2. Description of the Related Art In recent years, in order to improve comfort and energy saving of a house, the heat insulation and airtightness of the house have been advanced. On the other hand, however, the harmful effects of the increased airtightness have been highlighted. The following two points can be mentioned as the main ones of the adverse effects.

(1) Since the natural ventilation volume decreases, the air quality in the room deteriorates (air quality is the quality of air and indicates the cleanliness of air. For example, monoxide contained in air. If the proportion of pollutants such as carbon, carbon dioxide, dust, pets, and odors of cigarettes is high, the air quality is poor, and if the proportion is low, the air quality is good.

(2) Since the amount of natural ventilation decreases, the humidity in the room rises due to breathing from the human body, perspiration, cooking, laundry, etc. As a result, water vapor condenses on the walls and windows facing the outside, causing mold and tick damage.

The most convenient way to solve the above-mentioned problems is to provide a ventilation fan and operate it. However, the heating load increases in the winter when the temperature difference between the indoor and outdoor is large, and the indoor temperature distribution is uneven. However, the effect of high heat insulation and high airtightness is halved, so it is not a desirable method.

Therefore, conventionally, in addition to the heating and cooling equipment such as a heat pump air conditioner and a gas fan heater, a ventilation fan capable of heat exchange ventilation with high energy saving is provided for ventilation, and the above problems (1) and (2) are solved. Was dealing with.

The heat exchange type ventilation fan exchanges heat between the indoor exhaust air and the outdoor air supply and the outdoor air supply to the indoor air by using a heat exchanger to reduce the cooling and heating load by ventilation. The heat exchange type ventilation fan has been generally put into practical use for about 20 years, and a typical example of its structure is shown below.
