摘要：
The heat-pump cold-water sets to be developed are primarily intended for heating up process water to 70 degree C. Two problems arise from this requirement and the use of screw-type compressors the solutions to which have an essential influence on the refrigerant and oil circulation in the sets. Described are the problems and the solutions applied to oil treatment and oil recirculation from the refrigerant circuit to the compressor. Information on the efficiency is also given.
