Follow on Google News | Performance Verification System Saves Nursing Home Considerable Energy CostsBy: CAS DataLoggers CAS DataLoggers provided a performance verification system for a solar water heating system installed in a nursing home. The solar collectors, installed by a local HVAC (https://en.wikipedia.org/ Installation After the caller described this application, a CAS DataLoggers Applications Specialist provided the company with a dataTaker DT80 Universal Input Data Logger (https://www.dataloggerinc.com/ Usage The DT80 is programmed to sample the water temperatures from the thermistors and the pulse signals from the flow sensors once a minute. Using the calculations capability of the logger, it was possible to calculate the amount of energy captured by the solar collectors using the temperature difference between the incoming and outgoing water and the flow rate. Also, alarms were set-up to activate pumps if the temperature in the system got to high on a warm, sunny day. All of the measured data was stored in the loggers 128MB of on-board flash memory allowing months' worth of local storage. Using the dataTaker's built-in FTP client, data it automatically uploaded to a server in the HVAC contractor's office for analysis and long term archiving. This data enables the HVAC company to remotely monitor the system's water flow rate and the inlet/outlet water temperature. They can calculate how much energy the system is capturing and how much money it is saving the facility every week, month or year. Benefits The HVAC provider found that the dataTaker DT80 easily handled all of their monitoring and control requirements. Temperatures were accurately captured from the thermistors, flow rates from flow sensor with 4-20 mA outputs and run times for the different pumps. The DT80 is able to not only record but also calculate the heat gain and the solar collector's BTUs which the customer can use as a demonstration of cost savings. The HVAC provider is confident that their solar heating system will pay for itself in a few years, and the dataTaker is their way to provide performance verification for the project.
