Background
With the global warming and the great development of tourism and economy, air conditioners are installed in many hotels, shops, offices and even common people, which brings joy and cool to people and brings 'air conditioning disease' which is troubling to people. Somebody says that the self has the 'air conditioning disease', and actually misunderstands the 'disease'. "air conditioning disease" refers to the condition reaction of the body caused by long-time air blowing, rather than the disappearance of air conditioning. The prevalence of colds and epidemics is also beginning with air conditioning. Most 'air-conditioning diseases' are caused by too low air outlet temperature and are frequently generated in women, old people and children.
At present, the existing refrigeration direct-blowing prevention and wind-free technologies can solve part of problems, but other problems still exist in the using process. The anti-direct-blowing function is that the air conditioner can blow out the refrigerating airflow upwards at an angle by adjusting the angle of the air deflector, so that people can not be blown. However, this function has two problems: firstly, the cold air has high density and finally falls to the ground, and the user position is just at the place and is blown by the cold air flow, so that discomfort is caused; secondly, the air deflector angle needs to be adjusted to prevent direct blowing, so that the air deflector angle is too small, no air flow passes through the back, and the problem of condensation and water dripping can occur in long-term operation.
In addition, the non-wind feeling is realized by dispersing through the micropores of the guide plate, the air flow distance is shortened, and people are not blown. However, this function has two problems: firstly, the air quantity is seriously attenuated, the temperature of an evaporator is reduced, the pressure ratio of a compressor is increased, and the power consumption is increased; secondly, after the air quantity is attenuated, the indoor cooling effect is deteriorated, and the user experience is deteriorated.
