4 TECHNOLOGIES IN SYMBIOSIS FOR YOUR WELL-BEING The Bernoulli system is a symbiosis of highly innovative technologies designed to interact among one another in order to obtain the maximum performance with as much saving as possible. The man is infinitely small compared to the nature but infinitely big when he decides to become a part of it. The Bernoulli system consists of three main technological elements: Bernoulli TDS accumulation tank, i.e. hot water accumulation tank with stratification disks, Bernoulli heat pump and Bernoulli control units. All components of the Bernoulli system were deliberately studied and created to work together, each element was designed to operate exclusively with the Bernoulli technologies. The Bernoulli heat pump, because of its uniqueness, cannot be combined with existing technologies and systems, so apart from an innovative method of heat generation we had to create all the accessories that would allow a revolutionary technology like that of the Bernoulli heat pump to be integrated in any existing system without further adjustments. 4

5 SYSTEM AND FUNCTIONING The Bernoulli heat pump works in a closed circuit without wasting water, using it not only for cooling of the core but also other components such as bearings and electric motor that would otherwise disperse the heat in the atmosphere lowering the performance and wasting energy. All the thermal energy recovered by the Bernoulli heat pump is brought to the hot water accumulation tank with stratification disks, ready for single uses. Service water for all different uses and at all different temperatures can be drawn from the accumulation tank with stratification disks. There are various outlets in the TDS accumulation tank, in the upper part for service water for high temperature installations, in the middle part for service water for low temperature installations. In order to optimize the TDS accumulation tank use, the return water of different temperatures coming from various installations is managed by different inlets signed with approximate temperature. The Bernoulli accumulation technology then automatically places the water depending on its temperature. The inlets of this particular accumulation tank cannot be used at the same time as outlets and vice versa, every opening has its specific function. Once the service water draw-off has been differentiated between high temperatures and/or middle/low temperatures the delivery temperature can be set also by a remote control, which makes the Bernoulli system extremely versatile, it can actually adapt to every type of existing installation without any structural modification. The Bernoulli system can satisfy also the most difficult requirements adjusting the flow and the delta temperature to the wide range of settings. Once the service water at high and/or medium/low temperature has been drawn, it can be used in many different ways; thanks to the TDS accumulation tank the Bernoulli heat pump isn't subject to efficiency losses caused by erroneous temperatures of return water because the TDS accumulation tank works as a "filter" delivering water at constant temperature to the core and to the cooling circuits. Besides, accumulating a lot of calorific value in the upper stratification disk, the Bernoulli system can be used in installations with variable consumption and thermal requirements. For example: in a system with the thermal requirements from 216 kw, a 54-kW Bernoulli heat pump operated for four hours or a 27-kW Bernoulli heat pump operated for eight hours a day can be used (however, the thermal calculation has to be verified by an authorized technician). 5

7 BERNOULLI DESCRIPTION The factors that distinguish the Bernoulli product from the other heat pumps are: constant performance irrespective of the outside operating temperature; high temperature delivery; low cost; small dimensions (also thanks to the fact that no external units or geothermal wells are necessary). The performance of traditional heat pumps (COP) declared by the producers is on average very high. However, during the use it s extremely difficult to achieve the saving that would be made with the declared performance because the traditional heat pump technology is strongly conditioned by the outside temperature. The declared performances (COP) are calculated in very narrow environmental conditions that are actually created very rarely by the user. To put up with the variable atmospheric conditions, the heat pumps are equipped with electrical resistances that however reduce the performances significantly and the combined use of the two technologies makes the pay-back much longer. At present, the Bernoulli heat pump is the only heat pump with a sealed chamber patented technology that allows the performance (minimum COP 3.10) during the whole year irrespective of the ambient conditions and temperatures. Another patented element of the Bernoulli technology allows to reach a very high delivery temperature currently limited to 110 C. Apart from obtaining a high quality heat in the TDS accumulation tank upper stratification disk, this delivery temperature allows the immediate production of hot sanitary water by means of heat exchangers. So as the normal heat pumps with the delivery temperature of 50/60 C could produce sanitary hot water, they have to accumulate it with the risk of a pathogenic agent intrusion. Despite all the advantages the Bernoulli system cost is not high at all. The saving achieved thanks to the low purchase price can be multiplied by low hourly operation costs from the long-term perspective. Another advantage is the smaller size in terms of dimensions and weight: the weight of a 27-kW Bernoulli heat pump is about 80 kg, while the weight of a 26-kW traditional heat pump is about 300 kg. Except from its small size, the Bernoulli heat pump is advantageous also from the point of view of the transportation and installation costs. Thanks to our patents, the Bernoulli system needs no external unit and/or geothermal wells. Besides, the absence of the external unit reduces the aesthetic impact and the noisiness of the heat pump. 7

9 ACCUMULATION TANK DESCRIPTION To ensure an optimal operation, the Bernoulli heat pump based on its heat output must be combined with a correctly dimensioned hot water accumulation tank with stratification disks. The TDS accumulation tank is a service water accumulation tank specifically designed and constructed to be operated in together with the Bernoulli heat pump. Its characteristics make it the best solution for the valorisation of the whole Bernoulli system and the only solution able to handle the generated stress. The TDS accumulation tank was designed to stratify the service water in three disks of different temperatures. The upper disk is used for supplying in the optimal way the high temperature thermal installations such as traditional radiators or fan coil units. By means of exchangers, it is also used for the immediate production of sanitary hot water. The temperature of the upper stratification disk ranges from 85 C to 90 C; with the use of the accumulated energy, this allows the delivery to keep a constant temperature also during the periods in which the energetic requirements are higher than the machine capacity. The cooled return water is not mixed with the water contained in the upper stratification disk but, based on the temperature, it s placed in the lower disks. The temperature of the intermediate disk ranges from 45 C to 60 C, which are the optimal values for handling the requirements of the low temperature installations such as the underfloor heating; it can be used also for the core cooling. The lower disk is used to avoid mixing the cold water and for the motor cooling. The Bernoulli system designed in this way allows to optimize and reuse water of different temperatures increasing the efficiency of the whole system. The figure is only for explanatory purposes. The Bernoulli stratification system is protected by a patent. 9

10 CONTROL UNIT DESCRIPTION The range of Bernoulli control units includes the CBAS control unit with its extension CEXT suitable for handling small installations for single uses where the calculation of the consumed heat is not necessary or primarily important. In case of large size installations where it's necessary to calculate the heat and its amount drawn by single consumers, the CDEB control unit is provided. This control unit is also equipped with specific software that automatically completes the energy bills. Both control units have the internet connection and remote control and allow to achieve better results with respect to the system management based on the seasonal climatic conditions. The control unit, depending on requirements, can change the delta temperature in different ways: it can work with motor operated three-way valves combined with circulator pumps with constant flow rate commanding directly the three-way valve motor; or, alternatively, it can work with manual three-way valves which first have to be roughly ground in the phase of installation, then the delta temperature can be changed modifying the flow rate and reducing the circulator pump capacity. The control unit commands the start-up of both the heat pump and the circulator pumps as well as the operation of the three-way valves in the whole system. The control unit regulates the delta temperature adjusting the operation of the three-way valves or the flow rate in order to keep it constant in time without negative impact on the performance of the Bernoulli system. The control unit also handles automatically all the requirements using the heat output accumulated in the hot water accumulation tank with stratification disks in the best possible way. Depending on the conditions and based on the requirement type, it s able to calculate the hour, the season and the temperature of the three different stratification disks of the accumulation tank as well as the outside temperature. When it s necessary it starts the heat pump or if its possible it delays its start-up due to a more demanding request in order to reduce the numer of start-ups and consequently the consumption of the Bernoulli heat pump to the minimum. The control unit not only starts up the Bernoulli heat pump by means of a flowmeter but it s also able to evaluate when hot sanitary water is required and thanks to the temperature sensors placed on 2 inlets and 2 outlets of the heat exchanger, it adjusts the flow rate of the pump or the three-way valve in order to ensure a constant delta temperature or a constant outlet temperature on the side of the hot sanitary water. The CDEB control unit used in large and/or centralized systems ensures the heat pump start-ups and the system operation, and also handles the heat accounting for single users dividing them by means of a specific software which is able to create graphs and tables with consumptions and automatically generate bills. 10

11 BERNOULLI DASHBOARD Apart from the control units for the system regulation, the Bernoulli heat pump is controlled by an internal PLC which manages all the delicate operating parameters of the turbine so as the necessary heat could be produced in the shortest time possible and with the minimum possible number of start-ups. The Bernoulli heat pump is equipped with two temperature sensors and two pressure sensors, the pressure and temperature values are monitored in both the system and the core in order to reach the values set in the accumulation tank in the shortest possible time. Thanks to the internal software, the Bernoulli heat pump autonomously calculates the curve of optimal partition; on the basis of the difference between the required values and the current values, the turbine will actually receive a command from the PLC to operate on a certain number of revolutions per minute.

14 ADVANTAGES This new system which generates heat for household and industrial sectors, absolutely ecological and with zero environmental impact, offers a lot of advantages compared to conventional systems because: It doesn't use combustion and that's why a flue-gas ducting is not necessary. It's not subject to technical verifications to be carried out by the Fire Department. It s not supplied by a fuel so it doesn t need to be connected to conventional energy sources (LPG, gas, methane). It s not subject to performance limitations due to low or high temperatures because it ensures optimal operation with the outside atmospheric temperature from 30 C to +50 C. It's not subject to emission controls since it doesn't produce any emissions. There are no fire risks because it s filled with water. The heat efficiency (minimum COP 3,10) achieved by the Bernoulli System is absolutely more performing and consequently cheaper as far as the operating costs are concerned. Tax reliefs are applied within energetic efficiency increase programs in accordance with applicable laws.
