Problems solved by technology

[0009] Since absorption air conditioning units require a heat supply, typically from the vehicle engine, for desorption, desorption cannot be performed effectively until the engine is warm

Embodiment Construction

[0035] A preferred but not exclusive type of absorption air conditioning unit for use with the present invention uses a dual fluid circuit, one carrying a refrigerant fluid, such as water; the other carrying an absorbent fluid, such as a lithium bromide (LiBr) salt solution.

[0036] figure 1 Briefly represent the components and working principle of the absorption air-conditioning device. It comprises: elements in which desorption takes place, hereinafter referred to as "desorber" 100 , condenser 200 , evaporator 300 and absorber 400 .

[0037] The desorber 100 and absorber 400 are filled with a mixture of at least two miscible substances formed from a refrigerant fluid and an absorbent fluid. This mixture is mixed in the absorber 400 where the absorbent fluid absorbs the refrigerant fluid in the vapor phase.

[0038] The evaporation pressures of the refrigerant fluid and the absorbent fluid are quite different so that when the mixture is heated in the desorber 100, the more...

Abstract

The invention relates to an air-conditioning device, particularly for a motor vehicle, comprising a tank (1) for collecting a liquid, said tank being formed by two compartments that are intercommunicated by means of a first passage (18) located in the lower portion of the tank. The first compartment, known as the main compartment (15), includes a liquid inlet (11) and a lower liquid outlet (12), while the second compartment, known as the auxiliary compartment (16), includes delivery means for delivering at least part of the liquid from the auxiliary compartment into the main compartment (15) through the above-mentioned first passage (18).

Description

technical field [0001] The present invention relates to an improved air conditioning unit. [0002] It also relates to a motor vehicle equipped with such an improved air conditioning unit. Background technique [0003] Among the existing air conditioning installations, known absorption air conditioning installations rely on an absorbent fluid to absorb a gaseous refrigerant fluid. Unlike traditional mechanical compression air conditioning units, this absorption air conditioning unit has few moving parts because there is no mechanical compression, which limits noise and vibration, simplifies maintenance, and improves the service life and reliability of the unit. [0004] Attempts have been made to improve the performance of absorption air conditioning units so that they can be installed in motor vehicles in a simple and reliable manner. Therefore, the FR2900723 document exemplifies such an air-conditioning unit comprising an evaporator / absorber assembly consisting of perfor...
