A bin temperature method was used to estimate annual energy savings, which include sperate calculations for heating energy, cooling energy, AHU supply fan energy and return fan energy.
For each of the two DOAS, time stamped data points were collected every 5 minutes (or as events occurred with certain operating parameters) and summarized hourly for the readings from: pulse counter equipped gas submeter for the DOAS gas usage; current switches on the gas valves to record 4 stage operation (two on each heating module with 2 stage gas valve); supply fan kWh meter; flue temperatures (two per DOAS--one for each heating module); supply air temperature; and ambient temperature.
There are three inputs to the AHU: (1) hot water valve for the heating coil/zones, (2) supply fan speed, and (3) fresh air from outdoors.
Table 1 is an example from a recent TAB report that had two plenum supply fans installed in parallel to illustrate the verification of field measured values.
HRW-1800-MS-270 reduces the annual energy consumption of supply fans by 18%.
* The ASHP system performs better than the split DX system for all cases except when the supply fan cycles together with the heating or cooling coil load in extremely cold climate conditions.
Reduction in supply fan horsepower due to lower ductwork pressures.
The motor on a supply fan was the root cause of Monday's power outage at the Lane County Courthouse, a system assessment revealed.
"We are proud to be chosen by Freightliner as their partner to supply fan drives and fans," explains Keith Pierson, Director, Global Sales, BorgWarner Thermal Systems.
To achieve these quiet acoustic levels, the chassis' fan control technology is said to optimize the speeds of both the chassis system fans and the power supply fan. This chassis, with an operating temperature range from 0[degrees]C to 40[degrees]C, is suited for temperature-controlled environments requiring low acoustic noise.
