small self contained air conditioning

portable systems window units through the wall units packaged terminal units

This type of refrigeration includes small hermetically sealed air conditioning units used.

- Portable system unit: Portable air conditioning is a compact air conditioning unit that can be installed low on a wall, sitting just above the floor. These systems are mostly installed in cafeterias, shops, large reception rooms, hotel foyers, or server rooms. This system is perfect for companies who do not want an air conditioning system on their walls and ceilings.

- Window unit or Through the wall unit: Traditionally mounted on a window ledge supported with a bracket or more common these says thrugh a cut out in the wall. This type of refrigeration unit has a double shaft fan motor with fans mounted on both sides of the motor. One at the evaporator side and the other at the condenser side.

- A packaged terminal air conditioner: Many are designed to go through a wall, having vents and heat sinks both inside and outside.

small split air conditioning

single split air conditioning less 12kW

Single split AC systems are the most common. "Split air conditioning" means that the system consists of two parts: an indoor unit - the heat exchanger - and an outdoor unit - the compressor. The two units are interconnected by field-assembled refrigerant piping.

large split air conditioning and other types of air to air systems

large single split and multi split air conditioning

- Large single splits are a larger version of a small split, consisting of a single indoor unit and an outdoor unit.

- Multi-split systems can have multiple indoor units (up to 8) connected to a single outdoor unit. Most recent models are designed to be reversible (i.e. cooling in hot weather and heating in cold weather).

R-407C

R-410A

variable refrigerant flow systems

Sophisticated multi-split systems where multiple outdoor units can support many indoor units (up to 64). Some of these systems are designed to be able to simultaneously heat and cool different parts of the same building (each indoor unit can be individually selected to heat or cool).

12 - 150

R-410A

ducted and packaged rooftop systems

Provide cooling through a ducted air ventilation system. A direct expansion evaporator is located in an air handling unit to cool the air which is ducted around the building to be cooled.

12 - 200

R-410A

chiller systems

small and medium size chillers

Chilled water is pumped to air handling units or terminal units which provide conditioned air. Small and medium sized chillers often use small scroll, reciprocating or screw compressors.

50 - 750

R-407C

R-410A

large chillers

Large chillers typically use a flooded evaporator, water-cooled condenser, and large screw or centrifugal compressor.

750 - 1000

HFC-134a

industrial refrigeration

small or medium sized systems

Systems that are usually dedicated to a particular cooling demand to store specific products. They are often located close to the cooling demand.

20 - 100

R-404A

HFC-134a

large distributed systems

These systems can be composed of different sections. They are used to cool large loads in processes such as blast freezers, process heat exchangers and cold storage facilities. A primary refrigerant is routed from a central machine room (containing large refrigeration compressors) to a number of evaporators serving one or more cooling demands. The primary refrigerant often circulates over significant distances (hundreds of meters).

100 - 5000

R-404A

R-507A

large chiller systems

These systems can be used to satisfy different cooling demands. A primary refrigerant is used in a chiller to cool a secondary heat transfer fluid that circulates to a number of separate cooling demands.

200 - 5000

commercial refrigeration

stand alone factory sealed equipment

Small systems that can be compared to household refrigerators, but are used for commercial purposes (for example, beverage-only refrigerators with transparent windows for displaying products, water coolers or ice machines ).

0.1 - 1

HFC-134a

condensing units

A condensing unit typically is a high side assembly of a refrigeration system. It is an assembly of compressor, condenser, fan motor, controls and a mounting plate.

It has the function of a heat exchanger to cool down and condense the incoming refrigerant vapor into liquid and a fan for blowing outside air through the heat exchanger section to cool the refrigerant inside.

Systems connected to a remotely located compressor and condenser, with a cooling evaporator in the refrigerated space (eg, retail display).

HFC-134a

centralised system

These central systems are the most common type of air cooling systems as they are quick and efficient at cooling down larger areas. Large distributed systems with a number of cooling evaporators connected to a remotely located compressor bank and an external condenser.

The system works from a cooling compressor, which is located outside. Much like other air conditioners, a coil filled with refrigerant is used to cool the air, which is then blown out by a fan and circulated throughout the building with the use of ducts located on the walls or floors. If there is warm air in a room, the ducts will register the heat and the air will then be transported back to the air conditioner to be pushed outside.

transport refrigeration

road vehicles

Small on-road vehicles (vans, trucks, trailers) usually have a refrigeration compressor located in the main engine compartment. Larger road vehicles are usually equipped with a factory-mounted pre-charged refrigeration unit in the front of a refrigerated trailer. These units are fitted with a small diesel engine and a factory built refrigeration circuit - installation work does not involve any refrigerant piping.

HFC-134a

intermodal containers

These types of containers (reefer containers) can be found on road vehicles or on ships. The intermodal containers have electrically driven compressors. When a container is on board of a ship it is connected to the ship's electricity supply. When a container is used by a road vehicle, it is connected to the main diesel engine generator or uses a dedicated diesel generator.

ships

Ships require a range of different cooling systems depending on their function (including refrigerated cargo vessels, fishing vessels and passenger liners). Ship refrigeration systems are significantly larger than those for road vehicles.

40 - 2000

mobile air conditioning

cars and small vans

The compressor and condenser are separately located in the engine compartment of the vehicle and evaporator usually located in a ventilation duct between the engine compartment and the passenger cabin.

larger vehicles

Often located in a single unit containing all system components. On some bus and coach systems the compressor is located adjacent to the main vehicle engine and driven via a belt connection.
