Heat exchangers are a key component of this machine, they must provide maximum heat transfer surface area relative to internal volume, while minimising pressure drops. So far, only microtube heat exchangers have been considered. The cylinders and pistons are made from a material with low thermal conductivity. The piston kinematics can be achieved using various methods, achieving maximum efficiency requires a complex motion which can be accurately approximated using a 6-bar linkage, while a simple crank-connecting rod system will allow operation at reduced efficiency. For refrigeration applications, numerous mechanisms are possible, such as cams, actuators, solenoids, etc.
