The MS Box is the key component to the Lennox VRF Heat Recovery systems. It offers flexible installation configurations in 2-,4- and 6-port models, with each port featuring a dedicated subcooling circuit. Integral hot gas bypass control maintains minimum suction pressure during part load operation.
- Integrated Suction Pressure Protection—An integrated hot gas bypass valve provides an additional measure of compressor protection by helping maintain minimum suction pressure during low load conditions.
- Heat Recovery—MS box operation allows condensed liquid refrigerant to flow from an indoor unit in the heating mode into an indoor unit in the cooling mode, reducing waste heat rejected at the condensing unit and improving the overall operational efficiency of the heat recovery system.
