Desert cooler; its advantages and benefits

Desert cooler; its advantages and benefits

Desert cooler works on evaporation principle and hence it also called as evaporative desert air cooler or outdoor cooler. To give brief understanding of system, it consist of fan motor, water pump, evaporative pad and body of unit. Evaporation pad fixed on back or/and sides of units. Fan motor mounted in middle in a such way that it will suck air through pad and through it from front side of unit. At bottom a water tank is designed in which submersible pump is placed. This cooler pump push water at top of unit and designed made in such way that this water poured at top surface of pad which in turn make pad wet.  Since cooler pump is continuous in operation, hence pad will remain wet all the time. When user starts cooler, fan will suck air through wet pad and hence as per evaporation principle temperature of air goes down and becomes cold. this cold air through out.  Now there are certain advantages of these Evaporation desert cooler.


Advantages of Desert Air cooler working on evaporation principle.

There are many advantages of these outdoor cooler but 7 advantages are major which we are going to discuss as follow:

  • VT-1c Desert cooler for oudoor use works on evaporative principleLow initial cost: Cost of desert air cooler is much less than cost of air conditioner of equivalent air flow. Due to low initial cost it is affordable masses and hence country like India and China evaporative air cooler are very popular. Also due to its low cost many large factories and production centers prefers these unit of avoid large CAPEX.
  • Electricity Saving:  An air cooler consumes only 1/4th of electric power than that of air conditioner of equivalent air flow. Hence certainly for large space it is always recommended to go or evaporation desert cooling to save electricity and hence running cost.
  • Environmental Friendly: These outdoor air cooler only uses water as ingredient. There is no use of Freon gases or chemical coolant which use in air conditioner.  Also as explain above industrial desert cooler consumes very low electricity hence these cooler are more environmental friendly than air conditioner.
  • Healthy preposition: As explain working in first paragraph, desert air cooler takes fresh air from backside and through it to space and this air now exhaust out. Hence at every time outdoor air cooler brings fresh air in room. However in case of air conditioner same air is recirculated.
  • Work as Humidifier: Since outdoor air cooler work on evaporation principle, when fresh air passes through wet pad it becomes cold and humid. Hence air coming out from air cooler will have humidity and which help to increase humidity in room and help to reduce respiratory problem and skin issues due to dryness.
  • Plug and Play Device: Installation of these coolers are very easy. Just need to put water and connect to power and start unit. Units are very much very easily movable. From control panel of evaporative air coolers user can adjust fan speed at low, medium or high. Pump and can be switch off and unit can be use as simple FAN also.
  • Low Maintenance: The coolers virtually do not need any regular maintenance as such. You need to fill water tank once and then it works at its own. If user wants to avoid refilling of tank manually then there is provision for connecting water supply pipe directly to unit since unit has floating valve built in which will cut water supply when tank gets full.

Basic principle of this outdoor cooler is as follows: water evaporation drives away the surrounding heat and causes the temperature to cool down.

Its working principle is that negative pressure occurs because of wind draining by exhaust fan: air goes through wet congruent cooling pad and the motor pump continuously transports water to the pipes and cooling pad at the same time.

Air cooler is a product made in accordance with European high technology. The basic theory for reducing heat is water evaporation; carry all the heat of the surrounding area and it reduces the air’s temperature.

The water continuously wetting the cooling pad surface evenly and the wet cooling pad angle makes the water current flow to the side od wind inlet, cooling pad angle makes the water current flow to the side of wind inlet, absorbing a certain amount of heat from the air, which cools down upon contact with the cooling pad.

The wet cooling pad also makes the wind cool and fresh. The circulating water falls to the bottom, forming the water cycle. There is a water level indicator at the panel. So when the water level indicator reaches the bottom level, the inlet valve will open automatically to add water; when the water reaches the indicated full leve, the valve will close automatically.
