In this study, we applied the multiple control technique to the constant temperature water control, effectively cooling the two constant temperature water baths and controlling them with the final electric heater. The temperature difference of the water bath with VRF and electric heater can be maintained within the same small range as the conventional water bath with a water cooling chiller and electric heater. One VRF system using multiple control technique can not only operate two water baths simultaneously, but also reduce the power consumption by 85.7% at the SP 15℃, 20℃, 25℃.
