A magnetic refrigeration module includes a housing, low and high temperature inflow paths, low and high temperature outflow paths, and first and second intermediate flow paths. The housing houses a magnetic working substance, and forms a flow path. The low and high temperature inflow paths carry heating medium into first and second ends of the flow path. First and second spaces are formed between the first and second ends and the low and high temperature inflow paths. The low and high temperature outflow paths receive the heating medium from the first and second ends of the flow path. The first and second intermediate flow paths communicate with the low and high temperature inflow paths and the first and second spaces. The first and second intermediate flow paths expand heating medium flow from the low and high temperature inflow paths to the first and second spaces.

A solid-state electronic dehumidifier (SSED) to improve the performance, productivity and longevity of small-scale ozone-generating devices. By removing moisture upstream of the ozone generator, the SSED stabilizes the ozone generator's rated ozone output. Reducing moisture content in the process gas (air), increases unit performance, and the lifetime of the ozone-generating cell is increased by reducing nitric acid generation. The system includes an SSED upstream from an ozone generator. The SSED has an outer housing divided into two chambers, a cold side and a hot side, by a dividing panel. The SSED has a cold heat sink located in the cold side and a hot heat sink located in the hot side, with a heat exchange unit secured in the dividing panel in contact with both cold and hot heat sinks. Air flow through the hot and cold sides dehumidifies the air in the cold side and is directed to the ozone generator.

An air purifier apparatus, comprising: a housing comprising an air intake opening to an external environment outside the housing; a plant pot disposed downstream of the air intake, configured to hold soil, and being perforated so as to enable contact between at least some air outside the plant pot and at least some of the soil inside the plant pot; an air purification filter disposed downstream of the plant pot; a fan disposed downstream of the air purification filter; an air outlet disposed downstream of the fan and located in a first compartment of the housing; a dehumidifier disposed in a second compartment of the housing separate from the first compartment and configured to extract water from air interacting with the dehumidifier, the second compartment having an air exchange perforation opening to the external environment; a watering system, configured to circulate water located inside the housing to the plant pot.

An air blower includes: a panel (3); a frame member (5) arranged to surround the panel (3) and having a blowout port (13a, 13b, 13c, 13d, 13e, 13f, 13g) of air formed therein; and a fan (11a, 11b, 11c, 11d, 11e, 11f, 30) that sends air to the blowout port (13a, 13b, 13c, 13d, 13e, 13f, 13g). The frame member (5) produces airflows that are blown out from at least three directions and collide with each other, thereby producing an air current going forward to the panel (3).

A heating and cooling apparatus is disclosed that combines a PTC heating element with a fan, and a combination of a cooling device aided by a thermoelectric cooling device to provide heating, passive air conditioning, and air circulation. The heating and cooling apparatus can include a condensation trap, a collection container, and an ozone generator for collecting and purifying the condensate. In addition, this apparatus provides the additional function of serving as an air purification system operating either in combination with the heating/cooling functions or as an independent air purifier.

A system and methods for photovoltaic phase change material assisted thermoelectric air cooling and heating of a building includes a photovoltaic phase change material wall unit which is cooled by absorption of heat by a phase change material attached to the photovoltaic wall unit; a photovoltaic phase change material roof unit which converts solar radiation into electric energy; Peltier based thermoelectric units configured to heat and cool air streams passing through an air duct; and Seebeck effect based thermoelectric units which convert a temperature gradient into thermoelectric power. A hot air stream in the air duct is directed to an air duct on a roof of the building and a cold air stream from the first air duct is circulated into the building interior to achieve thermal comfort.

A foothold including a thermoelectric module includes a module housing in which a dissipation fan and a thermoelectric element are provided, and a blowing portion disposed at a first side of the module housing and having a blowing fan. Further, the thermoelectric module further includes a dissipation heat sink installed over the dissipation fan, and a cover provided at the upper portion of the module housing and having a top surface on which the user's feet may be placed.

An improved locker seat includes a pair of spaced-apart upstanding sidewalls having a pair of lateral edges. A generally horizontal seat is disposed between the lateral edges of the sidewalls. In a first mode, an air source is connected to an airway formed within the seat to create an airflow. The airflow from the air source creates a first temperature differential to cool the seat. In a second mode, an external or internal heat source provides heat to a top surface of the seat, creating a second temperature differential to heat the seat. The first and second temperature differential are distributed across the top surface of the seat. The seat is hinged to be movable about the hinge between an open and a closed position.

A temperature control layer, for example for an interior trim of a vehicle or a vehicle part is disclosed. The temperature control layer includes an areal thermoelectrical temperature control arrangement with at least one thermoelectrical element and an air extraction arrangement with at least one air extraction duct. The at least one air extraction duct leads from an outside of the temperature control layer through the temperature control arrangement to an inside of the temperature control layer.

The disclosure concerns a method for regulating a Peltier element. In a starting step, a starting current is applied to the Peltier element. Subsequently in a cooling step, a surface that is heat-conductively connected to the Peltier element is cooled. In the cooling step, the surface is cooled to a target temperature. After the cooling step in an adjustment step, a maintenance current is applied to the Peltier element. The maintenance current is lower than the starting current.
