■Technical Description
1. This equipment generates heat energy by vapor-condensing coolant while maintaining relatively constant temperature all the year round in ground circulating circuit.
2. It consists of ground circulating circuit and coolant circuit.
3. It is designed for test and practice on the composition of the system based on the conventional vapor-compression cooling cycle and various basic automatic controls.
4. It is also possible to experience the conversion of heating and cooling operations using heat pump system.
5. It is possible to switch between ground and water as heat source.

 ■Experiments(Study objectives)
- Test and practice of heat pump
