3.10 ADVANCED FEATURES DeskTop Air includes special tools that facilitate the calculation of some common air processes. These tools include an expansion/compression tool and a heating/cooling tool. 3.10.1 Expansion/Compression Tool The Expansion/Compression tool is used to evaluate performance of an ...
The calculation of the integral factor Fint of the impurities concentration from the air into the extract is carried by the formula: Fint=FwcondFextr, where Fint is the integral factor of the impurities concentration from air to the extract, Fwcond - the factor of concentration from the air ...
Heat transfer coefficients are temperature dependent; they must be set to perform the calculation on the designated FPSAH of specified properties (Table 1). The determination of these thermal coefficients is achieved by computing the equation system (Eq. (4)) below.(4){keq,g1−g2Tg1−(hw...

Need to correct your cost per operating hour calculation to note the $0.25/kwh needs to be divided by 1,000 to get the watt hour cost. Reply: Thanks so much, Paul. Question: How Can I Reduce the Operating Cost and Energy Consumption of my Air Conditioning & Heat Pump System? As we ...
In my opinion SEER ratings apply to specific pieces of equipment. You don't add, average or mulitply the ratings of multiple pieces of equipment. Such a calculation, to be valid, would be a bit more complex, involving equipment usage. ...
(Condensation) - For this case the calculation is identical to the case for No Connecting Pipe except that the emission rate calculation formula is: m = A ρ* 1.70 ∆H 1+ 4f L d (2-33) Unchoked Flow - If the flow is not choked, the formation of liquid droplets still needs ...
The calculation process is shown in Formula (5), and the results are shown in Figure 2. As can be seen from Figure 2, there is a strong correlation between dry bulb temperature and wet bulb temperature, a weak correlation between dry bulb temperature and wind speed, and a very weak ...
Table 3. Calculation formula of the fuel exergy, product exergy, and exergy destruction of each component in the CO2 heat pump system and of the system. 4. Results and Discussion 4.1. Exergy Destruction and Exergy Efficiency of the System and Each Component In this section, the exergy destru...
DP can achieve the optimal global solution; however, sometimes a large amount of calculation leads to dimensional disaster. Liu et al. [11] used the DP method to determine the best torque distribution scheme for the whole driving cycle in the form of segmented decision making. The PMP method...
