| 摘要 |
The invention is a device to maintain a continuous volume and pressure in a Freon ( TM ) operated air conditioning unit. Outside ambient temperature is used as a baseline for the on/off switch. Vital components include a 110 volt to 24 volt transformer, a pair of electromechanical operated solenoid valve, a pressure and volume gauge, a compressor, and a timer. All devices are connected to a Freon tank-operated air conditioning unit and can be instituted into either enclosed structure or automotive air conditioning systems.
