Process and apparatus for modulating temperatures within enclosures

Claim 3

The process of claim 1 in which the cooling of said space is additionally affected by causing air unsaturated with said liquid to pass through the zone overlying said liquid and underlying said thermal barrier in its first position thereby evaporating part of said liquid and cooling the remainder thereof and in which a second body of liquid is cooled in its first location by thermal exchange with said liquid subjected to evaporation and in which said first or second body of liquid is transferred at least in part to a second location and there cooling at least partially enclosed space and in which said transfer is accomplished by circulatory means including thermosiphonic action.

Claim 4

The process for influencing the temperature of a first body of liquid heated in winter by solar radiation and cooled in summer by evaporation, wherein the steps are: (a) exposing the first body of liquid to solar irradiation while having said liquid enclosed in a relatively impermeable enclosure which permits passage of solar radiation through at least a portion of said enclosure overlying said liquid thereby raising the temperature of said liquid in winter, and (b) covering at least a portion of the enclosed liquid with an exposed second body of liquid in summer and evaporating a portion of the second body of liquid to cool it and, by thermal conductance through the impermeable enclosure, cooling said first liquid, and (c) removing said second body of liquid from above the impermeable enclosure in winter to allow solar radiation to heat the first body of liquid without an opposing cooling effect caused by the evaporation of a liquid.

Claim 5

The process for influencing the temperature of a first body of liquid heated in winter by solar radiation and cooled in summer by evaporation, wherein the steps are: (a) exposing the first body of liquid to solar irradiation while having said liquid enclosed in a relatively impermeable enclosure which permits passage of solar radiation through at least a portion of said enclosure overlying said liquid thereby raising the temperature of said liquid in winter, and (b) covering at least a portion of the enclosed liquid with an exposed second body of liquid in summer and evaporating a portion of the second body of liquid to cool it and, by thermal conductance through the impermeable enclosure, cooling said first liquid, and (c) removing said second body of liquid from above the impermeable enclosure in winter to allow solar radiation to heat the first body of liquid without an opposing cooling effect caused by the evaporation of a liquid.

Claim 6

In the process of claim 3, the improvement which comprises influencing the temperature of at least partially enclosed space by causing thermal exchange between said space and at least one of said bodies of liquid.

Claim 7

The process of zone control of air temperatures in at least two rooms having thermal exchange with a liquid in thermal contact with structural members forming said rooms, wherein the steps are: (a) pumping said liquid, during a first period, from a first position where thermal exchange with air of a first room is limited at least in part by air stratification through a heat exchange unit and forcing air out of said first room across said heat exchange unit in a manner reducing air stratification in said first room and causing the air therein to be closer to the temperature of said liquid, (b) discharging the liquid pumped through said heat exchange unit to a second position where thermal exchange with air in a second room is more limited by stratification during said first period, (c) pumping said liquid, during a second period, from its second position through a heat exchange unit and forcing air of the second room across this heat exchange unit thereby reducing air stratification in the second room and causing air therein to be closer to the temperature of the liquid pumped from said second position, and (d) discharging the liquid pumped through this heat exchange unit of the second room and returning said liquid by means provided to the first position where greater air stratification in the first room limits thermal exchange with air in the first room.

Claim 8

The process of zone control of air temperatures in at least two rooms having thermal exchange with a liquid in thermal contact with structural members forming said rooms, wherein the steps are: (a) pumping said liquid, during a first period, from a first position where thermal exchange with air of a first room is limited at least in part by air stratification through a heat exchange unit and forcing air out of said first room across said heat exchange unit in a manner reducing air stratification in said first room and causing the air therein to be closer to the temperature of said liquid, (b) discharging the liquid pumped through said heat exchange unit to a second position where thermal exchange with air in a second room is more limited by stratification during said first period, (c) pumping said liquid, during a second period, from its second position through a heat exchange unit and forcing air of the second room across this heat exchange unit thereby reducing air stratification in the second room and causing air therein to be closer to the temperature of the liquid pumped from said second position, and (d) discharging the liquid pumped through this heat exchange unit of the second room and returning said liquid by means provided to the first position where greater air stratification in the first room limits thermal exchange with air in the first room.

Claim 9

The process of claim 5 in which the temperature of said liquid is varied by temperature-influencing conditions external of said rooms and said liquid is circulated to a third position having no thermal exchange with air in said first or second rooms.

Claim 10

The process for influencing the temperature of a horizontally disposed body of liquid by movement of a thermal barrier from a first position overlying said liquid to a second position not overlying said liquid whereby said liquid is insulated from or exposed to conditions capable of influencing the temperature of said liquid, wherein the steps are: (a) adding a portion of said liquid within a confining means on the upper surface of said thermal barrier to subject it to temperature change while over this thermal barrier, (b) draining said portion from over said thermal barrier and co-mingling it with said body of liquid which underlies said thermal barrier in its first position, and (c) influencing the temperature of the co-mingled liquid by moving said thermal barrier from its first position to its second position.

Claim 11

The process for influencing the temperature of a horizontally disposed body of liquid by movement of a thermal barrier from a first position overlying said liquid to a second position not overlying said liquid whereby said liquid is insulated from or exposed to conditions capable of influencing the temperature of said liquid, wherein the steps are: (a) adding a portion of said liquid within a confining means on the upper surface of said thermal barrier to subject it to temperature change while over this thermal barrier, (b) draining said portion from over said thermal barrier and co-mingling it with said body of liquid which underlies said thermal barrier in its first position, and (c) influencing the temperature of the co-mingled liquid by moving said thermal barrier from its first position to its second position.

Claim 12

The process of claim 7 in which the confining means on the upper surface of said thermal barrier is an enclosure that prevents evaporation of said liquid while it is subjected to temperature change.
