ABSTRACT

Tropical or subtropical countries are very suitable for the development of solar and heat pump technology. This paper proposed the integration of air conditioners that exhaust heat with solar energy to enhance the overall efficiency of thermal energy conversion. The analysis of thermal storage tanks of different volumes showed that a two-ton air conditioner operating for an hour produced double energy than normal sunshine for a day. With thermal storage tanks of fixed volume, the integration of air conditioners of different tons with solar energy indicated that air conditioners of less tons produced faster and more efficient energy conversion. Therefore, this paper proposed that the modification of condenser in domestic air conditioner into water-cooled condenser not only enhance the energy efficiency of air conditioners but also increased hot water supplies since hot water from air conditioners could be integrated into solar water heaters. By doing so, energy conservation and carbon reduction could be achieved.

ABSTRAK

Negara-negara tropika atau subtropika sangat sesuai bagi pembangunan teknologi tenaga suria dan pam haba. Kertas ini mencadangkan perintegrasian penyaman udara yang menggunakan haba dan tenaga suria untuk meningkatkan kecekapan keseluruhan penukaran tenaga haba. Analisis tangki penyimpanan haba dengan isi padu yang berbeza menunjukkan bahawa penyaman udara dua tan yang beroperasi selama sejam menghasilkan tenaga dua kali ganda daripada cahaya matahari untuk satu hari. Dengan tangki penyimpanan haba dan isi padu yang tetap, integrasi penyaman udara daripada tan yang berbeza dengan tenaga suria menunjukkan bahawa penyaman udara dengan tan yang rendah cepat menghasilkan dan lebih cekap dalam penukaran tenaga. Oleh itu, kertas ini mencadangkan pengubahsuaian kondenser penyaman udara domestik ke kondenser pengairan sejuk bukan sahaja untuk meningkatkan kecekapan tenaga penyaman udara tetapi juga menambah bekalan air panas memandangkan air panas daripada penyaman udara boleh diintegrasikan ke dalam pemanas air suria. Dengan melakukan demikian, pemuliharaan tenaga dan pengurangan karbon boleh dicapai.

 

Kata kunci: Penyaman udara; penukaran tenaga; tangki penyimpanan haba; tenaga suria
