In this communication, a new adsorptive cycle for upgrading the ambient heat is suggested and briefly analyzed. The main feature of this cycle is that regeneration of adsorbent is performed by dropping the vapour pressure over adsorbent at a constant temperature, rather than by adsorbent heating as usual. This pressure drop is ensured by low ambient air temperature and does not need the supply of energy that has commercial value. It is essential that the regeneration is easier at colder ambient. Since the useful heat that gains commercial value is obtained by means of a low ambient temperature, the new approach is called “Heat from Cold” (HeCol). It can be interesting for countries with cold climate, and especially for the Arctic zone.
