The condensate measurement was used as a method for latent capacity evaluation, because at higher ambient conditions the difference in dew-point temperature
between the inlet and outlet of the indoor unit was small, resulting in significant uncertainty.
I supplement my dew shield with active dew-busting tools that warm the optics until they are above the dew-point temperature
The total uncertainty in the dew-point temperature
measurement was approximately [+ or -] 0.
This finding is explained by the fact that lower moisture content in the air reduces the dew-point temperature
in the exhaust air side, and thus a lower surface temperature is required to produce condensation and frosting.
As seen, the temperature of the refrigerant from the first-stage expansion caused by the capillary tube is designated to be above the corresponding dew-point temperature
of the ambient environment.
It was also mentioned that the dew-point temperature
of CFB boiler flue gas should be determined.
Although it is not yet a guideline, a preliminary report to ASHRAE's Technical Activities Committee from the MTG suggests that a 60[degrees]F (16[degrees]C) dew-point temperature
can be used as a "prudent upper limit" that describes the normal behavior of well-designed and maintained mechanically cooled buildings in any climate during the cooling season.
Trends for average dew-point temperature
(Figure 4[a]) are significantly different from those for dry-bulb temperature.
The refrigerant mass flow produced by the compressor increases with increasing suction dew-point temperature
and decreasing discharge dew-point temperature
The properties determined include bubble-and dew-point temperatures
, vapor pressure, equilibrium composition of the components, enthalpy, and entropy of the mixtures at saturation pressures.
If the temperature of the evaporator wall becomes lower than the dew-point temperature
of air, then condensation of moisture in air takes place.
The rate of increase in the cooling duty during the initial cooling cycle was found to be much larger for the air condition with a higher air-side dew-point temperature
