City Multi Hybrid VRF

Hydro Branch Controller

CMB-WM108-1016V-AA/AB

The Hybrid VRF is part of the CITY MULTI product range, which consists of VRF air conditioning units that use refrigerant between the outdoor unit and the Hydro Branch Controller (HBC), and water between the Branch Controller and the indoor units, designed for medium to large scale applications.

AS/NZS 5149 compliant

The Hybrid VRF is compliant with AS/NZS 5149, as no refrigerant is used in inhabited spaces, thus eliminating the need for leak detection systems in occupied spaces.

Better air temperature regulation

Circulating water in the fan coil network allows better air temperature regulation, ensuring a comfortable user experience.

Phased installation

It is simple to install and can be installed in stages, allowing for phased and scalable installations.

Plate Heat Exchanger

HBC has two plate heat exchangers inside. These components transfer the energy from the refrigerant circuit to the closed water loop to the indoor units. These plate heat exchangers can operate interdependently in heating or cooling as required for simultaneous operation.

Pump

Pump

Each of the plate heat exchangers has a DC inverter driven pump. These pumps circulate the water in the closed water loop system to the indoor units. The Valve Block controls the flow rate from the pumps.

Unique technology

Hybrid CITY MULTI exchanges heat between refrigerant and water using our unique HBC, which can reduce the amount of refrigerant in the outdoor unit and keep the piping in the indoor space refrigerant-free.

Valve Block

The valve block has two features. Firstly, it chooses between the two flow headers (selecting heating or cooling). Secondly, it controls the water flow to the indoor units for the required capacity.
