Another thing to remember is the humidity levels. During this period, dendrobiums do not need a lot of moisture. Very little water will be enough to keep their roots alive. Also keep in mind that their roots constantly need plenty of air circulation so you should place them where there is a lot of fresh air.
Remember, that is based on energy usage, not comfort-levels, which are the purpose of having an air conditioner, in my not-so-humble opinion. Fact: At night, the ideal temperature comfort range for Americans drops to 65 to 72 degrees Fahrenheit (or about 87 degrees if you are my wife).
To understand how cold an air conditioner's output should be, it's important to understand the difference between supply air and return air. In HVAC terms, supply air is the hot air outside your home.easuring Air Temperature from Your Air Conditioner. Your air conditioner can provide about 20 degrees of cooling from the supply air and return air that passes over the evaporator coils. In other words, on a 100-degree day, even the most efficient air conditioner could only achieve an 80-degree inside temperature.
