Chillers are the only way of beating the heat, when summers are near. The increased level of humidity in the air often makes people sweat profusely and serves as a breeding ground for bacteria and parasites. The humid air circulating indoors may aggravate sickness and allergic conditions, leaving the atmosphere unhygienic. Dehumidifier’s purify air indoors, rendering it fresh and safe to breathe in. Created for industrial purposes, these dry air Dehumidifiers are now progressively used in every new business set-up and household.
Chillers are basically a closed system, which utilizes the process of evaporation and condensation to cool the air in a room. Making use of drying technology, the dry air system cools the temperature by passing on the heat from the source to the evaporator coil. Basically, there are two kinds of chillers. One is air cooled and the other being water cooled. Air cooled chillers, as the name suggests uses air to dehumidify a space, whereas water cooled chillers uses water to cool a place.
There exists no formulae to find the perfect dehumidifier and neither of them would be suitable to every device. Each chiller has its own set of advantages and disadvantages and a buyer should effectively scrutinise them before investing in one. Space is one of the most important factors, when it comes to choosing a Dehumidifier. Air chillers are larger in size and require a large space for installation, whereas water cooled chillers are small, but require cooling towers and a mechanical room for effective functioning. Air cooled chillers would be unfavourable for industries, which have walls higher than the unit. They require continuous flow of fresh air and an obstructed air flow may create problems with recirculation. Water chilled coolers are more suitable, when there’s a lack of space and restricted air flow.
Every chiller produces a noise when it is in use. The noise of air cooled chillers cannot be determined as each fans installed in them would have a different decibel. Although, there are various ways to decrease the noise produced by them, it is always better to invest in a system, which is quieter. Air chillers are normally cheaper compared to the money spent on the maintenance of water chillers. The air coolers require less maintenance and don’t need cooling towers, condenser pumps or a mechanical room to function. However, the life span of air chillers is short and is less efficient compared to water chillers. Water chillers on the other hand, have a greater life span and work efficiently with continuous maintenance. Lifespan and the performance of the chillers depend on the quality of the chiller you choose. Ideally, it is always better to consult your local contractor before purchasing one.
