3.1.3. Cooling Equipment

AC and EC produce cooling to meet the demand of the user. Their mathematical expressions are shown as follows:

$$\mathbb{C}\_{\text{ac}} = \mathbb{H}\_{\text{ac}} \cdot \eta\_{\text{ac}} \tag{8}$$

$$C\_{\rm cc} = P\_{\rm cc} \cdot COP\_{\rm cc} \tag{9}$$

where *Cac* and *Cec* denote the cold generated by AC and EC, *Hac* denotes the heat consumption of AC, *ηac* denotes the cooling efficiency of AC, *Pec* denotes the power consumption of EC, and *COPec* denotes the cooling coefficient of EC.
