Updated 2019 - Greetings once again and welcome to this review of the Best Evaporative Coolers which are available from the US market at present. As summer is around the corner, it's time to get ready cooling appliances for your houses and offices. Evaporative cooling technology is most efficient in dry and hot regions. An Evaporative cooler is an appliance that cools air by the evaporation of water and they are completely different as compare to air conditioning system that use refrigeration cycles. The temperature of dry air will be dropped considerably through the physical change of liquid water to vapor (evaporation). This will cool air using less energy than refrigeration.
In very dry climates, phase change cooling of air has the additional benefit of acquisition the air with a lot of wet for the comfort of building occupants. The cooling potential for phase change cooling relies on the wet-bulb depression, the distinction between dry-bulb temperature and wet-bulb temperature. In arid climates, phase change cooling will scale back energy consumption and total instrumentality for acquisition as an alternate to compressor-based cooling. In climates not thought of arid, indirect phase change cooling will still cash in of the phase change cooling method while not increasing wetness. Passive phase change cooling methods supply constant edges of mechanical phase change cooling systems while not the quality of apparatus and ductwork. There are many evaporative coolers commercially available in the market with different capacity and ranges depending on the need of the customer.
Points to consider before you buy an Evaporative Cooler:
It's really important to keep your indoor environment cool and comfortable in the summer while keeping electric utility bills in control. Evaporative coolers offer an eco-friendly, healthy, and cost-effective substitute to conventional air conditioning systems.
- Know your Climate first: Evaporative cooling is a simple and an excellent way for controlling temperature of your home and offices. However, depending on the climate where you live, evaporative cooling might not be the best for you. So you have to understand how evaporative coolers work will facilitate you make a decision if this is the correct cooling solution for your place. The important point while using the evaporative cooler is the hot dry air, coolers are most useful and effective in the hottest times of the day and below 50% humidity levels. Evaporative coolers work excellent when the relative humidity is around 60%, although they work fine in all humid conditions when use in outdoor places.
- Evaporative coolers comparison with traditional air conditioning systems: The basic purpose of both devices is the same to provide you a cooled space in hot summer. The biggest difference of evaporative cooler is the price of course, energy efficiency and environmentally friendly than conventional air conditioning systems. Evaporative cooler uses simple technology to cool indoor air while air conditioners machines uses refrigerated cooling systems. It is well noticed that they are three times cheaper than air conditioners systems cost in terms of installations, water, electricity. Evaporative coolers are environmentally friendly. Furthermore, these work best in the fresh air availability with easy mobility.
- What size Evaporative cooler will be most effective according to space: The key to buy the best evaporative cooler is to know the size of your space where you want to install it, how big it is? An evaporative cooler designed for smaller area can't be efficient if you use it for big size of places. The CFM (Cubic Feet per Minute) is the amount of fresh air cycled through your environment per minute. Following formula is used to find the CFM: Square feet needed to be cooled multiplied by ceiling height (in feet) and divide it by 2. For instance, if your room is 450 square feet with 8-foot ceilings 450 X 8 / 2 = 1,800 CFM. In relation to this equation, you would need a cooler with a CFM of 1,800.
- Different types of coolers: There are different types of coolers are available, you have to see your space which one is fit for your purpose. Normally 2 types of residential evaporative coolers - portable and window mounted. These both types of cooler designed for small to larger scale places but off course cannot cover the entire houses. If you have the need of cooling in outdoor places as gardens then portable coolers are the great for this purpose. For rooms inside the houses, offices window types of coolers best as these work replacement of windows air conditioners. Installations of these types are very easy and less time consuming, you can install vertical or horizontally as per the need of situation of your room.
- Maintenance required for an evaporative cooler: Either you want to have window or portable evaporative cooler, the proper maintenance of the devices is necessary from time to time. The basic cleanings of the appliances make their performance great and increase its life. You have to clean the filters and water pads once every two weeks with warm water and detergent to remove dust, dirt. The portable coolers need cleanings at regular intervals with cloth. For window evaporative coolers change the moisture pads, clean the pump, oil the motor if needed.
- Health Hazards: Number of authorities raised the issue that an improperly maintained cooler could be a threat to the public health as mosquito breeding could be possible in the water tank area of the cooler.
Frequently Asked Questions about Evaporative Coolers
Q: How does an evaporative cooler actually work to cool a small house?
A: Water pump circulates the water from the water tank on the water pads or cooling media which becomes wet, A fan draws the outside air to move through the cooling pads and it cools by evaporations. To get the most efficient cooling it is necessary to saturate the cooling pads all the times.
Q: Can ice improve the cooling process?
A: No, if you put ice in the water tank area of the cooler, it will not improve the cooling efficiency. Tap water will provide the same results as crushed ice or refrigerated water. So you can use normal water.
Q: How can you improve the performance of an evaporative cooler?
A: It is strongly recommended that Evaporative cooler must not be used in enclosed places, one of the window or door must be opened to free air flow, so make sure a cross ventilation to improve the efficiency of cooling of your room.
Q: Does evaporative cooler increase humidity and produce condensation in the room?
A: No, it does not increase the humidity as these are designed on balanced ventilation scheme; you have just keep open one of the door or window open while cooler is running.
Q: Why the evaporative coolers drain some water?
A: It means your evaporative cooler is working perfectly fine. The water management system of your cooler is excellent, as these are designed to monitor and control the water in the water tank. Because cooler drains the water only when its needed to.
