to granule and to grid, and then to heat carrier in the hydraulic circuit and to consumer.
Heat supply to evaporator is carried out by finned warmer (8).

On the second stage when regeneration occurred distributing checker 10 is closed.
Heat from external source (solar collector) is transferred through the hydraulic circuit
to one-side finned grid and to granules of adsorbent placed in cylindrical rings with
heat condensation emission, and then to heat carrier which is supplied to the consumer
or warmed in the hydraulic circuit and applied for adsorbent regeneration. The
condensate flows down to the evaporator by radial-vertical fibs through narrowed neck
to the evaporator.
Calculation of the mass of the adsorbent and water which are necessary for
adsorptive heat pump operating is carried out similarly to the adsorptive heat storage
device [11].
Adsorptive heat pump was tested through February 2016. Period-averaged day
changes of temperature of adsorbent, adsorbate and pressure in the system are given
on a Fig. 8.
