Technical Field

the invention relates to the technical field of automobile air conditioners, in particular to a top-mounted automobile air conditioning system.

Background

The automobile air conditioner is an air conditioning device installed on an automobile, and can cool, heat, ventilate and purify air in a carriage, provide comfortable riding environment for passengers, reduce fatigue strength of drivers, improve driving safety and determine whether the functions of the automobile are complete or not.

Generally comprises a refrigerating device, a heating device and a ventilation device, the combined device makes full use of the limited space in the automobile, has simple structure and convenient operation, and is an internationally popular modern automobile air conditioning system.

As the traveling speed increases, the specific gravity of the fuel consumption of the air conditioning system gradually decreases. At present, the attention on energy conservation and emission reduction is paid, a new way is found to reduce the energy consumption of the automobile air conditioner, the comfort, the reliability and the safety of the automobile air conditioner are ensured, and the method has great significance for the continuous development of the automobile industry and the energy conservation and emission reduction.

The existing automobile air conditioning system is generally installed in an engine hood at the front part of an automobile, is suitable for family small cars or SUVs, and is not suitable for large trucks and buses.

Disclosure of Invention

In order to solve the above technical problems, the present invention discloses a top mounted type vehicle air conditioning system, which employs an evaporator unit and a blower unit arranged on the top of a vehicle, wherein an engine drives a compressor to work through a transmission belt, and both an evaporator blower and a condenser fan are directly driven by an electric motor. Because the non-independent driving is adopted and no auxiliary engine is arranged, the maintenance cost is greatly reduced, the noise and the vibration are small, and the pressure of the rear wheel is reduced.

In order to achieve the purpose, the invention adopts the following specific technical scheme:

An overhead automobile air conditioning system comprises a liquid storage dryer, an evaporator, a blower assembly, a compressor and a condenser.

The invention further improves the structure that the liquid storage dryer is arranged at the inner edge of the engine cover at the front part of the vehicle, the evaporator and the blower assembly are arranged at the top part of the vehicle, the compressor is arranged at the front side in the engine cover, and the condenser is arranged at the lower side of the front windshield. The evaporator unit and the blower unit are arranged on the top of the automobile, and the engine drives the compressor to work through a transmission belt, so that the pressure of a rear wheel is reduced.

In a further refinement of the present invention, an evaporator and blower assembly includes an evaporator and a blower.

The invention further improves that the evaporator is divided into a left evaporator part and a right evaporator part, each part is provided with an expansion valve and is provided with 4 electric blowers for forced ventilation, and the blowers are arranged on the sides of the left evaporator part and the right evaporator part. Both the evaporator air mover and the condenser fan are driven directly by the motor. Because the non-independent driving is adopted and no auxiliary engine is arranged, the maintenance cost is greatly reduced, and the noise and the vibration are small.

The invention has the beneficial effects that: compared with the existing automobile air conditioning system, the automobile air conditioning system adopts the evaporator unit and the blower unit which are arranged on the top of an automobile, the engine drives the compressor to work through a transmission belt, and both the evaporator blower and the condenser fan are directly driven by the motor. Because the non-independent driving is adopted and no auxiliary engine is arranged, the maintenance cost is greatly reduced, the noise and the vibration are small, and the pressure of the rear wheel is reduced.
