Air conditioner of passenger vehicle

Abstract

The invention provides a built-in air conditioner of a passenger vehicle. The built-in air conditioner comprises a frame structure (1), and the frame structure (1) is arranged in a trunk of the passenger vehicle; the frame structure (1) comprises an upper-layer structure (2) and a lower-layer structure (3); the upper-layer structure (2) is provided with air outlets and an air return port (6) whichface the interior of a carriage, the air outlets are used for feeding air to the interior of the carriage, and the air return port (6) is used for sucking air in the carriage; the lower-layer structure (3) is provided with cooling ports (7) facing the outside of a vehicle body. According to the air conditioner of the passenger vehicle, the modularized structure is adopted and is compact, the weight of the air conditioner of the passenger vehicle and the weight of the finished vehicle are effectively reduced, and the style development of the finished passenger vehicle is facilitated. The air conditioner is arranged in the tail box of the passenger vehicle, a rear window of the passenger vehicle is not shielded, and lighting of the carriage of the passenger vehicle is not influenced; through the built-in design, the probability of entry of impurities can be lowered, and the fault rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of vehicle air conditioners, and in particular relates to a passenger car air conditioner. Background technique [0002] Air conditioners for passenger cars in the prior art are mainly top-mounted or back-mounted. [0003] The roof-mounted air conditioner is installed on the roof of the bus. The condensate return air and the air outlet are located on the roof. Rainy and snowy days are likely to affect the work of the external fan, and it is easy to enter debris and cause failure. Since the air outlet of the evaporator is located at the top of the interior compartment, the hot air is not easy to blow downwards, and in winter, the upper part of the compartment is hot and the lower part is cold, and the heating effect is poor. Moreover, the overhead air conditioner protrudes from the roof after installation, increases the height of the vehicle, increases the driving wind resistance, and also affects the exteri...

AI Technical Summary

Problems solved by technology

[0003] The roof-mounted air conditioner is installed on the roof of the bus. The condensing return air and the air outlet are located on the roof. Rainy and snowy days are likely to affect the work of the external fan, and it is easy to enter debris and cause failure.

Since the air outlet of the evaporator is located on the top of the interior compartment, the hot air is not easy to blow downwards. In winter, the upper part of the compartment is hot and the lower part is cold, and the heating effect is poor.

Moreover, after the overhead air conditioner is installed, it protrudes from the roof of the vehicle, increases the height of the vehicle, and increases the wind resistance of the vehicle, which also affects the exterior shape of the bus.

The rear-mounted air conditioner unit is relatively large, often occupying the entire rear space of the car, and the rear window of the bus is blocked, affecting lighting and permeability

[0004] Both the top-mounted and rear-mounted air conditioners use a single air duct to supply air, and the heating in winter adopts the upward air supply mode, which has poor heating effect and affects ride comfort
