Air conditioner control system
First Claim
1. An air conditioner control system for an automotive vehicle, including a vehicle frame, an electrical power supply, an ignition circuit, an air conditioner compressor, and an electrically-controlled clutch for actuating and de-actuating the air conditioner compressor, comprising:
- (a) compressor switch means connected to said electrical power supply for actuating the air conditioner compressor when said compressor switch means is in an operative position and for de-actuating said compressor when said compressor switch means is in an inoperative position,(b) an electric timer circuit coupled to said electrical power source through said ignition circuit, and to said compressor switch means, said timer circuit functioning to render said compressor switch means inoperative when said ignition circuit is initially turned on and during the timing period of said timer circuit, said compressor switch means being rendered operative at the end of said timing period,(c) an inertial switch mounted on said vehicle frame, normally non-conducting, but being conductive when said vehicle frame attains a predetermined acceleration value and grade,(d) said inertial switch being coupled to said timer circuit, and functioning to render said compressor switch means inoperative while said inertial switch is conducting and during the timing period of said timer circuit after said inertial switch becomes non-conducting.

Abstract
An air conditioning control system for an automotive vehicle including a timer circuit connecting the ignition circuit to a compressor switch means, functioning to turn off the air conditioner compressor for a predetermined timing period after the ignition switch is turned on. The system also includes an inertial switch, such as a mercury switch, which is rendered conductive when the forward acceleration and/or grade of the vehicle attains a predetermined value. The conduction of the inertial switch immediately de-actuates the air conditioner compressor, and the air conditioner compressor remains inoperative as long as the inertial switch is conductive and for the predetermined timing period of the timer circuit after the inertial switch is rendered non-conductive.
