A method for transforming heat to a higher temperature and a heat transformer. By supplying heat of intermediate temperature T1 to a solid adsorbent at a low pressure, a previously adsorbed working fluid is desorbed from the solid adsorbent. The generated working fluid vapor is transformed to a liquid phase at a lower temperature T0 while releasing the phase changed heat. At relatively high pressure, heat is supplied to a liquid phase of the working fluid, which is transformed to the gaseous phase, which is then adsorbed in a solid adsorbent while liberating the heat of adsorption. The process is continued by alternately regenerating/saturating the solid adsorbent. The use of an absorbent fluid for changing the phase of the working fluid allows higher output temperatures and choice of the pressure levels used. An internal heat exchange method is included for the efficient use of the sensible heat of the solid adsorbent in systems with two or more containers with solid adsorbent.
