1. An air conditioner, comprising:

  • a setting apparatus that sets an operation mode which a user requests to the air conditioner or an operation condition of the air conditioner for the operation mode;

    a control apparatus with a built-in microcomputer having an inputting unit that inputs information from the setting apparatus, a memory unit that stores various control setting values and programs, a CPU that performs a calculation process and a determination process, and an outputting unit that outputs a calculated result and a determined result from the CPU; and

    a displaying unit that displays the outputs from the outputting unit;

    wherein the control apparatus comprises;

    a recent integrated electricity storing unit that integrates and stores an electricity consumed by the air conditioner, as an integrated electricity, for each operation mode;

    a recent accumulated operation time storing unit that integrates and stores an operation time of the air conditioner, as an accumulated operation time, for each operation mode;

    an actual usage electricity efficiency calculating unit that calculates an electricity efficiency, which is an integrated electricity per unit time for the actual usage, based on a stored value of the recent integrated electricity storing unit and a stored value of the recent accumulated operation time storing unit;

    a recent average setting storing unit that stores a set parameter set with the setting apparatus by the user, as a time weighted averaged data, for each operation mode;

    a setting comparing unit that compares a stored content of the recent average setting storing unit with a set parameter set by the user this time at a start of operation;

    a predicted electricity efficiency speculating unit that speculates the electricity efficiency predicted as a result of the set parameter set this time by the user, based on a calculated result of the actual electricity efficiency calculating unit and a compared result of the setting comparing unit; and

    at least one of an electricity unit price storing unit that stores an electricity unit price on the memory unit or a CO2 emission coefficient storing unit that stores a CO2 emission coefficient;

    at least one of a predicted electricity charge efficiency calculating unit that calculates an electricity charge efficiency, which is an electricity charge per unit time, based on a speculated result of the predicted electricity efficiency speculating unit, and a stored value of the electricity unit price storing unit, or a predicted amount of CO2 emission efficiency calculating unit that calculates an amount of CO2 emission efficiency, which is an amount of CO2 emission per unit time, based on the speculated result of the predicted electricity efficiency speculating unit and the stored value of the CO2 emission coefficient storing unit; and

    wherein any one of predicted information including the electricity charge efficiency calculated by the predicted electricity charge efficiency calculating unit, or the amount of CO2 emission efficiency calculated by the predicted amount of CO2 emission efficiency calculating unit, or the electricity efficiency speculated by the predicted electricity efficiency speculating unit, is displayed on the displaying apparatus, at the start of the operation of the air conditioner.
