Welcome to the world of RV living, where you can embrace the freedom of the open road while still enjoying the comforts of home. One of the essential components of any RV is the air conditioner, which keeps you cool and comfortable during those hot summer days. However, running an air conditioner in an RV can sometimes put a strain on the electrical system, leading to potential issues such as tripped breakers or even the risk of damage to the AC unit.

That’s where a soft start for an RV air conditioner comes in. This innovative device helps to reduce the initial power surge when the air conditioner is turned on, ensuring a smoother start-up and minimizing the strain on the electrical system. In this article, we will explore what a soft start is, how it works, and the benefits of using one in your RV.

How Does an RV Air Conditioner Work?

Before diving into the details of a soft start for an RV air conditioner, let’s first understand how an RV air conditioner works. An RV air conditioner operates on the same basic principles as a traditional air conditioning system found in residential or commercial buildings, but with a few key differences to accommodate the unique needs of an RV.

An RV air conditioner consists of two main components: the indoor unit (also known as the evaporator) and the outdoor unit (also known as the condenser). The indoor unit is typically located on the ceiling inside the RV, while the outdoor unit is mounted on the roof.

The air conditioning process begins with the compressor, which is located in the outdoor unit. The compressor pressurizes the refrigerant, causing it to become hot. The now hot refrigerant is then circulated to the condenser, where it releases the heat to the outside air, effectively cooling down the refrigerant.

Once the refrigerant is cooled down, it flows into the evaporator unit, located inside the RV. At the evaporator, the refrigerant passes through a series of coils and fins. As warm air from inside the RV is blown over these coils, the heat from the air is absorbed by the refrigerant, making the air colder. The cooled air is then blown back into the RV, providing a comfortable indoor temperature.

As part of the air conditioning process, the air conditioner also dehumidifies the air inside the RV. As warm air passes over the evaporator coils, the moisture in the air condenses and is collected in a drain pan. This helps to reduce the humidity levels inside the RV, creating a more pleasant living environment.

Overall, an RV air conditioner operates on a simple yet effective principle of removing heat from the indoor air and releasing it outside. With the basic understanding of how an RV air conditioner works, we can now delve into the concept of a soft start and its significance in enhancing the performance of the air conditioner.

What Is a Soft Start?

A soft start is a device designed to reduce the electrical surge that occurs when an RV air conditioner is powered on. When you turn on your RV air conditioner, it requires a significant amount of power to start the compressor and the fan motor. This initial surge of electrical current, known as the inrush current, can put a strain on the electrical system and cause voltage fluctuations. This strain can potentially trip breakers, cause lights to dim, or even damage the AC unit.

A soft start device helps to mitigate these issues by gradually ramping up the power to the air conditioner when it is turned on. Instead of a sudden surge of electricity, the soft start gradually increases the voltage supplied to the compressor and fan motor over a short period of time. This gradual increase allows the components to start up smoothly and reduces the strain on the electrical system.

Soft start devices use advanced electronics and circuitry to control the power supplied to the air conditioner. They monitor the voltage and current and adjust the power output accordingly. By reducing the inrush current, a soft start helps to prevent voltage drops and ensures a smoother start-up, extending the lifespan of the air conditioner and minimizing the risk of electrical problems.

It’s important to note that a soft start does not affect the overall cooling capacity of the air conditioner. It simply helps to improve the efficiency and performance of the air conditioner by providing a more stable power supply.

Soft start devices are typically installed between the RV’s electrical system and the air conditioner. They can be retrofitted to existing RV air conditioning units or incorporated into new units during the manufacturing process.

• Did you know? Soft start devices are also commonly used in other applications, such as large industrial motors and generators, to reduce electrical surges and improve energy efficiency.
