Airconditioner having selectively operated condenser bypass control

An air conditioner comprising:

• main heating means for heating air passing therethrough;
• compressor means for compressing a refrigerant and discharging said compressed refrigerant therefrom;
• condenser means for condensing the refrigerant discharged from the compressor and for discharging condensed refrigerant therefrom;
• a heat exchanger receiving the discharged condensed refrigerant;
• first pressure reducing means for reducing the pressure of refrigerant which flows into the heat exchanger;
• a main conduit which connects the compressor, the condenser, the heat exchanger and the pressure reducing means to each other;
• a bypass conduit having a first end connected to the main conduit downstream of the compressor and a second end connected to the main conduit upstream of the heat exchanger, the bypass conduit being for introducing the compressed refrigerant toward the heat exchanger while bypassing the condenser;
• valve means which selectively opens the bypass conduit and the main conduit between the compressor and the condenser;
• a check valve disposed in said main conduit between said condenser and said heat exchanger;
• and
• second pressure reducing means disposed in said bypass conduit between said valve means and said second end for reducing pressure of compressed refrigerant flowing through said bypass conduit;
• the heat exchanger being disposed in such a manner that the heat exchanger exchanges heat with air which is subsequently heated by the main heating means, thereby complimentarily working to augment total heat added to the air.
