What is an Outdoor Condenser Unit

A Condenser is typically a device of coil or heat exchanger attached to a series of pipes where high-pressure refrigerant is introduced.

Its main job is to facilitate the transfer of heat from the refrigerant and convert it into a liquid state.

In this operation, it can release the heat absorbed from the indoor space, contributing to the cooling cycle.

So mainly, it transforms the refrigerant substance of the air conditioning or refrigeration, from its gaseous state into a liquid state by cooling.

To say it simply, a condenser unit is used to discharge unwanted heat from the refrigerant.

After the release of the heat, the condenser unit prepares for the next step of the cooling operation.

Where Outdoor Condenser Units Are Used?

Where Outdoor Condenser Units Are Used

There are various needs for outdoor condenser units in the market based on the size, and other technical specifications like evaporating temperature.

To meet these different needs, there are plenty numbers of suitable outdoor condenser units available in the market for low, medium, and high temperatures from small households to large industrial applications.

The wide range of outdoor condenser unit applications starts from air conditioning systems, and commercial refrigerators to temperature-controlled food preparation areas.

The outdoor condenser unit is also used in the power generation sector including biomass, gas-fired, water incineration/ waste incineration plants, oil-fired power plants, etc.

Some of the most common outdoor condenser unit applications are:

  1. Household Air Conditioner
  2. Steam Power Plants
  3. Small Cold Storage
  4. Cold Room, Display Counters, Refrigerated Display Cabinets
  5. Mobile Cold Storage
  6. Dual Temperature Cold Storage
  7. Heat Exchange System
  8. Drinking Fountains

Why Condenser Units Should Be Placed Outside?

Why Condenser Units Should Be Placed Outside?

Placing your condenser unit outside a flat surface helps the inside motor doesn’t get displaced while vibrating, runs the motor at high speed, moves compressor oil smoothly, and flows refrigerant better.

It also helps your condenser from excess stress and huge noise problem.

Additionally, based on the functionality of your condenser unit, it should always be placed in outside.

Because when the ac is in cooling mode, the indoor unit absorbs all the heat from your room and releases heat in an open space.

So outdoor condenser unit needs an adequate air supply to cool the refrigerant and enough airflow to function properly.

But when the ac is in heating mode, theoretically the condenser unit is your indoor unit, because now it consumes the heat of the compressor and makes your indoor room warm.

What Is the Difference Between Condenser and Condensing Unit?

What is the Difference Between Condenser and Condensing Unit

Most of the time you will find that these two terms are used interchangeably, but there are some differences between condenser units and condensing units.

The primary function of the condenser is to convert the heat from the refrigerant that releases thermal energy and converts from a high-pressure vapor state to a liquid state.

On the other hand, a condensing unit is a comprehensive assembly that includes not only the condenser coil but also other essential components like a compressor, the fan, an electrical control circuit, connecting pipe, and possibly extra elements like a reversing valve.

While the condenser unit focuses solely on the heat exchange and refrigerant condensation process, the condensing unit manages various aspects of the high-pressure side of the refrigeration cycle.

It includes heat removal, refrigerant condensation, and managing the efficient operation of overall system performance.

What Are the Accessories of Outdoor Condensing Units?

What are the Accessories of Outdoor Condensing Units

There are various types of accessories and components based on functionality, protection, and efficiency in an outdoor condensing unit.

Such as liquid receivers, filter driers, oil separators, axial fans, pressure gauges, weatherproof covers, condenser coil guards, vibration isolators, coil cleaners, etc.

But the main accessories based on the functionality are its condenser coil, evaporator, expansion valve, and most importantly the compressor.

Based on the different use applications and needs, outdoor condensing units may use different types of compressors such as scroll, rotary, semi-hermetic, or reciprocating piston compressors.

There are different brand compressors in each of these different types for example Copeland, Danfoss, Panasonic, Daikin, Hitachi, Bitzer, Embraco etc.

What Difference between Outdoor Air Conditioner Unit and a Commercial Outdoor Condensing Unit?

An outdoor air conditioner unit and a commercial outdoor condensing unit are different for different application scenarios.

An outdoor air conditioner unit is used for home air conditioning, and split air conditioning.

They are characterized by low power, low noise, low energy consumption, and generally use frequency conversion compressors.

The commercial outdoor condensing unit is used in the commercial field, such as small cold storage, walk-in refrigerator, and mobile cold storage.

It is characterized by large size, low evaporating temperature, and low to medium temperature range operation.

Corresponding to commercial outdoor condensing units is the commercial indoor condensing unit, which is used in display cabinets, kitchen refrigerators, and so on.

You can see more pictures and information on commercial outdoor condensing units and indoor condensing units here.

Which Is the Best Location for an Outdoor Air Conditioner Unit and Outdoor Condensing Unit?

Which Is the Best Location for an Outdoor Air Conditioner Unit and Outdoor Condensing Unit

There are some important factors to consider before placing your outdoor condensing unit in a perfect location that can significantly affect its efficiency, maintenance, and durability.

As a heat extractor of your indoor unit, an outdoor condensing unit can do its job better when there is no extra heat, direct sunlight, or other heat sources near it.

Try to place it north or east side of your house so it gets a natural shade from the sun.

Make sure there is a minimum of 2 to 3 feet enough space surrounding the unit’s maximum airflow and should not be near or behind the doors.

Place it on a hard, strong, and level surface like concrete or PVC-made slabs.

The outdoor condensing unit does make some noise so consider the location of your bedroom and also the comfort zone of your neighbors.

It’s best practice to place an outdoor condensing unit in a place where it is accessible for regular maintenance and there are no heavy debris-producing trees or a dusty area that makes the outdoor unit’s filter dirty or blocked.

What Is the Difference Between an Outdoor Condensing Unit and an Indoor Condensing Unit?

What Is the Difference Between an Outdoor Condensing Unit and an Indoor Condensing Unit

An indoor condensing unit is part of the air conditioning system that is attached to the wall inside the room, mainly absorbing the hot air in the room and blowing cold air or warming the room by circulating hot air.

While the outdoor condensing unit is attached to the outside wall or on the ground and the primary function is to extract or emit heat from the ambient air.

In a split system, the outdoor condensing unit is separated from the indoor condensing unit but they work together.

The indoor air condensing unit is consisting of an evaporator coil, filters, and ducts to allow air to travel through the room while the outdoor condensing unit has a compressor, condenser coil, expansion valve, fan, refrigerant, etc.
