How split refrigeration units work in cold rooms
Separate condensing units and evaporators: layout, installation considerations and selection for chilled or frozen storage.
Editorial review: · AACORE SUPPLY
Two assemblies connected by refrigerant piping
A split system places the evaporator inside the cold room and the condensing unit in a separate location. Refrigerant piping connects the two assemblies according to the manufacturer’s requirements. This separates the position of the heat rejection from the refrigerated enclosure.
A cold room split is not a comfort air conditioner. Its selection must match the required storage temperature, heat load and intended application.
When a separate location helps
Consider a split when heat needs to be rejected away from the room or when the proposed monoblock location cannot provide suitable ventilation. The evaporator position can also be considered separately from the outdoor assembly.
This flexibility has limits. Pipe lengths, height differences, ambient conditions and installation accessories must fall within the limits of the exact reference.
Prepare the installation
Check voltage, frequency, drainage, maintenance access and internal air distribution. Stored products should not block the evaporator’s airflow.
Connections and commissioning must follow the model documentation. Comparing units by room volume does not replace a heat load calculation or an installation design.
Choose the configuration that fits the site
A compact assembly may suit a room where its mounting and heat rejection requirements can be met. A split allows a separate layout to be considered. The choice depends on the site as well as its volume.
Filter by application and construction, compare the references, then open the selected product at HVAC Spare Parts to review its options and complete the order.
