Overview of Status of Analysis, Design, Fabrication, Tests, etc.
The HOBOLink network is up and running. We have an account setup and are ready to collect data. (Team effort)
The work order for the electrician has been submitted and processed. (Cara)
The main construction for the plumbing has been done. There is a drain and there is a connection to the water line. As soon as the plumber is done, (by Thursday) we can start running tests to calculate the COP of the heap pump, and the EF of the system.
The entire setup is not done yet because the heating element on the hot water tank still needs to be hooked up by an electrician. (240V).
Accomplishments from Previous Week
Setup an account with HOBOLink and have a system for data acquisition setup. (Nadim, Cara, Xavier)
Finished creating a CAD of how the setup would fit in the first test area that was 0.6223m x 0.6731m (24.5" x 26.5"). (Sean, Xavier)
Have a basis for the simulation setup in Labview. (Chris, Xavier)
Finished the first draft of the report. (Team effort)
Finished the proof of concept presentation for this week. (Chris, Sean, Nadim)
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Start running tests and calculate the COP and EF of the system to see how much extra energy (if any) is needed to heat the water to the desired temperature. (Team effort)
To have the whole setup finished. (Have the electrical parts hooked up to the top element of the hot water tank and the heat pump)
Finish the simulation for COP and EF of the system. (Xavier, Chris, Nadim)
Continue updating website. (Mainly Sean, but everyone else as well)
Keep on adding to the final report when few tests are ran. (Group Effort)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments
The sponsor mentioned that the temperature of the hot tank should be at 57C (135 F) to start the test to kill the bacteria and then start to fluctuate the temperature from there.
The sponsor has brought an anti-scalp valve to mix the hot and cold temperature from the cold tank (if necessary) and also he brought a flash heater to be used (if necessary).
Instructor Comments from Last Meeting and Actions Taken to Address these Comments
Thermos-wells could be used for installing the sensors, but decided to use a male-female tee pipe and reducers.
The power input to the system needs to be measured. Transducers will be used. (Cara)
Risks and Areas of Concern
The simulation made on the LabVIEW shows there is not enough energy to heat the water to the desired temperature which means at least one of the electrical elements has to be connected and running to help the process.
Resources or Information Required but not Available
How much energy does the heat pump use? How would it affect the efficiency of the system when the temperature of the cold tank goes down?
Schedule
Running the tests by early next week to calculate the COP of the heat pump and EF of the system.
Budget (list amount spent and amount remaining)
Progress on Report and Webpage
Finished the first draft of the report.
The proof of concept presentation updated to the website. (Sean)
