Abstract
A vehicle air conditioning apparatus is provided. The vehicle air conditioning apparatus includes: a plurality of seat air conditioning units configured to selectively perform cooling or heating for corresponding seats installed in a cabin, respectively; and a plurality of exhaust ducts for discharging, outside the cabin, part of air used in the plurality of seat air conditioning units. At least part of the plurality of exhaust ducts is merged.
Claims4
A vehicle air conditioning apparatus comprising:
- a plurality of seat air conditioning units configured to selectively perform cooling or heating for corresponding seats installed in a cabin, respectively;
- and
- a plurality of exhaust ducts for discharging, outside the cabin, part of air used in the plurality of seat air conditioning units,
- wherein at least part of the plurality of exhaust ducts is merged,
- each seat air conditioning unit comprises:
- a condenser passage housing a condenser for condensing a refrigerant;
- an evaporator passage housing an evaporator for evaporating the condensed refrigerant;
- an outside air passage unit inducing outside air, and being connected to an outside air inlet of the condenser passage and an outside air inlet of the evaporator passage;
- an inside air passage unit inducing inside air and being connected to an inside air inlet of the condenser passage and an inside air inlet of the evaporator passage;
- and
- a passage switching device including a first door opening any one of the outside air inlet of the condenser passage or the inside air inlet of the condenser passage and closing the other, and a second door opening any one of the outside air inlet of the evaporator passage or the inside air inlet of the evaporator passage and closing the other,
- the passage switching device performs switching with the first and second doors such that during cooling operation, the outside air is guided in a direction toward the condenser and during heating operation, the outside air is guided to a direction toward the evaporator,
- the outside air passage unit comprises:
- a first outside air passage through which the outside air flows into the condenser;
- and
- a second outside air passage through which the outside air flows into the evaporator,
- the inside air passage unit comprises:
- a first inside air passage through which the inside air flows into the condenser;
- and
- a second inside air passage through which the inside air flows into the evaporator,
- an air inlet of the first outside air passage and an air inlet of the second outside air passage are merged,
- an air outlet of the first outside air passage and an air outlet of the second outside air passage are merged, and
- an air inlet of the first inside air passage and an air inlet of the second inside air passage are merged.
