City Multi Hybrid VRF

City Multi Hybrid VRF

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 branch controller, and water between the branch box and the indoor units, designed for medium to large scale applications. Efficiency and reliability are at the very core of the Mitsubishi Electric Hybrid VRF systems.

Comparison against the 4-Pipe System

The HVRF Series contributes to reduced installation work. Because HBC houses the pump, heat exchanger, and other major components, it requires a fewer number of components to be installed, compared to four-pipe chiller systems.

Industry First Technology

The Hybrid CITY MULTI is the industry’s first system which uses refrigerant between the outdoor unit and the HBC (Hybrid Branch Controller), and water between the HBC and the indoor units. The HBC is the most unique part in this system and allows heat exchange between refrigerant and water.

Mild Air Conditioning

Achieved by a water system between the HBC and the indoor units, the water temperature is generally very stable all year round. The Hybrid CITY MULTI will supply milder off coil temperatures.

Simultaneous Cooling/Heating Operation

Provides air conditioning corresponding to various needs. With the 2-pipe system, direction of refrigerant flow will not reverse when the main mode changes. The compressor does not need to stop when the mode changes. This allows comfortable air conditioning during mild ambient conditions.
