Most hot water use in plastics processing is for personal use and process use is generally low. Despite this, hot water can be quite costly and the chance to reduce energy use and costs by simple good practice should not be missed. As with lighting and heating, the use of good controls ...
The first thing you must do is deciding what type of hot water system to install. A full time hot water recirculation system could be a big project since you must run a water pipe from the last fixture back to the water heater inlet. If the plumbing in your home has major branch circu...
12. The apparatus of claim 6 wherein the recirculation means comprise: pump means for circulating water through the recirculation means; and, differential thermostatic means having thermostatic elements in each of the reservoirs and being operably connected to the pump means for actuating said pump ...
It is still another object of the present invention to provide a solar hot water heating system wherein water is recirculated between solar collectors and a storage tank and wherein temperature sensors develop control signals for initiating or terminating such recirculation. ...

1 . A combined hot water and air heating and conditioning system 2 comprising: (a) a first heat exchanger 6 comprising an inlet adapted to receive at least one of a fluid supply 80 and a recirculation flow 82, an outlet adapted to provide at least one of an output flow and said reci...
1 for the basic process flow diagram for the invention. As shown in the figure, the invention is an analytical method for the thermal limit in a transient event regarding fuel refill in a boiling water reactor. To prevent the transient event during operation of a boiling water reactor to ...
This slag will be sent back to the fuel storage (30) to be feed back into the system; this loop is what previously has been called the first stream. The cooled exhaust gas will then continue into the scrubber (40) where water will be sprayed on the gas at two different points. The ...
Also, the boiling of water to produce steam provides the desirable constant condensing temperature at the low viscosity zone below 310 DEG F. The present invention is now discussed in a preferred embodiment in reference to Figure 1. The process streams entering the system are the (1) make-up...
A minimum and maximum relationship for the eddy diffusivity factor were found at Re <2100 and >10,000 for recirculation of hot water to the top of the tank and vertical tubes inletting cold water at the bottom. The root mean square error decreased from >4 ◦C to near 2 ◦C when ...
