- Typical capacity
- Refrigeration units for cold rooms typically range from 1.5 kW to 15 kW, depending on the volume and insulation of the space.
- Power supply
- Commonly found units operate on 230V single-phase or 400V three-phase power, with specific requirements varying by unit size and manufacturer.
- Refrigerant type
- Modern units typically utilise HFC refrigerants such as R404A or R449A, with a growing trend towards lower GWP alternatives like R290 or R744.
- Temperature range
- For this class of equipment, typical operating temperatures can range from +10°C down to -25°C, suitable for chillers or freezers respectively.
- Installation type
- Units are commonly split systems, with an indoor evaporator and an outdoor condenser, or monoblock units for smaller cold rooms.
- Control system
- Typically includes a digital thermostat with temperature display and basic control functions for defrost cycles and fan operation.
