SYSTEM BUILDER

What else do I need?

Choose the route that matches your project. The compressor can replace a compatible unit, power a custom split system, or form part of a complete package.

1

Connect to existing A/C

Use the existing condenser, evaporator and controls only after confirming capacity, R134a compatibility, oil management, pressure protection and electrical load.

2

Build a new split system

Add the matched heat exchangers, protection, controls, hoses and mounting hardware shown below.

3

Choose a complete kit

If you do not want to engineer every component, start with a packaged system sized for the cabin and duty cycle.

Complete-system performance depends on the condenser, evaporator, controls, airflow, refrigerant charge and installation.

MD24A6: cooling and electrical input

MD24A6: voltage and compressor speed

Higher discharge pressure requires more voltage to reach the same compressor speed. Apply this graph only to the MD24A6 control version, not a PWM variant.

  • 1.8 MPa gauge
  • 2.2 MPa gauge
  • 2.5 MPa gauge

MD24A6 controller version shown. Discharge pressures are gauge values. These lines show the plotted voltage/speed relationship only; use the operating supply limits in the specifications for electrical design.

Discharge pressure Speed at 20 V Voltage at 6,000 rpm
1.8 MPa (gauge) 5,000 rpm 22 V
2.2 MPa (gauge) 4,000 rpm 23 V
2.5 MPa (gauge) 3,000 rpm 25 V

System requirements

Mount the MD24A6 upright with the controller uppermost, keep the housing clear of heat sources and maintain cool suction-gas return through the compressor. Run dedicated positive and negative power cables back to the battery and calculate cable size, circuit protection and charging capacity from worst-case current and cable length.

System components required Matched condenser, evaporator, expansion device, receiver-drier, thermostat/control, pressure protection and correctly sized refrigerant lines
Electrical design point Allow for compressor current plus condenser fans, evaporator blower and controls at the highest expected ambient and head pressure
Mounting orientation Upright only, controller uppermost; protect cables and refrigerant lines from abrasion, vibration and radiant heat
Commissioning Leak-test, evacuate, charge and validate operating pressures, voltage and current using qualified air-conditioning personnel

Technical selection: Use the exact compressor model, supply voltage and controller interface. Capacity values apply only at their stated test conditions; size the condenser, evaporator, wiring and protection as one system.
