— Simple HPD ($521.31) originally cost more than SAHPD ($892.94). SAHPD has a lower operating cost than a heat pump dryer. The heat pump dryer's annual cost was $1560, whereas the SAHPD's was $1462. So, on exergoeconomic factor, the SAHPD is improved as 528 compared to heat pump dryer, and the payback period is 24 months for …
