Description
Przedmiotem wynalazku jest sposób i uklad cia¬ glego, zdalnego pomiaru stopnia oszronienia insta¬ lacji chlodniczych szczególnie parowaczy umiesz¬ czonych w komorach chlodniczych i inicjacji cyklu ich odszraniania.The subject of the invention is a method and a body system a complete, remote measurement of the frost degree of the installation refrigeration systems, especially evaporators refrigeration chambers and cycle initiation defrosting them.
Dotychczas znane sposoby okreslania stopnia oszronienia parowaczy polegaja na ocenie organo¬ leptycznej, lub/i pomiarze miejscowym grubosci szronu przy uzyciu przyrzadów opierajacych sie na zasadzie zwiekszania sie oporu wplywu powietrza przez dysze na oszroniona powierzchnie wraz ze wzrostem grubosci szronu, przeciecia strumienia swietlnego podajacego na fotokomórke przez na¬ warstwiajacy sie szron.Hitherto known methods of determining the degree the frosting of evaporators is based on the assessment of the organo ¬ leptic and / or local thickness measurement frost using instruments based on principle of increasing the resistance to air flow through the nozzles onto frosted surfaces with an increase in the thickness of the frost, the intersection of the stream feeder on the photocell through the na¬ layering frost.
Sposoby te znane sa ze zgloszen wynalazków P-165 821 i P-159 401. Wada tych sposobów jest miejscowy pomiar grubosci szronu, ponadto zabu¬ dowanie urzadzenia pomiarowego w parowaczu za¬ klóca przeplyw oziebionego powietrza a tym sa¬ mym nawarstwianie sie szronu w miejscu pomiaru.These methods are known from the notification of inventions P-165 821 and P-159 401. The disadvantage of these methods is local measurement of frost thickness, and also disturbed charging the measuring device in the evaporator chilled air flow and so on my frost build-up at the measurement point.
Celem wynalazku jest wyeliminowanie powyz¬ szych wad. Cel ten zostal osiagniety przez zasta¬ pienie pomiaru grubosci szronu — pomiarem prze¬ mieszczenia parowacza powstalego na skutek wzro¬ stu ciezaru spowodowanego osadzaniem sie szronu na jego powierzchni, przy czym parowacz moze byc zamieszczony lub postawiony na elemencie sprezystym. Wielkosc przemieszczenia jest propor¬ cjonalna do przyrostu ciezaru a tym samym do sredniej grubosci szronu na sciankach parowacza. , 2 Wielkosc ta jest mierzona znanymi przyrzadami.The object of the invention is to eliminate the above disadvantages. This goal has been achieved by the Frost thickness measurement foams - by the housing of the evaporator due to the increase in temperature one hundred weight due to frost on its surface, while the evaporator can be included or placed on the item resilient. The displacement is proportional rational to the weight gain and thus to average thickness of frost on the walls of the evaporator. , 2 This quantity is measured with known instruments.
W polozeniu odpowiadajacemu ustalonej granicznej warstwie szronu zostaje uruchomiony cykl odszra¬ niania który trwa do chwili calkowitego stopienia szronu na powierzchni parowacza, tym samym zmniejszenia jego ciezaru i powrotu do pierwotne¬ go polozenia.In a position corresponding to the predetermined limit frostbite, the defrost cycle starts A nanny that lasts until it is completely melted frost on the surface of the evaporator, thus reducing its weight and returning to its original condition its position.
Uklad urzadzen wedlug wynalazku jest uwi¬ doczniony w przykladzie wykonania na rysunku io przedstawiajacym parowacz w widoku z tylu. Pa¬ rowacz 1 jest zawieszony w komorze chlodniczej 2 na elementach sprezystych 3 wyposazonych w tlu¬ miki drgan 4 w sposób ograniczajacy mozliwosc przesuniec w kierunku innym niz mierzony. Czuj- nikiem przesuniecia jest opornik suwakowy 5 a wskaznikiem logometr 6. Cykl odszronienia jest uruchamiany przez zestyk 7.The arrangement of devices according to the invention is trapped given in the example of execution in the drawing io showing the steamer in the rear view. Bye the groove 1 is suspended in the cooling chamber 2 on the spring elements 3 equipped with a sleeve mica vibrate 4 in a way that reduces possibility move in a direction other than that measured. Feel- the displacement is represented by a 5a slide resistor 6. The defrost cycle is in the logometer actuated by contact 7.
Zaleta sposobu wedlug wynalazku jest mozli¬ wosc wskazan stopnia oszronienia w oparciu o przyrost ciezaru parowacza spowodowany osadza¬ niem sie szronu. Sposób ten eliminuje niedoklad¬ nosc miejscowego pomiaru grubosci szronu oraz umozliwia zdalne i ciagle przekazywanie wskazan, a takze umozliwia automatyzacje procesu chlod- niczego w oparciu o grubosc szronu na powierzchni parowacza, a tym samym zwiekszenie ogólnej jego sprawnosci.An advantage of the method according to the invention is possible the degree of frost indicated based on weight gain of the evaporator due to fouling no frost. This method eliminates the imprecision local measurement of frost thickness and enables remote and continuous transfer of indications, and also enables the automation of the cooling process nothing based on the thickness of the frost on the surface evaporator, thereby increasing its overall efficiency.
