## Abstract

A system and a method for calculating in real time, actual realized savings that a cooling system obtains from addition of a thermal storage capability to the cooling system, compared to a model of the system without the added thermal storage capability.

## Claims

### Claim 1

A computerized method for real cost analysis related to a modification of an existing cooling system, comprising:
a computer processor determining a base real cost per time period of the existing cooling system;
the computer processor generating an estimated real cost per time period of a model using the modification to the existing cooling system; and
the computer processor comparing the base real cost per time period to the estimated real cost per time period.

### Claim 2 (depends on 1)

The computerized method according to claim 1, wherein the computer processor determining the base real cost per time period of the existing cooling system comprises:
determining values for a temperature, a flow measurement, a fluid type in a solution, and a fluid percentage in the solution.

### Claim 3 (depends on 1)

The computerized method according to claim 1, wherein the computer processor determining the base real cost per time period of the existing cooling system comprises:
the processor determining a chiller leaving temperature, and an entering condenser temperature.

### Claim 4 (depends on 3)

The computerized method according to claim 3, wherein the entering condenser temperature includes an entering air temperature.

### Claim 5 (depends on 3)

The computerized method according to claim 3, wherein the entering condenser temperature includes a water temperature.

### Claim 6 (depends on 1)

The computerized method according to claim 1, further comprising the computer processor determining heat per unit time.

### Claim 7 (depends on 1)

The computerized method according to claim 1, wherein the computer processor generating the estimated real cost per time period of the model comprises:
the processor using the values for the temperature, the flow measurement, the fluid type in the solution, and the fluid percentage in the solution.

### Claim 8 (depends on 1)

The computerized method according to claim 1, wherein the computer processor generating the estimated real cost per time period of the model comprises:
the processor determining a chiller leaving temperature, and an entering condenser temperature.

### Claim 9 (depends on 8)

The computerized method according to claim 8, wherein the entering condenser temperature includes an entering air temperature.

### Claim 10 (depends on 8)

The computerized method according to claim 8, wherein the entering condenser temperature includes a water temperature.

### Claim 11 (depends on 1)

The computerized method according to claim 1, further comprising:
the computer processor outputting to a display a result of the real cost analysis related to the modification.

### Claim 12 (depends on 1)

The computerized method according to claim 1, wherein the modification includes an addition of a thermal storage capability.

### Claim 13 (depends on 1)

The computerized method according to claim 1, wherein the modification includes a removal of a thermal storage capability.

### Claim 14 (depends on 1)

The computerized method according to claim 1, wherein the computer processor comparing the base real cost per time period to the estimated real cost per time period is performed in real time.

### Claim 15 (depends on 1)

The method according to claim 1, wherein the modification is an actual modification.

### Claim 16 (depends on 1)

The method according to claim 1, wherein the modification is a hypothetical modification.

### Claim 17

A system for real cost analysis related to a modification of an existing cooling system, comprising:
a processor;
a memory in communication with the processor and having stored therein a computer readable instructions executable by the processor, wherein when executed by the processor, causes the processor to carry out:
determine a base real cost per time period of the existing cooling system;
generate an estimated real cost per time period of a model using the modification to the existing cooling system; and
compare the base real cost per time period to the estimated real cost per time period.

### Claim 18 (depends on 1)

A computer readable medium storing therein a computer readable instructions for a processor, wherein when the computer readable instructions is executed by the processor, the processor carries out the method according to claim 1.
