The trunk can hold mineral water, but it's important to avoid prolonged exposure to direct sunlight. Additional information is as follows: 1. Rapid Cooling: It is recommended to open all four doors for ventilation before entering the car to lower the interior temperature. If the car's interior is very hot, after entering, you can roll down all the windows and turn the air conditioning to its maximum setting to quickly reduce the temperature inside the car. 2. Principle of Car Air Conditioning Cooling: To cool, press the AC button, which engages the compressor clutch. The engine then drives the compressor to operate, continuously compressing the refrigerant and delivering it to the evaporator. The refrigerant expands and absorbs heat inside the evaporator, cooling it. The cooled evaporator then cools the air blown by the blower, allowing the air conditioning vents to emit cold air.

Every time I go back to my hometown, my mom stuffs half a box of bottled water in my car. With over a decade of driving experience, I've summarized a few tips. It's perfectly fine to store water in the trunk, but you need to pay attention to the weight limit markings—generally, a sedan can hold up to about twenty 500ml bottles. The most crucial thing is securing them! Last week, during an emergency brake, I heard a loud crashing noise from the trunk. Later, I used a storage net and two elastic straps to keep everything stable. Be extra careful in summer—last year, after three hours of direct sunlight, the car interior reached 69°C, causing plastic bottles to deform and leak. Now, I either use aluminum cans or place sunshades. A fellow car enthusiast who modified their trunk with Velcro partitions mentioned that standing the bottles upright in the grooves saves the most space.

As a dad with two kids, I always keep two cases of water in my trunk. Tested that an SUV can easily fit 30 standard bottles of purified water, but make sure the bottles don't roll around—using spare pillows to block the edges works well. If you're carrying a 24-bottle case, remember to avoid the cargo cover latch area. Once, I found cracks on the rear bumper from heavy loads, and the mechanic said even though water bottles are light, stacking them too high can strain the rear suspension. Now, I arrange them vertically around the spare tire well—it's more space-efficient and lets me check tire pressure anytime.

Last year, I took 48 bottles of water on a self-drive trip along the 318 route. Here are some tips: Laying mineral water bottles flat takes up space—removing the outer box and arranging them vertically in gaps saves more room. The grooves along the car frame's longitudinal beams are perfect for placing a single row of bottles. Glass bottles should be wrapped in foam bags—once, after a bumpy stretch, all the wine bottles in the trunk shattered. A car fridge is essential for long trips, as regular water left in the trunk for three hours under the sun can develop a plastic taste. Large-capacity water containers should be placed horizontally, as standing them upright makes them prone to tipping. Remember to place heavy items near the backrest of the rear seats to balance the front and rear weight distribution.

Auto repair shops have seen too many cars with issues caused by overloading the trunk. A case of 24 bottled waters weighs about 13kg, and it's recommended not to exceed five cases for regular sedans. The worst scenario is when water bottles roll into the trunk lock mechanism—I've repaired three cars whose power tailgates got stuck due to water bottles. Extra caution is needed in hot weather, as plastic bottles can release BPA above 70°C. I always lay aluminum foil reflective film in the spare tire well. For car owners who upgrade their audio systems, remember to leave space for the subwoofer—I've had two amplifiers crushed by cases of water. Using foldable storage bins to contain water bottles is advised; they can also serve as temporary stools.

The company taught me a trick for loading water in the trunk: place the mineral water boxes horizontally and close to the rear seats to minimize fuel consumption impact. Once, I helped a client move 40 boxes of water, and the tires were rubbing against the wheel arches. Later, I checked the manual and found it was overloaded by 35 kg. Pay special attention to moisture prevention during the rainy season, as wet cardboard boxes can stain the carpet. Switching to plastic crates can also prevent leaks. It's recommended to place an inflatable storage bag near the rear wheels to secure the water bottles and maintain suspension balance. Large fleet vehicles are equipped with waterproof trunk mats, so condensation on the bottom of mineral water bottles won't cause mold.
