors. The controller determines the difference in signal value obtained from each temperature sensor, and drives the boiler or refrigerator to such an extent that it compensates for the value of the temperature. The fan coil may serve as an inflator of the refrigeration cycle to absorb heat. In this case, the fan coil may include a heating element to realize a heating condition.
Mode 3 is used for rapid ventilation conditions. Indoor air is in a radically polluted state, or contains a large amount of dust. At this time, it is required to swiftly exchange indoor air and outdoor air. In addition, since pollutants may damage the heat exchanger, it must be discharged without going through a heat exchanger. In the room, the contamination measuring sensor and the dust measuring sensor are operated in real time. When the abnormal signal is activated in the sensor, the first damper and the second damper are operated to close the heat exchanger. The first exhaust duct and the second exhaust duct communication are changed to a first exhaust duct and a third exhaust duct communication, which are made up of a first damper. Further, the third discharge fan housed in the third discharge duct is driven at a high speed to quickly discharge the room-contaminated air to the outside. In order to reduce indoor pollution quickly, outside air must be injected quickly. To this end, the first suction duct and the second suction duct communication are changed to the third suction duct and the second suction duct communication, and this consists of a second damper. Further, the second suction fan is operated at a high speed to quickly supply the outside air.
Mode 4 is used when extreme air pollution is severe. Recently, the fine roads have been increasing due to yellow dust and the like. Even if the first filter is accommodated in the first suction duct, there is a limit. Accordingly, the external air supply is interrupted, and the air conditioning system is driven only by the internal air. To this end, a third damper inserted in the middle of the first exhaust duct and the second suction duct is operated. The third damper blocks the first exhaust duct and the second duct intermediate duct, and realizes the condition that the indoor air is not discharged but enters the room again. When the fourth mode is used for a long period of time, the room is not comfortable due to an increase in carbon dioxide. To overcome this, the oxygen supply nozzle of the second suction duct is opened to supply oxygen to the room. Therefore, it is possible to satisfy the deficient oxygen amount in the room. In addition, indoor air must be purified to provide clean air. To this end, a second filter is mounted within the second suction duct to purify the re-entrant air.
Mode 5 is a condition used in an indoor fire. It cuts off the supply of external air when a fire occurs, and drives the air conditioning system with only the internal air. To this end, a third damper inserted between the first discharge duct and the second suction duct is operated. The third damper blocks the intermediate duct of the first duct and the second duct and realizes a condition in which the ducts are mutually opened to enter the room again without discharging the room air. The fifth mode is activated by the indoor smoke alarm signal. The external air supply is cut off to cut off the oxygen supply to the fire space, and the fire nozzle installed in the second intake duct is opened for internal fire extinguishing. The fire nozzle is connected to the external fire extinguisher, and the extinguishing fluid supplied from the fire extinguisher is injected quickly into the room to suppress the fire. To replace the fire alarm signal, the second exhaust duct is equipped with a heat and smoke detection sensor, and drives the fifth mode according to the signals of the heat and smoke detection sensors.
