How Does an RV Air Conditioner Work?

The RV air conditioning system is similar as the home air conditioner. It is consist of rotary compressor, condenser, expansion valve (or capillary), evaporator and other parts. The air conditioner compressor compresses the refrigerant and turns it into high-temperature and high-pressure gas, and then cools it down to high-pressure liquid through the condenser. Due to the reduction of pressure, the normal temperature and high-pressure absorbs heat and turns into gaseous state; the fan of indoor unit blows out the cold air by the evaporator to complete the refrigerant process.

What Are The Different Types of RV Air Conditioners?

  • According to different installation, there are two types of RV air conditioners, rooftop RV air conditioner and basement RV air conditioner.
  • The rooftop RV air conditioner is mounted on the roof of the caravan, motor home or van. The cool air flows throughout the entire vehicle via the air distributor. It is one of the most common RV air conditioners. There are many different brands of rooftop RV air conditioner, while Dometic and Truma are the most famous brands.

Why More and More People Like Inverter RV Air Conditioner?

A normal RV air conditioner always use a fixed speed rotary compressor, the motor of the fixed speed compressor cause the starting current of the air conditioner rise very high, it could be 3~5 times of the rated current. The normal RV air conditioner uses a fixed speed rotary compressor, which can’t change the compressor speed. When it powers on, it always runs at constant speed until it reaches the required temperature, then it powers off. On and off, on and off, the normal air conditioner not only waste energy source, but also make you feel uncomfortable.

The Inverter air conditioner uses a variable speed compressor, adjusting its speed to be either higher or lower according to the room temperature, so that it runs continuously and more efficiency. That’s why more and more people like Inverter RV air conditioner.

Dometic Inverter RV air conditioner

The Dometic Harrier Inverter has a variable speed compressor that is quiet when running at maximum speed and has a powerful cooling capacity

Eliminate energy waste

Inverter ac compressor
  • The fixed speed compressor only has two speeds-on and off. When the compressor is on, it runs at 100% speed until it reaches the set temperature, then it switches off. When the room temperature rises above the set temperature, it switches on again, then off, on and off, on and off……
  • Rather than expending energy by starting and stopping, the inverter compressor adjusts the speed to be either higher or lower, so that it runs continuously and more efficiency.

How an Inverter Air Conditioner Helps You?

Energy Saving

The Inverter air conditioner can help you save energy bills because it runs at a variable speed. When the room temperature reaches, it will run at a low speed to keep the temperature, so the energy is saved.

Fast Cooling

When it powers on, the variable speed compressor of the Inverter air conditioner will run at a max speed to bring down the temperature quickly. It also improves the comfort.

High Comfort

When the room temperature reaches, the inverter compressor will run at a low speed, keeping the room temperature relatively constant. It like the car runs on the high-speed road, while the normal air conditioner is like the car runs on the city road, always start and stop.

Quiet Start & Operation

The inverter air conditioner uses a variable speed compressor. It raises the speed gradually when it powers on, which is quiet and peaceful. During operation, the Inverter air conditioner adjusts the compressor speed according to different demand of the cooling capacity to keep a quiet operation.

Why people want a 12V RV air conditioner?

Almost all of the caravans, motor homes are equipped with a 220V or 115V air conditioner which needs the shore power. Without the shore power, it needs a generator or an inverter if running on batteries. Generator is a convenient backup option, but it is very noisy, especially in the midnight. You also can use an inverter to turn the 12V DC power from your RV into 120V AC power to run the air conditioner; but it will waste a lot of power.

A new trend in RV air conditioner is 12V DC air conditioner. It is the new solution. The 12V DC air conditioner uses the 12V dc compressor, which is powered by 12V batteries directly. It no needs the generator or inverter, which is quieter and more efficient.

Advantages of 12V RV air conditioner

The largest advantage of 12V RV air conditioner is it could more efficiently run off the battery or solar power, which no needs any inverter to avoid the power loss. The 12V rotary dc compressor not only improves the efficiency of 12V air conditioner, but also ensures the high reliability.

Disadvantages of 12V RV air conditioner

The disadvantage of 12V air conditioner is its high current. For an air conditioner operating on 12V, the wires will need to be larger and the electronics need to handle higher currents. So there is also customers use 48V compressor, which the current is smaller than 12V DC compressor.

The largest cooling capacity and highest efficiency 12 volt dc compressor. If you are looking for a large cooling capacity 12v dc air conditioner compressor, the model JFSB150Z12 is the best choice.
