The overall objective of this research is to design, construct, install, and troubleshoot a data acquisition system to monitor water addition effects on buried heat exchanger performance for a horizontal closed-loop ground-coupled heat pump system. Four specific sub-objectives have been identified as a logical sequence of steps toward the 3 achievement of the project objective. They are as follows: 1. Install measurement transducers to monitor temperature distribution around two horizontal heat exchangers, one with sand/water addition backfill and one with in site soil backfill and no water addition. 2. Design, construct and install data acquisition hardware to record data obtained with the temperature transducers at specified time intervals. 3. Write and implement control software to control the data acquisition hardware. 4. Obtain initial heat exchanger and soil temperature data to confirm that the data acquisition system is operating properly and to help identify potential changes to the data acquisition system that will provide higher quality data.
