Principle

OA-TCS series unit is a cold and hot water unit using the principle of water source heat pump, the use of rivers and sea water as a cold and hot source, in summer cooling, the unit provides 7℃ cold water for cooling in the cabin; In winter heating, the unit provides 45℃ hot water for cabin heating.

Characteristic

• Modular design: The water system can be realized in parallel, easy to combine, to achieve large cooling capacity/heat demand, increase the regulation performance, reduce the starting current

• Rivers and sea water side adopts detachable combined coaxial tube heat exchanger, which is convenient for water side cleaning and maintenance

•3℃ low water temperature, heating capacity to reach more than 70% of the rated

• Imported brand fully enclosed compressor, low noise

• Digital control, complete protection

• Anti-corrosion, anti-vibration and anti-shaking design

• Modular frame structure, can be horizontal or vertical parallel, suitable for different space requirements

Protection function

• Water flow protection: seawater and circulating water lack and cut off water

• Refrigerant pressure protection: high and low pressure

• Compressor protection: overload and overheating

• Water temperature protection: Low water temperature and temperature difference between incoming and outgoing water

   Circulating water high and low water temperature, inlet and outlet water temperature difference

• Optional: zinc rod corrosion protection
