This heat pump is EVI heat pumps for extreme cold area, working ambient from -35-50℃
For a hotel. triple function of heating, cooling and domestic hotel hot water.
Equiped with 5 sets of air source heat pump, cover 100 rooms usage
This ultra-low temperature air energy heat pump unit and its use method provide an ultra-low temperature air energy heat pump unit and its use method with simple structure, automatic defrosting of the condenser, good defrosting effect, and energy saving. The air energy heat pump unit in the technology can not defrost normally under the ultra-low temperature, and the defrosting effect is poor. In severe cases, the air energy heat pump water heater or heating air conditioner cannot work normally and other technical problems. It passes on the condenser of the device. Condenser sensor and several sets of heating fins are installed. The heating fins are parallel to the condenser fins and fixed on the copper tube of the condenser. The water temperature sensor, compressor, heating fin, condenser sensor and water temperature sensor are installed in the water tank. The controller is connected to an external power supply, and the controller automatically controls the switching of the heating fins according to the temperature values measured by the condenser sensor and the water temperature sensor.
