1. Product introduction

The AC-05 cab air conditioning system produced by our company is a non-independent refrigeration system. This machine is suitable for various construction machinery such as road rollers, loaders, excavators, bulldozers, and graders.

2. Working principle

The compressor compresses the sucked superheated steam and then discharges it into the condenser through the pipeline. After heat exchange with the air in the condenser, it is condensed into supercooled liquid, and then it enters the evaporator after being pressure-reduced and throttled by the expansion valve. Absorb the heat in the cab, then enter the suction chamber of the compressor, and enter the next working cycle after compression. So repeatedly, the evaporator continuously absorbs heat from the cab to achieve a cooling effect.

4. Operation method

4.1. Control knob function:

A. Temperature control switch: used to adjust the compartment temperature during cooling.

B. Air volume switch: used to control the speed of the evaporator fan in order to select the appropriate air volume.

C. Indicator light: The green light is on to indicate that the compressor is started and the refrigeration system is in working condition.

The yellow light indicates that the power is on and the evaporation fan is in working condition.

The red light indicates that the air conditioning refrigeration system is faulty and in a stopped state. 

5. Matters needing attention

5.1. For the entire air-conditioning system, please do not disassemble it at will to prevent refrigerant leakage.

5.2. Check the tightness of the belt regularly to prevent it from being too loose or too tight.

5.3. Clean the surface of the condenser regularly to prevent the cooling effect from decreasing.

5.4. When replacing parts, the imported RL32H refrigerating oil should be added as specified in the following table.
