CO2-Based Heat Pump for Water Purification
The process has a number of benefits over existing water purification methods: Cost-effective in comparison to other methods as the device consumes less power, comparable to other household appliances. Increased efficiency in terms of volume of purified water produced as compared to other domestic water purifying systems. Eliminates the requirement of a separate refrigerator or cooling process making the output water ready for immediate consumption. Enhanced mobility of the system is facilitated by its small size and portable nature to be used in areas struck by natural disasters where drinking water is unavailable. Flexibility to be used areas lacking electricity by the use of alternative fuels like natural gas and biomass by configuring compressors to be connected directly to external heating sources.
The most direct application of the technology is in the areas of commercial and domestic water purification including residential consumption, foods and beverages industry and pharmaceuticals. The global water industry is more than a $400 billion market, not including about 1 billion people still lacking access to safe drinking water. The U.S. is the worldΓÇÖs largest consumer for purified and bottled water; the domestic market for drinking water exceeded $1.3 billion in 2006 and is expected to surpass $2.1 billion by 2011 at a growth rate of 11%. Theworldwide demand for drinking water is projected to reach $10 billion by the same year which demonstrates a huge available market for the technology.
Stage of Development:The technology is at an advanced stage of development. It permits flexibility in configuration of design and operation parameters to alter the temperature of input/output water, power consumption and efficiency factor to meet any requirements.Future Development:The invention can be developed to serve as a versatile technology in order to meet specific requirements as proposed.
