Abstract:
A fluid tempering system comprising:a storage tank adapted to hold fluid, said storage tank having a cold fluid inlet, a hot fluid outlet and at least one heating element therein to heat fluid held in said storage tank;a cold fluid path receiving cold fluid from a source and delivering cold fluid to said storage tank via said cold fluid inlet;a temperature sensor monitoring the temperature of cold fluid delivered to said storage tank;a mixing zone having a first inlet coupled to said hot fluid outlet via a hot fluid path and a second inlet coupled to said cold fluid path, said mixing zone mixing hot fluid received from said hot fluid path with cold fluid received from said cold fluid path to cool said hot fluid prior to delivery to a distribution system; anda valve responsive to said temperature sensor and controlling the amount of cold fluid delivered to said mixing zone so that the temperature of hot fluid delivered to said distribution system remains generally constant irrespective of fluctuations in the temperature of said cold fluid.
