One option is to equip one or more parallel chillers with the refrigerant migration cycle (Figure 43). This essentially turns the chiller into a shell-and- tube heat exchanger run-around loop.

There are times when well, river, or lake water will be pumped through the condenser. In these cases, examine the cost of pumping the water versus the benefit of more water passing through the condenser. The environmental limitations imposed by local codes are another consideration. Some locales will not allow well water to be dumped after being used. Other local authorities limit the maximum water temperature that may be returned to a
