The heat absorbed by the condenser water in a refrigerating plant is greatest under conditions of low evaporative temperature and high condenser temperature. When the evaporator operates at low temperatures, the refrigerant absorbs heat from the environment or the medium being cooled, which translates to higher heat absorption.

Simultaneously, having a high condenser temperature means that the refrigerant is under considerable pressure when it moves to the condenser from the evaporator. This scenario restricts the refrigerant from releasing its absorbed heat effectively. As a result, the refrigerant exits the condenser at a higher energy level, demanding more heat extraction from the condenser water to maintain the refrigerating cycle. Consequently, this setup causes the condenser to absorb a greater amount of heat from the refrigerant, resulting in higher thermal loads.

In contrast, conditions such as high evaporative temperature and low condenser temperature would lead to less heat being absorbed since the refrigerant would release its energy more efficiently under low pressure and temperature scenarios. Similarly, while medium evaporative and normal condenser temperatures may offer some efficiency, they do not reach the extremes that result in maximum heat exchange. Lastly, high ambient temperature and low condenser pressure would also not enhance heat absorption, as reduced pressure leads to decreased boiling points and subsequently lower thermal
