PACMAQ platform
Digital Systems
The PACMAQ instrumentalization platform is a functional demonstrator designed as part of the CORENSTOCK industrial chair, jointly coordinated with business EML Leblanc and IMT Nord Europe research centers.
Themes and challenges
- Heat pump control algorithm studies (PAC) [CERI SN]
- Standardized transfers and data set collection [CERI EE]
- Power consumption calculations [CERI EE]
- Consumption pattern data sets [CERI SN/EE]
- Testing of new more efficient and instrumented thermodynamic tanks [CERI MP]
This interdisciplinary platform (including physics and data processing reliant on algorithmic optimization) provides equipment that can be used for teaching, research and scientific popularization purposes.
Equipment
The PACMAQ platform has extensive monitoring equipment to ensure the smooth progress of our research and teaching activities, which cover several subject areas.
The model can be broken down into 4 main zones:
- The “HP” set consisting of a heat pump and thermodynamic tank (currently Bosch), temperature monitored
- The “Tanks” set consisting of tanks and all the control and monitoring equipment.
- The “Tarpaulin” set consisting of a closed-circuit water tank and the pressurized pump
- The “Robot” set featuring the wiring cabinet, IPC (control robot), and monitoring control station permitting transfer of all data to processing software (MATLAB, etc.).
This set facilitates the manual or automatic reproduction of sanitary hot water uses in a 4-person home and the domestic use of a thermodynamic tank to produce it. To do so, it has 4 tanks: 215 L for a bathtub, 105 L for a shower, 47 L for a sink, and 24 L for a wash basin.
Each of the 4 tanks is equipped with the same monitoring system as detailed below.
Energy study
- 3 x PICOMAG IO-Link flowmeters (1 x hot water input + 1 x cold water input + 1 x output) enabling the measurement of T°C (to +-0.1°C) and flow (to +-0.01l/mn)
- 2 x Input analogue solenoid valves (1x hot water input + 1 x cold water input) Bürkert 3280/3285 allowing the control of the opening as a percentage (to +-1%). This system permits the reproduction of the manual opening of a tap by fine control.
- 2 x PT100 RS Pro 4 wire sensors to measure temperature in HIGH and LOW tank locations
Monitoring
- Monitoring control station with automatic collection of data on disk: second-by-second data historization
- Historization up to 30ms on demand for a given time
Security
- 1x lfm UGB/UGB ultrasonic sensors enabling the measurement of water level, reverse calibrated to define the water level as a %
- 1x Manual output valves
- 1x Electronic output control AON (All Or Nothing) solenoid valve
Demonstrator
The PACMAQ platform serves as a demonstrator for domestic use on a 1:1 scale, with the goal of achieving optimization based on behaviors. This demonstrator can be used for teaching, research and scientific popularization purposes.
The equipment described above enables us to define a certain number of functions and use scenarios. A touch-screen Human-Machine Interface was specially implemented to facilitate control and automation of tests using different modes that can be mixed at leisure:
- Flow control
- Volume control
- Temperature control
In addition, there are a number of functions developed to facilitate the work of users:
- File writing (data acquisition)
- Output and drainage solenoid valve control
- Graph display
- Hardware control functions (acquisition push buttons)
- Historization, etc.
