A heat delivery system for agricultural applications, the system including: piping including alternate heat insulated segments and heat transferring segments, the piping being configured with a fluid flow path extending through the alternating heat insulated segments and heat transferring segments; and a fluid propelling arrangement configured for motivating flow of heat accommodating fluid within the fluid flow path.

A multi-source ground-to-air heat transfer system is configured to store thermal energy during a cooling/dehumidification mode of operation for future use during a heating mode of operation. The multi-source ground-to-air heat transfer system utilizes a ground loop that is configured under an enclosure, such as a greenhouse, and is in thermal communication with a thermal reservoir medium to conduct and store heat. A thermal exchange fluid is pumped through the ground loop and ground heat exchanger and may receive heat from a condenser during a cooling/dehumidification mode of operation and may liberate heat to the evaporator during a heating mode. The enclosure air may receive heat from the heat pump during a heating mode and may liberate heat to the evaporator during a cooling/dehumidification mode. The heat exchange system may employ a heat pump having a reversing valve to change the mode of operation.

There is disclosed a combined net house and indoor farming system comprising a net covering the net house while allowing sunlight to pass through; and a plurality of photovoltaic (PV); wherein the plurality of PV panels simultaneously shades the net house and supplies energy to the indoor farming system. The plurality of PV panels cover a maximum of 50% of the net house.

An aquaponic greenhouse is described comprising at least one hydroponic planter, at least one aquatic tank configured to support aquatic life, an irrigation system linking the at least one hydroponic planter and said at least one aquatic tank; a biofilter configured to process waste from the aquatic life to be used to provide nutrients to plants in the at least one hydroponic planter, a geothermal heat exchange system; and a hydronic radiant flooring system.

The invention provides a compact and self-sustained refrigeration system for agricultural uses, including in Vertical Farming. Greenhouses. LDS. Orchards. and home gardening uses, including in field extreme situations, in post-Harvest uses and in Aquaculture including Algae Farming, independent of external power supply, fueled by small amounts of liquid carbon dioxide.

A heat exchanger for temperature control of a substrate for cultivating horticultural products. The heat exchanger has a structure comprising a heat exchange surface arranged for heating or cooling the substrate. The structure is arranged for supporting the substrate for thereby forming a carrier plate with a carrier surface such that the heat exchange surface forms the carrier surface. The heat exchanger comprises or is configured for cooperating with one or more mounts arranged for suspending the heat exchanger to a rack. The structure of the heat exchanger is constructed such as to be self-supporting for supporting the substrate at least between the one or more mounts, such that a bottom surface of the structure opposite the heat exchange surface faces an ambient environment.

The invention concerns a system and method for energy and hydrometric control of a horticultural greenhouse. The present invention proposes a perfect and complementary arrangement of various energy sources while optimizing them. The use of fossil energy is significantly reduced, making it possible to achieve carbon neutrality, whatever the season and/or climate, and external CO.sub.2 becomes a usable and manageable source of fertilizer. In particular, the invention optimizes the use of heat pumps and other energy sources, preferably alternative energy sources such as hydraulic, wind, solar, geothermal, biofuel or a mixture of these.

A system for collecting waste heat from computing components and delivering the collected heat for useful applications is provided. At least a first heat exchanger is provided to collect the waste heat generated by the computing components. A further heat exchanger is provided to transfer the heat collected by the first heat exchanger and deliver it for useful applications. The useful applications can include providing heat to a building (e.g., residential, commercial, agricultural building). A controller is provided to operation of the components of the heat exchangers (e.g., fans, pumps, valves) to ensure that the computing components are maintained at a suitable temperature.

A greenhouse, for cold weather climates, is configured with a gable that is offset toward the north wall and therefore the south extension of the roof, from the gable to the south wall is longer than the north extension. A greater amount of light can enter through this south extension and the inside surface of the north wall is configured with a reflective surface to allow light to be more uniformly distributed around the plants. The north wall may have no widows and may be thermally insulated to prevent the greenhouse from getting too cold during the night. A ground to air heat transfer (GAHT) system may be configured to produce a flow of greenhouse air under the greenhouse for heat transfer, to moderate the temperature of the greenhouse. A thermal medium may flow to a thermal reservoir for heat exchange with the conduits of the GAHT system.
