How Does a Pool Chiller Work?

If you live in a hot or humid climate, you might be looking to make your pool time a little more crisp and refreshing. Pool chillers are your answer.

Let's break it down into 5 simple steps.

You probably already have air conditioning in your house. A pool chiller works like A/C, but instead of cooling air, it cools water.

Step 1: The liquid refrigerant absorbs heat from circulating pool water.

The pool chiller pumps the heated refrigerant to the compressor, and then...

Step 2: The compressor applies pressure to turn liquid refrigerant into a gas.

This phase change from liquid to gas pushes the refrigerant to...

Step 3: The refrigerant moves to the condenser coil outside the unit, releasing the heat it absorbed.

As it cools, the refrigerant changes back into a liquid, and it flows into...

Step 4: The expansion tube reduces the pressure on the refrigerant liquid, allowing it to rapidly cool even more.

The refrigerant is super cold again, and it finally moves back to...

Step 5: The refrigerant flows into the evaporator coil, which is submerged in the pool water, and it absorbs heat from the water.

And the pool chilling cycle restarts!
