Method of determining path of variable run piston compressor for motor vehicle air conditioner, involves using flow rates and pressures to determine movement indirectly |
摘要 |
The method of determining the path of a variable run piston compressor for a motor vehicle air conditioner (1) using swash plate pistons determines the path indirectly. The data is taken from a differential pressure PD (11) or a speed V (14) of volumetric discharge and a pressure difference between high pressure DP and aspiration pressure with respect to the compressor speed. The differential pressure can be determined from the compressor volumetric flow and the flow pressure drop across a resistance.
