Abstract
An aircraft cooling system comprises an evaporator, condenser, an accumulator, and a pump system. The evaporator is configured to cool a set of heat loads in an aircraft using a liquid. The liquid forms a vapor in response to cooling the set of heat loads. The condenser is configured to receive the vapor from the evaporator and cool the vapor in which cooling the vapor forms the liquid. The accumulator is configured to receive the liquid from the condenser and store the liquid. The pump system is configured to pump the liquid stored in the accumulator to the evaporator.
Claims23
An aircraft cooling system comprising:
- an evaporator configured to cool a set of heat loads in an aircraft using a first liquid in a liquid loop, wherein a second liquid in a liquid-vapor loop forms a vapor in response to cooling the set of heat loads;
- a condenser configured to receive the vapor from the evaporator and cool the vapor in which cooling the vapor forms the second liquid;
- an accumulator configured to receive the second liquid from the condenser and store the second liquid;
- and
- a pump system comprising a first pump and a second pump, the first pump configured to pump the first liquid in the liquid loop to the set of heat loads and the second pump configured to pump the second liquid stored in the accumulator to the evaporator and pump the second liquid from the condenser to the evaporator.
