Fluorine refrigeration unit for for large fruit cold storage
Sunicorn headquarter is located in Shenzhen city, production and
R&D team is located in Shenzhen city and Kunming city in Yunnan
province.Our main products include all kinds of vacuum cooler, cold
storage room,ice maker etc.Company in the production of vacuum
pro-cooling equipment, large cold storage, refrigeration equipment
has been successfully applied in 12 provinces of China and other
professional engaged in the preservation of circulation and food
processing industry, a well-known enterprises, and has exported to
Malaysia, Singapore, Thailand, the United States, Mexico, Eastern
Europe and other places.And in the United States, California,
Florida and other places set up a firm and after-sales service
center. At any time to provide users with convenient and efficient
technical advice, maintenance and domestic and foreign parts
R22 belongs to a refrigerant restricted for use, with ODP=0.055 and
GWP=1500. As required by Montreal Protocol, R22 will be weeded out
gradually.R22 entered the freezing period in China in 2013. R22 has
approximate performance to ammonia refrigerant.
The performance of R507 or R404a is not as good as that of R22,but
the ODP of R507 and R404a is equal to 0,and the design pressure of
the refrigeration system is slightly high.
The recommend sequence of refrigerants is R22,R507 and R404a from
high overall system operation energy efficiency to low one.A
fluorine pump feeding refrigeration system mainly includes
refrigeration compressor unit,condenser,liquid receiver, low
pressure circulation tank, refrigeration shield pump,end
evaporator,etc. Auxiliary equipment including air separators, oil
collector,etc. Shall be set up in the system.
Scope of Application:
Applicable terminal evaporator forms:all forms such as air
Applicable to the case with drastic load fluctuation;
Applicable to the case where the feeding height or feeding
resistance of the refrigerating circuit is large and the direct
expansion feeding supercooling degree cannot meet requirements;
Applicable to the case where the end evaporator has no throttle
valve installation space(the valve must be installed outside the
storage and near the evaporator).
Without need to set up an active ammonia defense system;
Other advantages of the system are the same as those of the ammonia
pump feeding refrigeration system.
The fluorine refrigerant charging volume is large,the price of
refrigerant and refrigeration oil is high, the cost of the system
is higher than that of the ammonia pump feeding refrigeration
Fluorine refrigerant is an environmentally restricted refrigerant
for use and future system maintenance will be difficult;
The fluorine pump feeding refrigeration system shall be used with
caution especially for the refrigeration system with the terminal
Cold Storage Room Instruction:
The modular cold room series is an integrated family of sandwich
panels designed for quick cold room assembly. The panel
configuration has been reduced to a minimum, so the overall effect
is to offer the clients maximum design possibilities for cold rooms
with a minimum amount of panels required on the site. All products
from the modular range can be easily assembled without the need for
special tools. Likewise they can be dismantled easily in order to
move or enlarge them. The modular range has a wide variety of
applications from general food storage to mortuary chambers.
Material of the Cold Room:
A. Panel: polyurethane insulation foamed by high pressure, density above
B. Economical panel thickness: 50mm,75mm, 100mm, 150mm for choice.
C. STeel sheet: Painted galvanized steel.
D. Door: Convex door, hinge door and sliding door available.
E. Compressor: Copeland, Bitzer.
