Title:
DEVICE FOR CONTROLLING THE REFRIGERANT CHARGE OF AN AIR-CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO2004076943
Kind Code:
A3
Abstract:
The device has a portable case (4) in which a memory is inserted. A preset pressure and temperature values are stored in the memory for analyzing and calculating data. Three temperature sensors (C1, C2, C3) and a pressure sensor (C4) are connected functionally to a microcontroller (6) in an analyzing and calculating unit. A display unit is piloted by the analyzing and calculating unit. An independent claim is also included for a control process for load in refrigerant of an air conditioning system.
