Clearing.

There are hiIhI and freezer rooms known * in which Dder next to which a yerdampfer a known? Ise trained cold * The room air is circulated by a fan via the sensing surfaces. Fine plant © of this "known type is shown in Figure 1 and 2 in elevation and top view.

In the wall of the cold room © an evaporator 1 is attached, which is made of smooth Eöhr © & ader from Pvippenrohren © or from pipes with attached slats can exist in the usual price and through

an air duct is separated from the cold room * under the evaporator 1 there is a drip channel 5, while a fan 4 is arranged on the ceiling of the cooling room above the evaporator to "closed and transmits the generated cold or _s rather bimdeb DI® suströmende '' / arms of the circulated air and thereby cools the room in which the material to be cooled is mounted.

In the case of the conventional design, one calculates, in accordance with the air geocbnity, of 1 to 3w'bbo with heat transfer numbers that lie between 8 and 12 SE / sqm-st ~ ° a. The E ¹ UbIflache the evaporator must be verhältnisiaaßig large darait in being "led air velocity sufficient S & lt © transmission guarantees" does is. From then on, the humidity in the air is reflected in the form of soap at d © xi boring esp. Lame ilen down and the heat transfer is ssunehmead low, do tHe short Betriebsaeit the ^er »damper rest Laias" In Eühlanla ^, pn where the deepest Tempara * is tar above freezing, then thawing the frost on the cooling = areas from and collects as condensation in the feop channel 5,

In Ge freezing rooms η 7 / ould due to the low temperatures! Refrigerator © s of Seif not defrost "To Irotadem free% a make lühl'flSchen again Seif, the pilot at swan" de two are isolated and in them Provide air openings with flaps. Time after time, the air walls are now sealed off by means of the previous flaps after the freezer compartment} a mrcei? to the

Cooling system attached® line or a 7asse located above the cooling system; the sprinkler system is put into operation "and thaws the heat from the ears.

Usually the ICäXteanlagen work about 2o i <& n _es ifäh x & nß. The following 4o purple «sum defrosting» The Kalt® * = m & SöMÄ is practically used acidic about 1/3 of the 2®it (about 8-10 hours daily), during 2/3 of the tent (daily 16-14 hours ) are not required for defrosting. In order to achieve a specific medium output, the refrigerating machine must therefore be dimensioned about three times as large as if it were working continuously

If the steamer were to be made smaller in this known embodiment, the temperature in the steam tube would have to be lower in order to achieve the same output, so that more moisture or heat is deposited, which results in a very undesirable drying out of the goods to be cooled leads "space losses au high cooling * out aweiter Hachteil is that the Tsrdampfer completely ver especially in closely placed drilling * eist-j so that the system must be esetst iron time to time out of service ^ is eliminated again until the icing" This leads to harmful fluctuations in the temperature of the mill chamber. The aim is always to make the evaporator as robust as possible.

The Applicant has now erkaant these views as a technically based prejudice and decided for the first time, make the ^v erdampf © r much smaller al "so far 1blich m, Gleichseitiar he i? Ie Qeschwindi ^ ness of the circulated air as it flows through dei'Verdampf & rs considerably increased and used in "apielsweise Luftgeschwindigteiten tone 6-12ia / sec, Grundsätalich is according to the invention, the air velocity ss selected large _s that ate Reif T9"? aer condensation may fssbsetsen de ι _e HtÖiren an appropriately offset Anordniang the Terdampferrohre and narrow ;> uschnitt® mactxaa ^ ix ^ awische-n. the pipes allows you to achieve this goal even at lower air speeds.

This process has the part of the gate that due to the high air speed and the constant free of Heif pipes, Heat transition grinding according to today's experience of technology, depending on the air speed, up to 100 WE / q, m-Bt- ° O can be achieved * This results in a much smaller evaporator surface,

the

very significant savings in terms of material, space and Bersfc®!

As a result, when measuring the cold, mas slain © bra.iieh.fc also does not pay attention to the ge it for defrosting dee? er « cppfer ^ s to be taken * The lig ± tocs ± x | 5 & sensor system need only be dimensioned so large that the E3i3.temascM.ne with brochensia operation the required cooling capacity for maxtisal® loading in the Hochsoioiaer emeugtw In practice, need! » so one the refrigeration machine according to de ti · new experience build only a third to half ao large su as with the refrigeration system η? design type and the same performance »

So the ideal state of modern cooling is achieved - air that is as fat as possible at low temperatures, mad cosms - but the humidity that enters through diffusion of the walls and the humidity that comes in is opened as "frost or sweat" separates out during the natural humidity of the oil remains completely preserved.

The speed then drops from condensation water or soap and the air, which is saturated with air, flows through slits of the usual Kon® atrukticm to the cold room from _a
