Residential E-Air Conditioners


            No doubts our evaporative cooler technology is the Next generation cooling machines alternative for market available conventional air conditioners in almost all areas (except coastal areas where humidity is always more than 70%). Almost 80% of the homes can be possible to convert by this concept. We can save 70% less power than conventional Air conditioners. For example 1000 Sq.ft home can be cooled with our 400 W powered coolers. But Air Conditioner means 1.5 tons X 2 nos required for same area, which consumes 1700W X 2 = 3400W power. Compare this data for power saving. As well as electricity bill up to 10 times more.


Thumba E-Air Conditioners For Residency Conventional Air Conditioners
1. Works with water evaporation Technology which is environment friendly. Works with chemical Refrigerants which is very harmful to environment.
2. Very less power consumption 200 W for 600 Sq. Feet area. Much more power consumption 750 W (Inverter Type) to 1600W (Non Inverter Type) for 200 sq. feet area.
3. It increases humidity above 65%. Always keep you fresh and active. It absorbs inside room humidity which reduces it up to 25% causing skin dryness.
4. Always fresh cooling air replaces existing indoor hot air. Almost same indoor air recirculation which causing more CO2 possibility room inside .
5. Works with normal home inverter from 0.5KW with single battery (45Ah to 200Ah). Not possible to run with normal inverter. It needs 5KVA inverter for normal AC and 3KVA for inverter AC. For this we need minimum 4 numbers of 150 Ah battery setup.
6. No need for fully insulated rooms. It must be partial open on top side to push out hot air. It needs insulated room to avoid cooled air losses. Otherwise you never get cooling effect.
7. No chances for over cooling issues. It never cool below 24 Degree C. but it increase humidity upto 85% to cool indoors. Over cooling may create health issues for example 17 Degree C to 20 Degree C is not suitable for our health.

Humidity Means Water content present air inside room

Before discussing this matter we must know about basic working principles of common cooling technologies.

In Air conditioners room inside temperature cooled by evaporation of refrigerants like Freon, Ammonia gases. These gases compressed to high pressure and emits by a orifice (or) nozzles or capillary tubes into sudden low pressure to reduce much more temperature (upto -31 degree C) and passes through evaporator coil and fan assembly to cool rooms. Here temperature suddenly reduced and more chance to condense water present in room air converted water vapours into pure water. You can see separate water line in air conditioners for drain it out which leads to more dry air in room inside than outsides. You can feel the dryness in skin , nose during log breath. No way we must face this type of health issues in Air conditioners. Commonly people always consider or like about favourable temperature in between 17 degree C to 24 degree C only. They never consider about relative humidity essentials. For your better health temperature range is 26 degree C to 30 Degree C and relative humidity is 60% to 85%.

Another problem in Air conditioner is same air circulated repeatedly to avoid cooling losses. This is also increase the Carbon di Oxide than permitted levels leads to lung issues due to poisonous CO2.

Everybody knows during COVID-19 pandemic days all Air conditioners must be stopped. Reason is virus, Bacteria and fungus growth extremely increases due to low temperature (below 24 degree C). But in normal room temperature their growth is considerably less than AC environments we must maintain room temperatures more than 26 degree C to germs growth.

The refrigerants used in fridge chillers, air conditioners made a huge damage in our atmospheric Ozon (O3 Layer since last 35 years, f12, f22 are the most popular refrigerant in this list. Due to strict laws by global council recently we change into F-134A and some other Ozon friendly gases for cooling appliances. But already we have damaged more. So we must make new technologies instead of refrigerant base appliances.
