GEOTHERMAL HEAT PUMP EQUIPMENT

KTE-7000GH

Equipment Introduction

This equipment helps to understand the efficiency of burying system of heat exchanger due to Geothermal environment being configured by type of soil heat exchanger, core component of Geothermal system
This equipment generates heat energy by vapor-condensing coolant while maintaining relatively constant temperature all the year round in ground circulating circuit.
It consists of ground circulating circuit and coolant circuit.
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.
It is possible to experience the conversion of heating and cooling operations by using 4-way valve

Equipment characteristics

Test and practice of the 4-way valve control sequence circuit
Test on forced geothermal heat pump using artificial ground
Education on the structure and principle of heat pump using geothermal
Cooling cycle :

Compressor → Reversing Valve (4 way valve) → Geothermal system → Check valve 2 → Receiver → Filter dryer → Sight glass → Solenoid Valve → Manual expansion valve 1 → Heat exchanger 1 → Accumulator → Compressor

Heating cycle :

Compressor → Reversing Valve (4 way valve) → Heat exchanger 1 → Check valve 1 → Receiver → Filter dryer → Sight glass → Solenoid Valve → Manual expansion valve 2 → Geothermal system → Accumulator → Compressor
