约克YEWS水冷螺杆机组

 

-High efficiency and energy saving, all series have obtained China Energy Conservation Product Certification, and some models have higher COP values ​​than the first energy efficiency level

-Green refrigerant R134a

-Stepless and precise adjustment 12.5%-100%, part load energy efficiency is greatly improved

-York air-conditioning conditions and ice storage conditions, with a wide range of applications

-Large LCD display, easy to operate. Standard RS485 interface, can be connected to building automation system

All connected refrigerant pipes and internal circuits of York Air Conditioning YEWS-D water-cooled chillers have been connected before leaving the factory and can be installed on site at any time. The unit has undergone a high-pressure test, evacuated, and is filled with refrigerant and lubricant by the factory. York Air Conditioning Compressor Each compressor is a direct drive, semi-hermetic twin screw, and includes the following components: It adopts a twin screw rotor and is made of forged steel. The precision-machined cast iron body of the compressor provides the best clearance for the rotor. The design working pressure of the whole compressor is 2.1Mpa. Gauge pressure capacity control: the compressor starts at the minimum load position, and the capacity regulating valve controlled by the microprocessor passes through A continuous-acting spool valve realizes stepless adjustment within the load range of 100%-25%. The spring of the York air conditioning capacity adjustment valve automatically resets to the minimum load position to ensure that the compressor motor starts under the minimum load. The internal exhaust check valve can prevent the rotor from reversing when it stops. The exhaust shut-off valve. Waterproof junction box suction cooling, efficient and reliable The semi-enclosed motor has overload protection: thermistor protection. Compared with direct starting, the star-delta compressor motor starter reduces the starting current to approximately 33%

Features of York Air Conditioning Unit
Oil separator
The compressor has a built-in high-efficiency oil separator, coupled with the condenser's second-stage built-in oil separator, the separation effect is extremely high, which can effectively prevent lubricating oil from entering the refrigeration system and reduce the influence of oil on the heat exchange of the system.
Refrigeration circuit
The pipeline includes: a manual shut-off valve with a filling port, a throttle orifice and a bypass solenoid valve, and a closed-cell foam insulation outside the suction pipe.
Water flow switch: A ram-type water flow switch with a design pressure of 10.3BAR, suitable for chilled water and cooling water pipelines.
Model application example: York central air conditioning in a large hardware factory
