Overview of Status of Analysis, Design, Fabrication, Tests, etc.
The transducers have arrived and been installed. (Cara, Chris)
Finished first set of testing and beginning second set. (Everyone)
Test with constant cold water temperatures of 11°C, 13°C, 15°C
Test with constant flow rate ratios of 3.5:1 and 4:1 cold to hot water
Currently working on a new Solidworks model for overall system for report. Almost done (Cara)
Accomplishments from Previous Week
Finished testing for the first set of tests. See above testing prompts. (Everyone)
Calculated and graphed the COPs for the three incoming water temperatures ( 11°C, 13°C, 19°C ). The maximum COP was calculated to be above 5.5. (Nadim, Chris, Sean)
Finished final design powerpoint presentation. (Everyone)
The simulation is done. (Xavier)
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finish Solidworks model and design section of report by tomorrow 3/1 (Cara, Sean)
Finish second draft of report by Friday. (Everyone)
Finish the second set of tests for the three incoming temperatures by Friday 3/2. (Everyone)
Finish the second set of tests for the two different flow rates Sat-Sun 3/3-4. (Everyone)
Calculate/plot the COP curves for new data obtained from second set of tests (Nadim, Chris, Sean)
Start and hopefully finished ASHRAE test procedure by end of next week. (Everyone)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments
Do another set of tests for flow rates and then start ASHRAE testing.
Figure out final cost of system if it is to be installed into homes (hopefully apartment buildings).
Possibly look into UCSD newsletter or any sort of publicity for our system
Figure out how to cool the motor on the heat pump without lowering the energy efficiency (i.e preferably any means other than a fan)
Maybe look for cheaper sensors/data loggers if we have time
Instructor Comments from Last Meeting and Actions Taken to Address these Comments
Do another set of tests for constant cold temperatures, especially for the 13°C and re-plot the COPs.
Risks and Areas of Concern
The temperature of the hot tank doesn't seem to go up much for the 3:1 flow pattern.
Being able to receive any useful results from ASHRAE testing (System cannot raise temperature to 57°C in 1 hour)
Resources or Information Required but not Available
Schedule
3/1 Finish Solidworks model for overall system with sensors
3/2 Finish second draft of report
3/2 Finish second test for 11°C, 13°C, 19°C incoming water temperatures
3/4 Finish second test for 3.5:1 and 4:1 flow rates. Will do 3:1 too if there is extra time.
3/9 Finish first test following ASHRAE standards
Budget (list amount spent and amount remaining)
Progress on Report and Webpage
Report has been edited with consideration to instructor and TA comments. (Cara)
Extra sections and pictures have been added to the report (Cara, Sean)
Updated website to reflect updates in report and data/results from testing (Sean)
