Title:
HEATED AIR GENERATING APPARATUS
Document Type and Number:
Japanese Patent JP2018128224
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heated air generating apparatus which can cope with a change of concentration in exhaust gas with energy conservation.SOLUTION: A heated air generating apparatus according to the present invention has: an air supply pipe through which ambient air is introduced; an air supply valve provided in the air supply pipe; a heater provided in the air supply pipe; an exhaust pipe arranged so as to be connected to a device which is a supply object; an exhaust concentration sensor for detecting concentration of exhaust gas in the exhaust pipe; an exhaust valve provided in the exhaust pipe; a by-pass pipe for bypassing the exhaust pipe and the air supply pipe; a concentration adjuster for adjusting an opening of the air supply valve and an opening of the exhaust valve on the basis of the exhaust gas concentration detected by the exhaust concentration sensor; and an exhaust heat recovery device connected to the air supply pipe and the exhaust pipe for heating introduced ambient air. The exhaust heat recovery device is a heat pump using a coolant as an operating fluid.SELECTED DRAWING: Figure 1
