Absorption chiller against common chiller + ice rink

[Welchita]

Hi Fellows!
Suppose a retroffing operation where a common DX chiller is selected to serve in an existingg installation, giving its sensive power at 7 - 12 ºC in the afternoon and during the night (low electrical rates period), working to charge a ice-rink at -6ºC ~ -5ºC for coping the next morning period (high electrical rates period) against an equivalent absorption chiller solution.
Some guidance is required, any hints, comments. Thanks.

This link speaks about some advantages and disadvantages.

so far, my experience is with 5⁰C min. temperature absorption chillers. LiBr+Water is definitely not an option for you. Check for Water+Ammonia systems.

The main prerequisite for absorption chillers is waste heat. If you have to generate heat to run an absorption chiller, strike it out, unless your power cost is too high.

On the operational front, my suggestion is to, consider a generous quantity of Aspirin, as a standard item, in your inventory list.

Good luck,

Do you dose your absorption chillers with Aspirin?

hmmm... yes, after I swallow all the LiBr.

We are back to hieroglyphs, ironically.

Are you looking for an energy efficient solution? There are also options such as those by CIMCO Refrigeration and ICE KUBE systems, that reject heat from the ice making plant to various low temperature heating solutions. These systems also incorporate thermal energy storage systems to reduce peak demand.

Ice Kube uses heat pumps for ice production, either georthermal or via a cooling tower loop

Hi Fellows!

Thank you so far for your replies!
I must say we are working here on office-building and there is not any spare/waste heat. In the absorption chiller option we should analyse a direct gas-fired heat source chiller unit.
