A commercial air conditioner has a cooling capacity of $4.5\text{ tons of refrigeration}$. If $1\text{ ton of refrigeration}$ is defined as the heat transfer rate required to melt $1\text{ short ton } (2000\text{ lbs})$ of pure ice at $0^\circ\text{C}$ in $24\text{ hours}$, calculate this cooling capacity in kilowatts ($\text{kW}$). (Given: Latent heat of fusion for ice $= 334\text{ kJ/kg}$, $1\text{ lb} \approx 0.4536\text{ kg}$).
