Refrigeration Cycle & Heat Pump System


This trainer designed to learn the theory of Heat Transfer in refrigeration engineering.  With proper setup, KR-115 can be emulated as a Refrigeration or Heat Pump system.  All system components are mounted on the front panel so students can directly observe, touch the components, and hear the noise produced by the components while it is running under either Refrigeration or Heat Pump cycle.  It offers three expansion devices available for the refrigerant to pass through; they are pressure expansion valve, capillary tube, and thermal expansion valve. Students can use the control panel to switch the preferred expanding path from three expansion devices and compare the corresponding performance under Refrigeration or Heat Pump cycle.
