Abstract
A shower bath, sink, or other fluid receiving vessel is described wherein heat is reclaimed from the drain fluid to warm the incoming cold water to reduce the amount of hot water which must be mixed in to produce water of the temperature desired for use within the vessel. The improvement consists of a cover pan for collecting the received fluid and depositing it on a particular region of the vessel floor which is contoured to direct the received fluid along a particular channel to a drain. The cold water supply tube is positioned within the channel in contact with the draining fluid. The warmer drain fluid transfers heat energy into the cooler water flowing within the submerged cold water supply tube.
Claims9
A fluid receiving vessel incorporating an energy exchange device for reclaiming heat energy comprising:
- (a) a pan for collecting the received fluid and depositing it on a particular region of
- (b) a contoured floor for directing the flow of the received fluid along a particular channel containing
- (c) tubing positioned within said channel whereby the fluid flowing within said channel is in contact with the exterior surface of said tubing, the said tubing conveying fluid at a temperature different from the received fluid such that there will exist a transfer of heat energy between the fluid flowing within the said channel and the fluid flowing within said tubing, thereby heating or cooling the fluid flowing within the said tubing and reducing the amount of heating or cooling otherwise required in the process utilizing the fluid flowing within the said tubing.
