Refrigeration Equipment
Refrigeration Compressors for Complete Cooling Systems
The refrigeration compressor is a key component of the cooling cycle and circulates refrigerant through the system. Uniref coordinates compressor selection with the evaporator, condensing unit, refrigerant piping and controls according to the required room duty.
In view
Compression function
The compressor receives low pressure refrigerant vapour and raises its pressure and temperature.
Where it is used. It is used in refrigeration systems serving cold rooms, freezer rooms, chillers, blast systems and cold storage.
Compressor Selection
How a Refrigeration Compressor Is Selected
A refrigeration compressor should be selected from the calculated refrigeration duty rather than from room dimensions alone. Product load, required temperature, incoming product temperature, ambient conditions and operating pattern all influence the compressor requirement.
Selected input
Product being stored
The product type affects the heat load and helps establish the refrigeration duty that the compressor must handle.
Selection result
Condenser selection
The condenser is selected to reject the heat produced by the refrigeration cycle under the expected ambient conditions.
Affected by this input
Evaporator selection
The evaporator is selected according to the room temperature, cooling duty and required air circulation.
Selection result
Controller configuration
The controller configuration is established according to the required temperature, sensors and compressor operating sequence.
Compressor Applications
Refrigeration Compressors for Different Cold Storage Applications
Different refrigeration applications place different demands on the compressor. Uniref selects compressor equipment according to the room temperature, product load, cooling requirement and expected operating conditions.
Walk in cold room
A compressor for a walk in cold room is selected according to the required room temperature, product load and room dimensions.
The refrigeration duty determines the compressor capacity and its connection with the rest of the system.
Explore cold room
Chiller room
A chiller room requires compressor selection based on the required chilled condition and the heat load entering the room.
The compressor configuration changes according to the calculated cooling duty and operating temperature.
Explore cold room
Freezer room
A freezer room requires a compressor suitable for the lower operating temperature and expected product loading.
The compressor selection is based on the required refrigeration duty and the complete system operating conditions.
Explore cold room
Blast freezer
A blast freezer places a high cooling demand on the refrigeration system because products need rapid temperature reduction.
Compressor selection considers incoming product temperature, daily loading and the required freezing condition.
Explore cold room
Blast chiller
A blast chiller requires refrigeration equipment selected around rapid product cooling and the expected product load.
The compressor duty is determined from the required cooling conditions and operating pattern.
Explore cold room
Modular cold room
A modular cold room requires compressor selection based on its room dimensions, insulation arrangement, product requirement and operating temperature.
The compressor capacity changes according to the calculated refrigeration duty.
Explore cold room
Large cold storage
Large cold storage requires compressor selection based on storage capacity, product loading, room dimensions and operating hours.
The compressor arrangement is determined from the total refrigeration duty and required operating conditions.

Refrigeration Compressor Selection for Indian Conditions
Indian operating conditions should be included when assessing refrigeration compressor requirements for a cold storage application. Ambient temperature, dust, loading patterns, operating hours and power conditions are design inputs rather than performance claims.
- High summer temperatures
- High outdoor temperatures affect condensing conditions and should be considered when selecting the compressor and connected refrigeration equipment.
- Industrial dust
- Dust around the equipment installation can affect condenser and fan operation, so the site environment should be considered during system planning.
- Long operating hours
- Long operating periods affect the expected compressor duty and should be considered when selecting the equipment configuration.
- High product loading
- High product loading increases the cooling demand and can require a compressor selected for a higher refrigeration duty.
- Frequent door openings
- Frequent door openings increase warm air entry and can add to the refrigeration load handled by the compressor.
- Power fluctuation considerations
- Power conditions should be considered when planning compressor operation, controls and the wider refrigeration system.
- Seasonal ambient changes
- Seasonal changes in outdoor temperature can affect system operating conditions and should be included in the equipment assessment.
Complete Refrigeration System
How a Refrigeration Compressor Works Within a Complete System
A refrigeration compressor works together with the evaporator, condensing unit, refrigerant piping and controls to complete the cooling cycle. Correct coordination between these components is important when designing or upgrading a refrigeration system.

Refrigerated room
The room application establishes the required temperature, storage conditions and refrigeration duty.
Compressor Replacement and Upgrades
Upgrade an Existing Refrigeration Compressor System
An existing refrigeration system may require compressor replacement or related equipment changes when its current configuration no longer matches the required cooling duty. An equipment assessment helps determine whether replacement, capacity enhancement, control modernization or a broader retrofit is suitable.

Refrigeration Compressor FAQs
The compressor is selected according to the room temperature, product being stored, room dimensions, storage capacity and refrigeration duty. Daily loading, door openings, ambient conditions and operating hours are also considered.
Compressor capacity is determined from the calculated refrigeration duty and required operating conditions. Room size is only one input and cannot by itself determine the required compressor capacity.
A freezer room requires a compressor selected for its lower operating temperature and calculated refrigeration duty. Product loading, incoming product temperature, room dimensions and operating hours also influence the selection.
Yes, an existing compressor can be assessed for replacement when its condition or capacity no longer matches the current refrigeration requirement. The replacement should be selected after reviewing the complete refrigeration system.
A compressor raises refrigerant pressure and circulates refrigerant through the system. A condensing unit is a larger assembly that can include the compressor and other components required on the heat rejection side of the refrigeration system.
Yes, Uniref supports compressor installation and commissioning as part of a complete refrigeration system. The compressor is selected according to the room application and calculated refrigeration duty.
Indian ambient temperature is considered because it affects the condensing side of the refrigeration system and the operating conditions of the compressor. Other site factors such as dust, operating hours and seasonal changes can also be included in the assessment.
Uniref provides maintenance and AMC support for refrigeration equipment along with installation, commissioning and upgrade services. The applicable service depends on the compressor, refrigeration system and operating requirements.
