Here's the thing most people get wrong about ice rinks in hot places: the cold isn't your enemy. The humidity is.
Put a rink in Bangkok, Guangzhou, or Lima and the chiller doesn't just fight 35°C air — it fights the moisture that condenses on the slab, on the overhead structure, even inside the dasher boards. That condensate is what drives up energy bills, fogs the glass, and slowly eats your building. After 20+ projects in warm climates, I can tell you the rinks that hold up aren't the ones with the biggest chiller. They're the ones that got dehumidification and insulation right on day one.
Start with the dehumidification, not the chiller. In a humid city, dumping more cooling capacity on the problem is the expensive way to fail. A hazy rink in summer is almost always a dehumidification gap, not a cooling gap. We size the dehumidifier to the space's worst-case moisture load — people, resurfacing water, open doors — and treat it as a system with the chiller, not an afterthought. In a Foshan project where indoor humidity ran over 80% in July, a properly matched desiccant system cut the fog-on-glass complaints to basically zero within a week.
Insulation is where the money leaks out. A cold slab under warm, wet air is a condensation factory. If the under-slab insulation or the vapor barrier is thin, that moisture migrates in, the slab heaves, and you're repouring in a few years. We run vapor barrier and closed-cell insulation under every warm-climate slab, and we don't let anyone cut that corner to save a few percent on build cost. It's the difference between a rink that lasts ten years and one that needs a rebuild in three.
Size the chiller for 35°C+, not the brochure number. A chiller rated for a northern European winter won't hold ice in a Guangzhou summer. We design around peak ambient — 35°C minimum, often 38°C, plus the heat from people and lights. In Kunming, where the altitude changes everything, we had to re-verify the whole load calc because the standard curves didn't apply. Oversizing "just in case" is wasteful; undersizing is a warranty nightmare. Get the load calc done honestly.
If you're planning a rink somewhere warm, budget for dehumidification and insulation first, then the chiller. That order saves you more than any equipment upgrade ever will.
