Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
A substance used for refrigeration.
- ‘Chlorofluorocarbons were developed and used as refrigerants, blowing agents for polyurethane foam, and propellants in spray cans.’
- ‘For example, chlorofluorocarbons have been used in the second half of the 20th century as nonflammable refrigerants, industrial solvents, foaming agents, and aerosol propellants.’
- ‘In addition, conventional air conditioners use refrigerants made of chlorine compounds, suspected contributors to the depletion of the ozone layer and global warming.’
- ‘Many products, such as refrigerants and solvents that have been developed over the past 50 years, used substances called chlorofluorocarbons (CFCs).’
- ‘Instead of using water, these new machine guns will use modern refrigerants to keep the gun's barrel cooled in a closed system that could be used on armored vehicles and static positions.’
- ‘Replacement refrigerants have now been developed which are less harmful to the ozone layer.’
- ‘My example of an immediate man-made global environmental crisis is the one created by the profligate use of chlorinated-fluorocarbon refrigerants - the gas used in refrigerators.’
- ‘An expansion valve would then advance to transform the liquid refrigerant into a cold, gaseous form, so as to once again absorb the warm air inside your automobile.’
- ‘Formic acid is also used in fumigants, refrigerants, solvents for perfumes and lacquers, brewing, and silvering glass.’
- ‘The warm, gaseous refrigerant is sucked from the evaporator into the compressor, where the pressure is raised to the condensation pressure of the refrigerant in order for the phase change to occur.’
- ‘These new greener chillers use sound waves for cooling instead of environment-damaging chemical refrigerants linked to global warming.’
- ‘We've removed a fair bit of heat from the refrigerant - it's now a high-pressure liquid at roughly ambient temperature.’
- ‘In the last half of the twentieth century, the manufacture of chlorofluorocarbons for use as propellants in aerosol sprays and refrigerants has resulted in a slow mixing of these compounds with the stratosphere.’
- ‘The old chlorofluorocarbon refrigerants, or CFC's, that were shown to be harmful to the ozone layer have not been installed in new refrigerators since 1993.’
- ‘Some of the green features of this facility are raised floors, insulated glass, gas-fired absorption chillers using water as a refrigerant, a dehumidification system and efficient lighting.’
- ‘However, he points out that halogen oxidants also form during the sunlight-triggered breakdown of industrial chemicals such as chlorofluorocarbon refrigerants.’
- ‘Today, key commercial uses of liquefied gas include liquefied refrigerants for cryogenic application and liquefied petroleum gases for fuel use.’
- ‘Oakhurst became the first major company in the region to use non-chlorofluorocarbon refrigerants in all of its fleet.’
- ‘In addition to controlling pressure, fluid-control valves regulate the rate the flow of fluid i.e. how brake fluid, transmission oil, refrigerants and other fluids are used in the car.’
- ‘The company now promises to switch all of their cooling units to environmentally friendly refrigerants by 2004.’
Causing cooling or refrigeration.
- ‘Carrying the heat energy away, the warmer (but still fairly cold) refrigerant vapour is sucked back into the compressor and the cycle begins again.’
- ‘So there's a vast range of applications which these refrigerant gases are being used in.’
- ‘The radiator has an upper space which provides communication between the first passage and the second passage, whereby the refrigerant vapor is guided to flow preferentially into the first passage.’
- ‘The heat pump uses similar technology to a domestic fridge - the expansion and contraction of refrigerant gases to produce much more heat using less electricity.’
- ‘Liver damage found in nine workers is believed to be caused by a leaking refrigerant pipe in the workers' cabin.’
- ‘This is accomplished by providing a regulated flow of ambient air about the feed assembly in conjunction with a vacuum assembly which is used to remove excess refrigerant vapor from the gas diffusion chamber.’
- ‘The most common type is a refrigerant dehumidifier, which works on the same principles as a refrigerator or air conditioner.’
- ‘The circulating fluid in your air conditioner is a special refrigerant gas that is put in when the system is installed.’
- ‘We can also vary many controls for specific tasks such as monitoring refrigerant levels, for example.’
- ‘The cooler includes a variable displacement compressor for compressing refrigerant gas.’
- ‘The refrigerant fluid is ammonia dissolved in water.’
- ‘The action is diuretic, refrigerant and diaphoretic, and the juice extracted from the fresh plant is of use in urinary and kidney diseases.’
- ‘It performs a vital task of moving the liquid around the pipe. It pumps and forces the liquid or the refrigerant gas out from the evaporator where it absorbed the heat coming from the car's cabin.’
- ‘They have uses as propellants in aerosol spray cans, refrigerant gases, and foaming agents for blown plastics.’
- ‘Improper unit location, lack of duct insulation, improper duct sealing, and incorrect refrigerant charge can greatly diminish efficiency’
- ‘This is likely fallout from the Kyoto Protocol relating to refrigerant emissions.’
- ‘The fluid returns to the heat pumps, which utilize a refrigerant cycle to take the fluid's low quality heat and concentrate it; the process is reversed for cooling.’
Late 16th century (denoting a substance that cools or allays fever): from French réfrigérant or Latin refrigerant- ‘making cool’, from the verb refrigerare (see refrigerate).
