The liquid refrigerant is pumped back to the full liquid chiller _ more usable - the oil level detector 212: the height of the frozen lubricating oil of the press 210 To ensure that the oil level is in the forefront. When the oil level is lower than this height, the opening degree of the adjustable flow regulating valve M2 is adjusted to be larger or instantaneously increased, or even fully opened for a predetermined period of time to additionally provide a predetermined auxiliary oil return amount. Referring also to Fig. 4, it is a flow chart of the auxiliary oil return control of the full liquid ice machine of the second preferred embodiment. As shown in the figure, the step starts, the chiller 200' proceeds to step 420, and the pressure detector 216 and the pressure detector 218 are used to measure the high and low pressure of the compressor 210, and the high-pressure value is transmitted.

When the oil level is insufficient, the process proceeds to step 46G to greatly increase the opening degree of the adjustable flow regulating valve 252, 13 1307398 / such as: opening 1 〇 · 3 〇 seconds to make the compressor 21 〇 immediately obtain a larger auxiliary oil return amount ^If the oil level is not insufficient, proceed to step 47, and adjust the adjustable flow regulating valve 252' appropriately according to the required opening degree of the adjustable flow regulating valve 252 in order to make the compressor obtain better. Return oil quantity. The full-liquid ice water machine of the present invention can measure the height of the compressor [[to control the required oil return amount, thereby controlling the adjustable flow regulating valve. The amount of oil returned to meet the compressor load appropriately The demand can not only avoid the phenomenon that the compression and extinguishing oil level is insufficient to jump off the machine', and it is not necessary to excessively increase the oil level, so that the cooling efficiency of the full liquid ice water machine is effectively improved. In combination with the use of the oil level ejector, it is possible to avoid the abnormal shutdown caused by the abnormal oil level of the compressor, and effectively improve the service life of the full-liquid chiller and the overall efficiency of the system. Wherein, the programmable controller of the flooded chiller of the present invention may also utilize a microcomputer controller (Micro_Pr〇cess〇rc〇ntr〇ller) to control the solenoid valve, control the adjustable flow regulating valve, and calculate the compression. The high and low voltages of the machine are not deviated from the spirit and scope of the present invention. Φ The second embodiment of the full-liquid chiller of the present invention can also be mounted thereon by using the second oil return pipe of the first embodiment. When the oil level detector 212 detects that the compressor oil level is insufficient, the priming is started. This second oil return pipe is provided to provide another auxiliary oil return amount to accelerate the supply of the compressor refrigeration oil. At the same time, the full-liquid chiller of the present invention can also measure the oil return of the first return pipe by measuring the high and low pressure difference of the compressor, and then use the oil level detector to detect that the compressor oil level is insufficient. When the second oil return pipe is started to provide an auxiliary oil return amount, thereby achieving the required oil return amount β of the compressor, and the adjustable flow regulating valve of the second embodiment can also be detected only by the oil level detector. When the oil level of the compressor is insufficient, 14 -1307398 according to the calculation of the programmable controller, B Tam will increase the auxiliary auxiliary oil return amount, that is, adjust the opening degree of the adjustable flow regulating valve to increase the oil return amount. And when the position is not insufficient, then the adjustable flow regulation is maintained wider than a predetermined opening... Maintain the compressor oil level at the appropriate height. In addition, the present invention: the number of the return pipe and the second return pipe are not limited to one, the total return pipe - the opening time of the parent port oil officer can also be different according to the needs of the need only 0 of the present invention The liquid ice water machine uses the oil level of the detecting compressor to selectively provide auxiliary oil return to the compressor, so as to ensure the return oil of the increasing domain reducer, thereby protecting the stability and safety of the compressor operation. At the same time, it can also be used with the high and low pressure difference of the measuring compressor to adjust the oil return required by the (four) machine, so that the oil level of the control unit is stabilized at an appropriate level. Therefore, the full liquid chiller of this (4) can effectively improve the efficiency of the chiller and the overall system efficiency of the central air conditioner to achieve the goal of saving energy while improving the service life of the chiller.
