Air conditioner with an electronic control device

摘要

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 equation linking mass flow of refrigerant to the difference between the two pressure measures (P1 - P2), to adjust fuel injection (42).
