How to Check For Their Energy Efficiency and Cost of Operations?

Dehumidifiers can be found in two major types, industrial/commercial and residential type of dehumidifiers;

Residential Dehumidifiers

Residential dehumidifiers are usually portable and self-contained equipment which reduce humidity level in small and large indoor areas. Such models are available in large, medium and small moisture capacities and typically have a lot of convenient features which we merely use for day to day need.

When you buy a dehumidifier, you might observe that most of the residential dehumidifiers include an electronic control panel, casters, multiple fan speeds, water buckets, onboard humidistats, and some also have energy star ratings.

These are just a few of the most common features that are found in the residential models. Most if not all residential dehumidifiers work well for daily dehumidifying needs around homes and some can also be effective when used for larger spaces like basements and crawlways.

Whole House Dehumidifiers

Whole house dehumidifier options are in the middle of a residential and commercial humidifier because it can keep a whole house, building and sometimes even for small to medium work setups dry and comfortable. A ducted whole house unit installs straight into your HVAC system to dehumidify air as it is cooled. Cool and dry air is distributed across all rooms via ductwork. Such models are best if you need to dehumidify houses over 1,500 sq.ft. It is generally best to have whole house dehumidifiers installed by a professional HVAC service provider.

There is also some stand along whole house units that are portable yet big enough to reduce whole humidity floor. Just like portable units, these are plug and play. However, it is far more important to place them in a centralized place to get most effective dehumidification.

Industrial/Commercial dehumidifiers

Industrial also is known as commercial dehumidifiers are heavy duty and larger units that are designed in a way that they can cope with more challenging dehumidifying tasks. Such types of models usually have moisture removal capabilities that are much larger as compared to the residential or whole house dehumidifiers units, and they are well suited to the houses that are constructed with much rugged and the all-weather materials in order to withstand the severe conditions.

Energy Efficiency and Cost of Operation of Dehumidifiers and how fan help in it?

Nowadays dehumidifiers are now built with more efficient fans and compressors, and Energy Star Ratings certify therefore many of them. There are two efficiency indicators you must evaluate when buying energy efficient dehumidifiers.

Energy Star Rating

Energy Star qualified Dehumidifiers have been tested and evaluated to energy rigorous efficiency standards. They remove the same amount of moisture as similarly sized conventional units, however by consuming 15 percent less energy. They are also constructed with energy efficient compressors, fans and refrigeration coils to help use lesser power and removing maximum moisture possible.

Energy Factor

The energy factor is efficiency determined by a number of liters removed per kW of electricity i.e., L/kWh. The higher is the energy factor more energy efficient will dehumidifier is.

Operational Costs Estimation

To estimate running cost can help to calculate hourly, daily, and even monthly cost of operation to see if things are in your budget or not. You can do this by determining kWh used. The formula is easy, multiply the unit’s wattage by the number of hours used per day and divide it with 1,000. The result will show daily kWh consumption. Multiply this figure by electricity rate, and you will get operating cost per day. Do simple math to calculate hourly further, monthly, annually or any periodical costs.

How Fan Operation Helps In Energy Efficiency

Some dehumidifiers include fans which run consistently or just when the system is actively dehumidifying. In the past, a heated debate was on which fan designs fuels more efficient system, here is a detail on each.

Fan Runs Continuously

When the fan runs consistently, it is always on whether the compressor is working or not. Manufacturers theorize that continuously running fan can help to move air continuously past sensor, so that dehumidifier gauges more precise humidity level. By this dehumidifier adjust fan speed to maintain the desired level of humidity consistently. Moreover, continuously moving fan redistribute dehumidified air effectively across the room and give even coverage. Some individuals might be worried about the amount of energy used by running such a fan. However, this should not be a concern as fan consumes just an amount used by a light bulb.

Fan Runs Only While Dehumidifying

When fan only run while dehumidifying, it cycles off while compressor turns off. It cycles immediately with the compressor or few minutes after it shuts off. Manufacturers theorize that continually moving fan saves energy to help dehumidifier work more efficiently. However again, energy savings are minimal as a fan aren’t considered unnecessary energy consumers.

Many other features of commercial or industrial dehumidifiers include internal condensate pumps, low-temperature operations, power failure protection, and other simplified controls. An industrial dehumidifier is also helpful in flood-damaged areas, indoor pools and the like.
