Problems solved by technology

This has the disadvantage that the waste heat of the compression refrigerating machine additionally loads the cabin air conditioning system, since the air conditioning system has to cool the additional heat load in the pressurized cabin
The extra weight borne by the high power design results in higher fuel consumption and reduces available payload
Moreover, the compression-type refrigerator is more difficult to install in the aircraft due to the large installation space occupied by the high-power compressor, evaporator and condenser

Embodiment Construction

[0031] figure 1 An aircraft liquid cooling system 4 in an aircraft 2 is shown together with an auxiliary cooling device 100 . The aircraft liquid cooling system 4 comprises a refrigeration device 6 , a control device 8 , a pump and reservoir 14 , a first line 18 , a second line 16 and a first valve 20 . In flight, the refrigeration device 6 cools the liquid coolant delivered to the line 10 . The liquid coolant cools the heat load 12 . A pump 14 supplies coolant through the cooling circuit. Reservoir 14 provides additional coolant in the event of a leak. Since the first valve 20 between the first line 16 and the second line 18 is opened in flight, liquid coolant circulates in the cooling circuit.

[0032] The heat loads 12 may be food carts in the galley, food or drink areas in the galley, flight control computers, entertainment systems, and / or cabin areas to be individually air-conditioned. The cabin area to be individually air-conditioned may be first class and / or the ar...

Abstract

An auxiliary cooling device (100) is designed to be operated outside an aircraft (2) and comprises a source of cold adapted to cool a refrigerant to a desired low temperature, an auxiliary cooling device outlet (104), connected to the source of cold, which can be connected to a refrigerant supply connection (28) of an aircraft liquid cooling system (4) to release a refrigerant that has been cooled by the source of cold to a desired low temperature to the aircraft liquid cooling system (4), and an auxiliary cooling device inlet (102), connected to the source of cold, which can be connected to a refrigerant release connection (26) of the aircraft liquid cooling system (4) to absorb refrigerant that has been heated by heat absorption of a heat load (12) in the aircraft (2).

Description

technical field [0001] The invention relates to an external auxiliary cooling device for cooling elements and / or cabin regions of an aircraft on the ground, and to an aircraft liquid cooling system interacting with the external auxiliary cooling device. Background technique [0002] In aircraft, the use of central liquid cooling systems is increasing. A typical liquid cooling system includes a chiller delivering a cold liquid coolant. Liquid coolant is delivered to one or more heat loads in the aircraft by means of a network of pipes. Multiple heat loads connected in series and / or parallel can be supplied with liquid coolant. The liquid coolant returns to the chiller after cooling the heat load(s), so that it circulates permanently in a closed circuit. A liquid cooling system has the advantage that the lines used to transport the liquid coolant can have a much thinner design than in cooling systems using a gaseous fluid (such as air) as the coolant, because the liquid coo...
