​Temperature Perception & Energy Saving

The Silent Cicada Personal Air Conditioner operates on several key cooling principles designed to enhance personal comfort without altering the body's core temperature significantly:

  1. Enhanced cooling sensation: Aligning with the body's thermoregulation, Silent Cicada targets thermoreceptor-rich areas such as the wrists for precise cooling. It focuses on enhancing the cooling sensation rather than reducing the core temperature, adhering to the body's natural temperature control mechanisms.

  2. Heat Relief Activation: By stimulating natural heat relief processes and arteriovenous anastomoses (AVAs) in areas prone to efficient cooling like palms and wrists, and integrating Traditional Chinese Medicine practices by activating the "Waiguan" acupuncture point, the device efficiently dissipates heat.

In essence, the Silent Cicada Personal Air Conditioner provides a nuanced and scientifically informed approach to personal cooling, prioritizing safety, effectiveness, and the enhancement of the body's natural cooling responses.

Silent Cicada alters temperature perception

We conducted a perception of ambient temperature blind test with Silent Cicada personal air conditioner, finding that Silent Cicada personal air conditioner significantly altered temperature perception, especially in warmer settings. Additionally, older participants noticed more pronounced temperature changes than younger ones. 

Test targets: 20 Volunteers, Ages 18-40; and 20 Volunteers, Ages 41-63.

Blind testing with functional (FD) and non-functional devices (NFD).

Participants estimated room temperature after 5 minutes, then switched devices and repeated.

Findings:

The experiment demonstrates that the Silent Cicada personal air conditioner effectively reduces the perceived temperature for users, with the sensation of cooling being more pronounced in older adults. The increasing perception of coolness with higher ambient temperatures underscores the device's utility in effectively mitigating discomfort during hotter conditions, showcasing its potential as a versatile and valuable tool for personal climate control across age groups.

Another experiment assessed the effectiveness of the Silent Cicada personal air conditioner, in conjunction with a normal desk fan, on thermal comfort in an office setting, using a survey informed by Berkeley's format. The study involved 24 volunteers aged 18 to 63, evenly split by gender, comparing two settings: one with only the standard air conditioning set at 26°C, and another with personal air conditioners plus a desk fan, aimed at enhancing air movement. 

​

The results demonstrated that introducing the Silent Cicada personal air conditioner and desk fan markedly increased thermal comfort, satisfaction, and levels of alertness and concentration, while maintaining the same air freshness. This indicates that personalized cooling, combined with increased air circulation, significantly boosts thermal comfort and overall productivity in the workplace. A significant majority (58%) of participants favored the conditions provided by the personal air conditioner and fan at a set temperature of 28°C over the standard air-conditioned environment at 26°C.

Notably, female participants reported greater thermal comfort and satisfaction, suggesting gender-related differences in thermal preference and satisfaction.

 

The findings reveal that integrating Silent Cicada personal air conditioners with desk fans not only significantly improves thermal comfort and satisfaction in office settings but also offers the potential for considerable energy savings and environmental benefits. This is achieved by allowing higher indoor temperature settings without compromising on comfort.

With Silent Cicada and a desk fan, users can comfortably increase their AC's set temperature

By integrating our Silent Cicada Personal Air Conditioner and a desk fan, users can comfortably increase their AC's set temperature while maintaining a cool sensation, since raising the set temperature of an air conditioner by just 1 degree can significantly reduce energy consumption, with savings ranging from 6% to 8% per degree.

Suppose Mr. Tan owns a traditional 1000W air conditioner. By using our product, he can reduce his air conditioner's operating time by 6.5 hours daily and increase the set temperature by 2 degrees. This adjustment results in daily energy savings of 6.43 kWh. With Singapore's electricity cost at 32.58 cents/kWh, Mr. Tan will save S$2.10 daily!

The average carbon intensity of the electricity in Singapore is 0.4 kgCO2/kWh (it might vary significantly across different regions). Mr. Tan would reduce carbon emissions by approximately 2.57 kilograms per day!

With Silent Cicada, you may set your air con to a higher temperature without compromising on comfort

This approach conserves energy and lowers carbon emissions, supporting eco-friendly initiatives. And it also offers to our customers, cost saving!
