Definitions

  • Patent Application is related to Patent Application 2873/MUM/2015 filed by the same applicant. Some of the contents of this patent application are in reference to aforesaid patent application.
  • the present invention relates to apparels, and more particularly, the intelligent apparels that provides thermal comfort to a person wearing the apparels, irrespective of climatic conditions, and geographic time zones.

  • the invention further relates to a system and method to provide thermal comfort to a person wearing the said apparels.
  • Human body has innate ability to adjust to the changing climate and weather. Human body’s response to change in surrounding temperature is essentially a biological process. The body generates sweating and vasodilatation in a hot environment, or generates shivering, vasoconstriction and hormonal thermogenesis in a cold environment. These responses are generated by hypothalamus, situated in the brain. Hypothalamus acts as a body thermostat by sending signals to muscles, organs, glands and nervous system in response to the messages received from body sensors in the central nervous system. The signals are carried by hormones to help acclimatise to changing climate. However, the human body needs certain time to acclimatise to weather, if it has to act on its own.
  • thermostat and air conditioning unit Thermostats regulate the flow of heat transfer fluid and maintain the temperature of the desired area at a near constant point, in a given area. If the area to be covered is large, say a commercial premise, it needs large amount of energy for dissipating heat. On an average, the human body needs only 0.03 tonnes of heat dissipation while at rest to 0.12 tonnes of heat dissipation while carrying out heavy work, meaning a lot of energy is wasted while regulating temperature of a large area. Further, each person has different comfort point, depending on his/her body mechanism and health.
  • thermal wear In cooler weather conditions, the option available to an individual is a thermal wear.
  • the thermal wear prevents body heat from escaping to the outer environment, thereby providing warmth to the person wearing it.
  • thermal wear is a passive system and, therefore, is unable to deal with the body sweat.
