Title:
ABSORPTION COOLING CYCLE USING LOW GLOBAL WARMING POTENTIAL (LGWP) REFRIGERANT
Document Type and Number:
Japanese Patent JP2018185139
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a system using a safer and environmentally-friendly refrigerant while suppressing a cost rise by solving a problem that usually, absorption cooling systems (absorption refrigeration systems) use ammonia/water and lithium bromide/water as working fluids, and due to the toxicity and flammability of ammonia and the corrosive nature of lithium bromide, such systems are typically used only in industrial environments, and a problem that as evaporators and absorbers are typically operated below atmospheric pressure, the equipment must be specially designed to work safely at low pressures, and this raises the cost of the systems.SOLUTION: An absorptive cooling system uses a refrigerant comprising one or more hydrofluoroolefin or hydrochlorofluoroolefin refrigerants, and an oil selected from the group consisting of a polyalkylene glycol oil, a poly alpha olefin oil, a mineral oil and a polyol ester oil.SELECTED DRAWING: Figure 2
