PURPOSE:To improve the interchangeability of a heater unit by providing a connecting duct affording communication between the rear side path and rear side connection port in a main body while providing an opening and closing door in a port affording communication between the front and rear side paths. CONSTITUTION:When a communicating port 57 is fully closed with a separate door 59, air is blown off from an upper jet 39 and an on-foot jet 41 in the front side path 35. Also, air is sent to the rear side connecting port 42 through a connecting duct 44 in the rear side path 43 and air is obtained independently in the front and rear sides. On the other hand, when the communicating port 57 is fully opened, air in the rear side path 43 flows to the front side path 35 and the whole flow of air is blown off from jets 39, 41. When the connecting duct 44 and door 59 are here removed, the whole flow of air flows into the path 35 to be sent to the jets 39, 41 and connecting port 42. Thus, an independent temperature conditioning type heater unit of standard type is obtained. |
