VRF Outdoor Units

The power source of a VRF system

A VRF outdoor unit supplies the cooling and heating capacity required by the connected indoor units. Its inverter compressor responds to the active load and regulates refrigerant flow as room demand changes. This allows multiple zones to operate through one coordinated system while maintaining independent temperature control.

Modular capacity for larger buildings

Outdoor units may operate as a single module or as a combined modular group. Selection is not based only on the sum of indoor unit capacities. Simultaneous demand, permitted connection ratio, total pipe length, height difference and the combination limits published by the manufacturer must be reviewed together. Modular VRF systems are widely used in offices, hotels, residential developments, clinics, retail areas and mixed use buildings.

Installation conditions matter

The installation area must provide clear condenser airflow, service access and protection against recirculated discharge air. Electrical supply, protection devices, refrigerant pipe diameters, additional charge and oil return conditions are determined from the selected system documentation. Pressure testing, evacuation and commissioning must be completed with suitable equipment and recorded values.

Euroclima selects VRF outdoor units according to calculated building load and practical site conditions. This category contains high capacity and modular outdoor units intended for complete VRF projects.
