Guide to Safely Using Dry Ice in Air Conditioner Fans

Specialized gel dry ice used in air conditioner fans is composed of water and gel, forming a naturally cohesive and flexible mixture. Subsequently, this mixture is solidified to create gel dry ice with a temperature ranging from 5 to 10 degrees Celsius, providing longer cooling capability than regular ice.

Varieties of air conditioner fans on the current market utilize two primary types of dry ice: dry ice in plastic bags and in plastic boxes.

Dry ice in plastic bags is a compound inside that helps retain water, freeze quickly, and thaw slower than regular ice. This type of dry ice is tightly wrapped in a durable PE plastic bag.

Dry ice in plastic boxes also contains a solution to help retain water, freeze quickly, and thaw slower than regular ice. However, in addition to the PE plastic bag layer, this type of dry ice is also encased in a very sturdy plastic box.

Dry ice in plastic boxes is securely wrapped to ensure user safety.

If you know how to use dry ice, your air conditioner fan will cool more effectively. Typically, manufacturers include 1-2 boxes of dry ice when you purchase an air conditioner fan. If not included, you can buy a separate box at a price of just a few tens of thousands.

Next, use dry ice for the air conditioner fan with the following steps:

Step 1: First, place the dry ice in the freezer compartment for about 2 - 3 hours beforehand to solidify when used in the air conditioner fan.

Step 2: Take the solidified dry ice and place it in the ice compartment of the air conditioner fan. Once you notice the gradual decrease in cold air, remove the dry ice and place it in the freezer compartment for 2 - 3 hours before reusing it as usual.

To maintain flexible adjustments and uninterrupted cooling, manufacturers recommend users prepare 2 boxes of dry ice for each air conditioner fan.

Prepare at least 2 boxes of dry ice to ensure uninterrupted cooling process of the air conditioner fan.

With the aforementioned steps on using dry ice for air conditioner fans, you might wonder about its cooling duration. In reality, the cooling time of dry ice depends on the quality and size of each box, as well as the operational capacity of the air conditioner fan. Typically, each type of dry ice will have different cooling durations for the air conditioner fan, specifically:

      + For dry ice in plastic bags: Thawing time is approximately 3 - 6 hours in a water environment and the shelf life is 15 - 20 times (if the bag layer is torn, it should not be used anymore).

      + For dry ice in plastic boxes: Thawing time is longer than in bags, averaging between 5 - 8 hours in a water environment. The shelf life of dry ice in plastic boxes is about 45 - 50 times, higher than in bags due to the durable hard shell allowing for multiple reuses.

To ensure safety during the use of dry ice, users should consider the following issues:

      + Although it has been inspected and guaranteed to be absolutely safe, incidents may occur during the use of dry ice. Therefore, users should not eat and keep dry ice out of the reach of children.

      + Avoid direct contact with dry ice as it can cause frostbite due to its very low temperature.

      + Do not store dry ice in a sealed container as it can cause explosions due to the sublimation process producing CO2 gas.

      + Avoid strong impacts on the dry ice box shell to prevent cracking or breaking.

      + If dry ice is cracked, it should not be continued to be used, as the gel part can be dangerous and affect the lifespan of the air conditioner fan.

      + Choose the appropriate quantity and size of ice bags for the type of air conditioner fan being used instead of excessively relying on dry ice for cooling purposes.

You should select dry ice with suitable size and quantity for the type of air conditioner fan being used.

In addition to instructions for using dry ice for air conditioner fans, users may also have some common questions that need answers like:

Users can rest assured when using dry ice, as this type of ice has been meticulously quality tested. Additionally, to ensure safety, manufacturers also tightly wrap it in a layer of plastic bag or box outside the liquid mixture. However, since dry ice has a quite low temperature, users should not eat or drink dry ice and especially keep it out of reach of young children.

Depending on the type, size, and manufacturer, the price of a box of dry ice for air conditioning ranges from 40,000 to 100,000 VND.

The price of dry ice on the current market is ranging from 40,000 to 100,000 VND.

It can be said that combining dry ice with an air conditioner fan helps create a cool breeze and brings a comfortable feeling to users. Hopefully, through this article, you have grasped the instructions on how to use dry ice in an air conditioner fan, in order to maximize the effectiveness of this type of ice!
