Evaluate the performance of variable speed compressor and supply fan controller for packaged rooftop...

Technology employs evaporative effect, in lieu of electrically-driven refrigerant compression, to chill water for HVAC cooling...

The purpose of this project is to develop a laboratory test method for evaluating FDD technologies on a Commercial Packaged Rooftop...

This is a study of the market barriers that prevent emerging technologies from being adopted by the HVAC market. Its benefit is definition of possible solutions to increase adoption of EE...

The purpose of this project is to perform a laboratory assessment of fault detection and diagnostics technologies (onboard and in-field) on a packaged rooftop unit air...

This system eliminates the central engine room, long piping runs and associated parasitic losses with a traditional ammonia-based system. All components are energy optimized, fully automated, remotely monitored and auto DR ready. This assessment looks at low temperature (-15'F) refrigerated...

Verify the performance of two advanced indirect evaporative technologies as replacements for air-cooled DX cooling. Two field demonstrations will be undertaken to evaluate and validate the technologies. The units will be installed and monitored for a...

Produce chilled water for building cooling without the use of compressorized...

The pool pump system being evaluated is a hybrid AC and solar powered DC system. A DC pool pump is directly fed by PV panels installed on the roof of a building. An automatic digital motor controller changes the torque and speed of the DC motor based on the input power coming from the PV panels....

The Project Purpose is to identify lessons learned while retrofitting residential homes to ZNE levels. Observations in the field during the ZNE retrofit projects will form the basis of this report. The expected outcome of this project is to educate builders, trades people as well as other...
