Unité de condensation pour réfrigérateur et congélateur commerciaux

Domi Refrigeration fournit ce compact condensing unit for commercial refrigerators and freezers for OEM buyers who require a refrigeration assembly matched to specific cabinet dimensions, operating conditions, refrigerant requirements, and cooling loads.

The condensing unit integrates key refrigeration components into a compact assembly and can be used with compatible evaporators in commercial refrigeration equipment. Typical applications include display refrigerators, beverage coolers, reach-in refrigerators, commercial freezers, and other refrigerated cabinets.

A condensing unit should not be selected from compressor horsepower, outside dimensions, or refrigerant alone. Cooling capacity, evaporating and condensing conditions, refrigerant, compressor operating envelope, condenser airflow, electrical supply, installation space, and system controls should be reviewed before production or replacement.

Portée du produit et rôle dans le système

A condensing unit forms the high-pressure side of a vapor-compression refrigeration system. Depending on the project configuration, the assembly typically combines a compressor, condenser, fan motor, piping, and mounting base, with additional refrigeration or electrical components specified according to the equipment design.

The unit works together with the evaporator, expansion device, refrigerant piping, controls, and cabinet airflow system. Final system performance therefore depends on the complete refrigeration design rather than the condensing unit alone.

Typical applications include:

• Commercial refrigerators
• Commercial freezers
• Display refrigerators
• Beverage coolers
• Reach-in refrigerators and freezers
• Upright refrigerated cabinets
• Undercounter refrigeration equipment
• Food and beverage display cabinets
• Other customized refrigeration equipment

Domi can review OEM projects based on customer drawings, samples, equipment specifications, and required operating conditions.

Référence de construction typique

The configuration below is a general reference for project discussion. Actual components and specifications depend on the approved design.

Component brands, materials, electrical devices, refrigerant accessories, and connection arrangements should be confirmed during the RFQ and drawing-approval stages.

Compact design for refrigeration cabinets

Commercial refrigerators and freezers often have limited space for the refrigeration system. The condensing unit therefore needs to be matched closely with the cabinet structure, ventilation path, and service area.

Important mechanical and airflow considerations include:

• Overall width, height, and depth
• Compressor position
• Condenser face area
• Fan size and airflow direction
• Air inlet and outlet clearance
• Suction and liquid line positions
• Electrical connection location
• Mounting-hole pattern
• Vibration isolation
• Service accessibility
• Clearance from cabinet panels and other components

A compact outside dimension alone does not determine whether a condensing unit is suitable for a particular refrigerator or freezer.

How to select a refrigerator or freezer condensing unit

For a new OEM refrigeration project, provide the following information for engineering review:

1. Equipment application: refrigerator, freezer, display cabinet, beverage cooler, reach-in cabinet, or other refrigeration equipment.
2. Cooling requirement: required refrigeration capacity, cabinet volume, product load, and expected operating range.
3. Conditions de fonctionnement : cabinet temperature, evaporating temperature, condensing temperature, ambient temperature, and expected maximum operating condition.
4. Fluide frigorigène : refrigerant designation and any project-specific refrigerant requirements.
5. Compressor requirements: preferred compressor model or brand, capacity, displacement, voltage, frequency, and operating envelope where specified.
6. Condenser and airflow: required heat-rejection duty, fan configuration, airflow direction, ventilation openings, and available air-side clearance.
7. Installation envelope: maximum width, height, depth, mounting-hole locations, piping exits, and service space.
8. Electrical requirements: voltage, frequency, phase, starting components, protection devices, and control interface.
9. Quality requirements: leakage testing, electrical inspection, dimensional inspection, labeling, traceability, and packaging requirements.
10. Commercial information: sample quantity, estimated annual volume, SKU mix, destination market, and requested delivery schedule.

Compressor and refrigerant matching

The compressor is a key component of the condensing unit, but compressor selection should be based on the actual refrigeration operating conditions rather than nominal horsepower alone.

The following should be reviewed together:

• Fluide frigorigène
• Capacité de refroidissement requise
• Température d'évaporation
• Température de condensation
• Suction condition
• Température ambiante
• Tension et fréquence
• Enveloppe de fonctionnement du compresseur
• Expected load range
• Starting and protection requirements

If the buyer specifies a compressor model, Domi can review the surrounding condenser, fan, piping, base, and accessory configuration according to the project requirements.

Condenser and airflow review

The condenser must reject the heat generated by the refrigeration system under the specified operating conditions. Condenser size, fan airflow, ventilation openings, and installation clearance therefore need to be considered together.

Restricted airflow, hot-air recirculation, insufficient ventilation clearance, or unsuitable fan selection can affect condensing conditions and system performance.

For cabinet-integrated condensing units, provide the cabinet ventilation arrangement or installation drawing whenever possible.

Développement d’unités de condensation OEM et personnalisées

For refrigerator and freezer manufacturers, the condensing unit often needs to fit a specific cabinet platform rather than a universal installation space.

Domi prend en charge Projets d’unités de condensation OEM et ODM based on:

• Plans du client
• Existing samples
• Required refrigeration capacity
• Dimensions du coffret
• Fluide frigorigène
• Exigences pour le compresseur
• Condenser configuration
• Fan and airflow requirements
• Spécifications électriques
• Raccordements du réfrigérant
• Mounting interfaces
• Quantité de production cible

Before mass production, the component list, drawing revision, key dimensions, electrical specification, piping arrangement, inspection requirements, and sample approval criteria should be confirmed.

Revue de fabrication et de qualité

Depending on the configuration, the manufacturing and assembly process may include condenser production, tube forming, brazing, compressor installation, fan assembly, refrigeration piping assembly, electrical component installation, leakage testing, inspection, and packing.

For project-specific orders, the buyer and Domi should confirm the required:

• Component specifications

Vérifications de remplacement et de compatibilité

A replacement condensing unit is not automatically interchangeable because two units use compressors with similar capacities or have similar outside dimensions.

Differences in refrigerant, compressor operating envelope, condenser capacity, fan airflow, electrical specification, piping connections, mounting locations, and control components can affect compatibility.

Pour les projets de remplacement, comparez :

• Fluide frigorigène
• Capacité de refroidissement
• Compressor specification
• Conditions d’évaporation et de condensation
• Tension et fréquence
• Condenser configuration
• Débit d’air du ventilateur
