As refrigerant vapor flows through the tubes, it condenses to liquid and releases heat that the air stream carries away. The condenser is on the high side.
An air condensor takes in the surrounding air(at about 45-50 degree celcius). The vapour at high pressure enters the condensor and accepts the latent heat of condensation from the hot air thereby...
