| refrigerant compressor |
component of a refrigerating system which
increases the pressure of a compressible refrigerant fluid and simultaneously
reduces its volume, while moving the fluid through the device. See also
compressor |
| | |
| refrigerant cylinder (gas bottle) |
cylindrical steel pressure vessel with operable
closure for the storage and transport of refrigerant. |
| | |
| refrigerant distributor |
device used in conjunction with a thermostatic
expansion valve to ensure equable refrigerant distribution from the valve to
individual parallel sections of an evaporator |
| | |
| refrigerant flow rate |
mass flow rate of refrigerant pumped or moved
through a system at specified temperature and pressure. |
| | |
| refrigerant heat rejection |
total useful capacity of a refrigerant condenser
for removing heat from the refrigerant circulated through it. |
| | |
| refrigerant hydrolysis |
splitting of refrigerant compounds by reaction
with water; e.g., reaction of dichlorodifluoromethane or methyl chloride with
water, forming acid products |
| | |
| refrigerant metering device |
device which controls the flow of liquid
refrigerant to an evaporator. |
| | |
| refrigerant pressure-imposing device |
device or portion of equipment used for the
purpose of increasing refrigerant pressure. |
| | |
| refrigerant pump-out system |
dedicated apparatus for transfer of refrigerant
from a chiller or other refrigerating system to a separate and distinct storage
vessel. |
| | |
| refrigerant receiver |
vessel in a refrigerating system designed to
ensure the availability of adequate liquid refrigerant for proper functioning
of the system, and to store the liquid refrigerant when the system is pumped
down. |
