Design a Fan Coil System for the Energy Systems Laboratory

Job ID: 38178722

Budget: $10 – $30 USD

We seek an HVAC or thermal design engineer to design an air conditioning system based on fan-coil technology for an energy systems laboratory. The design must meet thermal comfort standards according to ASHRAE 55 for summer conditions.
Project Details:

Objective:

Design a fan coil air conditioning system that ensures thermal comfort according to ASHRAE 55 standards.

Scope of Work:

Design Requirements:

- Determine the number of air vents and their positions.
- Calculate the air flow rate, temperature, and humidity level from the vents.
- Define the required water mass flow rate and temperature into the fan coils.
- Design the heat exchanger (liquid-to-moist air) for the fan coil system.

Boundary Conditions:

- The outer wall is exposed to solar radiation with an outside air temperature of 32°C.
- The room floor is partially subjected to solar radiation.
- All other walls are considered adiabatic.

Methodology:

- Conduct basic thermodynamic and thermal analysis to estimate the number of vents, air flow rate, and temperature.
- Perform a detailed analysis using Ansys Icepack to refine temperature and flow conditions.
- Adjust design parameters if thermal comfort conditions are not met.
- Build a Simscape model of the room and fan coil system to finalize the heat exchanger design.

Deliverables:

- Detailed report on the number of air vents, their positions, and specifications.
- Ansys Icepack simulation results and analysis.
- Simscape model of the room and fan coil system.
- Final design of the heat exchanger with necessary calculations and specifications.

Skills Required:

- Proficiency in HVAC design and thermodynamics.
- Experience with Ansys Icepack for thermal analysis.
- Proficiency in MATLAB Simscape for system modeling.
- Knowledge of ASHRAE standards for thermal comfort.

Additional Information:

- The laboratory's orientation is provided in the attached presentation.
- Detailed parameters affecting human thermal comfort and relevant sources are included for reference.
