Title: Cooled latent heat accumulator for space heating and cooling by means of direct solar energy or indirect solar energy held in the water
Inventor: KLAMI PAAVO VEIKKO DR MED
IPC: F25B29/00
Filed: 1982-01-26
Abstract: In order to achieve a heat pump effect, which is as infinitely variable as possible, in addition to numerous, different types of small compressor (see German patent application, file ref. P 3109443.0), a very large number of simple diaphragm pumps are also proposed. These compressor components comprise two elastic diaphragms which are hermetically joined at their periphery, and the middle and/or periphery of which are mechanically driven, for example by electric motors or series of magnets, so that each pair of diaphragms is separated from one another during the suction cycle and compressed during the working cycle. In order to prevent heat losses from the heat pump system to the outside and directly recover internal losses occurring between phases, the short-term accumulator containing the water is enclosed by the warmest phase of the heat pump and this in turn by the next warmest phase. The outermost or coldest phase can be uninsulated against warmer surroundings (cellars or the like).

Patent DE-3206707-A1 (DE)
Title: Control method for matching the heating heat supply of absorption heat pumps with fixed throttles
Inventor: MALEWSKI WERNER DR ING
IPC: F25B49/04
Filed: 1982-02-25
Abstract: The invention relates to a method of controlling the heating heat supply in absorption heat pumps and refrigeration units, when these are equipped with fixed throttles for the expansion of the liquefied working medium to the evaporation pressure. In small units, the incorporation of fixed throttles is preferred, so that the matching of the quantity of refrigerant takes place only in the framework of the pressure difference between the high pressure and low pressure sides. Thus a full loading of the evaporator is only ensured when the absorption process is matched by an altered supply of heating medium. This is solved according to the invention in that the superheat temperature of the refrigerant vapour at the outlet of the evaporator is selected as a measure of the evaporator loading and as a control variable for the heating medium supply. Moreover, independently of this, the feed temperature of the heat uptake side can be controlled via the volume flow of the heat carrier through the absorption system. The two independent control circuits are shown in the diagram. The use of the invention is limited to compact small units, which must manage with fixed throttles. <IMAGE>
