Condensers are one of the vital components in refrigeration and air conditioning systems. By converting refrigerant vapor into liquid, they complete the refrigeration cycle and provide the required cooling for various environments.
On this page of Tabadol Gostar Booran, we provide a comprehensive review of condensers. What a condenser is, the types of condensers available, and the application of each type in refrigeration industries. Stay with us to better understand condensers and make optimal use of these components in cooling systems.
A condenser is one of the main components in cooling and air conditioning systems, playing a critical role in the refrigeration cycle. Its primary function is to convert hot refrigerant vapor into liquid. This process occurs by transferring the heat absorbed by the refrigerant in the evaporator to the surrounding environment.
Simply put, the condenser removes excess heat from the system, allowing the refrigerant to return to a liquid state and repeat the refrigeration cycle. This phase change from gas to liquid is a key part of the refrigeration cycle and is essential for the proper operation of cooling systems.
The function of a condenser can even be compared to a radiator, which transfers system heat to the outside environment. As the refrigerant cools in the condenser, its pressure decreases, preparing it to evaporate again in the evaporator and absorb ambient heat. This continuous cycle of evaporation and condensation forms the basis of refrigeration systems, creating the required cooling in different environments.
If we want to classify condensers based on performance, they fall into four groups below.
In water-cooled condensers, water acts as the primary cooling medium. Water absorbs the heat of the hot refrigerant, reduces its temperature, and eventually causes condensation.
Due to high efficiency, precise refrigerant temperature control, and significant cooling capacity, these condensers are widely used in power plants, chemical and petrochemical industries, food and pharmaceutical industries, and large HVAC systems.
Other advantages of water-cooled condensers include the ability to use chilled water to increase system efficiency and the possibility of using cooling tower water.
In air-cooled condensers, air acts as the cooling medium. Air passing over condenser coils absorbs the heat of the refrigerant and condenses it.
These condensers are widely used in residential and commercial HVAC systems, small and medium chillers, and some industrial systems due to their simple structure, low maintenance cost, and lack of need for water sources.
Air-cooled condensers are usually installed outdoors, and their efficiency may decrease in hot seasons due to dependence on ambient air temperature.
Evaporative condensers combine the features of water and air condensers. In this type, part of the water sprayed onto the coils evaporates and absorbs latent heat from the environment. This lowers the temperature of the remaining water, increasing condenser efficiency.
Evaporative condensers are highly valued in hot and dry regions due to lower energy consumption compared to water condensers. They are commonly used in large HVAC systems, industrial chillers, and in food and pharmaceutical industries.
The shell and tube condenser is a type of heat exchanger used for condensing vapor into liquid in many industrial processes, including refrigeration systems.
In this type of condenser, thin tubes are placed inside a cylindrical shell. The vapor flows through the tubes, while the cooling fluid (water or air) circulates around the tubes inside the shell. Through heat transfer between these two fluids, the vapor condenses into liquid inside the tubes.
These condensers are among the most commonly used types in various industries due to their simple design, high reliability, and flexibility in construction.
Condenser Type | Advantages | Disadvantages | Applications | Approximate Cost |
|---|---|---|---|---|
Air-cooled | Easy installation, low maintenance cost, no need for water source | Low efficiency in hot weather, sensitive to pollution, high noise level | Residential and commercial HVAC, small and medium chillers | Low |
Water-cooled | High efficiency, precise refrigerant temperature control | Requires water source, higher maintenance cost, risk of scaling | Various industries (power plants, petrochemicals, food), large HVAC systems, large chillers | Medium |
Evaporative | Low energy consumption, suitable for hot and dry regions, higher efficiency than air-cooled | Requires water, risk of scaling, complex structure | Large HVAC systems, industrial chillers | Medium to High |
Shell and Tube | Simple structure and easy maintenance, high pressure tolerance, high thermal efficiency | Risk of scaling, high pressure drop, sensitivity to vibration, larger size compared to some other types | Oil and gas industries, power plants, chemical industries, food industries, HVAC systems | Medium to High |
We can also classify condensers based on their application. For example, cold storage condensers, chiller condensers, duct split condensers, and industrial condensers.
Cold storage condensers are one of the vital components of cold storage refrigeration systems. Their main function is to discharge the heat absorbed by the refrigerant in the evaporator and cool the refrigerant to maintain low temperatures inside the cold storage.
Cold storage condensers are usually either air-cooled or water-cooled, and the appropriate type depends on factors such as storage capacity, ambient temperature, and spatial limitations. They must be designed to operate continuously and efficiently to maintain the desired temperature inside the cold storage.
Chillers are devices used to produce chilled water and are widely used in central and industrial HVAC systems. The chiller condenser is responsible for discharging the heat absorbed from the chilled water.
This heat is usually transferred to the outside environment. Chiller condensers can be water-cooled, air-cooled, or evaporative, and the appropriate type depends on factors such as chiller capacity, ambient temperature, and water availability.
Split condensers are heat exchangers located in the outdoor unit of duct split systems. Their main function is to convert refrigerant vapor (gas) into liquid by transferring heat from the hot refrigerant to the surrounding environment.
In this condenser, the hot refrigerant vapor from the compressor comes into contact with the condenser tubes, loses heat to the environment, and condenses into liquid. After liquefaction, refrigerant pressure decreases and it becomes ready to enter the evaporator. This process, as part of the refrigeration cycle in HVAC systems, is repeated continuously.
By choosing a high-quality and well-designed duct split condenser, you can achieve high energy efficiency. However, these condensers usually require more installation space due to their larger dimensions.
Industrial condensers are used in a wide range of industries, including petrochemicals, food, pharmaceuticals, and chemical industries. They are employed for cooling process fluids, condensing vapors, and recovering chemicals.
They come in diverse sizes, capacities, and designs, and the appropriate choice depends on the specific requirements of each process.
Condenser Type | Advantages | Disadvantages | Applications | Approximate Cost |
|---|---|---|---|---|
Chiller | High efficiency, precise temperature control, suitable for central HVAC systems | Complex structure | Large buildings, commercial centers, industries | High |
Industrial | Custom design, high capacity, suitable for heavy-duty conditions | High construction cost, requires specialized maintenance | Heavy industries, refineries, power plants | Very High |
Cold Storage | Designed for low temperatures, corrosion resistance, high reliability | High maintenance cost | Industrial cold storages, food cold storages | Medium to High |
Duct Split | High efficiency, long lifespan, diverse models, quiet operation | Requires more space | Residential buildings, commercial areas, offices and organizations | Medium to High |
One of the most important classifications of condensers is based on their body material, which are generally divided into two categories: steel condensers and copper condensers.
Steel condensers are widely used in many industries due to their high resistance to corrosion, long lifespan, and hygienic properties. These condensers are usually made of stainless steel, which is resistant to rust and easy to maintain.
.
Copper condensers are among the most popular options in refrigeration and air conditioning systems due to their high heat transfer coefficient and soldering capability. These condensers are widely used in both residential and industrial equipment.
Feature | Steel Condenser | Copper Condenser |
|---|---|---|
Corrosion resistance | Very High | Medium |
Heat transfer | Medium | High |
Weight | Heavy | Light |
Price | More Expensive | Cheaper |
Condensers can also be classified based on the refrigerant used, into two categories: ammonia condensers and Freon condensers. Below we introduce both types.
This type of condenser uses ammonia as a refrigerant. Ammonia is a natural, efficient refrigerant with high heat transfer capacity. Due to their high cooling capacity, ammonia condensers are commonly used in large industrial refrigeration systems such as ice factories and food industries.
Advantages of ammonia include low cost, no ozone depletion, and low global warming potential. However, ammonia is toxic and flammable, requiring special safety equipment.
This type of condenser uses Freon gases (chlorofluorocarbons or CFCs and hydrochlorofluorocarbons or HCFCs) as refrigerants.
In the past, Freon gases were very popular due to their good thermodynamic properties and non-flammability. However, because of their harmful effects on the ozone layer, the production and use of many Freon gases have been banned.
Today, alternative gases such as hydrofluorocarbons (HFCs) are used in Freon condensers. Freon condensers are widely used in residential and small to medium commercial refrigeration systems due to their high efficiency and variety of capacities.
Condenser Type | Advantages | Disadvantages | Applications | Approximate Cost |
|---|---|---|---|---|
Ammonia | High cooling capacity, low refrigerant cost, environmentally friendly, high efficiency | Toxicity of ammonia, need for special safety equipment, unpleasant odor, risk of leakage | Large industries such as ice factories, food industries, industrial refrigeration systems | Low initial cost, medium maintenance cost |
Freon | Model variety, high efficiency at low temperatures, high safety, suitable for small systems | Damage to the ozone layer (some types of Freon), high cost of some Freon types, high global warming potential (some types of Freon) | Household and commercial refrigeration systems, HVAC systems, pharmaceutical industries | Higher initial cost, lower maintenance cost |
The price of a condenser depends on various factors, such as the type of condenser (water-cooled, air-cooled, evaporative, etc.), the materials used in its construction (copper, aluminum, etc.), cooling capacity, manufacturer brand, dimensions, and design complexity.
In general, industrial condensers usually have a higher price compared to residential condensers due to their larger capacity and more complex design. In addition, market fluctuations and raw material costs also affect condenser prices.

Condenser design is a complex and precise process that requires consideration of multiple factors. The main goal of designing a condenser is to create an efficient device that can effectively transfer the heat absorbed by the refrigerant to the surrounding environment, thereby ensuring the proper performance of the cooling system.
Important factors to consider in condenser design include: type of cooling medium (water, air, or a combination), fluid flow rate, inlet and outlet fluid temperature, working pressure, material composition, dimensions and geometry, and environmental conditions. Key parameters such as overall heat transfer coefficient, pressure drop, and contact surface area must also be carefully calculated.
Manufacturing a condenser is a detailed multi-stage process requiring technical knowledge, proper equipment, and adherence to quality standards. Below are the main steps:
The first stage is precise design and engineering. Based on system requirements, cooling medium type, system capacity, environmental conditions, and space limitations, technical specifications of the condenser are determined. Parameters such as dimensions, number of tubes, fin type, material composition, wall thickness, and joints are defined. Numerical simulation software is also used for optimization.
After finalizing the design, raw materials are prepared. These include copper or aluminum tubes, aluminum fins, joints, insulation materials, and soldering or welding materials. The quality of raw materials directly affects performance and lifespan.
The condenser core is the heart of the unit and transfers heat between the refrigerant and cooling medium. Tubes are placed in order on fin plates and joined by soldering or welding. The type of connection and soldering/welding material depends on the tube and fin materials.
After building the core, a housing is constructed around it. Housing can be made of metal, plastic, or composite depending on type and environmental conditions. It protects the core and directs the cooling medium flow.
Inlet and outlet fittings for refrigerant and cooling medium are installed. These fittings are usually copper or steel and joined by welding or soldering.
The condenser is externally insulated to reduce heat loss and improve efficiency. Common insulation materials include rock wool, polyurethane foam, or polystyrene.
The finished condenser undergoes tests such as leak testing, pressure testing, flow rate testing, and thermal testing. Any defects are corrected before final approval.
In some cases, the condenser is coated with protective layers like epoxy paint or galvanization to increase corrosion resistance and lifespan.
After successful testing, the condenser is packaged for shipping. Proper packaging prevents damage during transport.
Finally, the condenser is installed in the cooling system and connected to other components. After adjustments, the system is started and condenser performance is evaluated.
