Swimming pools
Pool halls exhaust warm, moisture-laden air constantly. Without recovery, that latent heat is lost. An enthalpic rotary wheel or membrane plate unit recovers both temperature and humidity, slashing pool heating and dehumidification bills 40-60%.
Gyms and fitness centers
High occupancy means high fresh-air demand and high moisture. Sensible plate recovery handles the heating-season load; enthalpic cores help in cooling seasons.
Ice arenas
Compressor heat is abundant but often wasted. Capturing it via air-to-air or air-to-water recovery can offset arena heating and even melt snow.
Design notes
- Corrosion resistance matters: pool and arena air is aggressive. Specify epoxy-coated or polymer cores.
- Control humidity to avoid condensation on structure.
- See pressure-drop guidance to keep fan power in check.
Payback
With 24/7 loads and high humidity, these facilities frequently recover capital in 2-3 years. Start with a heat-load audit, then size to peak occupancy, not the empty building.
Ventilation loads drive the case
Pools, gyms, and arenas share one trait: very high fresh-air and exhaust rates relative to floor area, because of occupancy, moisture, and chlorine or body odors. That high and continuous airflow is exactly what makes recovery attractive. The more air you move, the more energy a given effectiveness recovers. Sizing should follow peak occupancy and activity, not the empty-building condition.
Humidity control is the design center
In pool halls the priority is removing moisture to protect the structure and keep comfort, so the recovery core is part of a wider dehumidification strategy. An enthalpic wheel or membrane plate that returns latent heat to the incoming air reduces both the heating and the dehumidification load. Set the control to hold indoor relative humidity in the target band rather than chasing a single temperature.
Corrosion and material choice
Pool and arena air is chemically aggressive, so core material matters more than in an office. Epoxy-coated or polymer cores resist the chlorine and cleaning-chemical environment far longer than bare aluminum. Specifying the right material up front avoids early replacement and keeps pressure drop stable.
Frequently Asked Questions
Why recover heat in pool halls?
Pool halls exhaust warm, moisture-laden air constantly. An enthalpic wheel or membrane plate recovers both temperature and humidity, cutting heating and dehumidification bills by 40 to 60 percent.
Which exchanger suits gyms and arenas?
Sensible plate recovery for the heating season and enthalpic cores for cooling seasons, with corrosion-resistant epoxy or polymer cores for the aggressive air.
How should I size recreation-facility recovery?
Size to peak occupancy and activity, not the empty building. Continuous round-the-clock loads support a fast payback.
What payback do these facilities typically see?
Given high humidity and 24/7 operation, many recover capital in 2 to 3 years.
