Fan speed regulating system for air conditioning system used in road vehicle has temperature, vehicle speed, humidity and outside air temperature sensors

摘要

The temperature (17), vehicle speed (18), humidity (19) and outside air temperature sensors (20) are connected to a control circuit (10). This circuit has connections to the fan and to a pressure sensor (7) on the high pressure side of the condenser. The fluid circuit includes a collector (5), a reducing valve (3), an evaporator (4), a pump (1) and a drier (6).
