Equipment Introduction

  • Blower airflow, current change experiment by system static pressure change

  • Indoor temperature and humidity change and filter, coil pressure loss practice by blower airflow change

  • Heating, humidification experiment

  • Humid-air chart automatic construction and materials analysis

  • DAQ program supply tools with that temperature, humidity (RH, AH), enthalpy, amount of the exchanged heat in each position can be measured in real time, and then saved by Microsoft Excel, so that saved data can be show and analysis by graph

Equipment Characteristics

  • Cycle composition :

  • Fresh air → mixed air → filter 1 → pre heater → pre cooler → humidifier → filter 2 → re heater → re cooler → blower → room → return air

  • Being practicable to operate on manual, temperature and humidity control with connecting by sequence and drawing a psychometric chart, displaying by digital sign data of temperature and pressure

  • Saving of data in every sec by excel file on PC

  • Experiment factors

  • - Cooling & heating capacity of room chamber
    - Bypass factor
    - Humidification
    - Dehumidification
    - Psychrometic chart
    - Temperature data
    - Being saved on every minute until 1,440 min as excel file after click the “SAVE”​
