K&H KR-115
Refrigeration Cycle and Heat Pump System

Refrigeration Cycle and Heat Pump System is designed for learning the theories of heat transfer in refrigeration engineering


Refrigeration Cycle and Heat Pump System

Apart from the 4 major components, the auxiliary devices such as refrigerant receivers, refrigeration accumulators and filter, are mounted components on the front panel for direct operation and observation

KR-115 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.

System Features

  • Providing a control panel to switch between cooling and heating.
  • Providing 6 sight glasses to observe the refrigerant status before and after passing through the evaporator, the condenser, the expansion devices, and the compressor.
  • Providing 5 hand valves to control the flowing direction of the refrigerant.
  • Providing high and low-pressure protection switches to automatically halt the compressor when detecting incorrect
  • refrigerant flowing paths
