Heat exchange-type ventilation device

Abstract

Provided is a heat exchange-type ventilation device (1) comprising: an air supply blower including an air supply motor; an exhaust blower including an exhaust motor; an air supply path (7) through which air is sent to a room from outside by the air supply blower: an exhaust path through which air is sent from the room to outside by the exhaust blower: a heat exchange element provided at a position at which the air supply path (7) and the exhaust path intersect, the heat exchange element being configured to exchange heat between room air and outside air at the time of ventilation; and a current detector configured to detect a current flowing through the air supply motor. Using a controller (11), the heat exchange-type ventilation device controls the number of revolutions of the air supply motor. The air supply path is connected to a circulating air path (14) of unitary air conditioning (13), and the controller (11) changes the opening area of an airflow rate adjustment damper (15) provided in the air supply path (7) so that a current value of the air supply motor, the current value being detected by the current detector, falls within a predetermined range of a target current value.

Description

TECHNICAL FIELD[0001]The present disclosure relates to a heat exchange-type ventilation device.BACKGROUND ART[0002]As a conventional ventilation device configured to exchange heat between outside air and room air, there is known a heat exchange-type ventilation device that is installed in a building and configured to introduce outside air from an outside-air inlet port and supply the air to a room via a built-in heat exchange element (for example, refer to Patent Literature 1).[0003]Hereinafter, this heat exchange-type ventilation device will be described with reference to FIG. 11.[0004]FIG. 11 is a configuration diagram illustrating a top view of the conventional heat exchange-type ventilation device.[0005]As illustrated in FIG. 11, ventilation device body 201 is installed in an attic space or a ceiling space inside a building.[0006]Fresh outside air is introduced from outside-air inlet port 202, flows through built-in heat exchange element 203, and is supplied to a room via indoor...

Benefits of technology

[0012]The present disclosure solves the above-mentioned conventional problem, and an object of the present disclosure is to provide a heat exchange-type ventilation device capable of automatically determining the opening area of an airflow rate adjustment damper and thereby simplifying on-site installation. Note that simplified installation is merely an example, and a configuration having a feature except simplified installation is not limited to the heat exchange-type ventilation device capable of simplifying installation.

[0014]The present disclosure can provide a heat exchange-type ventilation device capable of simplifying on-site installation. Note that simplified installation is merely an example, and a configuration having a feature except simplified installation is not limited to the heat exchange-type ventilation device capable of simplifying installation. For example, a heat exchange-type ventilation device capable of enhancing the temperature adjustment efficiency of unitary air conditioning when connected to the unitary air conditioning can be provided regardless of simplified installation.

Problems solved by technology

However, this configuration has a problem that it is required to determine the angle (the opening area) of the airflow rate adjustment damper while measuring an airflow rate, and this makes on-site installation complicated.
