About This Product

■Environmental conservation/energy saving products

"For the future of people and the earth" We propose the heat exchanger "Thermocoil®" to promote energy conservation by recovering waste heat to solve problems such as global warming and acid rain.

■What is “Thermocoil®”?

Thermocoil® is a heat exchanger unit in which a large number of heat pipes with secondary heat transfer surfaces (fins) are arranged in a staggered pattern and divided into two sections by a partition plate.The heat pipes pass through the partition. I am. Compared to conventional heat exchangers, it is possible to increase the secondary heat transfer area by adding fins on both the supply and exhaust sides, making it more compact and reducing pressure loss. This Thermocoil® unit is normally ducted so that the supply and exhaust flow is counter-current. In the unit, the exhaust side of the heat pipe is heated by high-temperature exhaust gas, and the evaporation of the working fluid creates a steam flow, which moves to the air supply side of the heat pipe, increasing the wall surface temperature and eventually heating the supply air. It will be.

■Features

・A compact heat exchanger with high performance and low pressure loss. ・No running costs are required for heat recovery. ・Clean hot air can be obtained with extremely little mixing of air supply and exhaust air. - Heat can be recovered efficiently even if the temperature difference is small. - Has excellent durability. ・Each heat pipe has no driving part, so there is no mechanical failure. ・Each heat pipe is independent from each other, providing a wide degree of freedom in operation. - Materials can be selected according to conditions, and corrosion-resistant materials can be combined. ・Dimensions and performance can be selected according to the installation location, and installation is easy by measuring.

■Calculation conditions

・Fuel used: Petroleum (kerosene), calorific value 9,580Whr/L ・Unit price: 68 yen/L ・Equipment operating time: 2,100 hours/year

■Effect calculation

Oil savings = recovered heat (W) ÷ calorific value (Whr/L) × operating time (hr/year) × oil (kerosene) unit price (yen/kg) ≒ 5.05 million yen/year
