CHC Tasks The most fundamental dilemma for space heating is that the need/load is highest when the resource/irradiance is lowest. Collectors for combined water heating, space heating, and space cooling will likely be integrated into the roof, which implies high angles of beam incidence, which is a further challenge. In energy-efficient new construction, one can assume that good envelope design minimizes or eliminates the space-heating load on sunny days. This implies that a relatively larger storage volume is needed compared to solar DHW, because the load occurs mostly on cloudy days when only stored energy is available. Space cooling can be done with unglazed collectors rejecting heat at night, or with glazed systems collecting heat to drive thermally driven chillers. The former has potential only in regions that are dry and comparatively mild. The latter has historically been difficult to make cost-effective because the extra equipment (i.e., absorption or desiccant subsystem) is not mass-produced competitively, is expensive, and thermal efficiency is low at temperatures compatible with flat-plate collectors (below ~80°C). Collector Tier-1 TIO • To supply the same amount of space heating saving as SWH savings, the glazing devoted to space heating must be larger (i.e., lower incidence, lower ambient temperatures and efficiencies). For an unglazed system, collector areas are roughly twice that required for a glazed system for equivalent savings. These larger-area systems must be fully integrated with the roof design. Storage Tier-1 TIO • Storage is usually envisioned as water, but schemes employing the ground beneath the building have appeal, especially for cooling where the ground temperature is a cooling resource. Compared to SWH, space heating requires larger ratios of storage volume per unit collector area, because energy must be stored for a longer time. The optimal storage size range must be established. Balance-of-System Tier-1 TIO • System control is more complex with CHC systems. Flow rates and interaction with efficiencies and stratification must be established. Depending on tank configuration, diverter strategies must be optimized. Research will focus on the collection, control, and distribution subsystems, excluding the thermal conversion machinery. Alternative control algorithms will be tested and optimized by simulation, followed by prototyping and testing. Commercially available absorption and desiccant systems are generally designed to run off natural gas supply, at temperatures higher than practical for flat-plate solar systems. However, absorption chillers designed to operate at temperatures more suitable for low-cost solar-thermal systems are now being developed in Europe and China. Liquid desiccant systems may become available that work well under 80°C. System Integration Tier-1 TIO • The modeling capability of system thermal performance is adequate, but models for these systems have yet to be defined, assembled, and verified. Once the performance of various system designs in various climates has been quantified, cost goals can be refined. At this stage, a decision to proceed with an industry request for proposal is made, possibly restricting the eligible system types. As the teams finalize conceptual design and provide cost estimates, potential cost/benefit can be defined for the various options and the most promising designs will be down-selected for engineering development. 95PDF Image | Concentrating Solar Power
