In the winter, we are always thinking about how to save electricity and save fish. Heating is the largest electrical appliance used in fish tanks. It's normal for you to burn three hundred or four hundred pieces a month.
As for the insulation method, we can refer to the thermos cup.
Heat preservation method: add a lid to prevent water evaporation
In physics, water evaporation can absorb heat and take away the temperature of water body, so as to get the effect of cooling.
Factors affecting water evaporation: surface area, temperature, ventilation, surface pressure.
In the fish tank, the surface area is fixed, and the temperature is set at constant temperature. So the ventilation will affect the most direct reason for the evaporation of fish tank water.
So the method is very simple, that is, stamped. A fish jar, a filter cap, a dry and wet separation cap, and a whole fish tank with a chance to evaporate are covered with a lid, so that ventilation can be reduced and water vapor taken away.
Evaporation in a sealed container of liquid vapor continuously, on the surface is constantly setting, when the two simultaneous process to achieve dynamic balance, the macro evaporation also stopped, and the mixture is called saturated steam steam dynamic balance.
Rogue explanation: as long as the fish tank with a lid, the air space in the fish tank is relatively small, the smaller the space, the faster the saturation speed of water vapor. The faster the saturation, the slower the evaporation of water. The relative temperature loss slows down, so as to achieve heat preservation effect.
Example: the thermos cup with a lid, holding time will be long. Open the lid and the water cools off quickly.
Insulation method two: manufacturing insulation
Physics principle: the phenomenon that heat transfers from the high temperature part of an object to the low temperature part is called heat transfer
In winter, the tank temperature is about 24~30 degrees, belongs to a high temperature object, and the surrounding environment is relatively low temperature. So even if the aquarium is full of lids, it will produce heat transfer from the glass.
Although the efficiency of this heat transfer is not as fast as water evaporates. But it is also one of the reasons for the loss of temperature.
The best way to prevent this heat transfer is to heat insulation, and use the object with poor thermal conductivity to wrap the fish tank. Let the fish tank separate from the indoor air. The relative heat transfer will be less.
Thermal insulation material: foam board, foam cotton, quilt and so on.
This method is a little effective, but don't expect to have much effect, for example, the same fish tank, heat insulation may be an hour down 1 degrees water temperature, without heat insulation, may be an hour down 1.2 degrees water temperature. But it's never done twice as much.
To achieve true thermal insulation, you need to have a thick, insulated foam like a refrigerator. Just like the summer transport car popsicle cabinet, a heat insulation layer is thick enough to get enough to play the insulation effect. But the fish tank couldn't do it, and the fish tank couldn't see the fish. The nature of losing sight.
