economize

vb. to produce:
  1. a given OUTPUT of a product using fewer FACTOR INPUTS than previously;
  2. more output than before from the same amount of factor inputs;
  3. a given output of a product at lower cost than before by substituting cheaper factor inputs for more expensive ones in the production process (the ‘ideal’ or optimum position is attained when the largest possible output is produced from a given volume of factor inputs using available technology);
  4. a given output at the least possible factor cost. See PRODUCTIVITY, EFFICIENCY, ECONOMICS, PRODUCTION POSSIBILITY BOUNDARY.

The lowest energy use shown happened on November 16, when the economizer operation occurred for all but about 15 minutes.
HX-2 is the new 1,000 ton (3520 kW) plate-and-frame waterside economizer heat exchanger, with its capacity chosen to provide the winter cooling load, essentially equaling the capacity of any two of the 500 ton (1760 kW) chillers.
Usually the performance of refrigerating system with economizer can be predicted and parameters of required components can be determined using the selection software provided by compressors manufacturer.
To test whether the approach is cost effective, analysis of an evaporative closed-circuit pre-cooler for return chilled water is applied to loads for a cooling system without outside air economizers. Analyzing this system provided the best indication of the cost effectiveness of a water economizer approach, as it clearly showed the savings from adding a discrete water economizer that was sized to match full cooling load without a chiller at 50[degrees]F DB and 45[degrees]F WB (10[degrees]C DB and 7[degrees]C WB) outside air conditions, matching the ASHRAE Standard 90.1 water economizer sizing requirements.
The Hitec Economizer has already proved its effectiveness.
where [X.sub.v] is the mole fraction of refrigerant that evaporates as it throttles to the economizer unit.
This White paper provides a unique insight into operating Cooling modules in economizer mode in a manner that doesn't compromise on efficiency or availability.
The prefab elements of the heat economizer are identical plane panels of compact concrete, with high mark, with rectangular form, with thickness of 50 mm, in which one parallel pipes ensemble of 13.5 x 2.25 mm is involved through which water moves in stages by cross flow, joined in backwash in bearing by movement of gases through free spaces between neighboring panels, spaces with breadth of 15 mm.
According to Ots [3] the proportions of the different ash fractions in an averaged ash flow are: 39.3% bottom-slag ash, 3.1% superheater ash, 4.7% economizer ash, 32.2% cyclone ash and 13.5, 3.1, 0.7% of ash from electrostatic precipitators 1, 2 and 3, respectively.
This reference volume contains ASHRAE standards and recommendations for environmental criteria, mechanical equipment, economizer cycles, airflow distribution, total cost of ownership and emerging technologies.
Bomag has integrated its Economizer system into the compactor for soil compaction status.
Economizer systems typically use mixed-air temperature (MAT) measurements for feedback control of the outdoor and return-air dampers.
