Overview

U-Type Condenser Design for Refrigeration Heat Rejection

A U-type air-cooled condenser rejects heat from refrigerant by transferring it through a finned coil to ambient air. Fan-driven airflow supports the condensation process when the unit operates within its specified design conditions. The published LFNU model range includes different heat-exchange areas, fan configurations, airflow figures, motor power ratings and connection sizes. To select a suitable condenser, buyers should consider the refrigerant, required heat rejection, condensing conditions, ambient temperature, electrical supply and available installation space.

  • U-Type Heat-Exchange Layout

    The product drawing shows a U-type coil arrangement within a framed condenser structure. This configuration groups the heat-transfer coil and fan assembly into one equipment package. Confirm the final footprint and access requirements using the selected model drawing.

  • Fan Configuration and Airflow

    The source table lists fan blade designations such as 4D400, 4D450, 4D500, 4D550, 4D600 and 4D630. Airflow figures vary by model and should be interpreted alongside the fan quantity and rating conditions listed in the confirmed datasheet.

  • Range of Heat-Exchange Areas

    The published heat-exchange area spans from 26 m² to 210 m². Coil area is one factor in heat transfer; refrigerant type, condensing temperature, ambient conditions, airflow and coil construction also affect actual performance.

  • Motor and Electrical Requirements

    The original table includes horsepower ratings and fan power information. Confirm the exact motor power, voltage, frequency, phase, current and control method from the selected model’s nameplate and wiring diagram before procurement.

  • Refrigerant Pipe Connections

    The source table lists inlet and outlet pipe diameters for each model. Confirm the diameter convention and connection type with the manufacturer, and check compatibility with the system piping design.

  • Installation and Routine Maintenance

    Provide a stable supporting base, unobstructed airflow and safe access for coil cleaning and fan servicing. Follow the manufacturer’s installation instructions and electrical safety requirements.

FAQ

Frequently Asked Questions

  • What is a U-type air-cooled condenser?

    It is a refrigeration heat-rejection unit that uses a finned coil and fan-driven ambient airflow to transfer heat from refrigerant to the surrounding air.

  • What range of motor ratings is shown?

    The source table lists model ratings from 3 HP to 40 HP. Confirm whether the rating refers to the associated refrigeration unit or another specified motor rating before comparing models.

  • What heat-exchange area options are available?

    The visible table lists heat-exchange areas from 26 m² to 210 m². The final model should be selected based on the system load and verified operating conditions.

  • What should be checked before selecting a model?

    Confirm refrigerant type, required heat rejection, condensing and ambient temperatures, electrical supply, pipe connections, installation dimensions and maintenance clearances.

  • Are airflow and power values the same for every model?

    No. The source table shows different fan configurations, airflow values and power entries. Use the confirmed model datasheet to verify these values for the selected configuration.
