Air conditioning

Air conditioning equipment has been widely purchased in recent years, with cooling needs representing up to 2% of household electrical consumption.

HOW TO REDUCE YOUR CONSUMPTION ASSOCIATED WITH THE USE OF AIR CONDITIONING?

Contrary to what happens in the case of heating, it is not usual in our country to build houses with centralized air conditioning installations. This situation means that most installations are made up of independent elements. For this reason, centralized or collective installations are rare, despite being much more efficient and avoiding the need to install appliances on the facades of buildings / houses.

Before purchasing AC equipment, you should seek advice from a qualified HVAC professional (heating, ventilation and air conditioning), so that you are provided with information about the type of equipment and which power is best suited to your needs. In addition, the construction materials used, the orientation of the house and its design also have a great influence on the home’s air conditioning needs.

AC em funcionamento

Um equipamento de ar condicionado em funcionamento representa um custo elevado. Esse custo está diretamente relacionado com o setpoint definido para a operação do equipamento.

Ajuste da temperatura

Ajuste a temperatura de funcionamento para uma mais adequada (18ºC Inverno e 25ªC Verão) esta é uma medida sem custos e que permite poupanças significativas.

Poupança

A alteração de 1ºC na temperatura de funcionamento corresponde a uma poupança de 7% no consumo de energia deste equipamento.

Other tips
  1. When you turn on the air conditioner, do not set the temperature lower than normal: it will not cool the house more quickly, and the cooling may be excessive and therefore result in unnecessary expense;
  2. Installing awnings, closing blinds and sliding curtains are effective measures to maintain the temperature at home and reduce the need for air conditioning;
  3. It is important to place air conditioning units in places that are not affected by the sun or where there is good air circulation;
  4. In case the condensing units are placed on the roof, it is recommended to create a shading system;
  5. The light colors on ceilings and exterior walls reflect solar radiation, thus preventing the heating of the interior spaces;
  6. In summer, you should ventilate the house when the street air is cooler (early morning or evening).
Energy Label

The energy label for air conditioning equipment applies to electrical equipment with a nominal capacity of 12kW or less, for cooling or heating, in cases where the product does not have a cooling function.

There are different labels according to the type of equipment and associated features: reversible (type A), only heating (type B) or just cooling (type C).

How to read the energy label:

AC

Type A energy label (Reversible equipment label):

  1. Supplier name or trademark
  2. Supplier model
  3. Cooling function
  4. Heating function
  5. Energy efficiency class
  6. Cooling / heating load
  7. Seasonal energy efficiency for cooling
  8. Seasonal energy efficiency for heating
  9. Noise emission inside and outside the dwelling (in dB)
AC1

Energy label (type B) (Heating equipment label):

  1. Supplier name or trademark
  2. Supplier model
  3. Heating function
  4. Energy efficiency class
  5. Heating load
  6. Seasonal energy efficiency for heating
  7. Annual energy consumption in kWh / year for heating
  8. Noise emission inside and outside the dwelling (in dB)
AC2

Energy label (type C) (Cooling equipment label):

  1. Supplier name or trademark
  2. Supplier model
  3. Cooling function
  4. Energy efficiency class
  5. Cooling load
  6. Seasonal energy efficiency for cooling
  7. Noise emission inside and outside the dwelling (in dB)
