Base case
- Rooftop electric vapor-compression cycle dehumidifier of 70 kW cooling capacity with a seasonal coefficient of performance of 3.0
- The percentage of time that the cooling process is operating is as follows:
- Electricity rate is $0.08/kWh, with capacity charges (demand charges) totaling around $1,000 annually due to the dehumidifier
- A gas-fired desiccant dehumidifier with a capacity of 17 kW and a seasonal latent coefficient of performance of 0.35
- End-use energy efficiency measures of 76% due to reduction of airflow to be cooled and dehumidified
- Fan electricity consumption is roughly the same as in the base case scenario
- Natural gas rate estimated at $8/GJ
- The desiccant dehumidifier costs $11,000 more than the base case system
