I was inspired by the new DarkStar controller's wind speed learning features, and incorporated the same functionality into the Tiny VCS Wind Trigger. The Wind Trigger version of the Tiny VCS features a lower maximum sensed voltage (15V) for greater sensitivity, faster sample and update frequency, and minimal hysteresis. These features help provide optimal functionality for wind trigger applications.
After creating a video for the anemometer interface, I realized we didn't have a basic video explaining the park function and what makes the Track'n Park different from the TinyTracker series.
So...here it is:
For our first new product of '15, we introduce this basic temperature controller. There are lots of solar heating/cooling situations where only a single temperature sensor is needed and an advanced temperature differential controller is inappropriate, and this is an ideal thermostat type control at a great price. A 3 digit LED display shows temperature and also displays program parameters for easy customization including hysteresis, delay time, temp correction, and more.
New products are in the pipeline for this new year. We've got a dual-axis external sensor that should be ready to make it's debut by the beginning of March. We've come up with a vacuum formed dome design to create an ideal enclosure. The attached pictures show a prototype unit. One of the nice features is the built in light vane which should make for accurate solar aiming. Also shown is one of the rough domes fresh from the vacuum former before it's been cut from the sheet of PET plastic.
I managed to inadvertently move the camera when I started recording, but still ended up with a useful video that shows how our new compound parabolic ribs and heat fins go together to create a solar trough system for heating water.
Home CSP Components used:
- 5 compound parabolic ribs
- 2 dual channel heat fins
One of the challenges I encountered while developing a parabolic trough design was finding a suitable heat fin for the focal plane. Existing ones on the market are all single channel designs. While these work fine for normal non-concentrating flat panel absorption designs, with the higher flux levels of a compound parabolic trough they leave something to be desired.
