heat pump of air split-conditioner

Today, in air conditioning and heating systems for small rooms of industrial, public, and residential buildings, the use of heat pumps of air split-conditioners is becoming more common.  However, heat pumps of air split-conditioners are energy-intensive equipment, and, therefore, the need to increase their energy efficiency arises.  It is important to reduce energy consumption during the refrigeration machines operating in the mode of heat pump in air split-conditioners, which is possible using a modern method of thermodynamics — an exergetic one.  Exergetic an

Nowadays, the use of heat pumps (HP) of air split-conditioners in air conditioning and heating systems of small industrial, public and residential facilities is becoming more common.  It is known that the nominal heat capacity of HP of air split-conditioners is given in catalogs or reference literature under standard outdoor temperature conditions, namely: outdoor air temperature $+7\,{}^\circ$C, indoor air temperature $+21\,{}^\circ$C.  At the same time, manufacturers of air split-conditioners do not ensure that, regardless of the size of heating capacity, all air spli
