Choosing the Right Kind of Compressor for Your Refrigeration System

A compressor is the heart of a refrigeration unit. It has to be efficient and should last long. Friga Bohn refrigeration products and compressors last long and the compressors of the company have exceptional quality and reliability. RefComp compressors manufacturers also produce a wide variety of reliable compressors that are used in residential, commercial and marketplace settings. The compressors should be chosen on the basis of their capacity. 

Below are the different compressors detailed on the basis of their capacities.

The cooling process can use any of the 5 compressors

Piston compressor: 

The compressor has a piston that runs back-and-forth. The piston compressors are preferred for applications below 10 tons. They can also be used for the 10 to 20-ton applications as they provide for better cost efficiency.

Rotary compressor: 

The compressor consists of a central rotor that rotates within the cylinder. Rotary compressors are used for smaller applications that are mostly employed in the residential settings. They offer good features when used for applications below 5 tonnes.

Scroll compressor: 

This compressor consists of 2 parts that have the shape of a spiral. One of the spirals has fixed position while the other has an orbiting motion.

Screw compressor: 

This compressor has 2 rotors having the shape of a screw. One of the screws is termed as male screw and the other as female screw. The screw compressors are quite popular for the refrigeration systems used in the large industrial and commercial markets. They have a wide capacity range that can vary from 20 to a greater of 750 tons.

Centrifugal compressor: 

This compressor has a multi-blade impeller that works at high speed. The centrifugal compressors are used in the largest of refrigeration systems. They are used in systems that have more than 150-ton capacity. The maximum capacity of these compressors can be up to 10,000 tons, but some can have a custom built application capacity of even 2000 tons.

Choose a compressor on the basis of its capacity. While investing in a compressor having a larger capacity than required can cause loss of money and higher energy bills, the use of smaller compressors may not provide adequate cooling. RefComp compressor manufacturers offer you product details that can help you chose the best compressor, and you can also reach the customer services department of the company to get the precise recommendations.

Characteristics of Air Volume Control Dampers

Air dampers increase the efficiency of an HVAC system. The different kinds of dampers in use today include the manual or motorized fire damper, duct damper and the volume control damper.

The air-volume control dampers are used to having a more accurate and precise flow of air within the HVAC or the Heating, Ventilation and Air Conditioning systems. The better volume control dampers have a long life, good tensile strength and specific designs for precise and system-friendly applications.

Shapes Of Volume Control Dampers 

The air volume control dampers control the air flow and consequently the air pressure, within an HVAC system. They should have the right size for a given air condition application. These dampers are produced in rectangular, square and round sizes. 

The rectangular dampers are used in 2 different forms. These include the “opposed-blade” and the “parallel” dampers. The blades of an opposed blade damper move opposite to each other.  The blades of a parallel blade damper are located parallel to each other and move in a single direction.  

The 2 Categories Of Air Volume Control Dampers
The air volume control dampers can be used in the exhaust, intake/supply or the mixed kinds of air applications of an HVAC system. The 2 categories of control dampers are the balancing and the commercial control dampers.

1. The Balancing Dampers
The balancing dampers regulate the air flow, but they do not provide for automatic control or shut-off. The manufacturers of these dampers also provide you with the hand-quadrants that can be used for installing and locking these dampers in their respective places.
Some balancing dampers also have the remote control feature. They can be operated remotely on a wall plate or at a diffuser. These remotely balanced volume control dampers are used in areas where the dampers could not be easily accessed, and their manual adjustment is not possible.
 

2. The Commercial Control Dampers
The commercial volume control dampers have the positive shut-off and the automatic control feature. So they do not require a manual operation, but their operation is quite similar to the operation of the manual balancing dampers.

Blades
The blades of a volume control damper can be made of stainless or galvanized steel. The blades of the damper should be symmetric at their axis-points. Symmetrical damper blades offer the same kind of operational characteristics, which is not dependent on the direction of the airflow. Hence, the dampers can be easily mounted in any of the flow directions, and the feature is advantageous in conditions where space is less.

What You Need to Know about the Pre-Insulated Ducts

The pre-insulated ducts offer great cost efficiency. They can retain greater heat and hence help you to save on your energy and electricity consumption costs. The ducts use the rigid kind of polyurethane foam and are laminated on either of their sides with an aluminum foil. Polyurethane is chemically and physiologically inert and is also un-soluble.

The foam pre-insulated ducts are a better alternative to the older sheet-metal ductworks.

Benefits of pre-insulated ducts
The ducts are light in weight. They can be very easily installed in any room or zone. Their installation is also quite cost effective and requires the least of time.

No air leakage
Pre-insulated ducts help prevent any kind of air leakages. They hence improve the efficiency of your HVAC or heating, ventilation and air conditioning system and provide you an efficient system that runs in an optimal manner, for decades to come, with least of maintenance.

No sweating
The insulation provided in the ducts is of greatest of density. The system is hence devoid of any kind of sweating.

Clean and hygienic
The modern pre-insulated ducts do not contain any kind of fibrous materials. Hence, any kind of dirt and filth cannot attach itself to the systems. They are quite improved with respect to their hygienic aspects as well. The ducts can also resist any kind of fungal growth and offer clean and hygienic air to all areas.

Cost saving
The efficient pre-insulated ducts help in saving of costs related to electricity. You can save up to 30% on your energy bills by integrating them into your HVAC system.

The ducts are now available in almost all kinds of sizes. They can hence be integrated with any kind of ducting system of an HVAC unit.

Pre-insulated ducts offer a number of advantages. Leading and renowned suppliers of perforated ceiling diffusers in Iran like Bin Dasmal can provide you with best pre-insulated ducts. They are a great innovation and can be used for hygienic and clean air supply.

Different Types of Ductworks Available Today

Apart from the condensers, refrigerants and compressors, the HVAC and the central air conditioning units also have a ducting system that carries the modulated or the cool air from the central air conditioner to different parts of your homes or individual rooms. Apart from cooling, ducts are also used for filtering air, for ventilation purposes and for providing heated air. There are different kinds of ductworks available today, as offered by the duct manufacturers in UAE.

Rigid Ducts

Rigid ducts are made up of a range of materials, and they can have a rectangular or a cylindrical shape. They also have an insulated covering in most of the cases. These ducts are quite reliable and have good endurance. 

Some of the rigid ducts in use today include:

The sheet-metal ducts: 

These ducts do not have a porous surface and hence, do not provide for mold growth, which makes them more hygienic. They can be made up of aluminum or galvanized steel. They have a lightweight and can be easily installed.

Fiber-board ducts: 

These ducts use the fiberglass strands in their built. The strands are first compressed and then bonded with a resinous material. A laminate foil and sheet protect the ducts from the adverse impacts of moisture. The ducts have a rough kind of surface that can adversely affect the efficiency of air flow. They are also breeding grounds of mildew and molds and are hence not recommended for the ventilation purposes.

The fiberglass line ducts:

These ducts, as provided by the duct manufacturers in UAE, are most often used in the commercial buildings and offices, as they dampen and lower the sound that is caused by the air-conditioning units. They have an external or internal lining of fiberglass. With time, the fiberglass material may get deteriorated and can cause the release of particles of fiberglass in the modulated air, which is a health concern. These ducts cannot be easily cleaned.

The Flexible Ductwork

The flexible ducts cost less than the rigid ducts, and they are also easy and fast to install. These ducts have the shape of a tube. Their built consist of wire that is covered with durable and bendable plastic. The whole duct is also surrounded by insulation material. These ducts are often deployed at the trickier of spaces where the rigid kinds of ducts cannot be installed. These ducts need good support and should also be well secured.

A reliable MEP contracting company in UAE, like Bin Dasmal, can provide you the best ducts for your needs and requirements. With extended warranties and best-in-class aftercare service, your satisfaction and security are ensured.

Dirt Streaking: Sources, Causes, Effects And Solution

All kinds of supply vents, including the supply ceiling diffusers of your HVAC unit, can suffer from dirt accumulations. Many HVAC maintainers and professionals have to face the problem of dirt affecting both inner and outside areas of a ducting system. Apart from diffusers, the registers and grilles are also affected by the dirt and debris issue.

The sources of dirt streaking
Dirt streaking can be caused by the turbulent air that comes out of the air supply vent. The air leaving the supply vent comes out with great velocity, as it gets squeezed through vent’s louvers. The dirt particles, that the air contains, also become entrained and are deposited on the surfaces through which the supply air blows.

Sources of dirt particles
This dirt that comes out of the supply ceiling diffusers comes from mainly 2 sources.  It can come from the room or zone itself. The room air contaminants include candles, carpeting, people and pets, among others. The second source of the dirt particles is the unsealed openings. The sub floor or the drywall can have these boot penetrations that can form the unsealed openings. Particles get pulled towards space and get absorbed into the airstream.

Apart from these dirt causative factors, other conditions can also amplify dirt streaking. High amounts of room moisture can cause stickiness in the dirt particles, and they can get settled and get accumulated easily. Even when there is no moisture, then also the dirt particles get attracted towards the surfaces of the buildings. There is also the Coanda effect.

Solving dirt streaking
If the ducts, coils and the HVAC equipment are clean, then air streaking gets reduced quite substantially. There is no duct leakage and issues related to filter bypass. Now dirt streaking can be only caused by the sunsealed boot penetrations or by the particles that are present in the room itself.

If the sources of dirt are external, then vent penetration will have the “anti-smudge” rings. If the sources of dirt are internal, then the boot penetration should be sealed so that there are no gaps.  The UI classified fire dampers are a used so that the dirt build-up caused fire can be effectively controlled. Dirt, filth and debris can have great negative effects and are even causes of the fire. Hence, issues relating to the area should be solved immediately.

What You Need to Know about Glass Wool Insulation

Glass fibers are used for making the glass wool insulation in UAE material. The glass fibers are made by using a glass wool binder and the resultant mixture of materials, which resembles wool. Through the process, a number of small air pockets are included within the fiberglass. The thermal insulation property of the material is because of these air pockets. Glass wool can be easily applied to any surface, for imparting its thermal insulating properties. It can also be sprayed on the surface, for attaining the same insulation benefits.

How Is Glass Wool Manufactured

Recycled glass and natural sand are mixed with each other at a temperature of around 1450 degree Celsius. The glass, thus produced is then converted in the form of fibers. Centripetal force is used for creating a fine mesh of particles, which are then cooled when they come in contact with air. A binder is added to the material, which holds the fiber material together and also imparts it with mechanical and cohesive strength. The fiber mat is subsequently heated at a temperature of 200 degree Celsius, which polymerizes the resins. At the last stage of glass wool processing, the wool is packed in the form of rolls/panels, under higher pressure. The end, or the finished product is then palletized, so that it can be easily stored or transported.

Uses Of Glass Wool Insulation In UAE

Glass wool insulation in UAE is used for providing insulation property to a number of materials like curtain walls, ceiling tiles for cavity wall insulations and for ducting insulation. They are hence used for insulating the ducts of HVAC or heating, ventilation and air conditioning units that provide for air modulation in homes and commercial settings. They are also used for insulating pipes in the plumbing systems, so that they do not produce uncomfortable levels of sound. The plumbing systems that are used in offices and other commercial areas, and homes, may use glass wool for the purpose of sound damping. PPR pipes fittings suppliers also supply high-quality glass wool materials. As fiberglass wool can resist all kinds of molds growth, it is a more hygienic insulation material as well.

The Benefits of AC Duct Cleaning

The professional services which are associated with HVAC and AC duct cleaning use brushes, vacuums and some kinds of chemicals for cleaning the ducts, and for scrubbing the interiors of the HVAC coils and the air-conditioning ducts. Duct cleaning holds a number of advantages for a home or building owner. 

Hygienic air

Indoor air pollution can occur from multiple sources, and these include the dirt and debris that come inside the homes through various agents. Pet dander can also pollute inner room air. This dirt gets accumulated inside the ducts of air conditioners and HVAC units and is then consequently rotated, thereby making the inner home air unhygienic and allergy-causing. Hence, the duct cleaning process ensures that you always get fresh air, which is fit for human respiration.

Better efficiency

Dirt and filth lower the efficiency of your air conditioner or HVAC system. The compressor and the motor have to work more in order to modulate the dirt-laden air, and the filth is also bad for the health and life of air conditioning and HVAC equipment. Duct cleaning services enhance the life of your air conditioner and HVAC units and make them more efficient as well.

Cost effectiveness

A well maintained HVAC unit and air conditioning system, which has properly cleaned AC ducting, uses less energy for its operation, as there is no unnecessary burden affecting the system components.
