FIELD: energy.
SUBSTANCE: method in that working fluid is passed through at least one thermochemical heat accumulator, containing warmly heat-sink medium without contact with the last; wherein at charging heat accumulating medium is transferred into heat flow from working fluid medium and of heat accumulating medium is released at least one substance which is removed from heat accumulator, and at discharge of heat accumulating medium said substance is supplied with heat recovery in warmly heat-sink medium or in at least one product of reaction heat accumulating medium formed by charging, and heat flow is sent to the working fluid medium. At that charging heat accumulating medium is performed at low level of pressure, and its discharge is performed at increased pressure.
EFFECT: invention can be used in heat accumulators for heating and cooling of working fluid medium using at least one thermochemical heat accumulating medium.
