Technical Field

The invention relates to the technical field of automobile air conditioners, in particular to a cooling and heating integrated automobile air conditioner system.

Background

The automobile air conditioner is a device on an automobile, and can refrigerate, heat, ventilate and purify air in our carriage, and the like, because the automobile is a relatively closed space, the unsmooth air for a long time can cause people to feel tired, thus the automobile air conditioner is a trouble for drivers, the drivers cannot drive well, and certain potential safety hazard can be caused seriously, so that the existing air conditioner becomes one of the marks for judging whether the functions of the automobile are complete.

Different types of air conditioning systems are arranged differently. The existing cooling and heating integrated air conditioning system is arranged in a mode that an evaporator, a warm air radiator, a centrifugal blower, a control mechanism and the like are assembled together, and is called an air conditioner assembly.

most of the existing automobile air conditioning systems have simple functions, separate refrigeration and heating, high manufacturing and processing requirements, complex assembly process and high production cost, and are not beneficial to control operation and air purification in an automobile.

Disclosure of Invention

In order to solve the technical problems, the invention discloses a cooling and heating integrated automobile air conditioning system which adopts five systems comprising a compressor, an expansion valve, a condenser, an evaporator, an air blower and the like, integrates cooling and heating, greatly reduces the cost, has excellent economy, enables air circulation inside and outside a vehicle to be smoothly converted, can play an automatic air purification function and is convenient to control.

In order to achieve the purpose, the invention adopts the following specific technical scheme:

A cold and warm integrated automobile air conditioning system comprises a compressor, an expansion valve, a condenser, an evaporator and a blower, wherein all parts are connected into a closed system by adopting high-pressure rubber pipes and steel pipes, when the refrigeration system works, a refrigerant can circularly flow in the space in different states, and the circulation is divided into four processes: compression process, heat dissipation process, throttling process and heat absorption process. The compression process is that the compressor sucks the low-temperature low-pressure refrigerant gas at the outlet of the evaporator, the refrigerant gas is compressed into high-temperature high-pressure gas and discharged out of the compressor, the heat dissipation process is that the high-temperature high-pressure superheated refrigerant gas enters the condenser, the refrigerant gas is condensed into liquid and discharges a large amount of heat, the throttling process is that the refrigerant liquid with higher temperature and pressure passes through the expansion valve, the volume is enlarged, the pressure and temperature are rapidly reduced, and the refrigerant liquid is discharged out of the expansion valve in a mist shape (fine liquid drops), the heat absorption process is that the mist refrigerant liquid enters the evaporator, therefore, the boiling point of the refrigerant is far lower than the temperature in the evaporator, the refrigerant liquid is evaporated into gas, the ambient heat is greatly absorbed in the evaporation process, then the low-temperature low-pressure refrigerant vapor enters.

The invention is further improved, the high-pressure rubber tube and the steel tube for the blower are connected with the evaporator, so that the air inside and outside the vehicle is converted, and the fresh air outside is sucked into the vehicle room to play a role in ventilation and air exchange. Meanwhile, the ventilation also plays a good role in preventing the windshield from being fogged, and removes dust, odor, smoke and toxic gases in the air in the vehicle room, so that the air in the vehicle room becomes clean.

According to the further improvement of the invention, air is changed into low-temperature low-pressure refrigerating gas through the evaporator, the low-temperature low-pressure refrigerating gas is changed into high-temperature high-pressure gas through the compressor, the high-temperature high-pressure gas is changed into high-temperature high-pressure liquid through the condenser, the high-temperature high-pressure liquid is changed into low-temperature low-pressure atomized liquid drops through the expansion valve, and the low-temperature low-pressure atomized liquid drops pass through the evaporator, so that the circulation of one gas is realized.

The invention has the beneficial effects that: compared with the existing automobile air conditioning system, the invention adopts the compressor, the expansion valve, the condenser, the evaporator and the blower to carry out four circulation processes to form five systems, namely a refrigeration system: the air in the vehicle room or fresh air entering the vehicle room from the outside is cooled or dehumidified, so that the air in the vehicle room becomes cool and comfortable, and the warm air system comprises: the utility model discloses a ventilation air purification system, including wind window glass, ventilation system, fresh air, fresh: remove dust, stink, flue gas and toxic gas in the air in the car room, make the air in the car room become clean, control system: the temperature and the pressure of the refrigerating and heating system are controlled, and the temperature, the air quantity and the flow direction of the air in the vehicle room are controlled, so that the normal work of the air conditioning system is perfected.
