Abstract:
1. A heat exchanger unit comprising: a supply air channel flowing from an outdoor space to an indoor space; an exhaust air channel flowing from the indoor space to the outdoor space exchanging heat with the supply air channel; a first blowing portion including a double-suction first impeller that produces an airflow and a first casing that houses the double-suction first impeller, the double-suction first impeller including a first suction inlet, a second suction inlet and a first impeller side-partition member that divides an interior of the first impeller into a first space at a first suction inlet side of the double-suction first impeller and a second space at a second suction inlet side of the double-suction first impeller, and the first casing including a first casing side-partition member extending from an inner circumference of the first casing to a vicinity of an outer circumference of the first impeller side-partition member; a first air channel connecting the indoor space to the first suction inlet side of the double-suction first impeller; a second air channel guiding air flow from the double-suction first impeller to the indoor space; and at least one air conditioning element disposed in at least one of the first air channel and the second air channel to condition air supplied to the indoor space, the at least one air conditioning element including at least one selected from a deodorization element that reduces odorous components in passing air, an air purification element that reduces harmful components in passing air and a humidification element that increases moisture in passing air, a part of one of the supply air channel and the exhaust air channel connecting the second suction inlet side of the double-suction first impeller to the indoor space.
