In one or more arrangements, a heating system is provided having one or more heating panels positioned in a housing. The housing has a hollow interior with an open lower end. A first panel is positioned in the open lower end of the housing. The first heating panel includes a heating layer. The heating layer includes a conductive microfilm. A first electrical contact is connected to the conductive microfilm. A second electrical contact is connected to the conductive microfilm. In one or more arrangements, the conductive microfilm includes at least one layer of graphene or nanofiber carbon material. Application of a voltage difference between the first electrical contact and the second electrical contact causes current to flow through the conductive microfilm, thereby generating heat. In one or more arrangements, current which flows through the conductive microfilm causes the conductive microfilm to emit infrared radiation.

The first object of the invention is a production line for rearing and/or breeding insects and/or larval forms of insects of the order Coleoptera and/or Diptera, characterized in that it comprises: at least one breeding line (14) for breeding insects for laying feed thereon and a flow-through feed heating and/or cooling system (1) with a closed flow of heating-cooling medium for heating/cooling the feed on the breeding line (14). The second object is a method for breeding insects including a step of rearing and/or breeding insects and/or larval forms of insects using a production line according to the invention. A further object is a method for breeding insects using a flow-through feed heating and/or cooling system during the breeding. Another object is the use of a flow-through feed heating and/or cooling system (1) with a closed flow of heating-cooling medium for heating/cooling the feed on the breeding line (14).

An animal cage heating system includes a support structure for support animal cages and a plurality of thermal elements. Each thermal element is configured to provide localized temperature adjustment to one of the animal cages, and each thermal element adjusts the temperature of an animal cage independent of temperature adjustment provided to other animal cages.

A ventilation apparatus for ventilating a building. The ventilation apparatus comprises a casing comprising: a cavity for housing a removable heat-exchange cartridge; a service door providing access to the cavity; a primary and secondary pathways fluidly connecting the inside of the budding to the outside of the budding, wherein the primary pathway and the secondary pathway cross the cavity along about perpendicular axes; a primary ventilator for forcing an airflow in the budding through the primary pathway; and a controllable secondary ventilator for forcing a controllable airflow through the secondary pathway. The ventilation apparatus, when the casing houses the heat-exchange cartridge, has the primary ventilator forcing an inflow of air through the primary pathway, and (ii) the controllable second ventilator for controllably forcing either an outflow or an inflow of air through the secondary pathway. The ventilation apparatus, without heat-exchange cartridge, has only inflow(s) forced through the pathway(s).

A thermal support for animals and method of use thereof is provided. The thermal support comprises a first portion, a strap portion, and a thermal insert. The first portion comprises a flexible fabric configured to conform to at least a portion of the animal. The first portion comprises an opening configured to receive the animal and a shape configured to support the animal when received by the opening. The first portion comprises a pocket configured to contact the animal when received by the opening. The strap portion is configured to enable lifting of the first portion. The thermal insert is configured to be heated and/or cooled. The thermal insert is removably positioned in the pocket of the first portion such that the thermal insert can transfer heat to or from the animal when received by the opening and when heated and/or cooled.

A henhouse includes a gable, a sidewall, and a roof. An inner chamber parallel to the sidewall is provided in the middle of the henhouse. The inner chamber includes an inner wall parallel to the sidewall and an inner roof. A partition is provided between the sidewall and the inner wall. An air inlet plate is provided between the two inner walls located below the inner roof. A pressure chamber is formed between the inner roof and the air inlet plate. A premixing chamber is formed between the inner roof and the roof. A plurality of fans and air inlet windows are uniformly provided on the inner roof. A plurality of air inlet holes and small inlet windows are uniformly provided on the air inlet plate. A plurality of wet curtains and an air vent are provided on the sidewall. A plurality of air outlet slots are uniformly provided on the inner wall.

A temperature-controlled pet bed system includes an electrically powered cooling unit. The cooling unit has a compressor, a condenser, a refrigerant metering device, and an evaporator that are fluidly coupled together to allow a refrigerant to flow through the cooling unit in a refrigeration cycle. A pet bed assembly of the system is configured to rest upon a support surface. The pet bed assembly has an upper bed pad containing or being configured to contain a heat sink liquid to facilitate dissipation of heat and/or cold within the upper bed pad to avoid concentrated areas of hot and/or cold from forming on the upper bed pad. The pet bed assembly further includes a lower bed support that supports the upper bed pad. The lower bed support contains the evaporator of the cooling unit. The evaporator is positioned adjacent to and below the upper bed pad so that heat is transferred between the upper bed pad and the evaporator to facilitate cooling of the upper bed pad.

In a configuration, a protective enclosure for an animal and method of making is disclosed. The protective enclosure may include a floor system and a plurality of wall systems that may define an internal portion of the protective enclosure. A first electrical heating element may be disposed within the floor system or one of the wall systems. At least one wall electrical heating element may be disposed within the at least one wall system of the plurality of wall systems. The first electrical heating element and the at least one wall electrical heating element may be powered by electricity and may be configured to direct heat inwardly from the floor system or the at least one wall system to increase temperature inside the internal portion of the protective enclosure.

One or more techniques and/or apparatuses are disclosed to provide for the reflection of electromagnetic waves from an infrared heater in an enclosed structure. The infrared heater is placed off-center in the enclosed structure and an asymmetrical reflector disproportionally reflects the electromagnetic waves to the far side of the enclosed structure to evenly heat the enclosed structure. The infrared heater and asymmetrical reflector can be used to evenly heat poultry within the enclosed structure to promote uniform eating and conversion of food to muscle mass.

Disclosed is a self-adaptive precise ventilation system for a livestock and poultry house. The system comprises an air pipe, an adjusting assembly, a camera shooting assembly, air flow test pieces and a controller; the air pipe and the air flow test pieces are all arranged above fence areas, the camera shooting assembly is installed on one side of each of the air flow test pieces, and the adjusting assembly is connected together with the air pipe through connecting ropes; a plurality of air supply outlets are formed in the air pipe, and each air supply outlet is provided with a valve; and the camera shooting assembly monitors the air flow conditions in the livestock and poultry house and the information of in-fence areas, and transmits the them to the controller so as to determine the opening degrees and the orientations of the air supply outlets and realize precise air supply.
