LSLG series air source heat pump screw unit have high efficiency ,low noise ,easy operation,simple maintenance etc.

LSLG seriew air-source heat pump screw unit featuer.：

1、Air source heat pump screw have high efficiency ,low noise,easy operation,simple maintenance

etc；

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

long service life feature etc；

3、Condenser and evaporator are made of high efficiency thread tubes,with high quality

refrigeration component,by specialized manufacturing process to manufacture high-proformance

machine；

4、Air source heat pump screw unit adopt famous brand PLC electrical control component,high

quality 64k color touch screen,clear interface,easy operation；

5、Muilt capacity adjustmemt,can meet the cooled change requirement, maximum saving the cost of

operation and maintenance。

The systen control of LSLG series air source heat pump screw unit：

1、Workflow system with image display picture, show the in/out water  temperature, the compressor energy state, open/ stop button, the operation time display, alarm display. With remote open/shutdown function. If it is demand, can realize PC remote control。

2、In order to convenient the maintenance for the user,control system can base on the compressor running time,prompting the user maintenance in suitably。

3、Twin and above compressor unit,control system can automaticlly identify the per compressor running time ,adjust the running time of the compressor,balancing the compressor working time。

The safe protection of Air source heat pump unit：

1、Exhaust non-return valve:Ensure the compressor stop running,prevent the high pressure exhaust gas back.。

2、The phase sequence protection: prevent over-voltage, under voltage, phase lack protection compressor, reverse protection, it prevent the discharged gas from going back after the compressor stop。

3、Oil heater:it heats the oil before the unit start,keep the good lubrication for the unit before it runs。

4、Overheat protection inside the motor of the compressor:it protect the compressor from burning down for too high coil temperature for overload,or abnormal run condition。

5、High and low pressure protection:it protect the compressor and the system ag against extreme run condition and trouble。

6、Safe valve :Ensure the condenser working in the safe range。

7、Freezing protection:During the operation, prevent the water temperature is too low, the formation of local ice damage to the evaporator。

8、Water flow protection: Provent the units from run without water flow。

9、High temperature of chilled water protection:the temperature is to high ,the units work under this condition long time will burn out the compressor ,so do such special protection 。

10、Overload protection:Sofe,hard double protection,ensure the compressor overload safe protection。
