ZARIADENIE NA VÝROBU STUDENEJ VODY NA CHLADENIE PRIESTOROVDEVICE COOLING WATER PRODUCTION EQUIPMENT
Oblasť technikyTechnical field
Vynález sa týka zariadenia na výrobu studenej vody na chladenie priestorov, najmä pre chladiace plochy a chladiče v príslušenstve budov, najmä pre chladiace plochy s chladiacim zariadením a s pred ním zapojeným odparovacím chladičom, cez ktorý prúdi chladiaca kvapalina a vzduch.The invention relates to a device for producing cold water for space cooling, in particular for cooling surfaces and coolers in building accessories, in particular for cooling surfaces with a cooling device and an evaporator cooler connected thereto, through which coolant and air flow.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Výroba studenej vody pre chladiace plochy pomocou chladiaceho zariadenia je známa.The production of cold water for cooling surfaces using a cooling device is known.
>>
Taktiež je pritom známe, ako ochladiť kondenzátor, resp. skvapalňovač s výmenníkom tepla, cez ktorý prúdi vzduch. Tiež je známe, že vstrekovaním vody do výmenníka tepla, sa môže zlepšiť odvod tepla (mokrá chladiaca veža).It is also known how to cool the capacitor or the condenser. a liquefier with a heat exchanger through which air flows. It is also known that by injecting water into the heat exchanger, heat dissipation (wet cooling tower) can be improved.
Úlohou vynálezu je zlepšenie výkonu zariadenia spôsobom spomenutým v úvode, pri nízkych zriaďovacích nákladoch.SUMMARY OF THE INVENTION The object of the invention is to improve the performance of the apparatus in the manner mentioned in the introduction, at low installation costs.
Podstata vynálezuSUMMARY OF THE INVENTION
Odstránenie nedostatkov a zlepšenie existujúceho stavu zabezpečuje riešenie podľa vynálezu, ktorého podstata spočíva v tom, že zariadenie na výrobu studenej vody na chladenie priestorov chladiacimi plochami a chladičmi vo vybaveniach budov, najmä pre chladiace plochy s chladiacim zariadením a s pred ním umiestneným odparovacím chladičom, cez ktorý preteká chladiaca kvapalina a vzduch je riešené tak, že do chladiaceho prúdu vzduchu odpaľovacieho chladiča je vstrekovaná voda a chladiaca kvapalina je vedená cez tepelný výmenník a kondenzátor alebo priamo do medzizásobníka alebo priamo k spotrebiču, pričom pred kondenzátor je zapojený vzduchový kondenzátor, ktorý je umiestnený v kanále na odvod vzduchu odpaľovacieho chladiča. Odparovací chladič je platňový tepelný výmenník z polypropylénu.The solution according to the invention is to eliminate the deficiencies and to improve the existing state of the art, in which the device for producing cold water for space cooling by means of cooling surfaces and coolers in building equipment, especially for cooling surfaces with cooling equipment and with a vaporizer cooler the coolant flows and the air is solved by injecting water into the coolant airflow of the blast cooler and the coolant is led through the heat exchanger and condenser or directly to the intermediate storage tank or directly to the appliance, with an air condenser located in front of the condenser. air outlet ducts of the blast cooler. The evaporator cooler is a polypropylene plate heat exchanger.
Podstata riešenia ďalej spočíva v tom, že v chladiacom okruhu chladiaceho zariadeniaThe essence of the solution further lies in the fact that in the cooling circuit of the cooling device
-2je pred expanzný ventil zaradený tepelný výmenník, cez ktorý prúdi voda, skôr ako sa voda privedie cez rozdeľovači systém odparovacieho chladiča do vonkajšieho prúdu vzduchu.-2, a heat exchanger is provided upstream of the expansion valve through which the water flows before the water is fed through the evaporative cooler distribution system to the external air flow.
Ďalej podstata riešenia spočíva v tom, že všetky časti chladiaceho zariadenia, odparovacieho chladiča, ako aj riadenia/ regulácie sú umiestnené v jednej skrini, pričom skriňa pozostáva z viacerých prenosných jednotiek.Further, the principle of the solution is that all parts of the cooling device, the evaporative cooler and the control / regulation are located in one housing, the housing consisting of several portable units.
Podstata riešenia spočíva tiež v tom, že ku kondenzátoru chladiaceho zariadenia je pripojený preklenovací obtok, spúšťaný ventilom.The essence of the solution is also that a bridging bypass, triggered by a valve, is connected to the condenser of the cooling device.
Úloha je prostredníctvom vynálezu riešená tak, že sa do chladiaceho vzduchu výmenníka tepla vstrekne voda a že chladiaca kvapalina alternatívne prúdi cez kondenzátor chladiaceho zariadenia, alebo priamo k spotrebiču, alebo do obidvoch súčasne. Vstrekovaním vody do výmenníka tepla na vzduchovej strane sa jednoduchým a úsporným spôsobom efektívnejšie aktivuje požadovaný chladiaci výkon. Toto je výhodné obzvlášť vtedy, keď sú požadované väčšie výkony - napríklad v lete. Vstrekovaním vody do výmenníka tepla, a tým podmieneným ochladzovaním vzduchu sa dosiahne odvod nahromadeného tepla pri nižšej úrovni teploty. Pri nižšej kondenzačnej teplote dosahuje chladiace zariadenie priaznivý výkon.The object of the invention is solved by injecting water into the cooling air of the heat exchanger and alternatively flowing the cooling liquid through the condenser of the cooling device, or directly to the appliance, or both. By injecting water into the heat exchanger on the air side, the required cooling capacity is activated more simply and economically. This is especially useful when higher power is required - for example in summer. By injecting water into the heat exchanger and thereby condensing the air, condensation of heat accumulated at a lower temperature level is achieved. At a lower condensing temperature, the cooling device achieves favorable performance.
Ako výhodné riešenie sa navrhuje, aby odparovací chladič bol platňový tepelný výmenník z polypropylénu. Nakoľko sa vo výmenníku tepla odparovacieho chladiča pracuje s vodou, hrá veľkú úlohu materiál, z ktorého je platňový tepelný výmenník vyrobený. Polypropylén je materiál, na ktorom - z dôvodu použitia vody - nedochádza k usadzovaniu pevných častíc.As a preferred solution, it is proposed that the evaporator cooler is a polypropylene plate heat exchanger. Since water is used in the evaporator cooler heat exchanger, the material from which the plate heat exchanger is made plays a large role. Polypropylene is a material on which - due to the use of water - no solid particles are deposited.
Je obzvlášť výhodné, keď je do chladiaceho okruhu chladiaceho zariadenia pred expanzný ventil zaradený výmenník tepla, cez ktorý prúdi voda, skôr ako sa voda privedie do prúdu vzduchu odparovacieho chladiča. Pomocou takéhoto ochladenia chladiaceho média pred jeho vstrekom do odparovača sa jednoduchým a ekologickým spôsobom dosiahne ďalšie zlepšenie výkonu.It is particularly preferred that a heat exchanger is provided upstream of the expansion valve into the cooling circuit of the cooling device before the water is introduced into the airflow of the evaporator cooler. By such cooling of the cooling medium before it is injected into the evaporator, further performance improvements are achieved in a simple and environmentally friendly manner.
-3Ďalšie zvýšenie chladiaceho výkonu sa dosiahne tým, že sa pred vodný kondenzátor zaradí vzduchový kondenzátor, ktorý je umiestnený v kanále na odvádzanie vzduchu, resp. v otvore na odvádzanie vzduchu.-3A further increase in cooling capacity is achieved by placing an air condenser in front of the water condenser, which is located in the air outlet duct, respectively. in the air outlet.
Ďalšia výhoda spočíva vo zvýšení teploty odvádzaného vzduchu a z toho vyplývajúceho zníženia relatívnej vlhkosti vzduchu. Tým sa zníži riziko vytvorenia kondenzátu v kanále na odvádzanie vzduchu. Vyparovaním aerosolov, existujúcich v odvádzanom vzduchu za odparovacím chladičom sa zlikvidujú životné podmienky baktérií, ktoré sa vo vnútri môžu nachádzať - najmä Legionella pneumophilla. Pritom je zvlášť výhodné, keď je vzduchový kondenzátor umiestnený v kanále na odvádzanie vzduchu v odpaľovacom chladiči.A further advantage lies in the increase in the temperature of the exhaust air and the resulting reduction in the relative humidity of the air. This reduces the risk of condensation forming in the air outlet duct. The evaporation of aerosols existing in the exhaust air downstream of the evaporator cooler destroys the living conditions of the bacteria that may be present - especially Legionella pneumophilla. In this case, it is particularly advantageous if the air condenser is located in the air outlet duct in the firing cooler.
Ďalšou výhodou je kompaktnosť zariadenia. Tým sa dá vyhnúť energetickým stratám, vznikajúcim zohrievaním potrubia chladiacej vody medzi jednotlivými časťami zariadenia, ako aj inak obvyklej spotrebe energie pre čerpadlá.Another advantage is the compactness of the device. This avoids the energy losses resulting from the heating of the cooling water pipe between the individual parts of the plant, as well as the otherwise usual energy consumption for the pumps.
Prehľad obrázkov na výkresochBRIEF DESCRIPTION OF THE DRAWINGS
Na pripojených výkresoch sú na obrázkoch schematicky znázornené a v ďalšom opísané dva rôzne príklady vyhotovenia zariadenia podľa vynálezu, pričom na obr. 1 je schematicky znázornený prvý príklad uskutočnenia vynálezu a na obr. 2 je schematicky znázornený druhý príklad uskutočnenia vynálezu.In the accompanying drawings, two different exemplary embodiments of the device according to the invention are schematically illustrated and described in the following. 1 schematically illustrates a first embodiment of the invention and FIG. 2 schematically shows a second embodiment of the invention.
Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Príklad 1Example 1
Prístroj, resp. zariadenie má chladiace zariadenie s chladiacim okruhom 1_, v ktorom je umiestnený kompresor (stláčacie zariadenie) 2. V smere prúdenia je za kompresorom 2 umiestnený kondenzátor (skvapalňovač) 3, ktorý je chladený druhým kvapalinovým okruhom 4, ktorý je detailnejšie opísaný nižšie. Z kondenzátora 3 sa dostáva chladiaca kvapalina cez expanzný ventil 5 k odparovaču 6, na ktorom je pripojený tretí okruh 7.The device, respectively. The apparatus has a cooling device with a cooling circuit 7 in which a compressor 2 is located. Downstream of the compressor 2, a condenser 3 is placed which is cooled by a second liquid circuit 4, which is described in more detail below. From the condenser 3, the coolant flows through the expansion valve 5 to the evaporator 6, to which the third circuit 7 is connected.
-4Chladiaci výkon, ktorý odovzdáva odparovač 6 do tretieho okruhu 7, sa privádza čerpadlom 8 do medzizásobníka 9. Z medzizásobníka 9 sa štvrtým okruhom 10 chladiaci výkon odovzdáva cez rozdeľovači systém 12 chladiacej ploche 11. Na kondenzátor 3 pripojený druhý kvapalinový okruh 4 je od čerpadla 13 vedený cez odparovací chladič 14, ktorý je vyhotovený ako platňový výmenník tepla a je odolný voči korózii, ako aj znečisteniu. Cez odparovací chladič 14, vyhotovený ako platňový výmenník tepla, prúdi vzduch, ktorý vchádza medzi platne cez vpust 15 a cez výpust 16 je odovzdávaný do okolia. Toto prúdenie zabezpečuje ventilátor 17.The cooling power that passes the vaporizer 6 to the third circuit 7 is fed by pump 8 to the storage tank 9. From the storage tank 9, the cooling capacity is transferred via the distribution system 12 to the cooling surface 11 via the distribution circuit 12. 13 is passed through an evaporator cooler 14 which is designed as a plate heat exchanger and is resistant to corrosion and contamination. Through the evaporator cooler 14, which is a plate heat exchanger, air flows between the plates through the inlet 15 and is discharged through the outlet 16 into the environment. This flow is provided by the fan 17.
Medzi vpustom 15 a platňami tepelného výmenníka tvoriaceho odparovací chladič 14 sa cez rozdeľovači systém 18 vstrekuje do prúdu vzduchu voda, čím sa zvýši chladiaci výkon vzduchu z tepelného výmenníka, a to na základe nízkej teploty odparovania. Na dopravu vody sa v prívodnom potrubí vody nachádza čerpadlo 19.Between the inlet 15 and the heat exchanger plates forming the evaporator cooler 14, water is injected into the air stream through the distributor system 18, thereby increasing the cooling capacity of the air from the heat exchanger, based on the low evaporation temperature. A pump 19 is provided in the water supply line to transport water.
Pri nasadení chladiaceho zariadenia s regulovaným výkonom sa môže vynechať medzizásobník 9. Kvapalinový okruh 7 vedie potom priamo k rozdeľovaciemu systému 12.The intermediate circuit 9 can be omitted when the controlled power cooling device is used. The fluid circuit 7 then leads directly to the distribution system 12.
V chladiacom okruhu chladiaceho zariadenia môže byť pred expanzný ventil 5 zaradený tepelný výmenník 25, cez ktorý prúdi voda, ktorá je potom privádzaná k rozdeľovaciemu systému 18. Týmto sa umožní ďalšie zlepšenie chladiaceho výkonu.In the cooling circuit of the cooling device, a heat exchanger 25 can be provided upstream of the expansion valve 5, through which water flows, which is then fed to the distribution system 18. This allows further improvement of the cooling performance.
Ďalej môže byť v chladiacom okruhu chladiaceho zariadenia pred vodným kondenzátorom 3 umiestnený tepelný výmenník 26, cez ktorý prúdi vzduch, vychádzajúci z odpaľovacieho chladiča M. Takto zvýšený odvod tepla zväčšuje celkový výkon zariadenia. Pritom sa využije tá okolnosť, že teplo z tepelného výmenníka 14 chladiaceho zariadenia 3, 13, 14 je ešte stále schopné prijať teplo, ktoré vychádza z toho istého chladiaceho okruhu chladiaceho zariadenia.Furthermore, a heat exchanger 26 can be placed in the cooling circuit of the cooling device in front of the water condenser 3, through which the air coming from the firing cooler M flows. This increased heat dissipation increases the overall performance of the device. The fact that the heat from the heat exchanger 14 of the cooling device 3, 13, 14 is still capable of receiving heat coming from the same cooling circuit of the cooling device is taken into account.
Prístroj, resp. zariadenie bude predovšetkým pracovať v troch rôznych stupňoch:The device, respectively. the device will primarily work in three different stages:
1) Ak je vzduch dostatočne chladný, nie je potrebné, aby chladiace zariadenie pracovalo, a tiež sa môže vynechať vstrekovanie vody v platňovom tepelnom výmenníku. Chladiaca1) If the air is sufficiently cool, there is no need for the cooling device to operate, and water injection in the plate heat exchanger may also be omitted. cooling
-5kvapalina prúdi potrubím 21, tepelným výmenníkom 23, potrubím 22 a cez odparovač 6 naspäť do medzizásobníka 9.The liquid flows through line 21, heat exchanger 23, line 22 and via evaporator 6 back to the intermediate tank 9.
2) Ak je teplota vzduchu taká vysoká, že voľné chladenie nepostačuje, môže sa chladiaci výkon zvýšiť vstrekovaním vody do odparovacieho chladiča.2) If the air temperature is so high that free cooling is not sufficient, the cooling capacity can be increased by injecting water into the evaporator cooler.
3) Pri ďalšom náraste teploty vzduchu a pri eventuálnej zvýšenej potrebe chladenia, pripojí sa chladiace zariadenie. Vstrekovanie vody do tepelného výmenníka 25 a tým podmienený pokles kondenzačnej teploty zlepší výkon chladiaceho zariadenia a redukuje tým spotrebu prúdu. Celkový výkon systému sa zvýši pomocou tepelného výmenníka 26.3) If the air temperature increases further and if there is an increased need for cooling, the cooling device is connected. Injecting water into the heat exchanger 25 and thereby condensing the condensation temperature will improve the performance of the cooling device and thereby reduce power consumption. The overall system performance is increased by the heat exchanger 26.
Chladiaca kvapalina 21 môže cirkulovať buď cez tepelný výmenník 23 a ďalej cez odparovač 6 chladiaceho zariadenia; alebo - prepnutím ventilu 24 - iba cez odparovač 6.The coolant 21 can be circulated either through the heat exchanger 23 and further through the evaporator 6 of the cooling device; or - by switching the valve 24 - only through the evaporator 6.
Všetky časti zariadenia, resp. prístroja, tzn. všetky časti chladiaceho zariadenia, odparovacieho chladiča 14 a riadenia a regulácie, ako aj všetky kvapaliny a vedenia vedúce prúd, sú kompaktným spôsobom uložené v jednej skrini 20. Skriňa 20 môže pritom pozostávať z viacerých ľahko prenosných jednotiek.All parts of the device, respectively. device, ie. all parts of the refrigeration device, evaporator cooler 14 and control and regulation, as well as all liquids and current-carrying lines, are compactly housed in one housing 20. The housing 20 may consist of a plurality of easily portable units.
Príklad 2Example 2
V ďalšom možnom vyhotovení je k vodnému kondenzátoru zaradený preklenovací obtok (BYPASS) 28, ktorý je súčasťou druhého kvapalinového okruhu 4, ktorý je čiastočne zaťažený, keď je otvorený ventil (trojcestný ventil) 27. Tým sa dosiahne kondenzácia iba vo výmenníku tepla (kondenzátore) 26. Pritom kompresor 2 pracuje vo viacerých etapách. To má tú výhodu, že kvapalinový okruh 4 nie je termicky zaťažovaný, takže sa zníži spotreba energie celého systému.In another embodiment, a bypass (28), which is part of the second fluid circuit 4, is partially connected to the water condenser, which is partially loaded when the valve (three-way valve) 27 is open. This only achieves condensation in the heat exchanger (condenser). 26. The compressor 2 operates in several stages. This has the advantage that the liquid circuit 4 is not thermally loaded, so that the energy consumption of the entire system is reduced.
