Humidity controlling ventilator

摘要

The present invention is directed to a humidity controlling ventilator which takes in air through the use of an air blowing fan, and controls the humidity of the taken air via an adsorption heat exchanger prior to supplying it to the room. In the invention, the air blowing fan is controlled so as to make an air volume flow rate approach a predetermined target volume flow rate. To do this, the invention calculates the fan's air volume flow rate based on a specific volume of air downstream of the adsorption heat exchanger and an air mass flow rate of the fan. The calculated value is fed to an air blow controller that is configured to control the fan such that the calculated air volume flow rate approaches the predetermined target air volume flow rate.

主权项

1. A humidity controlling ventilator that includes a humidity controlling member having an adsorbent and configured to bring the adsorbent into contact with air, and an air blowing fan provided downstream of the humidity controlling member to supply air to the humidity controlling member, and is configured to control a humidity of taken air using the humidity controlling member, and then supply the humidity-controlled air into a room, the humidity controlling ventilator comprising:
an air flow rate calculator configured to calculate an air volume flow rate of the air blowing fan based on a specific volume of air located downstream of the humidity controlling member and an air mass flow rate of the air blowing fan; and an air blow controller configured to control the air blowing fan such that the air volume flow rate calculated by the air flow rate calculator approaches a predetermined target air volume flow rate.
