The cooling capacities reported were calculated from the measured chilled water flow rate and the difference between the entering and leaving chilled water enthalpies.
This increase in supply water temperature would require double the design chilled water flow rate to meet the same cooling load condition.
Through chilled water flow control, the water saving effect can be enhanced.
In contrast to the variable chilled water flow rate, which results in wide range of evaporator effectiveness, the condenser water flow rate is almost constant resulting in a narrow range of condenser effectiveness.
This allowed the effect of changes in chiller water return temperature and chilled water flow rate to be ignored in determining the optimal supply air and chilled water temperatures set-points.
We used to ask about marketing trends: "Which way does the wind blow?" For those seeking to market USA-produced poultry into England or Europe the question might now be: "Which way does the chilled water flow?"
Further analysis of heat transfer impacts (4) showed that coil UVGI resulted in a chilled water temperature difference increase of 0.4[degrees]C to 0.6[degrees]C (0.7[degrees]F to 1[degrees]F) and a corresponding decrease in chilled water flow rate of 8.0% to 11.9%.
One of the innovative construction techniques used on the project was the chilled water flow for each tenant that was monitored and controlled based on the delta T returned from each tenancy utilising pressure independent control valves (PICV).
Part-load efficiencies are lower and vary based on several parameters such as supply and return chilled water temperatures entering condenser water temperature and condenser and chilled water flow rates.
The cooling capacities reported were computed from the measured chilled water flow rate and the difference between the entering and leaving chilled water enthalpies.
The second set consisted of a load line with the chilled water flow rate adjusted to 2.4 gpm/ton (2.6 L/min kW) and the cooling water flow adjusted to 3.0 gpm/ton (3.2 L/min-kW) at full capacity per AHRI Standard 550/590-2011 (ANSI/ASHRAE, 2011).
