An emission free system for delivery of cooling as a cooled liquid to a user includes upper and lower containers (B; Kvf) connected to one another by pipes (7, 8) allowing all the time a free flow of a liquid through the pipes. The liquid located uppermost in the upper container is cooled by a heat pump unit (R) having an evaporator/condenser part at its first end (T1) and an accumulator part at its second end (T2). The first end is placed in the upper part of the upper container and the second end is placed to be periodically heated or the be heated during a time period, after which cooling is to be delivered from the system. |
