Abstract
This invention is an improvement to the existing reverse osmosis water filtration systems used in under-the-sink and similar commercial applications. This improvement uses a thermally conductive liner that allows an increase of efficiency to heat or cool water within the reverse osmosis system. In addition, it includes a controller that determines the amount of cooling required without contact with the water. The controller provides slow-rate pulse-width modulation of the Peltier-like device to cool, and dependant on room temperature, potentially heat the water within the reverse osmosis system.
Claims4
An improved under-the-sink reverse osmosis water purification system that comprises:
- a) a Peltier-like device, and
- b) a thermally-conductive liner;
- whereby the efficiency of the thermal transfer is increased.
An improved under-the-sink reverse osmosis water purification system that comprises:
- a) a Peltier-like device;
- b) a thermally-conductive liner, and
- c) a slow fixed-rate pulse-width modulated electronic control;
- whereby the temperature of the water within the system is cooled without use of water temperature measuring devices.
An improved under-the-sink reverse osmosis water purification system that comprises:
- a) a Peltier-like device;
- b) a thermally-conductive liner, and
- c) a room temperature measuring means that provides control to determine the proper slow-rate pulse-width control;
- whereby the control will maintain a cool temperature within the system without measuring devices that make contact with the water.
Said improved under-the-sink reverse osmosis water purification system of claim #3 which further includes a reverse polarity means for said Peltier-like device to heat said improved under-the-sink Reverse Osmosis water purification system;
- whereby system will avoid freezing during winter months.
