Blue Dolphin -- Two-Stage High-Temperature Heat Pump

The Lanhai Dolphin two-stage high-temperature heat pump can reach an outlet water temperature of 80℃, directly replacing traditional coal-fired, oil-fired, and electric boilers. It is suitable for room heating and domestic hot water supply in high-altitude areas and can also be used in bathhouses, saunas, factories, homes, and commercial settings.

Integrated double-layer structure design, excellent craftsmanship , The unit's condensate water and rainwater are completely isolated from the compressor system components, preventing water damage and rust. , Long service life, compressor operation noise is completely isolated, inner side full honeycomb sound insulation cotton design, quieter, unit protection is safer. Environmentally friendly and energy-efficient design, use R410a and R134a environmentally friendly refrigerant, no pollution. Using a high-efficiency scroll compressor, German GEA high-efficiency plate heat exchanger, two-stage design technology, the unit's low-temperature heating performance is excellent , Stable and reliable.

Working principle :

During operation, the system 1 (R410a refrigerant ) evaporator evaporates the refrigerant to absorb heat, then the compressor and throttle valve send the heat-absorbed refrigerant to the system 1 condenser, transferring the heat to the system through the plate heat exchanger 2 (R134a refrigerant ) evaporator, finally the system 2 compressor and throttle valve send the heat to the system 2 condenser, ultimately heating the water. Strong heating type with high outlet water temperature, no need to use backup electric heating. Outlet water temperature can reach 80 ° C 。
