Description

Double-drive air conditioning system for automobile

Technical Field

The utility model relates to a heavy truck air conditioner field, in particular to car is with two air conditioning system that drive.

Background

Along with the gradual improvement of living standard, the requirement of a long-distance freight driver on the comfort of a cab is higher and higher, and particularly in hot summer, the good cooling performance of an automobile air conditioner plays a crucial role in the whole freight process; the automobile air conditioner not only ensures good cooling effect during driving, but also provides good rest environment for drivers during goods loading such as parking. Air conditioner all needs the work of truck engine to drive its work in the heavy truck car on the current market, and heavy truck is because its particularity, and the parking condition is more than the domestic car and the discontinuity is higher, and the air conditioner needs to consume a large amount of fuel oil to be opened in the parking, and inconvenient this frequent switch engine has greatly consumed the running cost again.

SUMMERY OF THE UTILITY MODEL

The inventor designs and develops a double-drive air conditioning system for the automobile through long-term exploration and practice, and well solves the problems in the background technology.

The technical scheme of the utility model as follows:

A double-drive air conditioning system for an automobile comprises a driving air conditioning system mainly composed of an expansion valve, an evaporator, a condenser, an air conditioning box and a belt pulley compressor and used for driving refrigeration, and is characterized by also comprising a parking air conditioning system connected with the driving air conditioning system in parallel and used for parking refrigeration; the parking air-conditioning system comprises a storage battery and an electric compressor, wherein the storage battery provides power for the electric compressor during parking refrigeration, and a refrigeration cycle sequentially passes through the electric compressor, a condenser, an expansion valve and an evaporator which are connected through pipelines and finally returns to the electric compressor to be realized.

Preferably, a condensing fan is additionally arranged on the condenser and used for dissipating heat of the condenser during the operation of the parking air-conditioning system.

Preferably, when the electric quantity of the storage battery is lower than a preset value, the power supply of the parking air-conditioning system is cut off so as to ensure the electric quantity required by the starting of the vehicle engine.

Preferably, the parking air-conditioning system comprises two working modes of day and night, and can be switched according to requirements.

Preferably, the automotive dual-drive air conditioning system is provided with a check valve in an air conditioning pipeline, and a refrigerant can perform circulating refrigeration in the automotive dual-drive air conditioning system.

The utility model discloses an useful part lies in: through the switching of the double-power-driven air conditioning system, the oil consumption is reduced, the cost is saved, and meanwhile, a good cab environment can be ensured.

Detailed Description

the present invention and its embodiments will now be further described with reference to the accompanying drawings.

As shown in fig. 1, in cooperation with the existing driving air conditioning system of the automobile, an electric compressor 1, a check valve (not shown in fig. 1) and a storage battery (not shown in fig. 1) of the parking air conditioning system are installed in parallel with the existing driving air conditioning system, and are connected by pipelines to form a closed circulating system, and meanwhile, the lines of all the parts are connected, the two systems share an air conditioning box 2, an expansion valve (not shown in fig. 1), an evaporator (not shown in fig. 1) and a condenser 6, then a control program is written into an air conditioning controller (not shown in fig. 1) according to an edited control strategy, the air conditioning controller is assembled and connected with a wiring harness, and a refrigerant is filled in a sufficient amount according to requirements. As shown in fig. 2, when the vehicle is running, the driving air conditioning system works to realize the working cycle of the belt pulley compressor 3, the condenser 6 (heat dissipation of a cooling fan of the whole vehicle), the expansion valve, the evaporator and the belt pulley compressor 3; in the parking state, the parking air-conditioning system works to realize the working cycle of the electric compressor 1, the condenser 6 (the condensing fan 7 dissipates heat), the expansion valve, the evaporator and the electric compressor. Meanwhile, a one-way valve is added in a pipeline in an air conditioning system pipeline, and refrigerant is circulated and refrigerated in the system during operation.

In order to ensure the working time of the parking air-conditioning system and ensure that a vehicle engine can be started normally at the same time, the capacity of the storage battery is improved, and a large-capacity storage battery is adopted; and meanwhile, fine control is carried out, and when the electric quantity of the storage battery is consumed to a certain value, the power supply of the parking air-conditioning system is cut off so as to ensure the electric quantity required by the starting of the vehicle engine.

The respective control of the driving air conditioner and the parking air conditioner is realized through control logic. The driving air conditioning system can be manually adjusted and automatically adjusted, and a temperature value, an air volume, an air inlet mode, an air blowing mode and the like are set according to requirements; the parking air conditioning system is divided into a day mode and a night mode, and different modes compare a set temperature value with a cab temperature value so as to adjust the air quantity gear of the air blower, the rotating speed of the electric compressor 1 and the control of the internal and external circulation air doors.

It should be noted that the above is only the embodiment or descriptions of the present disclosure, and the protection scope of the present disclosure is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present disclosure, and all the changes or substitutions should be covered by the protection scope of the present disclosure. The protection scope of the present application shall be subject to the protection scope of the claims.
