[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0017] See also Figure 1-4 The present application provides a technical solution: a protective cover for a bus air conditioner, comprising an evaporative emission device assembly 1 and a control unit assembly 2, wherein the evaporative emission device assembly 1 and the control unit assembly 2 are arranged adjacent to each other, and a first air outlet 5 and a second air outlet 7 are arranged on both sides of the evaporative emission device assembly 1.

[0018] The evaporative emission device assembly 1 is responsible for handling the condensed water generated during the operation of the air conditioner. When the air is cooled in the evaporator, the moisture in the air condenses into water droplets. The evaporative emission device assembly 1 collects this moisture and guides it out of the vehicle through a specific pipe to avoid equipment corrosion, mildew or electrical short circuit caused by water accumulation, thereby protecting the air conditioning system and maintaining the sanitary environment in the vehicle.

[0019] The control unit assembly 2 integrates a variety of sensors, controllers and actuators, and can automatically adjust the air-conditioning operating mode, air volume, temperature and other parameters according to external environmental conditions (such as the temperature inside and outside the vehicle) and user settings. This ensures the intelligent operation of the air-conditioning system, improves the energy efficiency ratio, and provides passengers with a comfortable riding experience.

[0020] The first air outlet 5 and the second air outlet 7 are channels for the air conditioning system to deliver processed (heated or cooled) air into the vehicle compartment; the first air outlet 5 and the second air outlet 7 are usually distributed on both sides of the evaporative emission device assembly 1, which helps to achieve uniform distribution of airflow in the vehicle compartment, so that passengers can feel the appropriate temperature no matter which area they sit in; it helps to quickly adjust the temperature in the vehicle compartment and reduce energy consumption.

[0021] The raised end in the middle of the evaporative emission device assembly 1 is the evaporator fan 6 , air return passages 13 are arranged on both sides of the evaporator fan 6 , and a heat dissipation window 11 is arranged on one side of the evaporator fan 6 .

[0022] The evaporator fan 6 is located inside the evaporative emission device assembly 1, accelerating the air flow through the evaporator surface. The evaporator is a key part of the refrigeration cycle in the air conditioning system, responsible for absorbing the heat of the air in the cabin with low-temperature and low-pressure refrigerant and condensing the air. The operation of the evaporator fan 6 ensures the heat exchange efficiency, thereby effectively reducing the air temperature. The raised design of the evaporator fan 6 is intended to optimize the airflow direction or improve the ventilation efficiency in a limited space.

[0023] The air return channel 13 is designed to improve airflow dynamics and promote air circulation inside the cabin. When fresh cold air is cooled by the evaporator and sent into the cabin through the air outlet, the air return channel 13 helps guide the hot air in the cabin back to the vicinity of the evaporator, forming a more effective heat exchange cycle. This accelerates the temperature uniformity in the cabin, reduces energy consumption, and improves the comfort of passengers.

[0024] The heat dissipation window 11 is provided to discharge the heat generated when the evaporator fan 6 is in operation, as well as the hot air recovered from the vehicle compartment. The heat dissipation window 11 can be directly discharged outside the vehicle to avoid accumulation inside the air conditioning system, which helps to maintain the evaporator and its surrounding electronic components within a suitable operating temperature range, thereby ensuring the long-term stability and efficiency of the air conditioning system.

[0025] Furthermore, a control harness hole 4 and a high-voltage power cable hole 9 are respectively provided at both ends of the first air outlet 5 and the second air outlet 7 .

[0026] The first air outlet 5 and the second air outlet 7 are not only used to deliver processed air into the vehicle compartment to ensure the comfort of the environment in the vehicle compartment, but also a control harness hole 4 and a high-voltage power cable hole 9 are respectively provided at both ends thereof.

[0027] The control harness hole 4 is used to pass the control harness of the air conditioning system. The harness is responsible for transmitting control signals, such as instructions from the cab or the automatic temperature control system, to the air conditioning control unit assembly 2. The control signals may include temperature settings, fan speeds, and switching commands for operating modes (such as cooling, heating, dehumidification, etc.). The dedicated harness hole can ensure that the harness is arranged in an orderly and safe manner to avoid damage during air conditioning operation or vehicle vibration, and is also convenient for maintenance and replacement.

[0028] The high-voltage power cable hole 9 is used to pass the high-voltage cable for powering the air-conditioning system. For high-energy consumption components such as the electric compressor in the electric bus, high-voltage power supply support is required to prevent the risk of electric shock and electromagnetic interference. The stability and safety of the power supply are ensured, and the management and maintenance of the cables are simplified.

[0029] Furthermore, a bypass inlet pipe 8 and a bypass outlet pipe 12 are provided at the middle position of the second air outlet 7 .

[0030] The bypass inlet pipe 8 is a part of the bypass control system. The function of the bypass inlet pipe 8 is to draw air from the inside of the vehicle or the outside environment. Under specific working conditions, the efficiency of the air conditioning system is adjusted or adapted to different operating requirements. When the temperature difference between the inside and outside of the vehicle is not large, the bypass can introduce a proper amount of external air to reduce the load of the compressor, save energy consumption, and maintain appropriate air circulation in the vehicle.

[0031] The bypass outlet pipe 12 corresponds to the bypass inlet pipe 8 and is the outlet for bypass air. After necessary conditioning (such as mixing, filtering, etc.), the introduced air is sent back to the compartment or directly discharged to the outside through this pipe, which can flexibly control the air pressure balance inside the compartment, optimize air circulation, avoid excessive negative pressure or positive pressure, and improve passenger comfort.

[0032] Furthermore, a sealing component 10 is provided on the inner side of the evaporative emission device assembly 1 .

[0033] The sealing assembly 10 ensures the sealing inside the evaporative emission device to prevent the refrigerant or other working media (such as condensed water) from leaking into the external environment. Leakage will not only cause the efficiency of the air-conditioning system to decrease, but may also cause damage to the electronic components inside the vehicle and even affect the safety of passengers.

[0034] Furthermore, the control unit assembly 2 is provided with a through hole 3 for pre-embedded top plate bolts.

[0035] When in use: connect the control harness 4 to the control unit assembly 2, ensure that all control signal lines are correctly connected, including temperature sensors, wind speed control and other signals, use the high-voltage power cable hole 9 to safely pass the high-voltage cable to power components such as the electric compressor, pay attention to electrical safety, and avoid the risk of short circuit and electric shock.

[0036] The bypass inlet pipe 8 and the bypass outlet pipe 12 are adjusted according to the actual temperature and the environment in the vehicle compartment, and the control system determines whether to enable the bypass mode to save energy and optimize airflow.

[0037] According to passenger demand and external ambient temperature, the air conditioner's operating mode, temperature and air volume are set through the cab or automatic temperature control system; the control unit assembly 2 will automatically adjust the evaporator fan 6 speed, hot and cold air ratio, etc. to ensure that the temperature in the car is appropriate.

[0038] Regularly check the sealing component 10 and drainage conditions of the evaporative emission device assembly 1 to ensure smooth discharge of condensed water, avoid corrosion or mildew caused by accumulated water, and maintain hygiene in the vehicle compartment.

[0039] Clean the evaporator fan 6 and the air return duct 13 regularly to prevent dust accumulation from affecting the heat exchange efficiency and air circulation, and ensure that the heat dissipation window 11 is unobstructed to avoid heat accumulation that affects the life of the air conditioning components.

[0040] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
