Help me design and calculate a refrigeration system to cool down a hydroponic liquid in a cooler box. The design would be like in the sketch of the attached files. The inner diameter of the cooler box is 38(L) x 23(W) x 22(H)cm and the outer diameter is L46 cm x W32 cm x H27 cm.
Can you:
- find the cooling load needed to cool down a 16 litre of water at a constant flow rate of 1 litre/minute so that the temperature could maintain 12°C when it flows out of the outlet plug drain below the cooler box.
- Determine the suitable size and height for 4 plug drain to be position at each side of the cooler box, so that the flow rate could achieve 0.25 litre/minute for each of the plug drain. (Flow rate: 0.25litre/minute X 4 = 1 litre/minute)
- determine the right length, the number of coils, and pressure of the copper coil (as an evaporator to be submerged in the 16-litre water) so that it could achieve the cooling load needed to cool down the water to 12°C.
(Guide: Set evaporator pressure such that the saturated temperature of the refrigerant is 15°C below inlet temperature of water [Find inlet water temperature = heat from the atmosphere (30°C) + heat gain during the pump delivery]
- conduct fluid dynamic analysis on the connecting pipe to determine the pump power and the diameter of the delivering pipe.
- Set pressure of condenser of refrigeration plant such that the saturated refrigerant temperature is about 12 degrees C above atmospheric temperature.
-Conduct heat transfer analysis at Hydroponic Liquid and the Refrigerant in the evaporator to determine the flow rate of refrigerant.
-Calculate the power of compressor that operates between condenser and evaporator pressures.
-Determine the size of air-cooled condenser.
-Determine the size of the expansion valve.

I want to build a building, designed for the sole purpose of researching psychedelic chemicals and allowing people a safe place to trip.
Note: This project won’t be rushed, and ideally everyone that helps with it, should have some psychedelic experience. The building will most likely be built in Brazil, where the majority of psychedelics are legal, but If we get the approval of the usa government, we will start in the usa. Eventually though my vision is to have centers in every country and every state that allow for safe, and responsible psychedelic adventures!

Hi, I would like to offer you my project. That is more practical project as viral for about 20 hours and is not urgent. We have small seed packages which needs to be filled with culinary herb seeds.
All what is necessary for work you would receive to your address. If you are interested, we can discuss all details.
