Each coil shall be leak and pressure tested to 450 psig, evacuated and pre-charged with a small holding charge of R-22.

Blower

Centrifugal blower(s) of forward curved multi-blade type shall be fitted to the air conditioning unit. Blower shall be statically and dynamically balanced and shall be rust proofed. Blower shall be run on a common shaft mounted on self-aligning bearing. Bearings shall be sized for load imposed and shall be either permanently lubricated type or fitted with accessible greasing points.

Remote Controller

LCD wireless remote controller shell be operated in 3 operation modes (cool, dry and fan), fan speed control (Low/Med/High/Auto), 24 hours auto start/stop timer and clock, and on/off air swing control.

Pros & Cons

Pros:

• Efficient cooling with multiple compressors
• Robust construction
• Versatile installation options

Cons:

• High initial cost
• Potential coolant compatibility issues

FAQ

What types of fan coil units are suitable for multi-split condensing units?

Multi-split condensing units are suitable for wall-mounted, ceiling-concealed, ceiling cassette or ceiling exposed fan coil units.

How are refrigerant circuits of multi-split units constructed?

Refrigerant circuits are constructed using copper piping with brazed connections, including components such as compressors, condenser coils, filter driers, sight glasses, thermo-expansion valves, and evaporator cooling coils.

What safety features are included in multi-split condensing units?

They feature high-pressure and low-pressure cutouts, crankcase heaters and anti-recycling timers to ensure safe and efficient operation.

Conclusion

Efficient multi-split condensing units provide reliable cooling solutions for a wide variety of applications, combining advanced technology with robust construction. Despite their initial cost and potential challenges with refrigerant compatibility, they offer efficient performance and ease of installation, making them a preferred choice for a variety of refrigeration needs.
