Regulating mechanism for the refrigerant flow to the evaporator or refrigerating systems or heat pumps and expansion valves arranged in the refrigerant flow

摘要

An expansion valve (8), which is arranged between the condenser (2) and the evaporator (3) in the pump medium circulation system of the heat pump and is continuously controllable, is regulated as a function of set values by means of a computer (10), in particular, while taking into account the evaporator input temperature measured by means of sensing devices (5) and/or the evaporator output temperature measured by means of sensing devices (6). Because of the regulating by means of computers, the control is suitable for different heat pumps and/or conditions of use without structurally altering the expansion valve (8).
