摘要： PROBLEM TO BE SOLVED: To ensure a comfortable indoor environment in a short time and to sustain the comfortable state by controlling the air conditioning capacity of an indoor air conditioner and a floor heating air conditioner individually while interlocking. SOLUTION: The inventive system utilizes hot air subjected to heat exchange through refrigeration cycle. A hot air floor heater comprises a room temperature sensor Ta at the air inlet thereof, a heat exchanger temperature sensor Tc, a floor face temperature sensor Tf, and a floor duct temperature sensor Tduct connected respectively with the operation control section. The control section comprises a computer and performs operation control of an air conditioning system based on preset target room temperature, target floor face temperature, and detection temperatures from respective sensors. More specifically, floor face temperature difference is controlled within 3 deg.C and the floor face temperature is controlled higher than the room temperature by 2 deg.C or more.

摘要： PROBLEM TO BE SOLVED: To keep condensed water from being frozen even under a high frequency operation of a compressor by restricting spraying condition with a rise in moisture within a room to be air conditioned after the restarting of the compressor during the cooling operation. SOLUTION: A room fan 102a and a damper unit 2 are controlled so that air blown from a room unit 102 is blown outside a room 101 to be air conditioned for a fixed time length via an exhaust duct 1 when a compressor is stopped because of the turning OFF of a thermostat or the stoppage of operation and condensed water of a room heat exchanger 102b is discharged outside the chamber to be air conditioned. This enables the removal of the condensed water of the room heat exchanger after the restarting of the operation of the compressor to keep moisture attributed to re-evaporation from being released into the room to be air conditioned thereby eliminating a rise in the moisture within the room.

摘要： PROBLEM TO BE SOLVED: To more quickly perform the removing of moisture condensation by jetting air from a near-by blow out port by opening a first damper, when moisture condensation is generated on the surface of a radiation duct. SOLUTION: When moisture condensation generates, a first damper is opened, and an air passage is changed. Then, air (hot air) which is heated warmer than the temperature of suction air is jetted to the surface of a radiation panel 104 on which the moisture condensation has generated by a low air volume, and water drops are evaporated. After the moisture condensation has been totally removed, the blowing out direction from a direct blow out port 1 is changed to an indoor air 105 side by an air volume control of an indoor unit 101, and the air is controlled so that it may circulate in a room. Then, a low temperature dehumidifying control for cooling dehumidification is performed by the indoor unit 101. When an indoor humidity becomes 65% or less, the moisture condensation removing operation is completed, the first damper 2 is closed, and a radiation cooling operation is started. Thus, moisture condensation is evaporated by heating the radiation panel surface 104 with hot air, and the moisture condensation removing operation is completed in a short period of time.
