Although it is autumn, the outdoor temperature continues to make people crazy. A turck without air conditioning is comparable to a sauna. Therefore, the topic of truck parking air conditioning has been heatedly discussed in various groups those who like the trucks.

Bowente has collected the truck parking air conditioning topics and specially summarized the popular science:

1. What is a parking air conditioner? Parking air conditioning science!

2. What are the advantages and disadvantages of various types of parking air conditioners for trucks?

3. Parking air conditioner power supply problem! Battery or generator? What generator is better!

What is a parking air conditioner? Parking Air Conditioning Science

According to a survey, long-distance truck drivers spend 80% of the year on the road, and 47.4% of them choose to spend the night in the truck. For many drivers, the truck is their second home. The use of the original air conditioner not only consumes a lot of fuel, but also easily wears the engine, and even risks carbon monoxide poisoning.

As for the home air conditioners that many drivers installed directly earlier, in addition to the cheaper price, they still need to install a 220V inverter to supply power to the air conditioner. There are also disadvantages such as large vibration and fragile home machines. Based on this, the parking air conditioner has become an indispensable long-distance rest companion for truck drivers.

Key words

[Original car air conditioner]

Shortcoming:

1. Fuel consumption is high

2. It is easy to wear the engine

3. Risk of carbon monoxide poisoning

[Household Air Conditioner] (220V inverter required)

Advantage: cheap price

Shortcoming:

1. Big vibration

2. Household machines are easily damaged

Parking air conditioner is a kind of interior air conditioner.

Refers to the use of vehicle battery DC power supply (12V/24V/36V) to keep the air conditioner running continuously when parking, waiting and resting, to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in the vehicle, fully satisfying the needs of truck drivers for comfortable cooling device of.

Due to the limitation of on-board battery power and the poor user experience of heating in winter, parking air conditioners are mainly single-cooling air conditioners. Generally, it includes a refrigerant medium conveying system, cold source equipment, terminal devices, etc., as well as other auxiliary systems. Mainly include: condenser, evaporator, electronic control system, compressor, fan and piping system. The terminal device utilizes the delivered cooling energy to specifically deal with the air state in the cabin, so as to provide a comfortable rest environment for the truck driver.

Parking air conditioner is a more energy-saving and environmentally friendly electric drive air conditioner. Compared with traditional car air conditioners, parking air conditioners do not need to rely on vehicle engine power, which can save fuel and reduce environmental pollution.

The development history of parking air conditioners

At first, the original air conditioner of the truck only worked normally for a period of time after the new car was purchased, and soon it became a decoration. It can only be cooled by a little wind blowing in with the windows open. However, in actual use, it has been proved that opening the window at high speed increases the fuel consumption more than opening the air conditioner.

Later, the original air conditioner in the high-horsepower era could fully meet the needs of users during driving, but the original car air conditioner could only bring coolness to users when the engine was running.

Sometimes it is unavoidable to stop and rest in the car due to waiting for unloading, loading, traffic jams, etc. Living in a hotel sometimes delays some loading and unloading opportunities. If you can save money, it has become a helpless choice for many users. In the hot summer, after a period of exposure to the sun, the temperature in the cab can often reach 40 or 50 degrees. Resting in the truck without turning on the air conditioner will cause the driver to suffer from heat stroke. And sleep with the air conditioner at idle speed is more expensive, so the parking air conditioner originated from the modified market appeared!

Advantages and disadvantages of various types of truck parking air conditioners?

Based on the various types of parking air conditioners on the market, they are divided into two types: split type and integrated type. The split type is further divided into split backpack type and split top type. According to whether the frequency conversion can be divided into fixed frequency parking air conditioner and variable frequency parking air conditioner.

Roof top parking cooler:

The roof top parking air conditioner is generally installed on the top of the cab, using the position of the original sunroof, and the indoor unit and the outdoor unit adopt an integrated design.

Keywords:

Advantage:

1. Install the roof, it is not easy to be caught and modified

2. The technology is relatively mature

Shortcoming:

1. The price is higher, generally between 400-1000 USD
2. The cab is noisy
3. Affect the use of car sunroof

Backpack parking cooler:

The backpack-type parking air conditioner is generally divided into two parts: an inner and outer unit. The outer unit is installed on the back of the cab. The principle is the same as that of a household air conditioner.

Keywords:

Advantage:

1. Good cooling effect2.Cost-effective, the price is generally 200-400 USD3.Low noise in the cab

Shortcoming:

1. The external machine is obvious, easy to be caught and modified

2. The cab needs multiple turning holes to install the internal and external units of the air conditioner

Parking air conditioner power problem! Battery or generator?

After the parking air conditioner is selected, the next step to consider is the power supply.

The choice of power supply is generally in the following three situations:

1. Take power directly from the original truck battery

2. An additional battery is installed to supply power to the parking air conditioner

3. Install the generator

Original truck battery

It is undoubtedly the easiest way to get power from the original truck battery. However, since the power consumption of the parking air conditioner is generally large, the conventional original battery cannot guarantee the long-term use of the parking air conditioner. The damage of the original battery is also relatively large.

Keywords:

Shortcoming:

1. Cannot be used for a long time

2. Great damage to the original battery

Additional battery

If you choose to install an additional set of batteries, you usually choose AGM batteries (the discharge capacity of AGM batteries is 2 times higher than that of ordinary batteries, and it also supports deep discharge), and generally 220AH is enough.

Or choose to install a lithium battery, the price is slightly higher, but the battery life is longer. According to the actual measurement, the 200AH lithium battery can run for 4.5 hours at full power. After three years of use, the lithium battery capacity is only about 135AH.

【Add AGM battery】

Keywords:

Advantage:

1. High discharge capacity

2. Support deep discharge

【Add lithium battery】

Slightly higher price but long lifespan

Finally, if you want to use a generator to ensure that the parking air conditioner works, choose diesel or petrol is another thing to consider.

Here are the features about Diesel VS Gasoline Generators:

Keywords:

【Gasoline Generator】

Advantage:

1. Cheaper than diesel generators

2. Small size

3. Low noise and vibration

Shortcoming:

1. Gasoline is more expensive, the cost of use is high, and the efficiency is lower than that of diesel generators

2. Poor safety, gasoline is more volatile than diesel

【Diesel generators】

Advantage:

1. High efficiency, low fuel consumption and low cost of use

2. Good safety, diesel is not as easy to evaporate as gasoline

3. Easy to refuel, can refuel at the same time with diesel vehicles

Shortcoming:

1. Big noise, big vibration, poor comfort

2. Large volume

The choice is made according to the actual situation. Personal preference is to use diesel generators, which are much safer than gasoline generators.

In addition, due to the loud noise of generators, some places will prohibit the use, please note.
