The EPA defines refrigerant reclamation as "Reclaim refrigerant means to reprocess refrigerant to at least the purity specified in appendix A to 40 CFR part 82, subpart F (based on AHRI Standard 700–1993, Specifications for Fluorocarbon and Other Refrigerants) and to verify this purity using the analytical methodology prescribed in appendix A ...
It serves as the voice of the cold chain industry. The International Association of Refrigerated Warehouses (IARW) and the World Food Logistics Organization (WFLO) have a history of serving the food industry through the twentieth century and the impressive development of refrigeration in the movement of food products.
Food processing and cold storage: Equipment to preserve, process, and store food from its source to the wholesale distribution point: R-123, R-134a, R-407C, R-410A, R-507: Industrial refrigeration: Large equipment, typically 25 kW to 30 MW, used for chemical processing, cold storage, food processing, building, and district heating and cooling
A new twist on this technology uses ice as a condensing medium for the refrigerant. In this case, regular refrigerant is pumped to coils where it is used. Rather than needing a compressor to convert it back into a liquid, however, the low temperature of ice is used to chill the refrigerant back into a liquid. This type of system allows existing ...
Yakhchāl of Moayedi, Iran. A yakhchāl (Persian: یخچال 'ice pit'; yakh meaning 'ice' and chāl meaning 'pit') is an ancient type of ice house, which also made ice.They are primarily found in the Dasht-e Lut and Dasht-e-Kavir deserts, whose climates range from cold (BWk) to hot (BWh) desert regions.
Food storage building with chillers. A cool store or cold store is a large refrigerated room or building designed for storage of goods in an environment below the outdoor temperature. Products needing refrigeration include fruit, vegetables, seafood and meat. Cold stores are often located near shipping ports used for import/export of produce ...
In a snow storage frozen water (snow and/or ice) is saved in some kind of storage (pile, pit, cavern etc.). The cold is utilized by pumping melt water to the cooling object, directly in a district cooling system or indirect by a heat exchanger. The lukewarm melt water is then pumped back to the snow where it gets cooled and mixed with new melt ...
Some systems deal with flash-gas by separating it from the refrigerant that goes to the evaporator, as that portion of the refrigerant already evaporated and will only increase superheating. [6] One key feature when preventing flash-gas is the diameter of the piping. If the pipes are too thin and long, loss of pressure and friction tend to occur.
