Problem 2.92

A window-mounted room air conditioner removes energy by heat transfer from a room and rejects energy by heat transfer to the outside air. For steady-state operation, the air conditioner cycle requires a power input of 0.434 kW and has a coefficient of performance of 6.22. Determine the rate that energy is removed from the room air, in kW. If electricity is valued at $0.1/kW ? h, determine the cost of operation for 24 hours of operation.

Step-by-Step Solution:
Step 1 of 3

 Material properties: characteristics that distinguish and identify a material o Each material has properties that differentiate it from every other material  These properties originate at the atomic/molecular levels MATERIAL PROPERTIES:  Chemical: characteristics of a substance associated with its formulation and reactivity with other substances and environment o Composition: (which elements) The periodic table o Atomic arrangement: How are the atom arranged  Mechanical: characteristics of a substance related to its ability to withstand applied forces and durability o Strength o Hardness o Ductility/malleability o Toughness o Modulus of el
