Refrigerator block is solvent to absorb refrigerant in evaporator. Maintain the required pressure in your refrigerator so that solvent evaporation is always at the lowest temperature. Simultaneously compress the cold vapor from the condenser pressure to push it into the condenser. Now I turn the refrigerator block into a powerful steam pump and water pump.
