Hello,
People like lower temperatures for some times, and higher temperatures for other times. It seems to need a lot of electricity energy..
Heat pumps, especially in the form of refrigerant based compressor systems, and also peltier based systems, are capable of controlling heat flow with electricity.
By considering and harmonizing all the heating and cooling needs of a local system with all the available heating and cooling sources, it should be possible to enjoy both more reliably with even less energy use than historically common methods.
Arduino helps many creative experimenters measure temperature and switch DC coolant pump every day why not measure temperature of multiple places on RV or home or other place, and then have a small computer automatically harvest heat from whichever sources are providing the most at that time and feed that to a heat pump?
Please help me fill in this graph..
One incarnation of the idea is that if the air is warm and it's sunny, the panels are probably quite warm too. Use a heat pump to move heat from backside of photovoltaic panels and from air, to serve water heater BTUs.
Or, if it's cold outside, supplement heat coming from the air with heat from the backside of the panels.
Of course it's a bad idea to pump endless amounts of heat into a photovoltaic panel, but it's safe to pump heat back into them if the temperature stays below whatever safe range that minimizes PV production loss. This would happen on a just slightly too warm evening. Pump a small amount of heat into the back of the panels at night to cool the inside air. The breeze would whisk that heat away easily from roof mounted solar panels.
Does anyone currently use their solar panels as water source heat pump? What is the performance like? How are cloudy days?
What sort of interesting circuits of heat can you imagine that haven't already been realized in practice?
