In order to efficiently exchange indoor air and outdoor air, to reduce power consumption, and to reduce discomfort to a user, damper, which switches between a heat exchange exhaust air path and a normal ventilation air path, is provided in an exhaust air path. In addition, a discomfort index is calculated from detection results of indoor temperature sensor provided on indoor-side inlet and outdoor temperature sensor provided on outdoor-side inlet. Further, controller, which switches between the heat exchange exhaust air path and the normal ventilation air path so as not to cause discomfort to the user, is provided to control damper.

Supply and exhaust ventilation device

A total heat exchange device includes: a fan for the exhaust air path which directs air from an indoor exhaust port to an outdoor discharge port through an exhaust air path; another fan for intake air path which directs air from an outdoor suction port to an indoor intake port through an intake air path; and a heat exchange element for exchanging heat between air passing through the exhaust air path and air passing through the intake air path. Also included is a temperature detector for detecting an outdoor temperature and a controller configured to perform a heat exchange mode in which heat is exchanged between air passing through the exhaust air path and air passing through the intake air path or a defrosting mode in which frost on the heat exchange element is thawed, in accordance with the outdoor temperature detected by the temperature detector.

Total heat exchange device and controlling method of the same

A heat exchanging ventilation device includes supply air blower (); exhaust air blower (); a supply air blowing passage through which air to be delivered to indoor from outdoor by supply air blower () passes; a exhaust air blowing passage through which air to be delivered to the outdoor from the indoor by the exhaust air blower passes; heat exchange element () disposed at a position where both the supply air blowing passage and the exhaust air blowing passage pass and exchanging heat between air delivered by supply air blower () and air delivered by exhaust air blower (); supply air damper () provided on supply air inlet () side of the supply air blowing passage; exhaust air damper () provided on exhaust air outlet () side of the exhaust air blowing passage; and circulation damper () provided at boundary portion () which separates the supply air blowing passage and the exhaust air blowing passage from each other.

Heat exchanging ventilation device

A heat exchange device includes: a case, a fan provided inside the case and having a fan air outlet and a fan air inlet, a heat exchange element provided inside the case, a case air port formed in the case, and an adapter connected to the case air port at one end thereof, the adapter including more than one pipe connecting portions with different diameters, the pipe connecting portion closest to the case air port being a first pipe connecting portion, the pipe connecting portion farthest from case air port being a second pipe connecting portion; the diameter of the first pipe connecting portion is larger than the diameter of the second pipe connecting portion, and a thermal insulation component is provided in the adapter and has an air passage therein for passing air therethrough. The disclosure is advantageous in preventing occurrence of condensation and improving product safety.

Heat exchange device

A ventilating device includes a frame forming an outer contour, an airflow path formed by a flowing of air inside the frame, and a plurality of orifices configured to measure a static pressure in a chamber where the airflow path is located, wherein at least one orifice of the plurality of orifices is further configured to drain water out of the frame. In the present disclosure, the orifice for static pressure measurement is provided in the air supply path and/or the air discharge path at a position where the dew is dominantly accumulated, the drainage function and the function of measuring the static pressure may be realized simultaneously, reducing the cost and ensuring air tightness.

Ventilating device

Supply air conduit () along which air is sent from outdoors to indoors by the air supply fan (), exhaust air conduit () along which air is sent from indoors to outdoors by the air exhaust fan (), and heat exchange element () provided at a position where supply air conduit () and exhaust air conduit () intersect, for exchanging heat between indoor air and outdoor air for ventilation are included. In addition, in exhaust air conduit (), humidity detection unit () is provided at a position upstream of heat exchange element (), and, in supply air conduit (), temperature detection unit () is provided at a position upstream of heat exchange element (). In addition, controller () reduces, when a temperature detected by temperature detection unit () and humidity detected by humidity detection unit () are predetermined values, speed of an air supply motor and an air exhaust motor so that air flow rates at which moisture neither condenses nor freezes are attained.
