MRVIII-RC 3-pipe system with heat recovery is a new development of Haier Corporation, which makes it possible to increase the energy efficiency of the presented split air equipment.
Unlike the traditional 2-pipe system, in which the indoor units can work fully either in cooling or heating mode, a 3-pipe system with heat recovery makes it possible to use the indoor units in mixed modes, i.e. some of them can be used for cooling and other ones for heating while using the same outdoor unit.
To distribute the refrigerant flows and to deliver the necessary airflows to the indoor unit, the MRVIII-RC system is equipped with additional devices-VP-units, i.e. distribution units.
