Highly accurate manufacture in machining industry can only be obtained with precise temperature control of the coolant （oil or water）.Machine tool with more accurate,stable and advanced the precision of the working component cannot be developed without appropriate ***,the machine tool coolers are facing the control hunting of cooling temperature and the dramatic variation of heat load in high-accuracy *** main objective of this study is to evaluate the influence of the hot-gas by-pass scheme and suction regulation for capacity control of a machine tool cooler *** this study,experimental investigation on both hot-gas by-pass scheme and suction valve regulation for capacity control has been *** of using capillary tube and thermostatic expansion valve along with different capacity control scheme have been investigated extensively in an environmental testing *** performance and power consumption of the cooler system have been measured and analyzed as well by comparing with different opening percentage of throttling valve under specific coolant *** experimental results reveal that the power consumption will reduce slightly by capacity control using the hot-gas by-pass scheme but the coefficient of performance （COP） of the overall system will *** coolant temperature will result in higher compressor power consumption as *** conducting suction valve regulating for capacity control,energy-saving at 10%-12% can be obtained by using thermostatic expansion valve under different evaporator *** also reveals that suction valve regulation along with adequate choice of thermostatic expansion valve can provide alternative choice for steady capacity control and substantial *** proposed cooler systems with different capacity control schemes are not only more cost-effective than inverter driven system,but also can perform energy-saving and precise temperature control specific for high-accur
