Know how much power is consumed by key HVAC components.
Wet Differential Pressure… Is used to monitor the differential pressure between chilled water supply and return, as well as condenser water supply and return. Controls bypass valves to regulate flow based on demand. Provides a secondary proof of flow by monitoring the differential between supply and return air.
Gauge Pressure… Is used to monitor pressure in the condenser and evaporator units to determine the ultimate pressure on the line. Using a gauge pressure product on both the supply and return will provide the data needed for the BMS to calculate the differential pressure.
High or low pressure readings may be an indicator of a mechanical failure in the system like a leak, pump failure, locked rotor, a clog, etc.
Current Sensors… Monitor run status on all pump motors. Can be used to detect on / off status, locked rotor, and overall pump status for proof of function / water flow. Proof of functionality. No need to manually check each pump. (If current is flowing, the pump is working.)
Temperature Sensors… Used to monitor temp for chilled water loop and condenser water loop, helps to control the valve that determines water recirculation speed. Helps to determine pump speed, how much water needs to be returned, and is a main control point for the system.
Flow Meter… Monitors water flow in the supply and return lines of the chilled water loop and condenser water loop. Provides both proof of flow and measures usage.
BTU Meter… Is a flow meter combined with temperature sensors and can be used for energy measurements. The output is BTUs not a flow rate – its output is a measurement of the energy consumed by the chiller. It is also used to check the efficiency of the chiller. Clogs, excessive ice, malfunctioning pump, humidity changes, compressor cycling issues, can all be the causes of chiller inefficiency.
