Abstract (en)
[origin: EP0801278A2] The device uses a zeotropic refrigeration medium and includes a suction gas/liquid gas internal heat exchanger (5) for increasing the vapour pressure. A sensor (6) for the expansion valve (4) between the heat extraction and heat delivery heat exchangers is positioned on the low pressure side of the internal heat exchanger. In the case of a number of internal heat exchangers, the sensor for the expansion valve is positioned between the last internal heat exchanger and the compressor.
