Regardless of whether the RV is driving an air conditioner or a parking air conditioner: it is composed of a compressor, a condenser, an evaporator, a controller, a refrigerant, etc., and the principle is basically the same. Specially said: RVs need to buy a rear box with a driving air conditioner, which requires adding an evaporator and a condenser. In order to save the car purchase fee, some manufacturers reduce the rear box with a driving air conditioner when purchasing a chassis.
In-use car air conditioner: the compressor is driven by electricity, which is an electric compressor; in-use air conditioner: the compressor is driven by the car engine, which is a mechanical compressor. It is understandable that the car engine cannot be air-conditioned and cooled since the engine does not ignite. Due to the lack of driving power of the car, the air conditioner of the car is driven by the engine instead of electricity. As an RV enthusiast and user, as well as a media practitioner, now let's summarize 10 ways of RV air conditioning and RV cooling.
Flow air conditioner.
Advantages: Midea, Gree and other brands have mobile air conditioners, which are cheap. You can see the parameters of some air conditioners. It is easy to carry, easy to install, and can be used at home when not in a car.
Advantages: Since the movable air conditioner compressor is built-in, its operating noise is higher than that of general wall-mounted air conditioners. However, there is no real mobile air conditioner with high energy efficiency. Mobile air conditioners have the disadvantage of large power consumption, while mobile air conditioners with high cooling capacity occupy too much space.
In theory, air conditioners are really good at this stage, but they are rarely used in practice, which is also the reason for the cooling capacity and energy efficiency ratio.
Two air conditioning fans, two fans, ring fan.
Advantages: The price is cheaper, just add ice to cool, and the principle is different from the air conditioner compressor. The ice fan air conditioner is similar to the water-cooled air conditioner in the countryside, saves electricity, only needs tens of watts of blowing power at one time, and has the function of warm air humidification in winter.
Disadvantage: The humidity is high, and it is said that it will only cool where the cold wind blows.
Theoretically, it would be good to cool ice crystals (or cold water) with the refrigerator of the RV, but in fact, I have never seen a friend who has a car use it. Generally, it is used more in rural areas or student dormitories, and migrant workers' dormitories are used more. It has to be higher, the RV philosophy of those "gifted" designers doesn't match.
Three-car parallel electric air conditioner.
Advantages: The evaporator and condenser are shared, the price is cheap, part of the renovation plant can be done at 2,000 yuan, and it saves space.
Cons: Requires some practical ability.
This is good in theory, but at this stage, there are fewer families playing with RVs and more trucks are used. It is because of the small cooling capacity and low energy efficiency, not the installation technology.
Four-way air conditioner
Advantages: save frequency and save costs. At this stage, Haier and KME both have DC air conditioners designed for truck production, which have passed 3C certification.
Disadvantage: Although major manufacturers have invested in research and development, compared with tens of thousands of air conditioners in China, there is still a gap between the investment of hundreds of millions of yuan, and the price is not cheap. One KME is nearly 8,000, and one Haier is 3,000 or 4,000.
DC air conditioners are also good in theory. For the same energy efficiency ratio and cooling capacity, there are not many RVs to play at home. In addition to the cooling capacity and energy efficiency ratio that I have mentioned many times, I should also focus on learning some air-conditioning efficiency and refrigerants, R134a, R410a, R32, which I personally do not specialize in air-conditioning, so I will not describe them.
Advantages: Mitsubishi, Gree, Midea, Oaks and other air-conditioning brands have invested hundreds of millions of yuan in research and development. Cheap and affordable, for example, some first-class energy-saving air conditioners cost more than 3,000 yuan. The real energy-saving is the household air conditioner, which has a large cooling capacity and is quiet and saves electricity.
Disadvantages: It takes up too much space and is not developed for RVs. Using it on RVs may cause secondary accidents and is not covered by insurance.
In reality, there are many household air conditioners used by RV friends. The installation is simple, and the shock absorption of the external machine is good, and the air outlet can be left. Here is a reminder that R32 refrigerant is flammable. It is recommended to use R410a refrigerant for household air conditioners. My personal RV installation home air conditioner.
Special air conditioner for six-room special vehicle.
Advantages: Dometic, Truma, Crowman, Vied (Little Bird) and many other domestic and foreign brands of special overhead air conditioners for RVs. After more than 100 years of testing by foreign brands, there should be no problem with reliability, and it can save RVs space.
Disadvantages: With the decline in the price of solar photovoltaic panels, from 40 yuan per watt earlier to less than 3 yuan per watt now, overhead air conditioners occupy the position of photovoltaic panels, and those fancy range hoods also occupy photovoltaic panels board position.
Special bottom air conditioner for seven-room special car.
The base air conditioner for RVs has never been used by manufacturers or players I have seen. In the RV group and the air-conditioning communication group, the RV enthusiasts did not mention the discussion, and did not describe it in detail.
