Proportion of liquid cooling in commercial buildings

Can liquid desiccant cooling system be used in commercial buildings?

Therefore, in our research, the liquid desiccant cooling system with packed dehumidifier and regenerator is adopted as the AC system in commercial buildings for the energy performance simulation. Also, energy consumptions of the conventional system in these buildings were calculated for comparison.

How LDCs is used to simulate energy consumption of commercial buildings?

LDCS, which is consisted of the cooling coil and liquid desiccant ventilation system, was adopted in this research to simulate the energy consumption of commercial buildings. Fig. 1 shows the schematic of the whole system. The cooling coil was driven by vapor compressors.

How much water does a commercial building use?

Using water consumption data from the Commercial Buildings Energy Consumption Survey (CBECS), EIA estimates that the 46,000 large commercial buildings (greater than 200,000 square feet) used about 359 billion gallons of water (980 million gallons per day) in 2012.

Why are liquid air cooling systems better than evaporative cooling towers?

Furthermore, the high energy storage density of liquid air determines that liquid air-based cooling systems have a greater footprint density compared to evaporative cooling towers. Additionally, liquid air cooling systems do not involve evaporative losses of cooling water, reducing the reliance of data center construction on water sources.

How much power does a liquid air cooling system use?

For an optimized liquid air-based cooling system with an average IT power of 6.97MWh, power consumptions of liquid-air pump and immersion-coolant pump are 0.03 MWh and 0.01 MWh, respectively. According to Eq. (26), the pPUE can be determined as 1.006.

Can space-conditioning loads be simulated in commercial buildings?

This report describes the development of a database of space-conditioning loads for commercial buildings, based on prototypes developed for the EnergyPlus simulation software, with a particular focus on cooling loads. The prototypes cover sixteen building types and three vintages, which were simulated in eighteen climate zones.
