PD Meters/Pumps Inquiry (采购产品): PD Meters/Pumps Hello: I have a requirement to now to acquire/develop a “specialized” pump/meter technology that would be suitable for an advanced "off-peak electricity" water heater approach. I have obtained a U.S. Patent regarding this approach that would enable extra-hot water to be generated in a storage tank (at night time, where low-cost electricity prices are available) and then delivered at a safe, non-scalding temperature during the daytime. The heart of the invention is a positive-displacement "splitter" that resides upstream of the water heater: this splitter, consisting of a mechanically-linked pair of PD pumps (or PD meters), would cause the cold supply water (upstream of the storage tank) to be split into two "fixed-ratio" streams. That is, when hot water is demanded by the end user, one stream of cold water would go directly to the water heater tank (to force hot water out of the top of the tank); the other stream would be cold bypass water which would mix downstream of the tank with the hot water so as to provide safe, non-scalding water to the end user. This is illustrated by the diagram and information: http://www.hawtwater.com/ourinvention.htm The main functional requirements for this "splitter" device would be the provision of a relatively constant mixing (or splitting) ratio between the two streams of water so as to supply the tempered hot water at a relatively constant temperature to the end user (given that the tank hot water would remain constant in temperature with time and the service water would also not change much in temperature over the seasons). Additional background information is also contained in www.hawtwater.com . A main safety consideration is that, in the event of a "jamming" of the splitter device due to any reason, the actual flow of water through the device should be very small. This advanced water heater approach is a completely passive technology (unlike conventional thermostatic anti-scald valves) that works entirely on the cold side of the water heater (again, unlike conventional thermostatic anti-scald valves) to reliably provide safe, non-scalding water to the end user. Hopefully, the “splitter” device can be constructed of (less-expensive) non-metallic materials that would function well for long periods of time and operation in cold water environments. We aim to prove out proto-types of this approach and then to soon enter into the annual 11,000,000 water heater replacement market in North America. Your comments and advice that might be able to assist me with the acquisition/design of an appropriate splitter device will be very much appreciated. Thanks in advance for your help.
