Federal Technology Alert ambient temperature can be a major factor in the performance when no attempt is made to adjust the inlet air temperature (i.e., air cooling to maintain a constant or lowered inlet air tempera ture during extremely hot weather). Higher ambient turbine inlet air temperatures result in lower MTG efficiency, higher exhaust temperatures, higher exhaust heat available for recovery, and higher heat input to the ABSC unit, resulting in better ABSC unit and IES performance. The following sections present the results from tests performed to quantify the effect of ambient air temperature on ABSC unit capacity, COP, and IES efficiency. An MTG power output setting of 20 kW was selected for this series of tests. This power setting was achievable over the entire wide range of ambient temperatures experienced during the tests, 17.2 to 30oC (63 to 86oF). The hot water flow rate from the HRU and cooling water flow rate from the cooling tower were 0.15 m3/min (39.8 gpm) and 0.28 m3/min (74 gpm), respectively. Results will be presented for evaporator chilled water flow rates of 0.07 and 0.13 m3/min (19 and 34 gpm). 5.3.1 Effect of Ambient Temperature on Absorption Chiller Capacity and COP6 The heat input required to drive the ABSC at the full rated load of 35 kW (120,000 Btu/h) of cooling is ~50 kW (172,000 Btu/h). During testing, the maximum heating capacity produced by the MTG + HRU, due to the design features of the HRU and MTG output power setting of 20 kW, was only ~37.9 Fig. 15.

Therefore, at a constant MTG power output setting of 20 kW, the ABSC unit could only be driven to ~82% of its full rated load. The effect of ambient temperature on the ABSC cooling capacity (Qchw) is shown in Fig. 17 for the two chilled- water flow rates (G ) that were tested. chw .PDF Image | Summary of Results from Testing a 30-kW-Microturbine and Combined Heat and Power (CHP) System
