Hitachi Cold-Resistant Renewal Type Heating and Cooling Switchable Model
Hitachi Global Life Solutions
A cold region renewal type "Cold-Resistant" that utilizes existing piping.
Overview A renewal type that can utilize existing piping without worrying about the cold. It demonstrates high heating performance even at low outdoor temperatures. Shortened renewal work process without piping cleaning A unique renewal filter is built into the outdoor unit, allowing for the removal of moisture and oxidized components of the existing refrigerant oil in the existing piping. Additionally, by using the renewal kit (optional), it eliminates the need for cleaning the existing piping even if the compressor of the existing unit is faulty, thus shortening the renewal work process. Equipped with automatic determination function for additional refrigerant filling It features a dedicated charge port and a refrigerant quantity determination algorithm based on subcooling detection, automatically determining the appropriate refrigerant amount. Maximum piping length from the first branch is 60m, saving construction costs by consolidating multiple refrigerant systems The maximum piping length from the first branch to the indoor unit has been extended to 60m. This makes it easier to consolidate multiple refrigerant systems near the outdoor unit. For more details, please contact us.
