Modularly designed overhead air conditioning unit for passenger car

Abstract

The invention discloses a modularly designed overhead air conditioning unit for a passenger car, and the modularly designed overhead air conditioning unit is suitable for an air conditioning system ofthe passenger car, and is used for enhancing the matching and mounting flexibility of the air conditioning system unit and the whole passenger car and enabling the overhead air conditioning unit forthe passenger car to have certain expansibility. The modularly designed overhead air conditioning unit comprises at least one heat pump module, at least one outdoor heat exchange module, at least oneindoor heat exchange module and an electrical module, and the specific number and the specific arrangement mode of the heat pump modules, the outdoor heat exchange modules and the indoor heat exchangemodules are limited according to requirements of the passenger car air conditioning system.

Description

technical field [0001] The invention belongs to the field of passenger car air conditioners, and in particular relates to a modular design of a passenger car roof-mounted air conditioner unit. Background technique [0002] With the development of society and the continuous improvement of people's living standards, new energy vehicles, as an environmentally friendly vehicle type, are taking an increasing share in the market. However, since new energy vehicles have the characteristics of small energy storage, the response method adopted by the OEM is to add more batteries or fuel packs. For the passenger car industry, due to space constraints, it is common to install a large number of energy storage components on the roof. This results in less and less space left for overhead air conditioners. How to effectively use these spaces is a problem faced by all passenger car air conditioners. [0003] Vehicle air conditioners, especially passenger car air conditioners, often adopt ...

AI Technical Summary

Problems solved by technology

[0005] The existing roof-mounted air-conditioning unit structure for passenger cars can meet the customer's demand for air-conditioning products to a certain extent, but it still has obvious defects: 1. Under a certain overhead unit structure, the position of the air outlet and the return air outlet are relatively The air conditioner itself is determined, which leads to the adjustment of the overall structure of the air conditioner after the corresponding size of the vehicle is adjusted. The flexibility is small, and the same air conditioner design cannot meet different needs; 2. After the size of the air conditioner package is finalized, the air conditioner inside The size of the evaporator and condenser will not be adjusted accordingly, so the performance of the air conditioning unit will have a maximum value and lack of scalability; 3. The components of the air conditioning system and different structural parts have different requirements for waterproofing and heat preservation. However, due to the influence of the integrated design, it cannot be treated differently, and the cost optimization cannot be achieved
