My portable air conditioner can also be used as a dehumidifier. I can use it in the summer/spring both as air conditioner as well as dehumidifier, and it works really well as a dehumidifier under hot weather. The brand and model is as follows: De Longhi Pinguino PAC N82. In the summer it works perfectly well as a dehumidifier. However, I don't know whether it can be used in the winter at low temperatures -let's say 0-5 degrees Celsius. Can I use a portable air conditioner/dehumidifier as a dehumidifier in the winter at cold temperatures?
Let me also explain how the air conditioner/dehumidifier works. The humidity of the apartment (that is captured by the dehumidifier) is expelled outside the apartment through a plastic hose. Moreover, and in contrast with most dehumidifiers, my air conditioner/dehumidifier does not store the humidity in a bowl in the form of water; indeed, as explained above, the humidity is not condensed in the form of water and is expelled outside the apartment through a plastic hose.
Moreover, I also would like to ask another question: In the case that the air conditioner/dehumidifier should not be used with cold weather, which is the threshold of the temperature under which I should not use it as a dehumidifier?
