Systems based on Maisotsenko cycle : Coolerado coolers

Abstract

A large part of the world's energy is consumed by ventilation and air-conditioning. One of the most energy-intensive processes in the ventilation and air-conditioning is the process of air cooling. Tradi-tional systems based on the compressor cycle consume a lot of energy. Refrigerants contained in com-pressor circuits are often very harmful to the environment. These factors led to the active development of evaporative coolers. And the former soviet scientist Valery Maisotsenko improved evaporative cooling technology and called the resulting cycle as Maisotsenko-cycle (=M-cycle). He also patented a series of devices based on the M-cycle. Some of the devices based on the M-cycle are Coolerado air conditioners. These air conditioners have very low power consumption and the ability to cool the air below the wet bulb temperature.

The aims of this work are: to get acquainted and understand principles of the M-cycle and review the systems from different areas based on the M-cycle; to figure out the advantages of the Coolerado air-conditioners compared to traditional evaporation and compressor systems and to calculate the possi-bility of using Coolerado air conditioners in Scandinavian climate.

In order to reach specified aims the following methods are applied: literature review, analysis of dif-ferences between traditional adiabatic cooling systems and evaporative systems based on M-cycle and calculation of the possible use of this system in Scandinavian climate.

This thesis describes principles of the M-cycle and systems based on it. In this work advantages and disadvantages of the Coolerado coolers are figured out and compared to the traditional cooling systems. Also the possibility of use of Coolerado coolers in Northern climate is estimated.
