👉 The house fluid, also known as the house water or indoor humidity, refers to the moisture present within a building's interior environment. It arises from various sources, including evaporation from surfaces like floors and walls, condensation on cold objects, and the release of water vapor from human activities such as breathing, sweating, and cooking. This fluid plays a crucial role in maintaining indoor comfort but can also lead to issues like mold growth, structural damage, and discomfort if not properly managed. Effective humidity control is essential for ensuring a healthy living or working space, balancing moisture levels to prevent these problems.
