Tips To Buy & Used Refrigerator To Save Electricity

In our journey in search of energy savings on electrical appliances, today we talk about the refrigerator. They do not consume a very high power, which is approximately 200W versus a hairdryer (2000w). But, being continually plugged in, it can be responsible for at least 19% of the electricity in our houses.

Our efficiency plan begins with a wise purchase decision, based on responsible use and supplemented with proper maintenance.

Purchase Decision

The choice of the apparatus that we need will be based on three fundamental points:

Our needs and habits:

Number of people in the family, shopping frequency and food habits will serve as a reference. In the market, we will find many models to choose from:

  • Single door with interior freezer. It is best suited for smaller needs.
  • Two doors with top freezer. It offers more versatility but average performance.
  • Two-door bottom-freezer. Characteristics similar to the previous. It gives a better performance. A small fan pulls the cold air from the evaporator and creates homogeneous temperatures in the interior.
  • Combined. These devices have two compartments with independent temperature control. It is the device that has more followers and characterized by a high yield. There are two types of combination: two engines, one for the refrigerator and one for the freezer, or one engine with a three-way valve.
  • No-frost. This type of apparatus has a refrigeration evaporator and it prevents frost. Comfortable to use, but has high consumption.
  • Cooler. This is without a fridge freezer. Can form a cabinet.

Space and aesthetics of the kitchen:

Unlike other appliances, refrigerator electricity consumption will depend not only on the conditions of use but also on the place where is located. It needs to be away from sources of heat or radiation and it should be able to circulate air from the rear. Moreover, if you want to integrate it with the rest of the aesthetics of the kitchen, you should opt for panel (with the door similar to the other furniture in the kitchen but having a panel from which you can easily view and access the buttons) or completely integrated into a furniture.

Energy-Category

We must always choose the most energy-efficient appliance, even though the initial outlay might be greater, it quickly pays for itself with lower consumption. In the case of appliances, cold upper levels are A+ and A++ which may lead to energy savings of 65%.

Responsible Use

We mentioned above that the consumption of our device will depend both on its location and other useful factors that are specifically referenced in the energy label. Please note:

  • Adjust thermostat properly and don’t force it into positions that will make the ice block the evaporator producing continuous motion of the engine and preventing the cold air from being circulated, since the ice is insulating.
  • Arrange the food so that air can circulate freely between them, and do not stick the food to the walls of the apparatus.
  • Do no open doors for long and continuous period of time. For example, do not stop to think about what to cook, with the door open. To keep things into the fridge, place them in an area close to the fridge and then open the door once to put them inside.
  • Do not put hot food yet, wait until it cools off.
  • Thaw food inside the refrigerator. This not only will take the thermal inertia, but will also avoid the consumption of the oven or microwave energy for that work.

Appropriate Maintenance

And do not forget the maintenance:

  • Monitor the rubber door because it decides the degree of isolation of the device and hence the consumption.
  • Check that the bulb goes off when you close the door (just move the weather stripping with the door closed and look).
  • Monitor that frost does not accumulate inside the fridge and defrost the freezer when the ice wall is very thick (8 to 10 mm) following the manufacturer’s instructions.
  • Clean dust from the evaporator (rear coil), regularly.
  • In case you going to be absent from the house for an extended period of time, unplug the appliance and leave its doors open.
