Kontrollanordning för värmelagrande ventilationsaggregat

摘要

A control device is disclosed which suitably controls the operation of first and second fans in a heat collection type ventilation equipment. The heat collection type ventilation equipment comprises an air supply passage for introducing the outside air into the inside, a first fan disposed in the air supply passage, an air discharge passage for discharging the inside air to the outside and a second fan disposed in the air discharge passage. A heat exchanger exchanges heat between the outside air passing through the air supply passage and the inside air passing through the air discharge passage. A first sensor detects the temperature of the outside air and a second sensor detects the temperature of the inside air. The control device compares the sum of the temperatures of the outside and inside air detected by the first and second sensors with a reference temperature and operates the first fan at an operating ratio below 100% whenever the sum of the temperatures of the outside and inside air is below the reference temperature.
