Gulp Fish - cooling and purifying

Gulp Fish is interesting because it can clean and cool polluted water. At the same time it is very unlucky - the English-language wiki does not say a word about its cooling ability, and the Russian-language wiki has outdated information. Let's look into it.

Gulp Fish (for short, hereafter Pacu) absorbs water not only through the cage up, down, to the right, to the left, but also diagonally. It excretes pure water, in portions of 2 kg with a temperature slightly higher its body temperature. "Slightly higher" depends on Pacu's temperature and the temperature of the water she swallowed.

That water Pacu swallowed exchanges temperature with the liquid Pacu is in. Sooner or later, the water surrounding the Pacu will get warmer than the temperature allowed for it (the comfortable range is -30...+5°C), which will dramatically reduce the chance to lay the same egg and lay a normal Pacu egg - the farm will stall.



To reduce the transfer of heat from the dirty water it swallowed, it is worth putting Pacu not in water (heat transfer 0.609), but in ethanol (heat transfer 0.171). The idea is not new, several authors have already used it.

Description
Polluted water with a temperature from 15 to 95°C is fed to the inlet of the circuit. The output is clean water with the following temperatures:

These figures are true for a small amount of water - about 2 kg/s - about how much the average colony needs for farms. For most builds (e.g. Electrolyzer), the water does not need to be cooled.

The maximum volume of water that this circuit is capable of cooling is 10 kg/s - this is the flow capacity of the pipe. You would need to put 50 Pacu (10000/200) in the circuit, since each one cleans 200 g/s of water.

This will narrow the operating temperature range at the inlet to about 40...95°C. If lower - water will be released with a temperature below 0°C and immediately freeze as ice. The scheme can be adapted to work with low temperatures, but there is no sense in it - it is easier to use a conventional Water Sieve.

Automatics, conveyors

 * Thermosensor <4°C
 * Hydrosensor >1010 kg
 * Lower Conveyor Loader - Gulp Fish egg only
 * Top Conveyor Loader - everything else

Thermosensor will start water circulation if ethanol temperature drops below 4°C to prevent ice formation.

Only the upper Auto-sweeper can reach the lower Loader of the conveyor. Its job is to carry the Gulp Fish Eggs to the Conveyor Chute, out the door. This way they won't interfere with the Gulp Fish. The upper Loader is used to take everything else out of the circuit: fillets, shells, common and tropical Pacu eggs. A mesh tile restricts the top Auto-sweeper access to the eggs at the chute.

Startup
Create a vacuum in the chamber (the Airflow Tile must be in a vacuum - this ensures that the ethanol is thermally insulated from the hot water). Pour 900 kg of ethanol and water so that the water covers the ethanol. The excess water will be pumped out by a pump. The default water temperature is 27°C.

Pacu in the scheme of feed in small portions of 3-5 fish, otherwise the ethanol heating circuit can not cope and fish will begin to release ice instead of water. The ice will melt sooner or later, but a large release of water can displace the ethanol and it will have to be topped up.

Farm
Even if the Gulp Fish is kept at optimal temperature, there is still a chance (about 19%) that it will lay an egg of a different species. Therefore, the scheme can only work in conjunction with the Pacu farm. Gulp Fish eggs must be delivered to the scheme and all other eggs must be taken out of the scheme.

An approximate view of the scheme and farm is shown in the screenshot. Essentially, 1 Conveyor Loader has been added to Pacu Farm, which is used to move Gulp Fish eggs into the cooling scheme. This does not change the logic of the main farm.
