Remote fitted condensing unit
Hi Everyone.
If the condensing unit of a refrigeration system is remote fitted, how is it accounted in component selection?. For example a walk-in cold room with heat load of, say 4000 BTUH, has to be constructed either with the condensing unit attached to it or the unit 10 m (32.8 ft) away. If the condensing unit is away will it use the same condensing unit as that of the first case? Or how is it selected.
Thanks in advance
With regards
Rayin

Hi there,
The distance between components is used to size the pipes. With the correct length of the pipes and its fittings the pipe size must be calculated for pressure drop and oil return to the compressor.

Re: Remote fitted condensing unit
The size of the condenser will not change unless you have much higher or lower temperatures outside than inside.
It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Re: Remote fitted condensing unit
As previous posters already said, size is not dependent on distance, it depend on conditions of air which is around condenser.
If your condenser is designed for indoor usage with temperatures from 10°C to 30°C it cannot be used for outdoor where temperatures are from -5°C to 45°C or more.

Hi..Lana, Peter_1 and Nike,
Thank you for your prompt response. So from your rplies what I understand is, as far as ambient air condition is not changed, no need to change the condensing unit, for a remote fitted unit. Only thing the pipe line sould be sized in such a way that the total pressure loss should be in the permissible limit of design conditions. Am I correct?
Cheers

Indeed Rayin, just calculate your lines, that's all.
