RISVariable Speed Drive Volumetric Tracking for Airflow Control in Variable Air Volume Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An airflow control method has been developed for variable air volume (VAV) systems. This airflow control method is termed VSD volumetric tracking (VSDVT) since both the supply and return airflows ...
LAHU Heat Recovery System Optimal Operation and Control Schedules
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Optimal operation and control of heat recovery in an integrated Laboratory Air Handling Unit (LAHU) system differs substantially from that in conventional dedicated AHUs for laboratory buildings ...
Energy Performance Analysis of Coupled-Control Units With Both Thermostat and Humidistat
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Coupled control units typically condition a single zone with constant air volume. A thermostat controls the heating valve or cooling valve when the room relative humidity is below the set ...
A Noncalorimetric Method for Heat-Transfer Coefficient Measurement of Building Thermal Envelopes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A noncalorimetric method for measuring the heat-transfer coefficient (UA) of building thermal envelopes is proposed and applied in an indoor test cell. The UA value measured by this method ...
The Measured Energy Impact of Infiltration in an Outdoor Test Cell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Air infiltration energy consumption was investigated in an outdoor test cell with different leakage configurations and air flow rates under both infiltration and exfiltration. Measurements showed ...
The Maximum Potential Energy Savings from Optimizing Cold Deck and Hot Deck Reset Schedules for Dual Duct VAV Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the physical models for the maximum potential thermal energy savings from optimizing the hot deck and cold deck reset schedules for dual duct variable air volume systems. ...
Economizer Application in Dual-Duct Air-Handling Units
Publisher: American Society of Civil Engineers
Abstract: Economizers modulate outside air intake to minimize/eliminate mechanical cooling in air-handling units when outside air enthalpy is lower than the return air enthalpy. A theoretical study is conducted to developed analytical ...
Optimal Airflow Control of Laboratory Air Handling Unit (LAHU) Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Laboratory Air Handling Unit (LAHU) system conditions both the office section and the laboratory section. It improves indoor air quality by maximizing outside air intake to the office section ...
Experimental Validation of the Laboratory Air Handling Unit System (LAHU)—Part I: Winter Operation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The laboratory air handling unit (LAHU) system for laboratory buildings has been developed and optimized. Theoretical study has concluded that the LAHU with optimal outside air control and optimal ...
Continuous CommissioningSM of Building Energy Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Continuous Commissioning (CCSM ) is an ongoing process to resolve operating problems, improve comfort, optimize energy use, and identify retrofits for existing commercial and institutional buildings ...
