Abstract

In a heat storage air conditioning apparatus, a power demand time-sequence data collecting unit collects time-sequence data on demand for power; a power demand curve estimating unit estimates a power demand curve obtained as a result of analysis of the power demand time-sequence data collected by the power demand time-sequence data collecting unit; a thermal energy load demand estimating unit estimates thermal energy load demand from the power demand curve estimated by the power demand curve estimating unit; an operation unit of a thermal-energy source feeds cooling / heating energy; a heat accumulating unit stores the cooling / heating energy supplied from the operation unit therein; a cold / hot air discharging unit discharges the thermal energy stored in the heat accumulating unit; a cooling / heating energy quantity recognizing unit recognizes the quantity of cooling or heating energy dissipated from the cold / hot air discharging unit; and a converting unit converts the quantity of cooling / heating energy into the quantity of electric power, the converted quantity of electric power being supplied to the power demand time-sequence data collecting unit.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to a heat storage air conditioning apparatus that produces and stores some or all of the quantity of thermal energy during the night, the thermal energy being used to air-condition of a living space in the daytime so that the thus-stored thermal energy is supplied to the living space during the daytime, and a heat storage estimating method.[0003] 2. Description of the Related Art[0004] FIG. 35 is a block diagram of a conventional heat storage air conditioner disclosed in, e.g., Mitsubishi Electric Technical Report Vol. 68, No. 5, 1994. FIG. 36 is a graph showing heat dissipation patterns used in this conventional heat storage air conditioner. FIG. 37 is a graph illustrating one example of transitive temperature data obtained during air-conditioning periods. In the drawings, reference numeral 1 designates a heat source; 2, a heat accumulator; 3, operation control unit for controlling the operations of the heat sourc...
