Mushroom AC Plant & Climate Control for Grow Rooms
An AC mushroom farm is a farm whose every grow room has its own Daikin packaged DX unit. MushroomWale engineers that AC plant for mushroom grow rooms — Daikin packaged AC, AHU systems, ducting, misting, and digital controls. ±1°C temperature stability for year-round Agaricus bisporus production. From ₹2.5 lakhs/room.
The short answer
What Is a Mushroom AC Plant?
A mushroom AC plant is the room-by-room cooling most Indian button mushroom farms run on: one Daikin (or Carrier) packaged DX unit per grow room — 6 TR for an 18×30 ft room, 8 TR for 18×40, 10 TR for 18×60 and 12 TR for 18×70 — with a ductable evaporator, humidification and fresh-air control. It costs ₹2.5-5 lakh per 18×40 ft room installed, and MushroomWale's engineering study finds it the lowest capital-plus-ten-years-of-electricity option up to 1,000 kg/day; chilled-water and ammonia plants take over at larger scale.
The short answer
What Climate Control Does a Mushroom Room Need?
A mushroom grow room needs precision control of four parameters: temperature (16–18 °C in cropping for button mushrooms), relative humidity (85–90%), CO₂ (under 1,000 ppm from pinning on) and fresh air exchange. MushroomWale does it room by room: a Daikin packaged DX unit per room with air handling and ducting, high-pressure misting, exhaust with fresh-air dampers, and a controller.
Climate Control Components
Daikin Packaged AC
Energy-efficient inverter technology. Corrosion-resistant coils for high-humidity operation. Precise ±1°C control.
Grow room + AC packagesAir Handling Unit (AHU)
Integrated cooling, heating, humidification, and filtration for commercial farms. Centralized climate management.
Misting & Fogging
70-100 bar high-pressure misting for 10-15 micron droplets. Even humidification across all rack tiers without wetting.
Ducting System
Insulated perforated ducting for uniform air distribution. Custom-designed to prevent hot/cold spots across racks.
PUF panel insulationDigital Controllers
Temperature, humidity, and CO₂ controllers with data logging. Optional Naayom automation runs every stage from one controller per room.
Exhaust & Ventilation
Motorized exhaust fans with fresh air dampers. CO₂ sensor-based ventilation scheduling for optimal growing conditions.
