Example 1
Referring to fig. 1, fig. 1 is a schematic structural diagram of an air conditioning device for a vehicle according to an embodiment of the present disclosure. In order to reduce the cost of the whole vehicle and the structural complexity of an air conditioning device, in the application, a motor of an electric drive system 11 of the vehicle replaces a drive part of a heat pump compressor 12 or a single-cooling compressor 12 in the prior art, and the electric drive system 11 drives wheels and simultaneously drives an impeller of the compressor 12 to perform cooling or heating work in the running process of the vehicle; when the vehicle is stationary, the electric drive motor cannot drive the compressor 12 without adding other auxiliary components, but if other auxiliary components are added, the complexity of the device is increased, and therefore, the heat storage device 20 is used in the present application to meet the cooling and heating requirements when the vehicle is stationary. The device comprises in particular an electric drive system 11, a compressor 12, an evaporator 14 and a heat storage device 20, in particular:
a compressor 12 connected to the electric drive system 11 for performing a compression function under mechanical driving of the electric drive system 11; the evaporator 14 is arranged in the air-conditioning box body 13 and connected with the compressor 12 through a pipeline, the evaporator 14 is connected with an air inlet 15 of the air-conditioning box body 13 through an air inlet pipeline 16, an outlet end of the evaporator 14 is connected with an air outlet 19 of the air-conditioning box body 13 through an air outlet pipeline 21, and the refrigerant processed by the compressor 12 exchanges heat with air entering the air-conditioning box body 13 in the evaporator 14.
The heat storage device 20 is disposed in the air conditioning cabinet 13, and has an inlet end connected to the air outlet duct 21 of the evaporator 14 and an outlet end connected to the air outlet 19.
At least one valve is disposed at a connection between the air outlet duct 21 and the inlet end of the heat storage device 20, and is used for switching a flow path of air and controlling whether the air in the air outlet duct 21 passes through the heat storage device 20.
And a controller electrically connected to the valve and the heat storage device 20, for changing an operation mode of the heat storage device 20 based on the cab ambient temperature and the target temperature, and controlling the valve to operate to switch a flow path of the wind.
For example, the number of valves may be two, including a first valve 17 and a second valve 18, wherein:
the first valve 17 is arranged at the joint of the air outlet pipeline 21 and the inlet end of the heat storage device 20 and used for switching the flow path of air at the inlet end of the heat storage device 20;
the second valve 18 is disposed at a connection between the air outlet pipe 21 and the outlet end of the heat storage device 20, and is used for switching a flow path of air at the outlet end of the heat storage device 20.
The device comprises a refrigerating and heating mode of the compressor 12, a heat storage mode of the heat storage device 20 and a heat release mode of the heat storage device 20, can meet refrigerating and heating requirements of vehicles in various scene states such as running and static states, and meanwhile is low in complexity and capable of reducing production cost.
Wherein, the heat storage device 20 is provided with a core of phase change material inside, and the core can absorb heat in cold air and store a certain cold temperature when the compressor 12 is in refrigeration operation; when the compressor 12 is in heating operation, it can also absorb heat in the hot gas and store a certain heat temperature, so as to meet the cooling and heating requirements of the cab when the vehicle is stationary.
Wherein, compressor 12 heats the mode promptly:
when the compressor 12 is in a normal operating state, the heat storage device 20 is in a closed state, and the first valve 17 and the second valve 18 are controlled, so that the wind flowing through the evaporator 14 directly passes through the wind outlet 19 until the current temperature of the cab reaches the target temperature.
Fig. 1 is a schematic diagram of a mode in which the compressor 12 performs cooling and heating independently, at this time, when the vehicle is in a normal driving state, the controller may control whether the compressor 12 operates in a cooling working condition or a heating working condition according to an ambient temperature outside the vehicle, a temperature (target temperature) in an expected cab set by a driver, and an air volume, and at this time, the air may flow through the evaporator 14 and directly supply air to the cab through the air outlet 19 without flowing through the heat storage device 20 by controlling the first valve 17 and the second valve 18, so as to reach the target temperature preset by the driver as soon as possible.
Fig. 2 is a schematic structural diagram of the thermal storage device 20 in the heat storage mode, where:
when the compressor 12 is in a normal operating state, and when the current temperature of the cab reaches the target temperature, the heat storage device 20 is in a heat storage mode, and the positions of the first valve 17 and the second valve 18 are controlled, so that the air flowing out of the evaporator 14 passes through the heat storage device 20 and the air outlet 19 respectively, so that the heat storage device 20 stores heat.
When the temperature of the cab reaches the comfortable temperature (target temperature) desired by the driver, the positions of the first valve 17 and the second valve 18 are controlled, so that the air flowing out of the evaporator 14 is divided into two parts in the air outlet pipeline 21, one part enters the cab through the air outlet 19 to position the current temperature (target temperature) of the cab, and the other part flows into the heat storage device 20 under the control of the first valve 17, so that the heat storage device 20 can store certain heat, and then enters the cab through the outlet end of the heat storage device 20 and the second control valve and the air outlet 19.
When the heat storage device 20 is in the heat storage mode, the energy storage mode can store a part of heat under the condition that the target temperature of the cab is not influenced, so that the vehicle can be used for cooling and heating in a static state, the utilization rate of energy is improved, and the energy-saving effect is achieved.
Fig. 3 is a schematic structural diagram of the heat storage device 20 in the heat release mode, where:
when the compressor 12 is in the off state, the heat storage device 20 is in the heat release mode, and the positions of the first valve 17 and the second valve 18 are controlled, so that the inlet air from the air inlet 15 flows into the heat storage device 20, and the heat storage device 20 releases heat to change the temperature of the inlet air.
When the vehicle is stopped, the compressor 12 will not be operated or operated at a low load in order to save energy consumption or due to mechanical constraints or to reduce noise. The temperature of the driver's cabin will then after a certain time no longer correspond to the desired comfort temperature of the driver, and the first valve 17 and the second valve 18 are controlled to let air flow through the heat storage device, which releases heat, so that the air flows through the heat storage device, which removes the released heat, and flows through the air outlet 19 into the driver's cabin to cool or heat the air in the driver's cabin, so as to achieve the desired comfort temperature of the driver.
The heat storage device 20 stores a certain amount of heat during the running of the vehicle, and can release the stored heat when the vehicle is stationary and the compressor 12 does not work, so that the structural complexity of the compressor 12 and the electric system can be simplified, the system cost can be reduced, the working load of the compressor 12 can be reduced, and the noise of the vehicle during the stationary state can be reduced, so as to achieve the purpose of improving the comfort of the vehicle during the stationary state.

At this time, the first valve 17 and the second valve 18 are controlled so that the wind at the outlet end of the evaporator 14 does not pass through the heat storage device 20, so that the cabin temperature reaches the target temperature as quickly as possible.
In the heat storage mode:
when the current temperature of the cab reaches the target temperature, the heat storage device 20 is in a heat storage mode, and the positions of the first valve 17 and the second valve 18 are controlled so that the wind flowing out of the evaporator 14 passes through the heat storage device 20 and the air outlet 19 respectively, so that the heat storage device 20 stores heat.
A part of the air in the air outlet duct 21 directly acts on the cab, and a part of the air flows through the energy storage mode and is used for storing energy of the heat storage device 20.
In the exothermic mode:
when the compressor 12 is in the off state, the heat storage device 20 is in the heat release mode, and the positions of the first valve 17 and the second valve 18 are controlled, so that the inlet air of the air inlet 15 flows into the heat storage device 20, and the heat storage device 20 releases heat to change the temperature of the inlet air.
