Dryer vs drying rack | OliNo
Recently, there has to Jeroen's work is a discussion about the energy efficiency of a condensation dryer and drying, the condensation dryer would be more efficient or at least as effective. childrens storage An interesting proposition, that required investigation.
The thesis is based on the following: the clothes drying on a clothes horse in the house withdraws heat by the evaporation of the water, about 1.5 - 2 liters childrens storage per load. This heat you have to get back to the co-firing boiler. If you use a condensing dryer in the house but the heat released childrens storage again used in your home (less heating).
Electric Laundry condensation dryer first ever figured out what was actually condensing dryer. I found a nice explanation and picture on the internet and even slightly increasing. Figure 1: the condensation dryer and its components
First of all, air is heated in the dryer by means of an electric heating childrens storage element. A fan blows the warm air along the (wet) clothes and can record in the clothing itself in the moisture. childrens storage The warm moist air coming from somewhere in the dryer right where it releases childrens storage its heat through a heat exchanger. As the air cools it can not hold as much water vapor and the water vapor condenses as water that is collected in a container. Thereafter, the air is again stripped of water vapor and will be heated again and reused for the next cycle. Thus, there is an air circuit in the dryer which itself repeatedly used for a dry cycle. The heat exchanger takes in ambient childrens storage air, which is cooler childrens storage than the air will have to be used in the condensation tumble dryer itself for the cycle. These ambient air takes the heat from the so-called cycle air over and leaves childrens storage as the warm air condenser childrens storage dryer, therefore there is warm air from the dryer. There is also a motor that rotates the drum where the clothes inside.
If you're nice after drying the collected water that is in the tray, then you are washed away by the water (you let it stand, then this water will eventually evaporate and we still lose energy). Furthermore, the clothes dry and dryer, the heat that's needed to get the clothes dry eventually ceded to the environment of the space that contains it. This also applies to the motor and the fan. This also use electricity and ultimately childrens storage contribute to the warmth of the environment.
The drying rack Here is the principle easier. It should air around the wax that contains less moisture than the wax itself, and then the water in the clothes will slowly evaporate and come around as water vapor in the air. The evaporation of water just takes energy, which obscured. Ambient air The result is that the surrounding air cooler.
A comparison of the summer both in the summer is as follows: the drying rack is probably outside, if not in a covered childrens storage area. The heat that it withdraws from the ambient air during the amen get the water out of the clothes is not a problem, it's childrens storage been warm enough. The dryer the other hand will still have power to keep the internal air cycle in motion and will therefore give off heat to the surroundings. In the summer unnecessary and even undesirable, perhaps there should be some extra cooling! Furthermore, it is so that the dryer will work less efficiently with heated ambient air, the ambient air is in fact used in the heat exchanger to cool the internal humid air in the dryer. And cooling does not work so well with warm air. This would be a long dry cycle time as a result.
Winter The principle is as follows. With the drying rack evaporation to take place in the surrounding air. This cools the air and must be heated with central heating (most commonly used in the Netherlands). The condensation dryer uses electricity to the internal childrens storage air (used to cycle) to heat to run. The motor and fan Eventually, all electricity is turned into heat to the air in the area, and the water contained in the receptacle, which is probably still warm before it is discarded. We will have to rely a bit to find out what the most efficient is out.
Analysis Here is an example of a condensdroogjob that Vincent has done for me and measured. childrens storage There is 2.2 liters of water collected, childrens storage which was lukewarm before it was thrown away (about 35 degrees). Meanwhile, the dryer consumes 2.87 kWh. He still has a plate made of consumption. Figure 2: The consumption measured during a condensation drying job
The drying rack drying rack usage will have to evaporate. 2.2 liters of ambient air With a heat of vaporization of water of 2258 kJ / kg, we have to count. I have 2.2 liters of water to be evaporated, and that costs more than 2.2 x 2258 kJ = 5.0 MJ of energy. The 5.0 MJ must be heated by a large number
