Refrigerant Distributor

Refrigerant Distributor

Refrigerant Distributor

(OP)
Hello everybody,

I would be extremely grateful if someone could help me.

I have been delivered a DX coil, working with a TXV valve.
I made some verifications and according to Sporlan tables it seems that the distributor selected is not correct, since it is referring to a capacity 30% higher than the effective of the coil.
It seems a design error.

In my opinion the equipment is not working suitably.
My question is: what can happen now ? Shall I change the distributor ?

Many thanks

RE: Refrigerant Distributor

Is the refrigerant flow correct for the coil selection? The coil may have been designed with a large quantity of feed tubes and thus your tons per tube is higher than the capacity of the coil. The designer may have used a custom nozzel to ensure correct pressure drop and flow rate. Is this system for a standard HVAC application or low temperature?

Dear Mr. DrRTU,

- no the flow is overestimated, since capacity is
- evaporating temperature is around 22F.

Please, have you got any suggestion ?

Many thanks

 

RE: Refrigerant Distributor

AO1958, you will have to provide a lot more information on the details of the system. You seem to be focused on the distributor. This is usually low on the list of issues. If the unit is a low / med temp. then 22F is not out of line. Is this system a conventional hvac comfort cooling application? You may have too much capacity on the condensing unit or low evap. airflow. A parker rep. will help check application of the TXV/dist./nozzle but be prepared to know the complete details of the system.
