Refrigerant Compressor is Sweating

[kaskiris]

A certain refrigerant compressed air dryer during operation the refrigerant compressor is sweating**(is always wet) and cause often a short circuit and**the
protection device (RCD) energised .**Usualy this is caused if a liquid refregerant is returning to the compressor.

Can you comment please?

Hi there,
You have to describe your system more than that. What is the actual application of your system?
What kind of evaporator is there?
Is there a TEV or cap tube?
and many more questions......

Give us more info.
Cheers

It humid ambients, it is perfectly normal that the suction side of the compressor is sweating. It is not normal that the condensate drips over an electric component and trips it. Just protect the device by making sure any more drop drips over the electric parts.

You need to check that the air flow through the drier is as normal.

Some air drier have a hot gas bypass, or similar, to control the load of the evaporator. You need to monitor the temperatures through the system so that the system operation can be analysed properly.

Could it be that your getting liquid back to the compressor. check your bulb if you have an x-valve and make sure is is all the way down in the well

Hi B4R and welcome to the forum.

I am very happy that we are working in the same field. The dryer is Friulair - Italy- type DFR18 -
Thanks

Dear all,

Can you please help me?

I have to know about the specific heat of MILK KHOA to work out a cold storage calculation.

Kindly reply to my personal ID :tjk2007@gmail.com

Thank you Very much.

I have to know about the specific heat of MILK KHOA to work out a cold storage calculation.

It is off topic in this thread. I don't know what KHOA is, but I assume is milk, like any other cow milk

Composition of milk:
87.3 % water
3.9 % milk fat
8.8 % solids-not fat
3.25 % protein ( ¾ casein)
4.6 % lactose
0.65 % minerals (Ca, P, citrate, Mg, K, Na, Zn, Cl, Fe, Cu, sulfate, bicarbonate)
0.18 % acids (citrate, formate, acetate, lactate, oxalate)
enzymes, gases, vitamins
Milk Fractions:
Plasma (skim milk or milk minus fat)
Serum (plasma minus whey [casein micelles])
SNF (solids-not fat [proteins, lactose, minerals, acids, enzymes, vitamins])
Total Milk Solids (fat plus SNF)

Physical Properties of milkfat: density at 20° C is 915 kg/m3 refractive index (589 nm) is 1.462 which decreases with increasing temperature solubility of water in fat is 0.14 % at 20° C and increases with increasing temperatures thermal conductivity is about 0.17 J/ msK at 20° C specific heat at 40° C is about 2.1 kJ/ kg K electrical conductivity is < 10/ohm cm dielectric constant is about 3.1
