BASIC AIR CONDITIONING TRAINING SET
The experimental set includes a cooling unit, resistors for heating processes, and a humidification unit. The airflow of the used air is adjusted by a radial fan with adjustable speed. The duct system through which the air flows has a cross-sectional area of approximately 0.10 m². The air drawn from the atmosphere first enters a variable-speed centrifugal fan and then passes through the duct system. During heating operations, the humidification unit is activated to increase the moisture content. The resistors are engaged during heating, with the pre-heating resistor power at 1 kW and the final heating resistor power at 0.5 kW. These resistors heat the air. Information from temperature and humidity sensors can be monitored on the LCD screen. If cooled and dehumidified air is required to pass through the system, the cooling system is activated, and the cooling of the air passing through three ducts is achieved via the cooling unit and in-duct evaporator. While the cool and dry air passes through the duct, humidity and temperature sensors in this section perform measurements. If reheating of the air is desired, the final heating resistors must be activated. Before the conditioned air is released into the atmosphere, the air velocity is measured with an anemometer.
