On the casing (7) an additional humidity sensor (13) provides a measured value from the air supplied.

The arrangement has a temperature sensor (6), a heated vertical or inclined convection shaft (2) behind a front panel (10), a lower opening (3) and an upper opening (4), whereby a closed air guide is guaranteed from the vehicle interior to the convection s...

The controller responds to measures (22,122,222) of pressure (P1) of refrigerant fluid measured between the exit of the expander and the output of the evaporator, and pressure (P2) measured (23) at the compressor input. The controller (401) applies an equa...

An automotive air conditioning system 10 is provided that includes a duct 12 for introducing a flow of air into a vehicle cabin and a closed-loop refrigeration circuit that includes a condenser 30 and an evaporator 16. The improvement comprises a temperatu...

The process makes it possible to determine the air flow rate of a heating, ventilation and air conditioning unit (1) and comprises the following steps: 1) the current consumed by the motor (12) of the fan (10) and the air flow rate is measured in a plurali...

The temperature sensor (30) is located behind a wall (18) surrounding the interior (10). A processor produces a representative output from the sensor signal. A thermally-conductive element (36) is used in sensing the air temperature close to the wall. This...

A blower air flow sensor determines the rate or throughput of the air flowing into the interior space via an outlet opening. A blower air regulator controls a temperature setting device and an air quantity setting device in order to minimize the absolute v...

A climate control system (1) includes a compressor (2) with its output (2b) connected to the intake of a condenser (3) upstream of fluid-expansion means (4) and an evaporator (5) with its output connected to the suction intake (2a) of the compressor (2). A...
