LHD Air Conditioning — Performance Testing in Mooinooi
This page covers lhd air conditioning in Mooinooi, eastern mining corridor within the Rustenburg mining belt. Measured verification of pressures, temperature split and airflow so system condition is a recorded number, not an opinion. Long travel distances between pit, plant and workshop mean cabin doors stay shut and air conditioning runs continuously through the shift — compressor and clutch wear tends to show earlier than on short-cycle machines.
LHDs in the Rustenburg belt
LHD HVAC repairs arranged through Rustenburg should use the planned surface maintenance window to inspect rock-contact damage and wet electrical connections. A cabin that cools while dry in the workshop may still lose airflow through saturated filters underground. Checking drainage, guarding and sealing alongside the refrigerant circuit makes the release test more relevant to the next tramming shift.
Typical specification
14 000 – 22 000 BTU/h typical cabin duty
Underground ambient conditions combine heat with high humidity, so a functioning system controls both temperature and moisture. Operators working long tramming cycles in that environment are directly affected when cooling degrades, and dust control depends on keeping the cabin closed.
Common problems in this application
- Impact and rock damage to condensers, guards and exposed hoses
- Continuous water ingress and drain blockage in humid workings
- Refrigerant loss at vibration-fatigued fittings
- Corrosion of coils and mountings from washdown and mine water
