Refrigeration air conditioner for helicopter

Abstract

The invention relates to a refrigeration air conditioner for a helicopter, which comprises an electric control cabinet, a compressor, an air cooling condenser, a condenser fan, an evaporator and an air feeder, wherein the compressor is connected with the air cooling condenser; the compressor, the air cooling condenser and the condenser fan are not arranged in a driving cab of the helicopter; and the evaporator and the air feeder are arranged in the driving cab of the helicopter. The refrigeration air conditioner combines all parts of an air-conditioning system, the compressor and the condenser are arranged on a main reducing platform in a fairing arranged at the front part of an engine compartment, the evaporator is arranged under the floor of the driving cab, a refrigeration operating box is arranged on a control board of the driving cab, and the traditional gas-liquid separator, oil separator and electromagnetic valve are not used in a refrigerating system anymore; and the refrigeration air conditioner for the helicopter is simple in structure, is high / low-temperature resistant, rain-proof, fog-proof and dust-proof and impact resistant, and can meet the using requirements of the helicopter in the aspects of acceleration, vibration, strength, hardness, toughness and ageing performance.

Description

technical field [0001] The invention relates to a refrigeration air conditioner, in particular to an evaporation cycle helicopter refrigeration air conditioner. technical background [0002] Helicopters are widely used because they have many advantages that are difficult or impossible for other aircraft. Because helicopters can take off and land vertically without using a large area airport, they are mainly used for sightseeing, fire rescue, first aid at sea, anti-smuggling and anti-drugs, fire fighting, business transportation, medical assistance, communications, and spraying pesticides and insecticides to eliminate pests and detect resources. field. The fleet of our country's helicopters is growing gradually. [0003] In summer, the highest ground temperature in the hottest part of the country reaches 45°C, and the common high temperature reaches 38°C. In the case of common high temperature on the ground, 1000m in the air, the temperature is above 31.5°C; 3000m in the a...

AI Technical Summary

Problems solved by technology

During the ground test and low-altitude flight of the helicopter, the cabin temperature will be too high and fluctuate to varying degrees.

At present, most helicopter cockpits do not have air-conditioning systems, which can no longer meet the thermal comfort requirements of personnel, which may easily cause fatigue and seriously affect the driver's working ability. Therefore, it is necessary to install an air-conditioning system in the helicopter cockpit to adjust the ambient temperature of the cockpit. and control for improved thermal comfort of personnel

Due to the limitation of the internal space of the helicopter, the air conditioner is equipped separately, which takes up a lot of space inside the helicopter and is not suitable for helicopter use
