We learn how to build a refrigeration system and a refrigerator.

In this theoretical-practical workshop we will learn some basic concepts about refrigeration, how poor air conditioning affects our health or what are the environmental impacts generated by the use of refrigeration systems.

Air conditioning and climate control equipment are some of the most energy consuming appliances in our homes. Therefore, the second part of this workshop will consist of learning in a practical, simple and participatory way to build a low-cost air conditioning system and a homemade refrigerator. In its construction we will use recycled materials and we will verify that they are simple to execute and effective, as they will help us to cool the environment of our homes, reduce our ecological footprint and reduce our electricity costs.

In the first case, we will create an air conditioning system using the phenomenon known as the Venturi Effect by using recycled plastic bottles to generate a simple design that helps lower the temperature by up to 5 degrees. In the second case, we will elaborate a homemade Pot-in-Pot refrigerator that works without electricity. For this we will use the principle of evaporative cooling using completely common materials such as clay pots, sand and water.
