Full Description
Although counter intuitive, using a heat pipe air-to-air heat exchanger in summer for both sensible cooling (Indirect) and adiabatic cooling andhumidification (Direct) of the outdoor air in an arid climate can reduce peak refrigeration tonnage while exceeding Standard 62.1 outdoor air ventilationfor a Natatorium. The final stage of cooling required in warm weather is furnished with a DX refrigeration component with the condenser coil located inthe building exhaust air stream for a higher Energy Efficiency Ratio (EER). Pool water heating costs are reduced when the dry outdoor air in summer ishumidified and cooled by the direct evaporative cooling media.
Heat recovery in cold ambient conditions allows the system to exceed minimum code outdoor air flow requirements into the Natatorium to dilute andremove Chloramines and maintain a better Indoor Air Quality (IAQ) in the pool enclosure without an excessive amount of reheat energy.
This case study will analyze the Aquatic Center project installed in Dublin, California.
