Heat pump according to the adsorption principle

摘要

The invention relates to a heat pump according to the adsorption principle, comprising a plurality of hollow elements each having an adsorbent, wherein a working medium is enclosed in each of the hollow elements is displaceable between the adsorbent and a phase change area, wherein a heat-transporting fluid in a variable fluid circuit can flow through the hollow elements by means of a valve arrangement. The hollow elements are brought into thermal contact with the fluid in the area of the adsorbent, wherein the flow through the hollow elements changes cyclically with the fluid, wherein at least two of the hollow elements are flown through parallel from the fluid at least in one, in particular each position of the valve arrangement, and at least two of the hollow elements are flown through serially one after the other.

1. An heat pump comprising:
a plurality of hollow elements, wherein each hollow element encloses a phase change area comprising a capillary structure and an adsorber area comprising an adsorbent, wherein the adsorber area and the phase change area further enclose a working medium that is displaceable between the adsorbent area and the phase change area, wherein the working medium enclosed in the phase change area and the adsorber area is fluidically divided from remaining portions of the plurality of hollow elements, wherein a heat-transporting fluid flows through the remaining portions of the plurality of hollow elements in a first circuit and a second circuit, wherein in the first circuit the heat-transporting fluid passes through a first flow channel permeating each hollow element of the plurality of hollow elements which are brought into thermal contact with the adsorber areas, wherein in the second circuit the heat-transporting fluid passes through a second flow channel permeating each hollow element of the plurality of hollow elements which are brought into thermal contact with the phase change areas, wherein the heat-transporting fluid of the first circuit and the second circuit flows through the plurality of hollow elements in a fluid circuit which is varied by a valve arrangement, wherein the flow of the heat-transporting fluid through the plurality of hollow elements changes cyclically, wherein each position of the valve arrangement, heat-transporting fluid flows in parallel through at least two of the hollow elements of the plurality of hollow elements in each of the first circuit and the second circuit, wherein the flow passes serially in succession through at least two of the hollow elements of the plurality of hollow elements in each of the first circuit and the second circuit, wherein a number of hollow elements through which there is a parallel flow corresponds at least approximately to a quarter of the number of hollow elements of the plurality of hollow elements through which there is a serial flow in each of the first circuit and the second circuit.
