<p>PURPOSE: Heating facilities having a heating device having a low-temperature heating function, far-infrared radiation and local heating control characteristics are provided. The heating facilities enable local heating of a greenhouse and easy replacement of a heating element, prevent burn injuries by heating devices and reduce energy consumption. CONSTITUTION: The low-temperature heating device(1a) comprises: a body case(400) made of heat-resistant resin; a ceramic case containing a far infrared rays emitting material; a heating element(100) having a stick or ring shape, low-temperature thermal properties of 90deg.C or less and electrical power consumption of 50 to 1,000 Watt; a 3-wavelength fluorescent lamp; a temperature control circuit board(30); a temperature sensing and control part(70); and a power supply socket part(500) for connecting to a general bulb socket. In an agricultural greenhouse, a heating device having about 10 to 25 watt per unit area of 1m¬2 is installed. For an example, a heating device of 200 to 2,000 watt is installed at each upper space which is divided into an area of about 5 to 20m¬2 in a poultry barn.</p> |
