Water Tempering System

摘要

A water tempering system comprising a mixing tank located downstream from the main hot water storage tank, the mixing tank receiving a supply of hot water at a first temperature and a supply of cold water, the hot water and cold water supplies mixing within the mixing tank to provide a source of tempered hot water at a reduced, second temperature that is discharged from the mixing tank for distribution and use within an overall system. The amount of cold water directed to the mixing tank is controlled by a variable frequency drive pump which can adjust depending on system demands to ensure that sufficient cold water is directed to the mixing tank to ensure adequate mixing occurs to bring the temperature of the hot water to the second reduced temperature even during periods of low demand.

主权项

1. A water tempering system comprising:
a mixing tank having a first inlet for receiving fluid from a first water supply line at a first temperature, a second inlet for receiving fluid from a second water supply line, and a first outlet for discharging fluid from said mixing tank and delivering said fluid via a third water supply line at a predetermined second temperature; a variable frequency drive pump fluidly coupled to said second inlet for controlling the flow of fluid to said mixing tank through said second inlet; a control valve arranged in fluid communication with said variable frequency drive pump for controlling flow to said variable frequency drive pump; a control system for receiving temperature data associated with at least said third water supply line and transmitting said data for operably adjusting said variable frequency drive pump and said control valve to one of a set of predetermined operating conditions.
