Integral type air conditioning apparatus

An integral type air conditioning apparatus comprising:

• a base frame;
• an outdoor air circulation unit mounted on said base frame and including an outdoor heat exchanger, and an outdoor air circulation circuit operably coupled to said outdoor heat exchanger to allow outdoor air to flow by said outdoor heat exchanger;
• an indoor air circulation unit mounted on said base frame and including an indoor heat exchanger, and an indoor air circulation circuit operably coupled to said indoor heat exchanger to allow indoor air to flow by said indoor heat exchanger, said indoor air circulation circuit including an indoor air guide with a ventilation opening formed therein;
• a compressor mounted to said base frame;
• a refrigerant-circulating pipe operably connected to said compressor and to each of said indoor heat exchanger and said outdoor heat exchanger;
• a ventilation device pivotally mounted to said indoor air circulation unit for pivotal movement between a first position in which it covers said ventilation opening formed in said indoor air guide and a second position spaced from said first position;
• and
• wherein said ventilation device includes an elongated ventilation operation lever having first and second opposing ends and being pivotally mounted to said indoor air circulation unit at a pivot point located intermediate said first and second ends of said ventilation operation lever, and a ventilation door integrally fixed to said first end of said ventilation operation lever such that said ventilation operation lever and said ventilation door constitute a unitary member in which said ventilation door is non-movably mounted relative to said ventilation operation lever.
