Method for operating a refrigerant circuit, method for operating a motor vehicle driving engine, and refrigerant circuit |
摘要 |
A refrigerant circuit for a motor vehicle air-conditioning system has a refrigerant compressor, a cooler connected downstream of the refrigerant compressor, a restrictor for expanding the refrigerant, and an evaporator for transferring heat to the refrigerant. Pressure in the refrigerant circuit is measured firstly on the high-pressure side and secondly on the low-pressure side. An air-conditioning system can be driven directly or indirectly by the motor vehicle driving engine. The refrigerant in the refrigerant circuit is almost completely liquefied upstream of the restrictor, so that it is easy to determine the refrigerant mass flow. As a result, it becomes possible to determine the compressor torque which is consumed by the refrigerant circuit and to control the motor vehicle driving engine accordingly.
