Abstract
Devices, systems, and methods are disclosed for cooling using both air and/or liquid cooling sub circuits. A vapor compression cooling system having both an air and liquid cooling sub circuit designed to service high sensible process heat loads that cannot be solely cooled by either liquid or air is provided.
Claims52
A dual air and liquid cooling system comprising:
- a controller;
- a dual air and liquid evaporator having:
- an air cooling section configured to receive refrigerant;
- and
- a liquid cooling section in mechanical communication with the air cooling section and configured to receive refrigerant, the refrigerant operable to change phase in the air and liquid cooling sections to remove heat energy from the air and liquid cooling sections;
- and
- two or more control devices controlled by the controller and coupled to the dual air and liquid evaporator, a first control device of the two or more control devices operable to provide refrigerant to the air cooling section of the dual air and liquid evaporator and responsive to the controller operable to control the phase of the refrigerant in the air cooling section to generate cooled supply air and a second control device of the two or more control elements devices operable to provide the refrigerant to the liquid cooling section of the dual air and liquid evaporator and responsive to the controller operable to control the phase of the refrigerant in the liquid cooling section to generate cooling supply liquid,
- the air cooling section and liquid cooling section being housed in a common casing.
