In this study, a newly system is designed and tested which integrates air-to-water heat pump and solar air collector having fabric absorber for the shortcoming of frost depositing on the evaporator in heating condition. ...

The fact that diffusion absorption refrigeration (DAR) systems can also work with low power plants has increased the interest in these cooling systems again. The DAR systems are mostly analyzed using energy analysis. ...

In this study, a coal-fired stoker boiler and a beta-type rhombic-drive Stirling engine were manufactured and tested. The performance of the coal boiler with a Stirling engine has been investigated experimentally for the ...
