Abstract
An intermediate circuit is connected between the compression space acting as a first heat exchanger of the cylinder of a heat pump or a working machine and the water for industrial use or the burning space of an oil burner, the intermediate circulator comprising a second heat exchanger protruding within the water for industrial use. Through the utilization of an intermediate circulator with a gaseous or liquid auxiliary medium is possible to adapt the transfer of heat between the cylinder of the machine and the heat medium to the respective conditions which permits to increase the total efficiency.
