Can an Evaporative Air Cooler Be Used in a Café?
The hot days of summer are coming and many are thinking on how to save on electric bills especially those kilowatt-hours that an owner spends in cooling his cafe. During these days of stiff competition and rising cost of energy it is just proper to economize on power usage in order to bring a few more pesos to the bottom line of a cafe’s financial statement.
During the cooler rainy days, using electric to drive the heat away may do. But how about this coming summer, will low-wattage evaporative air coolers do the trick? Above are the pictures of some similar models of evaporative air coolers that are available in the local market but do not take your pick yet. Take time to read what has been written about the product especially about its applicability to Philippine weather conditions. It is also important to call in Advanced Clean Air experts and to get your air conditioner cleaned once in a while for better air quality.
According to Wikipedia, evaporative coolers (also called swamp, desert, or air coolers) are devices that cool air through the simple evaporation of water. They differ from refrigeration or absorption air conditioning, which use vapor-compression or absorption refrigeration cycles. Evaporative cooling is especially well suited for climates where the air is hot and humidity is low. The installation and operating cost of an evaporative air cooler by Whitton Cooling and Heating Green Valley AC repair can be much lower in cost and reasonable too than refrigerative air conditioning, often by as much eighty (80%) or so. The maintenance costs are also low but lights flicker when ac turns on is one of the most common problems with this type of cooling systems.
With the apparent ease of installation (simply by plugging into an electrical outlet), lower first cost than air-conditioning unit and smaller power consumption, a café owner can be easily tempted to buy this equipment; however, the simple truth is that evaporative are coolers are not usable in the Philippines. Specifications by the manufacturers say that evaporative air coolers work best in hot and dry low-humidity areas (around 30% humidity or less), but they also work fairly well in moderate humidity (around 40–50%). Sad to say the Philippine weather during summer months is hot and humid with an average 80% humidity anywhere in the country.
For some feedbacks by those who had tried using evaporative air coolers in the Philippines, please visit a thread entitled Evaporative Air Coolers? Are They OK?.
i think it would work if you can hook it up to the AC.

Its true… I have one. It is negligible difference to having just have an electric fan but an aircon makes a difference. Evaporative is just a waste of money.
Maybe I’m just imagining things but I feel it’s definitely cooler when I switch the cool mode (the mode which the pump trickles out water to wet the pads) of my evaporative cooler. Not as cool as the conventional airconditioner but make things tolerable for me compared to using standard electric fan or switching to plain fan mode of my unit. You must append an effective exhaust system though to counter the evaporative cooling downside which is concentrating too much humidity to a confined space and to maintain it’s effectiveness. The very same reason why evaporative coolers are very effective outdoors and I find that I can reproduce the effect by using the same principle, continuous damp, cool air + good air replacement or circulation.
