Working principle

1. 
   Flat constant control system adjust the temperature and humidity, using PID to control SSR, the heating and humidification of the system is equal to the heat loss.
   
2. 
   The temperature signal from the dry wet bulb is output to I / 0 plate by A/D conversion input controller CPU and RAN, I/0 gives the instruction, To make air supply system and refrigeration system work, at the same time, the PID control SSR or heating SSR work, or humidifying SSR work, Make the heat and wet energy through the air supply system uniform the test box, so as to achieve the function to constant adjust the temperature and humidity.
   

Machine require equipment

This part shall be in charge of the buyer and prepared before use the equipment!
power: AC220V notice: the range of voltage frequency variation to ensure the performance of the equipment: voltage±5%; frequency±1% !
Humidification water: must the pure water or distilled water (The first time must be above 20L)or the water that conductivity is below 10us/cm。
notice: Make sure the water is cleaner and better, and prohibit the use of underground water!

   Installation site and installation method
   
   1. 
      The installation location should consider the thermal efficiency of the machine and easy to check and maintain.
      
   2. 
      The bottom of the machine is the freezing system, and the heat is larger, So at the time of installation, The machine body should be at least 60 cm away from the wall and other machines, For ventilation
      
   3. 
      Set on flat, unvibrating groundInstall the four horizontal feet at the bottom of the fuselage, make the machine counterbalance , In order to the inner box dewatering and prevent abnormal noise(please use the gradienter to check)
      
   4. 
      Avoid direct sunlight and maintain indoor air circulation.
      
   5. 
      Please place the machine in a separate space, not to be placed in the field of public or near by flammable, explosive, perishable chemical, In case fire and personal injury occur when a failure occurs.
      
   6. 
      Shorten the electrical supply and drain lines as much as possible.
      
   7. 
      Avoiding place the machine at the place that dirty or dust. that will make : The machine is slow to cool down or Can't meet the requirements of low temperature and the control cannot be very stable for temperature and humidity, The surrounding temperature and humidity should be maintained in 10 ℃ ~ 30 ℃; can only get the best and most stable transport between 70 or minus 10%RH.
      
   8. 
      No sundries are allowed at the top of the fuselage, Avoid injuries and damage to property when the weight fall.
      
   9. 
      Do not use electric box, electric wire or motor as the driving force, Prevent electrical box, electrical damage, Loose or cause accidental failure.
      
   10. 
       Furnace maximum gradient should be under 30 °, In the meantime, the furnace must be firmly in place to prevent the body from falling, damaging or damaging the human body and property.
       
   11. 
       The positioning machine needs to be shifted again, Please take back the four horizontal feet of the machine and then move, balance the machine again ,avoiding damage the machine .
