A heat pump using zeolite as an adsorbent wherein thermal energy from adsorbing zeolite in a one hermetically sealed space is used to heat desorbing zeolite located in another hermetically sealed space, such heat being conveyed by heat exchanger conduits containing a fluid which, before heating the desorbing zeolite, has its temperature increased to about 400°F. by a gas flame, the adsorption and desorption phases being changed between the zeolites in each cycle by reversing the fluid flow in the conduits. Cooling and heating for a building or other purposes are provided through the condenser and evaporator respectively for the working gas (water) which is desorbed and adsorbed into the zeolites. A propagating temperature front is established through the fluid-to-zeolite heat exchanger conduits to provide utilization of as much as ninety percent of thermal energy available during the desorption/adsorption phases.

A process for heating and cooling an interior space by using a low-grade heat source, the process comprising the steps of: 1. providing first and second pressure tight enclosures, each enclosure having a working refrigerant, an adsorbent material, a condenser and an evaporator therein, said adsorbent material being in thermal communication with a conduit which is provided for its respective enclosure, said adsorbent material being capable of adsorbing said refrigerant exothermically; 2. providing a low-grade heat source and means for it to be alternatively in thermal communication with said conduit for each said enclosure; 3. raising the vapor pressure of said refrigerant in said first enclosure and desorbing the refrigerant from said adsorbent material using said low-grade heat source; 4. allowing refrigerant vapor in said first enclosure to be received by said condenser therein, condensing said refrigerant vapor, and transferring said refrigerant\s heat of condensation to said internal space or to the atmosphere; 5. lowering the vapor pressure of said refrigerant in said second enclosure by adsorbing said refrigerant by said adsorbent, and transferring the heat of adsorption thereby generated to said first enclosure via said conduits; and 6. repeating steps 3, 4 and 5 in the opposite of said enclosures.
