[0029] Example 1: A split air conditioner for a caravan or campervan, see Figures 1-11As shown, it includes an air conditioner indoor unit 1, a control panel 103, an air guide cover 2, an evaporator 3, a first air guide pipe 4, a first fan 5, an air conditioner outdoor unit, an angle iron 101, a threaded connector 401, a threaded connector sleeve 402, a second air guide pipe 6, a fourth air guide pipe 14, an electric compressor 7, a third air guide pipe 8, a mounting shell 9, a condenser 10, a second fan 12 and an expansion valve 13. The control panel 103 is installed at the lower part of the air conditioner indoor unit 1. A plurality of air guide covers 2 are rotatably provided on the air conditioner indoor unit 1. A rubber block 25 is fixed to the air guide cover 2. By toggling the rubber block 25, it is convenient to adjust the angle of the air guide cover 2. The evaporator 3 is installed in the air conditioner indoor unit 1 by bolt connection. The air conditioner indoor unit 1 A first air guide pipe 4 is installed on the upper part, and the first air guide pipe 4 is "S"-shaped and passes through the evaporator 3, and both ends of the first air guide pipe 4 pass through the right side of the air conditioner indoor unit 1. Six first fans 5 are installed on the rear side of the air conditioner indoor unit 1 by bolt connection. A dustproof net 24 is installed on the side of the fan 5 away from the evaporator 3. The dustproof net 24 prevents foreign matter from entering the first fan 5. An angle iron 101 is installed on both sides of the air conditioner indoor unit 1 by bolt connection. There are multiple connection holes 102 on the angle iron 101. Both ends of the first air guide pipe 4 are fixed with a threaded connector 401. A threaded connection sleeve 402 is threadedly provided on the threaded connection sleeve 402. A rubber ring 403 is provided in the threaded connection sleeve 402. The rubber ring 40 3 is in contact with the threaded connector 401 on one side away from the threaded connection sleeve 402. The second guide pipe 6 and the fourth guide pipe 14 are rotatably provided on the two threaded connection sleeves 402. The second guide pipe 6 is installed with an electric compressor 7 away from the lower end. The second guide pipe 6 is connected to the input end of the electric compressor 7. The fourth guide pipe 14 is installed with an expansion valve 13 on one end away from the first guide pipe 4. A condenser 10 is installed in the installation shell 9. The third guide pipe 8 is "S" shaped and passes through the condenser 10. A second fan 12 is installed on the front side of the installation shell 9. The third guide pipe 8 passes through the rear side of the installation shell 9. The two ends of the third guide pipe 8 are connected to the second guide pipe 6 and the fourth guide pipe 14 respectively. The first fan 5 and the electric compressor 7 are installed on the other side. The signal input ends of the compressor 7 and the second fan 12 are electrically connected to the model output ends of the control panel 103. The output end and the input end of the expansion valve 13 are both provided with a slide groove 22. The third guide tube 8 and the fourth guide tube 14 are fixedly connected to one end of the expansion valve 13. The fixed joint 23 is circumferentially provided with a protrusion. The fixed joint 23 is engaged with the adjacent slide groove 22. When connecting the third guide tube 8 and the fourth guide tube 14 to the expansion valve 13, the fixed joint 23 is inserted into the slide groove 22, and the third guide tube 8 and the fourth guide tube 14 are rotated so that the protrusions on the circumference of the fixed joint 23 are inserted into the slide groove 22, thereby facilitating the quick connection of the third guide tube 8 and the fourth guide tube 14 to the expansion valve 13.
[0030] When a split-type air conditioner is to be installed, the mounting housing 9 and the electric compressor 7 are mounted on the outside of the compartment of the RV camper by means of bolts. The bolts are passed through the connection holes 102 on the angle iron 101 to mount the air conditioner indoor unit 1 on the inside of the compartment of the camper. The threaded connection sleeve 402 on the second guide pipe 6 is sleeved on the threaded connection head 401 at the output end of the first guide pipe 4. The threaded connection sleeve 402 on the fourth guide pipe 14 is sleeved on the threaded connection head 401 at the input end of the first guide pipe 4.

The output end and input end of the first conduit 4 are connected, and the second conduit 6 and the fourth conduit 14 are passed through the pipe hole of the RV camper. Then, the input end of the electric compressor 7 is connected to the output end of the first conduit 4, and the other end of the fourth conduit 14 is connected to the output end of the expansion valve 13. Subsequently, the output end of the electric compressor 7 is connected to the third conduit 8, and the other end of the third conduit 8 is connected to the input end of the expansion valve 13. Thus, there is no need to open a shell mounting hole on the vehicle body, and the air conditioner indoor unit 1, the electric compressor 7 and the condenser 10 are installed separately inside and outside the vehicle compartment, reducing the impact on the vehicle compartment during air conditioning operation. The refrigerant is then added to the electric compressor 7, and the first fan 5, the electric compressor 7, and the second fan 12 are connected to the power supply of the RV camper. The first fan 5, the electric compressor 7, and the second fan 12 are then started through the control panel 103. The electric compressor 7 compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gas and sends it into the third guide pipe 8. The second fan 12 drives the air flow. The heat of the refrigerant in the third guide pipe 8 is dissipated to the air outside the vehicle through the condenser 10 to improve the cooling efficiency of the air conditioner, so that the refrigerant is cooled and liquefied into a high-pressure liquid. The refrigerant is then It enters the expansion valve 13 through the third guide pipe 8. At this time, the pressure of the refrigerant drops sharply and the temperature also drops accordingly, turning into a low-temperature, low-pressure liquid. The low-temperature, low-pressure liquid refrigerant enters the first guide pipe 4 through the fourth guide pipe 14, and then enters the evaporator 3 through the first guide pipe 4, where it absorbs heat from the indoor air, thereby cooling the air around the evaporator 3. The refrigerant changes from liquid to gas. At this time, the first fan 5 runs, blowing the cooled air back to the compartment of the RV camper to achieve a cooling effect. The gaseous refrigerant is again sucked into the electric compressor 7, starting a new cycle.
[0031] Example 2: Based on Example 1, refer to Figure 1 and Figure 6 As shown, it also includes a protective cover 11, a slide rail 15 and a slider 16. The slide rails 15 are installed on the upper and lower sides of the mounting shell 9. The sliders 16 are slidably provided on the two slide rails 15. A protective cover 11 is installed between the two sliders 16. The protective cover 11 covers the second fan 12. The protective cover 11 is provided with multiple buckle grooves 17 on the side away from the front side, and the buckle grooves 17 are used to facilitate the removal and placement of the protective cover 11.
[0032] See Figure 1 、 Figure 6 and Figure 9 As shown, it also includes a snap-on shell 18, a fixed shell 19, a clamping block 20 and a handwheel 21. The fixed shell 19 is fixedly connected to the left side of the mounting shell 9 by welding. A handwheel 21 is rotatably provided on the fixed shell 19. One end of the handwheel 21 located in the fixed shell 19 is fixedly connected to the clamping block 20. The right side of the protective cover 11 is fixedly connected to the snap-on shell 18, and the clamping block 20 is rotatably clamped to the snap-on shell 18.
[0033] When installing the protective cover 11, align the slider 16 with the slide rail 15, and then slide the protective cover 11 inward until the snap-on shell 18 is aligned with the fixed shell 19. At this time, the protective cover 11 covers the second fan 12 to prevent foreign objects from being caught in the second fan 12 when in use. Then turn the hand wheel 21, and the hand wheel 21 drives the clamping block 20 to rotate, so that the clamping block 20 is clamped with the snap-on shell 18, thereby achieving quick installation of the protective cover 11, facilitating the installation and removal of the protective cover 11, and facilitating the maintenance of the condenser 10 and the second fan 12.
