Chiller Testing Prior to Tie-in to Existing System

[homerphish]

I've got 5 brand new Trane Centrifugal chillers in a new central plant that we've constructed for an office building. I have to do a majority of the chiller commissioning prior to tying the new system into the existing chilled water riser. Does anyone know of any ways to simulate building load? I would use the new heating hot water system that we've installed, but I can't fire the boilers due to an AQMD moratorium on new boiler permits.

This may help you

Moratorium with SC-AQMD permits was recently lifted.

imok2,

The website you refer to seems to be only for computer simulations of building loads for the purpose of chiller selection and design. Our chillers are already installed. I need to somehow simulate the building load on the chilled water system for our commissioning and functional testing.

Thanks, though.


KiwiMace,

The moratorium has been conditionally lifted, but this requires purchase of several million dollars worth of ERC's. The owner isn't sure they want to do that yet.

Thanks

how about feeding the chilled water circuit of one into the condenser circuit of the other. You will still need to get rid of a bit of heat though manageable through the cooling tower perhaps.

Would this be a consideration?

Trailer and skid mounted hydronic heating boilers with control hoses & circulating pumps. Pre-piped and wired for easy connection to your existing system

Can you use the new chillers to cool the condenser water for existing system chillers? You'd need to make sure the condenser water was clean.
