Every time you open your fridge door - or indeed your freezer's door - it allows cold air to fall out onto the floor of the room. If this is allowed to happen for more than a few moments the thermostat inside the fridge or freezer, sensing that too much cold air has gone, will turn on the fridge's motor and compressor pump to cool down the new air. The more the compressor pump and its motor are forced to run unnecessarily, the more electricity would be used, with the consequence that the money to pay for that electricity would simply be wasted.

Knowing those "facts of life" it should be easy to understand why it is better to keep the door closed as much as possible instead of leaving it to hang open for more than the short time it takes to load or unload food from the fridge.

How do you close a car door that is jammed open.?

This happened to my Ion as well about 10 minutes after performing an emergency braking test for my kids. I turn off the child safety locks. I think I also had to hold the door latch in the up position as I closed the door. ( I cant remember if I had to be inside the car or outside of the car). I know I also fiddled with the door locks to make sure I had manually had them unlocked (versus with the remote).

How much energy is wasted by keeping the refrigerator door open while placing food on counter and then returning to the fridge for more ingredients?

Well if you divide the number of items by the distance traveled you will get x. Now x is equivelant to the distance of y which is found through the speed of the door opening and closing due to the turbulence. Now the tricky part. This is where pithagerus' theorem comes into play. If x is equal to y then the number of steps taken will be z. z and x are totally different numbers but as I said before x is equal to y. y is also equal to z. but remember z is not equal to x. So if you take fifteen steps and the distance is 7 meters, you will have the amount of f*cks given by anyone on this entire website. Hope that helped

Why Garage door opener not closing?

If you have a garage door that opens and closes electronically, then check the side of your garage closest to the door for sensors that would be on both sides of the door. If the sun is still out, and shining into the sensors, that may be why. To fix this, stand outside your garage, and arrange your shadow over the sensor, then press the button. Your shadow must be over the sensor until it is finished closing, otherwise it will not work. If this doesn't work, it probably needs to be repaired.

How much does it cost in electricity to open a fridge?

A fridge runs about half the time with out opening the door. Opening the door many times a month might add about 30 hours to the regular run time of the fridge. 30 hours of running a fridge costs about .90 dollar. If you open the fridge about 10 times a day for a month that would mean you open the fridge 90 times. so each opening of the fridge probably costs about .001 dollars. or 1/10 of a penny. Its inserting very hot items or leaving the door open for a long time while deciding what to eat that will cost more. obviously refrigerators run less in the winter unless you heat your house irregularly high and they run more in the summer. And again the price will be a bit more for each door use in the summer as the temp escaping in to the fridge when you open it is hotter.

Goes all the way down and then reverses, the down limit is set too far and it is trying to travel farther than is possible. The sensitivity may be set too light also. On the opener there are adjustment screws for both the travel up and down and the amount of force that is used before it reverses. Sometimes the sensors can get bumped and knocked out of line. The have a little light on them that will light when they sense each other.

Do you close or keep open the ceiling registers of central AC system during the winter?

I close mine. Early in the season, like now, put your hand up near the register and you will feel the warm air from your rooms convecting into the attic. Or you may feel a cold draft from some of them. What is happening is that the ductwork in the attic is becoming cooled; then the warm air from the house is rising into the cool area, setting up a loop in which there is a constant loss of your heated air. It may seem minimal, but over the course of an entire season it adds up. Don't forget the return vent. I replace the filter with a piece of cardboard (try a panel from the box the filters came in).

What is the energy change when a fridge door is left open?

In my particular case, the kinetic energy of my father's hand would be converted into heat energy in that event, resulting in an increase in the temperature of the seat of my pants. Speaking thermodynamically . . . when the fridge door remains open in a sealed room, the fridge keeps removing heat from the room-air that enters it, and expelling that heat into the room, along with the heat of the compressor and circulation fan, causing a continuous rise in the temperature of the room as long as the door stays open. The bottom-line energy conversion is from utility power at the wall-outlet into heat in the room, by way of the motors in the fridge's heat-transfer system.

What friction is used while opening a door?

While opening the door you do work to generate a moment of inertia that opens the door. The moment of inertia= force applied x perpendicular distance between the point of application of force and the axis of rotation. The greater the perpendicular distance the easier it is for you to open the door, i.e. a less amount of force can be applied to open the door. I hope this was useful.
