School District's VRF/ERV Retrofit Receives High Marks
The Lebanon Special School District (LSSD) in Lebanon, Tennessee, is one of the nation’s first school districts to retrofit conventional two-pipe classroom unit ventilators with combination VRF and ERV drop-in replacements.
LSSD’s Walter J. Baird Middle School recently performed a successful nine-classroom retrofit trial using SlimLine VRF/ERV unit ventilators manufactured by RevolutionAire. Each unit ventilator incorporates a combination of 3-ton VRF from Mitsubishi Electric and an enthalpy wheel for dehumidification. Consequently, the classrooms now comply with IAQ classroom codes under ASHRAE Standard 62.1.
