A multi-source ground-to-air heat transfer system is configured to store thermal energy during a cooling/dehumidifcation 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.

Described herein are methods of producing plant products and plant production facilities equipped to produce the same on a large-scale. The methods and facilities provide for sprouting directly on a solid growing surface with embedded temperature control, which maximizes independent control of each batch of sprouts or plant products. The embedded temperature control system generally comprises one or more heat transfer conduits for flowing a heat transfer fluid therethrough. A seed spreader device may be used to deposit a bed of plant seeds at a substantially uniform height across the growing surfaces. Advantageously, the simplified design is more cost-effective and can be easily understood, used, and repaired by the average farmer or livestock operator.

A spraying and re-heating vapor reactor includes: a heat preservation boiler; a vapor reaction boiler disposed in the heat preservation boiler; a re-heating conduit communicating the vapor reaction boiler with a device outside the heat preservation boiler, a high heat capacity material being accommodated within the heat preservation boiler, and surrounding the vapor reaction boiler and the re-heating conduit; a heater heating the high heat capacity material; a sprayer disposed in the vapor reaction boiler; and a liquid supplying tube communicating with the sprayer through structure walls of the heat preservation boiler and the vapor reaction boiler, and supplying an external liquid to the sprayer. The sprayer atomizes the external liquid into an atomized liquid absorbing thermal energy from the high heat capacity material and becomes a low-temperature vapor entering the re-heating conduit and being re-heated into a high-temperature vapor. A generator apparatus is also provided.

Disclosed is a smart farm system comprising: a Rankine cycle in which a first fluid passes through a pump, an evaporator, a turbine, and a condenser along a first circulation line; a heating unit configured to exchange heat with the evaporator; a valve unit which is provided between the turbine and the condenser, and configured to run the first fluid to the condenser when the temperature of the first fluid at the outlet of the turbine is a first temperature, and to bypass the first fluid to a bypass line when the temperature of the first fluid at the outlet of the turbine is a second temperature higher than the first temperature; and a smart farm configured to exchange heat with the first fluid and the heating unit via the condenser or the bypass line.

A combined heat and power system for greenhouse carbon dioxide enrichment purifies carbon dioxide from exhaust gas of the combined heat and power system generating and supplying power and heat by combusting fuel and supplies the purified carbon dioxide to a greenhouse. The combined heat and power system includes a unified pipe system configured to simultaneously transmit hot water and carbon dioxide through a single pipe by dissolving the purified carbon dioxide in a heat transmission medium, a storage system configured to store the carbon dioxide transmitted to demand destinations along with the hot water, and supply unit configured to supply the carbon dioxide transmitted to and stored in the demand destinations depending on a heat and carbon dioxide load condition of a demand destination.

A device including a work table having an upper plate elevated from a floor, a cultivation bed disposed on the upper plate and including an accommodation hole to accommodate soil or culturing solution therein, and a flow tube disposed in the soil or culturing solution to supply or drain water to and from the accommodation hole, a supply portion to circulate water in the flow tube to lower the temperature of water, a light emitting portion including a pillar adjustable in height and a UV light source emit UV light toward an upper portion of the cultivation bed, and a power generator including a servo motor disposed below the work table, and a bracket configured to adjust a location of the light emitting portion with respect to the side surface of the work table.

A greenhouse comprises a support frame and a spray pipe including pipes and pipe joints, the pipe joint comprises a connecting pipe and two rotary sleeves, the two adjacent pipes are respectively inserted into the connecting pipe, ends of a first pipe are respectively sleeved with a sealing sleeve and a locking sleeve, and each of the ends of the first pipe is further sleeved with a washer. When the rotary sleeve is thread-tightened, the connecting pipe and the locking sleeve are capable of respectively abutting and pressing against two sides of the washer, under abutting and pushing of the rotary sleeve and limiting of the washer, the locking sleeve is capable of grasping the first pipe and forming an axial positioning with the rotary sleeve. An inner edge of an end surface of the connecting pipe has a sealing tapered surface capable of acting on the sealing sleeve.

The present invention relates to a hydroponic facility for cultivating crops without soil by using a culture solution, and more particularly to a hydroponic facility system for helping to save energy and grow crops in a hydroponic facility, which, when crops are grown through hydroponic facilities using a hydroponic method in many farms, can prevent the destruction of a natural environment attributable to the depletion of underground resources (water resources) and can reduce the economic burden of farmers attributable to a large amount of electricity consumed for constant temperature and constant humidity.
