用于冷水机组的无级调节压缩机及其载荷控制方法技术

本发明专利技术公开了一种用于冷水机组的无级调节压缩机及其载荷控制方法，可使螺杆式冷水机组根据实际负荷实现无级容量调节，有利于冷水机组的节能。该压缩机包括低压腔，油腔，油过滤器以及油路系统，油路系统由供油管以及旁通管组成，供油管上安装有控油阀，供油管的一端与油过滤器连通，另一端与油腔连通；旁通管上安装有旁通阀，旁通管的一端与油腔连通，另一端与低压腔连通。载荷控制方法主要是根据冷冻水目标出水温度，补偿温度以及冷冻水实际出水温度的关系通过脉冲信号精确控制压缩机载荷以达到节能的目的，通过上述载荷控制方法，相比现有技术的4级容调冷水机组，可节能5％以上。

Stepless regulating compressor for water chiller and load control method thereof

The invention discloses a stepless regulating compressor for a water chiller and a load control method thereof, which enables the screw type chiller to realize stepless capacity regulation according to the actual load, and is beneficial to the energy saving of the chiller. The compressor comprises a low-pressure chamber, the oil chamber, the oil filter and the oil system, oil system by oil pipe and bypass pipe, oil pipe is installed on the oil control valve, oil filter oil supply pipe at one end and connected, and the other end of the oil chamber; by-pass pipe is provided with a by-pass valve, and one end of the oil cavity bypass pipe the other end is connected with the low pressure cavity communicated with. The load control method is mainly based on the target outlet temperature of chilled water, chilled water temperature and the relationship between the actual compensation water temperature precise control of compressor load to achieve the purpose of saving energy through the pulse signal through the load control method, compared with the prior art, the 4 stage adjustable water chiller, can save more than 5% energy.
