what is the difference between a condensed and vented tumble dryer?

Answer 1

A condenser collects water in a tank which you have to empty. A vented machine blows the steam out into the air.

Answer 2

A Tumble Dryer (with condenser) needs no outlet to the air to let away the hot air / steam. A Vented Tumble Dryer needs an outlet to the air to let away the hot air / steam. Washer Dryer is a washing machine with a built in Tumble Dryer (either Vented or not)

Answer 3

A condenser type allows the water vapour to condense into water droplets in the machine and you may need to empty a tank at intervals. The vented type requires a hose to be taken to the outside of the house and the vapour is then dispersed into the outside air. The latter requires a hose through a window or a permanent outlet from the machine.

Answer 4

A condenser drier pumps the water (or steam) from inside the machine via the same pipe as when it's emptying during the wash cycle. A vented drier has a long stretchy hose fitted to it which carries the steam to an open window or door etc.

Answer 5

Vented one needs access to the outside to get rid if the moisture. Condensing one will collect the moisture in a container and does not need access to outside.

Answer 6

There are several types of vented dryers. See the information following the infor on vented dryers.

Traditional dryers - Vented dryers

Traditional dryers continuously draw in the cool, dry, ambient air around them and heat it before passing it through the tumbler. Afterwards, the resulting hot, humid air is simply vented outside to make room for more dry air to continue the drying process.

The traditional design makes no effort to recycle the heat put into the load, and so is quite inefficient. Nevertheless, the basic design is simple, reliable, and cheap.



Ventless dryers

Spin dryers
These machines simply spin their drums faster than a typical washer could in order to extract additional water from the load. They may remove more water in two minutes than a heated tumbler dryer can in twenty, thus saving significant amounts of time and energy. Although spinning alone will not completely dry clothing, this additional step saves a worthwhile amount of time and energy for large laundry operations such as those of hospitals or hotels.


Condensation dryers
Just as in a normal dryer, condensation dryers pass heated air through the load. However, instead of exhausting this air, the dryer uses a heat exchanger to cool the air and condense the water vapor into either a drain pipe or a collection tank. Afterwards, this air is run through the loop again. The heat exchanger uses ambient air as its coolant, therefore the heat produced by the dryer will go into the immediate surroundings instead of the outside.

Because the heat exchange process simply cools the Internal air using ambient air, it will not dry the air in the internal loop to as low a level of humidity as the fresh, ambient air. As a consequence of the increased humidity of the air used to dry the load as well as the increased complexity of the design, this type of dryer requires more time and energy than a traditional dryer. However, it is a valid option where long, intricate ducting would be required to vent a traditional dryer.


Heat pump dryers
Whereas condensation dryers use a passive heat exchanger cooled by ambient air, these dryers use a heat pump. The hot, humid air from the tumbler is passed through a heat pump where the cold side condenses the water vapor into either a drain pipe or a collection tank and the hot side reheats the air. In this way not only does the dryer avoid the need for ducting, but it also conserves much of its heat within the dryer instead of exhausting it into the surroundings. Heat pump dryers can therefore use less than half the energy required by either condensation or traditional dryers.

As with condensation dryers, the heat exchanger will not dry the internal air to as low a level of humidity as the ambient air. With respect to ambient air, the higher humidity of the air used to dry the clothes has the effect of increasing drying times; however, because heat pump dryers conserve much of the heat of the air they use, the already-hot air can be cycled more quickly, possibly leading to shorter drying times than traditional dryers, depending on the model.


Mechanical steam compression dryers
A new type of dryer in development, these machines are a more advanced version of heat pump dryers. Instead of using hot air to dry the clothing, mechanical steam compression dryers use water recovered from the clothing in the form of steam. First, the tumbler and its contents are heated to 100 °C. The wet steam that results purges the system of air and is the only remaining atmosphere in the tumbler.

As wet steam exits the tumbler, it is mechanically compressed (hence the name) to extract water vapor and transfer the heat of vaporization to the remaining gaseous steam. This pressurized, gaseous steam is then allowed to expand and is superheated before being injected back into the tumbler where its heat causes more water to vaporize from the clothing, creating more wet steam and restarting the cycle.

Like heat pump dyers, mechanical steam compression dryers recycle much of the heat used to dry the clothes, and they operate in a very similar range of efficiency as heat pump dryers. Both types can be over twice as efficient as traditional dryers. However, the considerably higher temperatures used in mechanical steam compression dryers result in drying times on the order of half as long as those of heat pump dryers.

Answer 7

condenced has a bit that collects the water which you have to empty. this means you can put it anywhere,wheras vented means it has a tube that has to have acsess to outside either thruogh a window or a vent in the wall.
