Car Air-Con



Condenser is a heat exchanger, which removes the heat of the high temperature and high pressure gaseous refrigerant supplied by the compressor and condenses it into a liquid. When the refrigerant is liquefied, it flows to the receiver dryer.



(1) Plate Fin Type

Plate types are large and have poor performance as tubing is expanded and mechanically connected after being inserted into the fin.

(2) Corrugated Fin Type

Corrugated fin types have better performance due to fins with a larger surface area in contact with air.

Corrugated fin type can be further divided into:

Serpentine Types (SP)

Serpentine type condensers are formed by bending tubing serpentinely with fins inserted between the tubing and brazed into place.

Serpentine type condensers now have two or three passes depending on the number of tubes installed to the joints, which reduces resistance inside the tubing and improves thermal efficiency.

Multi-flow Types (MF)

Multi-flow type condensers consist of layered and brazed fins and tubing.

In MF type condensers, refrigerant flows in the tubes at both ends of the tank simultaneously. As this reduces resistance within the tubes, the tubes can be thin, which allows many fins to be installed.

In addition, passes can be optimized by inserting partition plates inside the tank.

Various Multi-flow Types: (i) Subcool Type, (ii) Global Inner Fin Condenser Type (GIC)

Subcool Type

A multi-flow (MF) type condenser with an integrated gas-liquid separator (modulator).

In conventional receiver cycles, two-part gas-liquid refrigerant condensed in the condenser is separated by the receiver and only liquid refrigerant is sent to the evaporator.

The subcool type condenser is divided into a condensing section and a super-cooling section. Placing gas-liquid separator (modulator) between these the separated liquid refrigerant is cooled even further, thereby increasing the energy (enthalpy) held in the liquid refrigerant itself and improving cooling performance.
