The Challenge with VRF Metering
Many multi-space building managers need to measure the energy consumption of every space for the purpose of improving operational performance and accurately billing tenants. With VRF/VRV systems, where most energy is consumed by the condensers, there is a challenge regarding the correct distribution of the condenser’s energy between the different air handlers.
The Solution
WattMeters measure the actual condenser power consumption and push this data continuously over Modbus RTU to CoolMaster or CoolMasterPro, which then transfers the periodic readings to CoolAutomation’s Cloud for analysis. The cloud-based application then breaks the overall consumption to each of the individual indoor units, based on CoolAutomation’s unique algorithm that accurately calculates the actual operational ratio and kWh of each indoor unit.
The CoolAutomation VRF Power Distribution solution allows you to bill your tenants accurately – by the actual operational demand of each indoor unit.
The solution requires a field supplied WattMeter with a Modbus RTU interface, and can support multiple VRF systems and mixed VRF brand topologies.
