Chemical heat pump working according to the hybrid principle

Abstract

In a chemical heat pump installation two identical main units are provided, each one including a reactor and one condenser / evaporator integrated in the same container (100). One main unit is charged while the other one e.g. produces cooling. Large energy amounts are consumed in the switching operation when the unit that has been charged is to be cooled and the unit that has produced cooling is to be heated. To reduce these amounts of energy each of reactor and condenser / evaporator are divided in two further vessels. The condenser / evaporator has one part (3), in which the heat exchanger (3.3) thereof is placed, and one collecting part (4), in which the volatile liquid in its condensed shape is stored. In the same way, the reactor has a part (1), in which the heat exchanger (1.3) and the filter (1.2) thereof are placed, and a collecting part (2), in which solution of the active substance in the volatile liquid is stored. By this division only a small portion of the current mass has to change its temperature in the switching operations that hence can be made significantly more rapidly. A large gain in cooling efficiency can be obtained in an installation having two main units. Furthermore, no valves are required on the vacuum side.

Description

[0001] This application claims priority and other benefits from Swedish Patent Application No. 0303304-0 filed December 8, 2003, the contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a chemical heat pump working on the hybrid principle and a sprinkler or distributor for a heat exchanger, in particular to a spreading device for spraying liquid onto a heat exchanger of a chemical heat pump. Background technique [0003] In the chemical heat pump disclosed in published international patent application WO 00 / 37864, the chemical heat pump works according to a specific process, referred to herein as the hybrid principle, hybrid method, or hybrid process. [0004] In previously known heat pumps all energy is stored in the main unit. The main unit always works in equilibrium and is therefore always hot. In so-called slave units working completely independently of the master unit, the cooling or heating for the building...
