Marine air cooled refrigeration plant is a refrigeration unit after several years of continuous technical improvement, carrying the technology security and innovation; it is direct refrigeration unit takes refrigerant as cooling medium. Marine refrigeration plant is important equipment of ships, oil platforms food cold room refrigeration system, the temperature can be adjusted according to the requirements of food preservation, to satisfy the food fresh keeping requirements. Especially the explosion-proof design and treatment will broaden the application range, it can be used in the environment with flammable and combustible gas, this refrigeration plant has features of new design, smart control, convenient operation, energy saving, reliable running, reasonable safety precautions and so on. It can be widely used in various passenger ship, cargo ships, naval vessels and oil platforms.
CZLZ (F) -3~74 marine air cooled refrigeration plant
“Z”： packaged type
“LZ”： refrigeration plant
“F”： cooling method is air cooled, if unit is explosion0proof type, F is represented by B
“74”： nominal cooling capacity is 74KW
marine air cooled refrigeration plant is mainly composed of marine air cooled refrigeration unit, electric control box, valve plates, air cooler. Marine air cooled refrigeration unit is composed of two refrigeration compressors (one for refrigeration, one standby), two air cooled condensers, two liquid receivers, two gas-liquid separators, two dry filters, safety protection device and other parts; all parts are installed on a common base; there is one valve plate, mainly composed of thermal expansion valve, solenoid valve, stop valve, evaporating pressure control valve.
Marine air cooled refrigeration plant is mainly used in all kinds of naval vessels, ships, marine platforms where food preservation is needed, it provides cold source for cold rooms, mainly used to maintain the temperature required by food preservation, keep food fresh.
Marine air cooled refrigeration plant sets all functional components in one, it has the advantages of convenient and simple operation, compact structure, low energy consumption, low noise, shock and swing resistance, convenient maintenance etc. The refrigeration plant automation degree is high, cooling capacity is large, speed is fast; the high level electric control automation will reduce operators’ labor intensity and reduce energy consumption; all heat exchange components adopt copper material, the corrosion resistance is strong, ensure the equipment effective operation time. Marine air cooled refrigeration plant adopts air cooled condenser, cooling water isn’t needed in runtime, water pump and water pipe can be removed in operation, save the installation space. The design, manufacture, delivery of refrigeration plant is conducted according to the standard of classification societies (such as “CCS”, “ABS”, “NK”, “DNV”) and “navy”, and it can be manufactured according to customer’s actual demands.
· cooling capacity：3kW～74kW
· Refrigerant: standard equip R404A, R22、R407C can be selected
· Power supply: standard equip AC 3PH 380V/50Hz, AC 3PH 440V/60Hz, other power source can be selected if it is needed: AC 3PH 415V/50Hz, AC 3PH 460V/60Hz, AC 3PH 480V/60Hz, AC 3PH 690V/60Hz.
· Compressor: piston type （open or semi-hermetic or hermetic type）, screw compressor can be used if cooling capacity is large, standard equip Bitzer compressor, BOCK、Carrier and other brands can be selected.
