✦ Synopsis

A chemical heat pump system with paraldehyde/acetaldehyde (Pa/A) is proposed for a cooling system. This chemical heat pump is similar to the vapor-compression heat pump. The coecient of performance (COP) was estimated from equilibrium data. The coecient of performance (COP) was estimated from equilibrium data. The pressure and the concentration at the reaction equilibrium state were measured for estimation of the performance of the CHP. The COP of the Pa/A system is same as the COP of a vapor-compression heat pump with CFCs.
