Temperature Management through Phase Change Materials

Installation of PCM22P (72 Fahrenheit) at AB-Tech Sycamore Greenhouse

These are the most recent temperature recordings we've received from our PCM fittings at the greenhouse.  The PCM pipes were originally installed earlier this year.  On the left side, it is clear that the inside temperatures (green) far exceeded the outside temperatures (red) during the day.  Starting in April, after the phase change materials were added to the North wall, the indoor climate stabilizes and remains consistently cooler during the day and warmer at night than the outdoor thermal readings.  We'll continue to monitor the temperatures over the winter and will share the results as we collect them.
