Te mahi o nga waahanga nui o te horoi maroke

1..

Ko te pouaka whakamātao ko te ngakau o te punaha whakamahana, me te nuinga o nga kohinga i tenei ra ka whakamahi i nga kohinga ututmetic. Raising the refrigerant from low to high pressure and circulating the refrigerant continuously, the system continuously discharges internal heat to an environment above the system temperature.

2..

The function of the condenser is to cool the high-pressure, superheated refrigerant vapor discharged by the refrigerant compressor into a liquid refrigerant, and its heat is taken away by the cooling water. Ma tenei ka taea e te tuku whakamahana te haere tonu.

4. Ko te Valve ValValtional Valve (Capillary)

Ko te huringa whanaketanga waikawa (capillary) te tikanga throttislism o te punaha pouaka whakaata. I roto i te whakamahana pouaka whakamātao, ko te toha o te kaihopu o te kaiwhakawhitiwhiti me te whakahaere i te mana whakahaere i roto i te huarahi throtting. Ko te miihini throtting e taea ai te pouaka whakamātao kia uru ki te epiporator mai i te pāmahana nui me te wai nui.

5. He tino wera

The vast majority of refrigeration dryers have a heat exchanger, which is a heat exchanger that exchanges heat between air and air, generally a tubular heat exchanger (also known as a shell and tube heat exchanger). The main function of the heat exchanger in the refrigeration dryer is to “recover” the cooling capacity carried by the compressed air after being cooled by the evaporator, and use this part of the cooling capacity to cool the compressed air at a higher temperature carrying a large amount of water vapor (that is, the saturated compressed air discharged from the air compressor, cooled by the rear cooler of the air compressor, and then separated by air and water is generally above 40 °C), thereby reducing the heating load of the refrigeration and drying system and achieving the purpose of saving energy. On the other hand, the temperature of low-temperature compressed air in the heat exchanger is recovered, so that the outer wall of the pipeline transporting compressed air does not cause “condensation” phenomenon due to the temperature below the ambient temperature. In addition, after the temperature of the compressed air rises, the relative humidity of the compressed air after drying is reduced (generally less than 20%), which is beneficial to prevent the rust of the metal. Some users (eg with air separation plants) need compressed air with low moisture content and low temperature, so the refrigeration dryer is no longer equipped with a heat exchanger. Mai i te mea kaore e whakauruhia te whare o te wera, kaore e taea te hangai te hau makariri, a ka nui te maha o te wera o te evaporator. In this case, not only does the power of the refrigeration compressor need to be increased to compensate for energy, but also the other components of the entire refrigeration system (evaporator, condenser and throttling components) need to be increased accordingly. From the perspective of energy recovery, we always hope that the higher the exhaust temperature of the refrigeration dryer, the better (high exhaust temperature, indicating more energy recovery), and it is best that there is no temperature difference between the inlet and outlet. But in fact, it is not possible to achieve this, when the air inlet temperature is below 45 °C, it is not uncommon for the inlet and outlet temperatures of the refrigeration dryer to differ by more than 15 °C.

Te tukatuka hau hurihuri

Te tiaki me te tirotiro: Kia mau ki te pāmahana o te reanga o te pouaka whakamātao i runga ake i te kore.

Hei whakaiti i te pāmahana rangi kōpeke, me iti rawa te pāmahana o te pouaka whakamātao. When the refrigeration dryer cools the compressed air, there is a layer of film-like condensate on the surface of the fin of the evaporator liner, if the surface temperature of the fin is below zero due to the decrease in the evaporation temperature, the surface condensate may freeze, at this time:

A. Due to the attachment of a layer of ice with a much smaller thermal conductivity on the surface of the inner bladder fin of the evaporator, the heat exchange efficiency is greatly reduced, the compressed air can not be fully cooled, and because of the insufficient heat absorption, the refrigerant evaporation temperature may be further reduced, and the result of such a cycle will inevitably bring many adverse consequences to the refrigeration Pūnaha (penei i te "Whakatuturu wai");

4. Ka mau tonu nga punaha me nga punaha tuitui

Te take whakahaere

1 Tirohia i mua i te pupuhi

1.1 Ko nga urupa katoa o te punaha whatunga putorino kei roto i te ahua tuuturu;

1.3 Ko te pouaka miihini teitei me te pouaka whakakakahu iti te mita o te kohukohu i runga i te papa papatohu he tohu, he rite tonu;

1.4 Tirohia te huringa tuku hiko, e kore e neke atu i te 10% o te uara reanga.

2 Tukanga Poot

2.1 Ka pēhi i te pātene Tīmata, ka whakaroa te hoapaki AC mo te 3 meneti ka tiimata, ka tiimata, ka tiimata te tiimata o te pouaka whakamātao;

2.2 Observe the dashboard, the refrigerant high-pressure meter should slowly rise to about 1.4Mpa, and the refrigerant low-pressure meter should slowly drop to about 0.4Mpa; I tenei wa, kua uru te miihini ki te ahua mahi noa.

2.5 Tirohia mehemea he mea noa te wai o te wai o te wai aunoa;

2.6 Tirohia nga ahuatanga mahi o te whakamaroke i nga wa katoa, tuhia te kaha o te hau me te pehanga o te putanga, te iti me te iti o te pehanga o te waro makariri, aha atu.

3.1 Katihia te Valle Air Valve;

3.2 Katihia te Valle Air Felve;

3.3 Patohia te pātene aukati.

4 nga tiakitanga

4.1 A kore e rere mo te wa roa kaore he uta.

4.2 Kaua e tiimata te pouaka whakamātao haere tonu, a, ko te maha o nga tiimata ka mutu mo ia haora kaore e nui ake i te 6 nga wa.

4.3 kia pai ai te kounga o te toha hau, kia mau ki te ota o te tiimata me te aukati.

4.3.1 Tīmata: Kia rere te horoi mō te 3-5 meneti i mua i te whakatuwhera i te hau hau, i te waha ranei.

4.10 Te Mahi Whanui i te wa e whakahaere ana koe i te "Tīmata" me te "aukati" pātene

4.11 The air-cooled refrigeration dryer cooling fan is controlled by the pressure switch, and it is normal for the fan not to turn when the refrigeration dryer works at a low ambient temperature. I te mea ka piki haere te pehanga teitei, ka timata te kaiwhaiwhai.
