Dry and wet air layered flowing air conditioner ventilation system

Abstract

The invention relates to a dry and wet air layered flowing air conditioner ventilation system, and belongs to the field of automobile air conditioners, the system comprises an air conditioning box, and an impeller, a filter, an evaporator and a warm air core body which are sequentially arranged in the air conditioning box along the air flowing direction, an inner partition plate penetrating through the impeller, the filter, the evaporator and the warm air core is arranged in the air conditioner box and used for dividing the inner space of the air conditioner box into a first air duct and a second air duct. The air inlet shell is provided with an outside-vehicle fresh air duct, a defrosting air duct, a face blowing air duct, a foot blowing air duct and an inside-vehicle return air duct. One end of the first air duct communicates with the outside-vehicle fresh air duct, and the other end of the first air duct communicates with the defrosting air duct and the face blowing air duct; one end of the second air duct is communicated with the in-vehicle air return duct, and the other end is communicated with the foot blowing air duct. Dry and wet air partition can be achieved, the axial size of the air conditioning system is reduced, and miniaturization of the air conditioning system is achieved.

Description

technical field [0001] The invention belongs to the field of automobile air conditioners, and relates to an air conditioner ventilation system with dry and wet air layered flow. Background technique [0002] At present, new energy vehicles and smart vehicles need to add various new functions and implement various intelligent control schemes, requiring more space for electronic control equipment and electronic intelligent equipment, so the design of the air conditioning box is required to be more compact. At the same time, since new energy pure electric vehicles do not have waste heat recovery from the engine, they will consume a lot of high-grade electric energy for heating when used in winter. In order to save electric energy consumption and increase cruising mileage, the external circulation fresh air mode (mainly dry air with low temperature) cannot Fully open for a long time to avoid a large amount of cooling load. However, the air humidity in the internal circulation re...
