Finally, trends for average wet-bulb temperature (Figure 5[a]) present an interesting combination of the features of both Figures 3 and 4 (which is not too surprising since, from a mathematical point of view, wet-bulb temperature is between dew-point temperature
and dry-bulb temperature).
The total uncertainty in the dew-point temperature
measurement was approximately [+ or -] 0.
The temperature is designated to be above the corresponding dew-point temperature
of the ambient environment after first-stage expansion to eliminate the condensate problem.
In this particular case it is possible that the temperature of the APH tube falls below the dew-point temperature
of flue-gas water steam, and water steam from flue gas condensates on the tubes.
The test data recorded and analyzed indicates that the increased air dew-point temperature
results in a greater frost mass deposit rate and an increase in frost thickness.

The 12 selected typical months for each station were chosen using statistics determined by considering five elements: global horizontal radiation, direct normal radiation, dry-bulb temperature, dew-point temperature
, and wind speed.
If the temperature of the evaporator wall becomes lower than the dew-point temperature
of air, then condensation of moisture in air takes place.
With the patented concept in mind, the next step, proposed by the inventor, is to make each of the above stages more efficient with the result that the supply air could approach dew-point temperature
The bold, solid line indicates the dew-point temperature
of indoor air at 22[degrees]C over a range of relative humidity values.
As such any start-up regiment for an ACB system must involve an early drying-out of building air by the early and separate operation of the DOA system, with chilled water going to ACB terminals only after space dew-point temperatures
have been lowered below ACB terminal temperatures.
Per ANSI/ARI Standard 1200-2006, the adjusted dew-point temperature
was determined as the saturated temperature of the refrigerant at the evaporator pressure minus 2[degrees]F (1.
