With the Enerfizentia thermodynamic solar panels, water can be heated or cooled through the principles of thermodynamics with energy savings well above average. Their installation for replacement of traditional fossil fuels (propane / natural gas / diesel) in applications such as hot sanitary water, pools and heating and /or air conditioning can achieve savings of over 70 %.
Enerfizentia thermodynamic solar technology achieves average annual COPs (Coefficient of Performance) above 4, energy savings over 70% and economic savings of some 50 % compared to other energy sources. These projects offer investment return periods of about 5 years.
This new technology does not destroy the existing installation, but prevents it from operating.
This system is particularly suited to address medium and large hot water demands. This is the case of hotels, hospitals, nursing homes, sports centers, swimming pools, spas, multifamily housing, and other facilities, making great use of hot water while using fossil fuels.
Enerfizentia facilities consist of high efficiency heat pumps due to increased evaporation zone comprised of a series of thermodynamic solar panels. These panels are exposed to direct sunlight, powering a cycle capable of cooling and heating water to 65 °C, in all weather conditions, all year round, day and night.
The thermodynamic solar panels use an environmentally friendly refrigerant fluid flowing at low temperature (-10 ° C). As the 134 A refrigerant moves through panels, it captures solar radiation incident on the panel and ambient energy. The temperature difference caused by external agents such as sun, rain or wind ensures that the fluid evaporates. The compressor vacuums this hot gas and compresses it, raising its temperature and pressure.
The fluid enters into the condenser formed by a coil surrounding the container (food safety), where the energy is transferred from the fluid to the water inside. At high pressure and after much of its heat has been yielded to the condenser, the refrigerant reaches the expansion valve in the liquid phase again. Here it is subjected to a reduction in pressure that causes fluid to be able to get back into the panels.
Advantages of thermodynamics
There are several advantages over other solar options. First, the flexibility of installation, in addition, although the direct sunlight is beneficial, is not necessary and they can be placed in vertical or horizontal position and in any area.
Furthermore, due to the low weight of the panels (ca. 8 kg), there is no need to reinforce the surface where they are placed and they also have reduced dimensions (each panel is 1.70 x 0.80 m x 2) .
The panels offer aesthetical versatility. In addition to their preferable black color, other colors are available according to requirement of the project. Another great advantage is their robustness, being made of 30 micron anodized aluminum sheet to offer a lifespan of over 25 years. A further advantage is that, being thermal makes it a very efficient system. It heats water up to 65 º day or night, on cloudy, rainy, windy or snowy days.
Finally, they feature low maintenance cost resulting from the closed loop that just makes it necessary to check for leaks in the circuit and to ensure that the gas charge is correct.
