First, the unit profile:
Ultra-low temperature air source heat pump unit using jet enthalpy technology, making a single press to achieve the effect of two compression, efficient, energy saving. -25 ℃ low temperature environment, stable operation of heating, the maximum water temperature can be above 60 ℃, operating costs than traditional heating mode to save more than 70%, low carbon, environmental protection, as the preferred boiler coal-fired heating the preferred model. Compared with the conventional air-cooled module, the unit is not only a wide range of operation, the cooling and heating efficiency ratio are effectively improved, especially in low temperature heating COP can be increased by more than 20%.
Units to a wide range of operation, efficient and stable operation characteristics, widely used in hotels, bath centers, hotels, office buildings, hospitals and other places. Unit load side is a diversified features, can be radiator, fan coil, floor heating and so on.
Second, the unit features:
Equipped with a jet enthalpy technology of air-cooled module unit, the scope of coverage of more than 95% of China's region, the maximum degree of user satisfaction with the unit efficiency, comfort, safety requirements. Unit innovation The traditional central heating method is the ideal product to replace the boiler. Guide the new energy-saving emission reduction, to the user to bring specific convenience and benefits, and effectively protect the global environment. Particularly suitable for the northern region, in low ambient temperature need to heat the place.
■ more cooling capacity
The unit will be used in the refrigeration system by adding the enthalpy technology to the refrigeration system. The heat capacity of the unit can be improved by the action of the economizer, so that the cooling capacity of the whole machine can be greatly improved, and the capacity can be increased by more than 12%.
■ low ambient temperature strong heating
Unit in the low ambient temperature of the heating capacity has been greatly improved, low temperature heating design environment temperature of -15 ℃, the maximum working environment temperature up to -25 ℃. Jet enthalpy technology in the heating application, the heat can be increased by more than 30%, energy efficiency can be increased by more than 20%;
■ reliable operation, low carbon environmental protection
Unit testing center through the CNAS national test room certification, rigorous testing of the unit, so that the quality of each factory unit to be a reliable guarantee. Unit life of up to 15 years, not affected by the environment, all seasons are used. In the ambient temperature -25 ℃ ~ 43 ℃ between the all-weather operation.
The unit in the northern region as a heating equipment in winter, whether it is sulfur dioxide, carbon oxides, and carbon, ammonia emissions are "0". Reduce the pollution of the atmosphere, protect the environment, according to customer requirements, at any time can be heating, energy saving more comfortable. In line with the national energy-saving technology to promote the direction of innovation in the traditional way of heating.
■ precise control, simple operation
Industrial-grade microcomputer controller, advanced control, full-featured, protection unit continued stable operation, LCD display, menu operation, user-friendly, easy to use.
Inter-module network control through RS485 communication interface to each other. Through a display interface for each module control, data and operating status monitoring, the number of modules to choose.
The operation of each module is relatively independent, centralized control; multiple protection function to ensure the safe operation of the unit.
■ user-oriented, custom diversity
According to the user region and the use of different, the module unit is divided into two series D1 and D2:
D1 series, the maximum heating water temperature up to 50 ℃ or more, low temperature heating water temperature up to 45 ℃.
D2 series, the maximum heating temperature of up to 60 ℃, low temperature heating water temperature up to 55 ℃ or more.
D1 series of heating conditions Operating range:

Suitable for refrigerant, R22, R410A, exhaust temperature should be less than 115 ℃
D2 series of heating operation range:

Suitable for refrigerant, R22, R407C, exhaust temperature should be less than 115 ℃
