With the evolution on thermal comfort solutions, the need to study heat-pumps and refrigeration systems has increased. This means that there's an interest in developed apparatus that will allow to converge the refrigeration cycles theory with the practical application of theses cycles. This equipment has been designed taking into account the basic principles of thermodynamics, namely the second law of thermodynamics. Some study cases performed on this equipment allow to demonstrate the capability to use this type of apparatus in teaching or practical situations.
