Cooling method and system therefor

Claim 2

A cooling method comprising: removing sensible heat from a cooling load including air in a room by cooling means (11) having cooling surfaces in said room to be cooled, by receiving and circulating within said cooling means a circulating cooling medium evaporated in an absorption refrigerator (7) utilizing a heating medium, said circulating cooling medium being received from said absorption refrigerator; dehumidifying said air by circulating said air through a dry type dehumidifier (13); utilizing said heating medium to regenerate the dehumidifying function of said dry type dehumidifier; and blowing the resulting dehumidified air on said cooling surfaces of said cooling means (11) in a direction substantially parallel to said cooling surfaces, whereby the formation of condensate on said cooling surfaces is avoided.

Claim 3

The cooling method of claim 1, wherein said dehumidified air is blown against said cooling surfaces in a direction slightly inclined from said surfaces, and circulated.

Claim 4

The cooling method of claim 1, wherein said cooling means (11) are mounted on the ceiling of said room.

Claim 5

The cooling method of claim 1, wherein said cooling means (11) are mounted adjacent the ceiling of said room.

Claim 6

The cooling method of claim 1, wherein said cooling means (11) comprises a panel type cooler.

Claim 7

The cooling method of claim 1, comprising heating said heating medium by solar energy.

Claim 8

The method of claim 1, wherein said heating and cooling media comprise water.

Claim 9

The method of claim 1, comprising heating said heating medium to up to 100° C. by means of industrial waste heat.

Claim 10

The method of claim 1, wherein said cooling medium is evaporated in vacuum.

Claim 11

The method of claim 1, wherein cooling fluid is recirculated between said refrigerator (7) and a storage tank (8) and said cooling means (11).

Claim 12

The method of claim 1, comprising cooling a load consisting of a mixture of air extracted from said room and outside air.

Claim 13

The method of claim 1, carried out when the outside temperature is only slightly higher than the temperature in said room and the absolute humidity does not exceed 15 g/kg' comprising dehumidifying outside air only, supplying said air to said room, extracting air from said room and venting same without dehumidification.

Claim 14

A cooling system comprising, in combination: a heat storage tank containing a heating medium; means for heating said heating medium; an absorption refrigerator receiving said heating medium, and cooling same; a cooler having a panel having a large area exposed in a room to be cooled; conduit means for bringing said heating medium as a cooling fluid from said absorption refrigerator to said panel; a dry-type dehumidifier for dehumifying air in said room by utilizing thermal energy from said heating medium, said dehumidifier comprising a housing, a columnar rotor in said housing, said rotor comprising a honeycomb block formed of corrugated layers of material containing adsorbents, and means for flowing heated air and dehumidified air in opposite directions; outlet means connected to said dehumidifier for blowing said dehumidified air from said dehumidifier substantially parallel to said panel to avoid condensation thereon; and a heating device connected to said heat storage tank, for heating air to produce said heated air, and conduit means for conducting air thus heated to said adsorbents to regenerate said adsorbents.

Claim 15

A cooling system comprising, in combination: a heat storage tank containing a heating medium; means for heating said heating medium; an absorption refrigerator receiving said heating medium, and cooling same; a cooler having a panel having a large area exposed in a room to be cooled; conduit means for bringing said heating medium as a cooling fluid from said absorption refrigerator to said panel; a dry-type dehumidifier for dehumifying air in said room by utilizing thermal energy from said heating medium, said dehumidifier comprising a housing, a columnar rotor in said housing, said rotor comprising a honeycomb block formed of corrugated layers of material containing adsorbents, and means for flowing heated air and dehumidified air in opposite directions; outlet means connected to said dehumidifier for blowing said dehumidified air from said dehumidifier substantially parallel to said panel to avoid condensation thereon; and a heating device connected to said heat storage tank, for heating air to produce said heated air, and conduit means for conducting air thus heated to said adsorbents to regenerate said adsorbents.

Claim 16

The system of claim 13, wherein said means for heating said medium consists of a solar energy collector or a source of waste industrial heat.

Claim 17

The system of claim 13, wherein said adsorbents consist of activated carbon or fibers thereof.
