A helicopter air conditioning and refrigeration system

Abstract

The invention discloses a helicopter air conditioner refrigeration system. The system comprises a soft start unit, an interlocking unit and a circulation unit; the soft start unit is used for controlling the work current and rotating speed which are obtained when a compressor is started, speed increase of the work current obtained when the compressor starts is lowered, and the speed increase of the rotating speed obtained when the compressor starts is lowered; the interlocking unit is used for controlling an air conditioner to work to stagger an onboard heavy component; the circulation unit isused for conducting air duct arrangement by means of an air supply device and a ventilating duct of a helicopter, and circulating refrigeration is achieved. Accordingly, by adopting a compressor softstart technology, impact of air conditioner starting to an onboard power supply can be lowered, by adopting an interlocking scheme between onboard heavy load electric parts and air conditioner electric parts, and the problem that an electricity supply between the air conditioner electric parts and the onboard heavy load electric parts is insufficient is solved; according to the characteristics ofthe helicopter, by means of an original ventilation duct, an air outlet and an air supply device, the problems that helicopter air passage arrangement is difficult, the air volume is insufficient, the refrigerating capacity is insufficient, and the weight is high are solved.

Description

technical field [0001] The invention relates to the technical field of aircraft environmental control, in particular to a helicopter air conditioning and refrigeration system. Background technique [0002] The existing helicopter air-conditioning and refrigeration systems mainly have the following problems: 1. The air-conditioning start-up current has too much impact on the on-board power supply, which affects the stability of the on-board power supply, poses a threat to the power consumption of on-board equipment, and even causes some equipment to fail to work; 2. Simultaneous work of on-board large-load components and air conditioners in a specific environment results in insufficient power supply for the helicopter, which affects the normal operation of the main functional components; After the passage, there are problems such as insufficient air volume and insufficient cooling effect, but the overall weight of the air conditioner still reaches 50-60kg, which reduces the e...

Problems solved by technology

[0004] In view of this, the purpose of the present invention is to overcome the deficiencies in the prior art, to provide a helicopter air-conditioning and refrigeration system, to solve the impact of air-conditioning start-up on the on-board power supply, to solve the gap between the power consumption of air-conditioning and the power consumption of airborne large-load components. Insufficient power supply solves the problems of difficult helicopter air duct layout, insufficient air volume, insufficient cooling capacity and heavy weight
