Direct Current Compressor (DCC)

Air Conditioning

(P1 2014 700909)

PRODUCT DESCRIPTION / FEATURES

The compressor of the automotive air conditioning is drive by an electric motor which in turn is operated by electric battery (12Volt). The system operating with inverter and an intelligent controller installed to vary the speed of the compressor for load matching and thermal comfort.

NEEDS

Capability of controlling DCC for the automotive/vehicle air conditioning system with the variable-speed operation.

Ability to match the performance of DCCfor automotive /vehicle air conditioning system with the cooling load.

Temperature controller based on the present value of fuzzy logic control.

Simple installation and maintenance together with the potential to conserve energy.

APPROACH

The automotive air conditioning compressor (AAC) is belt-driven by the engine. The compressor speed is directly proportional to the engine speed. Therefore, the cooling capacity will vary as the engine speed changes.

To meet the air conditioning (AC) demand, the compressor continually cycles on and off. In the research, the compressor of the AAC is driven by an electric motor which in turn is operated by electrical battery (12 volt).

The use of direct current compressor (DCC) is seen as a solution of the existing system. Using the proposed system, DCC gets significant improvements in energy efficiency.

Compared with AAC system, the energy conservation effect is about 77.5% to 86.35%.

BENEFITS

Relieves the internal combustion engines from driving air- conditioning compressors, thus enable to contribute towards energy saving.

Environmental-friendly features in modem passenger core

COMPETITORS

Replacement of conventional (belt-driven) automotive/vehicle air conditioning systems with DCC.

Replacement of the conventional control systems in conventional automotive/vehicle air conditioning systems with the intelligent control system
