“…In Figure 9, it is demonstrated that the internal cooling power in the evaporator is strongly influenced by the quantity of the solution in the absorption cooling system. As stated earlier, the minimum volume is the critical volume determined by the known volume of the components used in the system; this volume can be calculated from Equations (13) to (16). The critical volume was the solution volume used for performing the tests presented previously.…”

Summary The present study reports the experimental results of a new absorption cooling system utilizing stainless steel plate heat exchangers in all the main components. The system operated with the ammonia‐lithium nitrate working pair. Several parametric analyses were performed in order to investigate the effect of the generation and condensation temperatures, solution mass flow rate, solution volume and expansion valve aperture on the cooling power, evaporation temperatures, and coefficient of performance (COP). Generation temperatures varied from 80°C to 95°C, while condensation temperatures varied between 20°C and 32°C. The system achieved a cooling power of 3.1 kW, cooling temperatures as low as 6°C, and internal coefficients of performance of approximately 0.62. The cooling power increased 20.3% with an increment of the solution mass flow rate from 1 kg/min to 4 kg/min. From the expansion valve analysis, it was found the cooling power varied from 0.28 to 2.29 kW while the COP varied from 0.032 to 0.23 for the corresponding test conditions.

Summary The modeled operating characteristics of a single‐effect ammonia/lithium nitrate absorption heat pump‐transformer (type III absorption heat pump) are presented and compared to other working pair options and absorption heat pump cycles. Heat and mass balance equations are given. The effect of cycle operating parameters is shown on cycle thermal efficiency and solution pump power. It is shown that the ammonia/lithium nitrate working pair would achieve a performance a little less efficient than a water/lithium bromide system. Ratios of useful heat delivered to driving heat of nearly 2 are shown, with this system, to be achievable over a wide range of operating conditions. Ammonia/lithium nitrate has practical advantages over water lithium bromide in relation to corrosion, construction materials, and operating pressures. Both working mixtures have high viscosities in the absorbent/refrigerant solutions. However, an ammonia/lithium nitrate system has much higher available pressure drops for the economizer allowing the designer greater leeway in the use of enhanced heat exchange techniques. Costs and payback are commented upon.
