The Importance of Precise Planning
Careful planning of mobile cooling solutions is crucial to reliably meet the desired cooling demand while avoiding unnecessary costs. Incorrect dimensioning can lead to insufficient cooling or excessive energy consumption. Faulty installation or commissioning also carries the risk of system malfunctions and safety defects. Therefore, a precise analysis of the on-site requirements and conditions is essential.
1. Performance: Precisely Determining Cooling Demand
The determination of the required cooling capacity (in kilowatts, kW) is the central point in planning your mobile cooling solution. It depends on various factors and must be carried out precisely to achieve an optimal cooling effect.
Factors for Cooling Capacity Calculation:
- Volume of the room/process to be cooled: The size of the area or medium to be cooled
- Temperature difference: The difference between the current and the desired target temperature
- Heat loads: Internal heat sources (people, machines, lighting) and external heat inputs (solar radiation, ambient temperature)
- Insulation level: The quality of the insulation of the room or containers
- Specific requirements: Special requirements for temperature stability or cooling speed
2. Connection: Integration into Existing Systems
The connection of your mobile cooling solution includes the electrical supply as well as the connection to the refrigerant or water circuit. Both technical feasibility and compliance with safety regulations are of great importance here.
Electrical Connection
Cooling systems are generally high-power consumers and require an appropriate electrical supply. This includes:
- Voltage and frequency: Ensuring compatibility with the existing power supply (e.g., 400V three-phase current)
- Fusing: Sufficient fusing of the circuits to avoid overloads.
- Cable cross-sections: Dimensioning of the cables according to the power consumption and cable length.
Refrigerant or Water Circuit Connection
Mobile chillers or air conditioning units are connected to the circuit to be cooled via flexible hoses. Important aspects are:
- Hose dimensioning: Suitable for the flow rate and pressure of the system to minimize pressure losses
- Tightness: All connections must be absolutely tight to avoid leaks.
- Media: For chillers, the quality of the water (e.g., with antifreeze) must be considered.
3. Commissioning: Starting the Cooling Process
Professional commissioning is crucial for the optimal function and longevity of your mobile cooling solution. It includes several steps that should be carried out by qualified personnel.
Preparation and Testing:
- System check: Verification of all connections for correctness and tightness
- Fill levels: Control of refrigerant or water fill levels
- Electrical check: Measurement of voltages and currents
System Venting
Especially for water-based systems, complete venting of the circuit is essential to avoid air pockets that can reduce performance or cause damage.
Settings and Test Run
- Set parameters: Configuration of the control system according to the desired temperatures and operating conditions
- Test run: Execution of a trial run under real conditions to check the function and make any necessary adjustments
- Monitoring: Observation of system parameters (temperatures, pressures) during operation
Conclusion:
The planning of mobile cooling solutions, the connection, and the commissioning require expertise and precision. A professional approach ensures that your cooling demand is met efficiently, safely, and reliably.
