J. BerghmansManchmal denke ich, wenn es möglich wäre, eine Geschichte oft genug zu erzählen, damit die Verletzung sich legt und damit die Wörter die Arme herunter und von mir abgleiten, würde ich diese Geschichte tausendmal erzählen.

Vapour Compression Heat Pump Fluids Properties and Selection,The fluid of a heat pump plays an essential role as heat is moved through the pump by its flow: the vaporization of the fluid collects the low temperature heat from the outside source, its condensation releases the heat at a higher temperature level. This operation implies, as shown in Figure 1, that the fluid is compressed before being condensed.

Developments in Vapour Compression Heat Pumps,Until recently the vast majority of vapour compression heat pumps and refrigerators worked on the Rankine Cycle and were powered by an electric motor drive. However research and development work is proceeding to enable advances to be made with this system and to investigate and exploit the potential of alternative cycles and power sources.

Absorption Heat Transformer Cycles,The extensive efforts in the field of energy conservation during recent years also require an intensified research and development activities in the heat transformer sector. This field has been neglected hitherto, though the principles were laid down first by Altenkirch in 1918 and later in a more comprehensive form by Nesselmann in 1933.

Heat Pump Absorbers,The rate of absorption of a pure gas or vapour in a liquid is governed by the rate of diffusion of the absorbed gas within the liquid.
