“…The anticipated variation of the daily refrigeration load of 200 metric ton (MT) capacity vegetable cold room for the assumed atmospheric condition and location (Kolkata, India), for the representative day (June 15) is shown in Fig. 3 [63,64]. Cooling load of the cold chamber increases during the day time for product loading and unloading, and for the change of environmental conditions.…”

In this work, a tri-generation system is proposed that relies on a biomass-gasification-based externally fired gas turbine (EFGT) generator and an array of solar flat-plate collectors. A LiBr-water-based absorption cooling (VAR) system utilizes the waste heat of a 100-kW power generator as well as solar thermal energy of a 200 sq. m. solar collector to run a vegetable cold store of 200 metric ton capacity. A domestic water-heating system is also integrated with the unit that recovers low-temperature thermal energy to produce 150 tons of hot water daily. The power generator shows its maximum electrical efficiency of 27.5% at 1100 °C turbine inlet temperature and 10 pressure ratio. The maximum efficiency of solar collector is found to be 48%. The overall energetic efficiency of the tri-generation system varies in the range of 59 to 76%, while the overall exergetic efficiency varies in the range of 19 to 26.5%. The components of EFGT generator show high exergetic efficiencies, about 93% for air compressor and about 90% for GT, whereas the solar thermal system shows the poor exergetic performance of about 17%. Based on economic analysis of the proposed plant, the effective price of electricity is estimated as 0.068 USD/kWh without any subsidy, but considering 50% capital subsidy the price is estimated as 0.04 USD/kWh. The discounted payback period is found to be 10.8 years without any capital subsidy, but when 50% subsidy is considered, the payback period is reduced to 5 years.

“…However, inadequate cold storage facilities in agricultural-based countries cause huge food loss (Sadi & Arabkoohsar, 2020), increasing the market price of the products significantly (Gardas et al, 2018). The need for cold storage is also increasing progressively, with growing food production and consumption worldwide (De & Ganguly, 2019a, 2019b. In developing nations like India, there are more than six thousand cold storage facilities operating presently to preserve agricultural products (Ganguly & De, 2018).…”

The Ministry of Maritime Affairs and Fisheries, Republic of Indonesia, urges economic stakeholders to maximize increasingly open export opportunities. With an abundance of fishery products in Indonesian waters, it must be supported by adequate facilities, one of which is the availability of cold storage, which maintains the quality of fishery products. In this study, the design of the cold storage was carried out by measuring the size of the cold storage and using the calculation of the cooling load, the calculation of cooling capacity, the calculation of the P-h diagram, and the cost estimate. The results of this study include cold storage design dimensions of 420 m3 with a long length and tall of 15×7×4 m3 made from insulation materials of polyurethane, stainless steel, and plaster. The cooling load data for the cold storage, when the product (tuna) is cooled and filled, is 3,707,444.3 kJ every 24 hours. A ton of refrigeration absorbs 12,660 kJ per 24 hours, equaling 16.3 tons of required refrigeration capacity. Meanwhile, under normal operating conditions, the total cooling load is 759,427.588 kJ per 24 hours. After calculating the cooling load, it was discovered that the initial design, which only had a capacity of 10 tons during the refrigeration process, could accommodate a cooling capacity of up to 16.3 tons. The cooling capacity of cold storage is 23.9 kW or 81.400 Btu/h. P-h diagram calculation of compressor cooling load is 0.7 kW, and the cooling load total from the evaporator to keep air room temperature of cold storage 0 °C is 0.43 kW. Estimated cost total for materials of cold storage design is USD 128,655. Highlights Refrigerator facilities are still limited in reaching remote coastal areas The cooling system must start using renewable energy Cold storage is used to maintain the quality of fishery product so that they remains in good condition From the calculation results, knowing the total cooling load when the cold storage is working, knowing the total cooling capacity of the cold storage when it is used as a fish storage refrigerator, and knowing the total estimated operational costs of the cold storage

Postharvest losses and spoilage of agricultural products are a major problem for tropical countries, and it is even more challenging for countries encountering fluctuating power shortages, such as Pakistan. Therefore, this study focused on the energy and economic analysis of cold storage to store three products (potatoes, pomegranates, and potatoes) according to the season and storage span throughout the year. The cooling load of the cold store was supported by a LiBr‐H2O vapor absorption and vapor compression refrigeration system to maintain the desired temperature for each product during cold storage. A solar thermal PV system is installed to operate cold storage refrigeration systems. Cold storage performance was analyzed by developing thermal models of integrated systems using the ambient conditions of Lahore, Pakistan. A parametric study was also conducted to analyze the impact of various working parameters on integrated system performance, and it was found that the maximum peak cooling load of 91 kW inside cold storage is attributed to pomegranates owing to high ambient conditions during its loading month. The product loading rate significantly affects the cooling load of cold storage and varies directly with it, as observed for an increase in the product loading rate from 0 to 50 000 kg/day cooling load also increases from 34 to 87 kW. To meet the thermal demand of the generator of the vapor absorption system, parabolic troughs were installed to operate cold storage, and it was found that a minimum of four PTC were needed to support the peak cooling load at the maximum product loading rate and minimum DNI value. To meet the electrical demand of cold storage electrical equipment and the compressor of the vapor compression system, solar photovoltaic panels were installed, and it was found that a minimum of 618 panels was required at a minimum tilted radiation value. To validate the viability of proposed design system economic analysis was also conducted which revealed a payback period of 12 years for Kinnow and potatoes and 16 years for pomegranates.
