Most asked questions about Mark 2 portable AC exhaust system

How is heat being removed through the Mark 2 AC?

With dual hose venting heat system, the heat is removed from inside to outside through Mark 2 AC. One hose takes in the outside air, then the air flows across the condenser. The heat is transferred to the refrigerant and finally released into the outside air through another hose. The best way to cool down a limited space is to connect the two hoses and separate them slightly outside of the window or outside the door. Both are in the Mark 2 box.

What is the dual hose system?

ZERO BREEZE had integrated a revolutionary dual hose system to draw in fresh outside air and output the hot exhaust air through another hose. Dual Hose allows an intake hose to be used to circulate fresh air inside. No negative pressure in the room. And it provides better performance and maximizes output cooling power.

How to set up the hoses in the window?

The Mark 2 battery package includes two foam adapters. So if you order the battery, you can use the foam adapter to extend the hoses to the outside.

    CAN THE ZBAC BE USED TO HEAT AN INDOOR AREA THROUGH THE HEAT EXAUST HOSE DURING COLD WINTER ?

    Hi @Manneesh, Unfortunately, Mark 2 is an air conditioner without a thermostat.

    Considering that the cooling capacity of Mark 2 is 2300BTU/h , which is quite different from traditional home or car air conditioners. It is not yet possible to achieve constant temperature control in a designated size space.

    *When we are going to cool down a given size space, the cooling effect is closely related to the number of people inside, the insulation condition, the sun exposure, and so on. :)

    Would it be more efficient to only run the exhaust air and have the intake unconnected and have a separate vented fan open on the roof to remove the rooms hottest air? Thinking in terms of a sprinter van with a maxxair fan. Thanks

    Is there any way to setup desired temperature in zero breeze?
