Reducing the load on your air conditioner

The key to reducing the load on an A/C lies in internally generated loads.  Reducing internally generated loads is the simplest step to take towards reducing the overall load on your A/C. This can be done by

  • Shutting off unneeded electrical appliances, lights and equipment.
  • Shifting appliance use to cooler times of the day.
  •  Using local exhaust fans to remove heat and humidity from kitchens and baths.
  • Buying energy efficient appliances

The load on your A/C can also be reduced by improving the building of internal loads. This includes:

  • Increasing insulation levels
  • Shading windows
  •  Reducing air leakage

How can my A/C be more energy efficient?

air conditioner energy efficiency

To improve energy efficiency of your system, it is highly recommended that any leaking ducts become sealed immediately. In addition, you should replace dirty filters, clean the coils, and ensure that your outdoor condenser is not blocked. If buying a new A/C look for one with a high Seasonal Energy Efficiency Rating (SEER). A SEER rating higher than 13 is recommended when considering a new unit.

How do I maintain my system?

It is recommended that the coils be cleaned of any dirt or obstructions at the start of each season. Depending on the system and the consumer, this may require professional to be done.

What exactly is a ‘Ton’ of cooling?

A system which delivers a ton of cooling is one that 12,000 BTU/hour, where BTU is a unit of cooling/heating energy. The appropriate number of tons for a desired space depends on the size of that space. The cooling capacity required is also dependent on the following:

· the number and size of the windows
· the direction the room faces
· the available shade
· how well the room is insulated
· how many people use the room
· what appliances (computers etc.) are in the room

How do filters help filter the air?

air conditioner filter

Filters are located just above the evaporator coils, where they help to remove particles from the air stream in order to keep the air and the air conditioning system clean. Because filters absorb particles from the air, eventually they will get saturated with particle, leading to a reduced air flow through the system. When this happens, the performance of the system declines and can even become a source of air pollution. As a result, it is recommended that a new filter is put in periodically in order to upkeep the efficiency of the system.

How does an air conditioner work?

air conditioner work
Using a set of cold pipes, known as evaporator coils, an air conditioner strips the incoming air of its heat, allowing for the air to be cooled. The evaporator coils contain a liquid, known as refrigerant, which changes into gas form once it has pulled the heat out of the air. The gas then moves to a condenser, which is another coil located on the outside, where it then exchanges its heat and becomes converted back into a liquid. A compressor aids in moving the gas between the two coils, as well as monitoring the pressures in each coil. A motor provides the energy required to allow for this system to propel.

What is an air conditioner?

An air conditioner is a system which delegates the air, temperature and humidity within a given area. It is often used to create a comfortable and cool atmosphere for buildings and motor vehicles, especially during hot summer days. However, it can also be used for heating during the winter season. In addition, air conditioners work to supply a constant and adequate supply of ventilation. A system which is complete with ventilation, heating and air conditioning is referred to as “HVAC”.
