HVAC

A unit that blows air with a motor-powered fan and conditions the air inside of a vehicle. It controls the amount of outside air, the temperature of the air, and the switching of outlet air. It also dehumidifies, cools, and heats air with a self-contained heat exchanger.

 

Keihin product features

  • Lightweight, compact and efficient - Air flow simulation techniques used during development reduces ventilation resistance that creates noise. Moreover, it contributes to low noise by simulating the breath of the blower which sends the fluid into the passenger compartment.

Customer benefits

  • Compact design allows a wider space in the passenger compartment
  • Weight saving contributes to lower fuel consumption
  • Possible to expand the basic package to other models

Condenser

The condenser in an HVAC system is used to condense a high-pressure refrigerant gas from its gaseous state to its liquid state by cooling it.

 

Keihin product features

  • Optimized to be thin and light - Miniaturization of the refrigerant passage and the louver of the heat dissipation fins optimizes heat exchange, making the condenser thin and light.

Customer benefits

  • Helps save space in the engine compartment

20170626_products_evaporator

Evaporator

The evaporator allows a high-pressure refrigerant to vaporize liquid to gas within the system while absorbing heat from the enclosed passenger compartment.

 

Keihin product features

  • Contributes to efficient cooling and reduction in size and weight - To prevent deterioration of cooling performance, Keihin has created a design that considers the routing of discharge water.
  • Allows cold air availability even when refrigerant circulation is not available - The design adopts a unique refrigerant circuit structure that takes into consideration the characteristics of the refrigerant that realizes an improvement in cooling efficiency and reduction in size and weight.

Customer benefits

  • Fits a wide range of vehicles

Cold accumulator evaporator

The cold accumulator evaporator is a cold storage tank that makes possible the continuation of cool air sent to the passenger compartment even when the engine is stopped/started.

 

Keihin product features

  • Contributes to efficient cooling and reduction in size and weight - To prevent deterioration of cooling performance, this evaporator considers the routing of discharge water.
  • Allows for cold air availability even when refrigerant circulation is not available - The evaporator adopts a unique refrigerant circuit structure that takes into consideration the characteristics of the refrigerant that results in an improvement in cooling efficiency and reduction in size and weight.

Customer benefits

  • Even, cool air flow during operation of the vehicle
  • Accumulated cold air allows for extended start/stop time and helps to decrease fuel consumption during vehicle operation.
