It should from the beginning we make explicit that the criterion for the particular manufacture was NOT only exclusively the solution of problem of temperature, but at the same time and a live exercise for the students that are in the department of cooling school. For this the reason and the manufacture should have been visible in all the stages. The initial thought was to be possible to put serpantj'na in in water antj' comes out the water and it is frozen outside by the aquarium. A solution would be we put instead of coper, stainless pipe in order to we in do not have problem with metal in the aquarium. After him we searched, it was realised that also the stainless pipe after some time oxejdw'netaj and late or fast would have problem. Ejk. 1 The next thought hence were to make a small aquarium in in the aquarium, that will be frozen the water that will contain and the refrigeration will be transported in mainly water of aquarium. Hence the water that would be found in in this small aquarium would be come by no means in contact with water of aquarium after the internal aquarium would be found little more tally by the level of water of mainly aquarium. For ayto'.ton the aim we made a "aquarium" with dimensions 50 H 50 H 8 cm (Ejk.1). This was stuck regularly with silicone and became from pane ?rj (4 mms). Him we placed in such a way that his no side does not lean in pane of aquarium in order to we do not have by no means losses of temperature. Ejk. 2 In this it should it is sunk serpantj'na by coper that after calculations of experts would be supposed to have length 7 metres. The next work therefore was her manufacture, something that required enough effort particularly from the Virtuous Sja'ho that undertook this work. The result appears in picture 2. Ejk. 3 In order to it is supported, we put a cooling unit with force of 1/4 Ip (Ejk.3). Initially we considered that it was not enough possible in order to it freezes the 450 litres of aquarium. Then however it showed that rather him it accomplishes. In the end became a table where was placed the electronic thermostat, a safety that supports all the electric parts of aquarium and certain other elements that appear analytic below. 1 Digital thermostat. 2 Cable of benefit of tendency of (electric current) in the cooling unit. 3 Cable of benefit of tendency for any use. 4 Sensory thermostat. It measures the temperature of aquarium. 5 Cable of benefit of tendency in the table. 6 Lamp of interruption of operation of cooling unit. 7 Rele' of activation of cooling unit. 8 Automatic safety. 9 Rele' of escape. 10 General switch. 11 Hronodjako'ptis of control of lighting. 12 Ske'pasma of aquarium the 10 it interrupts the benefit of tendency in all the table. 9 And 8 protect mainly the user and then the instruments from short-circuit or escape of current. The 4 it measures the temperature of water of aquarium and it sends the price in the thermostat (1), which him compares with the limits of prices that him we have given. If it is inside limits it gives simply command in the lamp (6) to turn on and us him to make acquaintance (pleonasm). If it passes the pa'vw limit of temperature of thermostat (26,3 ?C) it gives command the thermostat in the rele' (7), which with his line it puts in operation the cooling unit. The operation of unit is continued up to the temperature of aquarium becomes equal with the down limit of temperature of thermostat (26 ?C) A photograph with serpantj'na in in the aquarium. The reception is not also best... a) Calculations for the manufacture cooling by the professors Virtuous Sja'ho and Panagiotis Ri'ga. V) The hour of regulations and control of unit. Initially was regulated the thermostat it begins mote'r in the 27 ?C and him it stops in the 26 ?C. Then however we saw that in order to she lowers this one degree the cooling unit should works constantly for above one hour, with probability the summertime that will be the temperatures tallest this time to grow also other. Now it has been regulated it begins in the 26,3 ?C and it stops in the 26 ?C. With this regulation finally it needs roughly 30 thinly in order to it goes to the 26 ?C and afterwards in order to lose water of these 3/10 of degree need much more a long time. Rather will remain there the regulation, except and if it needs is decreased still more a lot the difference, that is to say in the 2/10 of degree. The subject substantially is it does not need works the cooling unit for a long time possessed, after the objective to us is covered in every case.
How about a small mod to this DIY concept. Put a large fan onto the tank, and have the ATO water directly inside the fridge. Not technically a chiller but it would make a significant difference.
Ok its a great idea if you allready have the fridge with freezer , use the fridge for ur beer and get a stainless steel hose, copper is better for cooling (joking dont use copper line).. coil it up in the freezer the more feet the better (like the way you would make grapa), as long as the water is flowing it wont freeze, Diy chiller there you go
