Energy Saving & Recovery
Technology, systems, plant, structure, offer, possibilities
There are many different ways to save energy or recover a large part of it, such as dissipating heat, generating energy or, for example, detecting an unnecessary load and switching it off. Modern systems make it possible to permanently reduce energy consumption by up to 85%. Self-sufficient systems are also possible.
This is Energy Saving & Recovery
The energy transition is here! In times of rising costs for electricity, gas, water, wood pellets, etc., there is not only an opportunity to save money, but also to do something good for the environment. The potential to save energy in existing facilities such as saunas or general wellness facilities is gigantic! It works even better if the technical equipment and system are designed from the outset to save or even recover energy, and this is exactly where we come into play as a professional system constructor for energy saving and recovery. One of the most popular ways to save energy quickly and easily is not to use it in the first place. Where are your consumers located, is the heating level and the flow set correctly and necessary, does the ventilation have to run permanently and are there old devices that need to be replaced or are even unnecessary? We clarify these legitimate questions with you on site and measure the loads and identify consumers and configurations that can quickly save 10-15% across the board.
In addition to the general switching off or shutting down of unnecessary consumers, there is also the possibility of saving energy through in-house production. Modern solar systems from 10-20KW, the so-called small/system systems, with a corresponding 3-phase feed-in system and load distribution can temporarily reduce the purchased energy with corresponding active consumption, or even temporarily, on sunny days, completely cancel it out. Storing solar energy only makes sense if the solar system is overproportioned and storing the superfluous energy is possible at all. Here, the future owner should also take into account the wear and tear of the storage systems (battery) and high acquisition costs, which do not arise with direct feed-in taking into account the base load, since only the pure panels and controls and the current transformer
(inverter) is required and the current is consumed directly. For example, if you have a base load of approx. 10 KW/h from 8:00 a.m. to 8:00 p.m., a suitable solar system between 10 - 15 KW/h is just right for you. Without sun, however, no energy flows here either and the excess energy that may have been generated is then fed into the grid without storage and paid for accordingly or, depending on the contract, stored for you. As you can see, there are a wide variety of solutions and approaches. The recovery of energy is a bit more complex, but works day and night compared to solar energy. With a classic energy recovery, it is not the electricity that is recovered, but the converted form of the electricity. In the example of a sauna system with 10KW/h, a lot of electricity is converted into heat energy, which is slowly distributed in the sauna cabin.
With an increasing number of guests in the sauna, air circulation has to be ensured, so fresh cold air comes in that has to be reheated and the warm, used air goes out of the building, which was not the case before such a long time. With the rising energy costs and advancing technology and control options and sensor technology, things are different today. Modern systems use the sauna's waste heat, which would otherwise end up outside, to warm the fresh air just outside the sauna, minimizing the energy demand required by the sauna heater and bringing the room up to the desired temperature. For example, the flow temperature of the air can be 40-50° instead of 20° and the difference that the sauna heater has to overcome is only 30°-40° instead of 60° for an 80° setting temperature, which means that off the hourly consumption of 10KW/h means only 6-8KW/h potential energy requirement. In combination with a solar system, it can happen that you do not need any additional energy from energy suppliers, even if the sun is not full.
A simple calculation makes it clear how this affects finances and costs. 10KW/h, 8h daily on approx. 350 days per year at 40ct/KW result in about 11,200€ for the operation of the sauna. If we now only recover 25% with energy recovery and heat, the cost factor is reduced to around €8,400 per year. With an additional system and taking into account that the solar radiation is not 100% all year round, there is another 35 - 50% savings potential. The end result would then be, instead of €11,200, only around €4,000 for regular operation of the sample sauna facility. The savings potential is thus already less than half and that every year. In larger systems, the savings potential is many times higher.
The combination of unnecessary consumers, correct settings in the control electronics, energy recovery & the combination of renewable energies is an unbeatable combination and saves money over many years.
