Stav technikyState of the art
Teplo v pare použité na prípravu teplej úžitkovej vody (TÚV) je potrebné merať kvôli vyúčtovaniu. Toto sa doteraz robí viacerými druhmi meračov, tieto sa delia na priame a nepriame.The steam heat used to produce domestic hot water (DHW) must be measured for billing. This has been done so far by several types of meters, these are divided into direct and indirect.
Priame merače sú umiestnené na vstupe pary do príslušných zariadení (najčastejšie bojlerov TÚV), sú nepresné a nespoľahlivé. Dôvodom je skutočnosť, že v procese ohrevu TÚV často značne fluktuje množstvo pary a jej kvalita, najmä jej vlhkosť sa mení. Zvýšenie vlhkosti spôsobené ochladzovaním pary prostredím prakticky sa nedá nijakým spôsobom odmerať. Táto okolnosť môže podstatným spôsobom znehodnotiť meranie.Direct meters are located at the steam inlet to the relevant equipment (most often DHW boilers), they are inaccurate and unreliable. This is due to the fact that the amount of steam often fluctuates considerably in the process of DHW heating and its quality, especially its humidity, changes. The increase in humidity caused by the cooling of the vapor by the environment is virtually impossible to measure. This circumstance may significantly impair measurement.
Nepriame merače sú založené na stotožnení množstva pary s jej kondenzátom. Kondenzát pary je v kvapalnej forme a teda ľahšie merateľný. Týmto je odstránená neschopnosť priamych meračov vyhovojúco zaznamenávať fluktujúce množstvo pary. Druhá vada priamych meračov - neschopnosť vyhodnotiť zhoršenie úrovne kvality pary aj u nepriamych meračov zostáva.Indirect meters are based on identifying the amount of steam with its condensate. The steam condensate is in liquid form and thus easier to measure. This eliminates the inability of direct meters to satisfactorily record fluctuating amounts of steam. The second defect of direct meters - the inability to evaluate the deterioration of the steam quality level even in indirect meters remains.
Podstata vynálezuSUMMARY OF THE INVENTION
Neschopnosť doterajších meračov tepla v pare použitých na meranie spotreby tepla použitej na prípravu teplej úžitkovej vody určiť vlhkosť pary odstraňuje patentové zariadenie, tu sa meranie spotreby tepla prenáša na stranu vody, voda v procese ohrevu spotrebúva teplo z pary na krytie troch položiek:The inability of the existing steam heat meters used to measure the heat used to prepare hot water to determine the steam moisture is removed by the patent device, where the heat consumption measurement is transferred to the water side, the water in the heating process consumes heat from the steam to cover three items:
(1) Bezprostredne na vlastný ohrev, (2) na krytie tepelných strát vzniknutých cirkuláciou vody a (3) na krytie strát sálaním zariadenia (4), všetky tri položky sú (1), (2), (3) spojito vyhodnocované v integrátore.(1) Immediately for self-heating, (2) to cover thermal losses caused by water circulation, and (3) to cover losses of radiation from the appliance (4), all three items being (1), (2), (3) continuously evaluated in the integrator .
Podstata vynálezu spočíva v tom, že integrátor vypočítava teplo z pary použité (1) bezprostredne na ohrev studenej vody pomocou impulzov od čidiel prietoku a teploty studenej vody a teploty ohriatej vody, (2) Teplo spotrebované na krytie strát cirkuláciou ohriatej vody pomocou prietokomera a teplomera cirkulujúcej vody a teplomera ohriatej a konečne, (3) pripočítaním tepelných strát vzniknutých sálaním do okolia - stanovených externým výpočtom a vložených do integrátora. Týmto spôsobom sa v integrátore zaznamenajú všetky 3 položky spotreby tepla využité na prípravu teplej úžitkovej vody, toto u doterajších meračov nie je možné. Podľa vzájomného pomeru veľkosti položiek (1), (2), (3) sa stanoví miera hospodárnosti prípravy teplej úžitkovej vody.SUMMARY OF THE INVENTION is that the integrator calculates the heat from the steam used (1) immediately for heating the cold water by means of pulses from the flow and temperature sensors of the cold water and the hot water temperature. circulating water and thermometer heated and finally, (3) adding the heat losses generated by radiation into the environment - determined by external calculation and inserted into the integrator. In this way, all 3 heat consumption items used for domestic hot water production are recorded in the integrator, this is not possible with previous meters. Depending on the size ratio of items (1), (2), (3), the economic efficiency of hot water production is determined.

Príklad uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Je uvedený na obrázku č. 1. Para prúdi potrubím I do zariadenia 4 a odteká vo forme kondenzátu potrubím 2. Studená voda prúdi potrubím 5 do zariadenia 4 a je v ňom ohrievaná na žiadanú teplotu parou prúdiacou do zariadenia 4 potrubím 1. Voda ohriata parou v zariadení 4 (t.j. teplá úžitková voda, TÚV)je účinkom tlaku studenej vody z potrubia 5 tlačená potrubím 8 do spotreby TÚV.It is shown in figure no. 1. The steam flows through line I to the device 4 and flows in the form of condensate through line 2. The cold water flows through line 5 to the device 4 and is heated to the desired temperature by steam flowing into the device 4 through line 1. Water heated by steam in the device 4 (ie domestic hot water (DHW) is pushed by pipe 8 into the DHW consumption by means of cold water pressure from line 5.
Integrátor 13 stanovuje spotrebu tepla v pare na prípravu teplej úžitkovej vody na základe súčtu troch sčítaných taktov:The integrator 13 determines the heat consumption in the steam for the production of hot service water on the basis of the sum of the three counted measures:
Prvý sčítanec je určený údajom prietokomera ]_ a rozdielu teplôt teplomerov 12 a 6.The first addition is determined by the flowmeter 11 and the temperature difference of the thermometers 12 and 6.
Druhý sčítanec je určený údajom prietokomera 10 a rozdielu teplôt teplomerov 12 a H·The second addition is determined by the flowmeter 10 and the temperature difference between thermometers 12 and H ·
Tretí sčítanec je vkladaný do intergrátora 13 ako počiatočná diskrétna hodnota tepelných strát vzniknutých sálaním zariadenia do okolitého prostredia (napr. do kotolne). Tretí sčítanec sa určuje externým výpočtom individuálne pre každý prípad a mieru jeho aplikácie posudzuje integrátor 13 pomocou teplomerov 3.12. Integrátor podľa hodnoty teploty vody danej teplomerom 12 môže určovať tú časť strát, ktorá prísluší zariadeniu 4.The third addition is inserted into the integrator 13 as the initial discrete value of the heat losses generated by the radiation of the device to the surrounding environment (e.g., the boiler room). The third addition is determined by an external calculation individually for each case and the degree of application is assessed by the integrator 13 using thermometers 3.12. The integrator according to the value of the water temperature given by the thermometer 12 can determine the part of the losses that belongs to the device 4.
Dostatočnosť tepelného využitia pary a jej kondenzátu v zariadení 4 je posudzovaná podľa teploty kondenzátu určenej teplomerom 3.The sufficiency of the thermal utilization of steam and its condensate in the apparatus 4 is judged by the temperature of the condensate determined by the thermometer 3.
