water top up. Having a low maintenance cost(electrical bill) is another advantage. Thanks... |

very good attempt
but may i ask this question to those who have relative smaller tanks like 2ft and below. are you using fans at the moment and find topping up a hassle even thought the fans are very effective in reducing temps at a low cost? question: is topping up REALLY a hassle? imho, unless you are upgrading to a chiller, just stick to fans. another solution would be to get an auto-top up system. |

for a 1 feet tank, a medium size fan running at 4watt can effectively bring the temperature down by 2-4 degrees or even more.. on hot days, the highest temperature I ever recorded is 26.5 and on cold raining days, it can be as low as 24.5 degrees..
running at 24hrs per day, electricity bill is around $0.61 monthly.. as for water, I only need to top up water with 1 medium size tub everyday.. |

from my personal experience, I guess when the temperature is higher on hot days, fan will introduce more evaporation thus I was able to attain more than 4 degrees off the ambient temperature.. on rainy days, when ambient temperature is around 26 degrees, the water temperature differences is only around 2 degree as evaporation is not so effective then.. thus I tend to top up more water on hot days and lesser on rainy days.. not sure is this the same for those who are using fan..

Defying the laws of thermodynamics as in - making a system cooler than the ambient temperature while minimising evaporation with a fan and a radiator.

You are right with the explanation. It is impossible to achieve a lower temp than the external ambient temp using a pure heat exchanger unless it is in an aircon enivronment. There is also another method by adding on an expansion chamber in the radiator system similar to the aircon system. Heat lost due to sudden expansion. Sounds familiar?
