IN THE HOME OF THE FUTURE, appliances will be linked like hardware on a computer. Just like a new wireless keyboard, printer or touch screen monitor, you need only place the new appliance into service and it will communicate on a machine to machine basis (M2M), providing useful data for energy and performance optimization. But electronic communication is one part of the equation. There is also the concept of “Thermal Communication”.
The household appliances in our “Celestia Home of the Future” will prompt, “Do you really want to start the washing machine now, while the shower is on and the dishwasher is running? Please allow me [the smart M2M system] to start this for you later, when energy and water consumption can be optimized, saving 1.3 kWh of peak load energy consumption.” This simple logic and communication between machines, homes and communities will defer infrastructure costs for building of power plants that could be averted.
Let’s focus in on this thought process just a little further. In our home of the future we have M2M cooperative communication for the purpose of optimizing energy consumption and reducing peak loads. We can do better.
Consider for a moment the cooking appliances, lights, computers, refrigerator and even your blow dryers and curling irons that add to the cooling load in your home. These are all sources of energy; energy that actually adds to your summer cooling loads, and costs you money in the way of energy consumption twice. The reason it cost you twice is that the heat produced goes up through your return air ductwork and ultimately is exhausted through outside air exchange, taking increased energy for your air-conditioner to move that heat outside. Summertime is normally the biggest peak in electrical energy consumption, and you can see why. Between internal heat gains and air-conditioning needs of the home, were moving an awful lot of heat. But there are places that heat could be used if only we could get it there…
We need hot water for our dishwashers and washing machines, not to mention showers and baths. If you have a pool or spa, you can bet they could use some heat much of the time. Are you getting the concept? There is a way to move the extra heat in our home (or business) somewhere that it could be used.
Consider the heat going down the drain, literally. The drainage from your dishwasher, shower, and washing machine will pass through an Energy Recovery Exchanger (ERE), wringing every usable BTU out of the wastewater, and providing an impressive boost of energy input to your geothermal heat pump for your wintertime home heating needs.
The PV array integrated into the Celestia Home’s roof provides a solar thermal boost as well as precious electricity. Remember that much of the energy needed for the home need not be in the form of electricity (hot water for dishes, showers, laundry, and even a boost to the geothermal heat pump).
Because geothermal heating and cooling is a water sourced technology (unlike the old typical “air source” heat pump equipment), all of the heat removed from your home is entrained in a one inch pipeline that can be diverted to any place it’s needed. In the “Celestia Home of the Future”, the waste heat is diverted to usable heat for your dishwasher, washing machine, showers and baths, spa heating and pool heating. And because sometimes you don’t need that shower, bath, or load of dishes done exactly the time the waste heat is been pumped out, your Celestia Smart Home will use its M2M logic to operate the appliances at the perfect time in synch with your family’s needs.The Celestia Kitchen will truly maximize resources.
The Celestia Home of the Future is a truly smart home, built on a geothermal foundation, allowing Machine to Machine (M2M) communication, enhancing the thermal communication between all of your heat producing and consuming appliances and processes. With the significantly reduced electrical loads, the Celestia Home needs a smaller Solar PV array, making Solar and Geothermal a perfect match, saving energy, space, and precious resources.
