Abstract

Process for and arrangement for a process to enable a cooling cycle to switch to two or several pairwise different temperature ranges for the evaporator-condenser, also with different temperature spans in between, whereby a programme controller (P) transmits signals initiating the change-over function in such a way that more or less cooling medium is taken from or passed to a coolant container (R2) connected in parallel with the condenser (K) in response to impulses from external transducers signalling that a lower or higher amount of energy should be given off by the cycle, and that when drying materials most energy is given off when the material is coldest and wettest at the start of the drying process and that instead the temperature is highest at the end, and that when utilising the system for heating it is now possible to select different suitable temprature ranges by means of the change-over function, which are adapted to the possible energy absorption and dissipation, respectively, and that defrosting can now be effected during continuous operation and utilisation for air conditioning becomes possible as also the cleaning of flue gases through moistening and electrical charging and following liquid condensation separation on the evaporator (F1, F2).
