## Abstract

The present disclosure discloses a solar powered thermally conditioned space, which, in an embodiment, may be used to provide a cold storage arrangement for preservation of perishable commodities over an extended time period. The cold storage arrangement (10) includes a refrigeration unit mounted within a non-insulated compartment for circulating refrigerated de-humidified air to an insulated compartment. A chamber (12) defines the insulated compartment and the non-insulated compartment. The cold storage arrangement (10) is operated by a powering system powered by solar energy from solar panels mounted over a roof of the chamber (12).

## Claims

### Claim 1

A cold storage arrangement for preservation of perishable commodities over an extended time period, said arrangement comprising:
a chamber covered by a ceiling;
an insulated partitioning wall adapted to partition said chamber into an insulated compartment and a non-insulated compartment,
a pair of opposing vents defined on said non-insulated compartment for inlet and outlet of atmospheric air;
a refrigeration unit mounted on said insulated partitioning wall, said refrigeration unit adapted to coolingly circulate refrigerated de-humidified air to said insulated compartment via a duct, said insulated compartment adapted to be maintained at a desired temperature;
an air filtration unit adapted to filter the atmospheric air entering through one of said vents to form filtered atmospheric air, said filtered atmospheric air adapted to withdraw heat from said refrigeration unit and is expelled to the environment; and
a powering system housed within said non-insulated compartment, said powering system adapted to receive power from at least an array of solar panels supported on said ceiling, said powering system adapted to controllably charge a battery bank, having at least one battery, via an inverter.

### Claim 2 (depends on 1)

The arrangement as claimed in claim 1, wherein said insulated compartment includes an insulated door with a product discharge door for movement of the commodities into and out of said insulated compartment.

### Claim 3 (depends on 1)

The arrangement as claimed in claim 1, wherein said non-insulated compartment includes an access door for repair and maintenance.

### Claim 4 (depends on 1)

The arrangement as claimed in claim 1, wherein said refrigeration unit includes a condenser, a compressor and an evaporator enclosed with a cabinet, said cabinet being made of a high density polymer shell.

### Claim 5 (depends on 1)

The arrangement as claimed in claim 1, wherein said battery bank is further adapted to be charged by a mains AC supply through a convertor, said battery bank being adapted to receive at least a continuous power supply and an intermittent power supply from the mains AC supply.

### Claim 6 (depends on 5)

The arrangement as claimed in claim 5, wherein said convertor is selected from the group consisting of a rectifier, an AC/DC converter, a transformer and switched-mode power supply.

### Claim 7 (depends on 1)

The arrangement as claimed in claim 1 further includes a battery health indicator adapted to indicate a level of charge in each of said batteries and an overall charge of said battery bank.
