With its high efficiency design, Coolzy uses special patented technology to focus a stream of cool air and send it towards you, keeping you comfortable.

Unlike other portable air conditioners, Coolzy focuses on cooling people, not rooms by providing a stream of cool air from the front of the unit. The by-product of this cooling is a small amount of warm air (about the same as 3 old light bulbs) that is expelled from the rear of the unit (similar to a small bar fridge). We recommend that in small spaces, this warm air must be allowed to ventilate and escape the room. This can be done by leaving a window or door open.

Fans, no matter how smart they may be, can still only recirculate the same air that’s already in the room.

Other kinds of portable air conditioners use far more electricity or can cause extra humidity, and some need drain pipes or topping up with water or ice.

Since Coolzy creates a cool micro-climate around you, the windows and doors can remain open allowing fresh air to circulate. With split air conditioners windows and doors have to remain tightly closed so there is no fresh air exchange. CO₂ and harmful volatile organic compounds accumulate. Coolzy is a much healthier option.

Coolzy uses very little electric power, only 340 Watts. The heat extracted from the cool air can simply be directed to the ceiling where it is absorbed. The heat released into the room is about the same as three people generate naturally. This means there is no need for the exhaust hose that comes with other portable air conditioners.

Other portable air conditioners with an exhaust hose use four to eight times more electricity and are extremely inefficient.

Why? Most of the cool air is sucked out of the room. The cool air flow is much less than the amount of air sucked out of the room and exhausted through the hose.

Even worse, hot air from outside flows into the room to make up for the air exhausted through the hose, cancelling out much of the cooling.

US Department of Energy Regulations do not yet address new air conditioning technologies like Coolzy. Therefore there are no prescribed tests for energy star ratings. Governments only regulate “energy-thirsty” products sold in large numbers, Since Coolzy is extremely energy-efficient anyway, there is no need for an energy star rating.

In humid conditions, Coolzy extracts water from the cool air giving you that cool, fresh and dry feeling that comes with refrigeration air conditioning. The water evaporates, helping to cool the hot condenser pipes, and comes out with the warm directed to the ceiling. This well-known principle increases the air conditioning efficiency so you get more cooling in humid conditions when you need it most.

In extremely humid environments, some of the water may go into the tray at the back of the unit. An LED indicator will inform the user when to empty the tray.

About 3000 BTU/hr in dry air and 4000 BTU/hr in high humidity.

Other portable air conditioners and split air conditioners provide 12,000 – 24,000 BTU/hr cooling but require 4 – 8 times more electricity.

Coolzy works in any size room as it focuses cooling directly to people, rather than trying to cool the entire room.
