Lets talk about chillers!

[Creetin]

all this going on about chillers are making me confused but gian oredi.... can someone let me in on the different technologies used, brand+pricing, maintainence (read some need to use coolant)?

like i know teco is good but ex? eido not sure, hailea is cheap.....?

and wat is h/p? wat does this mean?

[hongqixian]

h/p = horsepower.

Creetin... you are not supposed to post question in Produce Reviews.

Am moving this thread to the Marine Aquarium Equipment forum.

Teco chillers are suppose to be maintenance free in the sense that they don't require gas top up unless there is a leak.

Chillers for aquarium use are either conventional compressor type or peltier type. I don't exactly know how peltier works, best search the net for answers.

When a low voltage DC power source is applied to a thermoelectric module, heat can be moved through the module from one side to the other. One module face is therefore cooled while the opposite face is simultaneously heated. This phenomenon can also be reversed. That is, a change in the polarity of the voltage causes heat to move in the opposite direction. This thermal energy process was first observed in 1834 by Jean Peltier, a French watchmaker and part-time physicist, who was investigating thermal energy flows between dissimilar metal junctions. Today's thermoelectric modules, first introduced in about 1960, make use of modern semiconductor technology substituting doped semiconductor material for the dissimilar metals used in early thermoelectric experiments.

Thermoelectric modules are solid-state components that cool a system by drawing heat from one side of the module to the other through the application of a small electrical charge. In contrast, mechanical refrigeration units use a compressor to circulate a refrigerant that absorbs heat throughout a system. While both systems function according to the same thermodynamic principles, thermoelectric modules are small, lightweight solid state devices with no moving parts to wear out. Thus they can often be included within the equipment or even become an integral part of cooled components. In addition, reversing the polarity of the applied DC voltage reverses the direction of the heating and cooling, a feature that makes them ideal for controlling temperature or in processes which require both heating and cooling of a medium.
