PCT No. PCT/EP97/06357 Sec. 371 Date May 19, 1999 Sec. 102(e) Date May 19, 1999 PCT Filed Nov. 14, 1997 PCT Pub. No. WO98/22763 PCT Pub. Date May 28, 1998In a process for regulating a refrigeration system (1) using an expansion valve (4), one side of the regulating member is pressed by the pressure of refrigerant at the evaporator side and the other side of the regulating member is pressed by the vapor pressure of a sensor system (22) whose sensor temperature is determined by the refrigerant saturation temperature and by the heat supplied by a heating element (27). heat supply is regulated depending on a measurement value (overheating or liquid level). Also disclosed is a refrigeration system (1) regulated in this manner and an expansion valve (4) as essential component of such a system. An improved, exonomic and universally applicable regulation can thus be obtained. |
