[0036] Example 1
[0037] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment includes an evaporator 5, which is used to install at the bottom of the tractor cab;
[0038] Condenser 1 is used to install on the side of the tractor engine near the front of the vehicle. The condenser output end of the condenser 1 is connected to the condenser input end of the evaporator 5 through a first high-pressure pipe 7. The first high-pressure pipe 7 is located on the side of the engine.
[0039] The compressor 2 has its condensing output end connected to the condensing input end of the condenser 1 via a second high-pressure pipe 6, and its condensing input end connected to the condensing output end of the evaporator 5 via a low-pressure pipe 9. The second high-pressure pipe 6 and the low-pressure pipe 9 are located on the side of the engine.
[0040] A heater inlet water pipe 10 is provided, one end of which is connected to the water inlet of the evaporator 5, and the other end of which is connected to the water outlet of the engine water circulation system.
[0041] A heater return water rigid pipe 8 is provided, with one end connected to the outlet of the evaporator 5 and the other end connected to the inlet of the engine water circulation system. The heater return water rigid pipe 8 is located above the engine.
[0042] In this embodiment, as needed, a liquid receiver and an expansion valve can be installed on the first high-pressure pipe 7 connecting the condenser 1 and the evaporator 5. The liquid receiver is used to store refrigerant, and the expansion valve is used to control the temperature and flow rate of the refrigerant entering the evaporator 5.
[0043] In an embodiment of this utility model, one end of the heater inlet hose 10 is connected to the inlet of the evaporator 5 via a first heater inlet hose 11, and the other end of the heater inlet hose 10 is connected to the outlet of the engine water circulation system via a second heater inlet hose 13. The two ends of the heater inlet hose 10 are respectively connected to the first heater inlet hose 11 and the second heater inlet hose 13, which facilitates the connection of the heater inlet hose 10 with other devices, and at the same time avoids the impact on the other devices when one of the connected devices moves.
[0044] Furthermore, both ends of the heating water inlet rigid pipe 10 are fixedly connected to the first heating water inlet hose 11 and the second heating water inlet hose 13 by fixing pipe clamps, respectively. The setting of fixing pipe clamps can further ensure the stability of the connection between the heating water inlet rigid pipe 10 and the first heating water inlet hose 11 and the second heating water inlet hose 13.
[0045] One end of the heater return water rigid pipe 8 is connected to the outlet of the evaporator 5 through the first heater return water hose 12, and the other end of the heater return water rigid pipe 8 is connected to the inlet of the engine water circulation system through the second heater return water hose 14. The two ends of the heater return water rigid pipe 8 are connected to the first heater return water hose 12 and the second heater return water hose 14 respectively, which facilitates the connection of the heater return water rigid pipe 8 with other devices, and at the same time avoids that if one of the connected devices moves, it will affect the other devices.
[0046] Furthermore, both ends of the heating return water rigid pipe 8 are fixedly connected to the first heating return water hose 12 and the second heating return water hose 14 by fixing pipe clamps, respectively. The setting of fixing pipe clamps can further ensure the stability of the connection between the heating return water rigid pipe 8 and the first heating return water hose 12 and the second heating return water hose 14.
[0047] In this embodiment, a heat exchange assembly is installed inside the evaporator 5. Through the arrangement of the warm air inlet pipe 10 and the warm air return pipe 8, when cooling of the water in the engine water circulation system is required, the warm air inlet pipe 10 introduces water from the engine water circulation system into the evaporator 5, where heat exchange occurs, lowering the water temperature. Then, the water is returned to the engine water circulation system through the warm air return pipe 8, improving the engine's cooling effect. When heating is required, the warm air return pipe 8 is positioned above the engine, close to the heat source, absorbing heat from the heat source and improving the heating effect to a certain extent.
[0048] In this embodiment, in order to facilitate the opening and closing of the pipes as needed, solenoid valves are provided on both the warm air inlet hard pipe 10 and the warm air return hard pipe 8.
[0049] In this embodiment, the heater inlet hard pipe 10 and the heater return hard pipe 8 are fixed to the vehicle frame by fasteners. The fasteners are common fasteners in the prior art to ensure the stability of the fixing of the heater inlet hard pipe 10 and the heater return hard pipe 8.
[0050] In this embodiment, the first high-pressure pipe 7, the second high-pressure pipe 6, and the low-pressure pipe 9 are located on the left side of the tractor (the left side refers to the left side in the forward direction) and on the left side of the engine, which facilitates maintenance. The heater inlet pipe 10 and the heater return pipe 8 are far away from high-temperature devices, ensuring the cooling effect of the air conditioner.
[0051] It also includes an air conditioning duct 4 inside the driver's cab and an air conditioning duct 3 outside the driver's cab. The air conditioning duct 4 inside the driver's cab is installed inside the driver's cab and is connected to the air outlet of the evaporator 5. The air conditioning duct 3 outside the driver's cab is installed outside the driver's cab and is connected to the air inlet of the evaporator 5.
[0052] In an embodiment of this utility model, a radiator (not shown in the drawings) is also included. The radiator is located on the side of the engine near the front of the vehicle, and the condenser 1 is located on the side of the radiator near the front of the vehicle. The radiator can improve the heat dissipation effect of the condenser 1. A hinge part is provided on one side of the condenser 1 for hinged with the front of the tractor, which facilitates cleaning of the condenser 1 and the radiator.
[0053] In this embodiment, by placing the first high-pressure pipe 7, the second high-pressure pipe 6, and the low-pressure pipe 9 on the side of the engine, the first high-pressure pipe 7, the second high-pressure pipe 6, and the low-pressure pipe 9 are kept away from the heat source above the engine, thereby reducing the impact on the refrigeration pipes and ensuring the cooling effect of the air conditioning system. At the same time, the heater return water hard pipe 8 is placed above the engine, so that the heater return water hard pipe 8 is close to the heat source, which can improve the heating effect when heating.

[0055] This embodiment discloses a tractor, including the aforementioned arrangement of the tractor air conditioning system. By placing the first high-pressure pipe 7, the second high-pressure pipe 6, and the low-pressure pipe 9 on the side of the engine, the first high-pressure pipe 7, the second high-pressure pipe 6, and the low-pressure pipe 9 are prevented from being close to the heat source above the engine, thereby reducing the impact on the refrigeration pipes and ensuring the cooling effect of the air conditioning system. At the same time, the heater return water hard pipe 8 is placed above the engine, so that the heater return water hard pipe 8 is close to the heat source, which can improve the heating effect during heating.
