Controlling indoor humidity is even more critical than ever because of COVID-19. The virus thrives under both extremely high and very low humidity environments. It’s only one more justification (beyond comfort) to maintain the humidity between 40 and 60 percent for most rooms if you’re working your way through another muggy August (and you’re worried about health conditions), read on to know more about AC humidity control problem and why your air conditioner may not be up to the challenge.
- Large AC System for space volume.
When we think about the size of an air conditioning system, the first thing is its cooling power, not the actual size of the device. It isn’t the only thing that people forget about the air conditioning scale. When you’re not an air conditioning specialist, it may sound counter-intuitive to suggest that your air conditioner is too large to effectively do the job.
The truth is that the bloated AC machine performs a bad job at regulating both temperature and humidity. The efficient compressor is put on and off constantly, and the machine rarely works long enough to extract moisture from the air. Your AC size must be carefully measured using the load estimation tool. Unless the air conditioning has been purchased and built by a supplier rather than a professional AC service, there is a moderate risk that this has been achieved improperly. That’s how many homes and businesses end up with oversized units that provide poor AC moisture control. You may probably need to add a lower capacity AC device to solve this issue.
- When an AC is restricted to one level of speed.
An air conditioner that can only operate at one speed—on or off—may have the same issues as one that is too large for regulating AC humidity. If the unit can only run at one speed, it will turn on and run full blast until the air reaches the set temperature. So it signs off until the temperature increases slightly above the thermostat level. It also implies that the machine will not work regularly enough to extract moisture. This is particularly valid when the temperature is not too hot, yet the air is very humid.
If it’s time for a new air conditioner device, talk of investing in a modulating AC system such as VRF SYSTEM. A VRF (Variable Refrigerant Flow) system will operate longer at lower power, and it does a lot better job at regulating air conditioner humidity and delivering more stable temperatures.
- Presence of Negative Air Pressure in Room
Negative air pressure is the product of a weak ventilation system. In a nutshell, this implies that you’re venting so much air out of your house. It can happen in a restaurant with a strong kitchen exhaust device.
If you have downward energy, the climate seeks to balance itself by pulling more fresh oxygen in whatever direction. For example, whenever someone opens an outside door, a gust of wind appears to enter the room. External airflow passes through every little opening in the building. So what occurs as the relative humidity outside hits the 70’s, 80’s and above?
You’ve guessed it; all that muggy airflow enters into the building. If the situation is difficult enough, the AC will not be able to keep up, so the regulation of air conditioner humidity could be affected. Changes in the configuration of the ventilation system may be required to fix this problem.
- When using the incorrect thermostat settings
You may assume you ‘re getting rid of more humidity by using your FAN ON thermostat settings. When you use this configuration, the fan should work continuously even though the AC is not working.
The fan pushes the air sometimes without the AC going, and you may feel like you have some cooling gain. Yet you find the levels of humidity worse. You may end up blowing the moisture that your AC eliminated back into space to drain away.
- If the older AC system clearly can not withstand the load.
When the air conditioner ages, components rust, and they can not work as well as they used to. This risk improves because the system has not been managed constantly. In addition to inconsistent temperatures and inadequate cooling, you will begin to notice poor air conditioner humidity control.
