Method and system for utilizing heat in a plant or animal growing device, and greenhouse

摘要

A method for utilizing heat in a plant or animal growing device includes circulating a heat transfer fluid through a circuit forming a closed fluid loop, heating the heat transfer fluid by a heat source, supplying heat from the heat transfer fluid to a first heat user which may be a thermal desalination unit, and returning at least part of the heat transfer fluid that has been cooled down. The heat transfer fluid supplies heat to at least one additional heat user serially arranged before or after the thermal desalination unit. The temperature ranges of the heat transfer fluid are within the optimal operating temperature ranges of the respective heat users in the fluid circuit. A corresponding system and greenhouse by which the method of the invention may be implemented is also described.

1. A method for utilizing heat in a plant or animal growing device, comprising:
circulating a heat transfer fluid through a circuit forming a closed fluid loop; heating, via a heat source, the heat transfer fluid in the fluid circuit; supplying heat from the heat transfer fluid to a first heat unit including a thermal desalination unit in the fluid circuit, the first heat unit cooling down at least part of the heat transfer fluid; and returning the cooled down part of the heat transfer fluid to the heat source in the fluid circuit, wherein the heat transfer fluid supplies heat to at least one additional heat unit, the at least one additional heat unit connected between and in serial arrangement with the first heat unit before or after the first heat unit.
