How does ventless air conditioner work

When we talk about air conditioners, we typically mean machines that soak up heat and humidity from your room air and move it outside.

Evaporating water cools air the same way melting ice cools your food in a cooler : By absorbing extra energy as it changes between phases. Think of cooling with evaporation like starting a party: Liquid water is a bunch of low-energy molecules just relaxing together in a corner, and evaporated water is like hyperactive high-energy molecules dancing all over the room.

To change from relaxed to hyperactive, water needs to soak up a lot of heat energy. Evaporative coolers will continue working until the air starts to become too humid to soak up more vapor. The drier your air, the better evaporative cooling works. On the map above, we used data from the National Atmospheric and Oceanic Administration to map out summertime temperatures and humidity in three conditions where evaporative cooling can work:. The difference between cooling in the ideal zone and in areas with higher humidity is extreme.

Choosing between these two types of systems comes down to climate. With ductless AC, only small incisions need to be created to mount the indoor unit and connect it to the outside condenser. This means more cool air stays in each room. The indoor unit for ductless air conditioning systems is wall mounted. For some homeowners, this aesthetic is undesirable. A ducted HVAC system has air intake registers at various places within the house.

However, if you can get past the appearance of a wall mounted unit, ductless AC is just as effective as a ducted central air conditioning unit. Depending on how your home is built, ductless can be the ideal solution. Mini-splits can provide heating and cooling for the entire house in many cases.

In certain scenarios, ductless has a clear advantage over central air. If you want to know more about whether a ductless heating and cooling system is the right fit for your home, fill out our free estimate form or call Ventwerx at in San Jose, or in Morgan Hill.

How do Ductless Air Conditioners Work? Components of the Ductless System and Basic Operation Like a central air conditioning system , the ductless AC system extracts heat from the air inside the house, moves it though a conduit, and expels the heat into the outside environment.

Indoor Ductless Unit The indoor unit consists of the evaporator unit. Cold air is blown back into the inside room. Condensing Coil The condenser coil turns the hot refrigerant from a high-pressure gas into a high-pressure liquid. Mini-Split Air Conditioning Systems A mini split has a single indoor fan coil and single outdoor condenser. Multi-Split Air Conditioning Systems A multi-split system has one condenser unit that is connected to more than one indoor air handler.

Outside of mild climates, an electric heat strip can provide supplemental heat. Pros and Cons of a Ductless Air Conditioning System As with a central air conditioning system, there are upsides and downsides to a ductless AC system.

Pros of Mini-Split Systems Three big pros to ductless AC are energy efficiency, less air leakage, and less noise during operation.

Lastly, ductless cooling units create less noise than central air conditioning. Cons of Ductless Air Conditioning The indoor unit for ductless air conditioning systems is wall mounted. That means they can both heat and cool your home, eliminating the need for a separate heater. Related: What is a Heat Pump? Since each area of your home has a separate indoor unit, you can individually control the temperature of each part of your home.

And duct leakage is a real problem with central air conditioners. For an exact price for your home contact us online or call us at to set up a free, in-home estimate for a mini-split system. April 22,
