Heating X-L Pipe
- Heating X-L PIPE
- An innovative heating technology which improves heating efficiency using special heat medium and expansion pressure by heating the heating wire in a closed X-L pipe without a boiler or circulating motor which is the medium for floor heating.
(Patent No. 08305703)
Operating principle of Heating X-L Pipe
Nucleate boiling and film boiling that occur when heating in a closed space
– Nucleate Boiling
Nucleate boiling is a phenomenon where air bubbles occur independently from fine air bubble nuclei at the side of heat transfer by beginning from the temperature slightly above the saturation temperature when heating liquid for boiling. When the temperature at the side of heat transfer rises, occurrence of air bubble and mixing of breakaways increase, greatly increasing heat transfer coefficient to maximize energy saving and efficiency.
– Film Boiling
Film boiling is a phenomenon where steam bubbles occur on the entire heating side in the shape of the side when heating a liquid for boiling.
It occurs when the heating capacity is very high. When heating in a closed space, film boiling leads to heat storage effect from insulation effect of gas (depends on temperature but approximately 0.0347 kcal/mh℃) in the heating plate that has been heated for a certain period of time. The heat energy (Kcal) generated during this process maintains the certain temperature for longer time due to heat storage effect of internal gas, contributing to saving energy.
Structure of Heating X-L Pipe
Strong points of Heating X-L Pipe
- Economic feasibility
-
- Electric energy is turned into heat and used for 100% room heating.
- Saves heat cost by over 70% for the area of the same size compared to oil heating (Nucleate boiling)
- Does not require facility piping, saving construction cost and construction period
- Heat medium filled in piping and heat storage effect of plastered layer enable heating for a long time using a small amount of energy.
- Safety
-
- Our shielding facility is free of electromagnetic waves and harmless to human body
- ● Seals conductor and heat medium in a double layer, having no risk of leakage or explosion
(Utility model No. 0442474) - ● Enhances safety by performing double insulation using silicone with heatproof temperature of 200℃ and Teflon with heatproof temperature of 200℃ (domestic insulation condition: Over 0.4mΩ,company inspection condition: Over 20mΩ)
- ● Utilizes device for absorbing expansion pressure inside piping, preventing liquid from leaking or accelerator from bursting
- Functionality
-
- Does not require boiler room, having advantage in utilization of space
- If product defect occurs, a repair can be done by opening check box without disassembling the floor. (Patent No. 0805703)
- Heating can be replaced only by inserting heating wires into existing heating pipes
- The traditional floor ondol heating emits far-infrared radiation and anion, and the warm air makes the indoor air clean. (Far-infrared radiation 0.891, anion 142)
- Durability
-
- External installation of a cold lead and pressure-acceptance system prevents malfunction.
- The system is moveless after construction.
- It cannot be frozen to -20℃ by inserting insulation material to prevent heat storage and freezing in pipe
