Product Description

Air-cooled Screw Chiller

Product Overview
This series of unit is a kind of refrigeration equipment with screw compressor as the core and air as the coolingmedium. it does not need to rely on the cooling water system (e.g. cooling tower), and realizes the refrigeration cycleby forcing air convection to cool the condenser through the fan. The refrigerant (e.g. R22, R134a, R410A etc.exchanges heat directly with air in the condenser, eliminating the need for water treatment in water-cooled units.This series of units are characterized by reasonable structure, easy operation, reliable operation, high energyefficiency, low noise and easy installation and maintenance. lt can be used as the cooling and heating source oicomfort air-conditioning systems in shopping malls, residences, ofhce buildings, commercial buildings, factoryworkshops, hotels, hospitals and other types of buildings and facilities
Product Features
Easy to install
All the units are assembled in the factory and shipped after strict operation and debugging, and the on-siteinstallation only requires the connection of power supply and water system piping, and then it can be operated.Space-savingThis series of units can be directly installed on the roof of the building, podium, courtyard or horizontal groundwithout the need to set up another machine room.
Cost saving
The unit adopts air circulation heat dissipation method, simple water system, convenient management andmaintenance, especially suitable for places where cooling tower cannot be installed or water is scarce.
Easy operationThe unit adopts microcomputer control, can be operated directly through the panel or remote control startComputer controller interface is simple, full Chinese display, easy to operate. The panel can display the operatingstatus of the unit, operating data and fault alarm status
High energy effciency, low noise
The unit adopts high-efhciency semi-closed double-screw compressor, brand-name condensing fan andhigh-quality refrigeration accessories, and after careful optimization of the design and assembly as well as rigoroustesting, the unit has the characteristics of low operating noise, low vibration and high reliability.No need to install cooling towei
Saving cooling tower, cooling system water pipesystem material cost, installation cost, operation cost andmaintenance cost.

 Introduction to main components of unit

Compressor

Adopting twin-screw (male and female rotor) structure, divided intosingle screw and twin screw, compressing refrigerant by rotary motionSmooth running, low noise, long life, suitable for large cooling capacitydemand.
Condenser
The fnned tube heat exchanger adopts seamless purple copper tubesand special aluminum fns with secondary stamping and flangingtechnology and double corrugated sheet type, and the copper tubesand fns are tightly bonded by the mechanical upturning of the tubes toachieve the best heat exchange effect.

Evaporator

Shell and tube or plate heat exchanger: The refrigerant evaporates inside the tubes and absorbs the heat from thechiled water outside the tubes to achieve refrigeration. The chilled water side is usually designed as a closed loorfor use at the user end (e.g. air conditioning end or process cooling).
Throttling Devices
Thermal Expansion Valve (TXV) or Electronic Expansion Valve (EXV): Controls the refrigerant flow, regulates theevaporator liquid supply and ensures effcient heat transfer. Electronic expansion valves are more precise and canbe used with intelligent control systems to optimize energy effciency.
Microcomputer Controller
Monitor pressure, temperature, current and other parameters torealize automatic start-stop, load regulation, fault protection (such ashigh and low pressure protection, overload protection).

Water-cooled Screw Chiller

Product Overview

This series of unit is a kind of central air-conditioning refrigeration equipment with screw compressor as thecore and water as the cooling medium. its working principle is that the refrigerant is compressed intohigh-temperature and high-pressure gas by screw compressor, and then cooled to liquid state by condense(water-cooled), and then throttled down throuah the expansion valve and fnaly absorbed the heat of chilled watein evaporator to realize the purpose of refrigeration.
This chiller unit is widely used in commercial buildings, industrial plants, data centers, hospitals and other felds

Product Features

Easy to install
Modularized design: the whole machine is pre-installed at the factory, only the chilled water pipe and powelsupplyneed to be connected, and the installation cycle is short.
Small footprint: no need for cooling tower and water pump room, suitable for roof or outdoor platform with limited space.

High energy efhciency

Excellent part-load performance and low-temperature adaptabilityLow maintenance costNo water treatment: no cooling water system, eliminating the need for water t reatment, pipe cleaning and othermaintenance work.
Long life design:

simple structure of screw compressor, long maintenance cycle.Reliability and silent design
Multi-protection:

 All-round protection for high pressure, low pressure, oil pressure, motor overheating, etc.
Low noise optimization:

 low noise fan and compressor soundproof cover are adopted.

Main Components

Compressor:

twin-screw or single-screw design, stable operation and long life.

Water-cooled condenser : through the cooling water (such as cooling tower circulating water) to take away the heat, the effciencyis higher than air-cooled.

Evaporator : heat exchange with chilled water, output low temperature chilled water.

Microcomputer controller : adopts large touch screen, with powerful control function and many other functionssuch as fault self-diagnosis.

Water-cooled Scroll Chiller

Product Overview
This series of unit is is a kind of high-effciency, energy*saving refrigeration equipment, the core of which adoptsscroll compressor technology, combined with water-cooled heat exchange.

This chiller unit is widely used in small and medium-sized commercial buildings (such as hotels, shopping mallsoffce buildings), industrial equipment cooling (such as injection molding machines, laser equipment), and placesthat require year-round cooling (data centers, laboratories).

Main components

Main components

High energy effciency

High volumetric effciency of scroll compressor, excellent part-load perfommance; Water-cooled heat dissipationeffciencyis better than air-cooled, lower condensing temperature.

Stable and reliable

Scroll compressor has less moving pats, less wear and tear, long service life; water-cooled system is less affectedby ambient temperature, suitable for high temperature areas.

Low noise and vibration

Scroll compressor runs smoothly without additional sound insulation measures.

Easy Maintenance
Modularized design, compressor can be replaced independently; condenser is easy to clean (removable endcover or automatic cleaning function).
Space saving
Compact structure, covers an area 30%~50% smaller than centrifugal or screw units of the same capacity.

Scroll compressor:

 the core component, gas compression is completed by scroll disk engagement, withsmooth operation, low noise and high effciency.

Water-cooled condenser :

water as the cooling medium, through the shell and tube or plate heat exchanger headissipation, more adapted to high-temperature environments than air-cooled units.

Evaporator :

usually shell and tube tvpe, heat exchange between refrigerant and water, output chilled water.

Microcomputer controller :

adopts large touch screen, with powerful control function and many other functionssuch as fault self-diagnosis.
