Yesterday we got some information about Time to Service Your Air Conditioning Unit, and now we will give your information about Refrigeration and Air Conditioning.

refrigeration and air conditioning

Refrigeration and air conditioning end-uses typically use a refrigerant in
a vapor compression cycle to cool and/or dehumidify a substances or space,
like a refrigerator cabinet, room, office building, or warehouse.

Chillers typically cool water, which is then circulated to provide
comfort cooling throughout a building or other location. Chillers can be
classified by compressor type, including centrifugal, reciprocating,
scroll, screw, and rotary. SNAP has identified substitutes for CFC-11,
CFC-12, CFC-113, CFC-114, R-13B1, HCFC-22, R-500 and other ODSs.
Chillers used to cool industrial processes are discussed under
Industrial process refrigeration systems.

Industrial process
refrigeration systems cool process streams in industrial applications.
The choice of substitute for specific applications depends on ambient
and required operating temperatures and pressures. SNAP has identified
substitutes for CFC-11, CFC-12, HCFC-22 and other ODSs.

Ice
skating rinks frequently use secondary refrigeration loops. They are
used by the general public for recreational purposes. SNAP has
identified substitutes for CFC-12, HCFC-22, R-502 and other ODSs.

Industrial
process air conditioning is distinct from commercial and residential
air conditioning. It is often used when ambient temperatures near 200
degrees Fahrenheit (93 degrees Celsius) and corrosive conditions exist.
Units in this end-use provide comfort cooling for operators and protect
process equipment. SNAP has identified substitutes for CFC-12, CFC-114
and other ODSs.

Cold storage warehouses are used to store meat,
produce, dairy products and other perishable goods. The majority of cold
storage warehouses in the United States use ammonia as the refrigerant
in a vapor compression cycle, although some rely on other refrigerants.
SNAP has identified substitutes for CFC-12, HCFC-22, R-502, and other
ODSs.

Retail Food Refrigeration includes all cold storage cases
designed to chill food for commercial sale. In addition to grocery
cases, the end-use includes convenience store reach-in cases and
restaurant walk-in refrigerators. Icemakers in these locations are
discussed under commercial ice machines. SNAP has identified substitutes
for CFC-12, HCFC-22, R-502 and other ODSs.

Vending machines are
self-contained units which dispense goods that must be kept cold or
frozen. SNAP has identified substitutes for CFC-12, R-502 and other
ODSs.

Water coolers are self-contained units providing chilled
water for drinking. They may or may not feature detachable containers of
water. SNAP has identified substitutes for CFC-12, R-502 and other
ODSs.

Commercial ice machines are used in commercial
establishments to produce ice for consumer use, e.g., in hotels,
restaurants, and convenience stores. SNAP has identified substitutes for
CFC-12, R-502 and other ODSs.

Household refrigerators and
freezers are intended primarily for residential use, although they may
be used outside the home. Household freezers only offer storage space at
freezing temperatures, unlike household refrigerators. Products with
both a refrigerator and freezer in a single unit are most common. SNAP
has identified substitutes for CFC-12, R-502 and other ODSs.

Residential
dehumidifiers are primarily used to remove water vapor from ambient air
for comfort or material preservation purposes. While air conditioning
systems often combine cooling and dehumidification, this application
serves only the latter purpose. SNAP has identified substitutes for
CFC-12, HCFC-22 and other ODSs.

Motor vehicle air conditioning
systems, or MVACS, provide comfort cooling for passengers in cars,
buses, planes, trains, and other forms of transportation. MVACS pose
risks related to widely varying ambient conditions, accidents, and the
location of the evaporator inside the passenger compartment. Given the
large number of cars in the nation's fleet, and the variety of designs,
new substitutes must be used in accordance with established retrofit
procedures. Flammability is a concern in all applications, but the
conditions of use and the potential for accidents in this end-use
increase the likelihood of a fire. In addition, the number of car owners
who perform their own routine maintenance means that more people will
be exposed to potential hazards. SNAP has identified substitutes for
CFC-12 and HCFC-22.

Residential and light commercial air
conditioning and heat pumps includes central air conditioners (unitary
equipment), window air conditioners, and other products. HCFC-22, a
class II substance, is the most common refrigerant for this application.
SNAP has identified substitutes for HCFC-22 and other ODSs.

Heat
transfer includes all cooling systems that rely on convection to remove
heat from an area, rather than relying on mechanical refrigeration.
There are, generally speaking, two types of systems: Systems with fluid
pumps, referred to as recirculating coolers, and those that rely on
natural convection currents, referred to as thermosiphons. SNAP has
identified substitutes for CFC-11, CFC-12, CFC-113, CFC-114, CFC-115 and
other ODSs.

Very Low Temperature Refrigeration systems require
maintaining temperatures in the vicinity of -80 degrees F (-62 degrees
C) or lower. Examples include medical freezers and freeze-dryers, which
generally require extremely reliable refrigeration cycles to maintain
low temperatures and must meet stringent technical standards that do not
normally apply to refrigeration systems. SNAP has identified
substitutes for CFC-13, R-13B1 (Halon 1301), R-503 and other ODSs.
