This system allows for simultaneous cooling and heating operation using one refrigerant system, with high efficiency or space-saving options.
Piping can be connected by using either separation tubes or headers to suit a variety of project designs.
Our advanced refrigerant control technology allows us to achieve a total refrigerant piping length of up to 1000m.
Efficiency is improved with the highly efficient motor with sophisticated drive control. Additionally, the DC fan motor exhibits low noise output.
High heat exchanger efficiency is achieved by using an internal projection shape with double pipe construction.
When multiple outdoor units are connected, a sophisticated operation is performed by each compressor. Rather than running one compressor at full load and distributing refrigerant to one heat exchanger, this control method operates all compressors at part load and distributes refrigerant to all of the heat exchangers allowing for the overall system efficiency to be improved.
Heat exchanger efficiency is significantly improved by the introduction of a new 4-face heat exchanger with an increased effective surface area.
1 to 12 port RB units are availabe to offer greater flexibility with refrigerant piping work for various floor layouts and building structures.
