The present disclosure provides methods for enabling an individual having a cat allergy to have a cat as a pet. Such a method can include quantitatively determining a threshold in the individual for an environmental level of an allergen produced by the cat and selecting a cat or a breed of cat that creates an environmental level of the allergen that is less than the threshold. Additionally, such a method can include lowering the allergens disseminated by the cat by treating the environment inhabited by the cat during a time period where the cat expresses elevated allergens.

A multi-storey animal house includes a multi-storey animal house body with multiple breeding storeys. The breeding storeys include a first breeding storey, a second breeding storey, a third breeding storey, a fourth breeding storey, a first cultivating storey, and a second cultivating storey which are sequentially arranged from top to bottom.

A ventilation and temperature regulation structure for an animal house, comprising a house body and a temperature regulation device with a culture layer, the house body comprising a temperature equalization device and an exhaust gas extraction device, the temperature equalization device includes a temperature equalization passage passing through the culture layer, several ventilation holes are disposed on the side wall of the temperature equalization passage; and an outlet end of the temperature regulation device is connected with the temperature equalization passage. Such technical solution is to provide a temperature regulation structure for an animal house having good ventilation, waste reduction and good effect of temperature regulation.

A ventilator unit has a ventilator housing and at least one ventilator accommodated in the ventilator housing. A first outlet guide apparatus is associated with the ventilator and is arranged in the ventilator housing, wherein the first outlet guide apparatus has first outlet guide vanes distributed circumferentially. A second outlet guide apparatus is correlated with the first outlet guide apparatus and arranged in a flow path of an air stream sucked in by the ventilator. The second outlet guide apparatus is connected to a protective screen. The second outlet guide apparatus has second outlet guide vanes. The second outlet guide apparatus increases the throw of the ventilator unit.

An improved greenhouse structure having sides and a roof to define at least a partially enclosed space, with an interior ceiling section and the interior ceiling section being at least substantially transparent. An air channel is formed between the roof and the interior ceiling section with an air input device in fluid communication with the air channel and the interior ceiling section has one or more openings through it to allow air in the air channel to pass through and into the enclosed growing space to provide a top-down air conditioned effect.

An air purifier (100) includes a control unit (110). The control unit (110) is configured to acquire occupancy information indicating whether or not a person is in a room. The control unit (110) is configured to switch operational control based on a type of pet specified by a user and the occupancy information. When a person is not in the room, the control unit (110) preferably performs operational control to increase an airflow compared to that when a person is in the room.

The device is a hollow enclosure, similar to a hollow tube shape with openings on either end. The openings are covered by a fine screen, to allow air to pass through the center of the device. Further, a small fan is installed in the center of the device, allowing to suck air in from one side, and blow air out of the other side. The device is then placed into a terrarium, vivarium, or similar pet or plant cage to create internal air circulation within the environment.

A pet house accessory with functions of air purification, sterilization and temperature regulation, including a shell, a mounting plate, a thermal conduction device, a semiconductor refrigeration sheet and a sterilization device, wherein a heat dissipating hole is arranged at the center of the bottom of the shell, the thermal conduction device is arranged at the center of the bottom of the mounting plate, the semiconductor refrigeration sheet is fixedly installed at the bottom of the thermal conduction device, and a through hole is defined inside the thermal conduction device. The pet house accessory with functions of air purification, sterilization and temperature regulation provided by the present disclosure is capable of cooling and heating by controlling the semiconductor refrigeration sheet through the control switch to cool down and warm the pet house, and is convenient for pets to live.

A ceiling inlet unit that assists in bringing air into the interior room of a building. The unit has a housing providing an opening to the attic of the building, the housing having movable blades with brush borders on the ends, pivotally mounted with a continuous hinge in the housing with seals to minimize air leakage when the blades are closed. The housing is designed in such a way to provide optimal air mixing situations through available cross-sectional area at different ventilation stages. The blades are designed to maximize air jet throw during lower ventilation stages, and provide superior total airflow during maximum ventilation stages.
