Free Cooling

The point of these schemes is that the heat generated by the AT is enough to run the turbine and the circuit would not need energy from the outside.

The AT with water in the circuit generates 585 kDTU/s, and the turbine at maximum power consumes 878 kDTU/s. Even with supercoolant in the loop (heat release of 1182 kDTE/s), the duration of the AT would be 74%, energy consumption of 888 watts, which is more than the turbine produces (850 watts). Scheme will be at a disadvantage in terms of power.

The idea suggested by Kharnath is that the water leaving the turbine is heated by a liquid heater to 125°C. This approach is more effective, because Liquid tepidizer (LT) produces more heat (4064 kDTE) than AT, but consumes less (960 W vs. 1200 W)

Two circuits were assembled:


 * 1) In the AT circuit, water (polluted), with a cooling capacity of 99.5 kDTE/s.
 * 2) In the AT circuit, super coolant. Excluding heat exchanger losses, the circuit cools at 1182 kDTE/s, and produces about 185 watts of energy.

For the skeptics, both circuits retain full performance in the safe loading field.

AT with water in the loop
Water coming out of the turbine cools the turbine itself, heating a little, then the flow is divided by a valve into two pipes, 1000 g in each and goes to the chamber with AT. Limitation of water volume to 1000 g is necessary so that water heated to 125°C would not break the pipe.

The AT circuit may contain water (t freezing -0.6°C) or polluted water (t freezing -20.6°C). The duration of the LT was 6%, the TWR 17%, which resulted in a consumption of only 261 watts. Steam under the turbine heated up to 128°С, which resulted in production of about 264 W.

Automatics, materials

 * Thermosensor LT: <124°C
 * Timer: 1 green, 15 red
 * Battery: 80-90%
 * Pipe thermosensor: > -5°C (if polluted water), >15°C (if regular water)
 * AT, battery, LT, valve: steel
 * Water in all chambers before start-up, 200 kg/cell

AT with supercoolant
Same principle, but there are 2 turbines and some supercoolant in the AT circuit. AT works all the time (thermosensor as reinsurance). The task was to know to what temperature the steam will heat up, that's why there is no AT shutdown when the water temperature in the circuit is low. It can easily be added.

Timer setting: 1 green, 5 red. The duration of operation of LT was 12%. Consumption of the circuit is 1315 W, energy production by the turbines is about 1500 W. Total circuit generates about 185 W, and cools to the full power of the AT.
