There appears to be a great deal of confusion available about portable air conditioners and swamp coolers. They are not interchangeable. An ac unit portable unit cools, or types of conditions, the environment by eliminating heat energy. The end result is that the air has much less heat energy, for this reason the whole space is cooled. They accomplish this using a heat pump. Heat pumps could be discovered in all forms of air conditioners, as well as refrigerators.
In a heat pump, a fluid with exclusive properties, termed as a refrigerant, is expanded bit by bit by way of a valve into a low pressure tubing known as the evaporator, or development coil. As it expands, the heat energy in the refrigerant becomes much less concentrated, and it gets very cold. This is the cooling side, in which high temperature from the air passing more than it today is readily absorbed by the chilly copper tubing, which in turn warms the refrigerant as well.
As soon as the refrigerant circulates to the compression coil, or maybe condenser, it’s pumped into a tiny, high stress tubing. All the heat energy being brought from the evaporator coil has become squeezed right into a smaller volume, thus the refrigerant becomes very warm. This’s the hot side. The coil heats up and easily releases the excess heat on the air blowing over this side. In a portable air conditioner, this atmosphere is blown out via the exhaust duct.
Portable air conditioners make use of the heat pump system, and therefore are designed as room air conditioners. In some, the blood flow of refrigerant can be reversed, which results to the heater function present in those models.
In contrast, evaporative air coolers, or maybe swamp coolers, do not remove heat energy away from the air, and thus aren’t air conditioners. The term’ super-fan’ might be used . Swamp coolers cool air by blowing it over a wet wick. Moisture in the wick evaporates, cooling air blown by the fan. So it feels cool before the unit, but nowhere else. No heat is taken off the environment, but moisture is added, hence the home itself contains the same volume of heat energy and isn’t cooled. Swamp coolers can’t warm the atmosphere.
The additional moisture from a swamp cooler can make the room uncomfortably moist, especially where background dampness is already substantial. They are most suitable for dry weather, employed as spot coolers. Swamp coolers look a lttle bit like portable ac units, but don’t have exhaust ducts. Advertisement photos of portable ac’s often leave out the exhaust ducts, likely adding to the confusion.
Contributing to the confusion stands out as the term’ evaporative portable air conditioner’, used by some manufacturers. The name advertises a feature these devices have, that being the evaporation of a tub filled with warm water which condensates during the high temperature pump cycle. The evaporated condensate will be removed with the exhaust air. The objective is removing the necessity of emptying the drain pan that was such an inconvenience in older models without this performance.
One more confusing expression is the’ ductless portable air conditioner’ one might view advertised. This’s actually a title given to a form of mini split ac which relies on a mobile within unit to home the expansion coil, instead of the typical wall mounted console. It is real they do not have ducts, however, they still must be plugged in to the exterior via a small gap in the structure, for this reason the heat pump tubing and wires can hook up the movable portion to the exterior fan, where the condenser is situated.
