PURPOSE:To enable the blow-off made to be quickly and easily set to a given bi-level condition by shifting a blow-off mode control lever within a controllable range as indicated by the mark for the bi-level blow-off mode on the control panel when another bi-level condition is required. CONSTITUTION:When a blow-off mode selector lever 20 is placed at a position 1 of the indicator, a ventilation blow-off mode is established allowing the conditioned air to be blown off where the conditioned air is set up by a temperature control lever 21 which is used to rotate an air mixing damper. Then, when the lever is moved to a position 2 of the indicator, an ideal heating condition of B/L1, what is called keeping the head cool and the feet warm, is set up. And when the lever is further moved to a position 3 of the indicator for a B/L2 mode, difference in temperature becomes smaller. When the lever is furthermore moved to a position 4 of the indicator for a B/L4 mode, difference in temperature becomes much smaller as shown by a graph of a slender triangle. Thus, this configuration enables the setting to a given bi-level condition to be quickly and easily effected and there is no need for use of two kinds of control levers in their proper ways even when set in a blow-off mode other than the bi-level mode. |
