An air conditioning device includes a duct module and a heat exchange module. The duct module includes a temperature control unit disposed at a second region of the duct module, a first air flow guide unit disposed between a first region and the second region of the duct module, and a first liquid energy conducting element disposed at the first region of the duct module. The heat exchange module has a delivery duct, an accommodating case, a driver unit, a second air flow guide unit, a heat exchanger and a second liquid energy conducting element. The driver unit drives condensed water to pass through the delivery duct. The second air flow guide unit provides an air flow to the heat exchanger for exhausting waste heat. The second liquid energy conducting element performs heat exchange to cool down.

The technology disclosed is a two stage Indirect/Direct Evaporative Cooling (IDEC) cycle whose novel closed loop topology compels system convergence to a stable operating state, wherein air cooling takes place mostly in the indirect stage. The direct stage then serves principally as a water chiller for that process.

A hybrid air conditioning apparatus includes a first air conditioning device and a second air conditioning device. The first air conditioning device is a cooling and heating air conditioner, and the second air conditioning device communicates with the first air conditioning device. Air modulated by the second air conditioning device is sent to the first air conditioning device for cooling and heating air adjustment. Accordingly, the air discharged from the first air conditioning device has enhanced quality and all kinds of properties in the air are provided uniformly.

The present invention relates to an air conditioner that adjusts room temperature to a set temperature, and the problem to be solved thereby is to reduce the frequency of occurrence of situations in which the room temperature does not approach the set temperature. In the air conditioner, a target suction pressure is set to a value obtained by subtracting, from an evaporation pressure of an indoor heat exchanger, a pressure loss estimation value from an inlet of the indoor heat exchanger to a suction port of a compressor so that an evaporation temperature of the indoor heat exchanger is maintained constant. The displacement of the compressor is controlled so that the suction pressure becomes equal to the target suction pressure. A deviation determination unit determines whether the room temperature is stabilized at a temperature deviated from the set temperature. When the deviation determination unit determines that the room temperature is deviated from the set temperature, a controller changes the pressure loss estimation value so that the room temperature approaches the set temperature.
