Embodiment approach 1

[0028] figure 1 It is a figure which shows the structure of the heat exchange ventilator which concerns on Embodiment 1 of this invention. The heat exchange ventilation device 21 has: an air supply duct 3, which is used to guide the outside air to the room; an exhaust duct 2, which is used to guide the indoor air The air is guided to the outside; the air supply blower 5 is arranged on the air supply duct 3 and generates air supply from outside to the room; the exhaust blower 4 is arranged on the exhaust air Road 2, and generate exhaust flow from indoor to outdoor; heat exchanger 1, said heat exchanger 1 is arranged in the middle of air supply air duct 3 and exhaust air duct 2, and passes through air supply air duct 3 heat exchange between the supply air flow and the exhaust flow passing through the exhaust air duct 2 ; and the control device 12 , which controls the operation of the supply air blower 5 and the exhaust blower 4 . A remote controller 18 for operating the heat e...

Embodiment approach 2

[0051] Figure 4 It is a figure which shows the structure of the heat exchange ventilator of Embodiment 2 of this invention. The heat exchange ventilator 26 of Embodiment 2 is not provided with the heater connection terminal 13, and instead of the externally connected heater 8, the built-in heater 27 is provided in the air supply duct 3, which is different from that of figure 1 The heat exchange ventilator 21 of Embodiment 1 shown is different. The built-in heater 27 is a heater that heats the supply air flowing into the heat exchanger 1 through the supply air duct 3 .

[0052] In the heat exchange ventilator 26 according to Embodiment 2, information indicating whether or not to use the heater is stored in the first setting storage unit instead of information indicating whether or not the heater is connected. The action of heat exchange ventilator 26 and image 3 The operation of the heat exchange ventilator 21 according to Embodiment 1 shown is the same.

Abstract

A heat exchanger ventilation device comprising: a heater connection terminal that is connected to an externally connected heater (8), wherein the heater is disposed in an outside air supply duct connected to the outside of an air supply passage and heats the air supply flow that is flowing into a heat exchanger by passing through the air supply passage; a temperature sensor (6) that measures the temperature of the air supply flow passing through the air supply passage; and a control unit (22) that controls operating of an air supply blower (5) and an exhaust blower (4) as well as turning the externally connected heater (8) on and off on the basis of the measurement results of the temperature sensor (6). The air supply blower (5) can operate at a plurality of intensities for which the generated air supply flow rates are different. The control unit (22) prevents a state in which the air supply blower (5) operates at an intensity that is lower than a preset intensity while the externally connected heater (8) is on.

Description

technical field [0001] The present invention relates to a heat exchange ventilator having a heater for heating outside air introduced into a heat exchanger from the outside. Background technique [0002] In a cold region, when the outside air is introduced into the room without change, there may be a problem that condensation is generated or a cold airflow that gives a feeling of cool wind is generated. Therefore, when the temperature of the outside air is lower than the heater ON threshold temperature, the outside air may be supplied into the room after being heated by the heater. [0003] If it is a product with a built-in heater that can adjust temperature by control or a PTC (positive temperature coefficient: positive temperature coefficient) heater, it can continue heating and ventilation by heater. For the heater, in order to simplify the control and to suppress the cost and size, a method of controlling the heater only by turning on and off the power to the heater is...
