Abstract:
1. A method, executed by one or more processors, for determining operating parameters for a humidity generator to generate humidity levels in an airflow, the method comprising: determining target density of an output airflow based on target output airflow temperature and target output airflow pressure; determining target relative humidity of the output airflow to achieve the target moisture content for the output airflow based on atmospheric pressure and ambient temperature outside the humidity chamber, and target density of the output airflow; determining an amount of water to be provided to an atomizing nozzle of the humidity generator based on 1) target moisture content for the output airflow, 2) target flow rate for the output airflow, 3) the target relative humidity of the output airflow, and 4) relative humidity of incoming air to the humidity generator; determining enthalpy required to evaporate water at the target output airflow temperature; determining power required to evaporate the water based on the enthalpy; determining heat required to achieve the target output airflow temperature based on 1) the target output airflow temperature, 2) the temperature of the supply air to the humidity generator; 3) target volumetric flow rate, and 4) heat capacity of air; determining total heat required based on 1) the heat required to achieve the target output airflow temperature and 2) the power required to evaporate the water based on the enthalpy; determining target atomizer nozzle air temperature for air provided to the atomizer nozzle of the humidity generator based on 1) the total heat required, 2) target flow rate for the output airflow, 3) the heat capacity of air, and 4) the temperature of the supply air to the humidity generator; and determining target air pressure to be supplied to the atomizer nozzle based on the target flow rate for the output airflow.
