Air Conditioning Your Home
In summer, high relative humidity, elevated air temperatures and bright sunshine can sometimes combine to produce an uncomfortable indoor environment. An air-conditioning system can provide comfort for occupants by lowering the air temperature and the humidity level in the home. Options that are open to the consumer include a room air conditioner, a central air conditioner or a heat pump. The best choice of system will depend on your circumstances; therefore, it is worthwhile taking the time to evaluate your needs.
Does the whole house need to be air-conditioned or would cooling in one or two rooms be sufficient? Room air conditioners offer an effective, low-cost approach to providing comfort in a small space, up to three rooms, with minimum installation effort.
Central air conditioners and heat pumps are used to cool the entire space. Central air conditioners are cooling-only products, whereas heat pumps provide winter heating as well. The cost of a heat pump is greater than that of a central air conditioner, which is greater than that of a room air conditioner. If you are currently renting your home or apartment or if you are planning to move in the near future, a significant investment in either a central air-conditioning system or a heat pump probably does not make sense.
However, a room air conditioner can be moved with you and re-installed in another residence. If your home has a central air-duct system and an acceptable place to mount the outdoor unit, installation of a central air conditioner or heat pump should be straightforward. In bungalows with unfinished basements, the addition off a duct system may be relatively simple and inexpensive, but in other cases, this option is usually expensive and frequently impractical.
In these cases, there are two other options for central systems:. There are a number of things that you can do to reduce the need for mechanical cooling in your home, thereby minimizing the capacity and cost of the equipment that you purchase and the amount of electricity that it will consume.
Actions you can take to reduce cooling requirements are as follows:. Becoming informed about all aspects of air conditioning your home is the way to ensure that the correct choices are made for your particular cooling needs. This booklet identifies the commonly available air-conditioning equipment and discusses factors involved in selecting, installing, operating and maintaining an air-conditioning system.
It provides you with a sound basis for making a smart purchasing decision. As mentioned previously, there are two basic types of air conditioners — room air conditioners and central air conditioners.
However, there are several different kinds within each type. Variations of room air conditioners are as follows:. Here are some common terms you will come across when comparing and determining the best choice for air conditioners.
The refrigerant is a substance that circulates through the air conditioner, alternately absorbing, transporting and releasing heat. A coil is a system of tubing loops through which refrigerant flows and where heat transfer takes place. The tubing may have fins to increase the surface area available for heat exchange. The evaporator is a coil that allows the refrigerant to absorb heat from its surroundings, causing the refrigerant to boil and become a low-temperature vapour.
The compressor squeezes the molecules of the refrigerant gas together, increasing the pressure and temperature of the refrigerant. The condenser is a coil that allows the refrigerant gas to give off heat to its surroundings and become a liquid. The expansion device releases the pressure created by the compressor. The plenum is an air compartment that forms part of the system for distributing warmed or cooled air through the house.
It is generally a large compartment immediately above the heat exchanger. One Btu is the amount of heat energy given off by a typical birthday candle. A kW , or kilowatt, is equal to watts. This is the amount of power required by ten watt light bulbs. A ton is a measure of cooling capacity. It is equivalent to 3. The capacity of an air conditioner is a measure of the maximum rate at which it can remove heat from the conditioned space.
Capacity is expressed in British thermal units per hour or tons and is determined under a specific set of test conditions. It is calculated to determine the capacity of air conditioner required. Heat gain is a term applied to various components of the heat load, such as appliance heat gain and solar heat gain. All of the heat gain components are summed to calculate the cooling load. Oversizing is the practice of selecting an air conditioner with a cooling capacity greater than the cooling load.
Undersizing is the practice of selecting an air conditioner with a cooling capacity smaller than the cooling load.
The energy efficiency ratio EER is a measure of how much cooling effect is provided by the air conditioner for each unit of electrical energy that it consumes under steady-state operation.
It is determined by dividing the cooling output of the unit, in British thermal units per hour, by the electrical power input, in watts, at a specific temperature. The higher the EER , the more efficient the unit. The seasonal energy efficiency ratio SEER is a measurement of the cooling efficiency of the air conditioner over the entire cooling season.
The bel B is a unit of sound measurement equivalent to 10 dB decibels. One bel is the threshold of human audibility. The sound level in a busy typing and accounting office would be approximately 6. Both room air conditioners and central air conditioners are covered under Canada's Energy Efficiency Regulations, which came into effect February 3, These regulations, which cover several types of energy-using products, help Canadians save money and protect the environment by reducing electricity demand.
Improving energy efficiency reduces greenhouse gas GHG emissions that contribute to climate change. Under the Regulations, energy-using products, such as room air conditioners and central air conditioners, must meet minimum efficiency standards of performance if they are to be imported into Canada or shipped across provincial and territorial boundaries. The Energy Efficiency Regulations specify that room air conditioners must carry an EnerGuide label, which helps you obtain consistent and reliable information about the relative energy efficiency of room air conditioners on the market.
You may already be familiar with the EnerGuide label found on major electrical household appliances, such as refrigerators, ranges, freezers, dishwashers, clothes washers and clothes dryers.
Although the label for room air conditioners looks similar to the one found on appliances, it is quite different. The large bold number found on the EnerGuide label for room air conditioners is known as the EER of the unit, and the higher the EER , the more efficient the room air conditioner. The inverted triangle and the graduated bar can be used to compare the performance of a particular model with others of the same class.
Class refers to the type louvred or non-louvred and cooling capacity category, which are indicated near the bottom of the label. The further the triangle is to the left of the scale, the less efficient it is. The further the triangle is to the right of the scale, the more efficient it is. It ranks room air conditioners by type and cooling capacity, starting from the highest EER to the lowest.
To earn this status, a room air conditioner must exceed the Government of Canada's minimum standard of energy efficiency by at least 10 percent. Room air conditioners contribute more to the summer peak demand for electricity from the electricity grid than any other household appliance. On hot days, when the demand for electricity for air conditioning increases, the generation of coal-fired electricity can soar, with a corresponding increase in nitrogen oxides NOx , sulphur oxides SOx , carbon dioxide CO2 and other emissions that lead to smog, acid rain and climate change.
Certification organizations accredited by the Standards Council of Canada, such as CSA, operate energy efficiency verification services for manufacturers, distributors and importers of room air conditioners to help them demonstrate compliance with federal and provincial regulations.
These verification services assess the products' performance against mandated requirements and put in place a process to ensure that production units continue to meet these requirements. As mentioned earlier, central air conditioners must meet minimum efficiency standards of performance under Canada's Energy Efficiency Regulations, as well as under similar regulations in many provinces.
These regulations specify the minimum seasonal energy efficiency ratio SEER for central air-conditioning equipment. The energy efficiency rating scale appears under the EnerGuide logo on the back of the manufacturers' brochures.
As with the EnerGuide label for room air conditioners, the inverted triangle and graduated bar can be used to compare a particular model with other model designs and types. The standard specifies the tests and calculation procedures to be used to determine SEER and capacity ratings. The standard also specifies the minimum efficiency requirements. Certification organizations accredited by the Standards Council of Canada, such as CSA, operate energy efficiency verification services for manufacturers, distributors and importers of central air conditioners to help them demonstrate compliance with federal and provincial regulations.
Central air conditioners are major contributors to the summer peak demand for electricity from the electrical grid. On hot days, when the demand for electricity for air conditioning increases, the generation of coal-fired electricity can soar, with a corresponding increase in NOx, SOx, CO2 and other emissions that lead to smog, acid rain and climate change.
A room air conditioner is essentially a smaller version of a central air conditioner and is intended to cool only a small area, usually one room. Powered by electricity, it removes heat from the living space to maintain comfort conditions during hot, humid weather and conveys it to the outdoors.
Unlike a central air conditioner, no ductwork is required, and all components are built into a single package that is mounted in a window opening or through the wall Figure 3. Smaller capacity room air conditioners are portable, as they are easily moved from one room or residence to another. Two major categories of room air conditioners are available: units with louvred sides that are intended for installation in window openings, which are the most common type, and units without louvred sides intended for through-the-wall installation.
A fan circulates room air through the evaporator, which contains low-pressure refrigerant. Evaporation of the refrigerant cools the tubes and fins, extracting heat from the air and causing moisture in the air to condense on the evaporator's outer surface.
The cooler, drier air is returned to the room, and the gaseous refrigerant leaving the evaporator is drawn into the compressor where mechanical compression raises its temperature and pressure. The hot, high-pressure refrigerant passes through the condenser, where it loses heat to outdoor air which is blown over it with a second fan and condenses.
This high-pressure liquid refrigerant passes through a restriction and into the low-pressure side of the circuit, and the entire process is repeated. The efficiency of room air conditioners in converting electricity into cooling effect varies widely, depending on the manufacturer's design choices. Models for window mounting are available with EER ratings between High-efficiency units generally incorporate efficient rotary compressors, large evaporators and condensers with louvred fins and internally rifled tubes, as well as efficient fans and a slinger ring to deposit water collected from the evaporator onto the hot condenser.
Minimum efficiency units tend to use small conventional heat exchangers and standard compressors and fans. While higher efficiency units are more expensive to manufacture, retail prices do not necessarily reflect this premium. Select a unit with as high an EER as is practical, to minimize operating costs. The amount of cooling that the air conditioner must provide to maintain comfort conditions is called the cooling load.
It is affected by the size of the room, the size and orientation of windows, attic and wall insulation levels, and the amount of heat being generated in the room, etc. Ideally, the unit should be sized by a qualified air conditioning contractor, using detailed calculations that take into account the size of rooms, insulation levels, size and orientation of windows and doors, shading, number of occupants, appliances, lighting, climate, etc.
Annex A provides a capacity estimation procedure for room air conditioners. Although this procedure is fairly detailed and complex, it can provide an accurate cooling load for your particular needs.
