EffHVAC is an Internet-based chiller, boiler, and heat exchanger efficiency tool that can be used to run your equipment at maximum efficiency at all times with advanced diagnostics and fault detection, the company states. The diagnostics can determine sensor, gauge, or data entry problems; flow rate problems; high or low refrigerant levels; fouling or scaling; noncondensable gases; refrigerant stacking; plugged or restricted flow; and cycles of concentration problems. Once a fault has been detected, detailed troubleshooting guidelines are available to help fix the problem. No software is required, only an Internet connection.
