What is difference between air cooler and Air conditioners?

When it comes to cooling offices, home  or for that matter big laboratory, installing centralized air conditioner get justified. But installation air conditioner for large production area producing low price product not get justify. In such case we need to install evapoarative air cooler which prove to be more economical than air conditioners. One of major difference between air conditioner and evaporative outdoor cooler is, air conditioner can not cool open space. While evaporative desert cool can give high flow of cold air all around open space which can make occupant comfortable.

Difference between Outdoor coolers and Air conditioners.

There are few major differences between air conditioner and air coolers are as follow:

  1. Initial cost: Air conditioner are much more costlier than desert air coolers. Price of given airflow capacity air cooler, will be at lest 75% less than air conditioner of equivalent airflow capacity.
  2. Electricity: Power consumption of air conditioner is much higher than evaporative outdoor air cooler. Air coolers has capacity to deliver high airflow with low power consumption. For example air cooler with  power consumption of only 1.1kw can delivery cold air flow of around 22000 CMH.
  3. Maintenance cost: Evaporative industrial cooler and maintenance free. While air cooler needs continuous maintenance.
  4. Portability: Evaporative industrial air cooler can be portable in nature. It provides with strong wheels and large water tank. Hence your can actually move your cooling unit from one place to other very easily. But once air conditioner get install at one place then it becomes big procedure to shift at other place.
  5. Economical: Evaporative cooler are more economical in initial and running cost than that of air conditioners.

Five Features of Desert cooler.

  • Large Water Tank & hose pipe connection: Unit should have large water tank to store more water. Water consumption is depend on heat level of air which it going to intake. And places like Dubai and Abu Dhabi in hot summer temperature rise to more than 50 deg C and hence temperature of intake air. So it better to have large water tank. Also it better to have hose connection point with internal floating valve to connect water supply pipe.
  • Low power consuming motor with high airflow: Motor is heart of air cooler. And power efficient motor is in interest of consumer to save running cost but without compromising of air flow. CtrlTech desert air cooler fitted with low power consuming motor with high airflow.
  • Thick evaporative pad: Hot air suck through evaporation pad which kept wet with help of water poured on pad with help of pump. When hot air passed through this wet pad it will loose temperature. And hence more thicker the pad more temperature will loos for hot air and cold air get delivered.
  • Strong lockable wheels: Unit should have first of all very strong wheel since weight of unit will fully filled water tank going to be very high. These wheel should sustain this weight when it stand or when it moves with filled tank. Also these wheels should be lockable.
  • Swing Function: This function allows evaporative air cooler to through air in 180 degree horizontally. Hence we industrial air cooler can cover large space.

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.

Working Principle of VT-1C Desert cooler.

VT-1c Desert cooler for oudoor use works on evaporative principleVT-1c desert cooling unit consist of three major parts; which is fan motor, water pump and cooling pad. Fan motor is responsible to rotate fan to suck air through wet cooling pad and through it front side. Water pump is responsible to pump water on cooling pad continuously so that it will always wet condition. Cooling pad maintain moisture so that when fan sucks air through it, air should be get cooled.

When you start unit, first water pump will start which will pump water from water tank to top of cooling pad. This pumped water discharges at top of pad and hence it make pad wet. Pump continuously pumps water and keep cooling pad wet. After delay of two minutes fan motor will start. This fan motor sucks air through wet cooling pad. When air passes through cooling pad, due to evaporation temperature of air drops and cold air thrown front site.

Water pump transport the water from water tank to the water distribution and cooling pad at the same time. Air goes through the cooling pad, water evaporation dry away the surrounding heat and caused the drop in temperature of air.

Controller controls motor and fan. From controller one can switch on/off air cooler, set speed, switch on/off pump, set timer etc.

how desert cooler workWorking: When you switch on air cooler, fan motor start rotating and so as fan. Fan sucks air from back side which passes through wet pad. As mentioned before pump continually pours water on tope of pad due to which pad get wet and water film get formed at pad. Hot Air passing though wet pad get in touch with water in pad and looses it’s thermal energy instantly which leads to drop in temperature of hot air and cold air get pushed by fan. In many desert cooler design in steady of cooling pad desert cool rediators are get use. To reduce temperature of air from desert cooling system, two pads are get use in some designs which called as Two stage Evaporative cooler.
