Pool Hall Recovery
Swimming pools and leisure centers exhaust warm, saturated air that, if unrecovered, represents both lost energy and a humidity problem that damages building fabric. Enthalpy recovery captures both the heat and the moisture in that exhaust.
Why Enthalpy
Because pool exhaust is laden with water vapor, a sensible-only plate core leaves most of the energy in the vapor. An enthalpy wheel or membrane core recovers latent load as well, cutting both heating and the cooling or dehumidification needed to handle incoming air.
| Need | Best core |
|---|---|
| Heat only | Plate |
| Heat and humidity | Enthalpy wheel or membrane |
Material Selection
Pool air is corrosive due to chloramines, so the core and casing must use compatible materials such as polymer plates or coated metals, with accessible cleaning to manage buildup. Specifying for the environment protects the recovery investment.
Outcome
Leisure centers report large cuts in heating and dehumidification energy, with payback commonly under three years given the high humidity load. The same recovery reduces condensation on windows and structure, lowering maintenance and extending building life.
Sizing and Selection Checklist
| Factor | Choice |
|---|---|
| Humidity load | Enthalpy or membrane |
| Corrosion | Polymer or coated metal |
| Cleaning | Accessible exhaust side |
| Drainage | Condensate managed |
Common Pitfalls
Leisure centers sometimes use a plain plate and miss the latent saving that dominates pool loads. Others specify bare metal in chloramine air and watch it corrode. Forgetting condensate drainage damages the enclosure the recovery was meant to protect.
Frequently Asked Questions
Why not a simple plate core?
Because pool exhaust is saturated, a plate recovers little of the energy held in vapor; an enthalpy or membrane core recovers the moisture too.
Which material lasts?
Polymer or coated metals resist chloramine; with accessible cleaning they hold recovery for years in the wet environment.
Summary
Pool recovery with the right enthalpy core and corrosion-resistant material cuts heating and dehumidification energy and protects the building.
Next Steps for Pool Recovery
Confirm the latent load first, then choose an enthalpy core and the right material so the saving is real and the hardware lasts.
- Verify the humidity ratio to justify an enthalpy rather than plain plate core.
- Select polymer or coated metal for chloramine resistance.
- Ensure condensate drainage and accessible cleaning of the exhaust side.
With those set, the core cuts heating and dehumidification energy and protects the building fabric.
Cost, Payback and Upkeep
Pool recovery centers on an enthalpy or membrane core plus corrosion-resistant materials, so capital is a little higher than a plain plate but the latent recovery is what pays. The payback is the large heating and dehumidification energy a pool exhaust carries.
- Capital: enthalpy or membrane core in polymer or coated metal.
- Payback: commonly under three years in leisure and aquatic centers.
- Upkeep: condensate drainage and accessible cleaning of the moist exhaust side.
Correctly specified, the same recovery also reduces structural condensation and maintenance.
Key Takeaways
Pool recovery should be enthalpy-based because the exhaust is saturated: choose a wheel or membrane core for latent recovery, specify chloramine-resistant material, and ensure condensate drainage with accessible cleaning. The same core cuts heating and dehumidification while protecting the building.
- Enthalpy or membrane core for latent recovery.
- Corrosion-resistant material for chloramine air.
- Drain condensate and clean the exhaust side.
