Abstract

The invention relates to an airplane ground air-conditioning vehicle utilizing exhaust waste heat of a diesel engine, an inlet of a fan is connected with an air inlet mounted on the wall surface of a compartment body through an air passage, an outlet of the fan is connected with a refrigeration heat exchanger by the air passage, the refrigeration heat exchanger is connected with an exhaust waste heat recovery heat exchanger of the diesel engine, and the exhaust waste heat recovery heat exchanger of the diesel engine is connected with two interfaces of air supply pipes through a variable diameter air passage; and an exhaust port of a diesel generator is connected with an exhaust muffler, and the outlet of the exhaust muffler is connected with an exhaust three-way control valve. The airplane ground air-conditioning vehicle adopts the recovery of the waste heat contained in exhaust of the diesel engine for heating air, thereby replacing the practice of heating the air in the electric heating way or the air source heat pump way in the traditional airplane ground air-conditioning vehicle; and the airplane ground air-conditioning vehicle has the advantages of recovering and utilizing a large amount of heat energy which is discharged into the environment and is not utilized in the traditional air supply heating method, realizing the obvious energy-saving effect and simultaneously reducing the installed capacity of a power supply power system of the airplane ground air-conditioning vehicle.

Description

technical field

[0001] The invention relates to a ground air-conditioning vehicle matched with an aircraft, in particular to an aircraft ground air-conditioning vehicle utilizing exhaust waste heat of a diesel engine. Background technique

[0002] The aircraft ground air-conditioning vehicle is a kind of aircraft ground support equipment. When the existing aircraft ground air-conditioning vehicle needs to heat the air supply in winter, it generally uses electric heating or air source heat pump to heat the air. For the air source heat pump method, the prominent problem is poor environmental adaptability. When the outdoor ambient temperature is low, the heating capacity drops rapidly, which cannot meet the needs of aircraft support, and the outdoor heat exchanger needs to be defrosted every time. , unable to achieve continuous heating. For the electric heating method, the prominent problem is the low heating efficiency, the equipment power load does not match under the winter...
