Title:

HEAT EXCHANGING METALLIC PIPE AND ADSORPTION TYPE HEAT PUMP

Document Type and Number:

Japanese Patent JP3440250

Kind Code:

B2

Abstract:

PURPOSE: To provide an adsorption type heat pump capable of performing an adsorption and desorption of adsorptive material in an adsorptive tower within a short period of time.
CONSTITUTION: A heat exchanging metallic pipe 11 has a central hole 13 where heat exchanging fluid can flow through it and a fixed layer 15 in which an adsorptive material 14 is fixed to an outer circumferential surface. The fixed layer 15 is formed by crushing silicagel acting as adsorptive material 14 into 42 meshes, mixing them with binder of vinyl acetate, adhering the mixed material to an outer circumferential surface of a copper tube 17 and sintering it at 110°C for 6 hours. A plurality of heat exchanging metallic pipes 11 are arranged at an adsorptive tower of an adsorptive type heat pump in such a manner that a space where water acting as working fluid can flow is left there, thereby after there occurs a temperature variation through adsorption or desorption of the adsorptive material, a heat exchanging operation is efficiently carried out, the working fluid is uniformly dispersed within the adsorptive tower and no substantial deflection may occur in a distribution of an amount of adsorption. With such an arrangement as above, as compared with the prior art adsorptive type heat pump, a time required for one cycle is shortened.
