KXZR – 3 PIPE HEAT RECOVERY
Cooling and Heating
Simultaneous heating and cooling
These heat recovery systems work with 3 interconnecting pipes and therefore are commonly referred to as “3-pipe” systems. These systems offer both heating and cooling in a single indoor unit, based on the room conditions/requirements. The systems incorporate a highly sophisticated air conditioning control for multiple indoor areas, regardless of the cooling or heating needs, for applications where the building orientation (N, S, E, W) may result in a heat increase/loss on different sides of the same building. The range starts from a cooling capacity of 22.4 kW and goes up to 20HP with a cooling capacity of 56.0 kW. The outdoor units can also be combined in “pairs” or in “triple combination”, reaching 60 HP/168.0 kW on a single system.
Heat recovery systems
The interconnection piping system has a unique arrangement with two of the interconnecting pipes passing through an PFD distribution controller and the third tube connected directly to each indoor unit from the main pipe path.
This reduces installation times and the number of braze-welded connections on the site. The PFD distribution controllers are available for single connection or as a 4-way combined PFD connection, with each connected unit characterised by independent cooling or heating.
