arrangement for heating the greenhouse and for cooling a cold with a heat pump

摘要

The arrangement is intended for utilising waste heat produced by the cooling unit of a refrigerated store. This heat is introduced either directly or via an air circulation system into a greenhouse, whilst heat from outside can be channelled to the cooling unit as required as in 2722156. As an alternative for heat feed from the outside via the heat conducting external walls of the cold store, the cooling unit can be connected to take up heat from an underground pipe system and/or from a solar collector on the roof of the store.
