    Altaqua grow room HVAC system Function with dehumidifying, cooling, heating and ventilation

    Altaqua Grow Room HVAC System provides intelligent control to ensure optimal growing conditions. It achieves the requirement of both humidity and temperature and controls the humidity level by setting a target, say from 50% to 60%RH, while providing cool air or heated air, say 70℉~80℉, which are the perfect climate conditions for growing. 

    we can tailor the optional function according to your requirement 

    Tailored Function for Options

    Altaqua grow room HVAC system Optional Function

    Altaqua Grow Room HVAC Features

    Refrigeration System

  • Our grow room HVAC system provides redundancy with scalable preformance for whole year-round reliable operation.
  • Multi-compressors design, with 2, 3, and 4 independent refrigeration circuits for choice. 
  • Independent refrigeration circuit and staged control by PLC. Since the circuits work independently, if there is one circuit fails, it will not affect the other circuit running.
  • TXV allows higher power efficiency and better temperature control
  • Reheat coil, hot gas reheat allows heat recovery
  • Air-cooled, water cooled for option allows heat rejection
  • Grow room hvac system

    Control System

  • We've developed the specific program with Siemens smart PLC and HMI, easy to extend and optimize the program.  
  • We have three control settings of operation, and you can choose any control setting on your grow room demands. You only need to set the target humidity and temperature, the machine will keep running by switching different function.
  • Control setting timing is design to use for your schedule. You could set the control setting according to different time schedule, this is perfect for your cycle with light on or light off. 
  • Optional function is easily to extended into control system, you can control the CO₂ level and air sterilization light for grow rooms.
  • Grow room hvac system - controlsystem

    Airflow System

    • We use EC fan motor to adjust the latent capacity and sensible capacity according to different growing stages loads requirements. 
    • Combo sensor, from the Switzerland. Easy set and reduce power consumption for precise humidity and temperature detection.
    • ERV 8 air filter allows filtration of tiny impurities, upgrading level for high standard is available.

    key factors for your grow room

    First, we must understand that the cannabis grow room is a complex environment. It hosts many living organisms, including plants, people and both bad and good microbes, as well as many processes that are constantly adding or removing energy from the overall ecosystem. Then, we need to consider the 5 key factors of your grow room.

    You also can learn more information from our grow book, get it now.

    Factor 1. Energy Balance

    Heat is generated by working employees, grow lights, fan motors, water pumps, CO2 burners, and other equipment running. Understanding how much energy will be in the system is key to calculate the capacity hvac system needs to balance the equation.

    Factor 2. Plant Density

    A dense canopy pairing with poorly circulating systems will create microclimates, which result in higher temperatures and relative humidity. It is also an important factor to decide how much capacity your grow HVAC system needs.

    Factor 3. Daily Watering

    Water transports nutrients through a plant and gives it a turgor. Almost all of the water you give to a plant’s roots comes out as water vapor via transpiration. As the plants grow and add biomass, more humidity will be created by the plants. It is important to know the amount of water that needs to be removed from the atmosphere.

    Factor 4. Project Layout

    Different grow rooms provide different floor square footage, walls, ceiling feet high, and grow racks. In order to maintain the unique consistent temperature and humidity level for grow room, it needs to build the right duct-work and airflow layout. Then it can deliver air and remove moisture from the right spots to ensure microclimate is eliminated.

    Factor 5. Future Expand

    We also need to consider the spare capacity for future phases grow, such as adding more plants and expanding your grow room size. Of course, it is necessary and important to minimize initial investment and operating expenses at the beginning.
