Apparatus for controlling conditions in a plant cultivation facility

An apparatus for controlling conditions in an indoor plant cultivation facility, said apparatus comprising:

• a lighting system comprising:
• an array of two or more electrical lighting fixtures;
• and
• one or more electrical components providing a lighting function, wherein the one or more electrical components are included in each of said electrical lighting fixtures;
• a cooling conduit profile on which said electrical lighting fixtures are attached;
• a cooling rib system arranged on the cooling conduit profile for cooling the electrical lighting fixtures;
• a hydronic cooling arrangement for lowering or impeding the rise of temperature in the indoor plant cultivation facility, said hydronic cooling arrangement comprising:
• a first pump;
• and
• a cooling manifold providing a first circulation loop, and configured to be installed in the indoor plant cultivation facility wherein the cooling manifold is configured to cool the indoor plant cultivation facility with cooling water circulated in the first circulation loop by the first pump;
• and
• a heat recovery arrangement for utilizing excess heat in the indoor plant cultivation facility, said heat recovery arrangement comprising:
• one or more condenser dryers/coolers for collecting water and/or heat absorbed in an indoor air of the indoor plant cultivation facility;
• a second circulation loop connecting the one or more condenser dryers/coolers to a heat storing system for circulating circulation water;
• a heat storing system for storing the excess heat reclaimed by the heat recovery arrangement, which is accumulated in the cooling water circulated in the first circulation loop of the hydronic cooling arrangement and/or the circulation water circulated in the second circulation loop;
• a secondary circuit for circulating circulation water, which is independent with respect to the first circulation loop and/or the second circulation loop;
• and
• a heat pump assembly coupled to the heat storing system and the secondary circuit for transferring the heat from the heat storing system into the secondary circuit.
