Description

Split system air conditioners are used to cool, dehumidify and also heat rooms. The consist of an inner and outer unit.
In the inner unit there is a heat exchanger with fan working as an evaporator in the refrigeration circuit during cooling operation. During heating operation it works as a condenser. The outer unit contains a compressor, another heat exchanger, expansion element (e.g. capillary tube) and an element enabling the change-over from cooling to heating operation. In cooling operation the evaporating refrigerant in the heat exchanger of the inner unit withdraws heat from the room air. In the outer unit the heat in the heat exchanger is discharged to the ambient air by condensing the refrigerant. During heating operation the heat transport is reversed.

Learning Objectives/Experiments
