Description

HVAC system and vehicle

Technical Field

The utility model belongs to the technical field of automobiles, and particularly relates to an HVAC system and a vehicle.

Background

The existing automatic air conditioning system of the automobile is provided with external circulation and internal circulation air intake, but the independent external circulation and the independent internal circulation have certain defects. The disadvantages are as follows:

If the external circulation is high in internal consumption, the pollution can be inhaled in heavy pollution areas; while the internal circulation has less fresh air intake and is easy to fog.

An HVAC module for a vehicle includes a housing as disclosed in patent document publication No. CN111819094 a. The shaft end is connected to the shaft for connection to a complementary actuator for adjusting the rotational position of the shaft and thereby the position of the airflow control door in the housing. The shaft end defines an actuation axis. An externally threaded boss coaxial with the shaft end is defined on the outer surface of the housing. A rotation stop post projects from the housing to engage a catch defined by the complementary actuator. The housing retains the complementary actuator by threaded engagement with the externally threaded boss and by engagement between the rotation stop post and the catch to selectively prevent rotation of the housing of the complementary actuator about the actuation axis. The complementary actuators are interchangeably an electric rotary actuator and a manually operable rotary actuator. The technical solution disclosed in this patent document also fails to solve the above-described technical problems.

Specifically, as shown in fig. 1 to 3, the air inlet box 2 is connected with the distribution box 3 through a volute, the air inlet box 2 comprises a housing 205, an internal and external circulation air door assembly 203, a filter element 204, a volute 206, an impeller 208, a motor 209, a motor support 210 and a motor end cover 211, the external circulation air inlet 201 and the internal circulation air inlet 202 are arranged at the upper end of the housing 205, and the lower end of the housing 205 is provided with an air outlet. Impeller 208, motor 209, motor mount 210, motor end cap 211 comprise a blower assembly.

As shown in fig. 4, the internal and external circulation air door assembly 203 is driven by a micro motor, so that the air door can be stopped at any angle, and the full internal circulation, the full external circulation and the internal/external circulation air inlet with any proportion can be realized.

The layering partition plate 207 is designed inside the volute and the distribution box 3, the Z-position setting of the layering partition plate 207 is aligned with half of the height of the blower impeller, and the air inlet box 2, the volute and the distribution box 3 are divided into an upper layer and a lower layer through connection, so that layering of the internal space of the HVAC assembly is achieved. The shell 205 is similar to a trumpet-shaped tulip structure, and an air inlet of the shell is matched with the filter element to receive air filtered by the filter element; the air outlet of the housing 205 extends to a position aligned half the height of the blower wheel 208, the air outlet being just flush with the height of the layered separator 207. The edge of the air outlet is typically provided with a 2-4mm gap from the blower wheel 208 to prevent the wheel from rotating and rubbing against the housing 205.

As indicated by arrows in fig. 3, the air outside the vehicle and the air inside the vehicle are respectively introduced from the external circulation air inlet 201 and the internal circulation air inlet 202 through the air blower, filtered by the filter element and then introduced into the shell 205 for diversion and distribution, the internal circulation air is respectively introduced into the lower layers of the air inlet box 2, the volute and the distribution box 3 through the shell 205 structure, and the external circulation air is respectively introduced into the upper layers of the air inlet box 2, the volute and the distribution box 3 through the shell 205 structure.

As shown in fig. 6, after the flow is guided and distributed through the housing 205, the layered separator 207 is layered, and the gas layering simulation effect is obvious.

As shown in fig. 5, the distributor box 3 is mainly composed of an evaporator 301, a heater 302, a mode damper assembly, and a mixing damper assembly. The evaporator 301 is used as a heat exchanger and can exchange heat with the passing external fresh air and the passing internal air so as to achieve the purpose of refrigerating the passing external fresh air and the passing internal air; the heater 302 can be used as a heat exchanger to exchange heat with the passing external fresh air and the passing internal air so as to achieve the purpose of heating the passing external fresh air and the passing internal air; the mixing air door assembly is driven by a micro motor, and the temperature of gas required by different opening degrees of the mixing air door assembly is regulated, so that the air mixing effect is achieved; the mode air door assembly is driven by the micro motor, and the mode air door assembly is used for adjusting gas to blow into the vehicle through different air outlets of blowing face, foot blowing and defrosting.

As shown in fig. 5, through the flow guiding and layering functions of the tulip structure and the layering partition plate 207, the internal air is blown out from the lower layer through the foot blowing air duct, and the air conditioner can be used for heating the whole car; the humidity of the outside air is lower, and the outside air is blown out from the upper layer through the defrosting air duct and is blown to the glass to prevent fog. The purposes of improving comfort and saving energy are achieved by introducing air in/out of the vehicle in a layered manner.

As shown in fig. 5, through the flow guiding of the tulip structure and the penetrating layering action of the layering partition plate 207, the outside fresh air enters the upper layer of the distribution box 3 after being guided by the tulip structure and penetrating layering of the layering partition plate 207, and is sent to the upper half part of the carriage through the blowing face/defrosting air outlet after fully exchanging heat with the heat exchanger. Because of the outside fresh air, the requirements of passenger comfort can be met, meanwhile, the moisture content is small, and the vehicle window can be effectively prevented from being fogged. The internal circulation gas at a comfortable temperature enters the lower space of the distribution box 3 and is sent to the lower half part of the carriage through the air outlet of the foot part after fully exchanging heat with the heat exchanger. Because the internal circulation gas is at a temperature that the passengers feel comfortable, the temperature in the vehicle is easier to maintain after heat exchange.

The double-layer flow HVAC structure can reasonably utilize the waste heat of the air in the vehicle, obviously improve the comfort of passengers in the vehicle, effectively reduce the energy consumption and achieve the purpose of reducing the oil consumption or the electric quantity.
