What is a dehumidifier?

Dehumidification systems are devices that take out extra moisture from the air. What is a dehumidifier exactly, and how does it works? Simply put, it sucks wet air in through a fan and directs it over a refrigerated coil. The airborne moisture condenses at this coil and gathers in a water tank or drain. To perform best, we must make a proper dehumidifier selection using a capacity chart or sizing calculation.

Humidity remover machines are available in different shapes and sizes. Portable units are simple to move from one room to another. On the other hand, a whole-house system may be linked with your HVAC system. But how do you pick the ideal air dehumidifier for your particular environment when so many options exist?

Why need correct dehumidifier selection?

It is imperative to choose the appropriate dehumidifier for your area. The wrong dehumidifier size or type might result in underperformance. But more than that, it will waste energy and even can cause property damage. It is very important to do proper dehumidifier calculations before buying the unit.

For example, a lower-capacity moisture absorber might fail to remove total moisture from the space. It will run continuously without cut-off, and hence it might fail. Similarly, a high-capacity dehumidifier machine can waste energy and overdry the room. At the same time, you will pay a high amount to buy large rating models. 

It is crucial to consider various variables to make sure that you select the ideal dehumidifier. For example, for the dehumidifier sizing for a room, you should consider room size, present humidity level, required humidity level, and room temperature. Every site condition is going to be different than others. Hence, we must conduct a proper site study to collect all parameters for the appropriate dehumidifier capacity selection.

Fortunately, a dehumidifier selection chart is the right tool to help you. It can guide you in picking the best dehumidification system for your application by keeping in mind variables. We need to consider other aspects like noise level, energy efficiency, and ease of maintenance. 

Factors affecting dehumidifier capacity chart.

After understanding the types of dehumidifiers and their pros and cons, it is time to understand factors that can affect the selection process. The volume of the space that needs to dry is the most crucial factor. Dehumidifier sizing should be done in such a way that it should be capable of the whole area without overload. The underrated unit will only remove the moisture partially from the room, and the overrated one will cost more to your client. 

The required humidity level is also going to affect the dehumidifier calculation. Indeed, we need more capacity the achieve lower moisture levels and vice versa. Every application has different requirements for climate conditions. We also need to choose the right dehumidification system based on the humidity that needs to achieve. For example, a refrigerant unit can be the wrong choice to accomplish arid conditions. At the same time, a desiccant machine can work perfectly fine. 

Every dehumidifier sizing guide considers the room temperature as the major factor when selecting a dehumidification system. Since the refrigerant unit uses condensation to remove moisture, the air temperature affects its capacity. If you use compressor units inside very cold spaces, then ice very formed on its coils, and it will not able to condense humidity. But, in contrast, desiccant dryers work better in colder places. So, while doing dehumidifier calculations, it is crucial to consider room temperature.

If you buy a dehumidifier for your home, industry, or indoor swimming pool, please invest some time to choose the right one. Other features we should consider while selecting a unit are its noise level & energy consumption. Ease of maintenance and availability of spare parts is another must-to-know decision-making point. The end user should always do some research before buying the machine. They should refer to a reliable dehumidifier selection guide or hire a consultant.

Understanding Humidity.

In simple words, humidity is the amount of water vapor in the air. It can affect our health and the comfort of the occupant. And most importantly, it ill affects the quality of the air we breathe. Mold, mildew, & other dangerous pathogens can grow in a humid environment. These pathogens can aggravate to allergies and respiratory disorders. Conversely, low moisture can result in dry skin, sinuses, and other health problems. Also, high moisture conditions in industrial manufacturing plants can compromise the quality of goods produced. The proper dehumidifier selection guide can avoid the effect of dampness.

Our necessity to breathe clean air, as well as our general health and comfort, are all impacted by humidity. Proper breathing is an important aspect. Maintaining the best indoor air quality requires an understanding of humidity. We need to understand how moisture affects our indoor environments. Here we will discuss how it is measured and interpreted. We also will see the appropriate humidity ranges for various sorts of applications. 

Measuring & interpreting humidity.

Maintaining ideal indoor air quality requires measuring and interpreting humidity levels correctly. A hygrometer is made expressly to measure the amount of water vapor in the air. It is the most popular technique to measure humidity. Hygrometers can be found in many configurations. These gadgets use sensors to monitor the moisture content. It processes data from the sensors and then gives humidity level readings.

The optimal humidity level for indoor spaces ranges from 30% to 60%. The optimal range, however, can change based on several variables. Consider the local climate and the type of environment while selecting a suitable moisture range. Some people might like a higher humidity level in their home office or bedroom. In contrast, others would prefer a lower one. In short, the site condition and location play an important room while deciding suitable moisture levels. Here a dehumidifier capacity chart can be used to select the right unit for controlling moisture.

With the variety of variables that can affect the accuracy of the data, interpreting humidity levels can be a little challenging. For instance, the temperature of the space and the presence of other things in the air can affect humidity levels. It’s also important to note that humidity levels can fluctuate throughout the day. So it’s essential to monitor levels over time to get an accurate reading.

Recommended humidity levels.

The ideal humidity levels for different spaces can vary depending on several factors such as climate, space size, and the activities that take place. The ideal range for indoor humidity levels is between 30% and 60%. However, specific guidelines can be followed to determine the ideal humidity level for different spaces. A dehumidification system with the right dehumidifier capacity selection can achieve the desired conditions.

As we discussed before, too wet or too dry air can give adverse effects on our health. The suitable humidity level in a bedroom or living room is typically between 40% and 50%. This range ensures optimal comfort and the prevention of mold growth. The best moisture condition in a home office or library is slightly higher. It is recommended around 45% to 55%. This higher level can help prevent damage to books.

Keeping a reduced humidity level in a kitchen or bathroom is crucial. As we know, damp places are conducive to the growth of mold and germs. Because at these places, most of the moisture gets generated due to water work. The recommended humidity level for the kitchen and bathroom is between 30% and 50% RH.

Due to less air ventilation, the basement constantly struggles with a humid environment. Thus, we need to take extra care in the basement to control humidity and stop mold and fungus. A dehumidification could be required to keep a basement’s humidity levels at their ideal levels in very humid climates. An ideal basement humidity should be 50% or less. Generally, a number of factors might affect what humidity level is best for that place. Following general guidelines and monitoring moisture levels can improve indoor air quality.

Types of Dehumidifiers.

Dehumidifier is an essential device for maintaining optimal indoor air quality. Creating a dry climate can prevent the growth of harmful pathogens like mold and mildew. However, selecting the right type and capacity using a dehumidifier size chart is very important. Many options are available in the market. Choosing the right unit is a difficult & time-consuming exercise. 

Let’s discuss different types of dehumidifiers and their sizing. Also, we will discuss their unique features and benefits over the other types. Before buying a dryer, selecting the correct type of unit that will suit your application and budget is crucial. For example, if your application area has a low temperature, then you need to select a desiccant unit over a compressor-based unit. Similarly, a wall mount or ceiling mount unit is more ideal for space constraint areas than a portable system.

Based on the working principle, there are majorly two types of systems. The most popular desiccant and refrigerant type dehumidifiers. Always refer to the dehumidifier selection chart for the suitable capacity.

Compressor dehumidifier.

It is the most commonly used dehumidification system. This system type is also called a compressor or condensation dehumidifier. When humid air is drawn in and passed over a cooled coil, the moisture in the air condenses. Then the condensate water gets collected in a detachable water tank. These types of systems are frequently portable and of small capacity. It is perfect for smaller bedrooms or offices. They might not be as effective in locations with high humidity or extremely low temperatures.

Pros and cons of refrigerant dehumidifiers.

Refrigerant or condensation dehumidifiers are the most widely used and offer the highest moisture removal capacity. However, they can be noisy and require a constant power source. It is the most affordable dehumidification system. And with the help of a dehumidifier selection chart, the user can choose its capacity. But the main drawback of compressor dehumidifiers is that they cannot use to dehumidify low-temperature spaces. At the same time, it can not achieve a very low humidity level.

Absorption dehumidifiers.

Desiccant dehumidifiers also know as absorption dryers. It uses a chemical drying agent such as silica to absorb moisture from the air. These units are often quieter and more energy-efficient than refrigerant models, making them a popular choice for bedrooms or living rooms. A silica gel dehumidification system’s major advantage is that it can dry in colder places such as cold storage rooms. However, they typically have a smaller capacity and may require more frequent maintenance than refrigerant models.

Pros & cons of desiccant dehumidifiers.

Absorption dryers can achieve humidity as low as 10% RH. Since its working principle is not condensation, it can use effectively at low temperatures. The dehumidifier capacity chart of this system is totally different than traditional units. Desiccant dehumidifiers are quieter and more energy-efficient than refrigerant models. However, they typically have a smaller capacity and require more frequent maintenance than refrigerant models. They also tend to be more expensive than comparable refrigerant models.
