Use of RV fridge fan

Unlike other refrigerators for home use, RV refrigerators are unique as they use a different cooling mechanism. Furthermore, it’s hard to absorb and cool air even if the weather is too hot or cold.

However, a fridge fan can solve many problems associated with cooling. Typically, it will take RV fridge to cool between 4 to 6 hours, but with a RV refrigerator fan, it can reduce the cooling time to up to 50%.

The air surrounding your RV refrigerator may not be equal to that inside it. Therefore, it may take a lot of power for absorption of warm air.

Fridge vent and evaporator fin fans are the two upgrades every RV should have. Most modern refrigerator do work best but a time comes when you see the operation isn’t that great.

Their ability to cool is dependent on the ability to dissipate the heat. With this approach, the backside of the refrigerator can get very hot. This can eventually reduce their efficiency to cool down.

Normally, the RV refrigerators have vents provided at the bottom of the fridge on the outer side of the RV or on the roof. This helps exhaust the heat away and helps the fridge to cool down.

This vents allow hot air to escape and also provide for cool air to enter. But this operation may not be that great.

To enhance this ability to cool down we can make use of vent fans for fridge.

While selecting the vent fan its always better to go for a smart fan that can automatically turn itself ON when the temperature is on higher side and then turn itself off when the required temperature is met.

Using Evaporator Fins

Using evaporator fins can help circulating the air inside the refrigerator. This will help in keeping the concentration of cool air constant throughout the refrigerators.

As the fridge keeps working, the propane flame absorbs water up to the top of your cooling unit. Now, the fan plays a significant role; the fan will circulate air and ensure hot air can rise to the top where they will be eliminated.

As the warm air, which is less dense, rises to the top, the cold air will get into the refrigerator and balances the temperature, thus ensuring the active cooling system.
