Warm sensation calculation apparatus, warm sensation calculation method, air conditioner, and program

1. A warm sensation calculation apparatus comprising:

a calculator configured to calculate a basic index indicating a warm sensation at a part of a human body; and

a corrector configured to correct the basic index to obtain a new index Xi by utilizing, as a correction element, a heat transfer amount due to a blood flow of a human body heat model (MDL), and

wherein:

the corrector corrects the basic index based on the heat transfer amount so as to reflect heat inflow and heat outflow at a transition;

the corrector further corrects the basic index by utilizing, as the correction element, a whole body heat storage amount and an average body temperature due to heat storage of the human body heat model;

the corrector corrects the basic index based on the whole body heat storage amount and the average body temperature so as to reflect the heat storage of the human body at the transition;

the correction element adds a direct correction component to the basic index to increase a degree of coincidence between the basic index and the warm sensation;

the direct correction component corresponds to a linear function of the correction element;

the corrector calculates the new index Xi indicating the warm sensation for each of parts of the human body following:

Xi=Ai+Bi× (SET*)+ Ci ×(SET*)2+ Di×Obi+Ei×Sb+Fi×Tb,

wherein

each of Ai, Bi, Ci, Di, Ei and Fi is a constant set for each of parts of the human body,

(SET*) is the basic index,

Obi is the heat transfer amount,

Sb is the whole body heat storage amount, and

Tb is the average body temperature; and

wherein the new index is being used to affect the control of the operation of a device.
