Different Types of Refrigeration Compressors

Compressors are essential in the vapor compression refrigeration cycle because they pressurize vaporized refrigerant from low pressure and temperature to high pressure and temperature before it passes through a condenser. While all compressors perform the same basic job in an industrial refrigerator system, they come in a variety of shapes and sizes, each with its own technique of creating pressure.

Compressors are being created in greater numbers and with better technology as the demand for refrigeration grows. The fundamentals, however, remain unchanged. It might be difficult to choose the right refrigeration compressor for your application because there are so many different models. Capital cost, operating efficiency, field serviceability, spare availability, and maintenance are some of the elements to consider while choosing the ideal unit. The numerous types of compressors as well as their key advantages and disadvantages will be discussed in the following sections.

Centrifugal

Centrifugal compressors also known as turbo or radial compressors, work by pumping refrigerant via a rotating impeller.

Centrifugal compressors have the highest capacity and are best for compressing large amounts of refrigerant. Additionally, depending on the application, centrifugal compressors can be set up in single, two-stage or multi-stage configurations to further compress the refrigerant to a greater pressure and temperature.

Rotary-Vane

Rotary vane compressors have an eccentrically positioned rotating drive shaft within a cylindrical enclosure with fixed inlet and discharge ports.

Rotary vane compressors are ideal for low-capacity applications such as domestic freezers or residential air conditioning units because of their small size and efficient operation. Rotating compressors, on the other hand, are frequently utilized in the food and beverage industry for product handling applications.

Rotary-Screw

Rotary screw compressors do not use mechanical force and do not have any valves, allowing them to run at high speeds with enormous flow rates and a small footprint while also decreasing vibration.

Rotary-Scroll

Rotary scroll compressors have a limited capacity of fewer than 20 tons, but they are extremely efficient due to the lack of pistons, allowing them to achieve 100% volumetric efficiency. Scroll compressors also produce less noise and require less maintenance since they have fewer moving parts.

Reciprocating

Reciprocating compressors are very scalable, allowing them to be constructed for modest capacities or large capacities in the hundreds of tons range. The main disadvantages of reciprocating compressors are their high noise level, excessive vibration, and inefficiency.

Common Causes of Air Conditioner Freezing Up

 There are many reasons why your AC unit may be freezing up. AC’s need proper airflow to keep the cold coil warm and a clogged air filter can impede the airflow causing an AC freeze. When your AC unit freezes up, it will quit cooling your home even though the blower continues to run.

As a leading AC products supplier, Bin Dasmal General Trading, a part of Bin Dasmal Group aims to support Oman based customers with high grade HVAC equipment along with general trading services, lifting supplies, access, and storage solution, contracting services and more. 

Here are some brief explanations of what causes the AC coil to freeze. 

• Dirty Filter 

The indoor coil is called the evaporator coil. When sufficient warm air is not pulled over the coil, it begins to freeze. Another cause for freezing could be when humidity in the air hits the coil, condenses onto the coil and freezes.

• Too many vents blocked 

The ducts in your air conditioner pull in warm, humid air and carry it to the air handler to be cooled and dehumidified. When the vents get blocked not enough air is circulated over the coils and its moisture starts condensing followed by a freeze.

• Thermostat set too low

Sometimes old air conditioners don't cool well, and the user may tamper with the thermostat. Most air conditioners are capable of cooling to about 62F. Lowering the temperature below that, it may simply get too cold and cause the moisture condensing to freeze.

•  Improperly Sized Ductwork

Ductwork that is too small for the AC and blower will restrict air from passing through the system to keep the coil from icing. On the other hand, ductwork that is too big doesn't allow air pressure for adequate airflow. This in turn causes an AC freeze.\

 

• Bad Blower Fan

If the blower motor is burnt out and makes a squealing sound it could indicate fan damage which restricts proper airflow. Airflow is a major reason for freezing an AC. You may need a technician to pinpoint the issue. 

• Low Refrigerant

Coil icing can also occur with low refrigerant. As the refrigerant level drops and lowers in temperature it causes the coil to get freezing cold. This freeze condensates as it removes moisture from the air.
