Identification Flashcards
(15 cards)
it is the amount of heat absorb by circulating refrigerant in the evaporator coil of the refrigeration system.
Refrigerating Effect
It is the widest manufacture type of refregiration unit applicable to both chilling and freezing process of the product being refrigerated.
Vapor compression refrigeration cycle
It is used to decrease pressure of a fluid in a vapor-compression refrigeration cycle.
Expansion Valve
The ratio of refrigerating effect to the work of compression.
Coefficient of performance
The energy rate to compress the refrigerator vapor allowed to power input to the compressor
work of compression
The amount of heat needed to raise the temperature of one kg substance by one degree centigrade.
specific heat
The heat added to or removed from a substance that can be measure by the change in temperature
Sensible Heat
The heat added to or removed from a substance to cause a change of state without a change in temperature
Latent Heat
It is the primary working fluid used for absorbing and transmitting heat in refrigeration system
Refrigerant
One of the naturally occurring compounds is collectively known as “natural refrigerant”. It is non-flammable and nontoxic, with no known carcinogenic, mutagenic, or other toxic effects, and no dangerous products of combustion.
Carbon Dioxide
Refrigerants, which are designated by number 7, followed by the molecular weight of the refrigerant (round off)
Inorganic Refregirant
A rotary compressor that uses rotating elements like a pair of screw inside stationary cylinders. These pair of screw provide positive displacements of gases on the discharge port of the compressor.
Screw Compressor
A type of compressor whose motor and compressor are often enclosed in the same housing or common housing to avoid leakages at the seal.
Hermetically Sealed Compressor
It is the minimum possible volume in a reciprocating engine pump that is usually occurs at the farthest position of the piston.
Shell and Tube heat exchanger
It has a stationary casing cylinder, a rotor or roller, which is a rotating element, a spring-loaded vane which is always in touch with the rotor, the intake port and the discharge port.
Roller or single vane compressor
