Water system efficiency

A system to monitor the efficiency of a recirculating water system, the system comprising:

• a heat exchanger to exchange heat between a cooling tower and an environment to be cooled;
• a plurality of sensors to measure and/or collect data one or more operating parameters of the system;
• a water source to provide makeup water for the cooling tower, and
• a monitoring system configured to
• calculate a key performance indicator of a recirculating water system as a ratio of a theoretical efficiency metric and a measured efficiency metric, wherein the measured efficiency metric is based on a measured rate of water traversing the recirculating water system and measured power data, and the theoretical efficiency metric is based on heat energy data and load data associated with the recirculating water system.

A method comprising:

• receiving, at a monitoring device comprising one or more computing devices:
• heat data corresponding to heat energy of a unit of water associated with a recirculating water system;
• power data corresponding to power being applied to the system;
• and
• load data corresponding to a load associated with the system;
• calculating, at the monitoring device, a measured rate of water traversing the recirculating water system based on the heat data;
• determining, at the monitoring device, a ratio of the power data and the measured rate of water that defines a measure metric;
• determining, at the monitoring device, an efficiency metric of the system by comparing the load data to a data source;
• calculating, at the monitoring device, a key performance indicator of the recirculating water system as a ratio of the efficiency metric and the measured metric;
• and
• outputting, from the monitoring device, to a graphical user interface a representation of the key performance indicator.
