Analysis of the current state of room cooling systems

Abstract

The paper investigated alternative types of climate formation systems based on such types of cooling systems as: adiabatic cooling; cold ceiling; absorption refrigeration machine using lithium bromide; system using the Peltier element. A scheme is proposed and developed, which takes into account the shortcomings of the considered systems. The proposed system has a simple design, more environmentally friendly, it has no refrigerant. The number of Peltier elements required for the formation of a given temperature in the room is calculated. The development of alternative cooling systems is a very important issue today. In residential areas, there is a widespread demand for air conditioners using freon as a refrigerant. These systems are not reliable due to the risk of freon leakage. There is also a problem that the air conditioner is a source of high humidity, which in turn causes the growth of bacteria and fungi. Along with the tightening of sanitary requirements for living quarters and living quarters and bans on the use of old varieties of CFCs, scientists and manufacturers have been forced to look for new, more environmentally friendly types of refrigeration without the use of CFCs. These include: the use of water and its solutions as refrigerants; use of the difference of ambient temperatures; heat pumps based on the Peltier effect.

As a result of research it was found that it is better to use the Peltier element to cool the room, as it is environmentally friendly (no emissions of CO2, CO, CFH3, CFClH2), no mechanical parts. To cool a room of 10 m2 requires about 8 pcs. It is better to use accurate temperature sensors for precise system control.

The obtained data are useful and important: it is proved that the system using the Peltier element can work on cold generation; The proposed calculations are universal because it has the ability to calculate the power of Peltier elements. The use of the Peltier element will allow you to use the power of the sun to reduce the negative effects on humans, in particular the effects of high temperatures.
