Building Eutectic Plate
« on: April 29, 2018, 06:11:00 pm »
Someone sent me this picture of a eutectic plate of possibly six gallons . Many of these plates do not have direct metal to metal temperature contact with refrigerant evaporator tubing. For a eutectic plate to absorb heat as efficiently as a standard thin plate evaporator, the eutectic plate's surface area must be large. Heat is quickly absorbed while eutectic solution is a liquid. Once ice starts forming on refrigerant tubing,the heat flow through the plate solution ice slows down reducing the plates Coefficient Of Performance to less than one over one. When the plate evaporator coils can not be mechanically fastened to the plate's surface the copper tubing, as seen in this picture ,spreads apart and then compresses when the plate lid is welded on. This will improve heat absorption when the compressor is running.
