Air cooled screw high efficiency five- functional unit Details

◆High efficiency and energy saving

The high-efficiency internally threaded copper tube and aluminum louver spoiler are used to make the copper tube and the aluminum sheet tightly joined by mechanical expansion tube to give full play to the best heat transfer effect. The total heat transfer coefficient is 67% higher than that of ordinary coils. Aluminum The slices are treated with hydrophilic and anticorrosive treatment, which can effectively reduce the thickness of the condensed water film during heating operation, reduce the thermal resistance of the water film, and improve the heat transfer efficiency of the coil. Both the evaporator and the condensing coil have higher heat transfer efficiency to increase The cooling (heating) capacity of the unit reduces the input power.

The unit capacity can be intelligently adjusted according to the load condition to match the operating capacity with the actual load, so as to improve the compressor's work efficiency and reduce power consumption.

Using self-adjusting intelligent defrost mode, defrost is accurate and effective to avoid heat loss.

The use of the latest internally threaded high-efficiency heat exchange tube, the heat transfer coefficient is 1.3 times that of the ordinary high-efficiency heat exchange tube, and the evaporation and condensation in the tube have high heat transfer efficiency to ensure good cooling and heating performance of the unit.

In the cooling + water mode, the unit can provide cold water while providing free hot water without cooling towers, which greatly improves the energy utilization rate and is economical and reliable in operation. The overall energy efficiency ratio of the unit is equivalent to that of a water-cooled unit, which is much higher than that of an air-cooled unit. The heat pump unit is an energy-saving operation mode.

The unit has multiple functions, one machine with multiple functions, saving investment, reliable and flexible control. The perfect combination of air conditioning and domestic hot water is realized, and it has the dual advantages of hot water and air conditioning. According to customers' needs, the unit can provide multiple operation modes such as cooling, heating, cooling + hot water, etc.

●Intelligent defrosting system

The unit adopts the intelligent reverse cycle defrosting method, the defrosting is thorough, and the defrosting time is short. At the same time, adaptive technology is adopted, which can automatically correct and adjust the conditions and parameters of the next defrost according to conditions such as the ambient temperature and the last defrost time.

◆Reliable performance

Using ALCO, SPORLAN, DANFOSS, SAGINOMIYA and other well-known European and American brand refrigerant system components, the quality is stable.

The electrical components are all well-known brands such as SIEMENS, SCHNEIDER, ABB, LS, etc., with reliable performance.

The unit is equipped with a variety of protection devices such as high and low pressure, antifreeze, oil temperature, oil level, overload, internal overheating, and underphase inversion to ensure the safe operation of the unit.

The condensing fan adopts a step-by-step air volume control system, and the unit operates normally at 15~45℃ during cooling and -10~21℃ when heating.

◆Control system

The local networking can be realized through a simple communication line connection.

Automatic fault diagnosis and protection. Operation and energy management functions.

Chinese character menu and triple password.

Remote monitoring.

◆Simple installation and convenient maintenance

The unit has been filled with refrigerating oil and refrigerant before leaving the factory, and has been debugged and tested in accordance with national standards and corresponding factory standards. The site only needs to connect the water pipe and the power source to put it into operation.
To provide users with chilled water and hot water. Unit automatic control system; automatic fault diagnosis and protection, operation and energy management functions.

◆Low noise

It adopts semi-hermetic screw compressor, stable and reliable operation, low noise and vibration.

The unit adopts a low-speed and low-noise axial flow fan with high fan efficiency.

The compressor uses a sound insulation device to insulate noise (optional accessory).
