This thesis is about the meaning of ‘The enemy’ as an object. I will make use of the phenomenology in study about what the way of poet’s understanding and recognition as an subject. Phenomenological approach is the most reasonable to simplify that explanation, because this thesis is undering both epistemological view of poet as an subject and ontological view of ‘The enemy’ as an object. And, the follow sentences are why this thesis is on the side of the epistemology than the ontology. For sementic works of poet are not obscurity, the enemy on the poetry is not also apper as a concreat object with identity. But, the enemy as bieng an object preys on the poet’s mind without a pause. The enemy is out of existence but it is still in existence. With that the enemy is in connection with the poet’s consciousness. The enemy on the condition of none examination makes the meaning clearer with a take it’s place in the conscious as an object. If the enemy is presented as the concrete object, it can be exist only as the object for fight. But, it is difficult to make with the ontology of the enemy, because the meaning of the enemy is under construction and the poet is in the very confusion. And what is made through a study on the enemy as an object is not a universal truth about the enemy. Therefore, we can make it through the study on the relation between the poet and the enemy as an opposite.

In the present study, the performance characteristics of the heat pump chiller under heating conditions were experimentally investigated. Capacity, input power and COP under overload, frost and defrost conditions were obtained. The experimental data for the heat pump chiller were measured using the air-enthalpy calorimeter and the constant temperature water bath. At overload condition, the heating capacity and COP increase about 25.7% and 19.1%, respectively. The variations of the evaporator, the compressor outlet and the condenser temperature were obtained under frost and defrost conditions. The frost and defrost period of the heat exchanger decreases about 36.0~56.1%.
