ESPA double-stage high-temperature heat pump, with a water outlet temperature of 80 ° C, can directly replace traditional coal-fired boilers, oil-fired boilers, and electric boilers. It is suitable for heating and living hot water supply in rooms in high and cold areas, and can also be used in baths and saunas , Factories, homes, businesses, etc.

Integral double-layer structure design, sophisticated technology, the unit's condensate and rainwater are completely isolated from the compressor system components, not easy to soak water and rust, long service life, the compressor's operating noise is completely isolated, the inner honeycomb sound insulation cotton design, more quiet, the unit Protection is safer. Environmental protection and energy efficient design, using R410a and R134a environmentally friendly refrigerants, no pollution. Using high-efficiency scroll compressor, German GEA high-efficiency plate heat exchanger, two-stage design technology, the unit has excellent low-temperature heating performance, stability and reliability.

working principle

When working, the evaporator of system 1 (R410a refrigerant) evaporates the refrigerant to absorb heat, and then sends the heat-absorbed refrigerant to the condenser of system 1 through the compressor and the throttle, and sends the heat to system 2 through the plate heat exchanger. (R134a refrigerant) evaporator, finally there is a system 2 compressor and throttle to send heat to the condenser of system 2, and finally heat the water. The high heat type has a high water outlet temperature, and there is no need to use standby electric heating. The outlet temperature can reach 80 ° C.
