Abstract
In THIC systems, the required temperature of the high-temperature cooling source during summer is significantly higher than that of conventional systems. As there is no dehumidification requirement, the chilled water temperature could be increased from 5 to 7 °C in conventional systems to 16–18 °C in THIC systems. This offers the opportunity to utilize natural cooling sources, e.g., deep phreatic water, ground-source heat exchangers, and direct or indirect evaporative cooling methods in dry regions.l If no natural cooling sources are available, a vapor compression system can be applied instead. Due to the higher evaporating temperature of the vapor compression cycle, the operating compression ratio of chillers in THIC systems is significantly different from that in conventional systems. Therefore, new requirements are proposed in terms of the chiller design and device development of the vapor compression cycle for THIC systems. In this chapter, typical high-temperature cooling sources are introduced.
