DEHUMIDIFIER

DEHUMIDIFIER#DEFINING

WORKING PRINCIPLE

MOIST AIR ENTERS DEHUMIDIFIER AND PASSES THROUGH EVAPORATOR COIL

AIR IS DRIED AND CONDENSATION STARTS AT EVAPORATOR COIL

FLOW OF REFRIGERANT THROUGH EVAPORATOR COIL

REFRIGERANT IS COMPRESSED AND HEATED UP AT COMPRESSOR

HOT REFRIGERANT FLOWS TO CONDENSOR COILS AFTER COMPRESSION

DRY AIR PASSES THROUGH CONDENSOR COIL AND GETS WARMED

WARM-DRY AIR IS EXPELLED OUT FROM DEHUMIDIFIER

PROBLEMS#ANALYSING

WEATHER & CLIMATEFor THERMAL COMFORTS

Relative Humidity must be between 30% to 60% during Summer & Winter Season.Above which leads to growth of: Dust mites Bacteria Fungiand, below which occupants might experience: Eye Irritation Stuffy Nose Viral infection growth in body

Temperature must be between 20◦C to 27◦C during winter season and 24◦C to 30◦C during summer season, to avoid any discomfort.

PSYCHO-analysis

With a monsoon where the temperature is around 30°C, the need of the hour in ahousehold is a portable and suitable dehumidifier. But a dehumidifier, which can work asan A.C. in the summer will be a very interesting alternative in the Indian sub-market.The Product should be:1. Area specific2. Portable3. Multifunctional

Metro and coastal cities sincerely needs dehumidifier in the coming years to cope up withthe varying climatic conditions.

ECONOMIC DISTRIBUTIONFor better HUMAN DEVELOPMENT INDEX

Knowing that with unemployment rate of 4.9% last year and a small no. of 5,000 people areescaping from the poverty line each day and wage of small skilled labor is 11,900 INR/Mon.with large variations and high skilled labor is 50,300 INR/Mon. with very less variations.Thus Product manufactured for health benefits and resource preservation has to be madeavailable such that it is accessible to everyone.

PSYCHO-analysis

Since such gap exists between wages between various classes and purchasing power ofand average Indian has been limited to 8,233 INR till the end of 2016.Thus following criteria's have to be fulfilled by dehumidifier:1. Easy to use2. Light on pocket

The dehumidifier introduced in the market has it’s cost till a maximum cost value of 12,000INR to 16,000 INR considering all factors, so as to make it affordable for all Indians withstandard living conditions.
