The system characteristics  of the LSLG series screw heat

pump unit：

1、Heat pump unit have high efficiency ,low noise,easy operation,and simple maintenance etc；

2、Adopt world well-know brand twin screw compressor,high efficiency.low noise ,less wearing

,easy operation and long operateion time；

3、Condenser,evaporators are made of efficient threaded copper tubes ,with high components, by

specialized manufacturing process to  manufacture high performance machine；

4、Screw Heat pump unit adopt well-know brand PLC and electrical components ,high quality 64k

color touch screen,clear interface and easy operartion；

5、Muilt capacity adjustment can meet the cold change requirement.Maximun saving the

maintenance and operation cost。

LSLG series screw heat pump unit system control：

1、Lmages system operation chat ,show the tenperture of water in and out,the energy level of

compressor run,on/off button,run time,alarm .Have remov e turn on /off function,PL remote

control is optional.。

2、For convenient the user maintenance the unit ,the control system according to accumlated the

run time of the compressor , prompt the user maintenance。

3、Double and above compressor unit,control system will automatically run time for each of the

compressor,adjust and  balance each compressor run time。

LSLG series screw heat pump unit safety protection：

1、Discharge check valve :Prevent the discharge gas from going back after the compressor stop。

2、Phase lack protection:it protect the compressor for over high voltage、voltage deficiency

amd phase lack.Reverse protection, prevent to damage the compressor。

3、Oil heater:befor run the machine,forcing set oil heating program time,ensure the dilution

level and the flowability of the oil,keep the good lubrication for  the compressor。

4、Overheat protection inside the motor of the compressor:protect the compressor from burning

down for too high coil temperture for the overload ,or abnormal run condition。

5、High and low pressure protection:it protect the compressor and the system against extreme

run condition。

6、Safety valve:Ensure the condenser work in a safe range。

7、Freezing protection:It provents the water temperture too low ,the formation of local ice

damage to the evaporator。

8、Water flow protection :provent the unit water-break work。

9、High temperture of chilled water protection: the unit overload,will make the chilled

temperture doesn't fall ,the unit long time run under this term will burn the compressor,so

have this special protective。

10、Overload protective:soft ,hard double protective ,ensure the compressor overload safety

protective。
