The Measured Energy Impact of Infiltration Under Dynamic Conditions
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1992-05)
Energy consumption due to air infiltration is customarily assumed to equal the mass flow rate times the specific enthalpy difference between the inside and outside air. Anderlind showed theoretically that this represents ...
Impacts of Optimized Cold & Hot Deck Reset Schedules on Dual Duct VAV Systems - Theory and Model Simulation
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1998)
Optimal hot and cold deck reset schedules
can decrease simultaneous heating and cooling
in VAV AHUs comparing with constant cold
deck temperature operation. In this paper,
optimization models are developed. The energy
impacts ...
Use of EMCS Recorded Data to Identify Potential Savings Due to Improved HVAC Operations & Maintenance (O&M)
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1996)
In most chiller and boiler central plants, the
energy management and control systems (EMCS)
monitor and record key operation parameters and
energy production continuously. A method was
developed to identify potential O&M ...
Reducing Pump Power Consumption by 40% (1000 KW) Through Improved Pump Management in a Central Plant
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1998)
Chilled water system data collection and field
measurements performed at the Central Utility Plant
of Texas A&M University revealed that 30 - 50 % of
the primary pump head is consumed by manual and
automatic valves being ...
Impacts of Static Pressure Set Level on the HVAC Energy Consumption and Indoor Conditions
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1996)
Air static pressure must be maintained at a
certain level leaving the air-handing unit (AHU) to
force a suitable amount of air through the terminal
boxes. However, an excessive static pressure level is
often used due to ( ...
An Advanced Economizer Controller for Dual Duct Air Handling Systems - with a Case Application
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1996)
Heating penalty is expected when economizers
are applied to dual-duct air handling systems.
The heating penalty can even be higher than the
cooling savings when the hot air flow is higher
than the cold air flow. To avoid ...
A Prediction of Energy Savings Resulting from Building Infiltration Control
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1996)
Heat transfer through building walls
consists of three main components:
conduction heat transfer, solar gain and
infiltration heat transfer. An interaction
among these three heat transfer
components alters the effective ...
The Measured Energy Impact of Infiltration in an Outdoor Test Cell
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1992-05)
The energy consumption calculation of house envelopes assumes that conduction heat loss is independent on air infiltration heat loss, and that energy consumption is the sum of these losses. Anderlind [1985], Liu [1987], ...
Rehabilitating A Thermal Storage System Through Commissioning
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1998)
A thermal storage system was installed in a
37,000 ft2 hospital in April 1992. The chiller
had to be operated every summer during peak
demand periods until the authors rehabilitated
system through building commissioning ...
Reducing Building Energy Costs Using Optimized Operation Strategies for Constant Volume Air Handling Systems
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1994)
Building energy consumption can be substantially
reduced after implementing what we call Extended
O&M Measures. The Extended O&M Measures are a
scientific refinement of traditional O&M measures.
Specifically, they ...
