| Abstract: | R134a is currently the most widely used refrigerant, whose problem is the high value of the
global warming potential, and which will have to be replaced in the near future. Thus far, R1234ze(E)
has proven to be the most suitable alternative, but it is slightly flammable. Recently, R1336mzz(E) has
emerged as a possible alternative. During the research, the mentioned refrigerants were compared
with simulations using the Aspen Plus software package in the case of using groundwater as a heat
source. It was found that R1336mzz(E) could be a suitable alternative to R134a since the highest
value of coefficient of performance was obtained using it. However, it must be superheated with an
internal heat exchanger. The problem with using an internal heat exchanger is that the superheating
of the refrigerant vapors affects the isentropic efficiency of the heat pump compressor negatively and,
consequently, lowers the COP value of the heat pump. It has been shown that a one percent decrease
in isentropic efficiency results in a one percent decrease in the COP value. |
