Design and Development of a Didactic and Research Stand for Exploitation Tests Under Defined Conditions
Part of the Springer Proceedings in Energy book series (SPE)
To develop the laboratory of renewable energy sources in Miękinia, a new stand with a heat pump was created. The main aim of this stand is to increase the range of research in the Laboratory. This stand consists of:
This creates opportunities for research about the efficiency of heat pumps in reference to present standard PN EN 14511 and previous standard PN EN 255. The data allows us to define the impact of the methodology described in the standards on the coefficient of performance. This stand is able to calculate the coefficient of performance according to set parameters of work, like temperature of heat source, temperature of heat sink or difference between inlet temperature and outlet temperature on the heat sink side. There is also research about the effect of the superheating of refrigerant on the efficiency of heat pumps. All of the research with this stand is intended to examine the efficiency of heat pumps. This stand was also made for didactic purposes. It has the possibility to show the following, how the heat pump works, how the refrigerant circulates inside the heat pump, and what happened with the refrigerant in elements of a heat pump like a compressor, evaporator, condenser, expansion valve. There is also the possibility to show the dependence between the coefficient of efficiency and the temperature of the heat source or heat sink.
a heat pump module,
a module to simulate the parameters of the heat source and heat sink,
a module to display and register data and a remote control.
