Die  kompressor van my karavaan se yskas op opgepak en moet vervang word.

Terwyl die yskas nou uit sy “kas” is, het ek gedink om ‘n extractor fan te installeer, dié wat in ‘n rekenaarkas gebruik word, 80mm of 120mm, moet nog kyk of daar plek vir ‘n 120mm fan is.

Die vraag is nou of dit werklik nodig is om ‘n fan (of twee van 80mm) te installeer.

Moet ek net bo installeer of ook onder waar die kompressor is, onder lug van buite insuig en bo die warm lug uitblaas?

Het enige iemand ondervinding hiervan? My karavaan is ‘n 2011 Gypsey Regal en dit het “Eco1” yskas & vrieskas.

Hi Johan ja installeer bo, dit werk baie goed, en het n defnitiewe invloed op werking van yskas, veral in baie warm toestande .Dit is nie nodig vir onder, jy wil net die warm lug verwyder wat opstyg na bo .Kyk net dat hy wel die lug uitblaas, maw dat hy regte rigting om draai .

My karavaan yskas het nou Desember baie beter verkoel deur 'n 80mm fan by onderste inlaat te sit en hom teen die plaat agter te laat waai.. Uiteindelik het myne elkgeval ook opgepak alhoewel die kompressor nou nog loop maak die yskas nou glad nie koud nie, Het ander yskas gekoop wat nou A+ rating het en loop wragtag op minder krag as 'm 12V yskassie. Baie impressed en het nou baie minder sonkrag nodig om yskas koud te hou.

Ek het vir my ook aan die bokant 'n 125mm waaier van 230V ingesit. Pasop vir 'n te klein waaier gebruik. Waaier het aparte prop direk langs die yskas sodat ek dit in die nag kan afskakel. As mens 'n gat in die wa se muur wil maak sal ek die badkamer tipe waaiers gebruik wat ba buite waai want hulle is baie stiller.

Die Classique het die waaiertjie standaard in met 'n skakelaar aan die kant om hom in die aand af te sit as dit so stil raak.  Al wat hy doen is om te help om die warm lug vinniger te laat sirkuleer.

Die lae spanning waaiers van rekenaars werk puik dis nou as jou karavaan 'n 12V battery in het.  Indien nie kry 'n tweedehanse rekenaar PSU en plug die waaiertjie daarin.

Johan,

The fans were especially usefull for the older absoption type fridges. The purpose of the fan is to improve the poor airflow due to poor caravan design. I would doubt that you would see any major improvement fitting fans as the ECO1 is arteady an efficient fridge. We always camp in the Kruger over December with no problems.

If you are really determined to do something then IMO you would be better off altering the venting in the fridge enclosure. This is passive, requires no electrical work and improves the venturi effect of the fresh air passing over the cooling fins.

Send me a PM with your email address and I will send you the article I wrote published in the Caravan and Outdoor magaine some years ago. This will show you the venting problems we exprienced on absorption fridges and the fixes. This venting theory will apply equally to you.

If you chose to fit fans we noted that the are more efficient when fitted to the outside of the vent, pulling ar through the vent rather than blowing air into the slats of the vent. I made a temperature controller so that the fan automatically altered the speed as the ambient temperature increased and then switched off when the ambient temperature dropped below 30 if I remember correctly. 

One too many wasted sunsets, one too many for the road.

In fact you can buy fans with a temp sensor already fitted, they sort of "tick over" and as the temp rises they turn faster. Fitted two to my Fleetline's battery charger's heatsink some years ago and they work a charm.
