Condenser By exchanging heat with air, the condenser cools the high-temperature, high-pressure gas refrigerant sent from the compressor and condenses it into liquid refrigerant. This heat exchange allows the air conditioning system to emit the heat absorbed by the evaporator from inside the vehicle to the outside. DENSO’s high-performance condenser reduces the required compressor power, resulting in improved fuel economy.

DENSO Technology – Leading the World

• In 1996, DENSO introduced a condenser that integrated the condenser and subcooler. This condenser was the first in the world to have the modulator (receiver) integrated with the condenser tank (see below).
• In 2002, DENSO introduced a new condenser with a subcool part, featuring the world’s thinnest tube (1 mm) and lowest fin height (5.4 mm).

Benefits and Features

• High performance
  • The subcooler integrated with the condenser further cools the liquid refrigerant, resulting in increased refrigerant enthalpy and improved evaporator cooling performance.
  • Thinner tubes and fins improve the heat exchange rate.
    Smaller header tank and lower side plate height increase the effective heat exchange area of the core part that exchanges heat, without increasing the installation space.
• Small size, light weight and easy installation
  • Integrated modulator with condenser tank.
  • The tube’s zinc diffusion layer improves corrosion resistance, resulting in reduced tube plate thickness.

Condenser with a Subcooler Part

How it works:

• The condenser part cools the high-temperature, high-pressure gas refrigerant sent from the compressor, and condenses it into liquid refrigerant.
• The modulator separates gas and liquid refrigerants and sends the liquid refrigerant to the subcooler part.
• Using desiccant and a filter, the modulator removes moisture and foreign material from the refrigerant.
• The subcooler part further cools the liquid refrigerant to increase the refrigerant enthalpy.
