“…Since battery storage is still very expensive, cooling production by PV is limited to sunshine hours only. However, storage of cooling produced during the sunshine hours for later use is a viable option (Zeyghami et al [20]). They reported that in solar thermally driven cooling systems, the heat from a solar collector can be used to produce mechanical power to compress the refrigerant vapor in a conventional VCC or as a heat source for the generator of a sorption cooling cycle.…”

“…However, these cooling systems have some drawbacks that can be addressed by thermo-mechanical cooling systems (Zeyghami et al [20]). In a thermo-mechanical cooling system, the heat gained from a solar collector is converted into mechanical work, which is used to compress the working fluid in a VCC directly (i.e.…”

“…ejector cooling cycle) or indirectly (i.e. coupled with an Organic Rankine Cycle).The most common thermo-mechanical solar cooling systems are the solar Rankine cooling and solar ejector cooling systems (Zeyghami et al [20]). As per Zeyghami et al [20], solar thermo-mechanical cooling systems recently have received a renewed attention due to merits like: using appropriate working fluids to produce low refrigeration temperatures (less than 0°C); producing electricity when cooling is not needed by coupling the prime mover with an electric generator; maintaining high performance at off-design conditions and utilization of a wide range of temperatures from solar collectors.…”

“…The amount of cooling achieved by a refrigerator per unit of heat supplied is usually given by the COP. The COP value of an intermittent adsorption refrigerator varies from 0.15 to 0.35 with heat source temperature at 60-165 °C [10]. The COP value of an adsorption refrigerator driven by a solar collector can be obtained using the following Eq.…”

Abstract. In the present work, the performance of an adsorption refrigerator driven by a solar collector was investigated. The adsorbent used in this study was 6.5 kg ordinary granular activated carbon of coconut shell produced in the Sumatera Utara province of Indonesia, 3 liters of methanol as adsorbate and 4.5 litres of water as the medium that was cooled. The experiments were carried out under varying weather conditions during seven cycles with total solar radiation about 2.681-3.918 kWh/m 2 /cycle. In this study, the values of the coefficient of performance (COP) obtained were about 0.0827-0.1271. The values of specific cooling power (SCP) obtained were in the range of 0.01839-0.01883 kW/kg. The experimental results show that the adsorption refrigerator system can deliver an evaporator temperature of about 2.81-13.61°C.

Modern diesel building is developing in the direction of emissions with exhaust gases reduction and improvement of unit power, fuel efficiency, and engine lifetime. The achievement of high ecological, technical and economic indexes in diesel-fueled vehicles demands power efficient control and improvement of devices, which realized gas exchange processes. Exhaust gases energy is used in the gas exchange system of diesel-fueled vehicles. It is necessary for the improvement of diesel-fueled vehicles gas exchange efficiency to combine in one device the control of all of the following procedures: exhaust gases recirculation into the cylinder under small and no-load conditions for nitrogen oxide emission reduction; exhaust gases bypassing under turbocharger control on variable load operation for carbonic oxide, soot, and particulate matter emission reduction; exhaust gases use for air ejection in the process of circulation through charge air cooler under cooling conditions before air injection into the cylinder.
