Sunken overhead passenger car air conditioner

Abstract

The invention discloses a sunken type top-set air-conditioner of a passenger car. The sunken type top-set air-conditioner is of a split type double-system structure. A cooling system of two condensers, two evaporators, two expansion valves and two liquid supply pipes which all working under a compressor is adopted. The cooling system is designed to be two laterally-symmetric and mutually-independent cooling structures. The two cooling structures are arranged on concave positions, on the two sides below a car ceiling cover, of car body luggage brackets in a sucken type. Highest positions of the cooling structures are not higher than the middle part of the car ceiling cover. The radian of a top cover of each cooling structure is a part transiting from a car ceiling to a side wall of a car body. The structure of the edge of each cooling structure is almost uniform with a large plane of one car body side wall. After installation, the appearance of the cooling structures, the top of the car body of the passenger car, side walls of the car body of the passenger car form a unified whole body. The sunken type top-set air-conditioner of the passenger car is reduced in weight, is provided with a fresh air inlet on the condition that the height of the car body is not increased, and is convenient to maintain, favorable to coordinated development of an air-conditioner structure and a whole shape of the passenger car, and capable of exploring a new conception for the development of air-conditioners of passenger cars.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of passenger car air conditioners, in particular to a sunken overhead passenger car air conditioner applied to large and medium-sized passenger cars. Background technique [0002] Urban transportation, long-distance transportation, and tourist vehicles almost all use large and medium-sized passenger cars. Today, with the development of society and the development of the automobile industry, almost all new large and medium-sized buses are equipped with air-conditioning systems. [0003] The installation methods of the existing large and medium-sized passenger car air-conditioning systems can be divided into various forms such as top-mounted, rear-mounted, bottom-mounted, and built-in types. Considering the installation space of the air conditioner, the convenience of maintenance, and the timely replacement of wearing parts, the layout of the top-mounted air conditioner has become th...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the above problems and provide a sunken overhead passenger car air conditioner, which can integrate the dual advantages of the built-in and overhead air conditioners, move the luggage rack in the car down, and lower the split air conditioner. It is embedded in the space on both sides of the top of the car and makes the highest point of the passenger car air conditioner lower than the skin in the center of the car roof, which not only helps to reduce the height of the top-mounted passenger car air conditioner, but also improves the design freedom of the space in the car; secondly, it can overcome the The defect that the built-in air conditioner placed in the air duct cannot be equipped with a fresh air inlet is conventional. By setting a fresh air door at the front and rear ends of the evaporator assembly, the fresh air from the outside can be introduced into the car body, which can improve the cleanliness of the air inside the car; 3. The split modular design of the sunken air conditioner is small in size and light in weight, which can reduce the overall weight of the passenger car air conditioner
