To the Western Cooling Connection Update Newsletter! This issue of the Cooling Connection focuses on three, brief project updates including Aerosol Envelope Sealing, HVAC Behavioral Research, and the Optimization of Hybrid Evaporative/DX Cooling Equipment.
Aerosol Envelope Sealing:
WCEC just completed its 6th demonstration of aerosol-based automated envelope sealing technology in a 2-bedroom apartment in Davis. This demonstration’s goal was to test the efficacy of this technology in an even earlier building stage than previous demonstrations to see how the aerosol particles react to an even leakier environment. The apartment’s build stage is at a pre-drywall phase.
The apartment’s effective leaks were sealed by over 60% in just under 2 hours. This is the most effective sealing demonstration for this technology to date, and it shows versatility. Being able to seal at many different phases of construction can be beneficial to builders who have many projects at various stages and will increase the likelihood that this technology will be more widespread.
Concurrently, WCEC’s box-testing is also underway. The box is used to test different sealant mixtures by controlling these main variables: speed at which the sealant dries, how tacky it is, and how quickly it seals. Another important use for the box is to test other injector nozzles and pressures to determine the effect particle size plays in sealing effectiveness while reducing clean-up time.
HVAC Behavioral Research Update:
We are continuing progress on the roadmap document that will better prioritize research questions for HVAC social human factors. These questions will probe beyond the typical residential/commercial end user to more broadly represent all of the actors involved in HVAC energy efficiency. These actors include:
» Residential end users
» Commercial end users
» Facilities technicians and managers
» Sales Engineers
» Trainers and Certifiers
This roadmap will be completed in August and will be published in the Western Cooling Connection shortly thereafter.
Optimization of Hybrid Evaporative/DX Cooling Equipment:
The goal of the project is dedicated to creating a successful protocol to model indirect evaporative coolers (IDEC). At this stage, the IDEC project is completing fluid testing over a base-case, smooth material to determine the effect of pin geometry and spacing will have on the pressure drop over the heat exchanger.
