The invention relates to an ventilating and air conditioning apparatus including a circulating fan for sucking air from a sucking port open to a first indoor space and blowing the air through a blowout port into the first indoor space, a ventilating fan for sucking air from an exhausting port open to a second indoor space and evacuating the air to the outdoors for ventilation, and a refrigerant circuit wherein pipes are connected to circulate a refrigerant to a compressor for compressing the refrigerant, a first heat exchanger for exchanging heat between the air in the first indoor space to which the air is blown from the circulating fan and the refrigerant, an expanding mechanism for expanding the refrigerant, and a second heat exchanger which exchanges heat between the air in the second indoor space to which the air is blown from the ventilating fan and the refrigerant, in this order.
