Thermofusion is a technique that consists of a simple and fast welding with which the union of polyethylene pipes, also known as PPR, and their corresponding accessories is made. For this it is necessary to use a machine called a thermofuser, which can reach up to 270ºC in temperature.

How does the thermal switch work?                                   Irons have a thermostat that keeps the temperature between two limits: one low the other high.  This makes the resistance turn on and off. So there is a heat exchange, since heat is transferred between two media,separated through a barrier or in direct contact. The device is cooled by the current of air that flows over it and, in turn, this reduces the temperature. By receiving the heat energy from the plug, it tends to heat up until it reaches a point where it does not receive any more heat.

The compressor is located outside, it compresses the gas, hot air enters in the circuit goes to the evaporator and gives up its heat to the refrigerant gas, cooling the room, then the condenser absorbs the heat of the refrigerant gas and expels it To the exterior. This simple refrigeration cycle is the fundamental engineering principle that governs all air conditioning systems

The Playstation has a built-in air cooling system, which gives it the ability to run for quite some time without any failure of the systems. This is based on air circulation as a method of dissipating heat.
