Deep water source cooling (DWCS) or deep water air cooling is a form of air cooling for process and comfort space cooling which uses a renewable, large body of naturally cold water as a heat sink. It uses water at a constant 277-283°Kelvin (or 4-10°Celcius)[1] or less which it withdraws from deep areas within lakes, oceans, aquifers and rivers and is pumped through the primary side of a heat exchanger. On the secondary side of the heat exhchanger, cooled water is produced. [2]
Advantages
Deep water source cooling has several advantages:
- It is a very energy efficient method of cooling renewable energy alternative to It uses deep ocean water to provide air conditioning to coastal residential and commercial regions. DWSC uses only 1/10th of the average energy required by conventional cooler systems. [3]
- DWSC does not use any ozondepleting refridgerant. This is still an important feature, despite the fact that smaller/less expensive ecologic cooling devices too exist.
Disadvantages
Several disadvantages are also present:
- DWSC requires the presence of a (fairly) large and deep water quantity in the surroundings. To obtain water in the 3-6°C range, a depth of 66 meters is required. [4]
- The set-up of a DWCS system is expensive and labour-intensive. The system also requires a great amount of source material for the construction and placement. For example the pipes alone can range several hundreds of meters when placed next to one another.
