Super energy-saving precision temperature and humidity air conditioning unit eONE-A05W: Nitto Refrigeration
Nitto Refrigeration Manufacturing Co., Ltd.
[Energy Conservation Award Winner] This is a super energy-efficient precision air conditioning unit. It utilizes patented technology that recovers 100% of heat, reducing running costs by up to 80%.
The precision temperature and humidity air conditioning unit demonstrates its performance in industrial air conditioning systems, all factory spaces where temperature and humidity are precisely managed, and in work processes or evaluation equipment spaces that are sensitive to humidity. It significantly reduces running costs and achieves cost recovery in a short period. - Pioneering 100% heat recovery utilization heating (Patent No. 4593689) - Direct heat source-less - Up to 80% energy savings compared to direct expansion cooling units and electric heater-equipped systems - Achieves precise humidification with a humidifying heater and drip evaporation filter The eONE series won the Minister of Economy, Trade and Industry Award in the 2015 Energy Conservation Grand Prize (Product and Business Model Category). It recovers heat obtained from cooling dehumidification and cooling water and achieves 100% reuse for heating and humidification. Its energy consumption efficiency allows for a significant reduction in power consumption compared to conventional electric heater-equipped units, which was highly evaluated. This is an energy-saving technology that cannot be replicated by traditional [package air conditioner + heater + humidifier] systems.

Detailed information
-
The mechanism of 100% heat recovery utilization. eONE performs humidification using heat recovered from cooling water and reheating using heat recovered from intake air. Additionally, the surplus heat recovered from the intake air (specifically, the input from the compressor) is discharged into the cooling water. Temperature and humidity control is achieved without using any direct heat sources such as electric heaters or boilers.

Internal Structure *The image is of the eONE-A1W. The eONE is an all-in-one refrigeration unit that includes cooling, dehumidifying, heating, and humidifying mechanisms. This allows for efficient 100% recovery and utilization of heat. Additionally, it eliminates the need for various refrigeration units and boilers for cold water heat sources.
-
Case Introduction In the case of A1W that was actually implemented, there was a cost reduction of 48% to 75%. Even with a 48% reduction, the total costs can be recovered from the first year.
