An absorption heating and cooling system having an absorber, which allows the gaseous refrigerant to be absorbed by the absorbent, condensed by its heat, and thus the liquefaction of the gaseous refrigerant while the heating operation takes place, and an evaporator that allows the liquid refrigerant to evaporate by heating and thus cooling process to be carried out, wherein a separation unit using a method of separation by solidification employed which works through the icing/crystallization/freezing methods and which enables the separation the refrigerant-absorbent mixture.

A solar collection system is provided in which an absorption refrigeration system is included to generate water from atmospheric moisture, and to do so without the use of an electrically operated compressor. At least a portion of the solar energy captured by the solar collection system is used to operate the absorption refrigeration cycle. The absorption refrigeration cycle provides cooling that causes water in the atmosphere to condense into a liquid that can be collected and used for various applications. As one example, the collected liquid can be used for the cleaning of the solar collection system of contaminants like dust or bird drippings. In other applications, the water can be used outside the solar collection system including, but not limited to, irrigation, drinking, and other industrial purposes.

An absorption refrigerator using a circulation cycle of a regenerator, a condenser, an evaporator, and an absorber includes temperature sensors, a storage unit storing the approximation function for obtaining the second concentration based on second detection results obtained by each of the temperature sensors, a calculation unit to apply the second detection results to the approximation function to obtain the second concentration and a control unit to execute control in accordance with the second concentration. The approximation function is obtained using a response surface method by interpolation or approximation, based on data including first detection results obtained by temperature sensors and first concentrations each corresponding to when each of the first detection results has been obtained.

Liquefaction of industrial gases or gas mixtures (hydrocarbon and/or non-hydrocarbon) uses a modified aqua-ammonia absorption refrigeration system (ARP) to chill the gas or gas mixture during the liquefaction process. The gas is compressed to above its critical point, and the heat of compression energy may be recovered to provide some or all of the thermal energy required to drive the ARP. A Joule Thomson (JT) adiabatic expansion process results in no requirement for specialty cryogenic rotating equipment. The aqua-ammonia absorption refrigeration system includes a vapour absorber tower (VAT) that permits the recovery of some or all of the heat of solution and heat of condensation energy in the system when anhydrous ammonia vapour is absorbed into a subcooled lean aqua-ammonia solution. The modified ARP with VAT may operate at pressures as low as 10 kPa, and the ammonia gas chiller may operate at temperatures as low as −71° C.
