The desiccant dehumidification method removes moisture from the air using a filter. In particular, accumulated moisture can be regenerated by drying the filter with hot air, allowing for repeated use without replacement. Unlike air conditioners, this method removes moisture without using a compressor, allowing independent control of humidity regardless of temperature. Therefore, you can precisely manage optimal humidity while maintaining the indoor temperature.

Waste Heat Utilization Desiccant Dehumidification

The dehumidification process based on desiccant absorption technology leverages the high efficiency of the desiccant material, a highly porous substance, which rapidly and effectively adsorbs moisture from the air. In particular, Husheet can be regenerated even at low temperatures below 50°C, which is a big difference from existing materials that require high temperatures above 150°C, and it has been confirmed that there is almost no performance degradation even after more than 100,000 cycles of dehumidification/regeneration. This feature allows the use of abundant waste heat below 50°C, such as air conditioner outdoor unit arrays. When waste heat is utilized, dehumidification is possible without separate energy input, which can significantly improve cooling efficiency.

Clean Cooling

A clean cooling technology, the Humicon provides a more comfortable indoor environment by lowering the humidity instead of temperature. This allows you to maintain comfort by increasing the indoor setting temperature from 24°C to 27°C.

Energy savings: Reduce indoor and outdoor temperature differences to reduce cooling load caused by heat loss by 30% (70% of the total cooling load) and increase cooling efficiency by 20% by increasing air conditioning evaporator temperature by more than 5°C as indoor setting temperature increases and humidity decreases. In addition, ventilation operation increases latent heat recovery efficiency, reducing ventilation load by 40% (20% of the total cooling load).

The formula for reducing cooling energy

Cooling energy

Cooling load / Cooling efficiency

= (1- (0.7 x 0.3 + 0.2 x 0.4)) / (1+0.2) = 0.59  → 41% reduction

41%

Thanks to these innovative technologies, cooling energy is reduced by a whopping 41 percent when applying a humicorn.

In particular, the higher the proportion of latent heat loads,

the greater the savings, which can maximize energy efficiency.

Indoor Environment (OO Girls' Middle School Classroom Lab, August 2020)

If the air conditioner setting temperature is set to 26°C indoors, such as in a classroom, it is difficult to remove moisture, which can lead to excessive humidity increase. However, if you use the humicon with the air conditioner, you can create a pleasant learning environment by properly controlling the humidity

Overview

Humicon was installed on various sites provided by public institutions in Seoul to verify the effect of reducing cooling energy and improving indoor air quality.

Test Site

Seoul Facilities Management Corporation: 4units, Gocheok Sky Dome Office room

Seoul Energy Corporation: 4 units offices/conference rooms/restrooms

SH Corp: 10units, Community facilities

Monitoring period: ‘21.04~’21.11

Empirical results demonstrate the outstanding effectiveness of the Humicon.
