The units, in the use configuration, are disposed to overlie the user and include a plurality of emitters that direct infrared energy toward the user's body.

Systems may include a heater including a plurality of heating elements that may include a first heating element configured to generate heat based on a first current, and a second heating element configured to generate heat based on a second current. Systems may further include an electromagnetic (EM) radiation reducing device configured to cancel electromagnetic emissions from the heater. The EM radiation reducing device may include a first EM radiation reduction element positioned adjacent to a first side of the heater, and a second EM radiation reduction element positioned adjacent to a second side of the heater, where the first and second EM radiation reduction elements have geometries configured based, at least in part, on the heater.

The subject of the present invention is a sauna storage heater and a sauna cabin which uses the sauna storage heater. The sauna heater can be operated independently in terms of energy without a connection to the power grid and without the use of fuels such as wood, gas, or oil. A heat storage fluid is used in the sauna storage heater, the boiling temperature of which fluid is over 100° C. at normal pressure. The heat output from the sauna storage heater is regulated by means of flaps on air inlet and air outlet openings.

The present invention relates to a heat cabin with hot air extraction. In particular, it relates to a heat cabin (10) which is equipped with a heat supply and an exhaust air system, wherein the heat cabin (10) comprises support beams (42) and cladding panels (40) and the cladding panels (40) are aligned perpendicular to a wall or ceiling normal, and the exhaust air system comprises exhaust air openings (50) in the cladding panels (40), whose shape is determined by the support beams (42) and/or the cladding panels (40) and which have no through passage parallel to the wall or ceiling normal. Furthermore, it relates to a method for operating a heat cabin.

Provided is a tower-type outdoor air cleaning apparatus that is disposed outside a facility that performs air cleaning, cleans outside air, and supplies the cleaned air, including: a tower body unit that is disposed away from the facility on one side of the facility, is provided in a tower type with a double-wall structure, in which fomentation is performed inward, air is filtered and suctioned, and is exhausted; an air supply unit that is provided above the tower body unit, in which air is supplied through an upper portion thereof and air flows in through a side portion at a plurality of locations of an outer circumference thereof and is mixed with the air supplied through the upper portion; an air ventilation filter unit that is disposed inside the air supply unit and the tower body unit, filters the mixed air supplied from the air supply unit to be supplied to the facility connected thereto, and exhausts the air circulated in the facility to the outside; a fomentation facility unit that is disposed inside the tower body unit and generates heat and electricity using solar energy for use in fomentation; and a control unit that is connected to the air ventilation filter unit and the fomentation facility unit to control the amount of air supplied by the air supply unit through the air ventilation filter unit, and controls production and transfer of heat and electricity using solar energy in the fomentation facility unit.

Systems may include a heater including a plurality of heating elements that may include a first heating element configured to generate heat based on a first current, and a second heating element configured to generate heat based on a second current. Systems may further include an electromagnetic (EM) radiation reducing device configured to cancel electromagnetic emissions from the heater. The EM radiation reducing device may include a first EM radiation reduction element positioned adjacent to a first side of the heater, and a second EM radiation reduction element positioned adjacent to a second side of the heater, where the first and second EM radiation reduction elements have geometries configured based, at least in part, on the heater.

The mist generating device includes a housing 11 having a water tank 12; a shaft portion 13 provided in the housing and extending in a vertical direction; an impeller 14 disposed on the shaft portion to be rotatable by means of the motor in a horizontal direction about a rotation axis that is the shaft portion; a nozzle 15 for jetting the water in the water tank toward the impeller; and a pump 21 for delivering the water in the water tank to the nozzle. The impeller includes a plurality of blades 14a arranged along a rotation direction of the impeller and configured to collide with the water jetted from the nozzle. The water jetted from the nozzle collides with the blades to thereby smash the water and generate mist.
