HVAC, AIR HANDLING EQUIPMENT

KTE-1000AHU

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”
