Final answer:
An air conditioning system with a sensible heat load of 14 kW and a latent heat load of 9 kW can be considered as a heat pump. The coefficient of performance (COP) is a measure of its efficiency. To determine the cold reservoir temperature, we can use the formula: COP = Qh / W, where COP is the coefficient of performance, Qh is the amount of heat transferred to the hot reservoir, and W is the work input.
Step-by-step explanation:
An air conditioning system with a sensible heat load of 14 kW and a latent heat load of 9 kW can be considered as a heat pump. A heat pump is a device that can transfer heat from a cold reservoir to a hot reservoir. The coefficient of performance (COP) is a measure of its efficiency.
To determine the cold reservoir temperature, we can use the formula: COP = Qh / W, where COP is the coefficient of performance, Qh is the amount of heat transferred to the hot reservoir, and W is the work input. In this case, the COP is given as 12.0, so we can set up the equation: 12.0 = Qh / (14 kW + 9 kW). Solving for Qh gives us 324 kW. Since the system is supplying heat, the heat transfer is from the cold reservoir to the hot reservoir. Therefore, the cold reservoir temperature is higher than the hot reservoir temperature.
