Air Cooled Screw Chiller Crew Details
- Oct 24, 2017 -

Its key components of air-cooled screw chiller - Screw compressors employed air-cooled screw chiller named, out of the evaporator unit by the state of the refrigerant gas; adiabatically compressed by the compressor after, a high temperature high-pressure state. Compressed gas refrigerant, in the condenser, isostatic cooling condensation, after condensation into liquid refrigerant, and then through the throttle valve to low pressure, into a gas-liquid mixture. Which low temperature and low pressure liquid refrigerant, in the evaporator to absorb the heat of cold matter, re-become gaseous refrigerant. The gaseous refrigerant is reintroduced into the compressor via the pipe to start a new cycle. This is the four cycles of the refrigeration cycle. It is also the main working principle of the screw chiller

Vertical equipment composition views Results words views Results Results

1, the use of international brands compressor, the new high efficiency spiral rotor compressor, compressor performance than the average 20% -30% higher, and access to Europe and the United States multi-national patent IS9001 international quality certification.

2, high efficiency 5: 6 patent asymmetric rotor tooth profile.

3, capacity control can be used four-stage (100% -75% -50% -25%) or three (100% -66% -33%) and no-stage control system.

4, the use of 11 bearings and a axial thrust balance drum combination design, a substantial increase in bearing life 2.5-3.5 times.

5, the use of high efficiency silicon steel special slot design, and equipped with internal and external design of the cooling channel, so that the compressor motor can play under any load the highest efficiency.

6, a unique built-in hydraulic system, no oil pump to ensure that the compressor to maintain the best lubrication effect Oil separator with double filter, filter effect is good, heat exchanger can play the maximum capacity.

7, high efficiency, low noise, low vibration.

8, a variety of refrigerants to choose from, in addition to R22 refrigerant, you can also use R134a, R407c and other environmentally friendly refrigerant.

9, the full range of compressor volume ratio (VI = 2.2 / 2.6 / 3.0 / 3.5) can be effectively avoided due to over-compression or compression caused by the additional energy consumption

Air-cooled screw chillers Details:

In addition to the general characteristics of the unit in the assembly performance of the water-cooled screw unit, the biggest advantage is that there is no need for a water cooling system, as long as it is a good place to use.

Air-cooled screw chillers do not need to be equipped with cooling water pumps, cooling towers and other auxiliary equipment, can save a lot of material and engineering installation costs, or even need to set the engine room.

Units can be widely used in hotels, restaurants, shopping malls, schools, hospitals, offices and other industrial and civil construction environment air conditioning system.

In addition to stereotypes products, the company can also be customized according to customer requirements of all kinds of special chillers and heat pump units, and provide on-site assembly, technical guidance and on-site commissioning services

Air-cooled screw chiller for the fin-type, the use of dual-oil ripple hydrophilic aluminum platinum, made by a professional heat exchanger processing equipment, with a compact, small size, light weight, high efficiency of heat transfer, and Configuration of low-speed large-axis axial fan, can effectively reduce the running noise, reduce the impact on the surrounding environment.

Air-cooled screw chiller unit control system using imported PLC program controller, man-machine interface configuration large screen touch screen, the interface is simple and generous, intuitive and easy operation.

Screw air chiller unit has a reliable safety protection device, comprising: high and low pressure protection, overheating protection exhaust gas, the compressor motor overheating protection, overcurrent protection, temperature frost protection, water protection, an emergency stop Switches, temperature-type easy to fuse, such as safety valve
