The advantages of Dannice's design

Falling film variable frequency screw refrigeration unit with large refrigeration capacity, environmentally friendly refrigerant, semi enclosed single machine dual stage variable frequency screw compressor, dual head, falling film shell tube dry evaporator, shell tube condenser, oil distribution separator, with frequency converter control, including control box, inlet and outlet temperature of 12 ℃/7 ℃, adjustable chilled water temperature range of 5 ℃~35 ℃, and cooling water inlet and outlet temperature of 32 ℃/37 ℃. Paired with square countercurrent cooling tower, chilled water circulation pump, cooling water circulation pump, etc.

(1) The compressor adopts an internationally renowned brand semi enclosed single stage dual stage variable frequency screw compressor, with variable frequency starting and control;

(2) Efficient falling film shell and tube evaporator, shell and tube condenser;

(3) Adopting a microcomputer control system, combined with a large screen LCD display, to continuously monitor the operation of the unit in real-time, displaying the operating status of the unit (inlet/outlet temperature, cumulative operating time, unit capacity, etc.) and fault information, providing a safe and effective method for troubleshooting; It can achieve interlocking control with chilled water pumps, cooling water pumps, cooling towers, and water system valves, and monitor the reliable operation of the water system; Equipped with multiple safety protections (phase sequence protection, compressor high and low pressure protection, overload protection, motor overheat protection, exhaust temperature high protection, oil pressure difference high protection, water flow insufficient protection, antifreeze protection, etc.) and fault diagnosis functions (temperature sensor fault alarm, cooling tower fan overload alarm, water pump fault alarm, etc.), comprehensively protecting the operation of the unit system, maximizing the energy efficiency and reliability of the unit; Equipped with a standard RS485 interface and supporting Modbus communication protocol, it is convenient for the unit to access the upper computer monitoring system and achieve remote centralized monitoring.
