Title: Air conditioner
Inventor: TANAAMI HIROSHI
IPC: F24F11/02
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To prevent odor from being generated even just after an air conditioning operation is carried out by a method wherein an operation of a main air blowing means is stopped while a predetermined time is counted and a ventilation port at a downstream side is opened and the air blowing means at the downstream side is operated. SOLUTION: As a cooling operation is started, a micro-computer turns on a clutch of a compressor in such a way that the compressor for compressing refrigerant is rotated in cooperation with an operation of an engine and then a blower fan motor 8 stops operation for 10 seconds from the starting operation of it. In order to compensate a decrease in cooling speed within a vehicle compartment, a forced ventilation port 20 is opened for 10 seconds from its operation and a forced ventilation fan actuator 13 continues to rotate during this period. With such an arrangement as above, it is possible to prevent air from being applied to the surface of an evaporator before water is adhered to the surface of the evaporator, resulting in that odor constituents are prevented from being blown out of the air conditioner together with air and generating bad odor.
