Ventilation Gaps in Korean Apartment Mining Setups

Apartment miners in Jeollabuk-do often place compact units beside balcony doors left ajar five centimeters for intake. Winter works; summer pulls humid outdoor air across dust filters that clog in weeks. We measure pressure at the intake grille when both door and window positions change.

Ondol-heated floors create subtle convection that pulls exhaust downward toward cold tile in winter months. A unit exhausting toward the floor can recirculate warm air under a low shelf. Raising the chassis 8–10 cm with open-frame stands breaks that loop without renovation.

Building management sometimes restricts visible duct hose on balconies. Internal acrylic baffles directing exhaust toward an upper corner, away from the intake face, reduced recirculation in three audits last year without triggering visual complaints.

Filter choice matters more than fan count. Fine mesh rated for pollen catches mining dust faster than operators expect. Coarse foam with weekly vacuuming outperformed dual auxiliary fans in two side-by-side tests on identical 0.058 TH/s units.

Before buying another fan, photograph your intake and exhaust paths during a load run with a smoke pencil or incense stick. Visible recirculation beats spreadsheet guesses every time.
