Thermal Design

The thermal subsystem is designed to improve indoor thermal comfort by reducing heat gain, increasing airflow, and supporting active cooling when needed. The design focuses on three main strategies: air conditioning, shading, and natural ventilation. These strategies work together to keep the indoor space cooler, reduce energy use, and improve user comfort.

Requirements

The thermal subsystem must meet several requirements related to comfort, safety, cost, and practicality. It needs to reduce indoor heat, improve air circulation, and support the installation of cooling equipment. At the same time, the design must be simple enough to build and must not interfere with the structure or other sub-systems.

Functions

The main function of the thermal subsystem is to control the indoor thermal environment. It should reduce heat gain from sunlight, improve ventilation, and provide cooling when the indoor temperature becomes too high. The system should also help maintain a comfortable and safe environment for users.

Objectives

The main objective of the thermal design is to create a cooler and more comfortable indoor space while using simple and practical design solutions. The design should reduce the need for constant air conditioning by using passive cooling methods such as shading and natural ventilation. It should also be affordable, easy to install, and compatible with the overall project design.

Constraints

The thermal design is limited by the size of the structure, available materials, budget, and safety requirements. The air conditioning unit must be mounted securely without damaging the main structure. Shading components must not block important openings or interfere with other parts of the design. Ventilation openings must allow airflow while still keeping the structure safe and practical.

The Design

Aircon Mounting、

The final thermal design combines active and passive cooling methods. Active cooling is provided by an air conditioning unit, while passive cooling is improved through shading and natural ventilation. This combination helps reduce indoor temperature more effectively and lowers the need for continuous mechanical cooling.

Shading

Shading is used to reduce direct sunlight entering the structure. By blocking part of the solar radiation, the shading system helps reduce indoor heat gain and lowers the cooling load on the air conditioning unit. This passive cooling method does not require electricity and can improve the energy efficiency of the design.

Natural Ventilation

Natural ventilation is included to improve airflow without relying only on mechanical cooling. Openings are placed to allow fresh air to enter and warm air to exit. This helps reduce heat buildup inside the structure and improves air quality for users.

SolidWorks Flow Simulation

SolidWorks Flow Simulation is used to analyze airflow and temperature distribution inside the structure. The simulation helps the team understand how air moves through the interior and where hot air may collect. The results can be used to improve the placement of ventilation openings, shading elements, and the air conditioning unit.
