As the penetration of renewable energy resources increases, their intrinsic uncertainty and randomness raise significant concerns about grid’s reliability. With development information technologies, residential air-conditioners serve increasing services, including secondary frequency regulation, peak load shaving, capacity reserve. However, these can hardly be allocated economically reliably. O...

A human life demand set to emerge in the future is the achievement of sustainability by maintaining a comfortable indoor environment without excessive reliance on energy-consuming air conditioners. The major research processes in this study are: (1) measuring indoor air quality and thermal comfort to evaluate the comfort of an indoor environment; (2) implementing questionnaire survey analysis t...

The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) recently completed the first phase of its low global warming potential alternative refrigerants evaluation program (Low-GWP AREP). This industry-wide cooperative research program identified and evaluated promising alternative refrigerants’ performance over the past two years. Thirty-eight low-GWP refrigerants were tested during t...
