- Other characteristic features of the invention are presented in the dependent claims. The advantage of the arrangement according to the invention is the fact that heat energy can be transmitted long distances in pipe systems which are constructed of plastic in the same way as district heating, heat losses during transfer are minor due to a low temperature and that also the energy of the heat pump to be utilized can be fully utilized at the user end. Due to the low temperature of the transferred energy it is possible to use this energy in the summer time also to cool down buildings because the temperature of the transferred energy can be arranged to the needed temperature level, approximately to a value +10° C. with the help of one part of the arrangement or also in such a way that a hot intermediate agent that comes from the compressor in the cooling system is condensed to the temperature of this transferred liquid the temperature of which is lower than for example the outside temperature during hot weather. If sea water is the heat source, the temperature difference between the sea surface and bottom can be utilized by placing vapour/liquid circulation process to function by means of the temperature difference so, that a rotation motion producing power craft can be get in connection with the process either to produce electricity by means of a generator or to give rotation motion for example to a compressor in a heat pump.
