It is an indispensable part of the entire steering gear arrangement of ships and dictates the exact behavior of the rudder response

The ______________ is the heart of your refrigeration system. It is an air pump that compresses refrigerant gas and changes its state, which allows it to absorb heat. This process results in cooling, which is then distributed to your facility via your air ducts.

It occurs when moisture picked up by the refrigerant starts to freeze, building ice crystals that block the refrigerant passage in narrow passageways, for example in the expansion valve. This effect is called intermittent cooling, as the compressor stops after a while due to the blockage in the expansion valve.

What is the normal temperature of fruits and vegetable room?

Type of steering mode in which the ship will automatically find its way to preset position point along a preset route. If the ship is forced out of the course, the function of this mode will use the rudder to get the ship back to course.

This is the room in which the actuator is located. On the top of the actuator there is a scale with degrees showing the angle of the rudder port/starboard and also signal transmitters and feedbacks for remote rudder indication and steering gear control system.

The _____________ contains tubes and fins that absorb the heat from the refrigerant flowing through it, causing the refrigerant to evaporate. The vapors are then carried back to the compressor where they are compressed again and cooled, completing the cycle.

Parameters to be considered in operating a purifier, means the quantity of oil pumped into the purifier per hour.

The purpose of a ____________________ is to regulate the amount of liquid refrigerant entering the evaporator coil. This helps keep the pressure in your system at its optimum level, which prevents unnecessary costs and repairs.

Maintenance on purifier, which should be carried out every 4,000 operating hours or at least once every year.

The _________ connected in the system consists of silica gel to remove any moisture from the refrigerant

The ______________ is the part of a refrigeration system that absorbs heat from the air or other substance to be cooled.

Heat energy that causes a change in temperature (Joule).

It is the location of the main control panel the steering gear system. This control panel features start/stop control alarms, signals and ability to acknowledge alarms.

What are the four main components of the refrigeration system?

It is an equipment with the sole purpose is to clean the oil from water and solid particles. What do we call on this?

It is a component in Refrigeration system where it is commonly used for compressing and supplying the refrigerant to the system. Low-temperature vapor is drawn to it, where it is compressed into a high-temperature, high-pressure vapor

Rate of heat flow by either conduction, convection or radiation

As per standard requirement, the steering gear should be capable of steering the ship from 35 degrees port to ________ starboard and vice versa with the vessel plying forwards at a steady head-on speed for maximum continuous rated shaft RPM and summer load waterline within a time frame of maximum 28 seconds.

What is the means of removing impurities from fuel using purifier?

What do we call to this centrifugal separator for solid-liquid separation, which removes solids such as particles, oil, natural organic matter and color from processed liquid?

In starting Refrigeration system, how many percent is to be set on temperature control into MANUAL and adjust capacity control slide, otherwise compressor will trip on overload?

Ideal for testing on packages that contain liquids and that do not contain any air or have much headspace. Milk is often tested this way. Packages are placed in the chamber and it is subjected to a vacuum. An absorbent material such as paper towel is used and after the test, if the paper towel is moist, then the package is compromised.

Maintenance on purifier, perform complete separator every 18 months or 12,000 operating hours. Seals, bearings, and friction blocks are renewed.

One of the commonly used steering gear construction and is quite expensive in construction. The basic principle is same as that of a hydraulically-driven motor engine or lift.

Steering gear has smaller space required, low installation cost, less weight and smaller power required for the same load, because it can transmit pure torque to the rudder stock.

It is a metering device which is used to control the flow of refrigerant into the evaporator, or cooling coil, as a low-pressure, low-temperature refrigerant.

In Refrigeration system, what is the state of the refrigerant from evaporator going to the compressor?

The _______________ is an important part of a refrigeration system. It controls the flow of liquid refrigerant within the system. It also helps prevent overcharging and undercharging of your cooling system.

Acid content inside a system can emulsify with the compressor oil to form an aggressive oil dirt that reduces lubrication properties. This can lead to serious compressor damage. They can also cause a variety of other problems in a system, such as blockages of strainers, expansion valves and other tiny passages.

Maintenance on purifier, which consist of an overhaul of the separator bowl, inlet/outlet and operating water device every 4,000 operating hours or 6 months.

Refrigeration compressors that use pistons to move the refrigerant through a system of valves and chambers.

Steering mechanism is consist of two cylinders, a pump and a motor. The pump has a unidirectional variable displacement and constant speed flow.

The pressure at which a substance at any given temperature can exist in equilibrium with both its liquid and vapor states

Presence of this inside the refrigeration system causes starving of evaporator and rapid condenser pressure rise cause compressor short cycling and frosting of expansion valve inlet

HFO purification process wherein initial purification by gravity separation takes place. This also provides suction of fuel oil to the separator.

The temperature at which a substance reaches its boiling point.

Reciprocating single or two stage _____________ is commonly used for compressing and supplying the refrigerant to the system

Steering gear system which works by introducing pressure into the compartments formed between a stator fixed to the ships structure and a rotor attached to the rudder stock.

What do we call for the process by which the effects of gravity can be amplified by the use of centrifugal force to the extent that the separation process becomes rapid and continuous centrifuges work by rapidly spinning a bowl containing the liquid, thus producing the required centrifugal force to produce separation?

It’s a system that has the ability to cool and maintain temperatures within a given range. It’s usually mechanical but can also be achieved by using simple means such as using water or any other liquid to lower the temperature.

Presence of this inside the refrigeration system causes high condenser and compressor temperature, abnormally high discharge pressure, jerky pointer gauge and very small bubbles in liquid sight glass.

Port state control has very strict on this. Many ships have been fined and detained due to such faults pointed out during port state control inspection.

The __________ unit act as a heat exchanger to cool down the hold or room area by transferring heat to the refrigerant.

Moisture can cause __________. However, moisture in combination with a HCFC refrigerant containing chlorine (like for example R-22 or R-409A) creates much more serious, as the chlorine hydrolyses with the water to form hydrochloric acid (HCl) which is aggressive to most metals.

How to troubleshoot a purifier, when the rectangular ring in the operating slide or bowl body is defective?

This is a very efficient way to test packages that have some air or gas in the package. These package are submerged in a leak detecting equipment that contains water and uses a vacuum to see if there are leak, then the package is faulty

It is a component in Refrigeration system wherein this process, as heat is removed from the vapor, a change of state takes place and the vapor is condensed back into a liquid, at a high-pressure and high temperature.

It is the most important aspect of any refrigeration circuit and ensures that your circuit is hermetically sealed.

The ________________ coils in a residential or commercial air conditioning system usually contain a refrigerant called R-22, which was developed for use in these systems. R-22 has been banned by EPA because of its high global warming potential (GWP), but some older systems still use it.
