Abstract
A regenerative heating apparatus includes a radiating container and an adsorbent contained in the container. The adsorbent adsorbs vapor to generate heat when touched by the vapor, and releases the adsorbed vapor when heated. A heater for heating the adsorbent is disposed in the container. The vapor released from the adsorbent is condensed by a condensor and then fed into a liquid tank, thereby a dried adsorbent is produced. In a heating operation, the liquid in the tank is fed to an evaporator by a pump and evaporated thereby. The resultant vapor is fed to the dried adsorbent, and the adsorbent adsorbs the vapor to generate heat, thereby heating air around the container.
Claims12
A regenerative heating apparatus comprising:
- a radiating unit located in a place to be heated, said unit including a radiating container and an adsorbent contained in the container, for adsorbing vapor to generate heat when touched by the vapor and releasing the adsorbed vapor when heated;
- electric heating means for heating the adsorbent;
- a condenser located in the place to be heated, for condensing the vapor released from the adsorbent when the adsorbent is heated;
- a liquid tank containing a working fluid therein;
- an evaporator for evaporating the working fluid;
- guide means for guiding the working fluid, the guide means including a first pipe for guiding the working fluid from the tank to the evaporator, a second pipe for guiding the fluid from the evaporator to the radiating container, a third pipe for guiding the vapor released from the adsorbent to the condensor, a fourth pipe having one end connected to the condenser and the other end connected to the second pipe, and a fifth pipe having one end connected to the second pipe and the other end connected to the tank, so that fluid from the condenser may be guided to the tank through the fourth pipe, a part of the second pipe and the fifth pipe;
- valve means arranged in the guide means between the radiating container and the evaporator, for controlling the passage of the working fluid through the guide means;
- and
- ventilating means for forcedly ventilating the air in the place to be heated, through the region around the radiating container or the condenser, so as to heat the air.
