Abstract

A heat exchanger for waste water comprises a tank containing and communicating domestic waste water in heat exchange relationship with a supply of fresh cold water. The tank comprises an outlet which communicates waste water from the bottom of the tank to the top and into a drain so that the tank is always full of waste water. Fresh water may be supplied into another tank disposed inside the tank for waste water, into a coiled pipe disposed inside the tank for waste water (fig 2), into a further tank communicating with a coiled pipe wrapped around the further tank with both being disposed inside the tank for waste water (fig 3). The fresh water may also communicate with a further heat exchanger disposed inside the tank for waste water and used in combination with a heat pump (fig 4). The heat exchanger may have a removable cover to permit cleaning and inspection. All pipe connections may be located above the waste water level so that during a leak, contamination of the fresh water is avoided. The waste water may be from a bath, shower, washing machine or dishwasher.

Description

SPECIFICATION
Domestic/Institutional Heat Exchaneer
Description of the invention.
This invention consists in the use of a specially designed heat exchanger to remove waste heat Tom a hot/warm liquid and transfer it by conduction, radiation and convection to another fluid which is at a lower temperature and requires heating. The process involved will require in addition to the above mentioned heat exchanger a number of specially adapted components to control the flow of the fluids involved in order to extract the maximum possible amount of heat from the waste fluid.
The design of the heat exchanger can/will van depending on its size, its application and the method of production. Sketches will demonstrate widely different methods of construction of the heat exchanger.,h.ich will accommodate variations in the volume of fluid to be treated, the amount of time required for heat transfer, and the method of construction which will help to reduce the cost of the equipment. In addition to the heat exchanger itself for which there are intrinsic limitations, the principal one L: À1__ a_. _r __. :_ A_____ 1__^ _ _ I_._____ _. _ or_ _ __ 111 Lll"L Lll llVW V1 11 1b U=llUllL All LllC Flit U111111 between the two fluids and will stop hen the two fluids have reached an equilibrium temperature which is between the temperature of the original hotlwann and cold fluids.
In order to increase the useable temperature differential this invention includes the incorporation of an additional feature which artificially raises the temperature of the not waste fluid and allows the waste fluid lo be rejected at a lower temperature.
This is accomplished by incorporating an HEAT PUMP which raises the temperature of the hot fluid in the heat exchanger and allows the waste fluid to be rejected at a temperature below that of the fluid being heated.
This is one of the advantages of the heat pump which under certain conditions is more efficient for heat transfer than primary heat sources such as combustion or electrical resistance heating. ?

Claims (4)

1. The heat exchanger, as described in the specification, is provided with a siphon drain pipe that allows the waste fluid container to be filled to a predetermined level and to be kept at that level (covering t1- IC t-10 4.rai-li coinpi,rerlts)' elect 'L11L travel alas Scan reactlcd, 'tl-lC introduction of additional waste fluid automatically ejects the coolest waste fluid from the bottom of the tank by gravity flow.
2. A siphon pipe transfers the cooled waste fluid from the bottom of the waste fluid tank to an exterior receptacle or piping system.
(This receptacle or piping system is not part of this patent application).
3. The unit cover is located above the level of the waste fluid and is removable in order to allow the extraction of the heat transfer components for cleaning and inspection purposes.
4. All mechanical pipe connections are located above the level of the waste fluid so that in the eventuality of leakage due to a loose pipe connection, the clean fluid will not come onto contact with the waste fluid and be contaminated by it.
