Ultra low temperature air source heat pump

Introduction to ultra-low temperature air-cooled module unit:

The ultra-low temperature air-cooled module unit adopts jet enthalpy increasing technology, which enables a single compressor to achieve two-stage compression effect, high efficiency and energy saving.-20Stable heating operation under low temperature environment of ℃, with a maximum effluent temperature of up to60Above ℃, the operating cost is saved compared to traditional heating methods70%Above all, low-carbon and environmentally friendly have become the preferred models to replace coal-fired boilers for heating. Compared with conventional air-cooled modules, this unit not only has a wide operating range, but also effectively improves the efficiency ratio of refrigeration and heating, especially in low-temperature heating environmentsCOPCan be improved20%above.

The unit is widely used in hotels, bath centers, guesthouses, office buildings, hospitals and other places with a wide operating range and efficient and stable operating characteristics. The load side of the unit has diversified characteristics, such as radiators, fan coil units, floor heating, etc.

Characteristics of ultra-low temperature air-cooled module unit:

Air cooled module unit equipped with jet enthalpy increasing technology, applicable to China95%The above areas maximize the satisfaction of users' requirements for unit efficiency, comfort, and safety. The unit innovates the traditional centralized heating method and is an ideal product to replace boilers. Guiding the new direction of energy conservation and emission reduction, bringing specific convenience and benefits to users, and effectively protecting the earth's environment. Especially suitable for northern regions where heating is required at low ambient temperatures.

■Stronger cooling capacity

The unit applies jet enthalpy increasing technology to the refrigeration system, which improves the heat exchange of the unit through the effect of an economizer, greatly enhancing the refrigeration capacity of the entire machine, up to a maximum of12%The above abilities.

■Efficient heating at low ambient temperatures

The heating capacity of the unit has been greatly improved at low ambient temperatures, and the design ambient temperature for low-temperature heating is-15℃, the maximum working environment temperature can reach-20℃. Jet enthalpy increasing technology can increase the heating capacity in heating applications30%Above, the energy efficiency ratio can be improved20%above;

■Reliable operation, low-carbon and environmentally friendly

The unit testing center has passedCNASNational level testing laboratory certification, strict testing of units, ensuring reliable quality assurance for each factory unit. The unit has a service life of up to fifteen years, is not affected by the environment, and can be used all year round. At ambient temperature-20℃～-43It can operate 24/7 between ℃.

When the unit is used as a heating equipment in winter in northern regions, its emissions of sulfur dioxide, carbon oxides, as well as carbon and ammonia are all“0”. Reduce air pollution, protect the environment, provide heating at any time according to customer requirements, save energy and make it more comfortable. In line with the promotion direction of national energy-saving technology, innovate traditional heating methods.

Accurate control and simple operation

Industrial grade microcomputer controller, advanced control, comprehensive functions, ensuring continuous and stable operation of the unit, LCD display, menu operation, user-friendly interface, easy to use.

The networking control between modules is achieved throughRS485Connect communication interfaces to each other. Control, monitor data and operating status of each module, and select the number of modules through a display interface.

The operation of each module is relatively independent and centrally controlled; Multiple protection functions ensure the safe operation of the unit.

Targeting users, customizing diversified options

According to different user regions and purposes, this module unit is divided intoD1andD2Two series:

D1Series, the maximum outlet temperature for heating can reach50Above ℃, the outlet temperature of low-temperature heating can reach 45 ℃.
