A new humid air humidifier was designed and built. It is composed with two identical stages. The condensation is achieved on vertical tubes. Many configurations are tested. A thermodynamic model has been established. This model predicted the performances of each stage. The results showed that the flow rate of pure water produced by dehumidification and the exchanged heat power increase with increasing mass flow rates of dry air and cooling water, temperature and absolute humidity of inlet moist air in the dehumidifier. The high quantity of water vapor in air makes a thick film of condensate on cooling tubes. This reduces the flow rate of condensate and thermal power exchanged. So, the use of multistage condenser as dehumidifier is must but not sufficient for optimum efficiency.
Dehumidifiers are an increasingly popular choice, but does a dehumidifier cool a room? Not only can reducing humidity make your room more pleasant, but it can also help protect the people in your home from a host of health issues, including respiratory problems and allergies. Dehumidifiers can also stop the growth of mold, which can be damaging and dangerous to health.
Understanding how dehumidifiers work and what they do can help us answer the question; does a industrial dehumidifier cool a room? While dehumidifiers aren’t designed to reduce a room’s temperature, removing humidity can make it feel cooler and more comfortable. They can even have some surprising benefits, with dehumidifiers helping with snoring and other issues.
Dehumidifiers remove excess moisture in the air by drawing it in from the outside and cooling it. A refrigerant (or compressor) dehumidifier draws in air. This then passes through a cold coil that causes the moisture within the air to condense, becoming water that subsequently drops to a reservoir at the bottom of the machine.
Alternatively, a desiccant dehumidifier uses an absorbent material, such as silica gel or Zeolite, typically formed into a rotor. Air is pushed through the rotor, where the desiccant material removes moisture from the air. While they remove humidity, neither type of dehumidifier won’t noticeably affect the temperature of a room. However, removing humidity may make the room feel cooler.
Dehumidifiers aren’t the same as air conditioning units, which are designed to generate cold air that’s pumped into a room in order to lower the temperature. In contrast, dehumidifiers remove the moisture from the existing air within a space.
Meanwhile, if the humidity level in a room is too low, researchers from Environmental Health Perspectives have established that it can cause a range of health problems, including skin irritation. Meanwhile, scientists from Biological Rhythm Research have also confirmed what most of us already know, that high humidity can also have a "deleterious effect on sleep". High humidity can make a room feel uncomfortable, according to this research from Temperature Medical Physiology and Beyond, as the sweat produced by our bodies to regulate heat doesn’t evaporate as quickly. By removing this humidity, the room can feel cooler and more comfortable. As a result, it's easier to breathe and sleep.
