The present invention discloses an air conditioning (AC) system with compensation and controlling method thereof. The AC system with compensation comprises an environment-adjusting unit, a temperature-detecting unit, a humidity-detecting unit, a non-delayed humidity-estimate unit and a control unit. The non-delayed humidity-estimate unit is used to derive multiple non-delayed humidity-estimate values by calculating or searching from a humidity table. The control unit is used to adjust the power of the environment-adjusting unit based on the multiple non-delayed humidity-estimate values, in order to shorten the time achieving a target-moisture value.

A smoke control system of a building including a supply air duct installed in an interior of the building having a plurality of floors in a vertical direction, including a plurality of openings corresponding to the plurality of floors, respectively, and one end of which is exposed to an outside of the building, a blower that supplies air to the supply air duct, and a plurality of automatic differential pressure dampers installed in a plurality of ancillary rooms provided on the plurality of floors, respectively, to be adjacent to the plurality of openings. Opening areas of the plurality of openings increase as locations of the plurality of openings become farther away from a point, at which air is supplied to the supply air duct by the blower.

Controlling heating and cooling in a conditioned space utilizes a fluid circulating in a thermally conductive structure in fluid connection with a hydronic-to-air heat exchanger and a ground heat exchanger. Air is moved past the hydronic-to-air heat exchanger, the air having fresh air supply and stale air exhaust. Sensors located throughout the conditioned space send data to a controller. User input to the controller sets the desired set point temperature and humidity. Based upon the set point temperature and humidity and sensor data, the controller sends signals to various devices to manipulate the flow of the fluid and the air in order to achieve the desired set point temperature and humidity in the conditioned space. The temperature of the fluid is kept less than the dew point at the hydronic-to-air heat exchanger and the temperature of the fluid is kept greater than the dew point at the thermally conductive structure.
