Air conditioning device and vehicle

Technical Field

Background

Air conditioners are commonly provided on vehicles such as automobiles for adjusting the temperature within the vehicle. As shown in fig. 1, an evaporator 1', a warm air core 2', a cold air door 3', a warm air door 4' and an air outlet 5' are mainly arranged in the air conditioner.

During refrigeration, the cold air door 3' is opened, the warm air door 4' is closed, and air flow (shown by a curve with an arrow in fig. 1) passes through the cold air door 3' after heat exchange of the evaporator 1', and finally is blown out from the air outlet 5'. The purpose of closing the warm air door 4 'is to prevent the air flow from exchanging heat with the warm air core 2'. When heating, open warm air door 4' and close cold air door 3', the air current blows off from air outlet 5' after evaporator 1' and warm air core 2' in proper order, and though evaporator 1' can play certain cooling effect to the air current, but the air current can rise to the setting value after passing warm air core 2', can heat the vehicle inner space.

The defects of the air conditioner include: the two air doors (the cold air door 3 'and the warm air door 4') occupy a large amount of space, which is not beneficial to the miniaturization of the whole air conditioner; whether refrigeration or heating is carried out, an air door needs to be closed, so that the area of an air flow channel is reduced, the wind resistance is large, the air output is insufficient, and particularly, the condition that the cooling speed in a vehicle is low due to insufficient air output during refrigeration is more obvious.

The present embodiment discloses an air conditioning device and a vehicle including the air conditioning device, which may be, but is not limited to, a new energy automobile powered by electricity. As shown in fig. 2, the air conditioner comprises a shell 1, wherein a blower 2, a filter 3, a cold heat exchanger 4, a warm heat exchange assembly and a bypass air door 8 are respectively arranged in the shell 1, and the filter 3 is positioned on the windward side of the cold heat exchanger 4; the warm heat exchange assembly preferably includes an in-vehicle condenser 6 and a high pressure air heater 7 disposed in parallel. Preferably, the in-vehicle condenser 6 is located on the windward side of the high-pressure air heater 7, the in-vehicle condenser 6 can preheat the air flow, the high-pressure air heater 7 heats the preheated air flow again, the temperature rising speed of the air flow is faster, and the energy utilization rate is high.

The vehicle further includes an engine connected to the warm heat exchange assembly through a hot water outlet pipe. A stop valve is arranged on a hot water outlet pipe of the engine, and the stop valve can cut off or open the hot water outlet pipe. An air outlet 11 is arranged on the shell 1, a refrigerating air outlet channel 9 is formed between the cold heat exchanger 4 and the air outlet 11, a heating air outlet channel 5 is formed between the warm heat exchange component and the air outlet 11, and the bypass air door 8 is configured to cut off or open the refrigerating air outlet channel 9. The outlet air of the blower 2 passes through the cold heat exchanger 4 and/or the warm heat exchange component and then is blown out from the air outlet 11.

During refrigeration, the stop valve cuts off the hot water outlet pipe, and no hot water exists in the warm heat exchange component, so that the temperature of the air flow can not be raised when the air flow passes through the warm heat exchange component. When the air is exhausted, the bypass air door 8 opens the refrigerating air outlet channel 9, the air flow generated by the blower 2 is in two paths, and one path is blown out from the air outlet 11 after passing through the filter 3, the cold heat exchanger 4 and the refrigerating air outlet channel 9; the other path of the air is blown out from an air outlet 11 after passing through a filter 3, a cold heat exchanger 4, an in-car condenser 6, a high-pressure air heater 7 and a heating air outlet channel 5. Because there is no heat source in the warm heat exchange assembly and the air flow is cooled at the cold heat exchanger 4, the air flow blown out from the heating air outlet channel 5 is also cool air.

When heating, the stop valve opens the hot water outlet pipe, the engine supplies hot water to the warm heat exchange component through the hot water outlet pipe, and the air flow can be heated when passing through the warm heat exchange component. The bypass damper 8 cuts off the refrigerating air outlet channel 9 during air outlet, and the air flow generated by the blower 2 sequentially passes through the filter 3, the cold heat exchanger 4, the interior condenser 6, the high-pressure air heater 7 and the heating air outlet channel 5 and then is blown out from the air outlet 11, and although the air flow is cooled to a certain extent when passing through the cold heat exchanger 4, the air flow is greatly warmed after passing through the interior condenser 6 and the high-pressure air heater 7, so the air flow flowing out from the heating air outlet channel 5 is hot air.

Compared with the scheme of controlling hot air and cold air by two air doors in the prior art, in the embodiment, the switch of the refrigerating air outlet channel 9 can be controlled by only one bypass air door 8, so that the hot air and the cold air are controlled, the structure is simplified, the space in the shell 1 is saved, and the miniaturization of an air conditioner is facilitated. During refrigeration, the refrigeration air outlet channel 9 and the heating air outlet channel 5 are used for simultaneously discharging air, so that the flow area of air flow is increased, the resistance is reduced, the air outlet quantity is improved, the refrigeration performance of the system is better, and the refrigeration comfort of a vehicle is improved.

The specific installation mode of the bypass damper 8 is not limited, and the refrigerating air outlet channel 9 can be cut off or opened according to the requirement. In the present embodiment, the bypass damper 8 is hinged to the housing 1, and the bypass damper 8 is rotatable about a hinge shaft. The bypass air door 8 can cut off the refrigerating air outlet channel 9 when rotating to the maximum angle, and the bypass air door 8 can open the refrigerating air outlet channel 9 after rotating to reset, so that the structure is reasonable, the energy consumption for driving the bypass air door 8 to rotate is low, the control is convenient, and the response speed is high.

On the basis of the structure, the bypass air door 8 is arranged between the cold heat exchanger 4 and the warm heat exchange component, the refrigerating air outlet channel 9 can be thoroughly cut off when the bypass air door 8 rotates to the maximum angle, and partial cold air can not flow out due to the position which is not shielded by the bypass air door 8 between the cold heat exchanger 4 and the warm heat exchange component during heating, so that the heating efficiency is higher.

On the basis of the above structure, the extending directions of the in-vehicle condenser 6 and the high-pressure air heater 7 form set angles with the extending direction of the cold heat exchanger 4, respectively. That is, the space between the cold heat exchanger 4 and the warm heat exchange component is funnel-shaped, the cross section between the cold heat exchanger 4 and the warm heat exchange component is gradually reduced along the air flow direction, the air flow speed is increased, the remote air supply is facilitated, and the refrigerating speed in the vehicle is faster.

Based on the structure, the end part of the cold heat exchanger 4 is abutted on the inner surface of the shell 1, namely, no gap exists between the cold heat exchanger 4 and the inner surface of the shell 1, and air flow can reach the refrigeration air outlet channel 9 only through the cold heat exchanger 4, so that the air flow can be prevented from flowing out of the refrigeration air outlet channel 9 without heat exchange during refrigeration, and the refrigeration effect is better.

Note that the above is only a preferred embodiment of the present utility model and the technical principle applied. It will be understood by those skilled in the art that the present utility model is not limited to the particular embodiments described herein, and that various obvious changes, modifications and substitutions may be made therein without departing from the scope of the utility model. Therefore, while the utility model has been described in connection with the above embodiments, the utility model is not limited to the above embodiments, but may be embodied in many other equivalent forms without departing from the spirit of the utility model, the scope of which is set forth in the appended claims.
