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.
Claims24
A dual air and liquid evaporator, comprising:
- an air cooling section including an evaporator coil having a tube configured to receive refrigerant that changes phase to remove heat energy from an air flow;
- and
- a liquid cooling section, including an evaporator coil having an process tube and an outer tube, the inner tube configured to receive a liquid flow, the outer tube configured to receive refrigerant that changes phase to remove heat energy from the air flow and the liquid flow through one or more stub tubes coupled to the outer tube of the liquid cooling section and configured to be rotated to provide an offset from other tubes of the liquid cooling section,
- where the refrigerant provided to the air cooling section evaporator coil and the refrigerant provided to the liquid cooling section evaporator coil are separately controlled, and
- where the air cooling section evaporator coil and the liquid cooling section evaporator coil are housed in a common frame.

A dual mass cooling system, comprising:
- a fan to configured to generate an air flow;
- a pump configured to generate a liquid flow;
- and
- a dual evaporator, including:
- a first section including an evaporator coil having a tube configured to receive a first refrigerant flow that absorbs heat from the air flow, and
- a second section including an evaporator coil having an inner tube and an outer tube, the inner tube configured to receive the liquid flow, the outer tube configured to receive a second refrigerant flow that absorbs heat from the air flow and the liquid flow through one or more stub tubes coupled to the outer tube of the second section and configured to be rotated to provide an offset from other tubes of the second section,
- where the first refrigerant flow and the second refrigerant flow are separately controlled.
