In summary, at a constant pressure of 100 kPa, a dehumidifier is removing moisture from moist air at a rate of 300 m3/min and exiting at 10°C. The mass flow rate of dry air is 311.61 kg/min, the water removal rate is 11.40 kg/min, and the required refrigeration capacity is -181.91 tons. This problem may require knowledge beyond what has been taught by the professor and may require additional research and understanding of the topic.

Homework Statement



Moist air at 40 C and 90% R.H. enters a dehumidifyer at the rate of 300 m3/min. The condensate and the saturated air exit at 10oC through separate exits. The pressure remains constant at 100 kPa. Determine (a) the mass flow rate of dry air, (b) the water removal rate, and (c) the required refrigeration capacity in tons.

Answers: (a) 311.61 kg/min, (b) 11.40 kg/min, (c) -181.91 tons

I tried everything I know in my scratch but this topic does not teach by my professor. I read some books and research. However, I still do not get the answer. Just explain to me how to solve this kind of problems

FAQ: How to Calculate Moist Air Dehumidification and Cooling Rates?

What is the purpose of cooling and dehumidifying?

The purpose of cooling and dehumidifying is to remove excess heat and moisture from a space in order to create a more comfortable and healthy environment.

How does cooling and dehumidifying work?

Cooling and dehumidifying work by using a combination of refrigeration and air circulation. The process involves removing warm and humid air from a space, passing it over a cold coil to condense the moisture, and then returning the cooled and dehumidified air back into the space.

What are the benefits of cooling and dehumidifying?

There are several benefits to cooling and dehumidifying, including improved air quality, reduced risk of mold and mildew growth, and increased comfort levels. It can also help to lower energy costs by making it easier for your air conditioning system to maintain a consistent temperature.

How does cooling and dehumidifying impact energy consumption?

While cooling and dehumidifying does require energy to operate, it can actually help to reduce overall energy consumption. By removing excess humidity from the air, your air conditioning system doesn't have to work as hard to cool the space, resulting in lower energy usage and costs.

How often should cooling and dehumidifying be done?

The frequency of cooling and dehumidifying depends on several factors, such as the climate, size of the space, and level of humidity. In general, it is recommended to run your air conditioning system for a few hours each day to maintain optimal humidity levels and air quality.
