Achieving ventilation in a safe and comfortable sealed space by using a sensible heat exchanger to retain the cooling heat of the air conditioner and prevent the return of contaminated air.
Air conditioners in offices and similar spaces generally do not have ventilation functions due to their circulation method, which recirculates indoor air. During the COVID-19 pandemic, it is necessary to regularly open windows for ventilation. As a result, during ventilation, the inflow of outside air can be uncomfortable, and the load on the air conditioner increases significantly. Fresh Eco Change is a ventilation air conditioning unit that allows for comfortable ventilation while remaining sealed. When expelling indoor air, it stores cold heat in a sensible heat exchanger, and conversely, when taking in outside air, it absorbs that cold heat, enabling comfortable ventilation while minimizing indoor cold heat loss. Essentially, the exhaust and intake do not come into direct contact within the unit, ensuring that viruses and odors do not return indoors, providing peace of mind. There are also models equipped with medium-performance filters that are effective against pollen. Fresh Eco Change is a ventilation air conditioning unit designed for comfortable ventilation even in a sealed state, looking ahead to the post-COVID era.

basic information
■ Ventilation is possible while keeping rooms like those with air conditioning sealed. ■ Eliminates discomfort from temperature changes when outside air flows in during ventilation. ■ Uses a sensible heat exchanger (cross-flow plate type) without a refrigeration unit. ■ Stores the cooling heat of the exhausted indoor air in the sensible heat exchanger and transfers that cooling heat to the intake air from outside. ■ Comfortable ventilation is possible even in rooms where windows and doors cannot be opened. ■ Equipped with a heater, so there is no worry about freezing or low-temperature air being supplied in winter. ■ Exhaust and intake do not come into contact, ensuring no return of viruses or odors, providing peace of mind. ■ Models equipped with medium-performance filters effective against pollen are also available (model number ending in NF). ■ Can be installed as an add-on outdoors. ■ Comes with an indoor remote control (20m cable). ■ Two ventilation airflow rates of 500m³/h and 250m³/h (during high operation).
