Wherein, meteorologic parameter is mainly from two aspects: first is that each department gas provided from national authority meteorological department
As parameter, the meteorologic parameter of this part is region general character meteorological data for air-conditioning individual；Second is that air-conditioning themselves capture
Individual meteorologic parameter, the meteorologic parameter of this part is individual character meteorological data for air-conditioning individual, can be indirect
Reflect the project installation environment of air-conditioning individual, such as: ventilation, heat dissipation, outdoor, air-conditioned room.Region general character meteorological data and individual
Characteristic meteorological data combines, and can accurately reflect the running environment of each air-conditioning.It is worth noting that if region general character gas
When image data influences big to air-conditioning, the operating parameter of air-conditioning is adjusted according to region general character meteorological data, if individual character
When meteorological data is affected to air-conditioning, it is adjusted according to operating parameter of the individual character meteorological data to air-conditioning.
It should be noted that dew-point temperature TDewBe according in meteorologic parameter temperature information and humidity information be calculated
's.Detailed process is as follows:
Firstly, calculating saturated moist air partial pressure, (gas phase and liquid phase that confined condition is lauched reach the water under equilibrium state
Steam pressure, the pressure value are related with corresponding temperature).
As the outdoor environment temperature T of air-conditioning regionOutsideAt=- 100~0 DEG C, enable: T=273.15+TOutside, it is saturated wet sky
Gas partial pressure pqbIt can be obtained by following formula:
Wherein, c1~c7Value can are as follows: c1=-5674.5359, c2=6.392547, c3=0.9677843 × 10-2, c4
