Complaint rate calculation means for calculating complaint rates in consideration of thermal feeling entered from vote value input means, a data storage unit for storing complaint rates together with indoor thermal conditions, updating means for calculating a function representing the relationship between thermal conditions and complaint rates in accordance with stored data, and predicted thermal condition calculation means for calculating thermal setting values by substituting entered control information into the function representing the relationship between thermal conditions and complaint rates, can convert a complaint vote of each inhabitant to a characteristic thermal feeling of a group so as to directly reflect the feeling on air-conditioning control.

Air-conditioning control unit

A temperature control device of a heating apparatus comprising: an input unit for receiving input of a set temperature; a heating/cooling unit for raising/dropping temperature of a medium, from which a person receives heat; a set temperature reaching unit for controlling the heating/cooling unit so that temperature of the medium is raised to the set temperature and maintained afterwards; a time judgement unit for judging whether a given time has passed after the temperature of the medium is raised to the set temperature; and an imperceptible temperature change unit for controlling the heating/cooling unit, if the time judgement unit judges that the given time has passed, so that the temperature of the medium drops/rises by an amount within a given range by which human beings cannot perceive changes in temperature at a temperature change rate by which human beings cannot perceive changes in temperature. According to the temperature control device, after a person sets a room temperature, it drops/rises by an amount which cannot be perceived by the person during heating/cooling.

Temperature control device of a heating or cooling apparatus for saving

An air conditioner includes a comprising temperature regulator for regulating air temperature in a room, a circulating mechanism for circulating the temperature regulated air, a first room temperature detector for detecting room temperature in a set location in the room, a second room temperature detector for detecting room temperature in a location lower than the first room temperature detector, and a controllor for controlling the temperature regulator in accordance with outputs from the first and second room temperature detectors so as to efficiently equalize indoor temperatures and reduce energy consumption.

Air conditioner

An air conditioning apparatus including an indoor device having a first heat exchanger, a second heat exchanger, and a radiant panel. Air circulation mode is switched to radiant mode when a room temperature has reached a temperature set by a user. Refrigerant is changeably circulated through the first and second heat exchangers in a cooling operation so that dew is not formed on the radiant panel.
