Can Dyson's heating and cooling replace air conditioning? Which model of Dyson fan is better?

First, if the room is more than ten square meters, it will still have obvious effects, but it will be greatly weakened if it is bigger. Air conditioning system has stronger thermal refrigeration effect, especially refrigeration effect. Dyson fan can only be used in the environment where the temperature is not too high, because the wind blown out after the ambient temperature is high is still hot and makes people feel cold; Air-conditioner can refrigerate in most environments and realize constant temperature function.

Secondly, under the first-class industrial design of Dyson, the high reliability of Dyson bladeless fan has been created. The motor passed 38,000 hours of continuous use test, and the switch button passed 36,500 times of pressing test. Dyson's bladeless fan won awards including 20 10 Red Dot Award, iF Award and Good Design Award. Having said that, can Dyson's cooling and heating replace air conditioning? There is still a difference between the two. Although Dyson can cool and heat, its main principle is close to that of a fan, which can be regarded as an extension of a bladeless fan. Refrigeration generally relies on strong wind circulation to lower the room temperature. When the wind blows to the surface of human body, the water on the surface of human body evaporates and absorbs heat, which makes human body feel cool, but the cooling range is limited, just a few degrees.

Third, the heating is done by an electric porcelain ceramic heater, which is similar to a heater. Air-conditioning transfers indoor heat to the outside through the "transport" function of refrigerant, which reduces the indoor temperature of the human body's environment. The heat has been transferred to the outside, and the room becomes cold, and the human body will feel cold. In addition, the heating function is only reversing. The air conditioner can heat by controlling the four-way solenoid valve installed in the external machine to reverse the condenser and evaporator. The other air conditioner is equipped with an electric auxiliary heater. Simply comparing the two, Dyson's heating and cooling is relatively limited by space.

Four, in addition to the unique bladeless and air amplifier airflow multiplication technology, thanks to Helmholtz cavity silencing technology, it is more silent, and has passed the Quiet Mark mute certification in the UK. Not to mention that some air conditioners also have heating and dehumidification functions. So strictly speaking, it is ok in some special circumstances, but it is not possible in most occasions.
