Hot water mixing valve with failure detection

Номер: US20120037095A1
Автор: Samuel Vincent DuPlessis
Принадлежит: General Electric Co

A mixing valve comprises a housing including first and second inlet passages and a third outlet passage. The first passage is connectable in a high temperature fluid supply line. The second passage is connectable with a low temperature fluid supply. The third passage selectively communicates with the first and second passages. A valve assembly is mounted within the housing. The valve assembly includes a thermostat element and a valve body actuatable by the thermostat element. The thermostat element is contactable thermally by the high temperature fluid passing through the first passage. The valve body is operable under the influence of the thermostat element to regulate flow of low temperature fluid and provide a mix ratio of high temperature fluid and low temperature fluid that results in a mixed fluid having a selected temperature flowing out of the third passage. The mixing valve is adapted to provide feedback to a consumer of a failure condition.

A distribution valve controls a distribution ratio of a heat transfer medium between a hot water supply path including a heat exchanger for hot water supply and a beating circulation path through which the heat transfer medium is supplied to a heating terminal. A bypass flow rate control valve controls a bypass ratio which is a ratio of a flow rate of low temperature water introduced into a bypass pipe that bypasses the heat exchanger for hot water supply to a flow rate of low temperature water introduced into a water inlet pipe. The bypass ratio is regulated so that a hot water temperature detected by a temperature sensor reaches a hot water target temperature. During a simultaneous operation of hot water supply and heating, the distribution valve is controlled so that, when a bypass ratio is low, a distribution ratio is higher than when a bypass ratio is high. 1.

In a heating and hot water supply apparatus, a heat exchanger for hot water supply includes a primary-side path and a secondary-side path. A bypass path branches from a heating circulation path and is configured such that a heat transfer medium heated by a heating device flows through the primary-side path without passing through a heating terminal when hot water supply operation is performed and then joins the heating circulation path again. A control unit controls a flow rate regulating valve so that a hot water flow rate does not exceed a reference limit flow rate when hot water supply operation is performed. The reference limit flow rate is set on the basis of the smaller one between a maximum heating capacity of the heating device and a heating capacity of the heating device at which an output temperature of the heated heat transfer medium reaches an upper limit temperature. 1.

One method involves the user of an electrically charged bare wire to heat fluids passing over the bare wire. As fluid in this method is passed directly over the bare wire itself, the water is heated at an extremely high rate. However, bare wire elements are susceptible to damage when dry fired or operated under low pressure. In other words, fluid must be continually present and flowing using ...
