Title:
HEAT EXCHANGE VENTILATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/003365
Kind Code:
A1
Abstract:
This heat-exchange ventilation device (1) has: an air-supply blower device (11) for generating an air supply flow; an air-discharge blower device (10) for generating an air discharge flow; a heat exchanger (19) for performing heat exchange between the air supply flow and the air discharge flow; an external air temperature sensor (3) for measuring the temperature of the air supply flow; and a control unit (14) comprising a heat-generation-amount-setting unit that sets a heat generation amount of a preheater (18) for heating the air supply flow before the same passes through the heat exchanger (19), the heat generation amount being set on the basis of to which of a plurality of preset temperature ranges the temperature difference between a set temperature and a measurement result from the external air temperature sensor (3) belongs.
