47. Dehumidifier Calculation Worksheet Type of Dehumidifier Class 1 Class 2 Class 3 Class 4 Conventional Refrigerant 100 40 30 N/R Low grain Refrigerant 100 50 40 50 Desiccant 1 ACH 2 ACH 3 ACH 2 ACH Step 1 Calculate the cubic footage of your drying environment. L X W X H = CF Step 2 Define the class of water loss as described above. Step 3 Determine how many pints per day your humidifier removes from air based on the American Home Appliance Manufacturers test condition of 80 degrees F / 60% RH. Step 4 Using the chart above, calculate your total dehumidification needs. This can be calculated by dividing the factor into the total cubic footage of your drying area. This is based on the AHAM per 24 hours.

57. What does it really look like?

69. Is there mold here?……

70. Is there mold here?……

72. Eliminate one of these elements & mold won’t thrive! Food Source? Expensive and unlikely Temperature Zone? Bake the house? Moisture? All we need to remove is the excess!

75. Summary: Do You Know Everything? 1. Mold needs three things to grow: Food Source Temperature Zone Moisture 2. The three types of water sources are: Clean – Originate in the environment Gray – Drains or seepage Black – Sewage, rising water 3. New “Techie Terms”: Psychrometry Hygroscopic Microbial

76. Summary: Do You Know Everything? 4. The Four Drying Tools: Extraction Humidity Control Air Movement Temperature 5. The Difference Between Relative and Specific Humidity is: Relative Humidity indicates how close air is to saturation. Specific Humidity indicates how much moisture is in the air.
