  1. Evaporator
  2. Compressor unit
  3. Condenser unit
  4. Internal heat exchanger
  5. Ekspansion valve
  6. Drying filter

1. Evaporator

Larger heat exchanger and heat exchange surface compared to the low-temperature Terragor heat pump.

2. Compressor unit

A special heating compressor with extra refrigerant injection into the compressor head.

3. Condenser unit

Efficient transfer of thermal energy:

  • Flexible panel geometry;
  • Optimization of asymmetry of distribution channels;
  • Low flow resistance on the water side of the heat exchanger;
  • Larger heat exchanger and heat exchange surface compared to the low-temperature Terragor heat pump.

4. Internal heat exchanger

Returns the energy that would be dissipated into the environment, back to the cooling system. Protects the compressor from influx of liquid refrigerant.

5. Exspansion valve

Expansion valve reduces the refrigerant temperature and pressure to a level at which it can evaporate and enter the evaporator unit.

6. Drying filter

Drying filter is an element of the cooling system intended for eliminating water from the refrigerant in order to prevent corrosion of system elements.
