Innovative sustainable dehumidification technology from InSpire Transpiration Solutions can help cultivators reduce heating, ventilation and air conditioning (HVAC) operating expenditures by as much as 30 to 50 percent.

Most commercial HVAC systems rely exclusively on a compressor, driven by an electric motor, to pressurize gas, exchange energy and reduce the temperature and humidity of the air in a given space.

InSpire’s sustainable dehumidification systems involve the use of a patent-pending multi coil water runaround loop to efficiently transfer energy before and after compressor-based dehumidification. The multi coil system reduces energy use and increases energy efficiency in two main ways:

    • Pre-Cooling: Cools the temperature of return air from the grow room to at or near the dew point prior to being dehumidified, without compressor energy 
    • Free Reheat: Heats the temperature of the air after dehumidification without compressor or other new energy to bring it back to the grow room set point 

      This allows cultivators to achieve environmental control with less compressor tonnage, resulting in HVAC energy savings of up to 50 percent.

      InSpire executes additional efficient system design practices, such as targeted CO2 enrichment, microclimate mitigation via canopy airflow optimization, and cloud-based room control.

      InSpire’s Chief Technology Officer, Robbie Batts, recently presented on this technology at the Resource Innovation Institute’s Indoor Agriculture Energy Solutions Conference.
