Abstract:
1. A ventilating and air conditioning apparatus comprising: a circulating fan for sucking air through a sucking port open to a first indoor space and blowing air through a blowout port open to the first indoor space; a ventilating fan configured to suck air through an exhausting port open to a second indoor space and the sucking port open to the first indoor space and evacuate the air to outdoors for carrying out ventilation; a refrigerant circuit including: a compressor for compressing a refrigerant; a first heat exchanger for exchanging heat of the air blown into the first indoor space by the circulation fan with the refrigerant; an expanding mechanism for expanding the refrigerant; and a second heat exchanger for exchanging heat of air sucked from the second indoor space by the ventilating fan with the refrigerant, wherein the compressor, the first heat exchanger, the expanding mechanism, and the second heat exchanger are coupled to each other with pipes for the refrigerant to circulate therethrough in this order, the ventilating and air conditioning apparatus further comprising a flow-path switching valve for switching a circulating direction of the refrigerant firstly to the compressor, secondly to the second heat exchanger, then to the expanding mechanism, and then to the first heat exchanger in this order, wherein the refrigerant in the second heat exchanger radiates heat to air to be evacuated to the outdoors by the ventilating fan, and the refrigerant in the first heat exchanger absorbs heat from air to be circulated in the first indoor space by the circulating fan for cooling the first indoor space.
