Air Cooled Scroll Chiller

Air cooled scroll chiller is a cost-effective and stable-running HVAC solutions. It’s a small packaged chiller that maximum 16 units can be combined in one system to make a single larger capacity. Air cooled scroll chiller is one of the most traditional HVAC solutions.Air cooled scroll chiller consists of compressor, condenser, expansion device, and evaporator. Air cooled modular chiller has smaller size than standard chillers, It takes less space for installation.Moreover,There is less downtime if one of the modules malfunctions because each module has its own dedicated power to keep running.

Main features:

1. Intelligent defrosting program

Defrosting starts only when the unit need to reducing defrosting time and water temperature fluctuation.

2. Modular design

Max. 32 units can be combined in one group (16 units for 130kW units), max. capacity can be up to 2080kW.

3. Unit back-up function If master unit fails, all the units will stop and any of the slave units can be set as master unit manually. If one slave unit fails, this unit will stop but others keep running.

4.Built-in water flow switch

Standard with high quality water flow switch.Convenient for installation, no need to install water flow switch in water system on site.Realise the function of control every chiller’s water flow precisely

5. High efficiency shell&tube heat exchanger

Shell&tube heat exchanger uses spiral turn-back design and high heat transfer efficiency copper pipes, to avoid rectangular place of dead heat, decrease water pressure drop, improve heat exchange

6. Parallel running system

Efficiency will be increased 12% when one compressor full load running because the condenser area is 2 times than independent running system.

Refrigerant circuit will be simpler and running condition will be more stable.

Independent running system/ Paralel running system

7. Smart motor speed control

Two-speed control independently guarantees the best condenser condition and low consumption.

In part load running condition, the motor will run in low speed and with low consumption

8.Cycle operation

In one combination system, according to unit’s accumulated operation time, all slaver units operates as alternative in cycle, which increases reliability and balances units lifespan.

9.Wide operation range

Operate from -15˚C to 46˚C without failure

10.Unique control logic

When a system with four units running at part load and 4 compressors are needed, in ordinary control logic two units will run at full load but in AIRMYTH control logic, four compressors in four units will run to make full use of all condensers, so the efficiency improves a lot.

11.Round-designed condenser

360° air intake The airflow is evener and heat exchange is more sufficient.

12.CTIG inner-grooved copper tube Higher thermometric conductivity and increases heat-exchanging efficiency.

13.Cross flow fins Low air resistance and great heat transfer coefficient, and frosting improves a lot.

14.Multiple protections

15.High Cooling Performance EER

30KW 60KW 130KW

EVI Modular Chiller

High heating performance

Low temperature heat pump unit adopts EVI technology. Two-stage compression improves heating capacity and efficiency in low ambient temperature.

EVI compressor

Low-temperature heat pump unit adopts EVI (Enhanced Vapor Injection) compressor. A part of drawn intermediate pressure gas refrigerant mixes and compresses with compressed refrigerant, which realizes two-stage compression in one compressor, increases compression efficiency and improves the heating performance in low temperature.

Plate heat exchanger

Plate heat exchanger plays an important role in EVI heat pump unit. Sub-cool the refrigerant before throttling in primary loop, increase enthalpy difference. Preheat the throttled refrigerant in auxiliary loop, supply gas refrigerant to compressor for secondary compression.

Wide operation range

Cooling operating temperature is up to 46℃ Heating operating temperature is down to -30℃

Air-cooled heat pump modular chiller

High Reliability Copeland compressor

Better Liquid Handling Radial compliance allows the scroll members to seperate in the presence of liquid refrigerant,thus, providing protection against luquid damage. Greater Efficiency With axial compliance,optimized force between two scrolls can be obtained,leading to high efficiency over the entire operating range. Unmatched Reliability Ability to start under any system load,without start components. Easy to service and maintain Easy to service and maintain due to their compact size and light weight. Simple design Engineered for optimun performance with todays’s chlorine-free refrigerants.No complex internal suction and discharge valves for quieter operation and higher reliability.

Eco friendly R410A(HFC) refrigerant,low carbon footprint,no harm to the environment.

Larger loading quantity

Optimized structure and compact size provided a larger load quantity,for a 20’container,65kW unit could be loaded 12 sets,and 130kW can be loaded 6 sets.

500 steps EXV from famous brand

Compare to TXV,it controls refrigerant flow as per operation mode and temperature condition,because EXV has faster load reaction speed,bigger regulation range,higher refrigerant control accuracy,so the water outlet temperature can be controlled more precisely

Modular design concept

Modular design concept,a good solution for agencies to make stocks.Excellent flexibility in installation,max.16 units can be combined in a group,max.capacity can be up to 2080kW

Precise temperature control

Precise water perperature control,keeps room temperature stable.compressors in each units auto respond to the real capacity needs ,system provides precisely water temperature controls.

Optimize fan blade design

Optimization of fan blade and fan shroud design,bigger air flow,lower noise.

Balance operation program

Balance operation program,it balances the operation time of every unit according to the unit’s accumulated operation time

Backup function

If master unit fails all the units will stop,any one of the slave units can be set as master unit manually.if one slave unit fails,this unit will stop but others keep running.

Wide operation range

R22,R410a

R407C

Multi Protections

Comprehensive protections to guarantee system’s safety.

Using various protection devices to guarantee the system more safe and reliable.

High pressure switch

Low pressure switch

Compressor current protection

Phase protection

Spiral turn-back plate heat exchanger

The refrigerant flow in traditional bow shaped turn-back flow heat exchanger moves in”Z” path.The new spiral flow design in spiral turn-back plate heat exchanger changes the status and form of refrigerant,thus increasing heat exchange efficiency. The main characteristics of spiral turn-back plate heat exchanger are as below:

1.high heat transfer coefficient(20%~40% increase); 2.Full coverage of heat exchange.without dead heat;

3.Obvious decrease of pressure drop in the shell(around 45% drop pressure under the same flow velocity);

4.Few impurities are no retention area in the shell; 5.Better anti-vibration

High efficiency condenser Refrigerant flow paths are optimized design,especially for the lower part of condenser coil,it evens the heat exchange between upper part and lower part of condenser ,to improve the efficiency of whole unit,also improve the defrosting efficiency in cold winter.

High efficiency evaporator

High efficiency shell & tube evaporator,fouling factor is 0.086m2 *℃/kW,high heat transfer efficiency copper pipes are used in the heat exchanger
