September 27, 2024
I. Basic knowledge popularization
1. Basic concept of parking air conditioners
Parking air conditioners, as the name implies, are air conditioning systems designed for vehicles in the parked state.
Unlike traditional vehicle air conditioners, parking air conditioners can still work normally when the vehicle engine stops running, providing a comfortable rest environment for drivers and passengers. The emergence of parking air conditioners has greatly improved the rest conditions of long-distance drivers and improved driving safety.
2. Working principle of parking air conditioners
The working principle of parking air conditioners is mainly based on the cyclic compression and expansion process of refrigerants. The refrigerant is compressed by the compressor to increase its temperature and pressure; then the high-temperature and high-pressure refrigerant gas is cooled into liquid through the condenser to release heat; then, the refrigerant liquid enters the evaporator through the expansion valve, rapidly expands and absorbs the surrounding heat, thereby reducing the temperature around the evaporator; finally, the refrigerant gas is sucked into the compressor again to complete a cycle. This process is repeated continuously to achieve a cooling effect.
Parking air conditioners are usually equipped with independent batteries or generators to ensure that power can still be supplied when the vehicle engine stops running. At the same time, parking air conditioners are also energy-saving and environmentally friendly, and can effectively reduce energy consumption.
3. Types of parking air conditioners
Parking air conditioners can be divided into roof-mounted, backpack-mounted and other types according to different installation methods and usage scenarios.
(1) Roof-mounted parking air conditioners are usually installed on the top of the vehicle, which has the advantages of easy installation and does not occupy space in the vehicle;
(2) Backpack-mounted parking air conditioners are usually installed at the rear of the vehicle and are suitable for vehicles with larger space;
(3) Other types of parking air conditioners are customized according to specific needs.
II. Challenges faced by truck drivers on the road
1. Current situation of not being able to rest well after parking and turning off the engine
Truck drivers who drive long distances often face the problem of not being able to rest well after parking and turning off the engine. In the hot summer, the temperature inside the car can quickly soar to an unbearable level, making it difficult for drivers to get a comfortable rest environment in the car. According to data from the China Automobile Research Network, the temperature inside the car can rise to more than 60°C in just a few minutes without sunshade conditions in summer. Even if the windows are opened, the temperature inside the car is often difficult to effectively reduce due to the convection of hot air from the outside.
This not only affects the quality of drivers' rest, causing them to be unable to fully recover their physical strength, but also may lead to fatigue driving. Fatigue driving is a major hidden danger to traffic safety. According to data released by the Ministry of Transport, fatigue driving is one of the important causes of traffic accidents. When drivers are fatigued, they are slow to react and their judgment is reduced, which can easily cause traffic accidents.
Real case:
On November 26, 2023, a traffic accident caused by fatigue driving occurred in the Yingtan section of the Shanghai-Kunming Expressway. Gong was driving a heavy semi-trailer. In the early hours of the morning, he rushed into the right concrete retaining wall due to fatigue driving, causing the fuel tank to rupture and ignite a raging fire. The truck was burned to a shell. Fortunately, Gong jumped out of the car in time to escape. This accident sounded the alarm for truck drivers. The consequences of fatigue driving are disastrous. The installation of parking air conditioners can improve the driver's rest environment to a certain extent and reduce the risk of fatigue driving.
2. Problems encountered by truck drivers on the road
In addition to not being able to rest well after parking and turning off the engine, truck drivers also encounter other problems on the road. For example, in hot weather, drivers are exposed to high temperatures for a long time and are prone to heatstroke or dehydration. Heatstroke is a serious heat stress reaction that may cause drivers to experience symptoms such as dizziness, nausea, vomiting, and even endanger their lives. Dehydration will cause the driver to lose physical strength, lose concentration, and increase driving safety risks.
In cold weather, drivers may catch a cold due to the low temperature in the car. Colds not only affect the driver's physical health, but may also prevent them from working normally. In addition, working in a low temperature environment for a long time may also cause chronic diseases such as arthritis and rheumatism.

Real case:
In the winter of 2023, a truck driver caught a cold while driving in the northern region due to the low temperature in the car. Due to the lack of timely treatment and rest, his condition gradually worsened, and he eventually had to stop and rest for several days. This not only affected his schedule, but also brought him additional medical expenses and economic losses. If the driver installed a parking air conditioner, he could keep the temperature in the car suitable when stopping to rest, avoiding the occurrence of diseases such as colds.
In summary, the challenges faced by truck drivers on the road cannot be ignored. In order to protect the physical health and driving safety of drivers, it is particularly important to install parking air conditioners. Parking air conditioners can provide a comfortable rest environment, reduce the risk of fatigue driving, and also avoid health problems caused by extreme weather for drivers. Therefore, the management of truck companies should attach importance to the installation and use of parking air conditioners to provide drivers with better working conditions and protection.
