To respond to the needs for the promotion of energy saving in drying processes in industrial fields, Mitsubishi Heavy Industries Thermal Systems, Ltd. developed "Neppu-ton," a hot wind generator using a high-efficiency air-source heat pump, which enables the supply of hot wind of 60°C to 90°C. "Neppu-ton" adopts the separate system with an outdoor unit and an indoor unit separately installed, which allows the indoor unit to be installed directly in a process requiring hot wind and reduces the installation cost. We conducted a demonstration test in the actual environment to verify the energy-saving performance and drying quality under actual use conditions. As a result, we confirmed that there was no problem in its use as a drying system. By promoting the use of "Neppu-ton" in industrial fields, we will reduce energy usage and CO2 emissions and promote global environmental protection.
