Title:
HEAT ACCUMULATIVE TYPE COOLING OR HEATING DEVICE
Document Type and Number:
Japanese Patent JPS6457063
Kind Code:
A
Abstract:

PURPOSE: To enable a heat accumulative operation and a cold heat accumulative operation to be carried out at an appropriate temperature level in a relatively less amount of heat loss by a method wherein there is added a heat accumulative device utilizing a phenomenon of absorbing heat or generating heat accompanying a reversible chemical reaction.

CONSTITUTION: In the case that a heat accumulative operation is carried out, a cold heat accumulating operation and a heat accumulating operation are determined by selecting either a heat absorbing operation or a heat generating operation during its use and they are the same from each other. A first four-way valve 7 and a second four-way valve 8 are denoted by a solid line, all the opening or closing valves a12, b13 and c14 are opened and no heat exchanging operation is carried out at an outdoor heat exchanger 2 and an indoor heat exchanger 3. A flow of refrigerant passes from a compressor 1 through the first four-way valve 7 and the second four-way valve 8 via the outdoor heat exchanger 2, a container B11, a branch point 9 and a container A10 and further the refrigerant is returned back to the compressor 1. At this time, the container B11 is exposed to a high temperature and the container A10 is exposed to a low temperature, so that adsorbing agent in the container B11 is heated to desorb operating medium, the discharged operating medium is condensed in the container A10 and stored. When the stored amount becomes sufficient, the operation is stopped, the opening or closing valve a12 is closed to keep the adsorbing agent and the operating medium in separated state.
