“…It is acknowledged that liquid-gas absorption technology was first introduced into the study of low-grade thermal energy transportation in the 1990s [13]. The LiBr-H 2 O working pair is commonly used for heat transportation and desiccant cooling, and the chemical solution could be transported at an ambient temperature [14]. Thus, the costs of pump, tube and other auxiliary equipment are able to be reduced when compared with other energy-transportation technologies at a low temperature [7].…”

Thermal-driven refrigeration technologies, e.g., absorption- or adsorption-type, are gathering momentum since they can utilize low-grade heat from industrial, solar or geothermal energy. However, heat sources and end users are usually mismatched, which could lead to potential heat pollution and increased carbon emissions. Long-distance thermal energy transportation is good for district heating and cooling, which is of great significance if it can achieve a high energy-transportation density and low heat loss. In this paper, a compression-assisted chemisorption chiller driven by a low-temperature heat source for cold transportation is initially proposed, which aims to transport liquid ammonia with chemical potential and generate a cooling effect for end users. A feasibility analysis of the compression-assisted chemisorption chiller is preliminarily performed for 2 km cold transportation. The results show that the highest theoretical coefficient of performance and the energy efficiency of the compression-assisted adsorption chiller using a sodium bromide–ammonia working pair can reach 0.46 and 0.25, respectively, when the evaporation temperature is 20 °C. Among the three selected low-temperature salts, ammonium chloride–ammonia shows the best performance, which is up to about 40% higher than those of sodium bromide–ammonia and barium chloride–ammonia. It is demonstrated that compared with common absorption chillers, a compression-assisted adsorption system has a reasonable working efficiency to transport cold energy when the low- or ultralow-temperature heat source, e.g., lower than 60 °C, is required to be utilized.

Renewable energy use in agricultural applications is essential for sustainable production. Resorption cooling systems can be operated for agricultural cooling applications by using thermal energy derived from geothermal springs with sufficient temperature. Since the resorption cycle uses ammonia-water solution, cold storage and industrial cooling processes below 0°C can be actualized efficiently. In this article, a geothermal powered resorption system for cold storage of apple fruit is investigated. Technical features and cooling performance of the resorption system are analysed and compared to the other conventional cooling systems. Results showed that, geothermal powered resorption cooling systems can annually cover the cooling load of the cold storage application with adequate cooling temperature and capacity. Moreover, the use of the geothermal powered resorption system enables to set up safer and more economic cooling applications with the similar cooling performance compared with the alternative sorption cooling systems, and provides substantial economic benefits by reducing the cooling costs in agricultural production with lower operational costs.
