A temperature control system for a semiconductor processing facility
includes a common cooling unit for controlling the temperature of a
cooling fluid and multiple remote temperature control modules that
separately control temperatures of multiple process components. The
temperature control modules are near process components and include a
circulation loop for cooling fluid from the common cooling unit and a
circulation loop for a heat transfer fluid received from a component. A
heat exchanger within the temperature control module allows heat transfer
between heat transfer fluid and cooling fluid, thereby cooling the
component. A heat source may also be within the temperature control
module to heat the heat transfer fluid and the component. The cooling
unit may be a refrigeration unit that provides compressed refrigerant to
the temperature control modules which may include an upstream thermal
expansion valve and a downstream refrigerant flow control valve that form
an evaporation chamber.
