Abstract

Various embodiments described herein relate to a test chamber device an associated methods and non-transitory machine-readable media including a test chamber, a system builder that is configured to build and apply an equipment load to the test chamber; a load maker that is configured to build and apply a predefined load to the test chamber; and a tester which measures action of the equipment load and the predefined load within the test chamber, producing a test state.

Claims (35)

1 . A method of determining test chamber behavior comprising a test chamber, a system builder, and a weathermaker system, the weathermaker system included in a system comprising a processor and a memory, the method comprising:

configuring the system builder, creating a system builder configuration;

applying a control sequence generated using a digital twin to the system builder configuration to create a first dynamic load in the test chamber;

using the processor and memory to determine a second dynamic load producing a determined second dynamic load;

configuring the weathermaker system using a temperature curve to create the determined second dynamic load in the test chamber; and

using an interaction of the first dynamic load and the second dynamic load in the test chamber to determine test chamber behavior.

2 . The method of claim 1 , wherein configuring the system builder comprises multiple pieces of equipment, and further comprising configuring at least one of the multiple pieces of equipment using a two-way valve matrix.

3 . The method of claim 2 , wherein the test chamber behavior comprises state in the test chamber when the first dynamic load and the second dynamic load are simultaneously in the test chamber for a determined amount of time.

4 . The method of claim 3 , wherein the test chamber allows state distribution, and wherefore the state distribution comprises radiant state distribution, air state distribution, or convection state distribution.

5 . The method of claim 4 , wherein determining the state in the test chamber comprises determining when the second dynamic load balances the first dynamic load.

6 . The method of claim 5 , wherein determining when the second dynamic load balances the first dynamic load comprises determining when the state of the second dynamic load is equal to the state of the first dynamic load.

7 . The method of claim 6 , wherein the state of the first dynamic load is temperature.

8 . The method of claim 1 , wherein the system builder uses the digital twin to create the system builder configuration.

9 . The method of claim 8 , wherein the digital twin comprises interconnected nodes, and wherein state modification flows between the interconnected nodes.

10 . The method of claim 1 , wherein the system builder comprises system builder equipment and a system configuration matrix that attaches the system builder equipment to each other and attaches the system builder equipment to the test chamber.

11 . A system comprising a memory and a processor, wherein the processor is in communication with the memory configured to:

configure a system builder, creating a system builder configuration;

apply a control sequence generated using a digital twin to the system builder configuration to create a first dynamic load in a test chamber;

use the processor and memory to determine a second dynamic load producing a determined second dynamic load;

configure a weathermaker system using a temperature curve to create the determined second dynamic load in the test chamber;

use an interaction of the first dynamic load and the second dynamic load in the test chamber to determine test chamber behavior;

wherein the system builder comprises system builder equipment and a system configuration matrix that attaches the system builder equipment to each other and attaches the system builder equipment to the test chamber;

wherein the system builder equipment comprises at least two of a heating and cooling section, a pumping section, a storage section, a heat exchange section, and a mixing section;

wherein the test chamber comprises a chamber and test chamber equipment, and wherein the test chamber equipment provides test state distribution, the test state distribution comprising radiant state distribution, air state distribution, or convection state distribution;

wherein test chamber equipment comprises an air handler, a variable air chamber box, a radiant floor, or a radiator to apply a predefined load; and

wherein the test chamber is substantially covered in a hydronic shroud.

12 . The system of claim 11 , wherein the first dynamic load and the second dynamic load are applied to the test chamber simultaneously.

13 . The system of claim 12 , wherein the control sequence is developed using a building model to produce a load curve.

14 . The system of claim 11 , wherein configuring the system builder comprises multiple pieces of equipment, and further comprising configuring at least one of the multiple pieces of equipment using a two-way valve matrix.

15 . The system of claim 14 , wherein the test chamber behavior comprises state in the test chamber when the first dynamic load and the second dynamic load are simultaneously in the test chamber for a determined amount of time.

16 . The system of claim 15 , wherein the test chamber allows state distribution, and wherefore the state distribution comprises radiant state distribution, air state distribution, or convection state distribution.

17 . The system of claim 16 , wherein the test chamber equipment further comprises a hot water tank and a cold water tank, and wherein the hot water tank and cold water tank are configured to provide dynamic heating and cooling to the hydronic shroud.

18 . The system of claim 17 , wherein the system builder equipment further comprises at least two of a heating and cooling section, a pumping section, and a storage section.

19 . The system of claim 18 , wherein the system configuration matrix comprises multiple two way valves.

20 . The system of claim 19 , wherein a load maker creates a zone mass using a buffer tank.
