All About Condensing Units for Non-Experts

If you are the head of the purchasing department on an SME then it isn’t necessary to be an expert or to be an engineer to realize buying the right equipment. Even without expert technical knowledge, you can purchase the right refrigeration equipment and its units efficiently.

To understand what each piece of equipment does and things you need to look for while talking to the sellers regarding your project helps you in avoiding making the wrong choice. Therefore, if you are looking for condensing units, you must understand what a condensing unit actually does.

What is a condensing unit?

Condensing unit is one of the most essential equipment pieces of the refrigeration system as it rejects the entirety of the heat of the system that includes heat absorption by the evaporator as well as heat production by the energy entrance to the compressor.

The systems that involve heat transfer use condensing units are used to condense a substance from its gaseous state to its liquid state. Such appliances are the ones that transform refrigerant gas from its gaseous state to liquid state for continuing the refrigeration cycle. While doing so latent heat gets abandoned by the substance and transferred to the surrounding ambiance.

What is the economic impact of the condensing unit?

The condensing unit is the great saver of your refrigeration system by recycling refrigerant gas. It also prevents consuming and spending in this substance each time you need your products cooled.

What are the applications of condensing units?

Condensing units are created depending upon a number of designs and these come in a variety of sizes as per their application. For instance, condensing units used in a refrigerator eliminate the heat extracted from the unit and sends it outside.

Condensing units are used in air conditioners and in chemical procedures such as distillation, steam power stations, and several other heat exchanging systems. Commonly, the refrigeration water or surrounding air is used in many condensers.

What builds a condensing unit?

A condensing unit is usually used in HVACR systems i.e. heating, ventilation, air conditioning, and refrigeration systems are composed of:

  • A heat exchange sector for cooling and condensing vapor impending from the liquid refrigerant.
  • A compressor for elevating the pressure of the refrigerant and move it.
  • A ventilator for cooling the internal refrigerant by moving the outside air via the exchanger.

Where to locate a condensing unit?

Certain condensing units are located outside the building they are trying to cool off with the help of the tubes that go from the unit to the building.

What are the different types of condensing units?

There are three different types of condensing units –

  • Air-Cooled
  • Water-Cooled
  • Steam Cooled

We at Africhill specialize in manufacturing, supplying, and installing pack concealed condensing units that are aesthetically attractive as well as extremely practical. Our condensing units help in reducing operational noises to a great extent. To know more about our condensing units contact us today.

Air-Cooledcondensing Units – Considerationsduring Installation

Condensing units are temperature control devices that are used in refrigerators, air conditioners, heat pumps as well as chillers. These units help in moving energy in the heat form by compressing a gas called refrigerant vapor. Then it pumps the vapor through a system of coils and making use of the surrounding air around the coils to heat and cool spaces.

The condenser coils are located along with the compressor and controlling devices within the condensing units. Condensing units are available in a wide range of sizes from small ones used in office fountains to huge ones used in air condition buildings like the Pentagon. Also, these units vary in designs such as plain tube, plate type or parallel pass units and more.

At Africhill we manufacture and supply air-cooled condensing units of the highest standards.

What are Air-Cooled Condensing Units?

Air-cooled condensing units comprise a coil of ample surface so that air can be blown by a fan or induced by natural draft. Such units are usually used in small capacity refrigerating units such as residential air conditioners or air conditioning system of small offices. To keep these units working in the their best condition, these should be kept free from dust, dirt, lint and other foreign elements as accumulation of these particles may reduce the airflow around the tubes and fins.

Things to Consider while Installing Air-Cooled Condensing Units

Choosing the right location is the first and foremost thing that needs to be considered while installing an air-cooled condensing unit. At times customers have a plan for the location that might differ from the location the installing contractor may find suitable. Some customers want to utilize their indoor space completely and hence may wish for locating the condensing unit outdoors or in an indoor space that won’t interfere with their operation.

  • Indoor Considerations

If the preferred location is indoors the contractors must ensure that the location has sufficient ventilation. Also, air-cooled condensing units located indoors may add heat to the space which might be objectionable. So it is highly advised to check with the manufacturer for ventilation requirements before installing.

  • Outdoor Considerations

On the contrary, if the condensing unit needs to be installed outdoors, several components should be added to it. The added components include a crankcase heater to prevent refrigerant migration during the off-cycle when the unit is exposed to extreme cold temperatures. Another component is a fan-cycling control or a head-pressure controller that helps in keeping the high side pressure above a minimum value throughout low outdoor temperatures. Other components include air-sensing temperature controller, defrost timer, and an enclosure to protect the unit from outdoor environment.

We at Africhill are a well-established name as far as manufacturing, supply and installation of air-cooled condensing units. Our condensing units are visually appealing as well as highly functional.

Condensing Units – Classification and Usage!

Condensing units are temperature control devices that are used in refrigerators, air conditioners, heat pumps as well as chillers. These units help in moving energy in the heat form by compressing a gas called refrigerant vapor. Then it pumps the vapor through a system of coils and making use of the surrounding air around the coils to heat and cool spaces.

The condenser coils are located along with the compressor and controlling devices within the condensing units. Condensing units are available in a wide range of sizes from small ones used in office fountains to huge ones used in air condition buildings like the Pentagon. Also, these units vary in designs such as plain tube, plate type or parallel pass units and more.

Classification of Condensing Units

Condensing units can be classified as per their cooling method as well. The three main types include air-cooled, combined air and water cooled and water cooled condensing units.

  • Air-Cooled Condensing Units

Air cooled condensing units comprises a coil of ample surface so that air can be blown by a fan or induced by natural draft. Such units are usually used in small capacity refrigerating units such as residential air conditioners or air conditioning system of small offices. To keep these units working in the their best condition, these should be kept free from dust, dirt, lint and other foreign elements as accumulation of these particles may reduce the airflow around the tubes and fins.

  • Combined Air- and Water-cooled Condensing Units

Also, referred as evaporative condensing units, the combined ones consist of a coil that is cooled by spraying water from above and then allowing the cold air to enter from the bottom and blow across the coils. When the water evaporates from the coils a cooling effect is being induced that condenses the refrigerant within the coil. The hot refrigerant gas in the coil is then changed to the liquid state by combining the sprayed water and large column of moving air supplied by the fan. And the remaining water that does not get evaporated gets recirculated with the help of a pump.

  • Water-Cooled Condensing Units

Water cooled condensing units as names suggest are cooled using water alone. The water circulates through the tubes and coils within the unit enclosed in a shell. In these units the refrigerant moves through the annular space between the tubes or the coils. These condensing units are also termed as double pipe condenser based on its construction. These condensing units are eco-friendly options as well as eliminate the water disposal problems which further make it an economical means of cooling refrigerant gases.
