Abstract
In a heat pump, e.g. comprising two adsorbers (1, 2), the adsorbers are monoliths having a multiplicity of open cells capable of flow-through of gas or vapor, and having a coating of an adsorbent, e.g. zeolite, for a fluid such as water vapor. Waste heat, e.g. from a vehicle engine, is supplied to heater (3), which heats up a heat transfer fluid pumped around the system by a reversible pump (11). Heat is lost to the ambient air by a cooler (4), and air from ambient, or recirculated air, is cooled by passing over an evaporator (6) for adsorbate fluid such as water, before entering a vehicle passenger compartment.
