How to maximise chiller efficiency

What about the temperature of the high flow? btw how much L/hr is yr low and high flow? Using 0.5" or 3/4" pipe?

Forgot liao about the high flow. The pipe should be 1/2" and the flow now is 1400l/h and high is 2500l/h and 4000l/h. For 2500 and 4000 i try put got no different leh.

its the 1/2" hose lah, its restricting the flowrate. I changed mine from 1/2" to 1" that made all the changes.

Hai got money wana change to Daeil 1h/p liao save all this trouble. But now very broke. Maybe wana mod the chiller change the heat exchange to TI and bigger hose connector.

Some chillers have a restrictor built-in so no matter how much pressure the pump exert, only XXXL/hr will go in & out. In this case, there is nothing you can do.

However, if your chiller comes with a screw-in hose adapter, you can change it to a larger diameter to accomodate higher flow.

thanx...i/m using Resun CL450. will try using a higher flowrate PH 2000l/hr....info u when the chiller explode

change the hose connector will do. Cheap and reversible mod.

Barra,

Recommended flowrate for Hailea 1/4hp chiller is max at 2000LPH.
Can I use a 3000LPH pump to run the chiller?

Last time i use CL450 with a floe rate of 1200l/h very good can try.

No harm to give it a try if u got the pump.

Thanx....currently using 1000l/h..gonna try 1000l/h vs 1200l/h vs 2000l/h upon old the old birdie recom

I got the pump. It's an Aquabee 3000 = 3000LPH.
Hmmm, will try it out soon. Hope nothing bad happens to the chiller
