Passenger space heating - and - climate tisi will tend for motor vehicles having a motorkuehlsystem with a low kuehlmitteltemperatur

摘要

An apparatus and system is disclosed for extracting heat units from a relatively lower temperature zone of a cooling system for a Stirling engine and conveying said heat units to a relatively higher temperature zone serving as the passenger compartment of a vehicle. The system is reversible for either heating or cooling of the passenger compartment. The system makes it possible to employ waste heat units of the Stirling engine cooling system even though the average temperature of such cooling system is 60° F or less.
