Chilled water storage, which utilizes the sensible heat (4.184 kJ kg −1 K −1) to store cooling, needs a relatively large storage tank as compared to other storage systems that have a larger latent heat of fusion. However, it has wide application because of its suitable cold storage temperature (4–6 °C).
9.3. Saving on the maintenance cost. The average cost of maintaining an air-cooled chiller unit in Saudi Arabia is about SR 100 per kW (cooling) per year, based on 20 years of useful chiller-life. A reduction of 1820 kW (cooling) in the chiller capacity will reduce the yearly maintenance cost by SR 182,000.

The energy flow density of soil is small, 20–40W/m 2, generally 25W/m 2. This determines that when the soil is only used as the low-level heat source of the heat pump, its load should not be too large. Generally, it is only used when the load is no more than 1 MW. In addition, ground source heat pump has certain area requirements.
