Air conditioning training stand with heat pump EPT/EV

The EPT/EV air conditioning training bench with heat pump provides an opportunity to analyze the operation of an air/water heat pump and the main components of the refrigeration cycle. Students can perform experiments, calculate system efficiency and solve fault diagnosis tasks, gaining practical skills in the field of heating and air conditioning.

The EPT/EV air conditioning training bench with heat pump is designed to provide students with practical knowledge of the operation of an air/water heat pump and its main components, such as the cycle reversal valve and the thermostatic expansion valve. This device also allows for the study of the use of an intermediate fluid to transport heat or cooling energy from the point of production to the point of use.

Main functions and features:

Heat pump performance analysis: allows you to explore the main components and their interactions.
Variable airflow option: through a condenser/evaporator and an air/water heat exchanger, allowing for simulation of various conditions.
Data analysis: the ability to calculate heat exchange, mass flow, theoretical and actual EER and COP, superheat and other important characteristics of the refrigeration system.
Two-cycle scheme: colored hydraulic diagram with LED warning lights, allowing visualization of processes.
