How does the Dyson fan heater work?

How Dyson Heater and Cooling Works

The Dyson hot + cold fan heater is a space heater that utilizes airflow technology, known as air Multiplier technology, to provide a stream of hot or cold air. The heater draws air in through the use of an impeller, which then passes through the ramp, and low pressure is created due to the Bernoulli principle. This results in inducing the air behind the fan which then causes the surrounding air to follow the air flow. The air flow generated by this is greatly amplified as compared to the initial air flow and it is approximately about fifteen times stronger than the initial air flow.

The shape of the Dyson space heater is can be cylindrical or round and it does not contain any fan blades or exposed heating coils which makes it a very safe choice for anyone with kids or pets. This is thanks to the air multiplier technology that is used to carry the hot or cold air around the room.

Similar to this the technology used in generating the heat is also very innovative. The Dyson space heater utilizes positive temperature coefficient (PTC) ceramic plates to provide heat. The PTC ceramic plates heat up as electrical energy is provided to them and they are strong conductors of heat. This is a similar function that is used is most ceramic heaters. However, Dyson effectively utilizes this technology along with the air multiplier technology to provide efficient and effective heating.

The Dyson space heater also uses technology that is similar to jet engine coolers, this allows the ceramic plates that are located within the loop airflow amplifier to not only heat the air flow but to also generate a small flow of cool air. The cool air flows between the ceramic plates and the thermoplastic of the heater, which acts as a buffer in order to ensure that the surface of the fan heater remains cool to the touch.  The ceramic plates used are self-regulating and reach a maximum temperature of 200 degrees Celsius or roughly 392 degrees Fahrenheit.
