Hitachi Flex Multi Heat and Cool Simultaneously Type
Hitachi Global Life Solutions
Flex Multi, which achieves high energy efficiency by reusing waste heat and operating heating and cooling simultaneously.
Overview Flex Multi for simultaneous heating and cooling compatible with various building air conditioning systems Energy-saving performance through heat recovery operation (during simultaneous heating and cooling operation) In a simultaneous heating and cooling system, the waste heat generated during cooling operation can be reused as heating energy, allowing for a reduction in the power required for the compressor. Particularly during low-load conditions, such as transitional periods, the closer the ratio of cooling to heating capacity approaches 50%:50%, the greater the energy-saving effect. The Flex Multi (simultaneous heating and cooling type) adopts technology aimed at improving operational efficiency during low-load operation, similar to that of the cooling and heating switch type. This has achieved a high efficiency COP of up to 7.8 for the high-efficiency TGX series (model 335) and up to 7.6 for the high-efficiency TSX series (model 450). [Energy-saving feature] Hitachi's new technology achieves high COP with the same installation area as conventional units. For more details, please contact us.
