Abstract:

The main purpose of our research is to increase the utilization of solar thermal energy to supply a refrigerator with vapor compression and reduce the refrigeration power needed for cooling. Combined Hybrid Solar - the vapor- compression refrigerating unit has been built and operates under Mutah University's environment in Jordan. The systems were made up of a capillary tube, condenser, evaporator, and collector. The vapor-pressure refrigerator was incorporated with the classic water-solar system to minimize the compressor's duty and to reduce power consumption in heating the amount of water held in the pipe to be sent along the tube outside the evaporator. After that, it will be returned to the compressor, But at a lesser temperature, to minimize compressor workload and enhance cooling performance. Before the compressor was developed, a solar collector system had been created to maximize its temperature before reaching the compressor to improve C.O.P, and the difference in temperature was remarkable. The vapor-compression refrigerator unit was powered by many generators: solar collector that has been discharged, photovoltaic system, flat plate solar collector. Two groups of tests have been performed experimentally on the partial solar compression refrigerator integrated into a hybrid system. First in the vapor compression refrigerator only, and the second in the Hybrid solar compression refrigerator incorporated. Total sunlight and different temperatures, current, and voltage were measured for many months each hour of the day. The performance coefficient was determined found 2.019, 2.432 respectively. Many auxiliary instruments are utilized to measure the temperature in irradiation networks, voltage, and night-time current every hour.

Abstract:

This experiment is to study an absorption refrigerator driven by solar cells. Hand-held or carried in vehicle can be powered by solar energy in places without power. In the evenings or rainy days, it is powered by storage battery, and it can be directly powered by alternating current (AC) power supply if available, and the storage battery can be charged full as a backup supply. The proposed system was tested by the alternation of solar irradiance 550 to 700 W/m2as solar energy and 500ml ambient temperature water as cooling load. After 160 minutes, the proposal refrigerator can maintain the temperature at 5–8°C, and the coefficient of performance (COP) of NH3-H2O absorption refrigeration system is about 0.25. Therefore, this system can be expected to be used in remote areas for refrigeration of food and beverages in outdoor activities in remote and desert areas or long-distance road transportation of food or low temperature refrigeration of vaccine to avoid the deterioration of the food or the vaccines.

Abstract:

This paper is focused on the performance of a solar-assisted DC refrigerator installed on the backside of the electric vehicle (EV). The experiments are performed by varying load conditions inside the refrigerator. The experimental setup consists of four solar PV panels, a charge controller, battery bank, voltage converter, DC refrigerator, and an electric vehicle. The temperature inside the refrigerator cabin was controlled with the thermostat position adjustment. The solar PV panels of the vehicle was generating 2.5-4 kWh energy on the average sunny day. The refrigerator's inside temperature was decreased with a faster rate at the third thermostat position and consuming higher energy at the seventh thermostat position among all load conditions. The fourth and fifth thermostat positions were better at maintaining the lower desired temperature inside the refrigerator cabin by consuming the minimum energy. The COP of the refrigerator was decreasing with the increasing compressor speed. The battery bank was able to run the refrigerator 240 hr, 96 hr, 72 hr for the no-load, 15 L load, and 25 L load conditions at the higher thermostat position. The vehicle was travelling 68.3 km, 65.3.6 km, 63.4 km distance in no-load, 100 kg, and 200 kg load conditions respectively by consuming 3010 Wh, 3230 Wh, and 3450 Wh energy. The travelling charge of this vehicle was 1-1.5 INR per kilometer.

Abstract:

This paper describes the thermodynamic optimization of a class of refrigerators without work input, which are driven by heat transfer from a solar collector. The model consists of a finite-size solar collector with heat loss to the ambient, and a refrigerator with three finite-size heat exchangers, namely, the evaporator between refrigeration load and refrigerant, the condenser between the refrigerant and the ambient, and the heat exchanger between the solar collector and the refrigerant. The total thermal conductance of the three heat exchangers is fixed. The solar collector heat loss to the ambient is proportional to the collector-ambient temperature difference. The first part of the paper reports the operating conditions for maximum refrigeration effect, specifically, the optimal collector temperature, and the optimal way of allocating the thermal conductance inventory to the three heat exchangers. For example, the optimal condenser conductance is equal to half of the total thermal conductance, and is independent of other operating parameters. The second part of the paper examines the changes in the optimal design when the price of the refrigeration load (pL) is different (higher) than the price of the heat input provided by the collector (pH). The optimal collector temperature and the optimal three-way allocation of the thermal conductance inventory are reported as functions of the price ratio pH/pL.

Abstract:

After the 2010 earthquake, Haiti committed to introducing 4 new antigens into its routine immunization schedule, which required improving its cold chain (ie, temperature-controlled supply chain) and increasing vaccine storage capacity by installing new refrigerators. We tested the feasibility of using remote temperature monitoring devices (RTMDs) in Haiti in a sample of vaccine refrigerators fueled by solar panels, propane gas, or electricity. We analyzed data from 16 RTMDs monitoring 24 refrigerators in 15 sites from March through August 2014. Although 5 of the 16 RTMDs exhibited intermittent data gaps, we identified typical temperature patterns consistent with refrigerator door opening and closing, propane depletion, thermostat insufficiency, and overstocking. Actual start-up, annual maintenance, and annual electricity costs for using RTMDs were $686, $179, and $9 per refrigerator, respectively. In Haiti, RTMD use was feasible. RTMDs could be prioritized for use with existing refrigerators with high volumes of vaccines and new refrigerators to certify their functionality before use. Vaccine vial monitors could provide additional useful information about cumulative heat exposure and possible vaccine denaturation.

Abstract:

The optimal performance of the solar-driven thermodynamics cycle system consisting of a solar collector and a four-temperature-level absorption refrigerator is investigated, based on the linear heat-loss model of a solar collector and the irreversible cycle model of a four-temperature-level absorption refrigerator. A fundamental optimum relation is derived, from which the optimum operating temperature of the solar collector, the maximum overall coefficient of performance and the corresponding coefficient of performance of the four-temperature-level refrigerator are determined. It is proven that the total thermal conductance of the heat exchangers must be divided optimally between the four heat exchangers. The effects of the cycle parameters on the optimum operating temperature of the solar collector and the performance of the system are discussed by detailed numerical examples. The results obtained can describe the optimal performance of solar-driven four-temperature-level refrigerator affected simultaneously by the internal and external irreversibilities.

Abstract:

The paper presents the performance and economic analysis of a simple photovoltaic powered vapor compression refrigeration system carried out on winter days in the eastern province of the Kingdom of Saudi Arabia. The system has a 66 W DC refrigerator, 100 W PV mono-crystalline module and a 100 Ah battery bank. The thermal loads were distributed in the refrigerator cabin using ice trays of 300 mL each for a total mass of 2.1 kg. The system performed continuously without any interruption or fault for the entire time of the experiment. The minimum time taking for complete formation of ice in the trays was 6 h and 40 min. A larger area to volume ratio, which enhances the heat transfer is created due to this load distribution pattern. A refrigeration efficiency of 60% was calculated after ice formation has been completed. At the maximum solar radiation level, the best PV efficiency and solar panel orientation efficiencies were 15.5% and 98%, respectively. It was however observed from the cost analysis that the system would not be economical without government subsidy on the system components or alleviating the current subsidy on the electricity cost in Saudi Arabia.

Abstract:

A new, completely passive, vapor compression refrigerator is described in this paper. This refrigerator combines elements of the heat pipe and the vapor jet refrigerator and is referred to here as a heat pipe refrigerator. It may be driven with heat from low temperature solar collectors or with industrial waste heat and used to provide cooling. Compression work is provided by gas dynamic processes and liquid pumping may be obtained using gravitational or capillary forces. No power is required for operation. The device has no moving parts and may be externally similar to a heat pipe with three heat transfer zones. The working fluid is chosen to match the desired operating temperature range. Water, at subatmospheric pressure, is an appropriate fluid for operation around room temperature. Theoretical considerations indicate that the thermal coefficient of performance of the heat pipe refrigerator will depend strongly on the magnitude of the temperature differences over which it is designed to operate. Results from a laboratory test confirm the concept and demonstrate cooling down to the freezing point using water vapor at 51°C to drive the device and with heat rejection at 18°C.

Abstract:

Absorption refrigerator is not a new concept. It provides advantages of being silent, of having no compressor, which also makes it lasting a long life cycle. Particularly, it can utilize low level waste energy. In this contribution, a 2-fluid aqua-ammonia prototype is analysed and an overall design and construction procedure of a mini-type, 3-fluid absorption refrigerator is given, with working fluids of organic compounds (R134a as refrigerant and Tetraethelene Glycol Dimethyl Ether as absorbent) and a pressure balancing gas. The aim of this project is to develop a potential mini-type cooling system for rural areas, where electricity is scarce or non-existed. The experiments showed the combination of R134a and TEG.DEM for mini-type solar absorption refrigeration is theoretically realisable; To have an ideal performance, except of interfusion of non-condensable gas and impermeability of the system, the filling methods, vacuum drawing state as well as the stability of input power are all crucial influence factors.

Abstract:

Refrigeration systems are necessary for people living in hot climates. A majority of tropical and subtropical countries uses electrical power as a source of cooling. During the seasons of high ambient temperature there is a significant cooling load due to increased level of energy consumption. Cooling systems are therefore necessary in African countries in order to keep medications and food in safe conditions. Furthermore, there is a power shortage crisis due to the high demand for cooling. TRNSYS software allows to simulate a complete solar-powered absorption cooling system. A model used in an experiment includes PV modules making it advantageous over a conventional cooling system. PV modules of assumed area are sufficient to maintain the temperature inside cooling device below 6°C over the whole year.

Abstract: The worldwide growth in call for refrigeration brought about the manufacturing of extra power and this, in turn, brought about extra use of CFCs. CFCs, in particular, are a notable factor in the ozone layer's depletion. TER (Thermoelectric Refrigerator) is a revolutionary option that eliminates the use of refrigerant. As a result, it is critical, especially in underdeveloped countries where extended life and inexpensive maintenance are required. The goal of this research is to design and build a functional TER that uses the Peltier effect to cool this volume to much lower temperature in under two hours and retain it for at least the next 1/2 hour. In this project, we created a TE system that works with both solar and electrical power. Food preservation, military or aerospace equipment, medicinal and pharmaceutical equipment are just some of the uses for the project.

Abstract:

The arrival of new technologies has increased the energy demand day by day and does not seem to slow down at any time soon. High energy demand is adding risk on energy depletion and cause of various environmental issues. Air conditioner, chiller, and refrigerator occupy a considerable amount of the world’s total energy usage and have also proved to be a massive contributor to various environmental impacts. This technology might sound like a luxury on the surface, but they are in high demand to achieve food security. They can also help lifesaving vaccines to reach even the isolated parts of the world. Even though solar thermal refrigeration is a popular field, this paper solely concentrates on PV integrated refrigeration. In this paper, a renewable integration technology where a solar photovoltaic system is used to supply the electrical energy required to drive an absorption cycle is studied and compared with the commercial AC absorption refrigeration system. The Coefficient of Performance (COP) of the AC and DC system was 0.18 and 0.14. The simple payback of the system is 10.2 years.

In today’s world, there is a strong need for an environment-friendly refrigerating system, therefore, our focus is on a solar powered vapour absorption refrigeration system. This project focuses on a cooling system that minimizes the dependency over electricity and to show our ability to save our resources for future generations. The objective of this work was to design and fabricate a vapour absorption refrigeration system, using LiBr-H20, as the refrigerants and powered by solar energy. Performance Evaluation of the system has been done on the basis of different operating conditions and parameters like, solar irradiance, collector, generator, condenser and evaporator temperature. The COP of the system was obtained as 0.1 and the capacity was 0.01 TR. Since it’s an ab-initio development it will be a unique one in terms of understanding and underlying engineering. The system is an eccentric one that can be operated by multiple heat sources like solar energy, biomass etc. without much change in the design.

Abstract:

Based on a traditional integrated solar combined cycle system, a novel integrated solar combined cycle (ISCC) system is proposed, which preferentially integrates the solar energy driven lithium bromide absorption refrigeration system that is used to cool the gas turbine inlet air in this paper. Both the Aspen Plus and EBSILON softwares are used to build the models of the overall system. Both the thermodynamic performance and economic performance of the new system are compared with those of the traditional ISCC system without the inlet air cooling process. The new system can regulate the proportions of solar energy integrated in the refrigerator and the heat recovery steam generator (HRSG) based on the daily meteorological data, and the benefits of the solar energy integrated with the absorption refrigeration are greater than with the HRSG. The results of both the typical day performance and annual performance of different systems show that the new system has higher daily and annual system thermal efficiencies (52.90% and 57.00%, respectively), higher daily and annual solar photoelectric efficiencies (31.10% and 22.31%, respectively), and higher daily and annual solar photoelectric exergy efficiencies (33.30% and 23.87%, respectively) than the traditional ISCC system. The solar energy levelized cost of electricity of the new ISCC system is 0.181 $/kW·h, which is 0.061 $/kW·h lower than that of the traditional ISCC system.

Abstract:

Solar power (photovoltaic) is one of the clean energies that is very well developed in a tropical country like Indonesia. This is due to the high intensity of the sun and shining throughout the year so that the annual energy obtained is relatively high. The solar energy system in this research was developed with a photovoltaic array system that can be optimized for angles and facing according to where the experiment was carried out. The solar system using Solar Control Charge (SCC) and an inverter in order to get both alternating and direct current output. This energy output from solar power is used to drive the medium temperature refrigerator system for storing fresh vegetables and fruit. The results obtained from this preliminary study are the best angle and direction is an angle of 15 degrees to the north. And this condition will be determined in the form of a fixed tilt on the solar power system located at the Bali State Polytechnic and its surroundings.

Abstract:

Objectives.The aim of the study is to develop a cyclic absorption refrigerator unit that implements technology for producing cold from solar radiation energy. Its distinctive feature comprises a highly developed solar receiving unit, consisting of two parallel-connected absorber generators whose reactors are installed in individual heat-insulated “hot box” cabinets.Method. The geometric characteristics of the absorber generator are based on the calculations of the optical and heat energy efficiency of the device models.Results. The physicochemical characteristics of activated carbons (AC) of various production are studied. The absorption capacity of the following working pairs is determined: AC-ammonia, AC-methylamine, AC-ethylamine. The calculated coefficients for the Dubinin-Radushkevich structural equations are obtained. An experimental solar energy refrigerator unit is tested using a working pair of AC-ammonia in an open test area. The operability of the upgraded device is proven. Exergetic coefficient dependencies are determined according to the developed software algorithm based on a simplified thermodynamic cycle. The areas of possible application and use of solar power refrigerator units with the studied working pairs are determined.Conclusion. The increased unit efficiency consists in the optimal layout of all elements of the absorber generator, including the reactor, two flat mirror concentrators, a thermal substrate, a reduced internal air space volume, a double-glazed window made of two sheets of glass and a calculated thickness of heat-insulating Ripor foamed polyurethane.

Abstract:

A combined cycle capable of heating and adsorption refrigeration is proposed, and the experimental prototype has been installed. The system consists of a heater, a water bath, an activated carbon-methanol adsorption bed and an ice box. This system has been tested with electric heating, and has been found that with 61 MJ heating, the 120 kg water in the bath can be heated from 22°C to 92°C, of while 9 kg ice at −1.5°C is made. The calculated COPsystem is 0.0591 and COPcycle is 0.41. After reconstruction to a real hybrid household water heater-refrigerator, when 55 MJ heating is added to 120 kg of 21°C water, and the condensing temperature is controlled at about 30°C, the result is the 4 kg water contained inside the methanol refrigerant evaporator was iced to −2°C, the cooling capacity of the ice and the refrigerant in the evaporator will maintain the 100 liter cold box for about three days below 5°C. The experiments show the potential of the application of the solar powered hybrid water heater and refrigerator. Theoretical simulation has been done, which is in good agreement with experimental results. This research shows that the hybrid solar water heating and ice-making is reasonable, and the combined cycle of heating and cooling is meaningful for real applications of adsorption systems.

Abstract:

On the basis of previous research work on solar solid adsorption refrigeration, some advanced application methods for a solar ice maker have been studied. These include the efficient design of a new adsorbent bed; experimental studies of working pairs for a solar ice maker using activated carbon—methanol and activated carbon—ethanol; the effects of sky cloud cover on a solar ice maker; and the efficient utilization of a solar ice maker with provision for heating and cooling. The provision of tables to assist in the choice of a mass-produced solar ice maker was also examined. Simulation of the characteristics of a solar ice maker has been undertaken in some areas in Tibet where the natural climatic conditions appear to be ideal for the operation of such a device.
