Abstract
Abstract During the summer cooling season air conditioning equipment filters, cools and dehumidifies a home or other building. To minimize use of power on hot days during ''''brownouts'''' and ''''blackouts'''' the present invention operates for cold storage to store coolness produced at off-peak power periods. Additionally, the apparatus stores ''''dryness,'''' so that the air may be dehumidified, such as on hot muggy days, even when the refrigeration apparatus is shut off. And, coolness with dehumidification are achieved with lower overall power consumption because most of the ''''coldness'''' is produced during the cool night when the refrigerating equipment is more efficient. In the event the weather becomes too chilly on a cool summer night heat is automatically provided. Controls provide for automatic cooling and dehumidification 24 hours a day, plus automatic storage of coolness when not needed to meet the heat load, plus heating if needed. During the heating season solar produced heat, or heat from another source, is stored and used automatically as needed. Auxiliary heat also is automatically provided as needed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
89 words
Apparatus for cooling and storage of ''''coolness'''' comprising, first means for producing coolness in the form of cooled air, second means for storage of ''''coolness'''' for use at a later time, third means defining a space to be cooled by the cooled air, and fourth means to direct the cooled air from said first means directly to said second means and then to said third means, thence back to said first means for re-cooling to thereby further cool said storage means while not overcooling said space to be cooled.
Claim 2
Dependent Claim
89 words
Apparatus for cooling and storage of ''''coolness'''' comprising, first means for producing coolness in the form of cooled air, second means for storage of ''''coolness'''' for use at a later time, third means defining a space to be cooled by the cooled air, and fourth means to direct the cooled air from said first means directly to said second means and then to said third means, thence back to said first means for re-cooling to thereby further cool said storage means while not overcooling said space to be cooled.
Claim 3
Dependent Claim
21 words
Apparatus as in claim 1 and means to add heat in the event of overcooling in said space to be cooled.
Claim 4
Dependent Claim
40 words
Apparatus as in claim 1 wherein said first means comprises a refrigeration cooling means through which the air flows and the means for storage of coolness comprises a container of material through which the air flows for cooling said material.
Claim 5
Dependent Claim
19 words
Apparatus as in claim 3 wherein said material comprises a tank of liquid, and other storage material adjacent thereto.
Claim 6
Dependent Claim
43 words
Apparatus as in claim 1 wherein said means for storage of ''''coolness'''' also comprises a drying material capable of absorbing and liberating moisture from the air flowing therethrough to thereby dehumidify the air at periods when said first means is not producing ''''coolness.''''
Claim 7
Dependent Claim
33 words
Apparatus as in claim 1 and means for bypassing a portion of the air from said second means back to said first means for further cooling while reducing cooling of said third means.
Claim 8
Independent Claim
56 words
The method of cooling and storage oF ''''coolness'''' comprising the steps of cooling air, circulating the cooled air directly to a storage container for cooling the contents to thereby store ''''coolness,'''' then directing the air to a space to be cooled, and then directing the air back to the original point of cooling to be re-cooled.
Claim 9
Independent Claim
56 words
The method of cooling and storage oF ''''coolness'''' comprising the steps of cooling air, circulating the cooled air directly to a storage container for cooling the contents to thereby store ''''coolness,'''' then directing the air to a space to be cooled, and then directing the air back to the original point of cooling to be re-cooled.
Claim 10
Dependent Claim
28 words
The method of claim 7 and the further step of directing a portion of the air through heating means if the space to be cooled becomes too cool.
Claim 11
Dependent Claim
43 words
The method of claim 7 and the step of bypassing a portion of the air from said storage container back to the original point of cooling to be re-cooled thus further cooling said storage container while not overcooling said space to be cooled.
Claim 12
Dependent Claim
54 words
The method of claim 7 including cooling and drying the air, and circulating the cooled drier air to said storage container for cooling and drying the contents to thereby render the contents capable of absorbing heat and moisture at a later time to thereby cool and dry air passed therethrough at a later time.
