Abstract

A comparison of the coefficient of performance (COP), the specific cooling power (SCP) and the reactor volume per output power was carried out with numerous salt-ammonia couples for single effect solid-gas chemical heat pumps. Optimal reaction couples could be selected in terms of COP, SCP and reactor volume at each application domain of deep freezing (-15~-20℃), ice making (-10~-5℃) and air conditioning (0-10℃).
