Single Vs. Double Exhaust Hose

Single Vs. Double Exhaust Hose

Single Vs. Double Exhaust Hose

Portable AC units that are equipped with a single hose capture the air from the surrounding area, cool it down, and then blow most of it back into the room. The remaining is used to cool the unit, and is then expelled through the exhaust. Because the air from inside the room is used to cool the appliance, the pressure tends to be negative, which results in warm air flowing into the room to restore the equilibrium. For a more in depth article of how portables ac works click the link.

Dual hose portable units capture the air from the surrounding area, cool it and then return it all to the original space. Cooling ambient temperature results in the accumulation of heat in the appliance. The unit draws air from outside through a separate hose, cools the compressor, and then expels it through the exhaust hose, ensuring that the pressure is unaffected.

Check the energy rating of the unit that you purchase as the use of fans and the method used to chill the compressor can influence its energy efficiency.

Unique Features to Consider

  • Programmable Thermostat – allows you to determine the exact temperature that you require in the affected space. Once the ambient temperature reaches the pre- set condition, the AC will turn off. Some of the best portable AC units will even allow you to pre-program the unit to switch on at a specified time.
  • Auto Drain System – changes the water caused by condensation into steam so that it can be vented off. You can also consider a portable air conditioner window vent kit if your unit needs to be vented. (R)
  • Remote Control – allows you to control the appliance without approaching it.
  • Heater and AC combination – offering the option of both heating and cooling the room, so it can be used winter and summer.
  • Dehumidifier - helps to remove moisture from the air. Being able to handle humidity is particularly important in the hot summer months.

It is not necessary to struggle through sweltering temperatures this summer. Whether you’re looking for a portable air conditioner for car use, a portable air conditioner for camping, or a battery powered air conditioner to take with you wherever you go, there are options out there. By considering the ambient requirements, cost, and premium features of the best portable air conditioner, you could chill out in the summer months, no matter your location.
