Description

Predmet izuma je solarni sistem, oziroma natančneje solarna naprava, prednostno z energetskimi strešniki, z vgrajeno toplotno črpalko.The subject of the invention is a solar system, or more specifically a solar device, preferably with energy roofs, with an integrated heat pump.

Izum je po mednarodni patentni klasifikaciji predvidoma uvrščen v F 24J 2/00 in dodatno v F 24J 2/42.According to the international patent classification, the invention is envisaged to be classified in F 24J 2/00 and additionally in F 24J 2/42.

Tehnični problem, ki ga rešuje izum, je takšna konstrukcija solarnega sistema, s katero bo mogoče sanitarno vodo in vodo za sisteme ogrevanja, razen z energetskimi strešniki, dodatno ogrevati še s toplotno črpalko.A technical problem solved by the invention is the construction of a solar system that will allow the sanitary water and water for heating systems to be additionally heated by a heat pump, except for energy roofing.

Znani so standardni solarni sistemi za ogrevanje vode za ogrevanje in sanitarne vode s pomočjo toplovodnih kotlov in dodatno še s solarnimi kolektorji. Rešitev je zapletena, zahtevna in zato nepraktična.Standard solar systems for heating water and domestic hot water using hot water boilers and additionally with solar collectors are known. The solution is complex, challenging and therefore impractical.

Druga znana rešitev je po patentu SI 9800147, ki omogoča pretvarjanje sončne energije v toplotno ali električno s pomočjo energetskih, oziroma solarnih strešnikov z vgrajenimi kolektorji. Rešitev ima to pomanjkljivost, da ne omogoča dovolj akumulacijske toplote in s tem dovolj velikega temperaturnega nivoja za ogrevanje vode.Another known solution is the patent SI 9800147, which enables the conversion of solar energy into thermal or electrical by means of energy or solar roof tiles with built-in collectors. The solution has the disadvantage that it does not allow sufficient heat accumulation and therefore a sufficiently high temperature level to heat the water.

Skupna značilnost navedenih znanih rešitev je ogrevanje sanitarne vode in vode za ogrevanje s koriščenjem sončne energije. Variante so v uporabi dodatne opreme za doseganje temperaturnega nivoja segrete vode. Problem, ki je ostal nerešen, je predvsem v nezadovoljivi, zahtevni in nepraktični dodatni opremi, ki bi potreben temperaturni nivo vode zagotavljala v vseh letnih časih in ob različnih pogojih.A common feature of these known solutions is the heating of domestic hot water and solar water. The variants are used accessories to reach the temperature level of the heated water. The problem that remains unsolved is, in particular, unsatisfactory, demanding and impractical accessories that would provide the required water temperature in all seasons and under different conditions.

Po izumu je problem rešen s solarnim sistemom, ki ima med energetske strešnike in bojler dodatno vgrajeno še toplotno črpalko. Izum bo opisan na prednostnem izvedbenem primeru in sliki, ki prikazuje shematski prikaz solarnega sistema po izumu.According to the invention, the problem is solved with a solar system, which has an additional heat pump between the energy tiles and the boiler. The invention will be described in the preferred embodiment and in the figure showing a schematic representation of the solar system according to the invention.

Solarni sistem prednostno tvorijo solarni strešniki 1, bojler 2 in toplotna črpalka 3.The solar system is preferably formed by solar roof tiles 1, water heater 2 and heat pump 3.

V bojler 2 vodi cev 4 za dovod sanitarne vode iz vodovodnega omrežja stanovanjskega ali drugega poljubnega objekta. Bojler 2 je s toplotno črpalko 3 pretočno povezan s cevjo 5 in v bistvu predstavlja sekundami krog sistema.In the water heater 2 there is a pipe 4 for the supply of sanitary water from the water supply network of a residential or any other facility. Water heater 2 is connected to the pipe 5 via a heat pump 3 and essentially represents the circuit of the system for seconds.

Toplotna črpalka 3 je z cevjo 6 pretočno povezana z cevnim registrom 7 in ta dalje s pripadajočimi solarnimi strešniki 1, kar predstavlja primarni krog sistema.The heat pump 3 is connected to the pipe register 7 through the pipe 6 and then to the associated solar roof tiles 1, which represents the primary circuit of the system.

V tako imenovanem povratnem vodu je od, oziroma iz solarnih strešnikov 1 speljana cev 8 in jih prav tako pretočno povezuje s toplotno črpalko 3.In the so-called return line, a tube 8 runs from or from the solar roof tiles 1 and also connects them to the heat pump 3.

Dalje je toplotna črpalka 3 pretočno spojena z bojlerjem 2, iz katerega vodi cev 10 nazaj v omrežje sanitarne vode ali/in v naprave za talno ali radiatorsko ogrevanje.Further, the heat pump 3 is flow-connected to the boiler 2, from which the pipe 10 goes back to the DHW network and / and to the underfloor or radiator heating devices.

Kot temeljni vir toplotne energije služi temperatura okolice, torej sončna toplota oziroma temperatura zraka, ki jo dobivamo preko solarnih strešnikov 1, ki so običajno napolnjeni z črno obarvano vodo ali drugim ustreznim črno obarvanim tekočim medijem za prenos toplote, kar omogoča doseganje večjega absorpcijskega koeficienta sončne svetlobe. Dodatni vir toplotne energije predstavlja toplotna črpalka 3. Iz solarnih strešnikov 1 vstopa segreta oziroma topla voda v uparjalnik toplotne črpalke 3 skozi cev 8, kjer hladilnemu sredstvu odda svojo toploto. Pri tem velja, daje izkoristek toplotne črpalke 3 tem večji, čim višja je temperatura energije, ki jo toplotna črpalka 3 porablja. Iz toplotne črpalke 3 se dodatno segreta, torej še bolj topla voda, izteka v bojler 2 in nato po cevi 10 dalje do končnega porabnika, kot topla sanitarna voda ali topla voda za ogrevanje prostorov ali podobno.The ambient temperature is the primary source of thermal energy, that is, solar heat or air temperature obtained through solar roof tiles 1, which are typically filled with black-colored water or other suitable black-colored liquid medium for heat transfer, which enables a higher solar absorption coefficient to be achieved. of light. An additional source of heat energy is heat pump 3. From the solar tiles 1, heated or warm water enters the evaporator of the heat pump 3 through a tube 8 where it radiates its heat to the coolant. The higher the efficiency of the heat pump 3, the higher the temperature of the energy consumed by the heat pump 3. The heat pump 3 is additionally heated, ie even hotter water, flows into the water heater 2 and then flows through the pipe 10 to the final consumer as hot water or hot water for space heating or the like.

Toplotna črpalka 3, vgrajena v sistem po izumu, je lahko izvedbe zrak-voda ali vodavoda. Za toplotne črpalke 3 zrak-voda velja, daje temperatura energije enaka temperaturi okolice, pri izvedbi voda-voda pa enaka temperaturi podtalnice. Prednost toplotnih črpalk 3 izvedbe voda-voda je predvsem v tem, da lahko nemoteno obratujejo skozi vso kurilno sezono, oziroma skozi vse leto. Uporaba toplotnih črpalk 3 izvedbe zrak-voda je smiselna samo do zunanje temperature zraka - 1°C, pri nižjih manj. Iz tega sledi, daje smiselno, da toplotna črpalka 3 zrak-voda obratuje bivalentno, torej z uporabo dodatnega vira ogrevanja vode, kot so plin, elektrika ali kurilno olje.The heat pump 3 installed in the system according to the invention may be air-to-water or water-pipe versions. For air-to-water heat pumps 3, the energy temperature is considered to be equal to the ambient temperature and, in the case of water-to-water, the groundwater temperature. The advantage of water-to-water heat pumps 3 is that they can run smoothly throughout the heating season or throughout the year. The use of air-to-water heat pumps 3 makes sense only to the outside air temperature - 1 ° C, at lower temperatures. It follows that it makes sense that the air-to-water heat pump 3 operates in a bivalent manner, ie by using an additional source of water heating such as gas, electricity or heating oil.

Meritve so pokazale, daje ob jasnem vremenu solarni sistem po izumu, ki obsega solarne strešnike 1 in toplotno črpalko 3, z energetskega vidika optimalno ustrezna rešitev za ogrevanje stanovanjskih hiš, tako prostorov, kot sanitarne vode. Rezultat meritev je pokazal tudi, da je potrebno pri načrtovanju izgradnje tovrstnega sistema za ogrevanje vode v stanovanjskih ali drugih objektih upoštevati, daje potrebno za 1 kW toplotne moči toplotne črpalke 3, brez izolacije na spodnji strani, vgraditi v streho objekta minimalno 4 m² solarnih strešnikov 1.Measurements have shown that, in clear weather, the solar system according to the invention, comprising solar roof tiles 1 and a heat pump 3, is, from an energy point of view, the optimum solution for heating residential buildings, both rooms and sanitary water. The results of the measurements also showed that when planning the construction of such a system for heating water in residential or other buildings, it is necessary to consider that for a 1 kW heat output of the heat pump 3, without insulation on the underside, a minimum of 4 m ² solar panels should be installed in the roof of the building. roof tiles 1.

Dalje velja, da je v območjih z večjim številom jasnih in/ali delno jasnih dni v letu, smotrna uporaba toplotne črpalke 3 izvedbe zrak-voda in obratno.Furthermore, in areas with a greater number of clear and / or partially clear days of the year, it is advisable to use an air-to-water heat pump 3 and vice versa.

Toplotne potrebe zgradb so, kot je predhodno že povedano, odvisne predvsem od zunanje temperature, ki običajno dosegajo najnižje vrednosti le kratko obdobje znotraj kurilne sezone. Zato je ogrevna moč toplotne črpalke 3 odvisna tako od toplotnega izvora okolice, v našem primeru ogrevanja vode s solarnimi strešniki 1 in od toplotnega ponora, torej od obstoječega sistema ogrevanja v prostoru.The thermal needs of buildings, as previously stated, depend mainly on the outside temperature, which usually reaches the lowest values for only a short period during the heating season. Therefore, the heat output of heat pump 3 depends on both the thermal source of the surroundings, in our case the heating of the water by solar roof tiles 1 and the heat sink, that is, on the existing space heating system.

Uporaba toplotne črpalke 3 v solarnem sistemu po izumu je za objekte, predvsem stanovanjske objekte smiselna in racionalna predvsem v kombinaciji s talnim gretjem, ki zahteva najnižjo temperaturo grelne vode.The use of the heat pump 3 in the solar system according to the invention is reasonable and rational for buildings, especially residential buildings, especially in combination with underfloor heating, which requires the lowest heating water temperature.
