Abstract :
Paper deals with calculation and design of the heat pumps that are used for purposes of heating and cooling. Heat pumps are systems that draw heat from one source (earth, water, air or ambient) and transfer it to another. Their operation is described by Carnot circular process, in which thermal energy is taken from one body to working medium and then from a working medium to the heated body. Energy put in the process is equal to the energy needed for moving and compression of the working medium. Authors have calculated that average energy input is equal to ¼ of useful thermal energy (output). Further on in the paper the working principle of the heat pumps and their main parts are described.
