Description
Technical field
The present invention relates to a kind of field of air conditioning, refer in particular to a kind of air-conditioning and control method thereof.
Background technology
Atmospheric pressure, temperature, humidity are meteorological three large key elements.As shown in Figure 1, it has illustrated the variation relation table of comparisons of atmospheric pressure, temperature and height above sea level, atmospheric pressure and height above sea level, humidity, temperature be varied to inverse ratio; Height above sea level is higher, and air is thinner, and atmospheric pressure is lower; Humidity is larger, and airborne moisture is more, and the combined molecular weight of the molecular weight ratio air of water is little, and the increase of moisture in air equals to have diluted air, and therefore, air pressure is lower; Temperature is higher, although increased the collider meeting of air molecule, air expands rapidly, convection current, and cause that air thins out, and the head-on collision energy that the head-on collision energy of its increase weakens and reduces much smaller than air, natural air pressure reduce, and therefore, air pressure is lower.Atmospheric variation has close relationship with weather.In general, fine atmospheric pressure is higher than the cloudy day, and the atmospheric pressure in winter is higher than the summer.
Excessively low, too high or short time internal gas pressure changes when excessive when air pressure, and is apparent in view to the adverse effect of people's psychology, physiological health.
In environment under low pressure, because rarefaction of air, airborne partial pressure of oxygen also reduces, and causes hemochrome hypoxemia not occurred by oxygen saturation.When the deposit of oxygen in the body be down to basic stock 45% the time, life will be affected.It is generally acknowledged at the 240mm mercury column when (being equivalent to 8500 meters height) to only have under the normal barometric pressure 45% hemochrome and oxygen to be combined into blood oxygen in the human body, therefore claim this air pressure (or height) to be the physical endurance of life.Under the hypobaric hypoxia situation, the lighter's (3000 meters height are following) people can feel mouth and nose xerophthalmia scheorma, dizziness, asthma; That severe one (3000-5000 rice height) people will occur is uncomfortable in chest, be short of breath, n and V, so that remarkable obstacle occurs nervous system.
In anticyclonic environment, human body is respectively organized gradually by nitrification (after generally under high pressure working 5-6 hour, human body is just by nitrification), when human body comes back to standard atmospheric pressure, nitrogen superfluous in the body is just discharged with exhaling, but this process is slower, if get back to suddenly the standard pressure environment from hyperbaric environment, the nitrogen of then accumulating in the fat just may some rest in the human body, and the little bubble of formation that expands, retardance blood and tissue easily form aeroembolism and cause illness, severe patient entail dangers to people's life.
Simultaneously, the psychology that air pressure also can affect human body changes, and mainly is to make the people produce oppressive mood.For example, the hot and humid weather before the sleety weather under the low pressure, the especially thunderstorm in summer (this moment, air pressure was lower), cardio-pulmonary function bad people can feel bad unusually, and the normal person also has a kind of sense of depressed discomfort.And thisly feel suffocated and constrain, can make again people's vegetative nerve trend nervous.
The air-conditioning of prior art mainly is to regulate the temperature of air-conditioning according to self use habit of people, and does not consider the atmospheric pressure factor to the impact of environment, comprises that existing comfort level interval is also just according to the temperature of the variation adjusting air-conditioning of temperature and humidity.
