The Samsung DVM S system has been developed to enhance comfort and reduce energy consumption by utilizing variable-refrigerant flow technology. Both heat pump and heat recovery (simultaneous heating and cooling) systems can support up to 60 indoor units on a single refrigerant system. Indoor units are available in a variety of designs and capacities to suit both room usage, size, and load. The outdoor units are powered by the manufacturer’s inverter scroll compressors with vapor injection. A wide range of controlling options is available to choose from.
