12 24v refrigerator compressor

Types of 12 24v refrigerator compressors

A 12 24v refrigerator compressor is a vital component of a refrigerator that facilitates the circulation of refrigerant metal to cool heat from outside the fridge. There are several types of refrigerator compressors that are commonly used in refrigerators. They include the following:

• Reciprocating Compressor: This is a popular type of refrigerator compressor that is used in most modern refrigerators. The reciprocating compressor functions of displace gases through the up and down motion of a piston that is driven by an electrical motor attached to it. The motor is connected to the crankshaft firmly which works to convert the rotational movement into linear movements that function to push the refrigerant through the tubing. This works to create space and suction for the absorption of heat in the refrigerator space. The high pressure at which the refrigerant gas is in the compressor enables it to release heat swiftly. This type of compressor can be used in both large commercial and small residential refrigerators.
• Semi-Hermetic Compressor: Just like the reciprocating compressor, the semi-hermotic compressor also uses the reciprocating principle to operate. However, this compressor has an open motor, meaning the electric motor is outside the compressor. Due to this nature, the compressor can be easily and quickly repaired and used with any type of refrigerant. This gives them a great advantage over the hermetic compressors which have the motor inside them.
• Hermetic Compressor: The Hermetic Compressor has the motor and compressor sealed tightly in a welded metal casing. This allows the refrigerant to flow freely with less energy loss in the system. The smooth flow of the refrigerant cools heat effectively, making it an appropriate choice for mobile and enclosed situations. The Hermetic system effectively and quietly compresses refrigerant, making it suitable for many air-conditioning and refrigeration applications.
• Centrifugal Compressors: These are the latest developments in refrigerator compressor technology. They work to convert the pressure of the refrigerant through the force of inertia and spinning. They are most suitable for large commercial refrigerators.

Specifications & Maintenance

The specifications of 12/24v refrigerator compressors may vary depending on the type, brand, and model. Here are some key refrigerator compressor specs to consider.

• Horsepower Rating

  This rating indicates the ability or power output of the compressor motor. It is usually measured in HP. Generally, a higher horsepower rating means the compressor will perform heavy-duty tasks.

• Physical Dimensions

  These show the typical size of a refrigerator compressor. They are presented in unit measurements like millimeters or centimeters. The dimensions may vary between models and types. For instance, small refrigerator compressors designed for 3-way camping fridges may have dimensions of 260 x 200 x 230 mm.

• Operating Voltage

  This specification indicates the voltage level a compressor requires to function as intended. The voltage level may affect the performance, efficiency, and suitability for specific applications. Some models operate well under 12v, while others under 24v.

• Cooling Capacity

  A refrigerator compressor's cooling capacity is the amount of heat the compressor is designed to remove from its surroundings within a specific time. This capacity is typically measured in BTU per hour or kilowatts.

• Energy Efficiency Rating

  Compressors are usually rated based on their energy efficiency. The rating shows how well the model converts electrical energy into cooling power while minimizing energy loss.

Maintenance

Like most mechanical systems, a refrigerator compressor requires maintenance to function well and for many years. Here are some fridge compressor tips to keep in mind:

• Users should operate the fridge compressor within the recommended pressure and temperature limits. This way, the system will maintain optimal performance.
• Debris or dirt can hinder ideal performance. For this reason, individuals or technicians should regularly clean the compressor to remove any disturbing material.
• Regularly inspect the compressor for early signs of damage or wear. Addressing the signs may prevent further damage or costly repairs. Typical signs to look for are unusual noises, vibrations, or leaks.
• Some 12/24v refrigerator compressors have oil for lubrication purposes. Check the oil level periodically and top it up as suggested by the manufacturer.

Usage scenarios of 12 24v refrigerator compressors

The job of a refrigerator compressor is to recycle the refrigerant so that it can continue to remove heat from the inside of the fridge. Without this important part, there would be no cold air inside the fridge, and perishable food would go bad. Here are some scenarios where a 12v compressor is used.

• Commercial business fridge

  A standard commercial business will need constant access to cold beverages and food. They will often need to stock more than a household will.

• Off-grid solar energy systems

  Solar panels will not produce enough energy for a fridge during the night. A 12v compressor fridge can work better with solar panels because it uses less energy than a 120v compressor fridge.

• Car fridge

  Even a small fridge can take up a lot of space and use a lot of power. A 12v refrigerator compressor is small and powerful enough to make the fridge cabinet cold so that food and drinks stay fresh. Battery-powered car fridges use 12v compressors, allowing people to store food while camping or on a road trip.

• Deep freezer

  The primary job of a deep freezer is to store food for a very long time, mostly in the winter months when the outside temperature is lower. Refrigeration compressors used in deep freezers must be powerful enough to freeze food at very low temperatures.

• Cold chain logistics

  Cold chain logistics is a method of safely transporting temperature-sensitive items, such as fresh food or certain medical supplies, which need to remain refrigerated. 12v refrigerator compressors can ensure that items remain at the right temperature, no matter how far the destination is.

• Vaccination storage

  Vaccines and medical supplies need to be stored in an exact temperature range to maintain their efficiency and to be effective when it is time for the patient to use the medicine. 12v refrigerator compressors can keep medical supplies at the required temperature even in areas with unstable electricity.

How to Choose 12 24v refrigerator compressors

Both business buyers and end consumers can consider the following factors when choosing the 12/24 compressor for their use.

• Matching Voltage Power Supply

  People do not want to invest in a refrigerator compressor that will not work with the power supply. Therefore, it is advisable to use a compressor that works with both 12 and 24 volts.

• Consider the Flash Rate

  p>Duty cycle is another term people may come across when researching the pulsing rate. It refers to the time the compressor runs and the time it falls short. The estimated average for DC compressors is around 45 to 60 minutes of run time and a 15 to 30-minute cutout. This fluctuating on and off pattern aids in conserving battery power.

• Think About Noise and Vibration

  Since most DC fridge compressors work silently, users want a silent-running model. The quietest models produce noise levels of up to 38 dB, which is about the same as ambient noise or leaves rustling. Installing the compressor on a rubber mat can absorb any vibration or noise that may occur.

• Evaluate Efficiency

  Opt for a compressor designed to operate in an environment with minimum friction and maximum sealing. Such designs enhance energy-saving performance, allowing users to extract more from the battery or power source.

• Deciding on Tank Size

  The size of the tank affects the amount of coolant that can be stored. More refrigerant improves system efficacy and permits longer compressor off periods. Users can select between smaller and larger tanks based on individual requirements, though a larger tank would usually be more economical.

• Sustainability

  People are becoming increasingly cautious about how their choices today affect future generations. With this in mind, it's prudent to choose a compressor that uses refrigerants, including R-600a (isobutane), which have minimal environmental effects.
