So the term 1/1 and UoAo/UiAi, it is the resistance to heat transfer between water and cooling compounds will have a value equal to the value of thermal resistance of each field in the Manufacturing Setup window. As follows:
Thus, the term 1 / UoAo and 1 / UiAi is resistance to heat transfer between the refrigerant and water combination is equal to the thermal resistance of each of the following combinations.
So the term 1 and / UoAo 1 / UiAi was overall heat transfer resistance between refrigerant and water. Will be equal to the heat resistance of each combination. As follows.
