portable air conditioner
What is a real portable air conditioner?
There are a large number of air conditioners, and there are also a variety of different kinds of portable air conditioners in the market, why do we need another so-called portable air conditioner?
Traditional air conditioners are designed for fixed spaces and need to be installed in fixed locations. Even for those home mobile portable air conditioners are restricted to be moved indoors by wheels and cannot carry outdoors.
Most essentially, they will need a household AC 110-240V, which is beyond practical outdoors. So that’s why Zero Breeze address these issues to make an air conditioner truly PORTABLE
ZERO BREEZE MARK 2, from the very beginning, has been designed for optimal portability from all aspects.
In order to create a highly flexible, high-performance system that is not restricted to a home power supply, the MARK 2 was designed from the inside out. This is a truly portable air conditioner that allows you to enjoy cold air anywhere.
From the iconic handles to mobile-friendly designs
From suitable weight to compact size
From small but strong compressors to delicate air duct systems
From 24V operating voltage to high-performance batteries
Mark 2 keeps breakthrough innovation for portability
As the core of the air conditioner, Zero Breeze clearly defined that the small size, lightweight, low power consumption, and DC compressor are the preferred goals of Mark 2. To achieve this goal, we worked hard with professional refrigeration engineers, compressor R&D experts, top manufacturers. Now you can see, MARK 2’s compressor is about the same size as cola cans, less than a quarter of the size and weight of traditional compressors. It indeed costs 4 times as more than a traditional compressor, but truly worth it. Because, this, is what rocks the portable air conditioner market.

24V DC voltage is much safer than household AC power. At the same time, because it does not need to go through the inverter, direct battery power is more energy efficient.
Traditional portable air conditioners are more than 800w, which requires too much electricity. MARK2 is only 240w, it is easier to be powered by other power sources, and it can get longer cooling time outdoors.
When we first started creating outdoor cooling equipment, the use of micro compressors would be the best solution.
Although the traditional air-conditioning compressor is cost-effective, it is designed for large space and large equipment, without considering weight, size, too bulky when moving, and cannot be powered by batteries.
THERMOELECTRIC COOLING has the advantages of simple structure, simple installation, and most of the equipment is used for heat dissipation, but the energy efficiency ratio is too low and the energy consumption is too high. For a 2300BTU cooling capacity, it requires power consumption of up to 1300W, while the Mark 2 consumes less than a quarter of it.
THE BLOCK HEADING, the least technology-dependent solution, relies on ice to cool down. Its cooling effect is very limited, and it is very bulky, and the melted water will cause a lot of troubles.
EVAPORATIVE COOLING, the solution with the worst effect by cooling water by evaporation. It can also make you feel worse when you are in a humid environment.

First of all, the cost of conventional compressor refrigeration equipment is not low, and the cost of micro compressors is even higher.
The experiences of the outdoor portable compressors are almost blank. There are some compressors for communication equipment, but those are not very environmentally friendly, and the noise is very loud. There are also some compressors for small refrigerators, but due to different uses, energy and working conditions, they also can not meet the needs of outdoor air conditioning refrigeration.
We need to develop a dedicated compressor. We were constantly optimizing for many relative contradictions such as volume, speed, displacement, power consumption, compression ratio, and strive for more effective performance. The compressor is very sophisticated equipment. The production of compressors requires specialized manufacturing equipment and specialized laboratories. We hired senior doctors of compressors to join us and invest a lot of human resources and funds.
We continuously combined the scene experiment test on the compressor. Finally, the 2300 BTU 24 inverter compressor came to the world.
From the principle of energy conservation, high power requires more power consumption. the energy consumption of small air conditioners is 3-4 EER and 450W for 5000BTU. If we use our current 840Wh battery, it can only work for more than 1 hour. Besides, the 5000BTU cooling capacity will make it bulky and cumbersome, and it will require a larger capacity battery. The battery will be bulky and lose the essence of portability.
Also, we don't want to use a high voltage for safety concerns. 24v will be safer. If the power consumption is 450w, the current will be close to 20A at 24v, which will bring hidden dangers to the users.
The space that needs to be cooled in outdoors is not too big. The 2300 BTU is enough for individuals, families of three, and small trailers, and the battery weight and input are suitable and safe.
The outstanding performance of the Mark 2 requires a powerful air duct system.
Small size, large air volume, and high wind pressure are the three mutual constraints in air duct design, it is difficult to take all of them into account. To achieve this, Zero Breeze developed a unique air duct system which allows reducing the size to a very small size while satisfying large air volumes.
Mark 2's innovatively designed dual-pipe cooling system, built-in powerful 24v variable frequency centrifugal fan, can drive 120CFM (200 cubic meters/hour) air heat exchange in such a small space, even under the load of 2 meters long extension pipe. On the other side, the innovative compact forward centrifugal fan draws air through the evaporator, blowing the cooled air directly in front of you.
