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 remove excess moisture from a room, but does a dehumidifier cool a room? We explore the answer here.

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.
