Efficiency Difference and Reasons
3.1
Efficiency Difference and Reasons
One of the key differences between portable air conditioners and window air conditioners lies in their energy efficiency. Portable air conditioners tend to have lower Energy Efficiency Ratio (EER) ratings compared to window air conditioners.
EER ratings measure the cooling capacity of an air conditioner relative to the electrical power it consumes. Higher EER ratings indicate a more energy-efficient unit.
Portable air conditioners often have EER ratings ranging from 8.0 to 12.0, while window air conditioners can achieve EER ratings of 12.0 or higher. This difference can be attributed to various factors.
Firstly, portable air conditioners typically have dual hose systems, which can increase their energy consumption. The intake hose draws in warm air from the room, while the exhaust hose expels hot air to the outside.
The energy needed to continuously draw in and expel air can reduce overall efficiency compared to window air conditioners that have a single hose system. Additionally, portable air conditioners require flexible ducts for air circulation between the unit and the window.
These ducts are not as efficient as the sealed installation of window air conditioners. The ducts can cause air leakage and temperature fluctuations, reducing the overall cooling effectiveness.
The single hose design of window air conditioners allows for a more direct and efficient exchange of air.

Issues with Portable ACs (Ducts and Air Infiltration)
While portable air conditioners offer convenience and adaptability, they come with some potential drawbacks. Two common issues associated with portable air conditioners are the presence of ducts and air infiltration.
Ducts are necessary for portable air conditioners to circulate air to and from the unit. However, these ducts can introduce inefficiencies and drawbacks to the overall cooling process.
The flexible nature of the ducts can lead to air leakage, resulting in wasted cool air escaping and warm air infiltrating the room. This air infiltration increases the workload for the air conditioner and reduces its overall efficiency.
Furthermore, the heat transfer process in portable air conditioners can be compromised due to the ducts. As the air passes through the ducts, it can pick up heat from the surrounding environment, leading to an increase in the temperature of the cooled air before it reaches the room.
This reduction in cooling effectiveness can result in longer cooling cycles and higher energy consumption.
Rating Systems for Portable ACs (ASHRAE vs DOE SACC)
4.1 ASHRAE and DOE SACC Ratings
To help consumers make informed choices, there are two rating systems for portable air conditioners: the ASHRAE rating and the DOE SACC rating. The ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) rating measures the cooling capacity and efficiency of the air conditioner in a controlled environment.
On the other hand, the DOE (Department of Energy) SACC (Seasonally Adjusted Cooling Capacity) rating measures the performance of the air conditioner in real-world conditions. The ASHRAE rating provides a standardized measure of cooling capacity, expressed in BTUs, along with the EER rating.
This rating allows for comparison between different models and brands of air conditioners. Higher BTU ratings indicate a larger cooling capacity, while higher EER ratings indicate greater energy efficiency.
In contrast, the DOE SACC rating takes into account factors such as climate, temperature, and humidity. This rating provides users with a realistic estimate of how well the air conditioner will perform in their specific geographical region.
It considers factors that can affect the air conditioner’s efficiency, including variations in air temperature and humidity levels, to provide a more accurate representation of its performance.
EER vs CEER Ratings

EER vs CEER Ratings
In addition to the ASHRAE and DOE SACC ratings, it is important to understand the difference between the EER and CEER ratings. The EER rating measures the energy efficiency of an air conditioner when it is running at full capacity.
On the other hand, the CEER (Combined Energy Efficiency Ratio) rating considers the energy efficiency of the air conditioner at various cooling capacities. The CEER rating takes into account the air conditioner’s performance at different cooling loads, which is more representative of real-world usage.
This helps consumers make a more informed decision considering that air conditioners rarely run at full capacity for extended periods. Therefore, the CEER rating provides a more accurate depiction of the air conditioner’s energy efficiency in typical usage scenarios.
Conclusion
In the battle of portable air conditioners versus window air conditioners, there are advantages and disadvantages to consider. While portable air conditioners offer flexibility and convenience, their energy efficiency may be lower compared to window air conditioners.
