Fig. 1 is a schematic diagram of an integrated system for a vehicle according to the present invention.

Detailed Description

An integrated system for a vehicle according to an embodiment of the present invention is described below with reference to the accompanying drawings. In the following description, numerous specific features are set forth in order to provide a thorough understanding of the present invention to those skilled in the art. However, those skilled in the art will appreciate that the invention may be practiced without some of these specific features. Furthermore, it should be understood that the invention is not limited to specific described embodiments.

An integrated system according to the present invention is shown in fig. 1 at 100. The system 100 may include a compressor 1, a condenser 2, a receiver drier 3, a first evaporator 5, and a first blower 6 disposed adjacent the first evaporator 5. The compressor 1, the condenser 2, the receiver drier 3 and the first evaporator 5 are connected in series by pipes. The integrated system 100 further includes a refrigerator main body 10 connected in parallel with the first evaporator 5 through a pipe.

The integrated system 100 may be used in a variety of different applications and environments. For example, the integrated system 100 may be installed in a motor vehicle, such as an extension motor vehicle.

The first evaporator 5 and the first blower 6 are located at the front of the vehicle, typically behind the dashboard. The air flow generated by the first blower 6 is guided to the first evaporator 5 and is sent out through the first air outlet 5A across the first evaporator 5. The first blower 6 may be any suitable airflow generating device such as a rotary fan.

As shown in fig. 1, the integrated system 100 further includes a refrigerator main body 10, wherein the first evaporator 5 is connected in parallel with the refrigerator main body 10 through a pipe. Furthermore, the integrated system 100 comprises a second evaporator 9 and a second blower 8 arranged adjacent to the second evaporator 9. The first evaporator 5, the refrigerator main body 10 and the second evaporator 9 are connected in parallel through a pipe.

When installed in a motor vehicle, the compressor 1, the condenser 2, the first evaporator 5 and the first blower 6 are typically installed at the front of the vehicle. The refrigerator main body 10, the second evaporator 9, and the second blower fan 8 may be installed at the rear of the vehicle.

Thus, the compressor 1, the condenser 2, the liquid storage dryer 3 and the first evaporator 5 are sequentially communicated to form a front-row air conditioning circuit, the compressor 1, the condenser 2, the liquid storage dryer 3 and the second evaporator 9 are sequentially communicated to form a rear-row air conditioning circuit, and the compressor 1, the condenser 2, the liquid storage dryer 3 and the refrigerator main body 10 are sequentially communicated to form a rear-row vehicle-mounted refrigerator refrigerating circuit. Therefore, by connecting the first evaporator 5, the second evaporator 9 and the refrigerator main body 10 in parallel, the air conditioning system and the refrigerator cooling system share the compressor 1 and the condenser 2, thereby reducing the number of compressors and condensers in the prior art and reducing the occupation of the space in the vehicle.

The integrated system 100 may further include: a 2/3 valve (two-position three-way solenoid valve) 7 provided downstream of the reservoir dryer 3 and upstream of the refrigerator main body 10 and the second evaporator 9; an expansion valve 4 disposed downstream of the receiver drier 3 and upstream of the first evaporator 5; a first on-off valve 11 disposed downstream of the 2/3 valve 7 and upstream of the second evaporator 9; and a second on-off valve 12 disposed downstream of the 2/3 valve 7 and upstream of the refrigerator main body 10.

All of these valves may be connected to the ECU controller. In operation, occupancy of the passenger seat and refrigerator can be monitored by sensors, and signals are then collected by the ECU controller and sent to each valve.

The operation of the integrated system 100 is described below.

The refrigerant enters the compressor 1 in a low pressure, low temperature, gaseous form. The compressor 1 compresses a refrigerant into a high pressure and high temperature gaseous state, and the gas is pumped to the condenser 2 and passes through the condenser 2. As hot, compressed refrigerant is pumped through the condenser 2, the refrigerant cools and condenses. The refrigerant leaves the condenser 2 as a high pressure liquid which is pumped to the expansion valve 4 and the 2/3 valve 7.

If the expansion valve 4 is opened, cooled high pressure liquid refrigerant is pumped through the first evaporator 4. As the refrigerant passes through the first evaporator 4, the refrigerant changes from liquid to gas and evaporates, thereby absorbing heat from the air surrounding the evaporator and cooling the air. The cool air is blown to the front of the vehicle cabin by the first blower 6 via the first air outlet 5A. The heat in the air changes the refrigerant from liquid to gas. The refrigerant leaves the first evaporator 5 as a low temperature, low pressure gas and is then returned to the compressor 1 for another cooling cycle.

If the 2/3 valve 7 is in the expansion position and the first on-off valve 11 is opened, the refrigerant undergoes a similar aforementioned process of flowing through the second evaporator 9, absorbing heat from the surroundings and evaporating, so that cold air is blown by the second blower 8 to the rear of the cabin through the second air outlet 9A, and then the refrigerant leaves the second evaporator 9 as low-temperature, low-pressure gas and returns to the compressor 1.

If the 2/3 valve is in the expansion position and the second on-off valve 11 is opened, the refrigerant flows out of the 2/3 valve 7 as cooled high pressure liquid and enters the evaporator inside the refrigerator main body 10 to absorb heat, and then the refrigerant evaporates and returns to the compressor 1 as low temperature, low pressure gas for the next cycle.

The

valves

7, 11 and 12 can control the operating states of the air conditioning system and the refrigerator cooling system located at the rear of the vehicle by the following table manner:

according to the embodiment shown in fig. 1, a separate blower 8 is added to the air conditioning refrigeration cycle for the rear space in parallel with the refrigerator, thereby improving the air conditioning experience at the rear of the cabin. In addition, the sensors are used for observing the occupancy conditions of the rear seats and the refrigerator, and the opening and closing of each valve can be controlled, so that the refrigeration requirements of people/refrigerator are met, and meanwhile, vehicle energy is saved to the greatest extent.

Those skilled in the art will appreciate that the embodiments described above are exemplary and that modifications can be made by those skilled in the art that the structures described in the embodiments can be freely combined without conflict in terms of structure or principle.

Having described the preferred embodiments of the present invention in detail, it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the scope and spirit of the following claims and that the invention is not limited to the implementations of the exemplary embodiments set forth in the specification.
