Embodiment Construction

[0049] according to figure 1 , An air conditioner installed in a car, for example, includes an inner heat exchanger 1 constituting an evaporator, and an internal air flow 2 passes through the inner heat exchanger 1 . The heat given by the inside air to the refrigerant contained in the inside heat exchanger 1 will heat and evaporate the refrigerant while the inside air is cooled. The heated or vaporized refrigerant reaches the compressor 3 which compresses the refrigerant. The pressure at the output end of the compressor can be measured by the pressure sensor 4 . The compressed refrigerant reaches the outer heat exchanger 5 where it releases part of the heat it contains or condenses. The external heat exchanger 5 can also be described as a liquefier or a condenser, since a gaseous refrigerant can condense therein by releasing heat. During the subsequent course of the refrigerant cycle 6 , the refrigerant flows through an expansion or decompression device 7 , such as a thrott...

Abstract

The method involves determining a load parameter e.g. pressure produced by compressor (3), of an air conditioning apparatus and velocity of a motor vehicle relative to ground and / or air. An outside temperature is determined. An optimal setting e.g. air conditioning apparatus power consumption setting, of a radiator venetian blind (14) is determined for controlling cooling air flow (13) using the determined load parameter, the velocity and the temperature. The venetian blind is actuated in accordance with the determined optimized setting. An independent claim is also included for a device for controlling cooling air flow of an external heat exchanger of an air conditioning apparatus of a motor vehicle.

Description

technical field [0001] The present invention relates to a method and apparatus for regulating motor vehicle cooling air flow. Background technique [0002] One or more heat exchangers are usually placed at the front of the car to discharge the heat generated by the operation of the engine and other powertrains to the outside world. For this purpose, the air flow generated by the dynamic pressure and possibly the radiator fan, which the vehicle develops during travel, flows through the heat exchanger(s) and the engine compartment. In an air-conditioned car, an external heat exchanger of the air conditioner is usually installed in the radiator part of the engine to discharge the heat in the cab to the outside world. Here, the airflow through the outer heat exchanger is also generated by dynamic pressure and / or one or more fans. [0003] In particular, the use of dynamic pressure to create a cooling air flow at high speeds has the consequence of increasing the air resistance ...
