INTRODUCTION TO AEROTHERMY

Aerothermal is the technology by which we extract thermal energy from the air to heat it. We do this extraction and use by means of heat pumps, with them we obtain considerable economic savings and support for nature conservation. This saving is determined because of the total energy used, a part comes from the air and the rest comes from the production of the pump itself. The part taken from the air is free.

To understand this, it is convenient to know the following terms: COP-EER-SCOP-SEER C.O.P: COEFFICIENT OF PERFORMACE E.E.R: ENERGY EFFICIENCY RATIO SEER: SEASONAL ENERGY EFFICIENCY RATIO SCOP: SEASONAL COEFFICIENT OF PERFORMANCE C.O.P: HEATING POWER / EXPENDED ELECTRICAL POWER EER: REFRIGERATING POWER / EXPENDED ELECTRICAL POTENTIAL SCOP: IS AN AVERAGE COP OF THE COP IN DIFFERENT CIRCUMSTANCES SEER: IS AN AVERAGE EER OF THE EER IN DIFFERENT CIRCUMSTANCES The heat pumps can be grouped by: THEIR CONSTRUCTION: Monobloc, Bibloque YOUR USE OR APPLICATION:

• For A.C.S and heating
• For pools - For underfloor heating

HEAT PUMP

It is a machine (thermal machine) that extracts heat from a cold environment and brings it to a warmer environment, that is, doing work. This is the basic idea or the principle, but to do it we will have to follow the following path:

EVAPORATOR It is in charge of carrying out a change of state, from liquid to gaseous. This change occurs in the coolant.

THE CONDENSER It takes care of removing the heat from the liquid refrigerant, which will be transferred to a fluid or air (direct expansion.) The refrigerant goes from the gaseous state to the liquid, therefore, there is a heat exchange. We have two phases, one the cooling of the refrigerant gas and the other the condensation of the gas, transforming it into a liquid.

THE COMPRESSOR Here the gas, which comes from the evaporator, is compressed in the gaseous state, increasing its pressure, to pass to the condenser.

THE EXPANSION VALVE This valve regulates the circulation of the refrigerant according to the pressure that it needs to be cooled as it passes through the evaporator.
