About Container Refrigeration Unit
A reefer container is an encased unit used for delivering temperature-fragile cargo. The container requires an external power supply for its movement. The article portrays all that you anytime required to know about container refrigeration units.
Exactly when reefer containers are stacked in ships, the power supply is given from the powder made from the D.G sets of the vessel. If the vessel's generator limit isn't adequate to help the additional power usage of the refrigerated containers (assuming there ought to emerge an event of old boat or unavailability of the generator due to redesigning, etc), adaptable power packs are presented on the boat.
There is a substitute grouping of refrigerated conveyance containers present in the market today. A particular kind is used depending on the efficiency needed and the cargo they need to convey.
1. Close Reefer: This is a common sort of refrigerated container. It comes in one piece with a fundamental front wall and an all-electric customized cooling and warming unit for ISO sea containers.
2. Changed/Controlled Atmosphere (MA/CA) reefer containers: These sort of safeguarded transportation containers keep a consistent air by superseding consumed oxygen using an air exchange structure, keeping an ideal environment in offset with the thing's breaking down rate.
3. Customized Fresh Air Management Containers: Popularly known by their contraction - AFAM reefer containers use state-of-the-art development to coordinate the air blend thus changing the size of regular air exchange. It works like a Controlled Atmosphere refrigerated container, controlling the production of oxygen, carbon dioxide, and others. The controls of the AFAM refrigerated containers can be changed as per influence and expand the time frames of ease of use of the cargo they convey.
A couple of critical concentrations of container refrigeration are:
Reefer containers for rent and sale is fitted before the container and it fills in as a container front wall.
A couple of units are twofold voltage, expected to deal with 190/230 or 380/460 volts A.C, 3 phase, 50-60 hertz power.
Working control power is given by a single-stage transformer which steps down the A.C supply power source to 24 volts, 1 phase control power.
Understanding the Basic Sections of Refer Unit
1. Blower Section
Includes a blower (with H.P switch) and power connect limit compartment. Power transformer may be a decision where the boat supply changes.
It moreover contains directing and attractions solenoid valve (for controlling how much gas stream).
Security fittings in the part are moistness liquid pointer, pressure easing valve, channel drier, etc.
Security of the structure is furthermore overhauled by electronic seeing with the help of the following sensors-Compressor pull and delivery sensor, supply air temperature sensor, supply recorder sensor, and encompassing sensor.
2. Condenser Section
The condenser region contains a condenser fan and its motor, an air-cooled condenser circle, and a condenser submersion sensor.
For an air-cooled condenser, the air is commonly gotten from the base and delivered equally through the point of convergence of the unit.
A couple of units include a water-cooled condenser/gatherer. This unit is expensive.
3. Evaporator Section
This section contains a temperature distinguishing bulb, a return recorder bulb sensor, and a thermostatic expansion valve (for a stream of refrigerant and upkeep of inside temperature).
The gathering includes evaporator twist and hotter, channel skillet and radiator, defrost, and warm transmission switches.
The evaporator fan courses air all through the container by pulling air on top of the refrigeration unit and planning air through the evaporator circle where it's either warmed or cooled and is then delivered out at the lower part of the refrigeration unit into the container.
4. Outside air Make up Vent
The justification for this vent is to give ventilation to items that expect outside air dispersal and ought to be closed while transporting frozen food sources.Air exchange depends on static strain differential which will change depending upon how the container is stacked.
