Coolerado Indirect Evaporative Air Conditioning
The Coolerado air conditioner uses a thermodynamic cycle called the Maisotsenko Cycle
(M-Cycle) that capitalizes on natural, clean energy – psychometric energy – found in our atmosphere. This cycle can improve any energetic or refrigeration cycle.
The patented Coolerado heat and mass exchanger was developed to economically take advantage of the M-Cycle. A heat and mass exchanger (HMX) consists of several plates of a special plastic that is designed to wick water evenly on one side and transfer heat through the other side. The plates are stacked on each other, separated by channel guides.
The purpose of the channel guides is to provide structure to the exchanger as well as direct air movement within the HMX. The channel guides divide the incoming air stream into product air and working air. The product air is always separate from the working air and stays within dry channels the entire length of the exchanger. The product air is cooled sensibly (rejecting its heat to the working air), and can be designed to cool below the wet bulb temperature of the incoming air stream. The product air travels the distance of the exchanger and into the space designated for cooling.
The working air initially enters dry channels where it is pre-cooled sensibly before it is fractioned into multiple streams which are directed into wet channels. The heat from the product air is transferred to the working air in the wet channels by means of evaporation (mass transfer and state change). The heat is exhausted out the sides of the HMX and then to the atmosphere.
Because the heat from the product air is rejected to the working air through heat exchange surfaces in the exchanger, the product air only experiences sensible cooling – cooling without adding humidity. The product air stream is completely separate from the working air and never comes in contact with a wetted surface. This process occurs multiple times in a short physical space within the exchanger, resulting in progressively colder product and working air temperatures.
