AIR CONDITIONING SYSTEM


  1. CONSTRUCTION


    1. A fixed capacity swash plate type 10SRE15C*1 or 10S15C*2 compressor is used.


      • *1: Models with 2TR-FE, 1GR-FE, 1GD-FTV, 2GD-FTV engine

      • *2: Models with 1KD-FTV, 2KD-FTV, 5L-E engine

    2. On models with 10SRE15C compressor, a rotary valve that intakes refrigerant directly into the cylinder is used, achieving a reduction in refrigerant intake loss.

    3. On models with 10SRE15C compressor, a shaft oil separator that separates compressor oil from the refrigerant is used.


      1. Compressor oil, which has been mixed with the refrigerant and circulated in the air conditioning cycle, is separated by the shaft oil separator built into the shaft and accumulated in the compressor.

      2. For the shaft oil separator, an oil return passage is located between the cylinder and the lug plate, and refrigerant gas in which a small amount of oil is mixed is sent to the intake chamber. As a result, the oil circulation amount in the air conditioning cycle is reduced.

    4. Rotary Valve


      1. The rotary valve has a structure where refrigerant passing through the center of the hollow shaft is taken into the compression areas within the cylinder. The intake of refrigerant occurs when the openings of the shaft and cylinder overlap.
