An electronic refrigerant charging-pressure display system includes a charge pressure display part provided on a printed circuit board installed around a high-pressure gauge, the charge pressure display part being designed to display a shortage/excessiveness indication range, a charge identification state range, and a proper charge range of refrigerant being charged into an air conditioning system; an ambient condition setting part for setting the shortage/excessiveness indication range, the charge identification state range, and the proper charge range in response to ambient conditions; and a control part formed of an electronic circuit that is controlled such that the shortage/excessiveness indication range, the charge identification state range, and the proper charge range of the charge pressure display part can be displayed in response to the ambient conditions set by the ambient conditions setting part. |
