Facts

Myth 05 Source Capturing chemicals eliminates the ability for heat recovery on the exhaust air.​ Fact 05 After source capture, the exhaust air stream is full of energy and should be considered for heat recovery.

Myth 04 Adding more Outside Air than the code requires leads to better space conditions.​ Fact 04 Adding more OA results in unnecessary space condition fluctuations. You can expect conditions that are too dry in the winter and too warm and humid in the summer.​

Myth 03 Using more Outside Air removes the need for compressor-based dehumidification.​ Fact 03 Using more outside air than code requires dramatically increases your operating costs as it requires moving and conditioning large volumes of OA. Optimized compressor operation nets you a 1/3 reduction in your energy costs and provides yearound comfort.​

Myth 02 Dilution is an effective means to ensure better IAQ.​ Fact 02 A facility can be operating in 100% OA mode and still have IAQ issues, especially ifair distribution is not well designed. Chloramines are heavier than air and tend to sit on the water surface. The dilution approach requires the chloramine layer to … Read more

Myth 01 Using more Outside Air removes the need for compressor-based dehumidification.​ Fact 01 The weather conditions in most parts of the country are not suitable for a 100% outside air approach. Over 90% of all OA systems have compressors added to ensure conditions are not too warm or humid year-round.
