Adaptation of Subcool Condenser for An Air Conditioning System Employing An Internal Heat Exchanger.

Recently, the use of air conditioning systems is growing rapidly due to increasing global temperatures. Considering enormous growth in the application of the air conditioning system, there is an urgent need to improve design, performance, and efficiency thereof. For example, the air conditioning systems that are being used these days are required to provide improved efficiency per unit of power consumed, and they are also required to have a smaller form factor as compared to conventional air conditioning systems. Therefore, a lot of modern air conditioning systems employ components such as internal heat exchangers, thermal expansion valves and forth to improve their performance while having a small form factor. In this study a condenser is adapted to be used for an air conditioning system employing an internal heat exchanger. Wherein the condenser subcool area is in a optimized range of a frontal condenser area; and a free flow area within the plurality of tubes of the subcool region of the at least one refrigerant flow section for the refrigerant flow within the plurality of tubes of the subcool area, wherein the free flow area is in a definite optimum range. The sizing of subcool portion of condenser inline of internal heat exchanger capacity for a given system results upto 10% improvement in the coefficient of performance of AC system.
