Mitsubishi Multi Head Split System

Alternatively, there is the PUMY CITY MULTI VRV series. Unlike the MXZ Series with multiple connections to the outdoor unit, the PUMY Series features just one refrigeration connection. This is connected from the outdoor unit to a multi-port branch box within your ceiling space or optionally to an external enclosure. Multiple refrigeration connections are connected to the branch box to indoor units.

With multiple branch boxes and junctions up to 12 indoor units can be connected and operated simultaneously depending on capacity requirements, with a selection of different types of indoor units from wall mounted to ceiling cassette and more. This means you can design an air conditioning system to suit many unique individual applications.

Multi Split System vs Ducted

With these systems Mitsubishi Electric provide total energy efficiency, performance and control to home cooling and heating usually only found in large commercial applications. They are perfect for any situation, from a few rooms through to a whole-home renovation. These sophisticated systems give you more control over the temperatures in your home and do it better than ducted air conditioning. How?

Better Filtration

Conventional ducted systems force a large volume of air through long duct runs and usually only one standard return air filter.

With a multi-split ductless system, you get sophisticated filtration at every room or area to reduce contaminants such as allergens, viruses, and bacteria from the air. This combination of filters provides a healthier breathing environment for the home and higher indoor air quality.

Better Temperature Control

With a single ducted system, you would traditionally have only one set thermostat at the return air to control and set the temperature for the entire home.

 In comparison, with a ductless multi-split system, all indoor systems detect temperature fluctuations within each zone it is installed in and automatically adjusts performance for ultimate comfort in any room. All indoor models feature a return air sensor that constantly monitors and maintains room temperature.

More Efficient Energy Transfer

Ducted air systems require large fan coil units to push air long distances through bulky ductwork. This ductwork often runs through unhealthy, unconditioned ceiling spaces. The average energy lost through central ductwork is 20-30% and even more when ductwork is designed and installed with little care. The time taken to test ducting, seal leak spots, retest and seal again is a time consuming and costly process. Besides the power required to run the larger fan coil, the ductwork itself can have a limited distribution of capacity throughout a home.

Refrigerant cycles through small sealed evacuated insulated copper pipes, distributing capacity effortlessly to each zone. With smaller capacity indoor units to deliver the conditioned air to each zone more efficiently with little to no energy loss. Because of lower heating and cooling loads this leads to smaller and more efficient HVAC systems with tailored comfort and the added bonus of advanced, superior control.
