3 Key Features to Look for in an Energy Efficient Air Conditioner

there is a energy efficient window air conditioner in the living room

Cooling Power

The first thing that you want to look at is the capacity that the window AC unit has to cool things down. This parameter is provided using British Thermal Units (BTU) which represents the amount of heat that an air conditioner can remove from any room within an hour. The values for a BTU number vary typically between 5000 BTU and 15000 BTU for residential applications.

Finding the right BTU number for your situation is extremely important. Under-sizing can lead to the AC unit running continuously to try to cool down a large area, meaning a higher energy bill. However, installing unit that has BTU capacity too large for its area will mean that the air conditioner will means you will be paying more for something that a smaller unit could have done. In addition, oversizing can also lead to other problems such as moisture, low air quality, noise, and a higher wear and tear rate.

Therefore, it is extremely important to properly and accurately size your AC unit as we will explain in this buying guide.

Dimensions – Installation

Usually, window air conditioners are designed to be installed in standard double-hung windows or a sliding window. If you are thinking of installing it in a larger window, most air conditioners include side curtains to seal off the extra area on each side of any window. If you are looking to install it in the smallest window that you have at home, getting the correct dimensions is highly important The best approach is to carefully measure the window dimensions where the AC unit is to be installed.

Features and Operation Modes

Features and operation modes of the AC unit can tilt the balance in favor of or against the model. This refers to:

  • Fan speed adjustment
  • A remote control temperature sensor
  • An automatic timer
  • Sleep mode function
  • An energy-saving mode
  • Air direction control
  • A washable filter
  • Dehumidification and heating functions
  • Energy efficiency rating or combined energy efficiency ratin

What Makes These Air Conditioners Energy Efficient?

For an air conditioner to be considered an energy efficient unit, it must have the Energy Star label and it must have a specified energy efficiency rating (EER).

The EER represents the ratio of the cooling power (in BTU/hr) to the electrical power input (in watts) at 95°F/35°C. Basically, it provides a reference for how much cooling energy can be obtained from the unit based on a specific electrical power consumption. The higher it is, the more energy efficient it is.

Another parameter commonly used in this matter is the combined energy efficiency ratio (CEER) which is the new adoption (as of June 20140 made by the Department of Energy to categorize the efficiency of AC units. This considers both the energy used while the air conditioner is running, and the standby power consumed when the unit is not cooling but is still powered. Efficient window AC units should have at least an EER or CEER of 11.

Although SEER (Seasonal Energy Efficiency Rating) may be another parameter that you hear about, this is not applied to window AC units, but is used for central air conditioning measurements. The best energy efficient central air conditioner should have a SEER of 14 or higher.

What are the Most Efficient Air Conditioners?

If you are looking for the best energy efficient window air conditioners on this list, then look for one of the models from our top 5. These rankings consider the cooling capacity, the EER, and the room size as well.

How to Calculate What Size Air Conditioner You Need?

According to the U.S. Department of Energy, it is recommended to size the A/C unit by assuming 20 BTUs per square foot of living space. However, other factors also influence the thermal capacity of the air conditioner. For instance, the height of the ceiling is a reference for the volume of air that needs to be cooled. Also, sun exposure and the external ambient temperature of the location play an important role because these can increase or reduce the capacity needed by 10%.

As the thermal load increases inside a room based on the number of people that generally inhabit the area, it is also necessary to increase the BTU capacity (generally by 600BTU) starting with the third person inside the room.

Since these are all different variables, the most accurate way to find out your BTU requirements according to Energy Star standards is to use this BTU calculator. These sizing parameters can also apply to an energy efficient portable air conditioner, although they are less reliable due to high variations in the coverage area. Moreover, if you are thinking of installing a central air conditioning system, you must also adjust for air leaks and perform a periodic air quality test.

All of these considerations can be summarized according to Energy Star rating requirements by using the following table. It is important to know that despite the value shown on the calculator, you will need to adjust according to the available BTU standard values available in the market. Table 2 will give you a reference for these values along with the recommended cooling power according to the square footage.

Where Can You Install an Electric Vehicle Charging Station?

Where Can You Install an Electric Vehicle Charging Station?

Carlos

Written by qualified solar engineer Carlos. Last updated:

Electric vehicle charging stations are flexible devices that can be installed outdoors (on an exterior wall) or indoors (in your garage), inside your property. More and more people are learning how to charge their electric vehicles at home. It is needed in order to switch to a more sustainable, eco-friendly lifestyle.

If you’re looking to install an electric vehicle charging station in your home, it’s probably time to take a look at the best EV chargers for your needs. When picking one, there are several factors that should be taken into consideration. In this article, we’re going to discuss those factors. We’re also going to talk about how to understand charging levels and how to apply them to your needs. This will allow you to make a well-informed decision.

Know your EV

The first thing that you must know is the energy demand of your EV. This is a parameter that can be easily found in the datasheet or the specs of your electric car. Electric cars use DC batteries that can hold a maximum energy capacity once they are fully charged, this parameter is expressed in kWh. For instance, for the 2019 Kia Soul EV model, the battery capacity is 31.8kWh.

Understand the different EV charging station levels

The charging station acts simply as the point of transfer from the grid to your vehicle, however, almost all the charging process is actually performed inside the vehicle’s onboard charger. Inside this device, there is a conversion from alternating current (AC) to direct current (DC) through an electronic rectifier that allows charging the battery in DC.

Now, there are three categories of charging stations that are linked to the three levels of charge.

The first level of charge (level 1) is included with any electric car at the time of purchase. Under this level, the electric vehicle can be connected to any standard 120V AC wall outlet such as the NEMA 5-15 and can provide up to 3kW of power with an average charging speed of 8-16 hours. This charger uses a standard connector known as the J1772, which allows charging any electric vehicle.

The second level (level 2) needs to be installed with a charging station and connected to a 240V supply. This type of charger can provide from 3kW to 22kW of power (depending on the brand) with ampere ranges between 15A and 50A. Unlike the previous models, level 2 chargers can reduce charging times to 3-8 hours. This type of charging station will be the one that is most likely to be installed at your home since it allows you to increase the charging rate and can be installed at your home with small modifications. This charger type also uses the J1772 connector and can be installed either outside or inside the house (depending on the enclosure type of the charging station).

Finally, the third level is known as the DC Fast Charge (DCFC). This is the fastest charging station (as fast as 30 minutes) but is also the one with the highest costs. It also needs a 480V DC supply which is not available in most households, therefore, it is more suited for companies and commercial applications.

Choose the Corresponding Charging Station Level

Based on the two previous sections, you will be able to find out what is the minimum amount of hours that you need to charge your EV daily.

This can be done by using the kWh capacity of the battery and dividing it by the power output of the charger. For instance, the Siemens US2 level 2 charger has a 7.2kW power output. If we were to use this model to charge 2019 Kia Soul EV car, then we would need 31.8kWh/7.2kW=4.41 hours.

Charging time formula

Based on this charging time and on your driving daily patterns, you will be able to know the type of charger that you will need. If by using a level 1 charger, you are missing time to fully charge it or to reach the required miles per day, then you will need to do an upgrade and install a level 2 model.

Adapting your site

Once you have decided on the type of charging level that you want to install at home (level 1 or 2), the next step is adapting your site. Depending on the EV charging station, you will be able to install it both indoor or outdoor, or only indoor. This is directly related to the enclosure type of the charger and cable. If it’s suited for outdoors, then it probably has a NEMA 4 type enclosure or higher as it prevents water from entering the charging station. If you are not familiar with the enclosure types, you must not worry as the manufacturer will always tell you if the charger is suitable for outdoor conditions (including rain and snow).

If it is intended only for indoor use, then there is no other alternative than to install it inside the garage. Keep in mind that even if the charger needs to be installed indoors, you can still charge the car from the outside by running the 25-foot charging cable that the device is likely to have, it does not matter if it’s raining or not. This is useful to know for those who have enough room to install the indoor level 2 charger inside the garage, but not enough room to park the car inside. If you intend to do this, remember not to entirely close your garage; leave a small gap so the cable does not to suffer underneath the weight of the garage door.

Meanwhile, for those cases in which both outdoor and indoor charging are possible and you choose to install outdoors, you should do a hardwire 240V installation because it provides the best weather protection for electrical power connections. A plug-in unit installed outdoor is also an option, but you must have a watertight cover for the plug and the outlet combination. The plug-in will have to be attached to a freestanding pole or an external wall as can be seen in figure 3.

external plug-in for ev charger

No matter where you choose to install the EV charging station, inside or outside the garage, you will need a 240V outlet for level 2 chargers. For this purpose, it is recommended to adopt a dedicated circuit in the main electrical panel of the household. Keep in mind that in some cases, your main electrical panel may not have enough room to install the corresponding 2-pole breaker for the charger, therefore, you will need to install a separate panelboard. This also involves a dedicated conduit that runs from this panelboard to the EV supply equipment location. Additionally, you will need to add four new wires through the new conduit: a ground wire, common wire, and two phases which will be attached to the double-pole breaker. As you can see, it may become a demanding task. It would be best to hire a professional electrician who verifies that the building codes are met. Keep in mind that the EV charging station should always be mounted on concrete.

Finally, some charging stations will be able to communicate with local Wi-Fi networks or through ethernet cables. This communication is very important to manage the user interface and messaging for charging schedules. Therefore, when assessing the sites for the installation of the charging station, the availability of a good Wi-Fi signal should be considered in the scenario. If not available, especially in the garage, then considering signal repeaters would be wise.

5 Key Features to Look for in an EV Charger

a car connected to an ev charger

Electrical Specs

The electrical specs are the first and most important factor that you must look for when selecting electric car battery chargers.

These specs are related to electrical current, power, and voltage. The power is the best indicator of the charging speed that you can expect. The higher the output power, the faster the charging process will be.

The charge time can be determined by checking the amount of energy that your car’s battery needs. This will be expressed in kWh. Simply divide the kWh (energy) by the kW (power) and you will find out the number of hours that will be required to charge your vehicle.

NEMA Outlet Connection – Adapters

Another fact is to verify the NEMA outlet connection that you can couple the charger too. Even among level 2 chargers, there can be different 240V or 220V outlet types, therefore, you must verify that the one available in your garage is the one suitable for your car.

There are some cases in which you may not have a 240V outlet in your garage. For those cases, some home EV chargers will integrate an adaptor to couple the cable with a 110V outlet. That way, you would be able to use 120V, 220V, or 240V outlets. This is a simple solution. In the long term, you might want to consider making a 240V outlet connection for your garage as the performance and charging speed will reduce drastically.

Enclosure Rating – Indoor or Outdoor

Not every charger is suitable for working in outdoor environments with rain or snow, so you need to learn where to install an ev charging station.

Connectivity and Ease of Use

Some home EV chargers are designed with the possibility to work under a Wi-Fi connection. This allows you to couple the charger with a mobile app that offers flexible control via remote and that can even be controlled by using Alexa.

The ease of use is also related to the cable length of the charger. The longer it is, the easier it will be for you to connect the charger every day without much damage to the cable.

Installation

Finally, the other factor that must be considered is the installation type. You must find out if the charger needs to be hardwired or if it will be plugged in.

Hardwire requires an internal electrical connection of the cables through the walls or underground. This is harder to install, but it is also harder to steal and more secure from a technical perspective — especially if it will be mounted outdoors. It is also cheaper.

The plug-in is much easier to install, assuming that you already have a suitable outlet for the charger. It is not as secured and is probably more expensive.

What are the Different Types of Electrical Vehicle Chargers?

The electric car chargers can be classified according to their speed of charge according to the following types:

Ultra-Rapid Chargers

These chargers can provide between 50 and 150kW, which drastically reduces the charging times. Some models like the Tesla Supercharger are classified under this regime, but they are not compatible with all EVs. These models are typically level 3 chargers and they can charge an EV in an average time of 30 minutes, but they are very expensive.

Fast Chargers

Meanwhile, fast chargers are those that can power EVs with a rating between 3kW and 20kW. These models are level 2 and they can charge an EV in 3-8 hours. The equivalent ampere output for these chargers will be 30-amp, 40-amp, 50-amp or any in between.

Slow Chargers

Finally, the slow chargers are only suitable to charge the EV during the night. These have a capacity up to 3kW and they are level 1 EV chargers generally. These models take between 9-16 hours to charge an EV.

What are the Differences Between the Different Levels of EV Chargers?

There are several differences between EV charger levels.

The first difference lies in the input voltage that they can connect themselves to. While level 1 chargers must be connected to a 110V supply, level 2 models must be connected to a 240V supply. On the other hand, a level 3 EV charger, also known as DC Fast Charging (DCFC), must be connected to a 480V DC supply. As you can see, only the first two are suited to be called home electric car chargers because the level 3 model can only be used for industrial or commercial applications.

The second difference lies in the power that each one can supply as was explained in the section before. This is a direct consequence of the voltage supply, the higher it is, the more power the charger can supply. This also impacts the charging speeds.

Also, the wall outlets to which the charger can be connected to will vary according to the level. Finally, the type of connector of the charger will also change according to the level. While both level 1 and level 2 models will use J1772 connectors, the level 3 charger will use a CHAdeMO or SAE Combo port. Table 1 shows a schematic overview of the differences between levels while figure 1 shows the outlet types, check which one is the one available in your garage.
