Outdoor unit
What is
is a three pipe heat recovery system, which means simultaneous
cooling and heating is possible from one system. This is achieved using the three
pipes from the outdoor unit in conjunction with heat recovery boxes. The heat
recovery boxes (or HR boxes) are installed between the outdoor unit and indoor
units, and the refrigerant is distributed to the indoor units in its required state
(depending on whether or not cooling or heating is required). Heat that is
removed from one room can be used elsewhere within the system where it is
required, thus making the even more efficient. The
is available from 8Hp (single module) up to 40Hp (combining multiple outdoor
units together). Up to 40 indoor units can be connected to one system, reducing
installation material cost, and installation time. Combined with the many control
options on offer, the system can offer a total building solution.
