Cooling system of airplane air conditioning generator set

Abstract

The invention provides a cooling system of an airplane air conditioning generator set, heat dissipation performance of an airplane air conditioning bus is improved, and continuous working time of the airplane air conditioning bus is prolonged. The cooling system of the airplane air conditioning generator set comprises a water tank, a water pump, a spray device and a control switch, the water tank is connected with an evaporator of a refrigerating system and collects condensate water of the evaporator, the water pump is connected with the water tank and pumps the collected condensate water in the water tank to the spray device, the spray device is positioned above a generator set radiator and sprays the condensate water conveyed by the water pump to the generator set radiator, and the control switch is connected with the water pump and controls the water pump to work.

Description

technical field [0001] The invention belongs to the field of aviation special support vehicles, and relates to a cooling system for an aircraft air conditioning generator set. Background technique [0002] At present, there is no unified standard for the design of the heat dissipation effect of aircraft air-conditioning vehicles in my country. The current design of aircraft air-conditioning vehicles is basically that the continuous working time of aircraft air-conditioning vehicles is no more than 4 hours when the outdoor temperature is 30°C, but this is far from meeting the needs of scientific research and flight tests. The requirements for continuous long-term work of air-conditioned vehicles are mainly due to: [0003] The diesel generator set of the aircraft air-conditioning vehicle has 4 cooling fans to cool the refrigeration system. With the continuous long-term operation of the refrigeration system, the heat generated by the generator set and the refrigeration system w...

[0002] At present, there is no unified standard for the design of the heat dissipation effect of aircraft air-conditioning vehicles in my country. The current design of aircraft air-conditioning vehicles is basically that the continuous working time of aircraft air-conditioning vehicles is no more than 4 hours when the outdoor temperature is 30°C, but this is far from meeting the needs of scientific research and flight tests. The requirements for continuous long-term work of air-conditioned vehicles are mainly due to:

[0003] The diesel generator set of the aircraft air-conditioned vehicle has 4 cooling fans to cool the refrigeration system. With the continuous long-term operation of the refrigeration system, the heat generated by the generator set and the refrigeration system will be discharged into the equipment cabin. The cabin space is limited, and the heat cannot be removed in time, resulting in the temperature in the equipment cabin rising continuously, the control system reports a failure, the compressor condensing fan enters self-locking protection, the thermal relay is disconnected, and the air-conditioned vehicle stops working;
