Specific embodiment
As shown in attached drawing 1-5, the present invention includes compressor 1, clutch 2, condenser 3, evaporator 4, liquid storage device 5 and swollen
Swollen valve 6；Clutch 2 is mounted on the main shaft of compressor 1, and belt pulley, aircraft engine and clutch 2 are installed in 2 front end of clutch
Belt pulley is connected by driving belt, and compressor 1 is mounted on engine-side by bracket；Condenser 3 is mounted on fuselage afterbody
On installation gusset 13 between seven frames and eight frames；Liquid storage device 5 and expansion valve 6 are mounted on condenser 3；Condenser 3 is located at body
Hot air outlet 12 is installed in tail portion on the outside of condenser 3.
Evaporator 4 of the present invention is mounted on the stringer between five frames and six frames and reinforcer, is located at six frame front upper parts, in institute
The cooling air pipeline 10 for stating installation 1 or more on evaporator 4, is positioned at pilot in 10 end of cooling air pipeline
The cooling air air outlet 11 on head.The refrigerant outlet of evaporator 4 and the refrigerant inlet of compressor 1 pass through the first pipeline 7
Connection；It is connected between the refrigerant outlet of compressor 1 and the refrigerant inlet of condenser 3 by the second pipeline 8；Compressor 1 with
It is connected between evaporator 4 by third pipeline 9.Evaporator 4 is located at top after cockpit, installed on the evaporator 41 with
On cooling air pipeline 10, be positioned at the cooling air air outlet on pilot head in 10 end of cooling air pipeline
11.The installation control box 14 in cockpit, is arranged function knob switch 15 and wind speed rotary switch 16 on control box 14；It is described
Control box 14 is connect by conducting wire with clutch 2, condenser 3 and evaporator 4.
Present system completes evaporation endothermic process in evaporator, completes condensation exothermic process, compression within the condenser
Machine 1 sucks the refrigerant gas of the low-temp low-pressure in 4 exit of evaporator by the first pipeline 7, it is compressed into high temperature and pressure
Compressor 1 is discharged in gas, and the superheated refrigerant gas of high temperature and pressure enters condenser 3 by the second pipeline 8, due to pressure and temperature
The reduction of degree, refrigerant gas is condensed into fluid storage in liquid storage device 5, and a large amount of heat is discharged, and hot gas is gone out by hot wind
Air port 12 is discharged outside body, and the higher refrigerant liquid of temperature and pressure is become larger by volume after expansion valve 6, and pressure and temperature is anxious
Expansion valve 6 is discharged with mist in play decline, and atomized refrigerant liquid enters evaporator 4 by third pipeline 9, because of refrigerant at this time
Boiling point is far below temperature in evaporator 4, therefore refrigerant liquid flashes to gas, and cold air passes through cooling air pipeline 10 and cooling sky
Gas air outlet 11 blows to pilot into cockpit, largely absorb in evaporation process around heat, then low-temp low-pressure
Refrigerant vapour enters compressor 1 again.Progress during such working principle in cycles.
Present system is controlled by being set to the control box 14 in cockpit on instrument board at pilot, is controlled
Function knob switch 15, wind speed rotary switch 16 on box processed can carry out the ON/OFF of refrigeration system, refrigeration/ventilation mode is cut
It changes, the operation that temperature is adjusted and high/low two grades of wind speed are adjusted.Pilot can be adjusted according to the needs 15 He of function knob switch
The selection of wind speed rotary switch 16 ventilation or refrigeration mode, under ventilation mode, only 4 blower of evaporator works；It is first under refrigeration mode
First start evaporator 4,3 blower of condenser, it is high/low can to carry out air quantity under ventilation or refrigeration mode for rear delay start clutch
It adjusts.
The refrigerated air-conditioning system of Small General Aircraft of the present invention, which has, passes through transmission using piston aviation engine main shaft
The compressor 1 that belt drives, for controlling the clutch 2 of the work of compressor 1, into cockpit for the evaporator of cold air 4, being used for will
The condenser 3 of interior of aircraft heat discharge out of my cabin, the control box 14 of control refrigerated air-conditioning system work.Refrigeration provided by the invention
Air-conditioning system, the mechanical kinetic energy using aircraft engine are the power resources of compressor, 4 power resources of condenser 3 and evaporator
The generator powered on aircraft uses nontoxic R-134a refrigerant as heat exchange medium, has structure and simply may be used
It leans on, good environmental adaptability, consumption electric energy is small, safeguards easy to use, good refrigeration effect, there is ventilation, refrigeration, air quantity adjusting, temperature
The functions such as protection, provide a comfortable temperature field for occupant in cabin, meet the needs of Small General Aircraft.
Finally, it is stated that the foregoing is merely illustrative of the preferred embodiments of the present invention, it is not intended to limit the invention, it is all
Any modification, equivalent replacement or improvement etc., should be included in guarantor of the invention made by within the spirit and principles in the present invention
