DEVICE AND METHOD FOR HUMIDITY ESTIMATION
First Claim
1. A humidity estimation device connected with an air-conditioner, the device comprising:
- a charge airflow rate estimation unit that acquires operation control information of a charge fan of the air-conditioner and calculates an estimated charge airflow rate of the air-conditioner based on the operation control information of the charge fan and a preset fan differential pressure;
a charge air absolute humidity estimation unit that acquires a charge air temperature value of the air-conditioner and calculates an estimated charge air absolute humidity of the air-conditioner based on the charge air temperature value and a preset charge air relative humidity;
an indoor generated vapor amount estimation unit that acquires an indoor temperature value of a room that is an object controlled by the air-conditioner and calculates an estimated indoor generated vapor amount based on the indoor temperature value, the number of persons in the room and activity index values of the persons that are input; and
an indoor absolute humidity estimation unit that calculates an estimated absolute humidity in the room based on the estimated charge airflow rate calculated by the charge airflow rate estimation unit, the estimated charge air absolute humidity calculated by the charge air absolute humidity estimation unit and the estimated indoor generated vapor amount calculated by the indoor generated vapor amount estimation unit.

Abstract
A humidity estimation device connected with an air-conditioner includes a charge airflow rate estimation (CARE) unit, a charge air absolute humidity estimation (CAAHE) unit, an indoor generated vapor amount estimation (IGVAE) unit, and an indoor absolute humidity estimation (IAHE) unit. The CARE unit calculates an estimated charge airflow rate (ECAR) of the air-conditioner based on operation control information of the charge fan and a preset fan differential pressure. The CAAHE unit calculates an estimated charge air absolute humidity (ECAAH) of the air-conditioner based on a charge air temperature and a preset charge air relative humidity. The IGVAE unit calculates an estimated indoor generated vapor amount (EIGVA) based on an indoor temperature, the number of persons in the room and activity index values of the persons. The IAHE unit calculates an estimated absolute humidity in the room based on the ECAR, the ECAAH and the EIGVA.
