1 [ASHRAE 2004b]) and knowing that the supply flow rate is already determined considering the building cooling load
(not a variable in Equations 5 and 6), the coil cooling load is a function of ERV sensible and latent effectiveness.
The peak-shifting controller must find the time-shifted cooling load trajectory that minimizes input energy, given a building cooling load
trajectory and the performance characteristics of a chiller and associated mechanical (transport) equipment.
The differences in these methods lie mainly in how the instantaneous building cooling load
is measured (Honeywell 1997).
The net result of the envelope upgrades included in the renovation reduced the overall building cooling load
by 457 kW (130 tons) when compared to the ASHRAE 90.
In general, the chiller load at any time interval is the sum of the building cooling load
and the storage charging rate (negative for discharging) or
Measuring the fresh-air volumetric flow rate for each terminal is very time-consuming; however, the total fresh-air volumetric flow rate can be easily estimated according to the relationship between daily average outdoor air enthalpy and building cooling load
Typical building cooling load
profiles and ambient wet-bulb temperature profiles for a hot day and a mild day in Philadelphia were determined from TMY climatic data (NREL 1995), as shown in Figures 2 and 3.
The plant plus the air side equipment, defined here as the central chilled water system (CCWS), is the equipment required to transfer the building cooling load
to the atmosphere.
Also discussed previously is the issue of loss of cooling capability that could occur due to uncertainty in the building cooling load
The small--size, single--sheet scanners consume less than 20 W and do not contribute significantly to the building cooling load
In order to maintain high utilization, the solar cooling system should generally be sized only for the solar component of the building cooling load
It is generally discharged during occupied period as needed to meet the building cooling load
